Description

  The present invention relates to a ball game machine that plays a game by firing a game ball toward a game board surface.

  When a game ball is launched on a game board surface provided with a plurality of entrances, and a game ball enters one of the entrances, a predetermined number of game balls are paid out as prize balls. Various types are known. Today, among these ball game machines, a so-called “seven machine” is widely used.

  This ball game machine called a seven machine is provided with a special entrance called a start opening, and a big hit lottery is performed when a game ball enters the start opening. When the big hit lottery is won, the big hit game is started and a large amount of game balls are paid out to the player. In such a ball game machine, when the big hit game ends, the state where the game ball is likely to enter the start opening (easy entry state) and the probability of winning the big hit lottery (high probability state) And improve the game fun of the player.

  In addition, in such a ball game machine, in a state where the easy-to-enter state and the high probability state are generated, a falling lottery that falls from the high probability state to the low probability state regardless of the execution of the big hit game is performed. It has been proposed to change the game in the easy entry state. (For example, patent document 1).

JP 2005-296076

  However, in the above-described conventional technology, even if the winning lottery is won, the probability of winning the big hit lottery is reduced, and only a disadvantage is caused for the player. For this reason, even if a falling lottery is provided, the player's gaming interest has not been effectively enhanced.

  The present invention was made to solve the above-mentioned problems of the prior art, and utilizes the function of falling from a state in which a hit game is executed with a high probability to a state in which it is executed with a low probability, An object of the present invention is to provide a ball game machine capable of exciting a player's gaming interest.

In order to solve at least a part of the above-described problems, the bullet ball game machine of the present invention employs the following configuration. That is,
A start opening provided for allowing a game ball launched on the game board surface to enter,
A hit / fail determining means for determining whether or not the game ball is hit by entering a game ball at the start opening,
A hit game executing means for executing a hit game when the hit is determined by the hit / fail determining means,
When the winning game ends, a high probability state in which the probability that the winning / failing determination is determined is higher than the normal state is generated, and the game ball is more likely to enter the starting port than in the normal state. In a ball game machine that controls the progress of a game so that a ball easy state is generated over a predetermined game period,
In the state in which the high probability state and the easy entry state have occurred, a specific condition excluding the execution of the winning game is satisfied, the high probability state is terminated, and only the easy entry state has occurred. High probability state termination means to
The state when the winning is determined by the hit / fail determining means is any of the state in which the high probability state and the easy entry state have occurred, and the state in which only the easy entry state has occurred. Accordingly, it is characterized by comprising game progress control means for controlling the progress of the game so that the amount of profit given to the player in accordance with the execution of the winning game is different.

  In the ball game machine of the present invention having such a configuration, when the hit game is completed, the game ball easily enters the start port until the predetermined number of games are consumed (easy to enter), A gaming state (high probability state) having a high probability that the winning is determined (the probability that the winning game is executed) occurs. And if a specific condition is satisfied while it is in the easy-to-enter state, the high-probability state ends, and the game state (low-probability state) shifts to a low probability of winning (probability of winning a winning game). (Fall down). In addition, the period during which it is easy to enter the ball is in a high probability state (hereinafter also referred to as “period before falling”) and the period during which it is easy to enter the ball are in a low probability state (hereinafter referred to as “period after falling”). )), The profit to be given to the player in accordance with the execution of the winning game is determined according to which period the “winning” is determined (that is, whether the winning game is determined to be executed). The size changes. For example, when a game is executed in the “period after falling (a period in which it is easy to enter a ball and the period is in a low probability state)”, It is conceivable to give a profit that is advantageous to the player as the winning game is executed rather than the winning game being executed in the “period)”. In this case, after starting the easy-to-enter state, expect the player to fall to a low probability state as soon as possible (for example, to win the falling lottery) and continue the game, after falling (for example, after winning the falling lottery) ) Will continue the game in the hope that the winning will be determined (if the winning is determined by winning the big win lottery, the lottery will be won). On the other hand, when a game is executed in the “period before falling”, a profit that is advantageous to the player is given in connection with the execution of the hit game rather than in the “period after falling”. It is also possible to do. In this case, the game is continued with the expectation that the winning is determined as soon as possible after the start of the easy entry state. As described above, according to the present invention, it is possible to realize a novel game characteristic that “the player's expectation target hits and affects other than the execution of the game as the game progresses”. In other words, according to the present invention, the falling in the easy entering state (falling lottery) is not simply disappointed if the falling (winning), but it is also an element that makes the easy entering state more varied. Therefore, it is possible to greatly excite the player's gaming interest.

  Note that the “specific condition” referred to here may not be constant when the “specific condition” is satisfied. For example, when a lottery is made each time it is determined whether to win or not, and the lottery is won, a specific condition is satisfied (when a so-called falling lottery is performed), or staying in a high probability state when shifting to a high probability state For example, the length of the period to be played (the number of times of games, so-called number cut) is determined from a plurality of candidates (by lottery or the like), and the specific condition is satisfied when the period elapses.

Further, the “entry easy state” mentioned here may be any as long as the number of game balls to be paid out increases from the normal amount because it becomes easier for the game ball to enter the starting port than usual. For example, “Easy to enter” is
A passing gate provided on the surface of the game board so that a game ball launched on the surface of the game board can pass;
When the game ball passes through the passing gate, the normal symbol change display is started, and when the predetermined normal symbol change time elapses, the normal symbol display device that stops and displays the normal symbol in either the winning symbol or the off symbol,
It is configured to be switchable between a normal state in which a game ball can enter and an open state in which the game ball can enter more easily than the normal state. A starting opening that is open for a period of time;
When the big hit game ends, the opening opening time may be realized by providing an opening extension means for setting the opening time of the start port to an extension opening time that is an opening time extended from the normal time.

  In addition, “control the progress of the game so that the amount of profit given to the player with the execution of the winning game is different” is referred to as “opening the big prize opening in the winning game executed in each state” Number of rounds, number of rounds, number of winning balls when a single game ball enters the winning prize opening, maximum number of winning balls for opening one big winning opening, opening time for opening one big winning opening, etc. To make a difference in the number of game balls to be paid out in a single game, or “the period of easy entry after the game is completed in each state (game) For example, it is possible to create a difference in length in the number of

In addition, in such a ball game machine of the present invention,
When the high probability state and the easy entry state are started, the high probability state and the easy entry state have occurred, and only the easy entry state has occurred, Advantageous period determination means may be provided for determining in which state an advantageous period with a large profit to be given when the winning game is executed is generated.

  In the ball game machine having such a configuration, only the high probability state and the easy entry state occur and the easy entry state occur at the start of the high probability state and the easy entry state. One of the states is determined as “an advantageous period in which a profit given with the execution of the winning game is large”. In this case, the total game period in either the high probability state or the easy entry state or the only easy entry state may be set as the advantageous period (for example, the incoming game) The entire game period in which only the easy state has occurred is regarded as the advantageous period, etc., or a part of the game period in any state may be defined as the advantageous period (for example, the first half in the state where only the easy entry state has occurred For example, the game period of the portion is set as an advantageous period). Moreover, you may alert | report to a player which state is set to the advantageous period, and you may make it non-notify | report. When notifying the player of which state is set to the advantageous period, the player advances the game in the hope that the winning game will be executed in the state set to the advantageous period. . Further, when not informing the player of which state is set to the advantageous period, the game is advanced with the expectation that the profit given in the winning game execution is large. As a result, it is possible to make the above-described game characteristics more varied and to further enhance the player's gaming interest.

In addition, in such a ball game machine of the present invention,
When the high-probability state and the easy-to-enter state are started, the high-probability state ending means can establish the specific condition that is satisfied when the high-probability state ending means ends the high-probability state. It is good also as providing the termination possibility determination means determined from (1).

  In the ball and ball machine having such a configuration, in addition to which state is set to the advantageous period, a specification for ending the high probability state in the state where the high probability state and the easy entry state have occurred The possibility of satisfying the condition (for example, the winning probability of the falling lottery) changes. As a result, the degree of expectation that the hit game is executed in a state where the high probability state and the easy entry state occur, and the expectation that the hit game is executed in a state where the low probability state and the easy entry state occur are various. It becomes different, and it becomes possible to make the above-described gameability richer in contents and to further increase the game interest of the player.

  Further, the bullet ball game machine of the present invention, the symbol display device capable of variably displaying the symbol, and in the symbol display device, when the game ball enters the start opening, the symbol variation display is started, In the case of providing a symbol display means for stopping and displaying the winning symbol corresponding to the winning result when the winning is determined, the above-mentioned advantageous period determining means displays the winning symbol corresponding to the winning result. Accordingly, it may be determined whether or not the high probability state and the state in which the easy entry state has occurred are set as the advantageous period. Further, the termination possibility determining means described above may determine the possibility of establishment of the specific condition according to the corresponding symbol.

  In a ball game machine having such a configuration, depending on the type of winning symbol, after the winning game is finished, it is determined which state the advantageous period is and how likely it is to fall. Therefore, it is possible to increase the player's degree of attention to the winning symbol and to change the target of the player's expectation in the subsequent easy entry state for each winning symbol. As a result, it is possible to make the player feel that there are a plurality of easy-to-enter states with different profit rates and expectation levels for each symbol, and it is possible to greatly excite the game.

  According to the present invention, a player's game during a period in which it is easy for a game ball to enter the starting port by utilizing a function of falling from a state in which a hit game is executed with a high probability to a state in which the game is executed with a low probability. A ball game machine that can excite interest can be provided.

The ball lending device 13 pays out a ball while exchanging data with the payout control board 240. When the main control board 200 outputs a prize ball payout command, the payout control board 240 receives this command and outputs a drive signal to the payout motor 109m to pay out the prize ball.

A-2. Overview of the game:
Next, the outline of the game performed in the pachinko machine 1 of the first embodiment having the above-described configuration will be briefly described. In the pachinko machine 1 of the first embodiment, a game is performed as follows. First, when a player throws a game ball into the recess of the upper plate portion 5 and rotates the launch handle 8, the game balls thrown into the upper plate portion 5 are supplied to the launcher unit 12 one by one, The game area 11 is fired as described above with reference to FIG. The strength at which the game ball is launched can be adjusted by the rotation angle of the launch handle 8, and the player can aim the launch position of the game ball by changing the rotation angle of the launch handle 8. Can do.

  When the launched game ball passes through the normal symbol operation gate 36 provided on the left side of the game area 11, the special symbol display device 28 starts the variation display of the normal symbol. As described above with reference to FIG. 3, the special symbol display device 28 is provided with the normal symbol display unit 29, and the normal symbol display unit 29 is mounted with the normal symbol LED 29a and the universal symbol hold display LED 29b. . Of these, the normal symbol LED 29a is used to display the variation of the normal symbol.

  FIG. 6A is an explanatory diagram conceptually showing a state in which normal symbols are variably displayed. In the pachinko machine 1 according to the first embodiment, the normal symbol LED 29a is repeatedly blinked to display the normal symbol variation. In the figure, the state in which the normal symbol LED 29a is lit is represented by a radial solid line, and the state in which the normal symbol LED 29a is lit is represented by a broken line. When the blinking normal symbol LED 29a stops in a lighting state, the normal symbol is a hit and the start port 17 is opened for a predetermined time (for example, 0.5 seconds). On the contrary, when it stops in the light-off state, it will be out of the normal design and the starting port 17 will not be opened. If the game ball passes through the normal symbol operation gate 36 during the normal symbol variation display, the passage of this game ball is stored as the number of holdings, and after the current normal symbol variation display is completed, the variation display is performed. Is done. Up to four normal symbols can be stored, and the number of stored normal symbols is displayed by the general symbol display LED 29b.

  FIG. 6B is an explanatory view showing a state in which the number of normal symbols held is displayed by the universal symbol hold display LED 29 b provided in the special symbol display device 28. When there is no normal symbol hold (that is, when the number of hold is zero), both of the two normal figure hold display LEDs 29b are turned off. When there is one hold, the left-hand general map hold display LED 29b remains off and the right-hand general map hold display LED 29b is lit. When there are two holds, the left-hand general map hold display LED 29b is lit in addition to the right-side normal map hold display LED 29b. Next, when there are three holds, the right-hand general map hold display LED 29b blinks and the left-hand general map hold display LED 29b lights. When the number of hold increases further to the upper limit of four, the left and right map hold display LEDs 29b blink. In this way, the normal symbol display unit 29 can display the number of holds from 0 to 4 by turning on, turning off, or blinking the two common figure hold display LEDs 29b.

  Further, as described above with reference to FIG. 3, the special symbol display device 28 is provided with the special symbol display unit 30. When a game ball enters the start port 17, the special symbol display is started. After that, it is stopped and displayed with any of the symbols described below.

  FIG. 7 is an explanatory view conceptually showing a stop display mode of special symbols. As described above with reference to FIG. 3, the special symbol display unit 30 includes seven LEDs, and displays these special symbols by lighting them. As shown in FIG. 7, in the pachinko machine 1 of the first embodiment, eight types of special symbol stop display modes are provided, and a unique lighting state is set for each stop display mode. . Further, the stop display modes of these eight kinds of special symbols are roughly classified into two symbols. First, the stop display modes of the six special symbols shown in the upper part of the figure are classified as “big hit symbols”, and the stop display modes of the two special symbols shown in the lower part are classified as “off symbol”. .

  The special symbol display unit 30 performs a special symbol variation display by blinking seven LEDs (special symbol LEDs 30a) for a predetermined time, and when the predetermined time has elapsed, the special symbol display unit 30 is stopped and displayed according to any stop display mode. Then, when any of the jackpot symbols is stopped and displayed, the jackpot 31d is opened and the jackpot game is started. In addition, as will be described in detail later, after the jackpot game is over, even if the jackpot game is started by any of the jackpot symbols being stopped and displayed, until the winning lottery described below is won, The probability that the special symbol is stopped and displayed in the big hit symbol (the winning probability of the big hit lottery described later) is set to a state (high probability state) in which the probability is set higher than normal (low probability state). Here, in the first embodiment, the special symbol display unit 30 is configured by seven LEDs, and various hit symbols and off symbols are displayed by the display patterns of these LEDs. It may be composed of one or a plurality of (for example, two) 7-segment displays, and various jackpot symbols and missed symbols may be displayed according to a 7-segment display pattern. Moreover, you may make it display also about display numbers (for example, 7 segment display) other than LED also about the number of reservations of a normal symbol, a special symbol, and the number of reservations of a normal symbol.

  In addition, even when a game ball that has entered the start port 17 is detected by the start port switch 17s, the special symbol variation display cannot be started (for example, when the special symbol variation display is being performed, or a big hit Even if the game is in progress), the fact that a game ball has entered the start port 17 is stored as a special symbol hold (special figure hold). For this reason, it is possible to perform the variable display using the stored hold when the special symbol can be displayed in a variable manner. The number of special figure reservations stored (the number of special figure reservations) is displayed by the special figure reservation display LED 30b. The mode of displaying the number of special figure hold using the special figure hold display LED 30b is exactly the same as the case of the general figure hold display LED 29b shown in FIG.

  In accordance with the special symbol variation display and stop display on the special symbol display device 28 described above, the effect symbol display device 27 performs various effects using the identification symbol. FIG. 8 is an explanatory diagram illustrating an aspect of the effect performed by the effect symbol display device 27. As described above with reference to FIG. 4, the three identification symbols 27 a, 27 b, and 27 c are displayed on the liquid crystal display screen constituting the effect symbol display device 27. When the variation display of the special symbol is started by the special symbol display device 28 described above, also in the effect symbol display device 27, these three identification symbols 27a, 27b, and 27c start the variation display all at once. In the present embodiment, a design in which six numbers from “1” to “6” are designed as identification symbols is prepared. Note that the identification symbol may be a symbol, character, graphic, symbol, or the like as a design other than numbers, and may be in any form that allows the player to identify whether the special symbol is appropriate or not.

  FIG. 8A conceptually shows a state in which the three identification symbols 27a, 27b, and 27c are variably displayed at the same time. When a predetermined time elapses after the variable display is started, the left identification symbol 27a is first stopped and displayed as any one of “1” to “6”, and then the right identification symbol 27c is stopped and displayed. The middle identification symbol 27b is stopped and displayed. The combination (stop display mode) of the three identification symbols 27a, 27b, and 27c that are stopped and displayed on the effect symbol display device 27 is interlocked with the combination of the special symbols that are stopped and displayed on the special symbol display device 28 described above. It is configured. In particular, when the special symbol of the special symbol display device 28 stops at the jackpot symbol, the three identification symbols 27a, 27b, and 27c of the effect symbol display device 27 are all stopped and displayed together. On the other hand, when the special symbol of the special symbol display device 28 is out of position and stops at the symbol, the three identification symbols 27a, 27b, and 27c are stopped and displayed in any combination that does not align with the same symbol.

  Thus, the display content on the special symbol display device 28 and the display content on the effect symbol display device 27 correspond to each other. Furthermore, the timing at which the special symbol on the special symbol display device 28 is stopped and displayed, and the timing at which the three identification symbols 27a, 27b, and 27c on the effect symbol display device 27 are stopped and displayed are also set to be the same. Moreover, as shown in FIG. 2, the effect symbol display device 27 is provided at a position that is more easily noticeable than the special symbol display device 28, and the display screen is large and the display content is easy to understand. It is normal to play a game while looking at the screen of the effect symbol display device 27. Therefore, when the left identification symbol 27a initially stopped and displayed on the display screen of the effect symbol display device 27 and the right identification symbol 27c subsequently stopped and displayed are the same symbol, the display is stopped at the end. In other words, the player pays attention to the variation of the symbols so that the middle identifying symbol 27b may stop at the same symbol and enter a so-called jackpot gaming state. In this way, the effect of variably displaying the last symbol in a state where the two symbols are stopped at the same symbol (the state where the symbol is stopped by the symbol constituting the hit display mode) is called a reach effect. It is possible to enhance the interest of the player by directing.

A-3. Control details of pachinko machine:
Below, in order to implement | achieve the game mentioned above, the control content which the pachinko machine 1 of 1st Example is performing is demonstrated in detail.

A-3-1. Game control processing:
FIG. 9 is a flowchart showing a rough flow of the game control process performed by the CPU 201 of the main control board 200 for controlling the progress of the game in the pachinko machine 1 of the first embodiment. As shown in the figure, in the game control process, each process such as a prize ball related process, a normal symbol game process, a special symbol hold process, a special symbol game process, a special electric game game process, and the like is repeatedly executed. The time required for one round of processing is about 4 msec. Therefore, these various types of processing are repeatedly executed about every 4 msec. Then, during these processes, various commands are transmitted from the main control board 200 to the various control boards including the sub control board 220. By doing so, the game of the entire pachinko machine 1 proceeds, and the sub-control board 220 controls the production in accordance with the progress of the game. Hereinafter, the game control process performed by the CPU 201 of the main control board 200 will be described according to the flowchart.

  When starting the game control process, the CPU 201 of the main control board 200 performs a process (pay ball related process) for paying out a game ball as a prize ball (S50). In this process, among the various switches connected to the main control board 200, whether a game ball has entered a game ball winning switch (such as the start opening switch 17s, the big winning opening switch 31s) (game ball). Is detected). When a game ball is detected, the number of prize balls to be paid out is calculated, and then a process for transmitting a prize ball number designation command to the payout control board 240 is performed. When the payout control board 240 receives the award ball number designation command transmitted from the main control board 200, the payout control board 240 interprets the contents of the command, and transmits a drive signal to the payout motor 109m mounted on the payout device 109 according to the result. Thus, a process of actually paying out the prize ball is performed. When the CPU 201 of the main control board 200 performs the prize ball related process (S50), this time, the normal symbol game process is started (S150).

A-3-2. Normal design game processing:
FIG. 10 is a flowchart showing the flow of the normal symbol game process performed in the game control process. As shown in the drawing, in the normal symbol game process (S150), first, it is determined whether or not the game ball has passed through the normal symbol operation gate 36 (S200). As described above, the normal symbol operation gate 36 is provided with the gate switch 36s for detecting the passage of the game ball, thereby detecting that the game ball has passed the normal symbol operation gate 36. Can do.

  When the passage of the game ball is detected by the gate switch 36s and it is determined that the game ball has passed through the normal symbol operation gate 36 (S200: yes), the number of normal symbols held (the number of normal symbol holds) is the upper limit value ( In this embodiment, it is determined whether or not “4”) has been reached (S202). If the number of pending maps has not reached the upper limit value (S202: yes), the routine drawing lot random numbers are acquired and stored in the RAM 203 of the main control board 200 (S204). Here, the regular lottery random number is a random number used for performing a lottery (winning lottery) of winning or losing when a normal symbol is variably displayed. In addition, if the ordinary drawing lottery random number is stored, the number of ordinary symbols held increases by one, so “1” is added to the number of ordinary drawings held (S206).

  On the other hand, when the game ball does not pass through the normal symbol operation gate 36 (S200: no), or when the number of ordinary figure reservations reaches the upper limit (S202: no), the ordinary figure lottery random number is acquired. It is determined whether or not the starting port 17 is open (S208) without performing the storing process (S204) or the process of adding "1" to the number of reserved drawings (S206). As described above, the start port 17 is opened when the normal symbol hits and stops at the symbol. Further, in the processing after the normal symbol game processing, the normal symbol variation display and stop display are performed. However, if the start port 17 is already in the open state, even if the normal symbol is stopped and displayed in the stop symbol, the open state is overlapped. It cannot be. Therefore, if the start port 17 is open (S208: yes), the normal symbol game process is terminated without performing the normal symbol fluctuation display or stop display, and the game control process of FIG. Return.

  On the other hand, when the start port 17 is not open (S208: no), it is determined whether or not the normal symbol is being displayed in a variable manner (S210). As described above with reference to FIG. 3, the symbol display device 28 is provided with the normal symbol display unit 29, so that the normal symbol can be variably displayed. At this time, if the normal symbol is not variably displayed (S210: no), next, during the time when the normal symbol is stopped and displayed so that the player can confirm the stop mode (stop time of the normal symbol) It is determined whether or not (S212). If it is determined that the normal symbol is not in a variable display and the normal symbol stop time has elapsed (S212: no), it is further determined whether or not the normal symbol hold remains (S214). . As described above, the temporary map hold can be stored until the upper limit value “4” is reached. Then, if there is no ordinary figure hold (S214: no), the normal symbol game process is terminated as it is, and the process returns to the game control process shown in FIG.

  On the other hand, if there is a general symbol hold (S214: yes), the oldest general symbol lottery random number stored in the RAM 203 of the main control board 200 is read (S216), and then the normal symbol is variably displayed. Processing is started (S218). In this process, a winning lottery is performed using the oldest usual lottery random number read in the process of S216, and it is determined whether or not the obtained lottery result is “winning”. If the result of the normal symbol winning lottery is “winning”, the stop symbol of the normal symbol is determined to be the winning symbol (the normal symbol LED 29a is lit). On the other hand, when the result of the winning lottery is “disappear”, the stop symbol of the normal symbol is determined as a dismissal symbol. When the stop symbol of the normal symbol is determined according to the result of the normal symbol winning lottery, the variation time is set, and the normal symbol display unit 29 of the symbol display device 28 starts the variable symbol display.

  As above, the process performed when the normal symbol is not in the variable display (S210: no) has been described in detail. On the other hand, when the normal symbol is being displayed in a variable manner (S210: yes), it is determined whether or not the normal symbol change time has passed (S220). If it is determined that the normal time fluctuation time has not elapsed (S220: no), the normal symbol game process is terminated as it is, and the process returns to the game control process shown in FIG.

  On the other hand, when it is determined that the normal symbol change time has elapsed (S220: yes), the normal symbol that is variably displayed on the normal symbol display unit 29 of the symbol display device 28 is determined in advance. The symbol is stopped and displayed at the symbol (winning symbol or off symbol) (S222), and the stop time of the normal symbol (the time during which the normal symbol is stopped and displayed) is set (S224). Then, it is determined whether or not the set stop time of the normal symbol has passed (S226), and if the stop time has not yet passed (S226: no), the normal symbol game process is terminated as it is, and FIG. Return to the game control process.

  On the other hand, when the stop time of the normal symbol has passed (S226: yes), it is determined whether or not the normal symbol that is stopped and displayed is a winning symbol (S228). If the normal symbol is a stop symbol and the symbol is stopped (S228: yes), it is then determined whether or not the release extension flag is set to ON (S230). Here, the open extension flag is a flag indicating whether or not the time (open time) for maintaining the open state when the start port 17 is in the open state is extended, and the open extension flag is set to ON. Then, the opening time is extended. As will be described in detail later, the release extension flag is set to ON when the jackpot game ends, and is set to OFF when a predetermined number of games have ended or a new jackpot game has started. ing. Note that a predetermined address of the RAM 203 of the main control board 200 is assigned to the release extension flag.

  If the result of determination in S230 is that the release extension flag is not set to ON (S230: no), the opening time of the start port 17 is set to the normal time (S232). On the other hand, when the release extension flag is set to ON (S230: yes), the opening time of the start port 17 is set to the extension time (S234). In this embodiment, the normal opening time is set to 0.5 seconds. Further, the extended opening time is set to 6 seconds. Therefore, when the opening extension flag is set to ON, the opening time of the start port 17 is extended. Here, as a mode in which the start port 17 is opened for the extended time (6 seconds), it may be simply opened for 6 seconds, or the operation of opening it for 2 seconds may be repeated three times. Hereinafter, the extension of the opening time of the start port 17 when the opening extension flag is set to ON is also referred to as “the opening time extension function is activated”.

  As described above, during the period in which the release extension flag is set to ON (hereinafter referred to as “open extension period”), the opening time of the start port 17 is extended, so that game balls frequently win the start port 17. As a result, more game balls are paid out than usual. Therefore, the player can progress the game with almost no game balls (at least without reducing the game balls than usual).

  On the other hand, when the normal symbol comes off and is stopped and displayed as a symbol (S234: no), the normal symbol game process is terminated without opening the start port 17, and the game control process of FIG. Return.

  In the game control process shown in FIG. 9, when the normal symbol game process is completed, it is determined whether or not the start port 17 is open (S190). If it is being opened (S190: yes), a process (starting port returning process) for returning the opened starting port 17 to the normal state is performed (S200). On the other hand, when the start port 17 is not open (S190: no), it is not necessary to perform the start port return process, and the process is skipped.

  In the starting port return process (S200), if any of the following conditions is satisfied, that is, whether the opening time of the starting port 17 has elapsed, or whether a prescribed number of game balls have entered the starting port 17 When any of the above conditions is satisfied, a process of returning the start port 17 in the open state to the normal state is performed. On the other hand, when the opening time of the start port 17 has not elapsed and the number of balls entering the start port 17 has not reached the specified number, the start port return process (S200) is performed while the start port 17 remains open. finish.

  In the game control process, when returning from the start port return process, the following process related to special symbol hold (special figure hold related process) is started. In addition, when it is determined in S190 that the start port 17 is closed and the start port return process (S200) is not performed (S190: no), the special figure hold related process described below is performed. (S300) is started.

A-3-3. Special figure hold related processing:
FIG. 11 is a flowchart showing special figure hold related processing. In the special figure holding related process, first, it is determined whether or not a game ball has entered the start port 17 (that is, whether or not a game ball has been detected by the start port switch 17s) (S302). As a result, when a game ball enters the start port 17 (when a game ball is detected by the start port switch 17s) (S302: yes), the number of special symbols held (the number of special figure holds) is the upper limit value. It is determined whether or not (4 in this embodiment) has been reached (S304). If the special figure holding number has not reached the upper limit value (S304: no), a random number for special symbol lottery is acquired and stored in the RAM 203 mounted on the main control board 200 (S306). Here, as the random numbers for the lottery of the special symbol, the big hit lottery random number used for performing the big hit lottery described later, the big hit symbol determination random number used for determining the big hit symbol to be stopped and displayed by the special symbol display device 28, Then, various random numbers such as a reach random number for determining whether or not to perform a reach effect on the effect symbol display device 27 are acquired. The lottery random number obtained in this way is stored in the RAM 203 mounted on the main control board 200 as a special symbol hold (special figure hold). When the acquired random number for lottery is stored as a special figure hold, “1” is added to the special figure hold number (S308), and a hold command is transmitted to the sub-control board 220 in order to transmit that the special figure hold number has increased. (S310).

  As described above, after the hold command is transmitted (S310), the special figure hold related process shown in FIG. 11 is terminated and the process returns to the game control process of FIG. On the other hand, when the game ball is not in the start port 17 and therefore the game ball is not detected by the start port switch 17s (S302: no), the special figure holding number is the upper limit (here, If it has reached "4") (S304: yes), the special command hold related process shown in FIG. 11 is terminated without transmitting the hold command, and the process returns to the game control process of FIG. When returning from the special figure hold-related process, the special symbol game process described below is started in the game control process.

A-3-4. Special design game processing:
12 and 13 are flowcharts showing the special symbol game process. When the special symbol game process is started, it is first determined whether or not a big hit game is being played (S322). If it is a big hit game (S322: yes), the special game process is terminated as it is, and the process returns to the game control process of FIG. On the other hand, when the big hit game is not being played (S322: no), it is determined whether or not the special symbol is changing (S324). As described above with reference to FIG. 3, in the pachinko machine 1 according to the first embodiment, the special symbol display device 30 is provided with the special symbol display unit 30, and the special symbol (hereinafter, sometimes referred to as a special symbol). ) Can be displayed in a variable manner.

  If the special symbol is not changing (S324: no), it is determined whether or not it is during the stop display time for displaying the special symbol stop symbol (S326). That is, for a period of time after the change display of the special symbol is finished, a stop display time is provided for the player to confirm which symbol the special symbol is stopped and displayed. It is judged whether it is in the middle. When it is confirmed that the special symbol is not variably displayed and the stop display time for displaying the special symbol stop symbol has elapsed (S326: no), the number of special symbols held (special symbol hold) It is determined whether or not (number) is “0” (S328). As described above, the special figure holding number can be stored until the upper limit value “4” is reached. If the special figure holding number is “0” (S328: yes), the special symbol game process is terminated as it is, and the process returns to the game control process shown in FIG. On the other hand, when the number of special symbol hold is not “0” (S328: no), the processing for starting the special symbol variation display (special symbol variation display processing) is started (S330).

  FIG. 14 is a flowchart showing the first half of the special figure fluctuation display process, and FIG. 15 is a flowchart showing the second half of the special figure fluctuation display process. As shown in the figure, when the special figure variation display process is started, first, a process for reading the random number for lottery stored the oldest is performed (S3300). As described above, a lottery random number such as a jackpot lottery random number, a jackpot symbol determination random number, a reach random number, or the like is stored as a lottery random number, and a process of reading these together is performed. Subsequently, it is determined whether or not the current gaming state is a high probability state, that is, whether or not the high probability flag is set to ON (S3302). As described above, the high probability state is a state in which the probability that the special symbol is stopped and displayed with the big hit symbol (the winning probability of the big hit lottery described later) is set higher than the low probability state. The high probability flag is a flag that is set to ON when the gaming state becomes a high probability state, and a predetermined address of the RAM 203 mounted on the main control board 200 is assigned as the high probability flag.

  If the current gaming state is not the high probability state (S3302: no), the low probability state is selected, so the low probability jackpot lottery table is selected (S3312). On the other hand, if the current gaming state is a high probability state (S3302: yes), a falling lottery is performed (S3304). The falling lottery is a lottery for determining whether or not to shift the current gaming state from a high probability state to a low probability state (so-called falling). As a result, when the falling lottery is not won (S3306: no), the high probability state is maintained, and therefore the high probability big hit lottery table is selected (S3310). Here, the jackpot lottery table is a table in which lottery results of the jackpot lottery are set in association with the jackpot lottery random numbers, and is stored in advance in the ROM 202 of the main control board 200. The random value associated with the lottery lottery result becomes the “big hit random value” used as the specific random value for the determination of specific hold.

  FIG. 16 is an explanatory diagram illustrating a big hit lottery table stored in the pachinko machine 1 according to the first embodiment. FIG. 16A shows a jackpot lottery table for low probability, and FIG. 16B shows a jackpot lottery table for high probability. As shown in the drawing, in the jackpot lottery table, lottery results of “hit” or “out” are set in association with the jackpot lottery random numbers. As is clear from comparison between FIG. 16A and FIG. 16B, the high-probability big hit lottery table shown in FIG. 16B has the low probability shown in FIG. The lottery result of “big hit” is set to a larger number of random numbers than the big hit lottery table. In other words, a larger number of “big hit random numbers” is set in the high probability big hit lottery table than in the low probability big hit lottery table. In this embodiment, the number of jackpot random numbers in the jackpot lottery table for low probability is set to “12 (values 13 to 24)”, and the jackpot probability in the low probability state is “12/630 (= About 1/53) ". Further, the number of jackpot random numbers in the jackpot lottery table for high probability is set to “14 (values 13 to 26)”, and the jackpot probability in the low probability state is “14/630 (= about 1/45). " As described above, the pachinko machine according to the present embodiment has a smaller difference in the jackpot probability between the low probability state and the high probability state than the general pachinko machine. This is a design for effectively implementing “unique game play” obtained by generating a big hit at an appropriate frequency even in a low probability state (particularly in a low probability state in the extended extension period). The unique game characteristics obtained by this design will be described later.

  The above is the processing when the current gaming state is a low probability state (S3302: no in FIG. 14) and when the current gaming state is a high probability state and the winning lottery is not won (S3306: no). Explained. On the other hand, when the game state is in a high probability state, a fall lottery is won (S3306: yes), and a process for falling is performed when shifting to a low probability state (falling process, S3308). Although details will be described later, in this process, a process of setting a high probability flag to OFF is performed in order to shift the gaming state to the low probability state. When the fall process is completed, the low probability jackpot lottery table shown in FIG. 16A is selected to shift to the low probability state (S3312).

  As described above, in this embodiment, in the case of a high probability state, a lottery lottery is performed for each game (every special map variation display process), and a process for transitioning to a low probability state when the falling lottery is won. I do. The process of setting the high probability flag to OFF regardless of the execution of the big hit game by winning in the falling lottery and shifting the game state from the high probability state to the low probability state is performed by the CPU 201 mounted on the main control board 200. Is done by. Therefore, the CPU 201 mounted on the main control board 200 corresponds to the “high probability state ending means” in the present invention.

  When the lottery table corresponding to the gaming state is selected in this manner, it is determined whether or not the big hit lottery result is “big hit” by referring to the selected big hit lottery table based on the previously read big hit lottery random number ( FIG. 15 S3314). As described above, the high probability jackpot lottery table referred to in the high probability state has a slightly larger number of “big hit random numbers” than the low probability jackpot lottery table referred to when not in the high probability state. Since it is set, the lottery result of “big hit” is generated with a slightly higher probability in the high probability state than in the case of not being in the high probability state.

  And when the result of the jackpot lottery is determined to be a jackpot (S3316: yes), after reading the jackpot symbol determination random number (S3316), the process of determining the jackpot symbol by referring to the jackpot symbol determination table This is performed (S3318). Note that the process of determining whether or not a win is made is performed by executing a big win lottery of whether or not a big win has been won. Therefore, the CPU 201 mounted on the main control board 200 of the present embodiment that executes the big hit lottery process corresponds to the “win / fail determining means” in the present invention.

  FIG. 17 is an explanatory diagram illustrating a jackpot symbol determination table that is referred to for determining a jackpot symbol. As described above with reference to FIG. 7, in the present embodiment, six symbols are set as the jackpot symbol. Correspondingly, in the jackpot symbol determination table shown in FIG. 17, in correspondence with the jackpot symbol determination random number, stop symbols (jackpot symbols) of these six special symbols and information for identifying the stop symbols (stop) Symbol identification information) is set. Therefore, the big hit symbol can be determined by referring to the big hit symbol determination table from the big hit symbol determination random number read in S3316 (S3318). When the big hit symbol is determined as described above, the big hit variation pattern table is selected (S3320).

  FIG. 18 is an explanatory diagram illustrating a big hit variation pattern table. As shown in the drawing, in the jackpot variation pattern table, a plurality of types of variation patterns are set in association with random number values of variation pattern determination random numbers. Further, the variation pattern is associated with the variation time of the special symbol (hence, the time of the symbol variation effect performed by the effect symbol display device 27). The jackpot variation pattern table is a table that is referred to in order to determine the variation pattern of the special symbol until the special symbol is stopped and displayed with the jackpot symbol. Note that the special symbols are displayed in a variable manner by actually switching the eight types of display modes shown in FIG. 7 one after another, so the special symbol variation pattern is substantially different from the special symbols. Corresponds to the time to be displayed. However, as described above, in the pachinko machine 1 of the present embodiment, the special symbol variation display performed by the special symbol display device 28 and the variation display of the identification symbols 27a, 27b, and 27c performed by the production symbol display device 27 are the same. Since they are linked to each other, when the variation pattern of the special symbol is determined, the time during which the identification symbols 27a, 27b, 27c are displayed in a variable manner is determined. Then, as will be described later, the CPU 221 of the sub-control board 220 displays the contents of the symbol variation effect for variably displaying the identification symbols 27a, 27b, and 27c on the screen of the effect symbol display device 27 within the range of the variation display time. Will be determined.

  In the above, the case where the result of the big hit lottery is determined to be a big hit (S3314: yes) in the special figure variation display process shown in FIG. 15 has been described. (S3314: no), the following processing is performed. First, an off symbol determination random number is acquired (S3322). Subsequently, by referring to an out symbol determination table (not shown) in which an out symbol is preset with respect to the out symbol determination random number, an out symbol corresponding to the acquired out symbol determination random number is determined (S3324). Note that the big hit symbol determination random number acquired when the game ball is detected by the start port switch 17s of the start port 17 may also be used for determination of the off symbol. In addition, when one type of out symbol is used, the out symbol can be determined without using the out symbol determining random number.

  Once the off symbol has been determined as described above, the process of selecting the variation pattern table for determining the variation pattern is started in the same manner as when the jackpot symbol has been determined. Then, it is determined whether or not the function for reducing the fluctuation time is activated (S3328). This determination is made by confirming whether or not the fluctuation shortening flag is set to ON. The fluctuation shortening flag is a flag that is set to ON simultaneously with the above-described opening extension flag after the big hit game ends. As described above, when the release extension flag is set to ON (when the release time extension function is activated), game balls frequently enter the start port 17, and accordingly, the number of special figure reservations is limited to the upper limit. It is easy to reach the value. As explained with reference to FIG. 11, when the number of special figure holds reaches the upper limit, even if a game ball enters the starting port thereafter, the big hit lottery corresponding to the incoming ball is not performed (random number for lottery). The player feels useless even if he puts a game ball into the start opening. In order to prevent this, shorten the special symbol fluctuation time (activate the fluctuation reduction function) and digest many fluctuations in a short time. I try to decrease. As a result of the determination processing in S3328, if the fluctuation shortening flag is set to ON (S3328: yes), a later-described “out-of-shortening fluctuation pattern table” is selected to shorten the fluctuation time (S3330), and the fluctuation shortening flag is selected. Is set to OFF (S3328: no), a later-described “non-shortening deviation variation pattern table” is selected (S3332).

  FIG. 19 is an explanatory diagram illustrating a deviation variation pattern table. In the “out-of-shortening variation pattern table” shown in FIG. 19A, a plurality of variation patterns with relatively short variation times are set in association with random number values of variation pattern determination random numbers. Therefore, when the deviation variation pattern table is selected, the special symbol and the identification symbol are varied for a relatively short time. Among these variation patterns, a variation pattern without reach and a variation pattern with reach are set. On the other hand, a plurality of variation patterns whose variation times are relatively long are set in the “non-shortening deviation variation pattern table” shown in FIG. 19B. Similarly to the “offset variation pattern table”, a variation pattern without reach and a variation pattern with reach are set. Both of the big hit variation pattern table and the losing variation pattern table are stored in advance in the ROM 202 mounted on the main control board 200. Note that the variation pattern without reach and the variation pattern with reach may be set in different tables, and the table may be selected according to the presence or absence of reach.

  When the variation pattern table is selected as described above (S3320, S3330, S3332), a variation pattern determination random number is acquired (S3334 in FIG. 15). Subsequently, with reference to the selected variation pattern table, the variation pattern stored in association with the variation pattern determination random number is read out, and then this variation pattern is determined as the variation pattern of the special symbol (S3336). ). Subsequently, after the special symbol display device 28 starts to display the variation of the special symbol (S3338), "1" is subtracted from the number of special symbol hold (S3340) to convey that the special symbol hold number has decreased. The hold command is transmitted toward the sub-control board 220 (S3342). Then, after transmitting a command (variation start command) for designating the determined variation pattern or special symbol stop symbol to the sub-control board 220 (S3344), the special diagram variation display processing shown in FIG. 14 and FIG. Is finished, and the process returns to the game control process shown in FIG.

  The CPU 221 of the sub-control board 220 acquires information on the special symbol fluctuation pattern and the stop symbol based on the fluctuation start command output from the main control board 200 in this manner. And according to those information, after designating the content of the symbol variation effect performed by carrying out the variable display of the three identification symbols 27a, 27b, and 27c with the effect symbol display apparatus 27, a symbol variation effect is performed. As described above, during the opening extension period, the shortening and deviation variation pattern table is selected, so that the time of the symbol variation production becomes short and the production becomes monotonous, which may lead to a decrease in the player's gaming interest. . In the present embodiment, the game fun of the player during the open extension period is enhanced by the following ideas. The effect symbol display device 27 corresponds to the “symbol display device” in the present invention. In addition, the symbol (identification symbol) is stopped and displayed on the effect symbol display device 27 by performing the above-described processing. Therefore, the CPU 221 of the sub-control board 220 corresponds to “symbol display means” in the present invention.

  The detailed process performed in the special symbol game process when the special symbol is not variably displayed (that is, in the case of S324: no in FIG. 12) has been described above. On the other hand, when the special symbol game process of FIG. 12 is started while the special symbol is changing, it is determined that the special symbol is changing (S324: yes). This case corresponds to the case where the special symbol variation pattern and the stop symbol have already been determined and the special symbol variation has started. Therefore, it is determined whether or not the special symbol variation time has elapsed (S346). Since the variation time of the special symbol is determined in advance according to the variation pattern, it is possible to determine whether a predetermined variation time has elapsed by setting a timer at the same time as starting the variation of the special symbol. If the variation time has not yet elapsed (S346: no), the special symbol game process is terminated as it is, and the process returns to the game control process shown in FIG.

  On the other hand, when it is determined that the fluctuation time has elapsed (S346: yes), a command (design stop command) indicating that the special symbol is to be stopped is transmitted to the sub-control board 220 (S348). At the same time, the special symbol variably displayed on the special symbol display device 28 is stopped and displayed with the symbol set in advance (S350). Next, after setting the time for stopping and displaying the special symbol (stop display time for the special symbol) (S352), it is determined whether or not the set stop display time has elapsed (S354). If the stop display time has not elapsed (S354: no), the special symbol game process is terminated as it is, and the process returns to the game control process shown in FIG.

  On the other hand, when the special symbol stop display time has elapsed (S354: yes), it is determined whether or not the special symbol that is stopped and displayed is one of the big hit symbols shown in FIG. 7 (S356 in FIG. 13). ). If the symbol that has been stopped is a jackpot symbol (S356: yes), the jackpot flag indicating that the jackpot game is started is set to ON (S358). The big hit flag is a flag indicating that the big hit game is started, and a predetermined address of the RAM 203 mounted on the main control board 200 is assigned to the big hit flag. When the value of the predetermined address is set to “1”, the big hit flag is turned ON.

  Subsequently, after a command indicating that a big hit game is started (a big hit start command) is transmitted to the sub-control board 220 (S360), an extension extension number setting process is performed (S362). In the opening extension number setting process, as described in detail later, the above opening time extension is performed according to the time when the big hit game is started (according to the winning time for the big hit lottery that triggered the big hit game). A process of setting the number of games (number of fluctuations) for activating the function in an open extension counter described later is performed. By setting the number of games, the open time extension function operates until the number of games has elapsed since the end of the big hit game. When the opening extension number setting process is completed, it is determined whether or not the high probability flag is ON (S364). When the high probability flag is set to ON (S364: yes), it can be determined that the current gaming state is a high probability state. Therefore, the high probability flag is set to OFF (that is, the value of the high probability flag is changed from “1” to “0”), thereby terminating the high probability state (S366).

  Next, it is determined whether or not the release extension flag is set to ON (S368). If the release extension flag is set to ON (S368: yes), the extension extension is performed to stop the release time extension function. The flag is turned off (S370). Further, in the pachinko machine 1 according to the present embodiment, when the open time extension function is activated, the fluctuation shortening function also works. Therefore, when the release extension flag is turned OFF and the release time extension function is stopped (S370), the change shortening flag is turned OFF (S372) to stop the change shortening function, and then the special symbols shown in FIG. 12 and FIG. After exiting the game process, the process returns to the game control process of FIG. On the other hand, when the big hit symbol is stopped and displayed, neither the high probability flag nor the open / extended flag is set to ON (S364: no, S368: no), the game goes out of the special symbol game process as it is, and the game Return to control processing.

  The processing in the case where the special symbol stopped and displayed on the special symbol display device 28 is a jackpot symbol (S358: yes) has been described. However, when the symbol is not a jackpot symbol (in the case of a missed symbol) (S358) : No), the following processing is performed. First, it is determined whether or not the above-described release extension flag is set to ON (S374). If the release extension flag is OFF (S374: no), the special symbol game process is exited as it is, and the process returns to the game control process shown in FIG.

  On the other hand, when the release extension flag is ON (S374: yes), after subtracting “1” from the extension extension counter (S376), it is determined whether or not the extension extension counter has become “0”. (S378). Here, the release extension counter is a dedicated counter for counting the number of times the special symbol has been changed while the release extension flag is set to ON, and is set to a predetermined address in the RAM 203 of the main control board 200. ing. In the pachinko machine 1 according to the present embodiment, the release extension flag is set to ON after the big hit game is ended, and the number of games (the number of fluctuations) at which the release time extension function is activated is set to the release extension counter. The value set in the release extension counter (the number of games (the number of changes) in which the release time extension function operates) will be described in detail later.

  When it is determined in the process of S378 that the release extension counter has become “0” (S378: yes), an extension extension period end process is performed (S380). As will be described in detail later, in the opening extension period end process, various flag processes (open extension flag OFF setting, fluctuation shortening flag OFF setting, etc.) are performed in order to end the opening extension period. When the release extension period end process is completed, the special symbol game process is exited, and the process returns to the game control process of FIG. On the other hand, if the release extension counter is not yet "0" (S378: no), the release extension period continues, so the special symbol game process is exited with the release extension flag and the variable reduction flag set to ON. Returning to the game control process of FIG.

  As shown in FIG. 9, in the game control process, when returning from the special symbol game process, it is determined whether or not the big hit flag is set to ON (S390). As described above, the big hit flag is a flag that is set to ON when a special symbol is stopped and displayed as a big hit symbol. If the jackpot flag is set to ON (S390: yes), the CPU 201 mounted on the main control board 200 starts a jackpot game process described below (S400). On the other hand, if the big hit flag is not set to ON (S390: no), the big hit game process (S400) is skipped, the process returns to the top of the game control process, and the series of the above-described winning ball related process (S50) and the subsequent series. Repeat the process.

A-3-5. Jackpot game processing:
FIG. 20 is a flowchart showing the big hit game process. By executing such a big hit game process, a special game (so-called big hit game) is performed. Hereinafter, the jackpot game process will be described with reference to FIG. 20, but as a preparation, the contents of a game called a jackpot game will be briefly described.

  As described above with reference to FIG. 2, a special winning opening 31d is provided below the game board, and the special winning opening 31d is closed in a normal gaming state. However, when the big hit game is started, the big winning opening 31d is opened. Since the special winning opening 31d is greatly opened as compared to other winning openings, when the special winning opening 31d is in an open state, the game ball enters with a high probability. The opened big winning opening 31d is once closed when a predetermined opening time elapses or a predetermined number of game balls enter, but is again opened when a predetermined closing time elapses. In addition, a game from when the special winning opening 31d is opened to when it is closed is called “round game (or simply round)”. If such a round game is repeated and a predetermined number of round games are consumed, the big hit game ends. Hereinafter, the jackpot game process performed by the CPU 201 of the main control board 200 in order to execute the jackpot game described above will be described with reference to FIG.

  When starting the big hit game process (S400), the CPU 201 of the main control board 200 first determines whether or not the big winning opening 31d is open (S402). The big prize opening 31d is closed in a normal gaming state, and therefore, the big prize opening 31d is in a closed state immediately after the start of the big hit game. Accordingly, it is determined that the special winning opening 31d is not being opened (S402: no), and it is determined whether or not the number of opening of the special winning opening 31d (that is, the number of rounds) has reached a predetermined number (S404). As described above, during the big hit game, the big winning opening 31d is opened and a predetermined number of round games are repeated. Corresponding to this, when the special winning opening 31d is closed (S402: no), it is determined whether or not the number of opening of the special winning opening 31d (number of round games) has reached a predetermined number ( S404).

  As a matter of course, immediately after the big hit game is started, the number of times of opening of the big prize opening 31d has not reached the predetermined number (S404: no), so it is determined whether or not the closing time of the big prize opening 31d has elapsed. (S406). The closing time of the special winning opening 31d is a time during which the special winning opening 31d is in a closed state between rounds. Immediately after the big hit game is started, the big prize opening 31d is in a closed state, so it is naturally determined that the closing time of the big prize opening 31d has passed (S406: yes), and the big prize opening 31d is opened. The game is released and a new round game is started (S408). Then, after transmitting a command (round start command) for designating the start of a new round game to the sub-control board 220 (S410), the jackpot game process shown in FIG. 20 is temporarily ended, and the game shown in FIG. Return to control processing.

  When the CPU 201 of the main control board 200 returns to the game control process, as shown in FIG. 9, after performing a series of various processes after the prize ball related process (S50), the big hit game process (S400) is started again. . As described above, the time required for the CPU 201 of the main control board 200 to execute the game control process shown in FIG. 9 once is about 4 msec. Accordingly, the big hit game process shown in FIG. 20 is also executed about every 4 msec. Then, when the special game is started and the big hit game process of FIG. 20 is executed for the first time, the big winning opening 31d is opened in S408 as described above, and the process is ended as it is. When performing the process of the round, it is determined in S402 that the special winning opening 31d is open (S402: yes).

  Next, it is determined whether or not the opening time of the special winning opening 31d has reached a predetermined time (S412). As described above, in the big hit game, the big winning opening 31d is opened, but is closed when the opening time reaches a predetermined time or when a predetermined number of game balls enter the big winning opening 31d. In response to this, in S412, it is determined whether or not the opening time of the special winning opening 31d has reached a predetermined time. Then, if the opening time has reached the predetermined time (S412: yes), after closing the special winning opening 31d (S416), the big hit game process shown in FIG. 20 is exited, and the game control process shown in FIG. 9 is resumed. To do. On the other hand, if the opening time has not reached the predetermined time (S412: no), it is determined whether or not the number of game balls that have entered the special winning opening 31d has reached the specified number (S414). When the number of game balls reaches the specified number (S414: yes), the special winning opening 31d is closed (S416). On the other hand, when the prescribed number has not been reached (S414: no), the opening time of the special winning opening 31d has not yet reached the predetermined time, and the number of game balls that have entered the special winning opening 31d is also the prescribed number. Therefore, the big winning game process shown in FIG. 20 is exited while the special winning opening 31d is opened, and the process returns to the game control process shown in FIG.

  While the game control process of FIG. 9 is repeatedly executed, does the opening time of the special winning opening 31d reach a predetermined time (S412: yes), or a prescribed number of gaming balls enter the special winning opening 31d? A ball is formed (S414: yes), and the special winning opening 31d is closed (S416). Thus, one round game is completed. Then, when the big hit game process is executed next, it is determined in S402 that the big winning opening 31d is closed (S402: no), and it is determined whether or not the predetermined number of round games are ended (S404). If the round game is not finished (S404: no), after confirming that the closing time of the big prize opening has reached the predetermined time (S406: yes), the big prize opening 31d is opened again and a new round is made. After the game is started (S408), a round start command is transmitted toward the sub-control board 220 (S410). On the other hand, if it is determined in S404 that the predetermined number of round games have ended (S404: yes), the big hit flag is changed to OFF to end the big hit game (S418). Note that the big hit game is executed by performing the above-described processing. Therefore, the CPU 201 mounted on the main control board 200 that performs the processing corresponds to the “winning game execution means” in the present invention. When the big hit game is terminated as described above, an opening extension period start process is performed (S420). As will be described in detail later in the opening extension period start processing, processing of various flags (high probability flag ON setting, fluctuation shortening flag ON setting, opening extension flag ON setting, etc.), etc. to start the opening extension period, etc. (S420). When the opening extension period start process is completed, a jackpot end command is output to the CPU 221 of the sub-control board 220 (S422), the jackpot game process is terminated, and the process returns to the game control process of FIG. Note that the process of shifting the gaming state to the high probability state is executed by performing a process of setting the high probability flag to ON. Therefore, the CPU 201 mounted on the main control board 200 can also be referred to as “high probability state transition means”. In addition, by operating the opening extension function, it is easy to enter the game ball into the starting port. Therefore, the CPU 201 mounted on the main control board 200 can also be referred to as “entrance easy means”.

A-4. Processing to set the length of the open extension period:
Next, processing for setting the length of the opening extension period (number of games for operating the opening extension function) (start processing of the extension extension period, processing at the time of falling, end processing of the extension extension period, game of the opening extension period) The number setting process) will be described in detail. First, a process for starting the extended extension period (open extended period start process) in this process will be described.

A-4-1. Opening extension period start processing:
FIG. 21 is a flowchart showing the opening extension period start process. The opening extension period start process is executed by the CPU 201 mounted on the main control board 200 after the jackpot game is ended in the jackpot game process shown in FIG. 20 as described above (S420 in FIG. 20). When the opening extension period start processing is started, first, processing for setting the high probability flag to ON is performed in order to shift to the high probability state after the end of jackpot (S4200). Subsequently, the open extension flag is set to ON to activate the open extension function at the same time as the transition to the high probability state (S4202). Then, the fluctuation shortening flag is also set to ON (S4204). As a result, a variation pattern with a shortening is selected in the next special diagram variation display processing (see S3328 to S3330 in FIG. 15), and the opening time of the start port 17 is extended in the next normal symbol game processing (in FIG. 10). (See S230 to S232).

  Next, the disadvantageous hit period flag is set to ON (S4206). Here, in the first embodiment, the opening extension period starts simultaneously with the start of the opening extension period and ends by winning the falling lottery, and the opening extension period starts by winning the falling lottery. It is divided into an advantageous jackpot period that ends simultaneously with the end of the extension period. The disadvantageous hit period flag is a flag for the CPU 201 mounted on the main control board 200 to grasp that the current period is the disadvantageous hit period, and is set to ON during the disadvantageous hit period. When the disadvantageous hit period flag is set to ON, a command to start the disadvantageous hit period (unfavorable hit period start command) is output to the sub-control board 220 (S4208), and the opening extension period start process is terminated. Returning to the big hit game process of FIG. The characteristics of the disadvantageous big hit period and the advantageous big hit period will be described later.

  In the above, it has been described that the disadvantageous big hit flag is set to ON to start the disadvantageous big hit period when the extended extension period is started at the end of the big hit. Below, the process in the case of winning the falling lottery during the open extension period (unfavorable hitting period) started as described above will be described.

A-4-2. Falling processing:
FIG. 22 is a flowchart showing a process (falling process) when winning the falling lottery. The process at the time of falling is executed when the CPU 201 mounted on the main control board 200 wins the falling lottery in the special figure variation display process shown in FIG. 14 as described above (S3308 in FIG. 14). When the process at the time of falling starts, first, the high probability flag is set to OFF in order to shift the gaming state to the low probability state (S3500). Thus, in the next special figure variation display process, it is determined that the high probability flag is OFF (S3302: no in FIG. 14), and the low probability big hit lottery table is selected (S3312).

  When the high probability flag is set to OFF (S3500), it is next determined whether or not it is during the open extension period (whether or not the open extension flag is ON) (S3502). If it is determined that the current period is the opening extension period (S3502: yes), it means that the winning lottery was won during the opening extension period. Therefore, the disadvantageous big hit period flag set to ON from the start of the extended extension period is set to OFF (S3504), and the advantageous big hit period flag is set to ON (S3506). The advantageous jackpot period flag is a flag for the CPU 201 mounted on the main control board 200 to grasp that the current period is the advantageous jackpot period, and is set to ON during the advantageous jackpot period. Then, after outputting a command to start the advantageous big hit period (advantageous big hit period start command) to the sub-control board 220 (S3508), the process at the time of falling ends, and the special figure variation display process of FIG. Return. On the other hand, when it is determined that it is not the open extension period (the open extension flag is set to OFF) (S3502: no), neither the disadvantageous big hit period nor the advantageous big hit period is present, so the disadvantageous big hit period flag is also the advantageous big hit period flag. Without the operation, the process at the time of falling is ended as it is, and the process returns to the special figure fluctuation display process of FIG. It should be noted that the disadvantageous hit period flag and the advantageous hit period flag (hereinafter also collectively referred to as “period flags”) are assigned predetermined addresses in the RAM 203 of the main control board 200, respectively.

  As mentioned above, if the winning lottery is won before the extended extension period ends, the high probability flag is set to OFF to shift to the low probability state, and at the same time, the disadvantageous hit period flag is set to OFF to win the big hit By setting the period flag to ON, processing for switching from the disadvantageous big hit period to the advantageous big hit period is performed. On the other hand, if the winning lottery is not won before the extended extension period ends, the advantageous big hit period flag is not set to ON and the advantageous big hit period is not switched. In the present embodiment, by performing the above processing, one of the easy-to-enter states (opening extension period) (the state before falling) is determined as an advantageous period (an advantageous big hit period). Therefore, the CPU 201 mounted on the main control board 200 corresponds to the “advantageous period determining means” in the present invention.

  As described above, it has been explained that when the falling lottery is won during the opening extension period, the disadvantageous big hit period ends and the advantageous big hit period starts. Below, the process for ending an open extension period is demonstrated.

A-4-3. Opening extension period termination processing:
FIG. 23 is a flowchart showing the opening extension period end processing. The opening extension period ending process is performed when the value of the opening extension counter becomes “0” in the special symbol game process shown in FIGS. 12 and 13 by the CPU 201 mounted on the main control board 200 as described above (opening). This is executed when the number of games in which the extension function is activated reaches the set number of times (S380 in FIG. 13). When the opening extension period end process is started, first, the opening extension flag is turned OFF to stop the opening extension function (S3800). Subsequently, after the fluctuation reduction flag is also set to OFF in order to stop the fluctuation reduction function (S3802), the disadvantageous hit period flag and the advantageous hit period flag (hereinafter also collectively referred to as “period flag”) are turned ON. The set flag is set to OFF (S3804). That is, at the end of the opening extension period, as described above, if the falling lottery is not won during the opening extension period, the disadvantageous hit period flag is set to ON, and the falling lottery is won during the opening extension period. If this is the case, the advantageous big hit period flag is set to ON. Regardless of the advantageous jackpot period or the unfavorable jackpot period immediately before the end of the opening extension period, the period flag that is set to ON is set to OFF because it is terminated with the end of the opening extension period. Then, after transmitting a command indicating that the extended extension period has ended (open extended period end command) to the sub-control board 220 (S3806), the extended extended period end process is ended, and the special symbol of FIG. Return to game processing.

A-4-3. Opening extension number setting process:
As described above, when the jackpot game ends, the disadvantageous jackpot period starts with the start of the extended extension period. Then, if the falling lottery is won during the opening extension period, the winning lottery period is switched to. If the falling lottery is not won during the opening extension period, the disadvantageous big hit period is continued. In addition, when the open extension period ends, the period ends in any of the advantageous jackpot period and the disadvantageous jackpot period. In this embodiment, among the disadvantageous jackpot period, the advantageous jackpot period, and other periods (periods other than the opening extension period), the jackpot game corresponding to the corresponding selection is determined depending on which period the jackpot lottery is won. The length of the open extension period after completion (the number of fluctuations that activates the open extension function) is set differently. Hereinafter, a process for setting the length of the open extension period (open extension number setting process) will be described.

  FIG. 24 is a flowchart showing the opening extension number setting process. The opening extension number setting process is executed by the CPU 201 mounted on the main control board 200 when the special symbol stopped and displayed in the special symbol game process shown in FIG. 12 and FIG. (S362). When the opening extension number setting process is started, first, it is determined whether or not the disadvantageous hit period flag is set to ON (S3620). That is, it is determined whether or not the winning of the current big hit lottery (S3314 in FIG. 15) has occurred during the disadvantageous big hit period. As a result, when the disadvantageous hit period flag is set to ON (S3620: yes), “10” is set to the open extension counter (S3622). When a numerical value is set as the value of the open extension counter in this way, it becomes possible to operate the open time extension function until the set number of games (here, 10 times) has elapsed (S374 to S380 in FIG. 13). reference).

  On the other hand, when the disadvantageous hit period flag is set to OFF (S3620: no), it is determined whether or not the advantageous hit period flag is set to ON (S3624). That is, it is determined whether or not the winning of the current big hit lottery occurred during the advantageous big hit period. As a result, when the advantageous big hit period flag is set to ON (S3624: yes), the open extension counter is set to “100” (S3626). On the other hand, when the advantageous big hit period flag is also set to OFF (that is, when the win for the current big hit lottery is neither an unfavorable big hit period nor an advantageous big hit period) (S3624: no), the open extension counter is set to “50”. Is set (S3628). Thus, if a numerical value is set in the opening extension counter corresponding to the winning time for the big hit lottery, the extended extended period also ends with the start of the big hit game, so the disadvantageous big hit period flag and the advantageous big hit period flag are turned OFF. (S3630). Of course, since one or both of the period flags are already set to OFF, the process of setting the period flags to OFF again may not be performed.

  As described above, in the opening extension number setting process, if the winning for the big hit lottery occurs during the disadvantageous big hit period, the number of games for which the open time extension function is activated is set to “10” and occurs during the advantageous big hit period. In such a case, the number of games is set to “100” times, and when it occurs in another period (when it occurs outside the extended extension period), the number of games is set to “50” times. In other words, when the big hit lottery is won during the disadvantageous big hit period, the number of games in which the opening time extension function is activated is “10”, and the big hit lottery is performed during the normal period (a period where neither the advantageous big hit period nor the disadvantageous big hit period). The big hit game is started which is more disadvantageous than the case where the number of games is won (the number of games is “50”) (the number of games where the opening time extension function follows is small). In addition, when the big hit lottery is won during the advantageous big hit period, the number of games in which the opening time extension function operates is “100”, which is more advantageous than when the big hit lottery is won during the normal period (following open time extension) A big hit game is started).

  The CPU 201 mounted on the main control board 200 advances the game of the pachinko machine 1 by repeatedly performing the game control process as described above. Further, the CPU 221 of the sub control board 220 grasps the state of the game based on various commands transmitted from the main control board 200 in order to produce the game performed in this way. Various effects using sound effects and lamps. Below, the process for performing the effect which alert | reports a disadvantageous big hit period and an advantageous big hit period with respect to a player also in such an effect is demonstrated.

A-5. Period notification effect processing:
FIG. 25 is a flowchart showing a period notification effect process performed in the pachinko machine 1 of the first embodiment. This game effect process is a process executed by the CPU 221 mounted on the sub-control board 220.

  As shown in FIG. 25, in the period notification effect process (S500), first, it is determined whether or not a disadvantageous big hit period start command (or big hit end command) has been received from the main control board 200 (S502). As a result, if a disadvantageous hit period start command has been received (S502: yes), an effect of informing the disadvantageous hit period is started (S504). In the present embodiment, as an effect of notifying the disadvantageous hit period, “adverse effect mode display indicating that the game is progressing during the disadvantageous hit period” is performed on the display screen of the effect symbol display device. If an unfavorable jackpot period start command has not been received (S502: no), it is next determined whether an advantageous jackpot period start command has been received (S506). As described above, in the first embodiment, the advantageous jackpot period is always started following the disadvantageous jackpot period. Therefore, if the advantageous jackpot period start command is received (S506: yes), the disadvantageous jackpot period is notified. After ending (after ending the disadvantageous effect mode display), an effect to notify the advantageous big hit period is started (S508). In this embodiment, as an effect for notifying the advantageous jackpot period, “advantageous effect mode display indicating that the game is progressing in the advantageous jackpot period” is performed on the display screen of the effect symbol display device.

  If an advantageous big hit period start command has not been received (S506: no), it is next determined whether or not an open extension period end command has been received (S510). As described above, the disadvantageous jackpot period and the advantageous jackpot period are periods during the open extension period, and any period ends at the same time as the end of the open extension period. Therefore, when the opening extension period end command is received (S510: yes), the notification effect of the disadvantageous hit period or the advantageous hit period that is being executed at that time is ended (S512).

  If no open extension period end command has been received (S510: no), it is determined whether or not a jackpot start command has been received (S514). As described above, the jackpot game can be started during the extended extension period (even a disadvantageous jackpot period or an advantageous jackpot period) or during other periods. Therefore, receiving the jackpot start command may be during the stage of reporting the disadvantageous jackpot period or the advantageous jackpot period, or in other cases, so whether or not the stage is being broadcasted. Judgment is made (S516). And when it is during the production | presentation which alert | reports any period (S516: yes), this production | generation is complete | finished (S518) and a period notification production | presentation process is complete | finished. When it is determined that the jackpot start command has not been received (S514: no), and when no effect for notifying any period is performed (S516: no), the period notification effect process is terminated.

A-6. Gameability obtained by the first embodiment:
FIG. 26 mainly shows from the start to the end of the unfavorable jackpot period (the period in which the unfavorable jackpot period flag is set to ON) and the advantageous jackpot period (the period in which the advantageous jackpot period flag is set to ON). It is explanatory drawing which illustrated a mode. In FIG. 26, the horizontal axis indicates the passage of time. As shown in FIG. 26, the disadvantageous hit period is started simultaneously with the opening extension period being started (the disadvantageous hit period flag is ON). As described above, the unfavorable jackpot period is a period for winning an unfavorable jackpot game. In this embodiment, after the jackpot game corresponding to the selection is completed, an open extension period for 10 games is given. Also, as shown in FIG. 26 (a), if the falling lottery is won during the unfavorable big hit period (when the high probability state is set to OFF and the low probability state is entered), the advantageous big hit period (indicated by hatching in the figure) Period) is started (the advantageous big hit period flag is ON). As described above, the advantageous jackpot period is a period for winning an advantageous jackpot game. In this embodiment, after the jackpot game corresponding to the selection is completed, an opening extension period for 100 games is given.

  As shown in FIG. 26 (a), the disadvantageous big hit period is from the start of the extended extension period until winning the falling lottery. The advantageous big hit period ends after the winning lottery is won. Up to. Since the length of the open extension period is predetermined (here, 50 times), the lengths of the disadvantageous hit period and the advantageous hit period change depending on the timing of winning the falling lottery. In particular, as shown in FIG. 26 (b), when the falling lottery is not won during the extended extension period, the advantageous big hit period is not started, and the normal big hit game is won (the big win lottery is won). Then, after the jackpot game corresponding to the corresponding selection is completed, a period in which 50 open extension periods are granted is started.

  In this way, in this embodiment, during the operation of the opening extension function after the end of the big hit game, rather than immediately executing the next big hit game, in the “advantageous big hit period” after the winning in the falling lottery The person who executes the big hit game is to give the player a big privilege (granting the opening extension period 100 times). In this way, the following unique game characteristics can be realized by utilizing the winning of the falling lottery, which has been an opportunity for a situation unfavorable to the player, as an opportunity to an advantageous situation for the player. .

  In other words, in this embodiment, the game period (unfavorable big hit period) from the end of the big hit game until winning the falling lottery is the benefit (open extension period) granted after the big hit game is executed. It becomes small (the open extension period after the big hit game is shortened). Of course, if the jackpot game is executed, the player can receive a predetermined amount of balls, so that the player's gaming interest will not be significantly reduced by the jackpot game execution. However, in order to obtain a big ball in a series of subsequent games as well as one big hit game, it is necessary to execute a big hit game with an advantageous big hit period. The game progresses with the player expecting to establish a condition for shifting to the big hit period (winning of the falling lottery) than the winning of the lottery. Further, the staying period of the advantageous jackpot period changes depending on the winning timing of the falling lottery during the disadvantageous jackpot period. For this reason, in the disadvantageous hit period, the player expects to win the falling lottery as soon as possible, and the game proceeds. Then, if the winning lottery is won, the player will expect to win the jackpot lottery by the end of the advantageous jackpot period, and the game will proceed. As described above, in the pachinko machine of this embodiment, the player expects the “game progress mode in which the jackpot game is executed after winning the falling lottery in the extended extension period after the jackpot game ends” Can realize the innovative gameability that a player expects in the “Lottery of Lottery”, and the game during the “extension period that tends to be monotonous” will be sharpened, and it will be possible to greatly excite the player's gaming fun .

  In the above-described embodiment, after the jackpot game executed in the disadvantageous jackpot period is ended, the extension extension period for 10 games is given, but the jackpot game executed in the disadvantageous bonus period is finished. In the later extended extension period, the number of times given during normal times is set to 0, and the same game characteristics can be ensured even if the open extended function is not activated. In addition, the CPU 201 mounted on the main control board 200 performs the processing as described above, so that the state when winning the big hit lottery is a high probability state of the open extension period and a low probability state of the open extension period. Depending on the state, the progress control of the game is performed so that the magnitude of the profit (the length of the open extension period) given to the player in accordance with the execution of the jackpot game is different. Therefore, the CPU 201 mounted on the main control board 200 corresponds to the “game progress control means” in the present invention.

B. Second embodiment:
In the first embodiment described above, as shown in FIG. 17, six types of special symbols are assigned almost the same number of jackpot symbol determination random numbers, so when winning the jackpot lottery, The special symbols (and the identification symbols “1” to “6” that are stopped and displayed so as to be three on the effect symbol display device 27 corresponding to each special symbol) are stopped and displayed with the same probability without bias. On the other hand, the probability that each special symbol is stopped and displayed may be biased.

  FIG. 27 is an explanatory diagram illustrating a jackpot symbol determination table referred to for determining the jackpot symbol of the second embodiment (corresponding to FIG. 17 of the first embodiment). As shown in FIG. 27, a special symbol “TZ001” in the range of “0 to 75” is set in the special symbol “TZ001” in the uppermost stage, and the special symbol “TZ001” is stopped and displayed when the big hit lottery is won. Probability is about 30 percent. In addition, the special symbol “TZ002” has a big hit symbol determination random number in the range of “76 to 151”, and the probability that the special symbol “TZ002” is stopped and displayed when the big hit lottery is won is about 30%. It has become. Hereinafter, the special symbols “TZ003” and “TZ004” have a probability of stopping about 15%, and the special symbols “TZ005” and “TZ006” are about 5%. A jackpot symbol determination random number is set for the symbol. The special symbols “TZ001” to “TZ006” respectively correspond to the identification symbols “1” to “6” that are stopped and displayed so as to be aligned on the effect symbol display device 27. That is, when the special symbol is determined to be stopped and displayed in the big hit lottery (S3320 in FIG. 15), the stop symbol identification information “TZ001” to “TZ006” is transferred from the main control board 200 to the sub-control board. Output to 220. Then, the CPU 221 of the sub-control board 220 stops and displays on the effect symbol display device 27 so that three identification symbols “1” to “6” corresponding to the stop symbol identification information received from the main control board 200 are arranged. Therefore, when winning the big hit lottery, the identification symbols “1” and “2” are stopped and displayed on the effect symbol display device 27 with a probability of about 30%, respectively, like the special symbols “TZ001” and “TZ002”. The identification symbols “3” and “4” are about 15%, respectively, like the special symbols “TZ003” and “TZ004”, and the identification symbols “5” and “6” are the same as the special symbols “TZ005” and “TZ006”, respectively. The effect symbol display device 27 is stopped and displayed with a probability of about 5%. Thereby, when winning the big hit lottery, the identification symbols “1” and “2” are relatively easily stopped and displayed, and the identification symbols “5” and “6” are relatively difficult to be stopped and displayed.

  In the first embodiment, no particular mention was made of the number of rounds of the big hit game. However, the number of rounds in the jackpot game may be varied depending on the special symbol (identification symbol) that is stopped and displayed when the jackpot lottery is won.

  FIG. 28 is a jackpot game round number setting table in which the number of rounds of the jackpot game is set for each special symbol. As shown in FIG. 28, “4 rounds” are set for the special symbols “TZ001” to “TZ004”, and “7 rounds” are set for the special symbols “TZ005” and “TZ006”. Yes. For determining the number of rounds, after the jackpot symbol is stopped and displayed (corresponding to S356: yes in FIG. 13 of the first embodiment), the special symbol stopped and displayed this time is grasped, and the number of rounds corresponding to the special symbol is determined. This is done by reading from the jackpot game round number setting table and setting it as the number of rounds of the current jackpot game. As described above, the identification symbol to be stopped and displayed on the effect symbol display device 27 corresponds to the special symbol, so that the player confirms the identification symbol at the time of winning the big hit lottery, thereby confirming the subsequent big hit game. The number of rounds (4 rounds if the identification symbol is “1” to “4”, 7 rounds if the identification symbol is “5” or “6”) can be recognized, and many rounds are set. The game is advanced while expecting the identification symbols “5” and “6” to be stopped and displayed.

  In the first example, no particular mention was made of the probability of winning the falling lottery. However, the probability of falling from the high probability state after the big hit game (probability of shifting to the low probability state) may be determined according to a special symbol (identification symbol) that is stopped and displayed when winning the big hit lottery.

  FIG. 29 is a falling lottery probability setting table in which the probability of winning the falling lottery is set for each special symbol. As shown in FIG. 29, the special symbol “TZ001” and “TZ002” are set to “10/100” as the winning probability for the falling lottery, and the special symbol “TZ003” to the falling lottery. “20/100” is set as the winning probability. Hereinafter, “5/100” is set for the special symbol “TZ004”, “1/100” is set for “TZ005”, and “99/100” is set for “TZ006”. As can be seen from these probabilities, when the special symbol “TZ005” (identification symbol “5”) is stopped, it is most difficult to win the falling lottery, while the special symbol “TZ006” (identification symbol “6”). ) Is displayed as a stop, it is easier to win the falling lottery. The probability of the falling lottery is determined by grasping the special symbol stopped and displayed this time before performing the processing at the time of falling (corresponding to S3308 in FIG. 14 of the first embodiment), and calculating the falling probability corresponding to the special symbol. This is done by reading from the falling lottery probability setting table and setting it as the probability of winning the falling lottery this time. In the fall lottery probability setting table, a plurality of establishment probability (probability of winning the fall lottery) of specific conditions that are satisfied when the high probability state is terminated are set. Therefore, the “falling lottery probability setting table” can also be referred to as a plurality of “advantageous disadvantage setting patterns”. In addition, the CPU 201 mounted on the main control board 200 performs the above-described processing, thereby determining the possibility of establishment of the specific condition (winning probability for falling lottery) from a plurality of types. Therefore, the CPU 201 mounted on the main control board 200 corresponds to “end possibility determination means” in the present invention.

  Further, in the first embodiment, the game period before the falling lottery win is set as an unfavorable big hit period and the game period after the drop lottery win is set in advance as an advantageous big hit period in the extended extension period after the end of the big hit game. That is, in the process for starting the open extension period (open extension period start process shown in FIG. 21), the disadvantageous hit period flag is always set to ON (S4206 in FIG. 21). On the other hand, depending on the special symbol (identification symbol) that is stopped and displayed when the big hit game is started, it is determined whether the game period before winning the falling lottery is the disadvantageous big hit period or the advantageous big hit period. May be.

B-1. Opening extension period start processing of the second embodiment:
FIG. 30 is a flowchart showing the open extension period start process of the second embodiment. The opening extension period start process of the second embodiment is performed at the end of the big hit game (S420 in FIG. 20), similarly to the opening extension period start process of the first embodiment. When the opening extension period start process of the second embodiment is started, first, similarly to the first embodiment, a high probability flag, an opening extension flag, and a variable shortening flag are set to start the opening extension period at the same time as shifting to the high probability state. Is set to ON (S600, S602, S604). Next, the winning stop symbol of the special symbol that triggers the start of the big hit game that ends this time is grasped (S606). Then, based on the recognized special symbol hit stop symbol and an advantageous / disadvantage setting table described later, it is determined which of the disadvantageous hit period or the advantageous hit period is started first (S608).

  FIG. 31 is an advantageous / disadvantage setting table in which a disadvantageous big hit period or an advantageous big hit period is set as the period to start first for each special symbol hit stop symbol. As shown in FIG. 31, when the special symbols stopped and displayed when starting the big hit game are “TZ001”, “TZ003”, “TZ005”, the game starts from the advantageous big hit period, “TZ002”, “ In the case of “TZ004” and “TZ006”, it is set to start from the disadvantageous hit period. In the process of S608, the unfavorable big hit period or the advantageous big hit period corresponding to the special symbol hit stop pattern grasped in the process of S606 is read from the advantageous unfavorable setting table and grasped as a period to be started first. If the period to be started first is grasped, it is determined whether or not it is a disadvantageous hit period (S610). As a result, if it is determined that it is a disadvantageous hit period (S610: yes), in order to start the disadvantageous hit period, the disadvantageous hit period flag is set to ON (S612), and a command to start the disadvantageous hit period is started. After outputting (unfavorable hit period start command) to the sub-control board 220 (S614), the open extension period start process of the second embodiment is terminated. On the other hand, if it is determined in the processing of S610 that the advantageous big hit period is in effect (S610: no), the advantageous big hit period flag is set to ON to start the advantageous big hit period (S616), and the advantageous big hit period is started. After outputting a command (advantageous big hit period start command) to the sub-control board 220 (S618), the open extension period start process of the second embodiment is terminated. In the advantageous / unfavorable setting table, the state in which the high probability state and the easy entry state have occurred (the period before the fall in the opening extension period) is set as the advantageous state (advantageous hit period) or the disadvantageous state (unfavorable hit period) Is set multiple times. Therefore, the falling lottery probability setting table can be said to be a plurality of “advantageous disadvantage setting patterns”.

  As described above, in the opening extension period start process of the second embodiment, when the special symbol that is stopped and displayed when the big hit game is started is “TZ001”, “TZ003”, “TZ005”, an advantageous big hit period In the case of “TZ002”, “TZ004”, and “TZ006”, the process for starting from the advantageous big hit period is performed. As described above, the identification symbol to be stopped and displayed on the effect symbol display device 27 corresponds to the special symbol, so that the player can confirm the identification symbol when winning the big hit lottery, It can be recognized whether an unfavorable jackpot period is started or an advantageous jackpot period is started.

  Further, in the first embodiment, if the winning lottery is won during the opening extension period, the disadvantageous big hit period always ends and the advantageous big hit period starts. If it is during the period, the disadvantageous big hit period flag may be set to OFF and the advantageous big hit period flag may be set to ON (S3502 to S3506 in FIG. 22). However, in the second embodiment, as described above, before the falling lottery winning during the opening extension period is an unfavorable big hit period or an advantageous big hit period, immediately before winning the falling lottery (before the falling lottery win) It is necessary to set a period after winning the falling lottery after grasping the period.

B-2. Falling process of the second embodiment:
FIG. 32 is a flowchart showing the fall processing of the second embodiment. When the fall processing of the second embodiment is started, first, similarly to the first embodiment, the high probability flag is set to OFF in order to shift to the low probability state (S700). Next, it is determined whether or not the disadvantageous hit period flag is set to ON (S702). That is, it is determined whether or not the present is in the disadvantageous hit period. As a result, if the current time is in the disadvantageous bonus period (S702: yes), the disadvantageous bonus period flag set to ON from the start of the extended extension period is set to end the disadvantageous bonus period and start the advantageous bonus period. It is set to OFF (S704), and the advantageous big hit period flag is set to ON (S706). Then, after outputting a command to start an advantageous jackpot period (advantageous jackpot start command) to the sub-control board 220 (S708), the fall processing of the second embodiment is terminated. On the other hand, if it is determined in the processing of S702 that it is not an unfavorable big hit period (S702: no), this time, whether or not the advantageous big hit period flag is set to ON, that is, whether or not the current big hit period is set. Is determined (S710). As a result, when the current big hit period is in effect (S702: yes), the big hit period flag set to ON from the start of the extended extension period is set to end the big hit period and start the big hit period. It is set to OFF (S712), and the disadvantageous hit period flag is set to ON (S714). Then, after outputting a command to start the disadvantageous hit period (unfavorable hit period start command) to the sub-control board 220 (S716), the fall processing of the second embodiment is terminated. Note that if there is neither an unfavorable hit period nor an advantageous hit period (S702: no, S710: no), the process at the time of falling ends without operating the unfavorable hit period flag and the advantageous hit period flag.

  As described above, in the process at the time of falling in the second embodiment, when there is an unfavorable hit period at the time of falling, the process for ending the unfavorable hit period and starting the advantageous hit period is the same as in the first embodiment. If it is in the advantageous jackpot period when it falls, a process for ending the advantageous jackpot period and starting the disadvantageous jackpot period is performed. Therefore, by performing the opening extension period start process (FIG. 30) and the fall process (FIG. 32) of the second embodiment, the special symbols that are stopped and displayed when the big hit game is started are "TZ001" and "TZ003". , “TZ005” (identification symbol is “1”, “3”, “5”), the extended jackpot period starts at the same time as the opening extension period starts, and the winning lottery is won during the advantageous jackpot period If this happens, the disadvantageous bonus period will begin. In addition, when the special symbols stopped and displayed when the big hit game is started are “TZ002”, “TZ004”, “TZ006” (identification symbols “2”, “4”, “6”), As in the first embodiment, the disadvantageous bonus period starts at the same time as the opening extension period starts, and when the falling lottery is won during the disadvantageous bonus period, the advantageous bonus period is started.

  In the first embodiment, in the opening extension number setting process shown in FIG. 24, the value set in the opening extension counter (the number of games for operating the opening extension function) is the period of winning the big hit lottery (unfavorable big hit period, It has been described that a certain value (10 times, 100 times, 50 times) is set according to the advantageous jackpot period or the period other than the extended extension period. On the other hand, after winning the jackpot lottery for the first time, the jackpot lottery will continue to be won before the extended extension period (unfavorable jackpot period or advantageous jackpot period) after the jackpot game ends (hereinafter referred to as “Big Jack (It is also expressed as “continuous”), and the jackpot game becomes more advantageous (here, the opening extension period after the jackpot game becomes longer in stages (the number of games for operating the opening extension function increases) )). Hereinafter, an example will be described.

B-3. Opening extension number setting process of the second embodiment:
FIG. 33 is a flowchart showing the opening extension number setting process of the second embodiment. When the opening extension number setting process of the second embodiment is started, it is first determined whether or not the opening extension flag is set to ON (S800). As a result, if the release extension flag is not set to ON (if it is not the release extension period) (S800: no), the value of the extended game counter is set to “1” (S802). This consecutive resort counter is a counter for counting the number of consecutive jackpot lottery wins during the opening extension period (the number of consecutive consecutive jackpots (spanning)). In the process of S802, when winning the big hit lottery other than the extended extension period, it means that the big hit lottery was won first (so-called first win) (because it was not a continuous play), Set the value to “1”. The area of the extended counter is secured in the RAM 203 mounted on the main control board 200. When the value of the consecutive house counter is set to “1”, the value of the fluctuation shortening counter is set to “20”, and the opening extension number setting process of the second embodiment is completed. As described above, if the jackpot lottery is won during a period other than the opening extension period, the number of games in the opening extension period after the jackpot game is set to 20.

  On the other hand, when it is determined in the process of S800 that the present is the open extension period (S800: yes), “1” is added to the value of the extended-village counter. In other words, since the big hit lottery is won before the opening extension period ends, the big hit counter is counted up because the big hit is continuous (long range). Next, it is determined whether or not the advantageous big hit period flag is set to ON (S808). That is, when the big hit lottery is won, it is determined whether it was in an advantageous big hit period or an unfavorable big hit period. As a result, if the winning for the big hit lottery in the advantageous big hit period (S808: yes), the advantageous big hit period table described later is selected (S810), and the big hit lottery in the disadvantageous big hit period is selected. If so, a table for disadvantageous hit period, which will be described later, is selected (S812), and a value based on each table is set as the value of the fluctuation shortening counter (S814).

  FIG. 34 (a) is an advantageous jackpot period table used to determine the number of games during the extended extension period when the jackpot lottery is won in the advantageous jackpot period, and FIG. 34 (b) shows the disadvantageous jackpot period. This is a table for unfavorable big hit periods used to determine the number of games for the extended extension period when the big hit lottery is won. In both FIG. 34 (a) and FIG. 34 (b), the number of games in the open extension period is set corresponding to the number of consecutive big hit games (the value of the extended game counter).

  In the process of S814, referring to the advantageous jackpot period table or the disadvantageous jackpot period table, the number of games in the open extension period corresponding to the value of the extended game counter is set in the fluctuation shortening counter. Therefore, if the winning of the big hit lottery occurs during the advantageous big hit period, if the number of consecutive big hits is “2”, the number of games in the extended extension period is set to “30”, and “3” “40” times are set for the first time, and “50” times are set for the “4” time. Further, when the number of consecutive big hits is “5” or more, the number of games in the open extension period is set to “100”. On the other hand, if the winning of the big hit lottery occurs in the disadvantageous big hit period, if the number of consecutive big hits is “2” to “4”, the number of games in the extended extension period is “0” times. (That is, the opening extension period is not started after the end of the big hit game). However, when the number of consecutive big hits is “5” or more, the number of games in the extended extended period is set to “100” as in the case of winning the big hit lottery during the advantageous big hit period. Thus, when the number of games is set to the value of the shortening counter, the extended extension period ends with the start of the big hit game. Therefore, the flag that is set to ON among the disadvantageous big hit period flag and the advantageous big hit period flag Is set to OFF (S3630), the extension extension number setting process of the second embodiment is terminated.

  As mentioned above, since the number of games that the number of consecutive big hits (continuous villas) is large, the number of games in the opening extension period is set, so the player will win the jackpot lottery by the end of the opening extension period To expect. In addition, since the number of games during the extended extension period is set more in the case of winning the big hit lottery during the advantageous big hit period than in the case of winning the big hit lottery during the disadvantageous big hit period, However, we expect to win a big hit lottery with a particularly favorable period.

B-4. Gameability obtained by the second embodiment:
FIG. 35 corresponds to the identification symbols “1” to “6” (corresponding to the special symbols stop symbols TZ001 to TZ006 described above) displayed together on the effect symbol display device 27 when winning the big hit lottery. , It shows the probability of stop display when winning the jackpot lottery (sorting probability), the number of rounds of jackpot game, the period before and after the fall during the extended extension period (favorable jackpot period, unfavorable jackpot period) and the fall probability . In the second embodiment, by performing the above-described series of processing, as shown in FIG. 35, a big hit game having a different property for each identification symbol to be stopped and displayed is performed.

  As shown in FIG. 35, when the jackpot game is started after the identification symbols “5” and “6” are stopped and displayed, the jackpot game is started after the identification symbols “1” to “4” are stopped and displayed. Rather than being displayed, the probability of being stopped and displayed (distribution probability) is low, and the number of rounds of jackpot games is high, so it feels like a jackpot game with a high rare value has been started, and it can boost the excitement of gaming it can.

  Further, when the big hit game is started after the identification symbols “2”, “4”, “6” are stopped and displayed, the advantageous big hit period is set after the falling lottery, so that it is the same as the first embodiment. In addition, it is possible to effectively excite the player's gaming interest by winning the falling lottery. On the other hand, when the big hit game is started after the identification symbols “1”, “3”, “5” are stopped and displayed, the advantageous big hit period is set before winning the falling lottery. For this reason, the player must win the jackpot lottery before winning the falling lottery unlike the case where the jackpot game is started after the identification symbols “2”, “4”, “6” are stopped and displayed. Expect. Therefore, the player will change the target to be expected according to the identification information that is stopped when the big hit game is started (the expectation to win the early fall lottery, or to the wrong lottery) As a result, it feels like there is a different opening extension period, which will excite the entertainment of the game.

  In addition, since the probability of winning the falling lottery varies depending on the identification symbol that is displayed when the big hit game is started (when the identification symbols “2”, “4”, and “6” are stopped and displayed) Is the transition probability from the disadvantageous jackpot period to the advantageous jackpot period, and when the identification symbols “1”, “3” and “5” are stopped, the probability of transition from the advantageous jackpot period to the disadvantageous jackpot period), Checking the identification symbols that are displayed in a stopped state to determine whether or not it is easy to shift to the advantageous jackpot period (whether or not to easily shift to the disadvantaged jackpot period) Increase In addition, since the game in the easy-to-enter state is recognized after recognizing the ease of transition, it is possible to guess with a certain degree of certainty the possibility that an advantageous period will start, It can be greatly excited. In particular, when the jackpot game is started after the identification symbol “5” is stopped and displayed, the probability of shifting to the disadvantageous jackpot period is extremely low, and when the jackpot game is started after the identification symbol “6” is stopped and displayed. Has a very high probability of shifting to an advantageous jackpot period. That is, in any case, since the probability that the game can be advanced in the advantageous jackpot period is high, the player can further increase the rarity of the already-displayed identification symbols “5” and “6” being stopped. It feels strong, and it becomes possible to excite the player's gaming interest.

C. Modified example:
While various embodiments of the present invention have been described above, the present invention is not limited thereto, and is not limited to the wording of each claim unless it departs from the scope described in each claim. Improvements based on the knowledge that a person skilled in the art normally has can also be added as appropriate to the extent that those skilled in the art can easily replace them.

  For example, in the first embodiment, the advantageous jackpot period is set after the falling lottery win in the opening extension period, and in the second embodiment, the opening extension period is set for each identification symbol that is stopped when the jackpot game is started. It is set either before the falling lottery winning or after the falling lottery winning. On the other hand, each time the jackpot game is started or the opening extension period is started, it is determined whether the advantageous jackpot period is set before the falling lottery winning of the opening extension period or after the falling lottery winning You may make it do. In this way, each time the big hit game is started or the opening extension period is started, the player will pay attention to whether the effective big hit period is set before or after the falling lottery win, It will be possible to excite the game entertainment. Also, if the player is not notified of the advantageous jackpot period set before or after the falling lottery, the player must be in the advantageous jackpot period even if the current is in the disadvantageous jackpot period. In anticipation of this, since the game is advanced without cooling the game entertainment, it is possible to excite the game entertainment.

  In the first embodiment and the second embodiment (when the identification symbols “2”, “4”, and “6” are stopped and displayed in the second embodiment), the falling lottery is not won (the disadvantageous hit period). When the extended extension period ends, it is more disadvantageous than the advantageous jackpot period and more advantageous than the disadvantageous jackpot period (when winning the jackpot lottery, it is less disadvantageous than when winning the jackpot lottery during the advantageous jackpot period ( The number of games in the extended extension period is small), and the advantage (period in which the number of games in the extended extension period is started) that is more advantageous than the case where the big hit lottery is won in the disadvantageous big hit period is started. On the other hand, if the opening extension period ends without winning the falling lottery (with a disadvantageous bonus period), until the winning lottery is won, it is more advantageous than after winning the falling lottery ( When the big hit lottery is won, a period in which the number of games in the extended extension period is large) may be started. In this way, even if the extension extension period is ended without shifting to the advantageous jackpot period without winning the falling lottery (with the unfavorable jackpot period), the player proceeds with the game in the hope that he will win before the falling lottery I will let you. Therefore, the player expects to win the falling lottery during the opening extension period and shifts to the advantageous jackpot period, and expects not to win the falling lottery after the opening extension period ends. Therefore, it is possible to make the target to be different between the end of the opening extension period and the player's gaming interest.

  In the first embodiment and the second embodiment, the falling lottery is performed before the big hit lottery. However, whether the falling lottery is performed before or after the big hit lottery may be appropriately determined. For example, it may be determined whether the falling lottery is performed before or after the big hit lottery depending on whether the advantageous big hit period is set before or after the falling lottery winning.

  In the first and second embodiments, at least when the opening extension period is started, it is determined whether the advantageous big hit period in the opening extension period is set before or after the falling lottery win. Yes. On the other hand, after the opening extension period is started (during the opening extension period), the advantageous big hit period may be switched between before and after the falling lottery win (the period when the player is happy to fall) You can mix periods that you do n’t like) In this way, during the opening extension period, it is possible for a player to mix a game that he / she wants to win the falling lottery and a game that he / she does not want to win the falling lottery, and the player changes his expectation target during the opening extension period. As a result, it becomes possible to excite the entertainment of the game during the extended extension period. For example, every time the game during the extended extension period has passed 10 times, if the winning lottery is won, the player can switch between the period in which the advantageous jackpot period is started and the period in which the disadvantageous jackpot period is started. Every time 10 passes, whether or not you want to win the falling lottery is changed, so it is possible to excite the game entertainment.

  In the first embodiment and the second embodiment, it is decided that the player falls from the high probability state to the low probability state after winning by the falling lottery. It is also possible to cause the game to fall from a high probability state to a low probability state by performing a game (so-called “probability change state count cut”). For example, if the number of times of opening extension is 100 times, the prescribed number of symbol variable games in the high probability state is “1”, “2”, “3”, “98”, “99” Or “100 times”. The prescribed number of times is determined in association with the type of winning symbol that triggered the winning game. Even with this configuration, during the opening extension period, "high probability state during opening extension period (state before falling)" and "low probability state during opening extension period (state after falling)" are realized. In addition, by setting one state as the “favorable jackpot period” and setting the other state as the “unfavorable jackpot period”, it is possible to achieve the same effects as those of the first and second embodiments.

  The present invention can be used for a ball game machine used in a game hall.
