Description

  The present invention relates to a pachislot machine, a pachinko machine, and other gaming machines that can stop the display of symbol variation by a player's operation so that a specific winning mode is established.

  Conventionally, a slot machine equipped with a stop button, a so-called pachislot machine, is a mechanical symbol display device configured by arranging a plurality of reels in which a plurality of symbols are arranged on the peripheral surface in the front window, or an alternative to this. Thus, an electrical symbol display device that displays the symbols on the reel in a pseudo manner is provided.

  In such a gaming machine, the reel rotates in accordance with the player's game start operation, and the displayed symbol varies depending on the rotation operation of the reel. This variation in symbols is controlled to be stopped for each reel based on the player's reel stop operation or the passage of a fixed time. When all the reels are stopped, if the combination of symbols of each reel that is stopped and displayed in the display window (hereinafter referred to as “stop symbol”) is in a predetermined stop mode, medals, coins, and other game media are paid out, It is a prize that gives a player a game value. The amount of game media to be given varies depending on the combination of stop symbols.

  In many current pachislot machines, the reel stop mode is not determined only by the player's stop operation timing but depends on the internal lottery result of the game machine. This is because if the symbol stop mode is determined only by the player's stop operation timing, the game result (win / loss) is determined by the player's skill level, and the game's soundness cannot be maintained. In addition, it is a high threshold for those who try to play a new game, and an increase in the number of players cannot be expected. Furthermore, it is difficult for the game hall (hall) to manage the payout rate of game media.

  Here, the internal lottery is generally performed by the following process. First, one or a plurality of random numbers are sampled from a random number generator provided in the gaming machine in response to a start signal output by the game start operation of the player. Next, in the microcomputer inside the gaming machine, the winning combination determination table stored in advance in the storage means in the gaming machine is compared with the sampled random number. As a result of the collation, winning winning combination information is transmitted from the microcomputer inside the gaming machine to the reel control means, and the combination of stop symbols is determined together with the stop operation timing of the player.

  Therefore, when the game is played continuously, the winning or losing of the game greatly depends on the result of the internal lottery. Here, a general pachislot machine is provided with setting means for setting a setting value that determines the degree of advantage of the player. A plurality of winning combination determination tables are stored corresponding to the set values, and the table is set such that the higher the set value, the higher the expected number of game media payouts.

  Therefore, it is important for a player to identify a gaming machine with a high setting value and select and play a game, and at the same time to guess the setting of the gaming machine that is playing itself. However, there is a current situation that this has contributed to improving the fun of games for players. Thus, as a prior art document disclosing a gaming machine characterized by presenting a setting estimation element of a gaming machine, for example, the following can be cited.

JP-A-2005-708 JP 2004-275705 A JP 2003-245403 A JP 2004-350991 A

  Patent Document 1 discloses a gaming machine in which a standby image on an effect screen in a non-game state changes according to a setting value, the number of games, a payout rate, and the like. Patent Document 2 discloses a gaming machine that can enhance the expectation without excessive gambling and sustain the interest of the player. Patent Document 3 discloses a gaming machine in which a player is notified of the stage of setting a payout rate, and the player can recognize the stage of setting a payout rate set in the gaming machine. Patent Document 4 discloses a gaming machine having different selection ratios of effective lines in which predetermined symbols are arranged according to settings.

  However, in any of the disclosed gaming machines, it is assumed that the setting and the game play rate are directly correlated, and all the players are searching for a game machine with a high game play rate. On the other hand, since there is an upper limit in the adjustment of the payout rate in the hall, the number of game machines with a high payout rate is also limited accordingly. For this reason, the table where the player is separated as a result of the setting determination can be easily estimated from the player that the setting of the payout rate is low, so operation can hardly be expected during that business day, This leads to a decrease in the overall occupancy rate. In this way, only the entertainment of the game that provides an element that can discriminate the setting that directly correlates with the appearance rate will result in the stagnation of the sales of the hall, and the adjustment of the appearance rate will be severe. As a result, the attractiveness for the player is also reduced.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a gaming machine that can provide a new selection determination element that is not only the magnitude of the payout rate when a player selects a game machine.

The image ROM 86 stores dot data for forming an image. The video RAM 87 is configured as a temporary storage unit when the image control IC 82 forms an image.

(Game state)
The gaming machine 1 configured as described above causes three types of game states to appear: “general game state”, “BB general game state”, and “RB game state”. Each of these “three types” of game states basically includes the types of roles that may be won internally, the probability of winning internally for replays, the types of bonuses that can achieve winnings, and internal winnings. It is distinguished by the relationship with winning a prize.

  The characteristics of each gaming state, that is, the type of the winning combination in each gaming state, the probability thereof, and the stop control of the reels 3L, 3C, 3R in each gaming state (the types of winning combinations that may be won) will be described later. To do. Further, the transition between the game states is performed when a combination of bonus symbols is displayed on the winning line.

  Here, the BB game state, which is triggered by the establishment of a BB prize and is constituted by the “BB general game state” and the “RB game state”, is hereinafter collectively referred to as “BB game state”. The BB winning is established by arranging “blue 7-blue 7-blue 7” or “red 7-red 7-red 7” along the active line in the general gaming state. After the BB winning is established, the gaming state becomes the BB general gaming state. The RB winning is established by arranging “red 7-red 7-blue 7” along the active line in the general gaming state or the BB general gaming state. The establishment of RB winning in the BB general gaming state is generally referred to as “JACIN”. After the RB winning is established, the gaming state becomes the RB gaming state.

  The winning of the replay role (replay) is established by arranging “Replay-Replay-Replay” in the general gaming state. When the replay winning combination is established, the same number of medals as the number of inserted medals are automatically inserted, so that the player can play the next game without consuming the medals.

  In addition, in the general game state and the BB general game state, winning of “upper chile small role”, “lower chile small role”, “watermelon small role” and “bell small role” may be realized. Is possible. The winning combination of winnings is established by arranging “Replay-Replay-Replay”, “Red 7-Replay-Replay” or “Blue 7-Replay-Replay” in the RB gaming state. When the number of winning winnings of the bonus becomes “8”, or when 12 games are completed, the gaming state shifts. Here, a game in an RB gaming state in which a winning combination of winnings may be established is generally referred to as a “JAC game”.

  Next, a description will be given of the relationship between the symbol combination indicating the winning and the number of medals to be paid out. In the general gaming state, there is a possibility of winning a prize for BB, RB, replay, bell small part, watermelon small part, upper chile small part and lower chile small part. Then, if the winning is BB or RB, 15 medals are paid out, and in the case of replay, no medals are paid out. Also, in the case of a small role of bell, watermelon, upper dust, and lower dust, ten, three, one, and seven medals are paid out, respectively.

  Also, in the BB general gaming state, there is a possibility of winning the RB and bell small part, the watermelon small part, the upper chile small part and the lower chile small part. If the winning combination is RB, 15 medals are paid out. Also, in the case of a small role of bell, watermelon, upper dust, and lower dust, ten, three, one, and seven medals are paid out, respectively. In addition, in the RB gaming state, when a winning combination of an accessory is established, 15 medals are paid out.

(Data table of main control circuit 71: probability lottery table)
Next, a probability lottery table used when determining the winning combination in each gaming state will be described with reference to FIGS.

  The probability lottery table is provided for each setting and for each gaming state. In this probability lottery table, an internal winning combination is associated with a winning probability at which each internal winning combination is determined. Note that the random number ranges used in the probability lottery tables of setting 1 and setting 2 are both “0 to 16363”.

  In the general game state probability lottery table shown in FIGS. 5A and 5B, “upper chilli”, “lower chilli”, “watermelon”, “bell”, “replay (replay)”, and “BB” “RB” and “losing” exist as internal winning combinations, and the winning probabilities are as shown.

  Specifically, for example, if the BET number is “3”, the small part of “Upper Chile”, when a random number range of “0” to “19” is extracted, is an internal winning with a probability of 20/16384 To do. Similarly, if the number of BETs is “1”, a small part of “Upper Chile” is won internally with a probability of 10/16384, and if the number of BETs is “2”, “Upper Chile” with a probability of 14/16384. 』Won the internal winning role. For example, if “BB” has a BET number of “3”, a random number range of “2646” to “2713” is extracted in setting 1 and “2741” to “2808” in setting 2 When the random number range is extracted, an internal winning is made with a probability of 68/16384.

  Note that the winning probability of “replay (replay)” is different between setting 1 and setting 2, and setting 2 has a higher probability of internal winning in “replay (replay)” than setting 1.

  Specifically, in the setting 1 (see FIG. 5A), if the BET number is “3”, a random number range of “401” to “2645” is extracted with a probability of 2245/16384. Internal winning for replay role. On the other hand, in the setting 2 (see FIG. 5B), if the BET number is “3”, when the random number range of “401” to “2740” is extracted, it becomes a replay combination with a probability of 2340/16384. Win internally. Therefore, although the probability of winning the replay combination is different, it is a very small difference, and it is a gaming machine that is difficult for a player to judge. This makes it possible to provide a gaming machine whose setting is not easily determined by the player, and to prevent the player from losing interest in the game.

  In the probability lottery table for the BB general gaming state shown in FIG. 6, “upper chile”, “lower chile”, “watermelon”, “bell”, “RB”, and “losing” exist as internal winning combinations, The winning probability is as shown in the figure.

  Specifically, for example, if the BET number is “3”, the small part of “Upper Chile”, when a random number range of “0” to “20” is extracted, the internal winning with the probability of 21/16384 To do. Similarly, if the number of BETs is “1”, the winning combination of “Upper Chile” will be won internally with a probability of 11/16384, and if the number of BETs is “2”, the probability of “Upper Chile” will be 15/16384. 』Won the internal winning role. Also, for example, if “RB” has a BET number of “3”, when a random number range of “10001” to “14097” is extracted for both setting 1 and setting 2, internal winning is performed with a probability of 4097/16384 .

  In the RB gaming state probability lottery table shown in FIG. 7, “losing” and “combination” exist as internal winning combinations, and the winning probabilities are as shown.

  Specifically, if the number of BETs is “3”, “losing” is won internally with a probability of 3/16384 when a random number range of “0” to “2” is extracted. Similarly, if the BET number is “1”, the “losing” small role is won internally with a probability of 1/16384, and if the BET number is “2”, the probability of “losing” is 2/16384. Wins a small role internally. In addition, if the BET number is “3”, the “combination” is won internally with a probability of 16381/16384 when the random number range of “3” to “16383” is extracted. Similarly, if the number of BETs is “1”, it will be internally elected to “Combines” with a probability of 8027/16384, and if the number of BETs is “2”, it will be internally placed in “Combined Items” with a probability of 11467/16384. Win. Note that the RB gaming state is a state in which the RB has already been established internally, so there is no possibility that the RB will be determined again.

  Each table as shown in FIGS. 5 to 7 is stored in the ROM 32 in the main control circuit 71 of FIG.

(Relationship between gaming state, internal winning combination, and selected stop table group)
Next, with reference to FIG. 8, FIG. 9, the relationship between the gaming state, the internal winning combination, and the stop table group to be selected will be described. The stop table group is selected at the time of stop control of the reels 3L, 3C, and 3R.

  Here, the contents of the selected stop table group can basically change according to the gaming state, the internal winning combination, etc., but in the present embodiment, the table group shown in the stop table group column. Is basically determined based on whether or not there is a possibility of winning a prize and the types of roles that have the possibility of winning. For this reason, in the present embodiment, even when stop table groups having the same name are selected, the stop mode of the reels 3L, 3C, and 3R does not always match.

  When a winning / non-winning stop table group is selected, no winning of any combination will be established regardless of the internal winning combination or gaming state. When the winning table for which winning can be established is selected, the winning combination of the corresponding combination is possible, but it is basically impossible to realize the winning combination of other combinations. For example, when the “watermelon winning establishment possible stop table group” is selected, winning establishment of “watermelon small role” can be realized, but winning establishment of other combinations such as BB cannot be realized. Further, when the “re-game winning establishment possible stop table group” is selected, winning establishment of “re-game” can be realized, but winning establishment of other roles cannot be realized.

  As shown in FIG. 8, when a bonus (RB, BB) is won internally in the general gaming state, a stop table group that can be awarded is selected. For this reason, it is possible to realize a bonus winning.

  As shown in FIG. 9, in the BB general gaming state and the RB gaming state, the illustrated stop table group is selected, and the stop control of the reels 3L, 3C, and 3R is performed. Specifically, if an RB or a winning combination is won internally (in the case of RB, JACIN), a winning establishment possible stop table group corresponding to each is selected.

(Operation of main control circuit 71: main routine)
In the above configuration, the control operation of the CPU 31 of the main control circuit 71 will be described with reference to the main flowchart shown in FIG.

  First, when the power is turned on, the gaming machine 1 is ready to play a game by executing the main routine of FIG. 10 in the main control circuit 71, and executes a reset routine (not shown) in the sub control circuit 72. By doing so, the display of the effect image of the liquid crystal display device 5 or the like becomes possible.

  Specifically, when a main routine or the like is executed by the main control circuit 71, as shown in FIG. 10, after the game is initialized (S1), a predetermined storage in the RAM 33 at the end of the game is performed. The contents are erased (S2). Next, a medal insertion process is executed, and a standby state is entered until there is an input from the BET switches 11S, 12S, 13S, etc. (S3). When there is an input from the BET switches 11S, 12S, 13S, etc., a medal insertion signal is transmitted to the sub control circuit 72 as a unit game start signal. Subsequently, it is determined whether or not the start switch 6S is turned on by operating the start lever 6 (S4). If the start switch 6S is not turned on (S4, NO), S4 is re-executed and the standby state is kept until the start lever 6 is operated. When the start switch 6S is turned on (S4, YES), execution is shifted to reel rotation processing (S5). Then, random numbers for lottery are extracted (S6), and the gaming state in the current game is confirmed by executing the gaming state monitoring process (S7).

  If the game state of the current game is confirmed, then a probability lottery process is performed (S8). In this probability lottery process, the CPU 31 performs a process of determining an internal winning combination based on the probability lottery table corresponding to the set value and the gaming state. Then, the information of the selected internal winning combination is output to the sub control circuit 72.

  When the internal winning combination is determined, stop table group selection processing is executed (S9). Then, after the reel rotation stop process is executed and the number of sliding frames is determined at the timing when any one of the stop buttons 7L, 7C, 7R is operated or when the value of the automatic stop timer becomes “0”, The reels are rotated by the number of frames and then stopped (S10). After this, the winning combination (winning combination) is identified based on the stop state of the symbols of the display windows 4L, 4C, 4R by winning determination (winning search) (S11), and the winning signal is used as the end signal of the unit game. It is output to the sub control circuit 72. Then, a medal credit or payout is performed according to the gaming state (S12). When it is determined that the winning combination is BB or RB, the BB general gaming state or the RB gaming state is generated.

  Next, it is determined whether or not the current gaming state is the BB general gaming state or the RB gaming state (S13). When the gaming state is not the BB general gaming state or the RB gaming state (S13, NO), S2 is re-executed. On the other hand, when the game state is the BB general game state or the RB game state in S13 (S13, YES), a bonus “game number check process” is performed (S14). Thereafter, it is determined whether or not the bonus is over (S15). If it is determined that the bonus is not over (S15, NO), S2 is re-executed. On the other hand, if it is determined that the bonus is over (S15, YES), a bonus end signal is output to the sub-control circuit 72 (S16), and S2 is re-executed.

(Operation of main control circuit 71: initialization routine)
Next, an initialization routine in the initialization process (S1) at the start of the game shown in FIG. 10 will be described with reference to FIG.

  First, power is turned on (A1). Subsequently, all output ports of the CPU 31 are initialized (A2). Subsequently, it is determined whether or not there is a power-down error of the gaming machine 1 (A3). If it is determined that there is a power-down error (A3: YES), A2 is re-executed and all output ports are initialized again.

  On the other hand, if it is determined that there is no power-down error (A3: NO), the CPU 31 is initialized (A4). Next, it is determined whether or not the RAM 33 has an error (A5). When it is determined that the RAM 33 is in error (A5: YES), the CPU 31 issues a signal for displaying a RAM error, and displays that fact by, for example, the 7-segment LED of the bonus game information display unit 20. Here, the RAM error means a state in which the RAM 33 cannot normally perform writing / reading processing.

  On the other hand, when it is determined that the RAM 33 is not in error (A5: NO), it is determined whether or not the setting key switch (key switch) 53S is on (A6). Specifically, this processing is as follows. In the process of A1, for example, the employee turns on the power switch while the setting key switch 53S is turned on. Then, a signal indicating that the setting key type switch 53S is ON is transmitted to the CPU 31. The CPU 31 determines whether or not the setting key type switch 53S is on based on whether or not a signal indicating that the setting key type switch 53S is on is acquired.

  When it is determined that the setting key switch 53S is on (A6: YES), a signal indicating the set value is acquired by the CPU 31 (A7). Specifically, when the power switch is turned on while the setting key type switch 53S is turned on, the setting button 52 can be operated. For example, the employee operates the setting button 52 to set the above two setting values. One of the setting values (setting 1, setting 2) is set. This set value is stored in the RAM 33, and a random number range extracted by the sampling device 37 and a probability lottery table stored in a predetermined area of the RAM 33 are determined based on this set value.

  On the other hand, when it is determined that the setting key switch 53S is OFF (A6: NO), it is determined whether or not the battery backup is normal (A8). When it is determined that the battery backup is normal (A8: YES), after the information written in the unused area of the RAM 33 is erased, all the registers of the CPU 31 are restored to the output state when the power is shut off (A9). ), The process returns to the main routine.

  On the other hand, when it is determined that the battery backup is not normal (A8: NO), various initial values are set in the CPU 31 (A10). Subsequently, the information written in the entire area of the RAM 33 is erased (A11). Here, the processing after A11 is also performed when it is determined in A6 that the setting key type switch 53S is ON and a signal indicating the setting value is acquired.

  Subsequently, various values including the set value are stored in the CPU 31 (A12). At that time, the set value information may be transmitted to the sub-control circuit 72. Thereafter, the communication data is initialized (A13), and the process returns to the main routine.

(Operation of sub-control circuit 72)
When various processes are executed by the routines in the main control circuit 71, results and contents corresponding to the processes are input to the sub-control circuit 72 as commands and data. In the sub control circuit 72, a reset routine (not shown) and the like are independently executed. Then, an effect image based on the command is displayed on the liquid crystal display device 5 by executing the reset routine. For example, when a command indicating the insertion of a medal is input, an effect image or the like that prompts an operation of the start lever 6 is displayed on the liquid crystal display device 5. Further, by random number sampling executed on the operation program of the sub CPU 74, the lottery probability of the replay role in the main control circuit 71 is set to any one of the liquid crystal display device 5, the speakers 21L and 21R, and the LED lamp 29 with a predetermined probability. Announces through a combination of

(Outline of this embodiment)
As described above, the gaming machine of the present embodiment includes a game start command means (start lever 6, start switch 6S, etc.) for instructing the start of a game, and a symbol display means (stepping motor) capable of variably displaying a plurality of symbols. 49L / 49C / 49R, reel position detection circuit 50, reels 3L / 3C / 3R, etc., and internal winning combination determining means (main control circuit 71) for determining the internal winning combination by lottery based on the start of the game and the game state. , The main routine of FIG. 10, etc.), setting means (setting key type switch 53S for setting, setting button 52, etc.) for changing the lottery probability of the replay combination in the internal winning combination determining means, and the variation of the symbols based on the internal winning combination Game value giving means (main control circuit 71, main routine in FIG. 10, hopper 4) that gives a game value when the result of the display being stopped is a predetermined stop mode. , A hopper drive circuit 41, there is a medal detection unit 40s, etc.), the structure having.

  According to the above configuration, by changing the lottery probability of the replay role by the setting means, it is possible to obtain gaming machines having different degrees of advantage to which the gaming value is given, so that a large number of gaming machines having the same content are arranged. Even in such a case, it may be possible to provide the player with a new determination element of selecting an advantageous one from these gaming machines.

  In the gaming machine of the present embodiment, the internal winning combination determining means includes random number generating means (random number generator 36, sampling circuit 37, etc.) for generating random numbers based on a predetermined input signal, and internal winning combination. A storage means (RAM 33, etc.) for storing a probability lottery table for setting a lottery probability of an internal winning combination by associating with a random value that can be generated by a random number generating means in accordance with a change in the lottery probability of the game state and the replay role; The setting means is configured to change the lottery probability of the replay combination by selecting the probability lottery table at the time of the lottery in the internal winning combination determination means.

  According to said structure, a lottery probability may be able to be changed by simple operation of selecting a probability lottery table with a setting means.

  Further, in the gaming machine of the present embodiment, the setting means is configured to be able to change the lottery probability of the replay combination in two stages. According to the above configuration, the game value grant rate may be converged to a certain range between different lottery probabilities, which may make it easier to manage the game value grant rate of the game hall. .

  In detail, when selling the gaming machine 1, it is necessary to pass a predetermined test in advance, and as one of the requirements, the payout rate of the medal 115 (the payout rate) converges within a predetermined range. Need to be. That is, in the case of 17,500 trials, the relationship between the total number of acquired medals 115 and 115 N inserted medals converges within the range of “0.55N ≦ M ≦ 1.2N”. (Rules regarding the recognition of the gaming machine 1 and the type certification, etc.). Here, in the gaming machines 1 that are currently distributed, it is common that there are six stages of setting values. In addition, the difference in the payout rate (race rate) between the set values can be attributed to the advantage of the player by adjusting the lottery probability and loss probability of bonuses (big bonus (BB) and regular bonus (RB)). The degree is adjusted, and for a winning combination other than a bonus (a winning combination that is generally referred to as a small role), there is a slight difference for a specific single small role even if there is a difference or difference between the set values. Most of them made a difference. This means that if there is a difference in the lottery probability between the set values for the winning combination including the small part, the payout rate (outtake rate) is difficult to converge as a result, and there is a possibility that the above test criteria will not be satisfied in the test This is because of the increase. As a result, it is designed with the aim of converging to a predetermined range. However, if the number of settings is as large as six stages in order to design for the limit of the predetermined range, it will be difficult to design. Become.

  For this reason, as a method for providing a difference in the lottery probability of the small role among the set values, the payout rate (the payout rate in the trial) is set by changing the number of set value stages from two to two. ) Can be reduced, and even if there is a difference in the small lottery probability between the individual set values, it is possible to converge to the range of the payout rate (delay rate) that passes the test There is. As a result, it may be easier to manage the game value grant rate of the game hall.

  Furthermore, if two or more levels of settings are possible and the number of setting options increases, it becomes difficult for the player to apply the settings, and the game is interesting because the settings are easily guessed by the player. Although the possibility of occurrence of the problem of lowering of the height is reduced, according to the configuration of the present embodiment, even when the number of settings is reduced to two stages, it is possible to suppress the reduction of the fun. There is.

  In addition, there is a slight difference in the lottery probabilities between the settings, except for the bonus roles such as the small role or replay role, or the special lottery probability of bonus winning is changed slightly between the settings. The new fun of inferring the setting by the player (it is difficult to guess at the 6th level, the setting is inferred by the hall side by making it clear, or the 6th level is a good setting) Can only provide vague inferences). In some cases, a setting with a high expected value may have a slightly lower lottery probability for a small role.

  In addition, the gaming machine of the present embodiment further includes notifying means (sub-control circuit 72, liquid crystal display device 5, speakers 21L / 21R, LED lamp 29, etc.) for notifying the lottery probability of the replay role at a predetermined probability. It is configured. According to the above configuration, since the player may be able to know the lottery probability of the replay role during the game, the game is repeatedly performed in order to know the information of the lottery probability. May be improved.

  In the above-described embodiment, the change between the setting of the winning probability of the replay combination is set only in the general gaming state, but is not limited thereto, and may be set in the BB general gaming state. In this way, the number of determination factors for the player to determine the setting increases, and the player concentrates on the game, thereby preventing the interest in the game from being impaired.

  In the above-described embodiment, the example in which the sampling circuit in the sub-control circuit 72 is used as the notification means for reporting the random number range that can be generated with a predetermined probability has been described. However, the present invention is not limited to this. The sampling circuit 37 may be used.
