Description

  The present invention relates to a gaming machine.

  For example, a slot machine equipped with a stop button, a so-called pachislot machine, has a variable display device configured by arranging a plurality of mechanical rotating reels that display a plurality of symbols in the front display window, or a symbol on the reel on the screen. It has an electrical fluctuation display device for displaying. In response to the player's start operation, the control means drives the variable display device to rotate each reel so that the symbols are displayed in a variable manner. After a certain time, automatically or by the player's stop operation, Stop rotation sequentially. At this time, when the symbols of the reels appearing in the display window become a specific combination (winning symbol), a profit is given to the player by paying out game media such as coins and medals.

  Currently, the mainstream model has a plurality of types of winning modes. In particular, when a predetermined winning combination is established, a single coin is not paid out, and the gaming state is better in condition than the normal state for a predetermined period. As such a combination, a combination that can play a game that gives a relatively large profit to the player a predetermined number of times (referred to as “Big Bonus”, hereinafter abbreviated as “BB”) and a relatively small profit to the player There is a role that can play a predetermined number of games (referred to as “regular bonus”, hereinafter abbreviated as “RB”).

  In addition, in current mainstream models, a predetermined combination of symbols is arranged along an activated formation line (hereinafter referred to as an “effective line”), and in order to establish a winning in which coins, medals, etc. are paid out, A combination of symbols indicating that the winning combination of the winning combination (hereinafter referred to as “internal winning combination”) and winning the winning combination (hereinafter referred to as “internal winning combination”) is effective The player is required to perform a stop operation at an appropriate timing at which the player can stop at the line. In other words, no matter how much internal winning is made, if the timing of the stop operation of the player is bad, a winning cannot be established. That is, gaming machines that require skill in the timing of the stop operation (the high importance of technical intervention called “to push”) are currently mainstream.

Here, the above-mentioned internal lottery is performed in response to a player's start operation. Specifically, a random number is extracted when the player operates the start lever, and a combination corresponding to the value of the random number is determined as an internal winning combination (see, for example, Patent Document 1). The random number is extracted by extracting the random number at a timing when the start lever is operated from a random number generated (updated) within a certain numerical range within a certain numerical range.
JP 2001-170252 A

  However, as described above, if a random number within a certain range is generated every certain period by the random number generating means, the generation timing of the random number may be predicted by the player. Further, for example, when a game is played for a long time, random numbers may be extracted at the same timing in accordance with the operation of the start lever by the player. For this reason, if a random number in a certain range is generated for every certain period, there is a possibility that the change in the wave of the payout rate becomes monotonous. For this reason, for the player, the game is monotonous, and the interest may be reduced.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a gaming machine that can maintain the interest of the game by preventing the game from becoming monotonous.

  The present invention provides the following.

  (1) Symbol display means (for example, reels 3L, 3C, 3R, which will be described later) for displaying a plurality of symbols (for example, symbols 121 to 127 which will be described later), and a random number within a predetermined range (for example, a random width “16384” which will be described later) , “32768” and “65536” random number generation means (for example, a random number generator 36 to be described later), and a game start command signal for instructing the start of a unit game in response to an operation by the player ( For example, on the condition that a game start signal output means (for example, a start switch 6S described later) for outputting a game start command signal (to be described later) and a game start command signal from the game start signal output means have been detected, the random number Random number extraction means (for example, a sampling circuit 37 to be described later) for extracting random numbers generated by the generation means, and a game start command signal from the game start signal output means is detected. On the condition that the symbol display means changes the symbol displayed by the symbol display means (for example, stepping motors 49L, 49C, 49R described later, motor drive circuit 39, and main control circuit 71), and the random number Based on the random number extracted by the extracting means, a winning combination determining means (for example, a diagram described later) for determining at least one winning combination from a plurality of predetermined winning combinations (for example, BB, RB, and replay described later). And a stop command signal (for example, a stop command to be described later) for instructing stop of symbol variation performed by the symbol variation unit in response to an operation by the player. A stop signal output means (for example, a reel stop signal circuit 46 to be described later) and a stop command signal from the stop signal output means are detected. Further, based on the winning combination determined by the winning combination determining means, stop control means (for example, stepping motors 49L, 49C, 49R, which will be described later, motor driving) that performs stop control of symbol variation performed by the symbol varying means. A predetermined game value to the player based on the combination of the circuit 39 and the main control circuit 71) and the symbols stopped and displayed on the symbol display means (for example, combinations of symbols arranged along an effective line described later). A combination of a game value giving means (for example, means for performing step S27 in FIG. 15 to be described later, the main control circuit 71, etc.) and a symbol stopped and displayed by the symbol display means is a predetermined combination (for example, The combination of red 7-red 7-red 7 (to be described later) is relatively high in the expected value of the gaming value given to the player among a plurality of gaming states A bonus machine (for example, means for performing step S64 in FIG. 18 to be described later, main control circuit 71, etc.) for generating a bonus (for example, a BB gaming state to be described later). A gaming machine 1) that counts the number of times a unit game has been played from the end of the bonus until the next bonus is generated (for example, an inter-bonus game number counting means (for example, in FIG. 15 described later). A means for performing the process of step S31, the main control circuit 71, and the like, and a random number width changing means for changing the predetermined range according to the number of unit games counted by the bonus game number counting means (for example, described later) And a means for performing the process of step S91 in FIG. 20, a main control circuit 71, and the like.

  According to the gaming machine described in (1), since the inter-bonus game number counting means and the random number width changing means are provided, the next bonus is generated after the bonus counted by the inter-bonus game number counting means. The predetermined range (hereinafter referred to as “random number width”) that can be taken by the random number generated by the random number generating means can be changed according to the number of unit games performed so far. For this reason, it is more difficult for the player to predict what random numbers have been extracted compared to the case where random numbers are always generated with a constant random number width, and the game becomes monotonous for the player. To prevent and maintain the fun of the game.

  Since the bonus game number counting means and the random number width changing means are provided as described above, the random numbers generated by the random number generating means are different before and after the random number width is changed. That is, the random numbers extracted by the random number extraction means are different before and after changing the random number width, even when the player performs an operation at the same timing. For this reason, when a game is played for a long time, even if the probability of winning each winning combination is the same, it is possible to generate a wave of the payout rate and maintain the interest of the game.

  (2) In the gaming machine according to (1), a lottery table (for example, a probability lottery table in FIGS. 8 to 10 described later) that associates the plurality of winning combinations with the random numbers generated by the random number generation unit, A plurality of winning combinations are provided for each predetermined range, and the winning combination determining means determines the winning combination based on the random number extracted by the random number extracting means and a lottery table corresponding to the predetermined range. Gaming machine.

  According to the gaming machine described in (2), a plurality of lottery tables are provided for each predetermined range, that is, for each random number width. For this reason, before and after changing the random number width, even if the random numbers extracted by the random number extracting means are the same, different lottery tables are selected, so that the winning combination determined by the winning combination determining means is different. Cases can arise. Therefore, by providing various random number widths and providing multiple lottery tables for each of these various random number widths, it is possible to generate waves with various payout rates and prevent the game from becoming monotonous In this way, the entertainment of the game can be maintained.

According to the gaming machine of the present invention, since the inter-bonus game number counting means and the random number width changing means are provided, it is counted from the bonus game number counting means until the next bonus is generated after the bonus is ended. The predetermined range (hereinafter referred to as “random number width”) that can be taken by the random number generated by the random number generation means can be changed according to the number of unit games performed. For this reason, it is more difficult for the player to predict what random numbers have been extracted compared to the case where random numbers are always generated with a constant random number width, and the game becomes monotonous for the player. To prevent and maintain the fun of the game.
Since the bonus game number counting means and the random number width changing means are provided as described above, the random numbers generated by the random number generating means are different before and after the random number width is changed. That is, the random numbers extracted by the random number extraction means are different before and after changing the random number width, even when the player performs an operation at the same timing. For this reason, when a game is played for a long time, even if the probability of winning each winning combination is the same, it is possible to generate a wave of the payout rate and maintain the interest of the game.

  Furthermore, a motor drive circuit 39 that drives and controls the stepping motors 49L, 49C, and 49R, a hopper drive circuit 41 that drives and controls the hopper 40, a lamp drive circuit 45 that drives and controls the BET lamps 9a, 9b, and 9c, and the information display unit 18 A display unit driving circuit 48 that controls the driving of the CPU 31 is connected to the output unit of the CPU 31. Each of these drive circuits receives a control signal such as a drive command output from the CPU 31 and controls the operation of each actuator.

  The main input signal generating means for generating an input signal necessary for the microcomputer 30 to generate a control command includes a start switch 6S, a 1-BET switch 11, a 2-BET switch 12, a maximum BET switch 13, There are a C / P switch 14, a medal sensor 22S, a reel stop signal circuit 46, a reel position detection circuit 50, and a payout completion signal circuit 51.

  The start switch 6S, as a game start signal output means, detects the operation of the start lever 6 by the player and outputs a game start command signal for instructing the start of rotation of the reels 3L, 3C, 3R (start of unit game). . The medal sensor 22S detects a medal inserted into the medal slot 22 and outputs a predetermined signal. The reel stop signal circuit 46 detects the operation of each stop button 7L, 7C, 7R by the player as a stop signal output means, and outputs a stop command signal for instructing to stop the rotation of the corresponding reel 3L, 3C, 3R. To do.

  The reel position detection circuit 50 receives the pulse signal from the reel rotation sensor and supplies a signal for detecting the position of each reel 3L, 3C, 3R to the CPU 31. The payout completion signal circuit 51 counts the signal output from the medal detection unit 40S provided in the hopper 40, and when the number of medals paid out from the hopper 40 reaches the designated number, the payout of medals is performed. Outputs a signal to command completion.

Next, an outline of the operation of the main control circuit 71 configured as described above will be described.
First, in the circuit of FIG. 4, the random number generator 36 generates a random number belonging to a predetermined random number width at a predetermined cycle (see an interrupt process for generating a random number in FIG. 20 described later). The sampling circuit 37 extracts the random number generated by the random number generator 36 on the condition that the game start command signal output in response to the operation of the start lever 6 is detected. That is, the random number generated at any time by the random number generator 36 is extracted at the timing when the player operates the start lever 6 (see step S4 in FIG. 13 described later). The CPU 31 determines a winning combination based on the random number extracted by the sampling circuit 37 and a probability lottery table (see FIGS. 8 to 10 described later) stored in the ROM 32 (step in FIG. 13 described later). (See S6).

  Further, the CPU 31 sends a signal for rotating the reels 3L, 3C, 3R to the motor drive circuit 39 based on the game start command signal output at the timing when the player operates the start lever 6. The motor drive circuit 39 drives the stepping motors 49L, 49C, 49R according to the signal output from the CPU 31, and rotates the reels 3L, 3C, 3R. Thereby, the variation display of the symbol drawn on the outer peripheral surface of reel 3L, 3C, 3R is performed.

  After the rotation of the reels 3L, 3C, 3R is started, the number of drive pulses supplied to each of the stepping motors 49L, 49C, 49R is counted, and the counted value is written in a predetermined area of the RAM 33. From the reels 3L, 3C, 3R, reset pulses are obtained for each rotation, and these pulses are input to the CPU 31 via the reel position detection circuit 50. The count value of the drive pulse counted in the RAM 33 is cleared to “0” by the reset pulse thus obtained. As a result, the RAM 33 stores the count value corresponding to the rotational position within the range of one rotation for each of the reels 3L, 3C, 3R.

  A symbol table (not shown) is stored in the ROM 32 in order to associate the rotational positions of the reels 3L, 3C, and 3R with the symbols drawn on the outer peripheral surface of the reel. In this symbol table, the code number sequentially given for each fixed rotation pitch of each reel 3L, 3C, 3R with reference to the rotation position where the reset pulse is generated as described above is provided corresponding to each code number. A symbol code indicating the displayed symbol is associated with the symbol.

  Furthermore, a symbol combination table is stored in the ROM 32. In this symbol combination table, a symbol combination corresponding to a combination, a medal payout number corresponding to the symbol combination, and a determination code thereof are associated with each other. This symbol combination table is referred to when the left reel 3L, the center reel 3C, and the right reel 3R are stopped and when the display combination is confirmed after all the reels 3L, 3C, and 3R are stopped. Here, the display combination is a combination (established combination) corresponding to the symbol combinations arranged along the display line.

  Based on the lottery process (probability lottery process) based on the random number sampling, the CPU 31 operates the operation command signal sent from the reel stop signal circuit 46 at the timing when the player operates the stop buttons 7L, 7C, and 7R, and the selected stop. Based on the table, a signal for controlling the stop of the reels 3L, 3C, 3R is output to the motor drive circuit 39 to stop the rotation of the corresponding reel.

  Here, the stop table is a table that associates the timing at which the stop command signal is output with the position at which the reels 3L, 3C, 3R are stopped, and a plurality of stop tables are provided for each winning combination. The stop table is selected according to the winning combination determined in the probability lottery process.

  In the reels 3L, 3C, and 3R that are controlled to stop, if the combination of symbols displayed along the active line is in a stop mode indicating a winning combination, the CPU 31 supplies a payout command signal to the hopper drive circuit 41, The hopper 40 pays out medals. Here, the number of medals to be paid out by the hopper 40 depends on the combination of symbols that are stopped and the number of medals (BET number) bet on a unit game, as will be described in detail later with reference to FIG. Are predetermined.

  Further, when paying out medals from the hopper 40, the medal detection unit 40S detects the medals paid out from the hopper 40 and outputs a predetermined signal to the payout completion signal circuit 51. The payout completion signal circuit 51 counts signals from the medal detection unit 40S, and outputs a medal payout completion signal to the CPU 31 when the number of medals paid out from the hopper 40 reaches a designated number. As a result, the CPU 31 stops driving the hopper 40 via the hopper driving circuit 41 and ends the payout of medals.

  FIG. 6 shows the game condition of each game state, the transfer condition, and the game state of the transfer destination when the transfer condition is satisfied. In each gaming state, basically, the type of winning combination or its winning probability differs.

  The gaming state of the embodiment basically includes a general gaming state, a BB gaming state, an RB gaming state, a BB carryover state, and an RB carryover state. The BB carryover state and the RB carryover state are hereinafter referred to as “carryover state”. Further, the role carried over in this carryover state is hereinafter referred to as “carryover role”.

  The general game state is basically a game state in which an expected value of a so-called “play rate (game value given to a player for a unit game value bet on a game)” is smaller than “1”. . Further, it is a gaming state without a carryover role described later, and is the most disadvantageous gaming state for the player as compared with other gaming states.

  The BB gaming state is a gaming state configured by a BB general gaming state and an RB gaming state. Further, the BB gaming state is basically a gaming state constituted by a game in which the “actual accessory continuous actuating device related to the first type special accessory” is operating.

  The RB gaming state is basically a gaming state constituted by a game in which the “first type special character” is operating.

  The BB carryover state is a gaming state in which symbol combinations corresponding to BB are allowed to be arranged along the display line (BB establishment) over one or more games.

  The RB carryover state is a gaming state in which a combination of symbols corresponding to the RB is allowed along one or more games (establishment of RB).

  Here, as described later, when a specific condition is satisfied in the BB general gaming state, the RB gaming state is generated (shifted to the RB gaming state) without displaying the symbol combination corresponding to the RB. Also, when the RB wins internally during the BB gaming state (the BB general gaming state and the RB gaming state during the BB gaming state), the RB carryover state (the RB during BB carryover state) over one or more games in the BB gaming state ) And the symbol combination corresponding to RB is displayed, the gaming state is shifted from the RB carryover state (RB carryover state during BB) to the RB gaming state in the BB gaming state.

  Also, when the RB is won internally during the BB gaming state, or when the symbol combination corresponding to the RB is not displayed during the RB carryover state and a specific condition is satisfied, the current gaming state (for example, during BB The gaming state can be shifted from the (RB gaming state) to the RB gaming state during the BB gaming state. However, when the BB gaming state end condition is satisfied during the RB carryover state (RB during RB carryover state), the game state is shifted from the RB carryover state (RB during BB carryover state) to the general gaming state. Yes. On the other hand, when the RB is internally won during the general gaming state, the RB carryover state is entered and the RB is carried over.

  As shown in FIG. 6, the BB gaming state generation condition is establishment of BB. The game state transition condition is satisfied (satisfied) when the acquired number (for example, so-called “pure increase number” or “payout number”) is equal to or greater than a predetermined number (for example, 466), and the gaming state shifts to the general gaming state. To do.

  The condition for generating the RB gaming state during the general gaming state is establishment of RB. When one of the conditions that the predetermined number of times (for example, twelve times) the game is finished or the predetermined number of times (for example, eight times) is realized, the transition condition is satisfied, and the gaming state is Transition to the general gaming state.

  The condition for generating the carryover state is one of internal winning for BB, internal winning for RB, or internal winning for RB during the BB gaming state. The transition condition is established when the BB or RB is established, the BB gaming state is ended, or the RB gaming state is started in the BB gaming state, and the gaming state is BB gaming state, RB gaming state, or general Transition to the gaming state.

  The occurrence condition of the BB general gaming state is that the BB is established or that the RB gaming state is ended during the BB gaming state. When the BB gaming state ends or the RB gaming state starts during the BB gaming state, the transition condition is established, and the gaming state transitions to the general gaming state or the RB gaming state.

  The occurrence condition of the RB gaming state in the BB gaming state is that a specific condition is established in the BB gaming state or in the BB gaming state, or the RB gaming state in the BB gaming state or in the BB gaming state. RB is established inside. When one of the conditions that the predetermined number of times (for example, 12 times) the game is completed, the predetermined number of times (for example, 8 times) is realized, or the BB gaming state is ended is satisfied. The transition condition is satisfied, and the gaming state shifts to the general gaming state, the RB gaming state in the BB gaming state, or the BB general gaming state.

  With reference to FIG. 7, a combination of a combination, a symbol, and a payout number will be described.

  7 (1) is when the BET number (the number of medals bet on the game) is 1, FIG. 7 (2) is when the BET number is 2, and FIG. 7 (3) is when the BET number is 3. The combination of symbols, symbol combinations and the number of payouts are shown.

  BB is established by arranging “red 7-red 7-red 7” or “blue 7-blue 7-blue 7” along the active line (the display combination is BB). In addition, “Blue 7” and “Red 7”, which are symbol combinations of BB, are lottery with different flags.

  RB is established by arranging “BAR-BAR-BAR” along the effective line. In the BB general gaming state, RB is also established by arranging “Plum-Replay-Replay” along the active line.

  Replay is established by arranging “Replay-Replay-Replay” along the active line. When the replay 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 other words, the replay is a role that can be played without newly inserting a medal when it is established.

  In addition, the combinations of symbols that form the “watermelon small part”, “plum small part”, “upper and lower cherry small part”, and “medium cherry small part” are as illustrated.

In the general gaming state, BB (red 7), BB (blue 7), RB, replay, watermelon small part, plum small part, top and bottom cherry small part, and middle cherry small part may be won internally. .

  Here, when BB (red 7) is hit internally (when BB (red 7) is carried over), “red 7-red 7-red 7” is allowed to line up along the active line. When BB (blue 7) is hit internally (when BB (blue 7) is carried over), “blue 7-blue 7-blue 7” is allowed to line up along the active line.

  (2) in FIG. 8 shows a BB general gaming state probability random determination table provided corresponding to the random number width of “16384”. In the BB general gaming state, there are cases where RB1, RB2, replay, watermelon small part, plum small part, top and bottom cherry small part, and medium cherry small part are internally won.

  Here, when RB1 is won internally (when RB1 is carried over), “BAR-BAR-BAR” is allowed to line up along the active line. When RB2 is won internally (when RB2 is carried over), “Plum-Replay-Replay” is allowed to line up along the active line.

  (3) of FIG. 8 shows an RB gaming state probability lottery table provided corresponding to the random number width of “16384”. In this RB gaming state, there are cases where a watermelon, a plum, a cherry top and a cherry cherry, and a medium cherry are played internally.

A lottery table and a carryover state probability lottery table are shown. Each of the probability lottery tables of (1) to (4) in FIG. 9 has twice the random number width and the random number range as compared to the probability lottery tables of (1) to (4) in FIG. Yes.

  (1) to (4) in FIG. 10 respectively show a general gaming state probability lottery table, a BB general gaming state probability lottery table, and an RB gaming state probability provided corresponding to a random number width of “65536”. A lottery table and a carryover state probability lottery table are shown. Each of the probability lottery tables of (1) to (4) in FIG. 10 has a random number width and a random number range four times that of the probability lottery tables of (1) to (4) in FIG. Yes.

  The random number width selection table will be described with reference to FIG.

  The random number width selection table includes information on a random number width that is set according to the number of BB inter-game games, which is the number of unit games performed from the end of the BB game state to the occurrence of the next BB game state. Yes. Specifically, each time the number of games between BB games increases by 200, a different random number width is associated. For example, when the number of games between BB games is 0 to 200, information with a random number width of “16384” is stored. Further, when the number of games between BB games is between 201 and 400, information having a random number width of “32768” is stored. Further, when the number of games between BB games is 401 to 600, information with a random number width of “65536” is stored. Then, when the number of games between BB games is between 601 and 800, information with a random number width of “16384” is stored again.

  The jump table will be described with reference to FIG.

  The jump table includes information on processing to be performed according to the type of command received when a command (information or command) transmitted by the main control circuit 71 is received. Specifically, information on 11 types of processing to be executed corresponding to the “head data” of the command transmitted by the main control circuit 71 is stored. The main control circuit 71 transmits data (information) composed of “4 bytes” to “8 bytes” to the sub control circuit 72 as one command, but the “first data” is the “first byte”. Data is shown.

  The “initialization process” is a process for initializing the work RAM 84 and the like. “Demo display process” is a process of displaying a demo image on the display screen 5a. The “game medal insertion process” is a process performed in response to a “BET operation”. The “game start process” is a process performed when the start lever 6 is operated. The “reel stop process” is a process performed when any one of the stop buttons 7L, 7C, 7R is operated. The “all reel stop process” is a process that is performed when the “third stop operation” is performed.

  The “winning process” is a process performed based on the success or failure of the combination. The “bonus game state change instruction process” is a process for changing the game state information to indicate “BB game state” or “RB game state” when a bonus (BB, RB) is won. The “bonus game end state process” is a process for changing the game state information to the “general game state” at the end of the “BB game state” or the “RB game state”. The “error effect instruction process” is a process for displaying, on the display screen 5a, an image for notifying the malfunction when a malfunction such as the medals in the hopper 40 becoming empty occurs. The “sound effect instruction process” is a process for executing an effect by “sound”.

  The control operation of the main control circuit 71 will be described with reference to the main flowcharts shown in FIGS.

  First, the CPU 31 performs initialization at the start of the game (step S1). Specifically, the contents stored in the RAM 33 are initialized, the communication data is initialized, the random number counter is initialized, the BB intergame number counter is initialized. The random number counter and the BB game number-of-games counter are composed of registers in the CPU 31. The value of the random number counter becomes “0” when initialized, and is used in an interrupt process for generating a random number described later with reference to FIG. Also, the value of the BB inter-game number counter becomes “0” when initialized, and the control operation of the main control circuit 71 described later with reference to FIG. 15 and later described with reference to FIG. This is used in the probability lottery processing to be performed and the interrupt processing for generating a random number which will be described later with reference to FIG.

  Subsequently, a predetermined storage content (information of a predetermined storage area (for example, an area for storing an internal winning combination)) in the RAM 33 at the end of the game is deleted (step S2), and the process proceeds to step S3. Specifically, the data in the writable area of the RAM 33 used in the previous game is erased, the parameters necessary for the next game are written in the write area of the RAM 33, the start address of the sequence program of the next game is specified, etc. I do.

  In step S3, a medal insertion / start check process described later with reference to FIG. 16 is performed, and the process proceeds to step S4. In step S4, a random number for lottery is extracted, and the process proceeds to step S5. The random numbers extracted in this process are used in the probability lottery process described later with reference to FIG.

  In step S5, a game state monitoring process is performed, and the process proceeds to step S6. In step S6, a probability lottery process described later with reference to FIG. 17 is performed, and the process proceeds to step S7. In step S7, stop table selection processing for selecting a stop table based on an internal winning combination is performed, and the process proceeds to step S8.

  In step S8, a start command is set, and the process proceeds to step S9. The start command includes information such as a gaming state and an internal winning combination, and is transmitted to the sub-control circuit 72. In step S9, it is determined whether 4.1 seconds have elapsed since the previous game started. When this determination is YES, the process proceeds to step S11, and when NO, the process proceeds to step S10.

  In step S10, a game start waiting time digest process (wait process) is performed, and the process proceeds to step S11. Specifically, a process of invalidating an input based on an operation for starting a player's game until a predetermined time (for example, a predetermined second (eg, 4.1 seconds)) has elapsed since the start of the previous game. I do. In step S11, a game monitoring timer is set, and the process proceeds to step S12. This game monitoring timer includes an automatic stop timer for automatically stopping the reels 3L, 3C, 3R regardless of the stop operation of the player's stop buttons 7L, 7C, 7R.

  In step S12, the start of rotation of all reels is requested, and the process proceeds to step S13. In step S13, a reel stop permission command is set, and the process proceeds to step S14 in FIG.

  In step S14, it is determined whether or not the stop switch is “ON”, that is, whether any one of the stop buttons 7L, 7C, and 7R has been operated. When this determination is YES, the process proceeds to step S16, and when NO, the process proceeds to step S15. In step S15, it is determined whether or not the value of the automatic stop timer is “0”. When this determination is YES, the process proceeds to step S16, and when NO, the process proceeds to step S14.

  In step S16, the number of sliding frames is determined, and the process proceeds to step S17. In step S17, the process waits for the reels 3L, 3C, 3R corresponding to the stopped stop buttons 7L, 7C, 7R to rotate by the number of sliding frames determined in step S16, and then proceeds to step S18.

  In step S18, the reel rotation is requested to stop, and the process proceeds to step S19. In step S19, a reel stop command is set, and the process proceeds to step S20. In step S20, it is determined whether or not all reels have stopped. When this determination is YES, the process proceeds to step S21 in FIG. 15, and when NO, the process proceeds to step S14.

  In step S21 of FIG. 15, display combination search processing is performed, and the process proceeds to step S22. In the display combination search process, a flag for identifying a display combination (a winning combination) is set based on the pattern stop mode of the display windows 4L, 4C, and 4R. In step S22, it is determined whether or not there is an illegal hit, that is, whether or not there is a mismatch between the internal winning combination and the display combination. When this determination is YES, the process proceeds to step S23, and when NO, the process proceeds to step S24. In step S23, an illegal error is displayed. In this case, the game is canceled.

  In step S24, a display combination command including display combination information is set, and the process proceeds to step S25. In step S25, it is determined whether or not the payout number corresponding to the display combination is “0”. When this determination is YES, the process proceeds to step S27, and when NO, the process proceeds to step S26. In step S26, medals are stored (credit) or paid out, and the process proceeds to step S27. In step S27, a payout end command is set, and the process proceeds to step S28.

  In step S28, it is determined whether or not the RB operating flag or the BB operating flag is “ON”. When this determination is YES, the process proceeds to step S30, and when NO, the process proceeds to step S29. The RB operating flag is information for identifying whether or not the RB gaming state is set, and is “ON” when in the RB gaming state, and “OFF” when not in the RB gaming state. The BB operating flag is information for identifying whether or not the player is in the BB gaming state, and is “ON” when in the BB gaming state, and “OFF” when not in the BB gaming state. Therefore, in the RB gaming state in BB, both flags are “ON”. In the general RB gaming state, the RB operating flag is “ON” and the BB operating flag is “OFF”.

  In step S29, an RB / BB operation check process described later with reference to FIG. 18 is performed, and the process proceeds to step S31. In step S30, RB and BB end check processing described later with reference to FIG. 19 is performed, and the process proceeds to step S31. In step S31, the inter-game number-of-games counter is incremented by “1”, and the process proceeds to step S2 in FIG.

  The medal insertion / start check process will be described with reference to FIG.

  First, the CPU 31 determines whether or not 30 seconds have elapsed since the end of the previous game, that is, after all the reels 3L, 3C, 3R stopped (step S41). When this determination is YES, the process proceeds to step S42, and when this determination is NO, the process proceeds to step S43. In step S42, a demonstration display command is set, and the process proceeds to step S43.

  In step S43, it is determined whether or not there is a request for automatic insertion of medals, that is, whether or not a replay (replay) win has been established in the previous game. When this determination is YES, the process proceeds to step S44, and when NO, the process proceeds to step S45. In step S44, medals for the insertion request are automatically inserted, and the process proceeds to step S46. In step S45, it is determined whether or not there is an input from the medal sensor 22S or the BET switches 11, 12, and 13. When this determination is YES, the process proceeds to step S46, and when it is NO, the process proceeds to step S41.

  In step S46, it is determined whether or not there is an input from the start switch 6S based on the operation of the start lever 6. When this determination is YES, the process proceeds to step S4 of FIG. 13, and when NO, step S46 is repeated.

  The probability lottery process will be described with reference to FIG.

  First, the CPU 31 determines whether or not it is in the RB gaming state or the BB general gaming state (step S51). When this determination is YES, the process proceeds to step S52, and when this determination is NO, the process proceeds to step S53. In step S52, an internal winning combination is determined based on the probability lottery table for the RB gaming state or the BB general gaming state corresponding to the value of the BB intergame number-of-games counter, and the process proceeds to step S56. Specifically, the probability lottery table shown in FIG. 8 and the probability lottery table shown in FIG. 9 each time the value of the BB intergame number counter increases by “200”, that is, every time the BB intergame count increases by 200. The probability lottery table for the RB gaming state or the BB general gaming state used in the order of the probability lottery table shown in FIG. 10 is changed to determine the internal winning combination. For example, when the value of the BB inter-game number counter is “0” to “200”, that is, between the BB inter-game numbers is 0 to 200, the RB game state shown in (3) of FIG. Alternatively, the internal winning combination is determined based on the probability lottery table for the BB general gaming state in (2) of FIG. In addition, when the value of the BB inter-game number counter is “201” to “400”, that is, between the BB inter-game numbers is 201 to 400, it is for the RB gaming state of (3) in FIG. Alternatively, the internal winning combination is determined based on the probability lottery table for the BB general gaming state in (2) of FIG. Also, when the value of the BB inter-game number counter is “401” to “600”, that is, between the BB inter-game numbers is 401 to 600, it is for the RB gaming state in (3) of FIG. Alternatively, the internal winning combination is determined based on the probability lottery table for the BB general gaming state in (2) of FIG. When the value of the BB game count is “601” to “800”, that is, when the BB game count is 601 to 800, the RB game shown in FIG. An internal winning combination is determined based on the probability lottery table for the state or for the BB general gaming state in (2) of FIG.

  In step S53, it is determined whether or not it is a carryover state. When this determination is YES, the process proceeds to step S54, and when it is NO, the process proceeds to step S55. In step S54, an internal winning combination is determined based on the carry-over state probability lottery table corresponding to the value of the BB inter-game number-of-games counter, and the process proceeds to step S56. Specifically, the probability lottery table shown in FIG. 8 and the probability lottery table shown in FIG. 9 each time the value of the BB intergame number counter increases by “200”, that is, every time the BB intergame count increases by 200. The probability lottery table for the RB gaming state or the BB general gaming state used in the order of the probability lottery table shown in FIG. 10 is changed to determine the internal winning combination. For example, when the value of the BB game number-of-games counter is “0” to “200”, that is, between BB games is 0-200 times, the value for the carryover state in (4) of FIG. An internal winning combination is determined based on the probability lottery table. In addition, when the value of the BB inter-game number counter is “201” to “400”, that is, between the BB inter-game number of times is 201 to 400, it is for the carryover state in FIG. 9 (4). An internal winning combination is determined based on the probability lottery table. In addition, when the value of the BB inter-game number counter is between “401” and “600”, that is, between the BB inter-game number of games is between 401 and 600, it is for the carryover state in (4) of FIG. An internal winning combination is determined based on the probability lottery table. When the value of the BB inter-game number counter is between “601” and “800”, that is, between the BB inter-game number of games from 601 to 800, the carryover state of (4) in FIG. The internal winning combination is determined based on the probability lottery table.

  In step S55, an internal winning combination is determined based on the probability lottery table for the general gaming state according to the value of the unit game number counter, and the process proceeds to step S56. Specifically, the probability lottery table shown in FIG. 8 and the probability lottery table shown in FIG. 9 each time the value of the BB intergame number counter increases by “200”, that is, every time the BB intergame count increases by 200. The probability lottery table for the RB gaming state or the BB general gaming state used in the order of the probability lottery table shown in FIG. 10 is changed to determine the internal winning combination. For example, when the value of the BB inter-game number counter is “0” to “200”, that is, between the BB inter-game number of times is 0 to 200, it is for the general gaming state of (1) in FIG. The internal winning combination is determined based on the probability lottery table. In addition, when the value of the BB inter-game number counter is “201” to “400”, that is, between the BB inter-game number of times is 201 to 400, for the general gaming state of (1) in FIG. The internal winning combination is determined based on the probability lottery table. Further, when the value of the BB inter-game number counter is between “401” and “600”, that is, between the BB inter-game number of games is between 401 and 600, it is for the general gaming state of (1) in FIG. The internal winning combination is determined based on the probability lottery table. When the value of the BB game count is between “601” and “800”, that is, when the BB game count is between 601 and 800, the general game shown in FIG. An internal winning combination is determined based on the state probability lottery table.

  In step S56, it is determined whether or not the internal winning combination is RB or BB. When this determination is YES, the process proceeds to step S57, and when NO, the process proceeds to step S7 in FIG. In step S57, a carryover combination is set based on the internal winning combination, and the process proceeds to step S7 in FIG.

  With reference to FIG. 18, the RB / BB operation check process will be described.

When this determination is YES, the process proceeds to step S62, and when it is NO, the process proceeds to step S63. In step S62, RB operation processing is performed, and the process proceeds to step S2 in FIG.

  In step S63, it is determined whether or not the display combination is BB. When this determination is YES, the process proceeds to step S64, and when it is NO, the process proceeds to step S2 in FIG. In step S64, BB operation processing is performed, and the process proceeds to step S2 in FIG. Specifically, the BB operating flag is set to “on”.

  With reference to FIG. 19, the RB and BB end check processing will be described.

  First, the CPU 31 determines whether or not the RB operating flag is “ON” (step S71). When this determination is YES, the process proceeds to step S72, and when it is NO, the process proceeds to step S76. In step S72, information on the number of RB games (number of games in the RB game state) and the number of display times is updated, and the process proceeds to step S73.

  In step S73, it is determined whether or not it is the end of the RB gaming state. When this determination is YES, the process proceeds to step S74, and when this determination is NO, the process proceeds to step S2 in FIG. In step S74, processing at the end of RB is performed, and the process proceeds to step S75. In step S75, it is determined whether or not the BB operating flag is “ON”. When this determination is YES, the process proceeds to step S76, and when NO, the process proceeds to step S2 in FIG.

  In step S76, information on the number of medals paid out in the BB gaming state is updated, and the process proceeds to step S77. In step S77, it is determined whether or not the BB gaming state has ended. When this determination is YES, the process proceeds to step S78, and when this determination is NO, the process proceeds to step S79. In step S78, processing at the end of BB is performed, and the process proceeds to step S2 in FIG. Specifically, the BB operating flag is set to “off”, the BB intergame number counter is initialized, and the BB intergame number counter is set to “0”.

  In step S79, it is determined whether or not the display combination is RB. When this determination is YES, the process proceeds to step S80, and when NO, the process proceeds to step S2 in FIG. In step S80, RB operation processing is performed, and the process proceeds to step S2 in FIG.

  An interrupt process for generating a random number will be described with reference to FIG. The interrupt process for generating the random number is performed, for example, every 224 μsec while the control operation of the main control circuit 71 shown in FIGS. 13 to 15 is being performed.

  First, the CPU 31 sets a random number width based on the value of the BB intergame number-of-games counter and the random number width selection table (step S91). Specifically, for example, when the value of the BB game number-of-games counter is “0” to “200”, that is, between BB games is 0-200 times, the random number width is “16384”. Set to. The random number width is set to “32768” while the value of the inter-game number of games counter is “201” to “400”, that is, between BB games is from 201 to 400 times. The random number width is set to “65536” when the value of the counter number of games between BB games is “401” to “600”, that is, the number of games between BB games is 401 to 600 times.

  Subsequently, in step S92, the random number counter is incremented by “1”, and the process proceeds to step S93. In step S93, it is determined whether or not the set random number width is “16384”. If this determination is YES, the process moves to a step S94, and if NO, the process moves to a step S95. In step S94, the value of the random number counter is corrected to “0” to “16383”, and the interrupt process for generating a random number is terminated. Specifically, if the value of the random number counter is a value excluding “0” to “16383”, the value of the random number counter is set to “0”.

  In step S95, it is determined whether or not the set random number width is “32768”. When this determination is YES, the process proceeds to step S96, and when NO, the process proceeds to step S97. In step S96, the value of the random number counter is corrected to “0” to “32767”, and the interrupt process for generating a random number is terminated. Specifically, if the value of the random number counter is a value excluding “0” to “32767”, the value of the random number counter is set to “0”.

  In step S97, the value of the random number counter is corrected to “0” to “65535”, and the interrupt process for generating a random number is terminated. Specifically, if the value of the random number counter is a value excluding “0” to “65535”, the value of the random number counter is set to “0”.

  The gaming machine 1 configured as described above has the following effects.

  According to the gaming machine 1, it is generated by the random number generator 36 in accordance with the number of unit games (the number of games between BB gaming states) that have been performed from the end of the BB gaming state until the next BB gaming state is generated. The random number range that can be taken is changed. For this reason, it is more difficult for the player to predict what random numbers have been extracted compared to the case where random numbers are always generated with a constant random number width, and the game becomes monotonous for the player. To prevent and maintain the fun of the game.

  In addition, for example, when a random number is continuously generated by updating numerical values included in a certain random number width in ascending order at a certain cycle, random numbers having the same value are always generated at the same timing. In such a case, for example, if the player performs a start operation at the same timing, the same random number may be extracted.

  However, according to the gaming machine 1, since the random number width of the random number generator 36 is changed according to the number of games between the BB gaming states, the player can start operation at the same timing before and after the random number width is changed. Even when the above is performed, the random numbers extracted by the sampling circuit 37 are different. For this reason, when a game is played for a long time, even if the probability of winning each winning combination is the same, it is possible to generate a wave of the payout rate and maintain the interest of the game.

  Further, according to the gaming machine 1, a plurality of probability lottery tables are provided for each random number width of the random number generator 36. For this reason, before and after changing the random number width, even when the random numbers extracted by the sampling circuit 37 are the same, since different probability lottery tables are selected, the winning combinations determined may differ. obtain. Therefore, by providing various random number widths and providing a plurality of probability lottery tables for each of these various random number widths, it becomes possible to generate waves of various payout rates, and the game becomes monotonous for the player. To prevent and maintain the fun of the game.

  As mentioned above, although the Example was described, this invention is not limited to this.

  In the above embodiment, the random number generator 36 and the sampling circuit 37 are provided as the random number generation means and the random number extraction means. However, the present invention is not limited to this. For example, random number generation and extraction may be executed in the microcomputer 30, that is, on the operation program of the CPU 31. In that case, the random number generator 36 and the sampling circuit 37 can be omitted, but may be provided for backup.

  In the above embodiment, the random numbers are generated by updating (counting up) the numerical values belonging to the predetermined random number width in ascending order by 1 every predetermined period. However, the present invention is not limited to this. For example, a random number may be generated by updating a numerical value belonging to a predetermined random number width based on a recurrence formula determined in advance for each predetermined period.

  Further, in the above embodiment, in order to briefly explain the features of the present invention, the configuration relating to the gameability of the gaming machine such as the type of the combination is simplified, but the present invention is not limited to this. Specifically, in the gaming machine of the above embodiment, as the types of the set roles, “BB (red 7)”, “BB (blue 7)”, “RB”, “Replay”, “Watermelon small role” "," Plum's small part "," Cherry's small part ", etc. are set. However, the present invention is not limited to these, and more types of combinations may be set.

  Moreover, in the said Example, as a bonus, the 1st type special accessory (regular bonus, RB) and the 1st type special agent continuation apparatus (big bonus, BB) which operate | moves this 1st type special bonus continuously. However, the present invention is not limited to this. For example, a second-type special combination (challenge game, CG) and a second-type combination continuous operation device (challenge bonus, CB) for continuously operating the second-type special combination may be provided. .

  In the above embodiment, the random number width is changed every time the unit game is performed 200 times after the end of the BB gaming state. For example, the random number width may be changed every 1000 times for the unit game after the end of the BB game state. In addition, an operation unit that can be operated by a game hall employee or the like is provided as input signal generation means for generating an input signal necessary for the microcomputer 30 to generate a control command, and the BB game when changing the random number width is provided. The number of unit games after the end of the state may be set. By doing in this way, it becomes possible for an employee of a game hall or the like to generate a wave of the game play ratio depending on the situation of the game play rate.

  Further, the present invention can be applied to other gaming machines such as pachinko gaming machines and pachilots in addition to the gaming machine 1 as in the present embodiment. Furthermore, the game can be executed by applying the present invention even in a game program in which the above-described operation of the gaming machine 1 is simulated for a home game machine. In that case, a CD-ROM, FD (flexible disk), or any other recording medium can be used as a recording medium for recording the game program.
