  As shown in the figure, in the RB gaming state, the winning probability of the bell is 10 of the winning probability in each probability lottery table shown in FIGS. 9 (c), 10 (c) and 11 (c). It is doubled, and the small part of Bell is determined with high probability.

  FIGS. 13A and 13B are diagrams conceptually showing a bonus operation time table referred to by the main CPU 64 when the bonus is operated. FIG. 13A shows a BB operation table, and FIG. 13B shows an RB operation table. ing.

  Each operation table is composed of a storage area and data stored in the storage area, and is used in bonus operation check processing (see FIG. 14, S27) described later.

  The storage area of the operating flag in the BB operating table stores the data of the operating flag of the BB indicating that the BB is operating and the gaming state is in the BB gaming state. Stores the maximum number of medals that can be paid out after the BB operating flag is turned on until it is cleared. In the present embodiment, the maximum number data is set to “345”.

  In the operating flag storage area of the RB operating time table, RB operating flag data indicating that the RB is operating and the gaming state is in the RB gaming state is stored. In addition, in the storage area for the possible number of games, data on the maximum number of games that can be performed from when the RB operating flag is turned on until it is cleared is stored. Stores the maximum number-of-winnings data that can establish a winning in which medals are paid out after the RB operating flag is turned on and cleared. In the present embodiment, the maximum game number data and the maximum winning number data are set to “12” and “8”, respectively.

  The data in each table is read from the program ROM 65 and stored in the control RAM 66 at the address indicated in the storage area during the game.

  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. 14). Specifically, the contents stored in the control RAM 66 are initialized, the communication data is initialized, and the like. Subsequently, the designated RAM area of the control RAM 66 at the end of the previous game is cleared (S2). Specifically, data deletion of the area used in the previous game, writing of parameters necessary for the next game, designation of the start address of the sequence program of the next game, and the like are performed.

  Next, the main CPU 64 performs a maximum inserted number determination process described later (S3), and subsequently performs a medal insertion / start check process described later (S4). Subsequently, the main CPU 64 extracts the random numbers for lottery generated by the random number generator 69 by the sampling circuit 70 (S5). Next, the main CPU 64 performs a gaming state monitoring process described later (S6), performs a probability lottery process described later (S7), and subsequently performs a winning combination determination process for stopping (S8). In the stop winning combination determination process, the winning combination for stop used for the stop control of each reel 2 to 4 is determined based on the winning combination determined in the probability lottery process of S7.

  Next, the main CPU 64 sets a start command in the transmission data storage area of the control RAM 66 and transmits it to the sub control board 62 side via the sub control unit communication port 79 (S9). The start command is a command including information such as the gaming state identified in S6 and the winning combination determined in the probability lottery process in S7. Subsequently, the main CPU 64 determines whether or not 4.1 seconds have elapsed since the start of the previous reel rotation (S10). When this determination is “No”, the wait process (S11) 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 each reel 2 to 4) is performed. When 4.1 seconds have passed since the start of the previous reel rotation, the main CPU 64 sets a game monitoring timer in the control RAM 66 (S12). This game monitoring timer is a timer for monitoring the time of each unit game, and is used for automatic stop for automatically stopping each reel 2 to 4 without the player's stop operation of the stop buttons 31 to 33. This timer is also included.

  When the process of S12 is completed, the main CPU 64 requests the start of rotation of all the reels 2 to 4 (S13), and starts the rotation of all the reels 2 to 4. Subsequently, a reel stop permission command is set in the transmission data storage area of the control RAM 66 and transmitted to the sub control board 62 side via the sub control unit communication port 79 (S14). 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 (S15). If this determination is “No” without any of the stop buttons 31 to 33 being operated, it is subsequently determined whether or not the value of the automatic stop timer is “0” (S16). When this determination is “No”, the process returns to S15, and the processes of S15 and S16 are repeated.

  When one of the stop buttons 31 to 33 is operated and the determination of S15 becomes “Yes”, or when the value of the automatic stop timer becomes “0” and the determination of S16 becomes “Yes”, The main CPU 64 performs a sliding frame number determination process (S17). In the sliding frame number determination process, the number of sliding frames is determined from 0 frame to 4 frames based on the winning combination and the carryover combination. Here, the number of sliding symbols indicates the number of symbols to be moved from when any one of the stop buttons 31 to 33 is operated until the reel corresponding to the operated stop button 31 to 33 stops. , Sometimes referred to as “number of pull-ins”.

  Next, 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 for the number of sliding frames determined in S17 (S18), and then the stop button 31 that has been stopped. The rotation stop of the reels 2 to 4 corresponding to .about.33 is requested (S19). Next, the main CPU 64 sets a reel stop command in the transmission data storage area of the control RAM 66, and transmits it to the sub control board 62 side via the sub control unit communication port 79 (S20). The reel stop command is a command including information that can identify one of the stopped reels 2 to 4, information that can identify the type of symbol displayed by the stopped reel on a predetermined activated pay line, and the like. is there.

  Next, the main CPU 64 determines whether or not all reels are stopped (S21). If this determination is “No”, the process returns to S15, and the processes of S15 to S21 described above are repeated. On the other hand, when all the reels 2 to 4 are stopped and the determination in S21 is “Yes”, the main CPU 64 performs a display combination specifying process (S22). In this display combination specifying process, with reference to the set value of the active line counter (see S56 in FIG. 16), the type of combination of symbols that are actually displayed on the activated pay line, that is, the display combination The winning combination determined by the probability lottery process (see FIG. 14, S7) is matched. Then, it is determined whether there is an error in the display combination displayed on the activated pay line and it corresponds to an illegal hit. If the determination result corresponds to an illegal hit, the payout number display portion is displayed. 20 and the liquid crystal display 22 display illegal errors. If the display combination is normal and not an illegal hit, then the main CPU 64 sets the display combination command in the transmission data storage area of the control RAM 66 and the sub control board 62 side via the sub control unit communication port 79. (S23). The display combination command is a command including information such as a combination type of symbols that are actually displayed on the activated pay line.

  Next, the main CPU 64 performs medal payout processing (S24). In the medal payout process, if a game is being played with credit, the number of stored medals displayed on the stored number display unit 16 is increased by the number of medals paid out by winning, and the medal slot 8 is displayed. If a game is being performed with the medal being inserted, the number of medals won by winning is paid out to the medal tray 37. Subsequently, the main CPU 64 sets a payout end command including information on the completion of the payout process in the transmission data storage area of the control RAM 66 and transmits it to the sub control board 62 side via the sub control unit communication port 79 ( S25).

  Next, the main CPU 64 refers to the control RAM 66 to determine whether or not the BB operating flag or the RB operating flag is “ON” (S26). If this determination is “No” and none of the flags is “on”, a bonus operation check process described later is performed (S27). On the other hand, if the determination in S26 is "Yes" and at least one of the operating flags is "on", a bonus end check process described later is performed (S28). When the process of S27 or S28 ends, the game process returns to S2 and the next new unit game is started.

  Next, with reference to FIG. 15, the maximum inserted number determination process performed in FIGS. 14 and S3 will be described.

  In this maximum insertion number determination process, first, the main CPU 64 refers to the control RAM 66 to determine whether or not the RB operation flag is “ON” (see S41 in FIG. 15). When RB or SRB is specified as the display combination in the unit game up to the previous time and the determination of S41 is “Yes”, the main CPU 64 determines the maximum inserted number as “1” and stores the maximum inserted number in the control RAM 66. “1” is set in the area (S42). On the other hand, when the RB operating flag is “off” and the determination in S41 is “No”, the main CPU 64 refers to the control RAM 66 to determine whether or not the BB operating flag is “on” ( S43). When the current gaming state is the general gaming state or the internal winning state and the determination in S43 is “No”, the maximum inserted number determination process ends. Further, when the BB operating flag is “ON” and the determination of S43 is “Yes”, that is, in the BB general gaming state, the main CPU 64 is based on the maximum inserted number lottery table (see FIG. 8). A lottery is performed, and the maximum inserted number determined by the lottery is set in the maximum inserted number storage area of the control RAM 66 (S44).

  Next, with reference to FIG. 16, the medal insertion / start check process performed in FIGS. 14 and S4 will be described.

  In the medal insertion / start check process, first, the main CPU 64 performs a medal insertion permission process (see S51 in FIG. 16). In this medal insertion permission process, if a game is being played with credit, the operation of the stored medal insertion buttons 26 to 28 is validated, and a game is being performed by inserting a medal into the medal insertion slot 8. If there is, processing for enabling medal insertion into the medal insertion slot 8 is performed. Subsequently, the main CPU 64 performs a medal sensor / bet switch check process (S52). In this process, it is checked whether the inserted medal sensor 8S detects a medal inserted from the medal slot 8, or whether the stored medal insertion switches 26S-28S detect the operation of the stored medal insertion buttons 26-28. To do. Subsequently, based on the check of S52, the main CPU 64 determines whether the inserted medal sensor 8S detects a inserted medal or whether the stored medal insertion switches 26S to 28S detect the operation of the stored medal insertion buttons 26 to 28. A determination is made (S53). If this determination is “Yes”, the main CPU 64 updates the inserted number counter (S54), and then sends a bet command including information such as the updated inserted number counter value to the control RAM 66. The data is set in the transmission data storage area and transmitted to the sub control board 62 side via the sub control unit communication port 79 (S55).

  Next, the main CPU 64 validates the number of winning lines corresponding to the value of the inserted number counter, and sets the value of the effective line counter to the number of validated winning lines (S56). Subsequently, the main CPU 64 determines whether or not the value of the maximum insertion number determined in the maximum insertion number determination process (see S3 in FIG. 14) is the same as the value of the insertion number counter updated in S54 (S57). ). When the number of medals equal to the maximum inserted number is inserted and the determination in S57 is “Yes”, the main CPU 64 performs a medal insertion prohibition process (S58). In the medal insertion prohibition process, the main CPU 64 performs a process for prohibiting the addition of the insertion number counter and turns off the insert lamp 21 to notify the player that the medal insertion prohibition is prohibited. For a medal additionally received after the medal insertion prohibition process, the value of the credit counter is added in the process of S54.

  When the determination in S53 is “No” and the inserted medal sensor 8S or the stored medal insertion switches 26S to 28S are not detected, the determination in S57 is “No” and the value of the inserted number counter is smaller than the value of the maximum inserted number. When the medal insertion prohibition process of S58 is performed, the main CPU 64 subsequently determines whether or not the value of the insertion number counter is 1 or more (S59). If no medal has been inserted and the determination in S59 is “No”, the process returns to S52, and the above-described processes of S52 to S59 are repeated. On the other hand, if the determination in S59 is “Yes”, then the main CPU 64 determines whether or not the start lever 30 is operated and the start switch 30S is “on” (S60). If this determination is “No”, the process returns to S52, and the processes of S52 to S60 described above are repeated. On the other hand, when the determination in S60 is “Yes”, the medal insertion / start check process ends.

  Next, the gaming state monitoring process performed in FIGS. 14 and S6 will be described with reference to FIG.

  In this gaming state monitoring process, first, the main CPU 64 refers to the control RAM 66 to determine whether or not the RB operating flag is “ON” (see S81 in FIG. 17). When this determination is “Yes”, the main CPU 64 sets the gaming state to the RB gaming state (S82). If the determination in S81 is “No”, then the main CPU 64 refers to the control RAM 66 to determine whether or not the BB operating flag is “on” (S83). When this determination is “Yes”, the main CPU 64 sets the gaming state to the general gaming state during BB (S84). If the determination in S83 is “No”, then the main CPU 64 refers to the control RAM 66 to determine whether a carryover combination is set (S85). When this determination is “Yes”, the main CPU 64 sets the gaming state to the BB internal winning state or the RB internal winning state according to the carryover combination (S86). If the determination in S85 is “No”, the main CPU 64 sets the gaming state to the general gaming state (S87). When the gaming state is set in S82, S84, S86 or S87, the gaming state monitoring process ends.

  Next, the probability lottery process performed in FIGS. 14 and S7 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 a general gaming state during BB (see S91 in FIG. 18). If this determination is “Yes”, one of the tables in the BB general gaming state probability lottery table shown in FIGS. 11A to 11C is selected according to the value of the inserted number counter, The winning combination is determined based on the selected table (S92). On the other hand, when the determination in S91 is “No”, the main CPU 64 determines whether or not the gaming state is the RB gaming state (S93). If this determination is “Yes”, the winning combination is determined based on the RB gaming state probability lottery table shown in FIG. 12 (S94). On the other hand, if the determination in S93 is “No”, the main CPU 64 determines whether or not the gaming state is an internal winning state (S95). When this determination is “Yes”, one of the tables in the internal winning state probability lottery table shown in FIGS. 10A to 10C is selected and selected according to the value of the inserted number counter. The winning combination is determined based on the table (S96). On the other hand, when the determination in S95 is “No”, the main CPU 64 selects any one of the general gaming state probability lottery tables shown in FIGS. 9A to 9C according to the value of the inserted number counter. A table is selected, and a winning combination is determined based on the selected table (S97).

  After performing the processing of S92, S94, S96 or S97, the main CPU 64 subsequently determines whether or not the determined winning combination is BB or RB (S98). When this determination is “Yes”, the main CPU 64 sets a carryover combination in the control RAM 66 based on the winning combination (S99). When the determination of S98 is “No” or when the processing of S99 ends, the main CPU 64 subsequently determines the winning combination determined in the current unit game and the carryover combination carried over to the current unit game. The logical sum is determined as the winning combination (S100), and the combined winning combination is stored in the control RAM 66. In other words, if BB or RB is determined as a winning combination in the previous unit game and a bonus is carried over as a carryover, and a small role other than the bonus is determined as a winning combination in this unit game, Winning flags for both small roles are raised

  Next, with reference to FIG. 19, the bonus operation check process performed in FIGS. 14 and S27 will be described.

  In this bonus operation check process, first, the main CPU 64 determines whether or not the display combination actually displayed on the activated pay line is BB or RB (see S111 in FIG. 19). If this determination is “No”, the bonus operation check process ends. On the other hand, if the determination in S111 is “Yes”, the main CPU 64 performs a BB operation process if the display combination is BB, and performs an RB operation process if the display combination is RB (S112). In the BB operation process, the BB operation flag is set to “ON” based on the BB operation table (see FIG. 13A), and “345” is the number of payable sheets at the BB operation in the BB payout number counter. Set. In the RB operation process, the RB operation flag is set to “on” based on the RB operation table (see FIG. 13B). Then, “12”, which is the number of games that can be played, is set in the RB game number counter, and “8”, which is the number of games that can be won, is set in the RB winning number counter. When the process of S112 ends, the main CPU 64 clears the carryover combination corresponding to the display combination established in the current unit game (S113), and ends the bonus operation check process.

  Next, with reference to FIG. 20, the bonus end check process performed in FIG. 14 and S28 will be described.

  In this bonus end check process, first, the main CPU 64 refers to the control RAM 66 to determine whether or not the RB operating flag is “ON” (see S121 in FIG. 20). When this determination is “Yes”, “1” is subtracted from the value of the RB game number counter, that is, the possible number of games. At this time, if a winning combination with a payout is established, the value of the RB winning number counter, that is, the number of possible winnings is also subtracted by “1” (S122). Next, the main CPU 64 determines whether or not at least one of the number of possible games and the number of possible winnings is “0” and the RB gaming state is over (S123). If this determination is “Yes”, an RB end process is performed to set the RB operating flag to “off” (S124). If the determination in S123 is “No”, or after performing the processing in S124, the main CPU 64 refers to the control RAM 66 to determine whether the BB operating flag is “on”. (S125). If this determination is “No”, the bonus end check process is terminated as it is.

  If the determination in S125 is “Yes”, or if the determination in S121 is “No”, the main CPU 64 determines the value of the BB payout number counter, that is, the payable number according to the number of medals to be paid out in the current game. Is subtracted (S126). Subsequently, the main CPU 64 determines whether or not the payable number is “1” or more and the BB continues (S127). When the payout possible number is “0” and the determination in S127 is “No”, the main CPU 64 performs a BB end time process for setting the BB operating flag to “off” (S128), and ends the bonus end check process. . At this time, when the RB operation flag is “ON”, the RB end time process is also performed.

  On the other hand, if the determination in S127 is “Yes”, the main CPU 64 determines whether or not the display combination in the current unit game is SRB (S129), and if this determination is “No”, The bonus end check process is terminated as it is. On the other hand, when the determination in S129 is “Yes”, the RB operation time process is performed based on the RB operation time table (see FIG. 13B) (S130). Subsequently, the main CPU 64 clears the carryover combination (S131) and ends the bonus end check process.

  According to the pachislot machine 1 according to the present embodiment, as described above, the game state is entered at the start of each unit game while the game state is shifted to the general game state during BB and the specific game is being performed. The maximum inserted number of medals is determined by the maximum inserted number determination process (see S44 in FIG. 15) using the maximum inserted number lottery table (see FIG. 8). For this reason, while a general game is being played during BB, the maximum number of medals inserted varies for each unit game in accordance with the lottery result in the maximum inserted number determination process. Accordingly, the winning probability of each winning combination in the general game in BB is a probability lottery table (FIG. 11) according to the number of medals inserted (usually determined maximum inserted number) within the range of the determined maximum inserted number. (See (a) to (c)), it is changed for each unit game. As a result, the number of medals that can be obtained by a player in the general game during BB depends on the lottery result in the maximum insertion number determination process. Is no longer monotonous and the fun of general games in BB increases.

  In the above embodiment, a case has been described in which a general game in the BB is a specific game, and the maximum inserted number is determined by lottery when the specific game is being performed, but the present invention is limited to this. It is not a thing. The RB game in the RB game state may be a specific game, and the maximum inserted number may be determined by lottery when the specific game is being performed. In addition, a specific game section such as a period from when a bonus such as BB or RB ends until a predetermined number of games elapses, or a general game is set as a specific game, and the maximum inserted number is determined by lottery. Is also possible.

  In the above embodiment, the case where the lottery of the maximum number of inserted medals is performed for each unit game in the general game state during BB has been described, but the present invention is not limited to this. For example, when the BB operating flag is set to “ON”, a lottery of the maximum inserted number is performed once. Thereafter, until the BB operating flag is set to “OFF”, the game with the first determined maximum inserted number is played. It may be a configuration in which is performed.

  In the above embodiment, the case where the gaming machine according to the present invention is applied to the pachislot machine has been described, but the winning probability of each winning combination in the lottery by the winning combination determining means is changed according to the amount of game value to be inserted. The present invention can also be applied to other gaming machines. Even when the present invention is applied to such a gaming machine, the same effects as the above-described embodiment can be obtained.
