Abstract

PROBLEM TO BE SOLVED: In a conventional gaming machine, when a specific symbol combination is stopped and displayed, the player's sense of expectation is once lost.
In the pachislot machine 1, the first BB gaming state is advantageous in that the expected value of the probability lottery table is higher than that in the general gaming state and the lottery probability of the first RB is high. The second BB gaming state has the same expected value of the probability lottery table as the general gaming state, but is advantageous because the lottery probability of the first RB advantageous to the player is high. However, the lottery probability of the first RB is low and disadvantageous compared to the first BB gaming state. The third BB gaming state has the same expected value of the probability lottery table as the general gaming state, but is disadvantageous because the first BB and the second BB are not drawn. The fourth BB gaming state has the same expected value as the general gaming state, but is disadvantageous because the first BB and second BB lottery advantageous to the player is not performed. Also, the first RB lottery probability is low and disadvantageous as compared to the third BB gaming state.

Description

  The present invention relates to a gaming machine that gives a player a gaming value when a predetermined combination of symbols is displayed.

Conventionally, as such a gaming machine, for example, there is a so-called pachislot machine such as a slot machine disclosed in the following Patent Document 1 in which the rotation of a reel is stopped according to a player's operation. . In this pachislot machine, when a medal that is a game value is bet on the game and the start lever is operated, the internal winning combination is determined from a plurality of combinations by lottery using a lottery probability table, and subsequently in multiple columns. The arranged reels start to rotate. When a stop button provided corresponding to each reel is operated, the rotation of the reel is stopped according to the operation timing and the internal winning combination. At this time, when the combination of symbols shown on the outer peripheral surface of each reel is a combination corresponding to the winning combination related to winning, a medal payout is performed. When a specific symbol combination related to a specific winning combination such as a bonus is stopped and displayed, a bonus gaming state that is relatively advantageous to the player as compared with the general gaming state is activated.
JP 2000-210413 A (see paragraphs [0041] to [0061])

  In a conventional pachislot machine, generally, in a bonus game state, an internal winning combination is determined using a lottery probability table in which the probability of determining an internal winning combination related to winning is higher than that in the general gaming state. For this reason, when a specific symbol combination is stopped and displayed, it is certain that many medals will be paid out in the bonus game state that is operated thereafter, and therefore the player's sense of expectation has once been lost.

  The present invention was made to solve such a problem, and a symbol display means for displaying a plurality of symbols, a start signal output means for outputting a signal for instructing the start of a unit game based on a start operation, The winning combination determining means for determining the winning combination based on the signal output by the start signal output means, and the symbol changing means for changing the symbol displayed by the symbol display means based on the signal output by the start signal output means And a stop signal output means for outputting a signal for commanding stoppage of the symbol variation performed by the symbol variation means based on the stop operation, the signal output by the stop signal output means and the winning combination determined by the winning combination determining means Based on the combination, a combination of the stop control means for controlling the stop of the symbol variation performed by the symbol variation means and the symbol combination predetermined by the symbol display means is displayed. In the gaming machine having the game value providing means for giving the game value to the player, when the first specific symbol combination is displayed by the symbol display means, the player is compared with a predetermined gaming state. Advantageous state operating means for operating the first advantageous gaming state or the second advantageous gaming state, which are relatively advantageous and differing in degree, and the second specific symbol combination by the symbol display means When displayed, it is a disadvantage for the player as compared with the predetermined gaming state, and the disadvantageous state for performing the operation of the first disadvantageous gaming state or the second disadvantageous gaming state with different degrees. And operating means.

  According to this configuration, when the first specific symbol combination is displayed by the symbol display means, the first advantageous gaming state or the second advantageous gaming state is activated, and the second specific symbol combination is displayed. If so, the first disadvantageous gaming state or the second disadvantageous gaming state is activated. For this reason, even if a specific symbol combination is displayed on the symbol display means, the first advantageous gaming state or the second advantageous gaming state advantageous for the player as compared with the predetermined gaming state is not necessarily activated. However, the first unfavorable gaming state or the second unfavorable gaming state, which is disadvantageous for the player as compared with the predetermined gaming state, may be activated. As a result, even if a specific symbol combination is stopped and displayed, it is not always possible to receive a lot of game value. The player's interest in the symbol combination displayed on the symbol display means is increased, and the unit game result is increased. The tension of the player can be increased. Also, even when a gaming state advantageous for the player is operating, depending on whether it is the first advantageous gaming state or the second advantageous gaming state, Since the degree of advantage is different, it is possible to provide undulations in the game value payout amount. Further, even when a gaming state that is disadvantageous for the player is operating, the advantage for the player depends on whether it is the first disadvantageous gaming state or the second disadvantageous gaming state. Therefore, it is possible to provide undulations in the game value payout amount.

  Further, according to the present invention, the symbol variation means configures the second specific symbol combination within a predetermined number of symbols after displaying at least one symbol constituting the first specific symbol combination on the symbol display means. The symbol display means displays a symbol to be displayed, and the stop control means has a winning combination determining means within a predetermined number of symbols after the symbol displayed on the symbol display means when the signal is output by the stop signal output means. When a symbol corresponding to the winning combination determined by the above is included, this symbol is displayed on the symbol display means.

  According to this configuration, when a winning combination corresponding to the second specific symbol combination is determined as the winning combination by the winning combination determining means, the symbols constituting the first specific symbol combination are displayed on the symbol display means. The second specific symbol within the predetermined number of symbols after the symbols constituting the first specific symbol combination is stopped even if a stop operation is performed in which the signal to be output is output from the stop signal output means Displayed on the symbol display means by the control means, the first or second disadvantageous gaming state is activated. For this reason, the stop operation performed by the player aiming at the operation of the first or second advantageous game state induces the operation of the first or second disadvantageous game state. As a result, the gaming value given to the player is small, and the profit of the gaming store where the gaming machine is installed is ensured.

  Further, according to the present invention, the numerical information updating means for updating the numerical information based on the game value given to the player by the game value giving means, and the numerical information is updated to a predetermined value by the numerical information updating means. And an operation ending means for ending the operation of the first or second advantageous gaming state or the first or second disadvantageous gaming state.

  According to this configuration, the operation of the first to second advantageous game states or the first or second disadvantageous game state is completed based on the added value given to the player by the game value giving means. By calculating the assigned gaming value, the player can be given pleasure to predict the end of the operation of the first or second advantageous gaming state or the first or second disadvantageous gaming state.

  Further, according to the present invention, when the numerical information is updated to the first or second value by the numerical information updating means, the operation ending means activates the first advantageous gaming state or the second advantageous gaming state. When the numerical information is updated to the third or fourth value by the numerical information updating means, the operation of the first disadvantageous gaming state or the second disadvantageous gaming state is terminated.

  According to this configuration, since the period until the first and second advantageous gaming states end and the period until the operation of the first and second disadvantageous gaming states end are different, It is possible to increase the difference between the gaming value that the player can be given in the second advantageous gaming state and the gaming value that the player can be given in the first or second disadvantageous gaming state. And if it is an expert, it can stop the 1st or 2nd disadvantageous game state earlier by performing stop operation aiming at a predetermined symbol combination, Since such a stop operation cannot be performed, the difference in the advantage between the players can be made larger. Thereby, a big undulation occurs in the progress of the game, and the interest of the game is enhanced.

  According to the present invention, as described above, even when a specific symbol combination is stopped and displayed, a gaming state advantageous to the player as compared with a predetermined gaming state does not necessarily operate. The player's interest in the symbol combination displayed on the symbol display means can be increased, and the player's sense of tension with respect to the result of the unit game can be increased.

The sub control board 62 shown in FIG. 7 is provided with a main control unit communication port 88 for receiving this signal. Communication between the sub control unit communication port 79 and the main control unit communication port 88 is performed only in one direction from the sub control unit communication port 79 to the main control unit communication port 88. In the present embodiment, the signal sent from the sub-control unit communication port 79 to the main control unit communication port 88 is a 7-bit command type indicating the control type and a maximum 24-bit length command content. It is composed of the parameters represented.

  The sub control board 62 performs a predetermined effect based on a control signal from the main control board 61. The control unit in the sub-control board 62 is configured with the microcomputer 81 as a main component. Similarly to the microcomputer 63 on the main control board 61, the microcomputer 81 includes a sub CPU 82 that performs a control operation according to a preset program, a program ROM 83 that is a program storage unit, and a control RAM 84 with a backup function.

Further, the sub CPU 82 further transmits / receives signals to / from the main control unit communication port 88 and an actuator described later. / O port 87 is connected.

  As actuators whose operation is controlled by a control signal from the microcomputer 81, there are reel back lamps 47a to 47c built in the reels 2 to 4, respectively. Lighting of these back lamps 47 a to 47 c is controlled by a drive signal from a lamp drive circuit 89 connected to the I / O port 87.

  Further, as the input signal generating means for generating an input signal necessary for the microcomputer 81 to generate a control signal, there are the above-described cross key 23, “◯” button 24 and “×” button 25.

  The I / O port 87 is connected to an image control work RAM 98, a VDP (video display processor) 90, and a sound source IC 91. The VDP 90 is connected to a character ROM 92 storing character data, a video RAM 93 which is a color display display buffer memory, and an image control work RAM 98 is also connected. The VDP 90 displays an image on the liquid crystal display device 22 under the control of the microcomputer 81. The microcomputer 81 fetches information such as the gaming state at that time and the type of winning flag from the main control board 61 via the main control unit communication port 88, and selects an effect image to be displayed based on the fetched gaming state and winning flag. Then, the effect image selected by controlling the VDP 90 is displayed on the liquid crystal display device 22.

  In addition, a sound ROM 94 storing sound data is connected to the sound source IC 91, and the sound source IC 91 emits sound from the speakers 96 and 96 through the power amplifier 95 under the control of the microcomputer 81.

  This probability lottery table is used when an internal winning combination is lottery in the probability lottery process (FIG. 12, S6) of the main flowchart described later. The probability lottery table stores data which is generated by the random number generator 69 and which divides the random numbers extracted by the random number sampling circuit 70 into the internal winning combinations. Each internal winning combination is assigned a random number range in a predetermined numerical range from 0 to 16383 numerical data, and the internal winning combination assigned to the random number range to which the extracted random number value belongs is selected. That is, the internal winning combination is determined by which random number range the sampled one random number value belongs to, and is represented by the hit request flag.

In addition, an expected value is set for each internal winning combination. The expected value is the number of medals that can be paid out per medal bet on the unit game when three medals are bet on the unit game and the probability lottery process using the probability lottery table is performed. Say. The definition of the expected value is based on the assumption that the so-called pull-in rate is not taken into consideration, and there is no occurrence of an oversight that prevents winning of the internal winning combination. For example, in the probability lottery table shown in FIG. 8A, the expected value K for the small part of “Cherry” is two winning medals for the small part of “Cherry” and the winning probability of the small part of “Cherry” Is represented by the following formula (1).
K = 2 × (150/16384) /3=0.0001 (1)

  Next, the control operation of the main CPU 64 of the main control board 61 will be described with reference to the main flowchart shown in FIG.

  First, the main CPU 64 performs initialization at the start of the game (see S1 in FIG. 12). Specifically, the contents stored in the control RAM 66 are initialized, the communication data is initialized, and the like. Subsequently, the predetermined stored contents of the control RAM 66 at the end of the game are erased (S2). Specifically, the data in the writable area of the control RAM 66 used in the previous game is erased, the parameters necessary for the next game are written in the write area of the control RAM 66, and the start address of the sequence program of the next game is set. Make designations.

  Next, the main CPU 64 performs medal insertion / start check processing (S3). In this process, when it is determined that the requested number of medals has been automatically inserted, or based on inputs from the inserted medal sensor 8S or the stored medal insertion switches 26 to 28, the main CPU 64 The input from the start switch 30S based on the operation of the start lever 30 is confirmed. When the input from the start switch 30S is confirmed, the main CPU 64 extracts the random number for lottery generated by the random number generator 69 by the sampling circuit 70 (S4). Subsequently, the main CPU 64 performs a gaming state monitoring process described later (S5) and then performs a probability lottery process described later (S6).

  Next, the main CPU 64 transmits a start command to the sub control board 62 side via the sub control unit communication port 79 (S7). The “start command” is a command including information such as the gaming state identified in S5, the winning combination selected in the probability lottery process in S6, and the like.

  Subsequently, the main CPU 64 determines whether 4.1 seconds have elapsed since the start of the previous reel rotation (S8). When this determination is “NO”, the wait process (S9) is performed until 4.1 seconds elapse. In the weight process, a process of invalidating an input based on an operation of starting the game of the player (here, a process of waiting for the start of rotation of the reels 2 to 4) is performed.

  When 4.1 seconds have elapsed since the start of the previous reel rotation, the main CPU 64 sets a game monitoring timer in a predetermined area of the control RAM 66 (S10). This timer for game monitoring is a timer for monitoring the time of each unit game, and is used for automatic stop for automatically stopping the reels 2 to 4 without depending on the stop operation of the stop buttons 31 to 33 of the player. It also includes a timer.

  When the process of S10 ends, the main CPU 64 requests the start of rotation of all the reels 2 to 4 (S11), starts the rotation of all the reels 2 to 4, and subsequently sends a “reel stop permission command” to the sub-control unit. It transmits to the sub-control board 62 side via the communication port 79 (S12). The “reel stop permission command” is a command that allows the operation of the stop buttons 31 to 33 to be accepted. Next, the main CPU 64 determines whether or not the stop buttons 31 to 33 are operated and the stop switch is turned on (S13). If this determination is “NO” without any of the stop buttons 31 to 33 being operated, it is determined whether or not the value of the automatic stop timer is “0” (S14). When this determination is “NO”, the process returns to S13 and the above-described process is repeated.

  When any one of the stop buttons 31 to 33 is operated and the determination in S13 becomes “YES”, or when the value of the automatic stop timer becomes “0” and the determination in S14 becomes “YES”, next, the main CPU 64 Performs a sliding frame number determination process (S15). Here, “the number of sliding frames” indicates the number of symbols to be moved after the stop buttons 31 to 33 are operated and before the reels 2 to 4 are stopped, and may be referred to as “the number of pull-in”. is there.

  FIG. 15 is a diagram showing an outline of the sliding frame number determination process.

  In the sliding frame number determination process, first, the main CPU 64 determines whether or not the gaming state is the SCT gaming state (see S71 in FIG. 15). If this determination is “YES”, the SCT display permission is determined. Referring to the table (FIG. 10), one of 0 to 1 is determined as the number of sliding frames based on the type of combination permitted to be displayed and the operation timing of stop buttons 31 to 33 (S73). On the other hand, when the determination in S71 is “NO”, one of 0 to 4 is determined as the number of sliding symbols based on the internal winning combination and carryover combination (S72), and the process is terminated.

  After the sliding frame number determination process, the main CPU 64 waits for the reels 2 to 4 corresponding to the stop buttons 31 to 33 that have been stopped to rotate by the number of sliding frames (see S16 in FIG. 12). 4 is requested to stop the rotation (S17). Next, the main CPU 64 transmits a “reel stop command” to the sub control board 62 side via the sub control unit communication port 79 (S18). The “reel stop command” is a command including information that can identify the stopped reels 2 to 4 and information that can identify the type of the symbol displayed by the stopped reel on a predetermined activated pay line. .

  Subsequently, the main CPU 64 determines whether or not all reels are stopped (S19). If this determination is "NO", the process returns to S13, and the above-described processes are repeated. On the other hand, when all the reels 2 to 4 are stopped and the determination in S19 is “YES”, the main CPU 64 next performs a display combination search process (S20). In this display combination search process, the type of combination of symbols actually displayed on the activated winning line is matched with the type of winning combination determined by the probability lottery process.

  Next, it is determined whether there is an error in the display combination and it corresponds to an illegal hit (S21). If the determination result is an illegal hit, an illegal error is displayed on the payout number display unit 20 and the liquid crystal display device 22 (S22). If the display combination is normal and not an illegal hit, a “display combination command” is transmitted to the sub-control board 62 side via the sub-control unit communication port 79 (S23). The “display combination command” is a command including the type of combination of symbols that are actually displayed on the activated pay line.

  Next, the main CPU 64 determines whether or not the number of medals paid out by winning is 0 (S24). When this determination is "NO", the number of payouts is added to the numerical information stored in the control RAM 66. At the same time, the game medal is stored or paid out (S25). That is, if the game is played with credits, the number of stored coins displayed on the stored coin number display unit 16 is increased by the number of medals acquired by winning, and the game is performed by inserting medals into the medal slot 8. If it is in a state in which medals are performed, the number of medals won by winning a prize is paid out to the medal tray 37.

  When the determination in S24 is “YES”, or after performing the processing in S25, the main CPU 64 performs sub-control via the sub-control unit communication port 79 via the sub-control unit communication port 79, including the information indicating that the pay-out processing has been completed. It transmits to the board | substrate 62 side (S26).

  Subsequently, the main CPU 64 determines whether or not the first BB operating flag to the fourth BB operating flag, the CT operating flag, the SCT operating flag, the first RB operating flag, or the second RB operating flag is “ON”. Is discriminated (S27). If none of the flags is “ON”, the main CPU 64 next performs an operation check process for an accessory, which will be described later (S28). On the other hand, if any of the flags is “ON”, the main CPU 64 then performs a completion check process for an accessory etc. described later (S29). After these processes, the game process returns to S2 and the next new game is started.

  Next, with reference to FIG. 13, the gaming state monitoring process performed in FIGS. 12 and S5 will be described.

  In this gaming state monitoring process, first, the main CPU 64 determines whether or not the SCT operating flag is “ON” (see S41 in FIG. 13). When this determination is “YES”, the gaming state is set to the SCT gaming state (S42). On the other hand, when the determination in S41 is “NO”, it is determined whether or not the first to fourth BB operating flag, the CT operating flag, the first RB operating flag, or the second RB operating flag is “on”. (S43). When this determination is “YES”, the gaming state is set from the first BB general gaming state to the fourth BB general gaming state, the CT gaming state, the first RB gaming state, or the second RB gaming state (S44). That is, the gaming state corresponding to the on flag among the first BB operating flag to the fourth BB operating flag, the CT operating flag, the first RB operating flag, or the second RB operating flag is set. On the other hand, when the determination in S43 is “NO”, it is determined whether or not a carryover combination is set (S45). When this determination is “YES”, the gaming state is set to the first BB internal winning state to the fourth BB internal winning state, the CT internal winning state, the first RB internal winning state, or the second RB internal winning state according to the carryover combination. (S46). On the other hand, when the determination in S45 is “NO”, the gaming state is set to the general gaming state (S47). When the process of S42, S44, S46, or S47 is performed, the gaming state monitoring process ends.

  Next, the probability lottery process performed in FIGS. 12 and S6 will be described with reference to FIG.

  In this probability lottery process, first, the main CPU 64 determines whether or not the gaming state is the first to fourth BB general gaming state (see FIG. 14, S51), and when this determination is “YES”. Determines the internal winning combination based on the probability lottery table for the first BB general gaming state shown in FIG. 8 (c) to the probability lottery table for the fourth BB general gaming state shown in FIG. 9 (f) (S52). On the other hand, if the determination in S51 is “NO”, the main CPU 64 determines whether the gaming state is the first RB internal winning state or the second RB gaming state (S53), and this determination is “YES”. If it is, the internal winning combination is determined based on the table corresponding to the gaming state in the first RB gaming state probability lottery table or the second RB gaming state probability lottery table shown in FIG. 9 (h) or (i). (S54).

  On the other hand, if the determination in S53 is “NO”, the main CPU 64 determines whether or not the gaming state is an internal winning state (S55). If this determination is “YES”, Based on the internal winning state probability lottery table shown in FIG. 8B, an internal winning combination is determined (S56). On the other hand, when the determination in S55 is “NO”, the main CPU 64 determines whether or not the gaming state is the CT gaming state (S57), and when this determination is “NO”, the CT operation is performed. It is determined whether or not the middle flag is on (S58). When the determination in S57 or S58 is “YES”, the main CPU 64 determines an internal winning combination based on the CT gaming state probability lottery table shown in FIG. 9G (S59). The probability lottery table referred to when the gaming state is the SCT gaming state differs depending on the gaming state when the SCT gaming state is activated. That is, in the SCT gaming state operated in the general gaming state, the internal winning combination is determined based on the general gaming state probability lottery table (FIG. 8A), and in the SCT gaming state operated in the CT gaming state, An internal winning combination is determined based on the state probability lottery table (FIG. 9G).

  If the determination in S58 is “NO”, the main CPU 64 determines an internal winning combination based on the general gaming state probability lottery table shown in FIG. 8A (S60). After performing the processing of S52, S54, S56, S59, or S60, the main CPU 64 determines whether the internal winning combination is any one of the first to fourth BB, CT, first RB, or second RB. (S61) If this determination is “YES”, the carryover combination is set based on the internal winning combination (S62), and the process is terminated. On the other hand, if the determination in S61 is “NO”, the probability lottery process is terminated.

  Next, with reference to FIG. 16, the accessory etc. operation check process performed in FIG. 12, S28 is demonstrated.

  In this combination operation check process, first, the main CPU 64 determines whether or not the display combination actually displayed on the reels 2 to 4 is the first to fourth BBs (see FIG. 16, S81). ) If this determination is “YES”, the BB operation process is performed based on the BB operation table (see FIG. 11A) (S82). In this process, any one of the first BB operating flag to the fourth BB operating flag corresponding to the display combination is turned “ON”, the carryover combination is cleared, and the payable number of BBs corresponding to the display combination is set. Done. On the other hand, if the determination in S81 is “NO”, the main CPU 64 determines whether or not the display combination is CT (S83). If this determination is “YES”, the main CPU 64 is in CT operation. Based on the table (see FIG. 11B), the CT operation processing is performed (S84). In this process, a process is performed in which the CT operating flag is set to “ON”, the carryover combination is cleared, and the number of payable sheets is set.

  When the determination in S83 is “NO”, it is determined whether or not the display combination is SCT (S85), and when the determination is “YES”, the SCT operation processing is performed (S86). In this process, a process of setting the SCT operating flag to “ON” and setting the possible number of games is performed. When the determination in S85 is “NO”, it is determined whether or not the display combination is the first RB or the second RB (S87). End the check process. On the other hand, if the determination is “YES”, RB operation processing is performed based on the RB operation table (see FIG. 11C) (S88). In this process, a process is performed in which the RB operating flag is turned “ON”, the carryover combination is cleared, and the number of possible games and the number of possible winnings are set. After the processes of S82, S84, S86, and S88 are performed, the accessory operation check process ends.

  Next, with reference to FIG. 17 and FIG. 18, the completion check process of the accessory etc. performed in FIG. 12, S29 is demonstrated.

  In the completion check process of the accessory etc., first, the main CPU 64 determines whether or not the SCT operating flag is “ON” (see S91 in FIG. 17), and if this determination is “YES”. Then, an SCT end process is performed to end the SCT in one game by clearing the SCT operating flag (S92). If the determination in S91 is “NO”, the main CPU 64 determines whether any of the first to second RB operating flags is “on” (S93), and this determination is “NO”. If it is, the main CPU 64 determines whether or not the CT operating flag is “ON” (S98). If this determination is “YES”, the display combination is the first RB or the second RB. Whether or not (S99). When this determination is “YES”, the main CPU 64 performs the same RB operation process as described above based on the RB operation table (S100). If the determination in S99 is “NO”, the main CPU 64 updates the payout number in the CT gaming state (S101), and then the updated medal payout number becomes the payable number stored in the CT operation table. Based on whether or not it has been reached, it is determined whether or not the gaming state is at the end of CT (S102). If this determination is “YES”, a CT end process such as clearing the CT in-operation flag is performed (S103), and the accessory end check process is terminated. If the determination in S102 is “NO”, the end check process for the accessory etc. is ended as it is.

  If the determination in S93 is “YES”, the main CPU 64 updates the number of RB games and the number of winnings (S94). Next, the main CPU 64 determines that the gaming state is at the end of the RB based on whether or not the updated number of RB games or the number of winnings has reached the number of possible games or the number of winnings stored in the RB operation time table. (S95). If the determination is “YES”, an RB end time process such as clearing the RB operating flag is performed (S96). If the determination in S95 is “NO”, or after performing the process in S96, the main CPU 64 determines whether any of the first to fourth BB operating flags is “on” (S97). ) If this determination is “NO”, the end check process for the accessory etc. is ended as it is.

  If the determination in S97 is “YES”, or if the determination in S98 is “NO”, the main CPU 64 updates the payout number in the first BB gaming state to the fourth BB gaming state (see FIG. 18, S104). Based on whether or not the updated medal payout number has reached the payout possible number stored in the BB operation time table, it is determined whether or not the gaming state is the end of the first BB gaming state to the fourth BB gaming state. A determination is made (S105). If this determination is “YES”, processing at the end of BB is performed such as clearing the first to fourth BB operating flags to the fourth BB operating flag (S106), and the accessory completion check processing is terminated. If the determination in S105 is “NO”, the main CPU 64 determines whether or not the display combination is the first RB or the second RB (S107), and if this determination is “NO”, it is used as it is. The object completion check process is terminated. On the other hand, when the determination is “YES”, the RB operation time process is performed based on the RB operation time table (S108), and the accessory completion check process ends.

  In the pachi-slot machine 1 according to the present embodiment described above, the first specific symbol combination of “red 7-red 7-red 7” or “red 7-blue 7-red 7” is arranged along the activated pay line, When the display combination is determined to be the first BB or the second BB in S81 of the action checking process of the accessory etc. in FIG. The first BB or the second BB gaming state which is relatively advantageous to the player as compared with the above is activated. Further, the second specific symbol combination of “red 7-blue 7-blue 7” or “red 7-red 7-blue 7” is arranged along the activated pay line, and the operation check process of the accessory etc. of FIG. When the display combination is determined to be the third BB or the fourth BB in S81, the third BB or fourth BB in-operation flag is turned “ON” in the BB operation process in S82, and the player is relatively less than the general gaming state. The disadvantageous 3BB or 4BB gaming state is activated.

  According to the pachislot machine 1 according to the present embodiment, a specific symbol combination of “red 7-red 7-red 7” or “red 7-blue 7-red 7” is displayed by the reels 2 to 4 as described above. The first BB gaming state or the second BB gaming state, which is relatively advantageous to the player compared with the general gaming state, is activated, and “red 7-blue 7-blue 7” or “red 7-red 7-blue 7” When the specific symbol combination is displayed, the third BB gaming state or the fourth BB gaming state, which is relatively disadvantageous for the player as compared with the general gaming state, is activated. For this reason, even if a specific symbol combination is displayed on the reels 2 to 4, a game state advantageous to the player as compared with the general game state is not necessarily activated, and the game is compared with the general game state. A gaming state that is disadvantageous to the user may be activated. As a result, even if a predetermined symbol combination is stopped and displayed, it is not always possible to receive many medals, and the player's interest in the symbol combinations displayed on the reels 2 to 4 is increased, and the unit game It can increase the player's sense of tension over the results. Also, even when the first BB gaming state or the second BB gaming state is operating, the advantage for the player differs depending on whether it is the first BB gaming state or the second BB gaming state. Therefore, undulations can be provided in the amount of medals paid out. In addition, even when the third BB gaming state or the fourth BB gaming state is operating, the advantage for the player differs depending on whether it is the third BB gaming state or the fourth BB gaming state, Unevenness can be provided in the medal payout amount.

  Further, as shown in FIG. 4, the symbol column for the right reel 4 includes a symbol “red 7” having a code number “0” and a symbol “20” having a code number “20” within the range of four frames as the number of sliding frames. Blue 7 "is arranged. Therefore, in the probability lottery process (FIG. 12, S6), the third to fourth BBs corresponding to the symbol combinations of “red 7-blue 7-blue 7” or “red 7-red 7-blue 7” are the internal winning combinations. When determined, the symbol “red 7” constituting the symbol combination corresponding to the first to second BBs of “red 7-red 7-red 7” or “red 7-blue 7-red 7” is displayed on the reel 4 Even if the stop operation of the stop button 33 is performed at the same timing, the symbol combination of “blue 7” within the range of four frames of the symbol “red 7” constituting the symbol combination corresponding to the first or second BB The 3rd to 4th BB gaming states are displayed on the reel 4. For this reason, the stop operation performed by the player aiming at the operation of the first to second BB gaming states advantageous to the player induces the operation of the third to fourth BB gaming states disadvantageous to the player. As a result, less medals are awarded to the player, and the profit of the game store (hall) where the pachislot machine 1 is installed is secured.

  In addition, as shown in the BB operation time table of FIG. 11A, the operation of the first to fourth BB gaming states is completed based on the number of medals given to the player, so that the given medals are calculated. Thus, it is possible to give the player the pleasure of predicting the end of the operation of the first to fourth BB gaming states. Moreover, in the BB operation time table of FIG. 11 (a), the number of medals that can be paid out for the first to second BB gaming states is set to 360, 300, whereas the third to fourth BB gaming states. The medal payout number is set to 200 and 360, and the medal payout number is set to a different value between the game states. For this reason, since the period until the operation of the first to second BB gaming state ends and the period until the operation of the third to fourth BB gaming state ends, the player in the first to second BB gaming state Can be increased, and the medal that the player can receive in the third to fourth BB gaming states. In addition, a skilled person can end the 3BB gaming state or the 4BB gaming state which is disadvantageous to the player earlier by operating the stop buttons 31 to 33 aiming at the symbol combination related to the medal payout. However, if it is an unskilled person, since the operation of such stop buttons 31-33 cannot be performed, the difference of the advantage between players can be made larger. Thereby, a big undulation occurs in the progress of the game, and the interest of the game is enhanced.

  Further, in the third BB general gaming state probability lottery table (see FIG. 9 (e)) and the fourth BB general gaming state probability lottery table (see FIG. 9 (f)), each winning combination including replay is displayed. The lottery probability is substantially the same. For this reason, it is difficult for the player to distinguish between the third BB gaming state and the fourth BB gaming state, and even if it is the most unfavorable fourth BB gaming state, the third BB gaming is more advantageous than the fourth BB gaming state. The player can be expected to be in a state.

  In the above embodiment, the symbol combination corresponding to the first BB corresponds to “red 7-red 7-red 7”, the symbol combination corresponding to the second BB corresponds to “red 7-blue 7-red 7”, and the third BB. The case has been described where the symbol combination to be performed is “red 7-blue 7-blue 7” and the symbol combination corresponding to the fourth BB is “red 7-red 7-blue 7”. However, the symbol combinations corresponding to the first to fourth BBs are arbitrary. For example, the symbol combinations corresponding to the first to second BBs and the third to fourth BBs may be the same. According to this configuration, in the state where the third to fourth BBs are determined as the internal winning combination in the probability lottery process (FIG. 12, S6), the stop operation of the stop buttons 31 to 33 aiming for the first to second BB winnings Is performed, the third to fourth BB winnings are established, and the third to fourth BB gaming states are activated. For this reason, the stop operation performed by the player aiming at the operation of the first to second BB gaming states induces the operation of the third to fourth BB gaming states. As a result, less medals are awarded to the player, and the profit of the hall in which the pachislot machine 1 is installed is secured.

  If the first to second BB gaming states are relatively advantageous for the player compared to the general gaming state, and the third to fourth BB gaming states are relatively disadvantageous to the player compared to the general gaming state. For example, the configuration of each probability lottery table is arbitrary. For example, in the description of the above embodiment, the case where the internal winning combination is determined using the probability lottery table in which replay is determined as the internal winning combination in the probability lottery process of FIG. However, in the third to fourth BB gaming states, even if the internal winning combination is determined using the probability lottery table that has a high probability that the replay is not determined as the internal winning combination and the loss is determined as the internal winning combination. Good. According to this configuration, in the third to fourth BB gaming states, the player consumes more medals, and the difference between the number of medals that can be paid out by the skilled and unskilled players is increased. Can do.

  Further, in the above embodiment, the third to fourth BB gaming states are generally changed by setting the internal winning probability of the first RB in the third to fourth BB gaming states to a low value and not performing the first to second BB lotteries. Although the gaming state is more disadvantageous for the player than the gaming state, for example, when the loss is an internal winning combination, the number of sliding symbols is determined so that the loss becomes a display role regardless of the operation timing of the stop buttons 31 to 33 The number of sliding symbols may be determined in the process (FIG. 15) to enter an unfavorable gaming state. Further, it is possible to determine the number of sliding symbols in the sliding frame number determination process (FIG. 15) so that a combination with a small number of paid-out medals becomes a display combination, and enter an unfavorable gaming state. Moreover, in the said embodiment, it is the same value between each table of the probability lottery table for 1st BB general game states (FIG.8 (c))-4BB general game state probability lottery table (FIG.9 (f)). The winning probability of the small role is the winning probability of the small role in the probability lottery table for the third to fourth BB general gaming state is the winning probability of the small role in the first to second BB general gaming state probability lottery table. The first to second BB gaming states may be advantageous gaming states, and the third to fourth BB gaming states may be disadvantageous gaming states. In the above embodiment, the winning probability of the small role in the first and second BB general gaming state probability lottery tables is the same as the winning combination probability of the small role in the first BB general gaming state probability lottery table. The first BB gaming state may be made more advantageous than the second BB gaming state by making it higher than the winning probability of the small role in the 2BB general gaming state probability lottery table. Also, in the above embodiment, the winning probability of the small role that was the same value in the third and fourth BB general gaming state probability lottery table is the same as the winning probability of the small role in the third BB general gaming state probability lottery table. The fourth BB gaming state may be made more disadvantageous than the third BB gaming state by making it higher than the winning combination probability of the small role in the fourth BB general gaming state probability lottery table.

  In the above embodiment, the 3BB general gaming state probability lottery table (see FIG. 9E) and the 4BB general gaming state probability lottery table (see FIG. 9F) include replays. The case where the lottery probabilities of each winning combination are substantially the same has been described. However, in the first BB general gaming state probability lottery table (see FIG. 9 (c)) and the second BB general gaming state probability lottery table (see FIG. 9 (d)), each winning combination including replays is displayed. The lottery probabilities may be substantially the same. According to this configuration, it is difficult for the player to distinguish between the first BB gaming state and the second BB gaming state, and even if the player is in the second BB gaming state, which is disadvantageous than the first BB gaming state, The player can be expected to be in a state.

  In the pachislot machine 1 that outputs a signal for instructing the start of a unit game on condition that medals are inserted as in the above embodiment, it is expected that more medals than the number of inserted medals will be awarded to the player. It is more preferable that the game state is a relatively advantageous game state, and a state in which the number of medals exceeding the number of inserted medals is not expected to be given to the player is a relatively disadvantageous game state. is there. Specifically, in a relatively advantageous gaming state, the payout expectation rate at which a player can expect to receive a payout per medal bet on a unit game is set to a state exceeding “1”. In a disadvantageous gaming state, it is preferable that the payout expectation rate at which the player can expect to receive payout per medal bet on the unit game is less than “1”. The configuration as described above includes a plurality of types of probability lottery tables as in each embodiment, and in a relatively advantageous gaming state, the winning combination determining means has a specific internal winning combination (for example, replay, small combination) RB) may be determined with a relatively high probability, and in a relatively unfavorable gaming state, the winning combination determining means may determine a specific internal winning combination with a relatively low probability. In addition, in a relatively advantageous gaming state, the winning combination determining means can determine a specific internal winning combination, and in a relatively unfavorable gaming state, the winning combination determining means cannot determine a specific internal winning combination May be realized. In a relatively advantageous gaming state, the stop control means determines the number of sliding symbols (for example, 0 to 4 frames) having a relatively wide range as compared with the general gaming state, so that the reels 2 to 4 determine the predetermined number. The symbol combination (for example, a chance symbol or a blank symbol without a symbol drawn) is controlled so that it is displayed with a relatively high probability compared to the general gaming state, and in a relatively unfavorable gaming state The stop control means determines the number of sliding symbols (for example, 0 to 3 frames) having a relatively narrow range compared with the general gaming state, and the predetermined symbol combination is compared with the general gaming state by the reels 2 to 4. The stop control may be performed so that the display is performed with a relatively low probability.

  Further, an advantageous effect state in which an effect advantageous to the player is made using the liquid crystal display device 22 and the speakers 96, 96, etc., an unfavorable effect state in which an effect is disadvantageous to the player, and depending on the situation, An advantageous gaming state and an unfavorable gaming state may be realized as a configuration including the effect actuating means for actuating either one. In addition, as the advantageous performance state, for example, the winning combination determined by the winning combination determining means is notified with a relatively high probability compared to the general gaming state (corresponding to the above-mentioned ST), or general assistance is provided. The gaming state can be performed with a relatively high probability compared to the gaming state. Further, as the disadvantageous effect state, for example, the winning combination determined by the winning combination determining means is notified with a relatively low probability compared to the general gaming state, or the assistance for pushing is relatively compared to the general gaming state. The gaming state can be performed with a low probability. In the case of such a configuration, for example, the present invention can be realized and the program capacity can be reduced without storing a plurality of types of probability lottery tables for determining an internal winning combination.

  Moreover, it is good also as a structure further provided with the state production | presentation means which performs the production which makes the game state at that time clear. The effect by the state effect means can be realized by performing an effect synchronized with the gaming state at that time and the operating flag. In the case of such a configuration, for example, it can be expected that the player can avoid starting the unit game without knowing that the second specific symbol combination is displayed and the disadvantageous gaming state is activated.

  Moreover, it is good also as a structure further equipped with the state suggestion means which performs the production | generation which suggests the game state at that time implicitly. The effect by the state suggestion means can be realized by determining the effect content based on a predetermined lottery as well as the game state and operating flag at that time, and performing the effect according to the determination result. In the case of such a configuration, for example, it is possible to give the player a sense of expectation that the player may be in an advantageous game state while being in a disadvantageous game state for the player, and maintain the player's interest. The effect of raising the operation can be expected.

  In the above embodiment, the case where the gaming machine according to the present invention is applied to the slot machine has been described. However, when the first specific symbol combination is displayed, a gaming state advantageous to the player is activated, It is also possible to apply the present invention to other gaming machines in which a gaming state that is disadvantageous to the player is activated when a specific symbol combination is displayed. Even when the present invention is applied to such a gaming machine, the same effects as the above-described embodiment can be obtained.
