"Re-game combination" and a general combination for paying out a predetermined number of game media when winning.

  Here, “winning game” means “winning game” in which when a winning game is won by lottery and a game corresponding to the winning game stops and wins, the game proceeds in a manner advantageous to the player. It is a role that can be performed. The winning combination includes a big bonus combination (hereinafter referred to as BB combination) and a regular bonus combination (hereinafter referred to as RB combination), and other arbitrary winning games can be set.

  The RB combination is a combination that shifts to an RB game that is one of the winning games. In this RB game, a game in which a predetermined combination is won with a high probability can be performed a predetermined number of times under a certain condition. In addition, the BB role is a role for shifting to a BB game that is one of the winning games. This BB game can be used for general games and can be transferred to RB games under certain conditions during the general games. This is a game in which a general game and an RB game can be repeated until a predetermined number of game media payouts is reached.

  In addition, the “combination” includes not only the above winning combination, but also a general combination that pays out a predetermined number of game media when winning, or “re-game” that allows a game to be re-executed without inserting a game media. For example, a “re-game” can be set.

  The “general combination” is a combination in which a predetermined number of game media are paid out when a general combination is won by lottery and a symbol corresponding to the general combination is won.

  “Re-playing” means that when a re-playing role is won by lottery and the symbol corresponding to the re-playing role stops and wins, the next game can be executed without throwing in game media. (Also called replay). Various other combinations can be added according to the game mode.

  In the “role lottery” for determining one combination, for example, it is desirable to generate a random number and determine one winning combination based on the value. Regarding the generation of random numbers, it is conceivable to use a random number generator or to generate them on software using a computer or the like.

  “Corresponding symbols stop” means, for example, that symbols determined corresponding to roles for each reel stop on a predetermined effective line, and predetermined symbols are aligned. In this case, a setting for stopping a predetermined symbol on all reels is included, and a setting for stopping a predetermined symbol on some reels is also included. Further, the predetermined symbol can be set to the same symbol for all the reels, or a different symbol can be set for each reel.

  The “effect” is an effect that is performed separately from the original game of the gaming machine.

<Description of main routine>
First, the control process of the main routine will be described with reference to the flowchart of FIG. In this main routine, a control process when a game is performed once, in which one step from when a player inserts a game medium until a plurality of reels displaying a plurality of symbols is rotated and stopped is performed once. Indicates.

  First, it is determined whether or not the value of the parameter NRP is greater than 0 (step S11). Here, the NRP is a parameter that determines whether or not to replay, and is set so that replay is performed when it is larger than 0, and replay is not performed when it is 0 or less. Further, as shown in step S146 of FIG. 12, when the re-game player is won and won, 1 is input as the value of NRP.

  If it is determined in step 11 that the value of NRP is 0 or less (NO), it is determined that no re-game is performed, and then it is determined whether or not a game medium has been inserted (step). S12). If it is determined in this determination that a game medium has been inserted (YES), the process proceeds to step S15, and the inserted number counted by the game medium counter installed below the game medium insertion port 38 is detected as the number of bets. To do. However, when the number of game media exceeding the specified number (three in this embodiment) is inserted, the game media exceeding the specified number is stored in the RAM 110 as the number of credits.

  If it is determined in step S12 that no game medium is inserted (NO), it is next determined whether or not there is a credited game medium (step S13). If it is determined in this determination that there is no credited game medium (NO), the process returns to step S12 again, and the determination processes in steps S12 and S13 are repeated.

  If it is determined in step S13 that there is a credited game medium (YES), it is next determined whether or not a bet operation signal has been received (step S14). This bet operation signal is transmitted when the player operates any one of the bet switches 32, 34, or 36. If it is determined in this determination that the bet operation signal has not been received (NO), the process returns to step S12 again, and the determination processing from step S12 to step S14 is repeatedly executed. If it is determined in step S14 that a bet signal has been received (YES), the number of bets is detected from the received bet operation signal (step S15). In either case of inserting a game medium or using a credited game medium, the detected bet number is stored in the RAM 110 as a new bet number, and when using a credited game medium, A process of subtracting the number of credits of the game medium by the number of detected bets is performed (step S16). Then, the process proceeds to a combination lottery processing subroutine (step S18).

  If it is determined in step S11 that the value of NRP is greater than 0 (YES) and the player is in the replaying state, 0 is input to the value of NRP to cancel the replaying state (step S17). Without performing the process from S12 to step S16, the process proceeds to the winning lottery process subroutine (step S18). That is, when it is determined that the game is in the re-gaming state, the game can be performed without newly inserting a game medium or consuming the credited game medium. In this embodiment, the bet number in the re-game is controlled so as to set the same bet number as the bet in the previous game. However, a bet number different from the bet number in the previous game is set. It is also possible to perform control.

  In the combination lottery processing subroutine of step S18, combination lottery is performed by the combination lottery means 410, and a flag-on process for turning on the RB flag, the BB flag, the replay flag, and the general combination flag is performed according to the winning combination. . Details of this subroutine will be described later with reference to the flowcharts of FIGS.

  Subsequent to the role lottery processing subroutine (step S18), based on the result of the role lottery, the reel fluctuation and stop subroutine (step S19) performs control processing relating to the movement of the reels that are stopped after the reels 40L, 40C, 40R are rotated. ) Is performed. This reel fluctuation / stop subroutine is performed by the reel control means 440, and details of this subroutine will be described later with reference to the flowchart of FIG.

  Next, after the reels are stopped by the reel fluctuation / stop subroutine, a winning symbol determination is performed, and based on the determination result, a winning determination and flag off processing subroutine (step S20) for performing flag-off processing is performed. The details of this subroutine will be described later with reference to the flowcharts of FIGS.

  Then, a payout process (step S21) for paying out a predetermined number of game media corresponding to the winning game based on the winning lottery and winning symbol determination is performed. In the payout process, it is possible to actually pay out the game media from the game media payout outlet 62, or to credit a predetermined number of game media instead of paying out.

  When this payout process is completed, a game end signal is transmitted to the sub-control circuit 200 (step S22). The sub-control circuit 200 performs the determination process (see FIG. 15) in step S230 of the special effect control subroutine based on the signal transmitted in step S22.

  One game is completed by the above control process. By repeating the control process shown in this main routine, the player can play a plurality of times.

<Role lottery processing subroutine>
Next, the combination lottery processing subroutine performed in step S18 of the main routine will be described in detail with reference to the flowcharts shown in FIGS.

  First, it is determined whether a start switch ON signal has been received (step S31). The start switch ON signal is a signal transmitted by the operation means 300 when the player operates the start switch 50. Based on this signal, the reel control means 440 performs control for starting the rotation of the reel. This is performed (see step S63 in FIG. 8).

  If it is determined that the start switch ON signal is not received (NO), the determination process in step S31 is repeated. In other words, the player waits for the game to start until the player operates the start switch 50.

  If it is determined in step S31 that a start switch ON signal has been received (YES), a game start signal is transmitted to the sub-control circuit 200 (step S32). In the sub control circuit 200, based on the signal transmitted in step S32, the determination process in step S201 of the back lamp lighting subroutine (see FIG. 14) and the determination process in step S223 of the special effect control subroutine (see FIG. 15) are performed. .

  Subsequently, it is determined whether or not the value of the parameter NRB is greater than 0 (step S33). The NRB is a parameter that determines whether or not to play an RB game. The NRB is set so as to play an RB game when it is larger than 0 and not to play an RB game when it is less than 0. Further, as shown in step S124 in FIG. 11 and step S165 in FIG. 13, when the RB combination is won and won, 1 is input as the NRB value.

  If it is determined in step S33 that the NRB value is greater than 0 (YES), the RB lottery table stored in the ROM 108 is read (step S34), and the process proceeds to step S39. Here, an example of the RB lottery table is shown in FIG.

  In this subroutine routine, the RB lottery table (see step S34, the BB operation lottery table (see step S36), and the BB non-operation lottery table (see step S38) stored in the ROM 108 is read according to the gaming state. (See step S39) Each lottery table used in this role lottery has a six-stage setting table of settings 1 to 6, and each combination has a setting stage. Specifically, as the setting number (1-6) increases in the BB inactive lottery table, the number of winning combinations such as RB combination and BB combination increases. In other words, when the BB is not operating, it is easy to win a winning combination in the winning lottery when setting 6 and it is most difficult to win a winning combination in the winning lottery when setting 1 Yes. During RB operation, and at the time of BB operation, the same numeric is defined in the setting 1-6.

  In the RB lottery table, a winning combination of symbol number 1 and a symbol number 2 are set to be different, and in the case of winning combination, it is set to win when all three reels have JAC symbols. . The number of winning combinations in the lottery performed in step S39 described later is 65036, and a very high probability that the winning probability is about 1 / 1.01 (65036/65536) is set. Therefore, in RB games, the possibility of winning a winning combination is high, and conversely, the number of outliers is 500, and the probability is set to about 1/131 (500/65536). Is unlikely. As described above, in the RB lottery table, the same numbers are set in the settings 1 to 6.

  If it is determined in step S33 that the NRB value is 0 or less (NO), it is next determined whether or not the parameter NBB value is greater than 0 (step S35). NBB is a parameter that determines whether or not to play a BB game, and is set so that a BB game is played when it is larger than 0 and a BB game is not played when it is 0 or less. Further, as shown in step S162 of FIG. 13, when the BB combination is won and won, 1 is input as the value of NBB.

  If it is determined in step S35 that NBB is larger than 0 (YES), the BB operation general lottery table stored in the ROM 108 is read (step S36). Here, an example of the general lottery table during BB operation is shown in FIG.

  The general lottery table during BB operation is a lottery table used when the BB game is in progress and not in the RB game. If the BB game is being played and the RB game is being played, the RB lottery table shown in FIG. 18 is used. In the general lottery table at the time of BB operation, three types of general combinations of symbol numbers 1 to 3, an RB combination of symbol number 4 and a deviation of symbol number 5 are set. Here, in comparison with a general lottery table when BB is not operated (see FIG. 20), which will be described later, the general lottery table when BB is operated is set so that there is no re-game combination and BB combination.

  In the general roles 1 to 3 with the symbol numbers 1 to 3, first, the general role 1 with the symbol number 1 has a placement number of 1000 and a winning probability of about 1/66 (1000/65536). If the reel symbol is cherry, the remaining two reel symbols are set to win any symbol. General number 2 with symbol number 2 is set to win when the number in the lottery is 6500, the winning probability is about 1/10 (6500/65536), and all three reels have the same bell symbol. Has been. The general combination 3 with symbol number 3 is set to win when the number in the lottery drawing is 500 and the winning probability is about 1/131 (500/65536) and all three reels have the same watermelon symbol. Has been.

  The RB role of symbol number 4 has 21845 in the lottery, the winning probability is about 1/3 (21845/65536), the left and middle reels have replay symbols, and the right reel has a bell symbol. It is set to win a prize when they are complete. In the BB operation lottery table, the probability of winning the RB combination is set to be very high as compared to the BB non-operation general lottery table (see FIG. 20) described later. Further, the number of symbols out of symbol number 5 in the role lottery is 35691, and the probability is set to about 1 / 1.84 (35691/65536). As described above, in the BB operation lottery table, the same numbers are set in the settings 1 to 6.

  Subsequent to step S36, a BB gaming signal is transmitted to the sub-control circuit 200 (step S37), and the process proceeds to step S39. The sub-control circuit 200 performs the determination process (see FIG. 14) in step S201 of the back lamp lighting subroutine based on the signal transmitted in step S37.

  Next, if it is determined in step S35 that the NBB value is 0 or less (NO), the BB non-operating general lottery table stored in the ROM 108 is read (step S38). Here, an example of the general lottery table when the BB is not operated is shown in FIG.

  The BB non-operating general lottery table is a lottery table used in the normal gaming state, as described above. The three types of general combinations of symbol numbers 1 to 3, the re-game combination of symbol number 4, and the symbol number 5 RB combination, symbol number 6 BB combination, and symbol number 7 are set off.

  The three types of general combinations of symbol numbers 1 to 3 have the same settings for the above-described general lottery table during BB operation (see FIG. 19) and the setting of the number, winning probability and symbol in the combination lottery. In addition, the re-playing role of symbol number 4 has a number in the winning lottery process of 8978, and the winning probability is about 1 / 7.3 (8978/65536), and the three reels have replay symbols. It is set to win. In addition, about the general combination 1-3 of the symbol numbers 1-3, and the re-game player of the symbol number 4, the same number is defined in the settings 1-6.

  For the RB combination of symbol number 5, the following values are set for the number and winning probability in the combination lottery process in settings 1-6. In setting 1, the number of places is 28 and the winning probability is set to about 1/2341 (28/65536). In setting 2, the number of places is set to 30, and the winning probability is set to about 1/2184 (30/65536). In setting 3, the number of places is 31 and the winning probability is set to about 1/2114 (31/65536). In setting 4, the number of places is 33 and the winning probability is about 1/1986 (33/65536). In setting 5, the number is 36 and the winning probability is about 1/1820 (36/65536). In setting 6, the number is 39 and the winning probability is about 1/1680 (39 / 65536). In addition, when the RB winning combination is won in the winning lottery, the winning is set when the symbols of BAR are aligned on all three reels.

  In the BB combination with the symbol number 6, in the settings 1 to 6, the following values are set for the number and winning probability in the combination lottery process. In setting 1, the number is 176 and the winning probability is set to about 1/372 (176/65536). In setting 2, the number is set to 180 and the winning probability is set to about 1/364 (180/65536). In setting 3, the number is 185 and the winning probability is set to about 1/354 (185/65536). In setting 4, the number is 190 and the winning probability is about 1/345 (190/65536). In setting 5, the set number is 198 and the winning probability is set to about 1/331 (198/65536). In setting 6, the set number is 206 and the winning probability is set to about 1/313 (206 / 65536). In addition, when the BB combination is won in the combination lottery, the winning is set when the three reels have the red 7 symbols.

  As described above, for the RB combination and the BB combination, as the setting value (1 to 6) increases, the winning probability in the combination lottery increases, and in the setting 6, the winning probability is the highest. That is, the greater the set value (1-6), the higher the possibility that the game will proceed advantageously for the player. In addition, different numbers and probabilities of losing in the role lottery are determined according to the values of the RB combination and the BB combination in the settings 1 to 6.

  As described above, after the lottery table corresponding to the state of the game is read out, the lottery for acquiring the random number and performing the lottery determination is performed (step S39). Specifically, random numbers generated by the random number generator 112 are extracted by the random number extraction means 420, and the random number determination means 430 compares the extracted random numbers with the read lottery table and determines the winning.

  Subsequently to FIG. 6, the process proceeds to FIG. 7, and it is determined whether or not the RB combination is won as a result of this determination (step S <b> 40). If it is determined that the RB combination is won (YES), the RB combination flag is turned on and stored in the RAM 110 (step S41), and the process proceeds to step S48.

  If it is determined in step S40 that the RB combination has not been won (NO), it is next determined whether or not the BB combination has been won (step S42). If it is determined in this determination that the BB combination is won by the combination lottery (YES), the BB combination flag is turned on and stored in the RAM 110 (step S43), and the process proceeds to step S48.

  If it is determined in step S42 that the BB combination is not won (NO), it is next determined whether or not the re-game combination is won (step S44). If it is determined in this determination that the re-game combination is won by the combination lottery (YES), the re-game flag is turned on and stored in the RAM 110 (step S45), and the process proceeds to step S48.

  If it is determined in step S44 that the re-playing combination is not won (NO), it is next determined whether or not the general combination is won (step S46). In this determination, if it is determined that the general combination is won by the combination lottery (YES), the general combination flag is turned on and stored in the RAM 110 (step S47), and the process proceeds to step S48.

  If it is determined in step S46 that the winning combination has not been won (NO), the flag on process is not performed and the process proceeds to step S48.

  After performing a series of processing relating to flag-on as described above, in step 48, the symbol number and control symbol data corresponding to the winning combination in the winning lottery are read from the ROM 108 and used for the reel fluctuation and stop subroutine described later. This data is stored in the RAM 110. The combination lottery processing subroutine is thus completed.

<Explanation of reel fluctuation / stop subroutine>
Next, in the main routine of FIG. 5, when the above-described combination lottery processing subroutine (step S18) is completed, a reel fluctuation and stop subroutine (step S19) is then performed. The reel fluctuation / stop subroutine will be described in detail with reference to the flowchart shown in FIG.

  First, the symbol number and control symbol data stored in step S48 of FIG. 7 are read (step S61). Then, it is determined whether or not a predetermined shortest time has elapsed (step S62). If it is determined in this determination that the shortest time has not elapsed (NO), the determination process in step S62 is repeatedly executed. That is, the rotation of the reel, which is the next process, cannot be started until the shortest time has elapsed. By this control, the number of games played in a certain time is controlled to be within a predetermined number.

  If it is determined in step S62 that the shortest time has elapsed (YES), the start switch ON signal has already been received (see step S31 in FIG. 6), and therefore the reel rotation start signal is transmitted to the motor drive circuit. 114, the rotation of the motors 80L, 80C, 80R is started, and the reels 40L, 40C, 40R are rotated (step S63).

  Next, it is determined whether or not the reel that has started rotating is rotating at a constant speed (step S64). If it is determined in this determination that the reel has not yet rotated at a constant speed (NO), the determination process in step S64 is repeated. That is, the reel stop control, which is the next step, cannot be performed until the rotation of the reel reaches a constant speed.

  If it is determined in step S64 that the reel has been rotated at a constant speed (YES), it is next determined whether a reel stop signal has been received (step S65). Here, the reel stop signal is a signal transmitted by the operation means 300 when the player pushes any one of the stop switches 52L, 52C, 52R.

  If it is determined in step S65 that the reel stop operation detection signal has been received (YES), the reel control means 440 controls the reel symbol combination control (stop control) corresponding to the stop switch that has transmitted the operation detection signal. ) (Step S66), the process proceeds to step S67.

  Here, the control processing in steps S65 and S66 will be described in more detail. When the stop switch 52L for the left reel is pushed, the reel control means 440 uses the motor 80L that rotates the left reel 40L. Stop control of step S66 is performed. Similarly, when the stop switch 52C for the middle reel is pushed, the stop control in step S66 is performed for the motor 80C that rotates the middle reel 40C, and the stop switch 52R for the right reel is pushed. In this case, the stop control in step S66 is performed for the motor 80R that rotates the right reel 40R.

  In the symbol combination control (stop control), based on the symbol number and control symbol data read out in step S61, the reel is slid by a maximum of four frames so that a predetermined symbol is stopped or not stopped within the range. Motor stop control is performed. Further detailed description of the control is omitted.

  If it is determined in step S65 that the reel stop signal has not been received (NO), the control proceeds to step S67 without performing control related to the stop. In step S67, it is determined whether all reels have stopped.

  If it is determined in this determination that all the reels are not stopped (NO), it is next determined whether or not the time limit has elapsed (step S68). If it is determined in this determination that the time limit has not been reached (NO), the process returns to step S65 again, and the control processing from step S65 to step S68 is repeated. As described above, until all the reels stop or until the time limit elapses, the process of performing symbol combination control (stop control) of the corresponding reels is repeated every time the reel stop signal is received.

  If it is determined in step S68 that the time limit has passed (YES), automatic symbol stop control is performed on the reels that are still rotating to stop all reels (step S69), and the process proceeds to step S70. move on. In this automatic symbol stop control, the maximum four symbol (four frames) stop positions can be shifted, and stop control is performed so that the winning symbols are not always aligned within the range.

  Next, returning to the determination in step S67, if it is determined that all the reels are stopped (YES), the process proceeds to step S70. In step S70, a full stop signal is transmitted to the sub-control circuit 200, and this subroutine is terminated. The sub-control circuit 200 performs the determination process in step S202 of the back lamp lighting subroutine based on the signal transmitted in step S70 (see FIG. 14).

<Explanation of Winning Determination and Flag Off Processing Subroutine>
In the main routine of FIG. 5, when the reel fluctuation / stop subroutine (step S19) is completed, a winning determination and flag-off process subroutine (step 20) is performed. Next, the winning determination and flag off processing subroutine will be described in detail with reference to the flowchart shown in FIG.

  First, it is determined whether or not the game state is RB game (step S91). If it is determined in this determination that the RB game is being played (YES), an RB game processing subroutine (step S92) is performed, and the winning determination and flag-off process subroutine is terminated. A detailed description of the RB game processing subroutine will be described later.

  If it is determined in step S91 that the game state is not RB game (NO), it is next determined whether or not the game state is BB game (step S93). If it is determined in this determination that the BB game is being played (YES), a BB gaming process subroutine (step S94) is performed, and the winning determination and flag-off process subroutine is terminated. A detailed description of the BB game processing subroutine will be described later.

  If it is determined in step S93 that the game state is not BB game (NO), it is next determined whether or not there is a winning combination (step S95). If it is determined in this determination that there is a winning combination (YES), a winning combination processing subroutine (step S96) is performed, and the winning determination and flag off processing subroutine is terminated. A detailed description of the winning combination processing subroutine will be described later.

  If it is determined in step S95 that there is no winning combination (NO), the winning determination and flag-off processing subroutine is terminated. Details of the general processing subroutine will be described later.

  Hereinafter, a detailed description of the subroutine shown in steps S92, S94, and S96 will be given.

<Description of processing subroutine during RB game>
First, a detailed description of the RB game processing subroutine (step S92) executed when it is determined in step 91 that the RB game is being performed will be described with reference to the flowchart shown in FIG.

  First, it is determined whether or not the reel symbol stopped by the reel fluctuation / stop subroutine described above has won a prize (step S101). Next, the game count and the winning count are counted, the game count and winning count data are updated, and the updated data is stored in the RAM 110 (step S102). These data are used as the RB game end condition. When the number of games or the number of winnings reaches a predetermined number, the RB game is ended.

  Next, it is determined whether or not a BB game is being played (step S103). If it is determined in this determination that the BB game is being played (YES), that is, the BB game is being played in the RB game, the payout number is counted to update the payout number data, and the updated data is stored in the RAM 110. (Step S104). This data is used as a BB game end condition. When the payout number reaches a predetermined number, the BB game is ended.

  Next, it is determined whether or not the BB game end condition has been achieved (step S105). If it is determined in this determination that the BB game end condition has been achieved (YES), 0 is input to the values of NBB and NRB to cancel the RB game state and the BB game state (step S106). . Next, a BB end signal is transmitted to the sub control circuit 200 (step S107), and this subroutine is ended. The sub-control circuit 200 performs the determination process of step S231 of the special effect control subroutine based on the signal transmitted in step S107 (see FIG. 15).

  If it is determined in step S105 that the BB end condition is not achieved (NO), it is next determined whether or not the RB end condition is achieved (step S108). In this determination, if it is determined that the RB end condition is achieved (YES), 0 is input to the value of NRB to release the RB gaming state (step S109), and this subroutine is ended. If it is determined in step S108 that the RB termination condition has not been achieved (NO), the subroutine is terminated without releasing the RB gaming state.

  Returning to the determination in step S103, if it is determined that the BB game is not being played (NO), it is next determined whether or not the RB end condition is achieved (step S110). In this determination, if it is determined that the RB end condition is achieved (YES), 0 is input to the value of NRB to release the RB gaming state (step S111), and this subroutine is ended. If it is determined in step S113 that the RB termination condition has not been achieved (NO), the subroutine is terminated without releasing the RB gaming state.

<Description of processing subroutine during BB game>
Next, FIG. 11 shows a detailed explanation of the BB game processing subroutine (see step S94) executed when it is determined in step S93 that the BB game is being played in the winning determination and flag off processing subroutine (see FIG. 9). This will be described with reference to the flowchart shown.

  First, it is determined whether or not a reel symbol stopped by the reel fluctuation and stop subroutine described above has won a prize (step S121). Next, as a result of the winning symbol determination, it is determined whether or not any winning combination has been won (step S122). If it is determined in this determination that there is a winning (YES), it is then determined whether or not the RB combination has won (step S123). If it is determined in this determination that the RB combination has won (YES), 1 is input to the NRB value to set the RB gaming state (step S124), and the RB flag is turned off (step S125). The process proceeds to step S128.

  If it is determined in step S123 that the RB combination has not won (NO), the general combination flag is turned off (step S126), and the process proceeds to step S128. Returning to the determination in step S122, if it is determined that there is no winning (NO), if any flag is turned on, the flag is turned off (step S127), and the process proceeds to step S128.

  In step S128, the payout number is counted, the payout number data is updated, and the updated data is stored in the RAM 110. This data is used as a BB game end condition, and when the payout number reaches a predetermined number, the BB game is ended.

  Next, it is determined whether or not the BB game end condition has been achieved (step S129). If it is determined in this determination that the BB game end condition has been achieved (YES), 0 is input to the value of NBB to release the BB game state (step S130). Then, a BB end signal is transmitted to the sub control circuit 200 (step S131), and this subroutine is ended. The sub-control circuit 200 performs the determination process of step S231 of the special effect control subroutine based on the signal transmitted in step S131 (see FIG. 15).

  If it is determined in step S129 that the BB termination condition has not been achieved (NO), this subroutine is terminated as it is.

<Explanation of the processing sub-routine at the time of winning>
Next, in the winning determination and flag off processing subroutine (see FIG. 9), the detailed explanation of the winning combination processing subroutine (see step S96) executed when it is determined in step S95 that there is a winning combination is shown in the flowchart of FIG. Will be described.

  First, it is determined whether or not a reel symbol stopped by the reel fluctuation and stop subroutine described above has won a prize (step S141). Next, as a result of the winning symbol determination, it is determined whether or not any winning combination has been won (step S142).

  If it is determined in this determination that a prize has been won (YES), it is next determined whether or not the BB combination or the RB combination has won (step S143). If it is determined in this determination that the BB combination or RB combination has won (YES), the BB / RB determination processing subroutine is performed (step S144), and this subroutine is terminated. A detailed description of the BB and RB determination processing subroutine will be described later.

  If it is determined in step S143 that the BB combination or the RB combination has not won (NO), it is next determined whether or not the re-game combination has won (step S145). If it is determined in this determination that the re-game player has won (YES), 1 is input to the value of NRP to set the re-game state (step S146). Then, the re-gamer flag is turned off. If the BB and RB flags are turned on, carry-over processing of the BB and RB flags is performed (step S147), and the re-gamer winning signal is sent to the sub-control circuit. 200 (step S148), and this subroutine is terminated. The sub control circuit 200 performs the determination process in step S203 of the back lamp lighting subroutine based on the signal transmitted in step S148 (see FIG. 14).

  If it is determined in step S145 that the re-playing role is not won (NO), it is determined that the general role has been won, the general role flag is turned off, and the BB and RB flags are turned on. If YES, the BB and RB flag carry-over processing is performed (step S149), and a general winning prize signal is transmitted to the sub-control circuit 200 (step S150), and this subroutine is terminated. The sub control circuit 200 performs the determination process in step S203 of the back lamp lighting subroutine based on the signal transmitted in step S150 (see FIG. 14).

  Returning to the determination in step S142, if it is determined that there is no winning (NO), it is next determined whether or not the BB and RB flags are on (step S151). In this determination, if it is determined that the BB and RB flags are turned on (YES), carry-over processing of the BB and RB flags is performed, and the other flags (re-playing game, general game) are turned on. If so, the flag is turned off (step S152), and this subroutine is terminated.

  If it is determined in step S151 that the BB and RB flags are not turned on (NO), the flag-on flag (re-gamer, general player) is turned off (step S153), Exit the subroutine.

<BB, RB determination processing subroutine>
Next, in the winning combination processing subroutine (see FIG. 12), a detailed explanation of the BB / RB determination processing subroutine (see step S144) executed when it is determined in step S143 that the BB winning combination or RB winning combination has been won. This will be described with reference to the flowchart shown in FIG.

  First, it is determined whether or not the BB combination has won a prize (step S161). If it is determined in this determination that the BB combination has won (YES), 1 is input as the NBB value to set the BB gaming state (step S162), and the BB flag is turned off (step S163). . Then, a BB winning signal is transmitted to the sub control circuit 200 (step S164), and this subroutine is finished. The sub control circuit 200 performs the determination process in step S221 of the special effect control subroutine based on the signal transmitted in step S164 (see FIG. 15).

  Returning to the determination of step 161, if it is determined that the BB combination has not won (NO), it is determined that the RB combination has won, and 1 is input to the value of the NRB to set the RB gaming state. This is performed (step S165). Then, the RB flag is turned off (step S166), and this subroutine is terminated.

<Description of main routine (continued)>
As described above, the subroutine shown in steps S92, S94, and S96 ends, and the winning determination and flag off processing subroutine shown in FIG. 9 ends. Here, returning to the main routine of FIG. 5, the winning determination and flag-off process subroutine in step S20 is terminated, the payout process in step S21 is terminated, and a game end signal is transmitted to the sub-control circuit 200 (step S22). This main routine ends. Thereby, the control process for performing a game in which one process from the time the symbol fluctuates until it stops is completed.

<Back lamp lighting subroutine>
Next, the back lamp lighting subroutine performed in the sub-control circuit 200 will be described using the flowchart shown in FIG. In this subroutine, in the game when the BB is not in operation, an effect of lighting the back lamp of the display graphic arranged on the right side of the reel on the front panel is performed based on the winning of the general combination or the re-playing combination.

  First, after receiving a game start signal (see step S32 in FIG. 6) from the main control circuit 100, it is determined whether a BB gaming signal (see step S37 in FIG. 6) has been received (step S201). If it is determined in this determination that the BB game in-progress signal has been received after receiving the game start signal (YES), that is, it is determined that the game is in BB operation, this subroutine is terminated.

  If it is determined in step S201 that the BB gaming signal is not received after receiving the game start signal (NO), the main control circuit 100 next sends a full stop signal (see step S70 in FIG. 8). ) Is received (step S202). If it is determined in this determination that the full stop signal has not been received (NO), the determination process in step S202 is repeated as it is. That is, it is in a standby state until a full stop signal is received.

  If it is determined in step S202 that all stop signals have been received (YES), then the main combination winning signal (see step S150 in FIG. 12) or the replay winning signal (see FIG. 12) from the main control circuit 100. (See step S148) is received (step S203). If it is determined in this determination that neither a general winning prize signal nor a replay winning signal has been received (NO), that is, neither a general winning prize nor a replay winning prize has been won, the present subroutine is terminated as it is. Here, the general combination winning signal also includes information on which of the general combinations 1 to 3 has been won. Even during the BB operation, during the RB game, since the BB game in-progress signal is not received in the determination in the above step S201, the process proceeds to the control processing after the step S202, but the determination in the step S203 always ( NO) is determined, and this subroutine is finished.

  If it is determined in step S203 that the general combination or re-playing combination has won (YES), it is next determined whether or not the general combination 1 (cherry) has won (step S204). In this determination, if it is determined that the general combination 1 has won (YES), the process proceeds to step S210. If it is determined in step S204 that the general combination 1 has not won (NO), it is next determined whether or not the general combination 3 (watermelon) has won (step S205). If it is determined in this determination that the general combination 3 has won (YES), the process proceeds to step S210.

  If it is determined in step S204 that the general combination 3 has not won (NO), it is next determined whether or not the general combination 2 (bell) has won (step S206). If it is determined that the general combination 2 has not won (NO), the process proceeds to step S208. If it is determined in step S206 that the general combination 2 has won (YES), it is determined whether the general combination 2 has won two or more times in succession, that is, the general combination following the previous game. It is determined whether or not 2 has won (step S207). In this determination, if it is determined that the general combination 2 has won two or more times (YES), the process proceeds to step S210. Even when the general combination 2 wins three times or more, it is determined as (YES) in the determination of step S207.

  If it is determined in step S207 that the general combination 2 has not won the winning combination twice or more (NO), it is next determined whether or not the re-playing combination (replay) has won (step S207). S208). If it is determined that the re-game player has not won (NO), this subroutine is terminated as it is. Also, if it is determined in step S208 that the re-gamer has won (YES), next, whether or not the re-gamer has won more than three times, that is, following the previous two games. It is then determined whether or not the re-game player has won a prize (step S209). If it is determined in this determination that the re-game player has won three or more times (YES), the process proceeds to step S210. It should be noted that when the re-winning combination is won four or more times, it is determined as (YES) in the determination of step S209. If it is determined in step S209 that the re-game player has not won a prize three times or more (NO), this subroutine is terminated.

  When receiving a winning signal for the general combination 2 or replaying combination, the effect control means counts the number of winnings of each combination and stores it in the RAM 210. Then, when the continuous winning is interrupted, a control process is performed to reset the counted number of winnings to zero. Based on the counted number of winnings, the determination process of step S207 or step S209 is performed.

  In step S210, a control process for adding 1 to the value of the number N of the display figure whose backlight is turned on is performed (step S210). In the initial state at the start of the game, 0 is input to the value of N, and as will be described later, when the special effect is performed and the BB game ends, the back lamp is turned off, and N The value 0 is input to be initialized again (see step S234 in FIG. 16).

  Following step S210, it is determined whether the value of N is greater than 5 (step S211). If it is determined that the value of N is greater than 5 (YES), this subroutine is terminated. If it is determined in step S211 that the value of N is 5 or less (NO), the back lamp of the Nth display graphic is turned on (step S212), and this subroutine is terminated.

  In other words, in the game when the BB is not activated, when the general combination 1 or the general combination 3 wins, when the general combination 2 wins twice or more continuously, or when the re-playing combination wins three or more times, Each time the above requirement is achieved, the backlight is turned on one by one from the display figure of N = 1. Then, in a state where all the backlights of the display figures of N = 1 to 5 are turned on, the present subroutine is finished without turning on any more lights according to the determination in step S211.

  Here, FIG. 23 shows an embodiment of the display graphic of the present invention. The display figure of this embodiment is arranged on the right side of the right reel 40R on the front panel 20, and from the bottom N = 1 spear, N = 2 shield, N = 3 sword, N = 4 gun, A cannon figure of N = 5 is displayed. Then, every time the above requirement is achieved, the backlight is turned on in order from the lower N = 1 figure to the upper N = 5 figure. Through the effects using the graphic display as described above, the player can feel the game fun more strongly when the BB is not activated, and can be expected to increase the interest in the game.

<Special production control subroutine>
Next, the special effect control subroutine performed in the sub-control circuit 200 will be described using the flowcharts shown in FIGS. In this subroutine, control for performing a special effect or a normal effect in the game at the time of BB operation is shown, and control processing in a plurality of games from when the BB combination wins until the BB game is ended is shown.

  First, it is determined whether or not a BB winning prize signal (see step S164 in FIG. 13) is received from the main control circuit 100 (step S221). If it is determined in this determination that the BB winning prize signal has not been received (NO), this subroutine is terminated as it is. If it is determined in step S221 that the BB winning prize signal has been received (YES), the process proceeds to a special effect determination subroutine (step S222).

<Special production decision subroutine>
Here, the control processing of the special effect determination subroutine will be described using the flowchart shown in FIG. In this subroutine, at the start of the BB game, it is determined whether or not a special game is to be performed. When performing a special effect, a special effect lottery for determining one special effect from a plurality of special effects is performed. Do.

  First, it is determined whether or not the value of the number N of the display figure whose backlight is lit is 5 or more, that is, whether or not the backlights of all display figures from N = 1 to 5 are lit. (Step S251). In this determination, if it is determined that the value of the number N of the display figure is 5 or more (YES), it is determined that the special effect is performed, and the special effect lottery table stored in the ROM 208 is read and the special effect lottery is read out. Is performed (step S252).

  Here, FIG. 21 shows an embodiment of the special effect lottery table of the present invention. In this embodiment, the contents of the contents that impress defeat to the players of the special effects number K = 1 to 4, and the effects 1 to 4 of the contents that impress the victory, and the players of the special effects number K = 5 to 8. There are a total of eight different effects, consisting of defeats 1 to 4, which are effects. In these effects, the numbers in the special effect lottery are determined, and different values are set corresponding to the settings 1 to 6 in the role lottery.

  The numbers of the productions of K = 1 to 4 that impress the player with the victory increase in the order of the settings 1 to 6, and conversely, the effects of the production of K = 5 to 8 that impress the player with the defeat The value of the numerical value decreases in the order of settings 1-6. That is, the larger the value of the setting number (1-6), the easier it is to select an effect of K = 1-4 that impresses the player with a lottery, and the larger the value of the setting number (1-6). , It becomes difficult to select an effect of K = 5 to 8 that impresses the player in the lottery.

  More specifically, for example, the probability that an effect of K = 1 to 4 that impresses a player with a special effect lottery is selected is about 1/10 (26/256) in setting 1, but is set 6 is about 1 / 4.56 (56/256). On the other hand, the probability that an effect of K = 5-8 that impresses the player in the special effect lottery is selected is about 1 / 6.7 (38/256) in setting 1, but about 1 in setting 6 / 32 (8/256).

  Therefore, in the game when the BB is not activated, when the probability that the winning combination such as the BB role or the RB role is won in the role lottery is set, the effect that impresses the player in the special effect lottery is selected. The probability is set high, and the player can enjoy the progress of the game by imagining the probability of winning the winning combination in the role lottery based on the contents of the special performance, and increase the interest in the game Can be expected.

  Specifically, the lottery processing of the special effect lottery is performed by extracting a random number generated by a random number generator (not shown) in the sub-control circuit 200 by a random number extracting means (not shown), and determining a random number judging means (see FIG. (Not shown) determines the effect selected by comparing the extracted random number and the above-described special effect lottery table read out.

  Then, the image data of the special effect number K determined by the special effect lottery is read from the image data of the special effect stored in the ROM 208 and stored in the RAM 210 (step S253). Here, FIG. 22 shows an example of the image data of the special effect numbers K1 to 8 stored in the ROM 208. Each effect (K = 1-8) is displayed over 8 games, and images J (J = 1-8) of scenes with different progress are displayed for each game.

  Returning to the description of the flowchart, next, 1 is input to the value of the parameter ENSHUTU (step S254). ENSHUTU is a parameter that determines whether or not to perform a special effect (see step S224 in FIG. 15), and 0 is input in an initial state at the start of the game. Next, 1 is input to the value of the scene number J for each special effect game (step S255), and this subroutine is terminated.

  In the determination in step S251, if it is determined that the display graphic number N is smaller than 5, that is, the backlights of all display graphics with N = 1 to 5 are not lit (NO), It is determined that no effect is to be performed, and the image data of the normal effect stored in the ROM 208 is read out and stored in the RAM 210 (step S256). Then, 0 is input as the value of the parameter ENSHUTU (step S257), and this subroutine is terminated. In the present embodiment, the image data of the effect performed during the BB game at the time of winning the BB role is read (see steps S253 and 256), but the image data can also be read for each game.

<Special production control subroutine (continued)>
Returning to the description of the special effect control subroutine, it is determined whether or not a game start signal (see step S32 in FIG. 6) is received from the main control circuit 100 following the special effect determination subroutine in step S222 (step S223). ). If it is determined that the game start signal has not been received (NO), the control process of step S223 is repeated as it is. That is, after winning the BB, it is in a standby state until the next game is started.

  If it is determined in step S223 that the game start signal has been received (YES), it is next determined whether or not the value of the parameter ENSHUTU is greater than 0 (step S224). If it is determined in this determination that the value of ENSHUTU is greater than 0 (YES), the scene number for each game in the image data of the special effect number K stored in the RAM 210 (see step 253 in FIG. 17). The image data corresponding to J is transmitted to the display driving device to display the image (step S225). Then, control processing for adding 1 to the value of J is performed (step S226), and it is determined whether or not the value of J is greater than JMAX (step S227). Here, JMAX is the maximum number of scenes for each special effect (K = 1 to 8). In this embodiment, the value of JMAX is 8 in all cases. Note that the value of JMAX can be different for each effect.

  If it is determined in step S227 that the value of J is greater than JMAX (YES), then the values of ENSHUTU and J are initialized by inputting 0 (step S228), and the process proceeds to step S230. With this process, the normal performance is performed from the next game. If it is determined in step S227 that the value of J is less than or equal to JMAX (NO), the process proceeds directly to step S230.

  Returning to the determination in step S224, if it is determined that the value of ENSHUTU is 0 or less (NO), the image data of the normal effect stored in the RAM 210 (see step 256 in FIG. 17) is transmitted to the display driving device. The image is displayed (step S229), and the process proceeds to step S230.

  In step S230, it is determined whether or not a game end signal (see step S22 in FIG. 5) is received from the main control circuit 100. If it is determined by this determination that the game end signal has not been received (NO), the control process of step S230 is repeated. That is, the image display of the same special effect or normal effect is continued until the game ends. If it is determined in step S230 that a game end signal has been received (YES), then a BB end signal (see step S107 in FIG. 10 and step S131 in FIG. 11) is received from the main control circuit 100. Whether or not (step S231).

  In this determination, if the BB end signal has not been received (NO), that is, if the game at the time of BB operation still continues, the process returns to the determination process in step S223. Then, when the next game is started, the control processing from step S224 to S231 is performed, and the special effect or normal effect of the next scene J is displayed as an image.

  If it is determined in step S231 that the BB end signal has been received (YES), the process proceeds from FIG. 15 to FIG. 16, and then the value of the number N of the display graphic whose back lamp is lit is 5 It is determined whether or not this is the case (step S232). In this determination, if the value of N is 5 or more (YES), that is, if the back lamps of all display figures of N = 1 to 5 are turned on (special effects were performed), then All the back lamps that are lit are extinguished (step S233). Then, 0 is input to the value of N for initialization (step S234), and this subroutine is terminated.

  Further, in the determination at step S232, if the value of N is less than 5 (NO), that is, the back lamps of all display figures of N = 1 to 5 are not lit (no special effect was performed). ), This subroutine is terminated as it is. In this case, the back lamp of the display figure that is lit continues to be lit as it is. Therefore, in subsequent games when the BB is not activated, the player can easily turn on the back lamps of all display figures of K = 1 to 5 and enjoy special effects in the game when the BB is activated. it can.

(Other embodiments)
In the above-described embodiment, when the winning probability of winning combination in the combination lottery is set to be high, the probability of selecting an effect implying the player's victory in the special effect lottery is set to be high. The setting is not limited to this, and any setting can be made for the selection probability of the effect in the special effect lottery as long as it corresponds to the setting of the winning probability in the role lottery.

  In the above-described embodiment, when a predetermined requirement is achieved, the display graphic back lamp is turned on for notification. However, the present invention is not limited to this notification method, and image display is started on the display device. Any other notification method can be adopted.
