Description

The present invention relates to a gaming machine such as a pachislot gaming device.

Conventionally, in a gaming machine such as a pachislot gaming device, a hall manager or the like can freely change a set value that determines a probability of winning a winning combination such as a big bonus (BB) or a regular bonus (RB). it can. In the gaming machine described above, it is generally possible to change the set value by operating a switch or the like provided in the gaming machine after the store is closed. As a conventional gaming machine, for example, there is a gaming machine capable of visually distinguishing between a state in which a setting value can be changed and a state in which a setting value cannot be changed (see, for example, Patent Document 1).

On the other hand, among conventional gaming machines, there is a gaming machine in which the set value is automatically changed when a predetermined condition is satisfied. For example, there is a gaming machine that automatically changes a setting value to a setting value that is most unfavorable to the player when the RAM is initialized by unauthorized noise (see, for example, Patent Document 2). In addition, there is a gaming machine in which the probability for shifting to RB during execution of BB is changed when a predetermined condition is satisfied (see, for example, Patent Document 3). In addition, there is a gaming machine that automatically changes the set value in accordance with the position of the rotating reel when the stop button is operated (see, for example, Patent Document 4).
Furthermore, when the setting value is changed during business hours, there is a data aggregation system that can aggregate data before the setting value is changed and data after the setting value is changed. (For example, refer to Patent Document 5).

FIG. 3 is a block diagram showing an internal configuration of the pachislot gaming apparatus shown in FIG.
The main control circuit 81 has a microcomputer 40 disposed on a circuit board as a main component. The microcomputer 40 includes a CPU 41 that performs a control operation according to a preset program, a ROM 42, and a RAM 43. A clock pulse generation circuit 144 and a frequency divider 145 for setting a reference clock pulse, a random number generator 146 and a sampling circuit 147 are connected to the CPU 41. In addition, as a means for random number sampling, you may comprise so that the sampling of a random number may be performed on the operation | movement program of CPU41.

The ROM 42 stores various control commands (commands) to be transmitted to the sub control circuit 82. As the command, for example, a command related to display control for the liquid crystal display device 5 is stored.

Examples of commands related to control on the liquid crystal display device 5 include an effect start command and an end effect command.
The effect start command is a command for causing the liquid crystal display device 5 to display an effect image when the rotation of the three rotary reels 3 is started. The end effect command is a command for causing the liquid crystal display device 5 to display an effect image when all three rotary reels 3 are stopped.

Also, commands relating to the setting or release of RB (regular bonus) and BB (big bonus) are also stored in the ROM 42, and the setting or release of RB or BB is notified to the sub-control circuit 82 by this command. It should be noted that data indicating that RB or BB is being executed may be included in various commands relating to display control for liquid crystal display device 5 instead of commands relating to setting or canceling RB or BB.

Various commands as described above are called from the ROM 42 by the CPU 41 and set in the RAM 43 when the predetermined condition is satisfied. The command set in the RAM 43 is supplied to the sub control circuit 82 at a predetermined timing. The sub control circuit 82 executes various processes based on the supplied command. The sub control circuit 82 does not input a command or the like to the main control circuit 81, and communication is performed in one direction from the main control circuit 81 to the sub control circuit 82.

The ROM 42 stores a symbol table for associating the rotational positions of the rotary reels 3L, 3C, and 3R with symbols drawn on the outer peripheral surface of the rotary reel, and a combination of symbols for winning. In addition, a winning symbol combination table in which a winning medal payout number is associated with a winning determination code representing the winning, a lottery table necessary for performing a lottery for determining an internal winning combination, and the like are stored.

In addition to the commands and tables described above, the RAM 43 stores variables relating to game progress such as the number of credits corresponding to the number of medals and a set value.

Major peripheral devices (actuators) whose operations are controlled by control signals from the microcomputer 40 include various lamps (1-BET lamp 9a, 2-BET lamp 9b, maximum BET lamp 9c, WIN lamp 17, and game medal insertion. A lamp 24, a game start display lamp 25), various display units (payout number display unit 18, medal accumulated number display unit 19, and accessory operation number display unit 20), and medal are stored. There are a hopper (including a payout driving unit) 50 for paying out a predetermined number of medals, and stepping motors 59L, 59C, 59R for rotating the rotary reels 3L, 3C, 3R.

Further, a motor drive circuit 49 for driving and controlling the stepping motors 59L, 59C and 59R, a hopper drive circuit 51 for driving and controlling the hopper 50, a lamp driving circuit 55 for driving and controlling various lamps, and a display for driving and controlling various display units. The unit drive circuit 58 is connected to the output unit of the CPU 41 via the I / O port 48. Each of these drive circuits receives a control signal such as a drive command output from the CPU 41, and controls the operation of each actuator.

The main input signal generators for generating input signals necessary for the microcomputer 40 to generate control commands include a start switch 6S, a 1-BET switch 11, a maximum BET switch 13, a stored medal settlement switch 14, There are an inserted medal sensor 22S, a reset switch 62, a setting key switch 63, a setting change switch 64, a reel stop signal circuit 56, a reel position detection circuit 60, and a payout completion signal circuit 61. These are also connected to the CPU 41 via the I / O port 48.

The setting key type switch 63 allows a setting value to be changed by inserting a predetermined key into this keyhole and turning it to the right. When the setting change switch 64 is pressed while the setting key switch 63 is capable of changing the setting value, the setting value changes. The setting key type switch 63 and the setting change switch 64 function as setting means for setting the probability of winning the winning combination step by step. The changed set value is stored in the RAM 43.

The start switch 6S detects the occurrence of an operation of the start lever 6. The inserted medal sensor 22 </ b> S detects a medal inserted into the medal slot 22. The reel stop signal circuit 56 generates a stop signal in response to the operation of each stop button 7L, 7C, 7R. With these operations, the decision button 26 and the cancel button 27 can switch the display screen of the liquid crystal display device 5 and input an instruction.

The reel position detection circuit 60 receives the pulse signal from the reel rotation sensor and transmits a signal for detecting the position of each of the rotating reels 3L, 3C, 3R to the CPU 41.
The payout completion signal circuit 61 generates a medal payout completion signal when the count value of the medal detection unit 50S (the number of medals paid out from the hopper 50) reaches a designated number. When the CPU 41 receives this medal payout completion signal, the driving of the hopper 50 is stopped via the hopper drive circuit 51 to complete the payout of medals. The medal detection unit 50S includes a medal sensor including a physical sensor for detecting medals paid out from the hopper 50, and can count the number of medals paid out by the medal sensor.

The random number generator 146 generates random numbers belonging to a certain numerical range, and the sampling circuit 147 samples one random number at an appropriate timing after the start lever 6 is operated. Based on the random numbers sampled in this way and the lottery table stored in the ROM 42, the CPU 41 as the winning combination determining means determines the internal winning combination.
After the internal winning combination is determined, random number sampling is performed again to select the “stop control table”.

After the rotation of the rotating reels 3L, 3C, 3R is started, the number of drive pulses supplied to each of the stepping motors 59L, 59C, 59R is counted, and the counted value is written in a predetermined area of the RAM 43. From the rotating reels 3L, 3C, 3R, reset pulses are obtained for each rotation, and these pulses are input to the CPU 41 via the reel position detection circuit 60. The count value of the drive pulse counted in the RAM 43 is cleared to “0” by the reset pulse thus obtained. As a result, the count value corresponding to the rotation position within one rotation range is stored in the RAM 43 for each of the rotation reels 3L, 3C, and 3R.

A symbol table is stored in the ROM 42 in order to associate the rotational positions of the rotating reels 3L, 3C, and 3R as described above with the symbols drawn on the outer peripheral surface of the rotating reel. In this symbol table, with reference to the rotational position at which the reset pulse is generated as described above, the code numbers sequentially given for each fixed rotation pitch of each rotary reel 3L, 3C, 3R, and the corresponding code number A symbol code indicating the symbol provided is associated with the symbol.

Furthermore, a winning symbol combination table is stored in the ROM 42. In this winning symbol combination table, a winning symbol combination, a winning medal dividend number, and a winning determination code representing the winning are associated with each other. The winning symbol combination table is referred to when the left rotating reel 3L, the central rotating reel 3C, and the right rotating reel 3R are controlled to stop and when winning confirmation after all reels are stopped.

When the winning combination is won internally by the lottery process (winning combination determination process) based on the random number sampling, the CPU 41 is sent from the reel stop signal circuit 56 at the timing when the player operates the stop buttons 7L, 7C, 7R. Based on the operation signal and the selected “stop control table”, a signal for stopping the reels 3L, 3C, 3R is sent to the motor drive circuit 49.

In the stop mode indicating that the winning combination of the internal winning combination is established, the CPU 41 supplies a payout command signal to the hopper drive circuit 51 when “payout” is selected by switching the stored medal settlement switch 14. A predetermined number of medals are paid out from the hopper 50. At this time, the medal detection unit 50S counts the number of medals to be paid out from the hopper 50, and when the count value reaches a designated number, a medal payout completion signal is input to the CPU 41. As a result, the CPU 41 stops driving the hopper 50 via the hopper drive circuit 51 and ends the “medal payout process”.
On the other hand, when “credit” is selected by switching the stored medal settlement switch 14, the number of medals to be paid out is stored in the RAM 43 as credits.

FIG. 5 is a diagram illustrating an example of symbols arranged on a reel.
Each reel 3L, 3C, 3R shows a symbol row in which 21 types of symbols are arranged. Each symbol is assigned a code number “00” to “20” and stored (stored) in the ROM 42. On each reel 3L, 3C, 3R, "white 7 (design 91)", "red 7 (design 92)", "bell (design 93)", "watermelon (design 94)", "Replay (design) 95) "," Upper Chile (symbol 96) ", and" Lower Chile (symbol 97) ". Each reel 3L, 3C, 3R is rotationally driven so that the symbol row moves in the direction of the arrow in FIG.

In this embodiment, there are provided BB, RB, replay, watermelon small part, bell small part, upper chile small part, lower chile small part, and JAC small part.

6 and 7 are diagrams showing the relationship among the combination, symbol combination, and the number of payouts.

The winning of BB is realized by arranging “white 7-white 7-white 7” along the effective line. When BB is won, 15 medals are paid out, and a transition is made to the BB gaming state.

Winning to RB is realized by arranging “red 7-red 7-red 7” along the active line. When RB is won, 15 medals are paid out, and the RB gaming state is entered.

Replay winning is realized by arranging “Replay-Replay-Replay” along the active line. When winning the replay, 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 allows a game to be performed without winning by inserting a game medium. However, when a replay is won in the BB gaming state, the RB gaming state is entered.

In addition, the combinations of symbols that will win the “Watermelon Minor”, “Bell Minor”, “Upper Chile Minor” and “Lower Chile Minor” are as shown. When each of the small combinations is won, the number of medals corresponding to each small combination shown in FIGS. 6 and 7 is paid out.

Here, “Upper Chile (symbol 96)” and “Lower Chile (symbol 97)” are stopped and displayed on the left reel 3L, respectively, for winning the “upper chile small part” and “lower chile small part” If you do it. Further, as shown in FIG. 5, the “upper dust” and the “lower dust” are arranged adjacent to each other on the left reel 3L. Accordingly, there may be a case where the winning combination of “upper part of upper Chile” and “small part of lower Chile” is established. In this case, the number of payouts is “9” or “15”.

The winning of the JAC small role is realized by arranging “Bell-Replay-Bell” in the RB gaming state.

In the general gaming state, there is no case where a JAC small part wins. In addition, in the BB gaming state, BB, RB and JAC small roles do not win. In addition, in the RB gaming state, no role other than the JAC small role is won.

8 and 9 are diagrams showing a lottery table.
As described above, the setting value can be set in six stages by operating the setting key switch 63 and the setting change switch 64. FIG. 8 is a lottery table used when the set value is “1”. FIG. 9 is a lottery table used when the set value is “6”. Although not shown, a lottery table used when the set value is any one of 2 to 5 also exists for each set value. As shown in FIG. 8 and FIG. 9, there are lottery tables in each gaming state of the general gaming state, the BB gaming state, the RB gaming state, and the RT (replay time) gaming state for each set value. The RT gaming state continues for 100 games after the BB gaming state ends. When 100 games are executed in the RT gaming state, the game state is shifted to the general gaming state. Each lottery table is stored in the ROM 42.
The probability of winning the “group role” is the probability of winning either an upper Chile small role, a lower Chile small role or a combined role of an upper Chile small role and a lower Chile small role.

As described above, the winning combination is determined based on the random number sampled by the sampling circuit 147 from the random numbers generated by the random number generator 146 and the lottery table. As shown in FIGS. 7 and 8, a random number range is stored in association with each winning combination in each gaming state. The random number extraction range of random numbers generated by the random number generator 146 is 0 to 16383, and the winning combination associated with the random number value acquired by the sampling circuit 147 is determined as the winning combination. For example, when the set value is “1” and the random number value sampled by the sampling circuit 147 in the general gaming state is “1000”, “Replay” is determined as the winning combination. The winning probability for each winning combination is determined by the size of the random number range.

In this embodiment, as shown in FIGS. 7 and 8, in all gaming states, the winning probability for each winning combination other than BB and RB is “6” when the set value is “1”. The case is the same. The winning probability for each winning combination other than BB and RB is set to the same value even when the set value is 2 to 5. For example, in the BB gaming state, the winning probability for the small part of the bell is 4000/16384 regardless of the set value.

On the other hand, the winning probability for BB and RB is 60/16384 when the set value is “1”, and 80/16384 when the set value is “6”. The winning probabilities for BB and RB are set to different values even when the set values are 2 to 5, and the higher the set value, the higher the winning probability for BB and RB. Is set. Therefore, the player is more likely to acquire a larger number of medals as he plays with a gaming machine having a higher set value.

FIG. 10 is a flowchart showing a game execution process performed in the main control circuit.
First, the CPU 41 determines whether or not there is a request for automatic insertion of medals (step S120). The case where there is a request for automatic insertion is a case where a winning of replay (replay) is established in the previous game. When there is a request for automatic insertion of medals, medals for the insertion request are automatically inserted (step S122), and a medal insertion command is transmitted to the sub-control circuit 82 (step S123).

On the other hand, when determining in step S120 that there is no request for automatic medal insertion, the CPU 41 determines whether or not a medal has been inserted (step S121). That is, the CPU 41 determines whether or not a detection signal issued by the insertion medal sensor 22S that has detected that a medal has been inserted into the medal insertion slot 22 has been received, or whether the BET switch (1-BET switch 11 or maximum BET switch 13). ) To determine whether or not a medal has been inserted. When it is determined that a detection signal issued by the BET switch (1-BET switch 11 or maximum BET switch 13) is received, the CPU 41 corresponds to the number of medals bet from the number of credits stored in the RAM 43. A process of subtracting the number of credits is performed.

When determining in step S121 that no medal has been inserted, the CPU 41 returns the process to step S120.
If it is determined in step S121 that a medal has been inserted, or if the process of step S123 is executed, the CPU 41 determines whether or not the start lever 6 has been operated (step S124). That is, the CPU 41 determines whether or not an input signal from the start switch 6S has been received.

When determining in step S124 that the start lever 6 has not been operated, the CPU 41 returns the process to step S120. On the other hand, when determining in step S124 that the start lever 6 has been operated, the CPU 41 performs processing related to various settings (step S125). Various setting processes will be described later with reference to FIG.
After executing the process of step S125, the CPU 41 shifts the process to step S126.

In step S <b> 126, the CPU 41 sets an effect start command in the RAM 43. This effect start command is a command for starting display of a predetermined effect image on the liquid crystal display device 5 and includes data on the internal winning combination determined by the lottery process. The effect start command is supplied to the sub control circuit 82 at a predetermined timing.
After executing the process of step S126, the CPU 41 shifts the process to step S128.

In step S128, the CPU 41 determines whether or not the stop button 7 (7L, 7C, 7R) is “ON” based on the presence / absence of an input signal from the reel stop signal circuit 56 (step S128). When it is determined that the stop button 7 is not “ON”, the CPU 41 determines whether or not the value of the automatic stop timer is “0” (step S129), and when it is determined that the value is not “0”. The process returns to step S128.

On the other hand, if it is determined in step S128 that the stop button 7 is “ON”, or if it is determined in step S129 that the value of the automatic stop timer is “0”, the CPU 41 corresponds to the stop button 7. The rotation of the rotating reel 3 is stopped. At that time, the winning request (internal winning combination), the symbol position (the rotating position of the rotating reel 3 at the time of operation), the selected stop control table, etc. The number of frames is determined (step S130).

Next, the CPU 41 performs a process of rotating and stopping the rotating reel 3 by the number of sliding frames determined in step S130 (step S131), and sets a stop request for one rotating reel 3 (step S132). .

Next, the CPU 41 determines whether or not all of the three rotary reels 3 (3L, 3C, 3R) have been stopped (step S135). If it is determined that all the rotating reels 3 are not stopped, the process returns to step S128. On the other hand, if it is determined that all the rotating reels 3 have stopped, the CPU 41 performs a winning search (step S136). At this time, a winning symbol combination table or the like stored in the ROM 42 is referred to. Further, it is determined whether or not the winning flag is normal. If not, the illegal error may be displayed and the process may be interrupted.

Next, the CPU 41 sets an end effect command in the RAM 43 (step S137). This end effect command is a command for displaying an effect image at the end of the game according to the game result, and includes data related to the result of the winning search in step S136. The end effect command is supplied to the sub control circuit 82 at a predetermined timing.

Next, the CPU 41 determines whether or not a medal has been paid out, that is, whether or not there is a winning number (step S138).
When determining that there is a medal payout, the CPU 41 stores or pays out the number of medals according to the gaming state and the winning combination (step S139). When storing medals, the CPU 41 performs a process of adding the number of credits stored in the RAM 43. On the other hand, when paying out medals, the CPU 41 sends out a payout command signal to the hopper driving circuit 51 and pays out a predetermined number of medals from the hopper 50. At that time, the medal detection unit 50S counts the number of medals to be paid out from the hopper 50, and when the count value reaches a designated number, a medal payout completion signal is input to the CPU 41. As a result, the CPU 41 stops driving the hopper 50 via the hopper drive circuit 51 and ends the medal payout process.

Next, the CPU 41 determines whether or not an RB has been won (step S140). If it is determined that RB has been won, the CPU 41 performs processing related to RB setting (step S141). In this step S141, the CPU 41 performs processing related to setting of the RB lottery probability table and the RB winning symbol combination table. In step S141, the CPU 41 starts counting the number of RB game winnings and the like, and starts a process of displaying the count value on the accessory operation count display unit 20. After executing the process of step S141, the CPU 41 shifts the process to step S142.

In step S <b> 142, the CPU 41 sets an RB setting command in the RAM 43. The RB setting command is a command for causing the liquid crystal display device 5 to display an RB effect image as a screen image, and is supplied to the sub-control circuit 82 at a predetermined timing.

When it is determined in step S140 that the RB has not been won or when the process of step S142 is executed, the CPU 41 determines whether or not the BB has been won (step S143). If it is determined that BB has been won, the CPU 41 performs processing related to BB setting (step S144). In step S144, the CPU 41 performs processing related to setting of a BB lottery probability table, a BB winning symbol combination table, and the like. In step S146, the CPU 41 starts counting the number of times the BB game is consumed, displaying the count value on the accessory action number display unit 20, counting the number of medals paid out, and the like.
Thereafter, the CPU 41 shifts the processing to step S145.

In step S145, the CPU 41 sets a BB setting command in the RAM 43. The BB setting command is a command for causing the liquid crystal display device 5 to display an effect image for BB as a screen image, and is supplied to the sub-control circuit 82 at a predetermined timing.

When it is determined in step S143 that the BB has not been won or when the process of step S145 is executed, the CPU 41 determines whether or not the RB has ended (step S146). If it is determined that the RB has ended, the CPU 41 next performs a process related to the RB setting cancellation (step S147). In step S148, the CPU 41 changes from the RB lottery probability table set in the process of step S141, the RB winning symbol combination table, or the like to the lottery probability table used for the normal gaming state (other than RB or BB). Performs processing related to setting change. Thereafter, the CPU 41 shifts the processing to step S148.

In step S <b> 148, the CPU 41 sets an RB release command in the RAM 43. The RB release command is a command for stopping the display of the effect image for RB as the screen image and causing the liquid crystal display device 5 to display a normal effect image (other than RB or BB). The RB release command is supplied to the sub control circuit 82 at a predetermined timing.

If it is not determined in step S146 that the RB has ended, or if the process of step S148 is executed, the CPU 41 determines whether the BB has ended (step S149). If it is determined that the BB has ended, the CPU 41 then performs a process related to the BB setting cancellation (step S150). In step S150, the CPU 41 sets the lottery probability table used for the normal gaming state (other than RB or BB) from the BB lottery table or the BB winning symbol combination table set in the process of step S144. Process related to change.
Thereafter, the CPU 41 moves the process to step S151.

In step S <b> 151, the CPU 41 sets a BB release command in the RAM 43. The BB release command is a command for stopping the display of the effect image for BB as the screen image and causing the liquid crystal display device 5 to display a normal effect image (other than RB or BB). The BB release command is supplied to the sub control circuit 82 at a predetermined timing.
If it is determined in step S149 that the RB has not ended, or if the process of step S151 is executed, the CPU 41 performs a setting change process (step S160). The setting change process will be described later with reference to FIG. After the process of step S160 is completed, this subroutine is terminated.

FIG. 11 is a flowchart showing various setting processes. Various setting processes are called and executed in step S125 of the game execution process shown in FIG.
First, the CPU 41 determines whether or not the value of “balance setting game count” stored in the RAM 43 is “0” (step S501). “Balance setting game number of times” is based on a lottery table (see FIG. 9) corresponding to setting 6 regardless of setting values preset by setting key type switch 63 and setting change switch 64 as setting means. It is the remaining number of times that can be played. In the lottery table corresponding to setting 6, the winning probability for BB and RB is set higher than that for the lottery tables corresponding to other setting values. Therefore, by playing a game based on the lottery table corresponding to setting 6, the player can advance the game advantageously. The value of the “balance setting game count” is “50” when the winning combination “watermelon” is won internally, and decreases by one each time a game is played.

When the value of the “balance setting game count” is “0” (step S501: YES), the lottery table corresponding to the preset setting value is referred to (step S502). That is, a game is played based on the lottery table corresponding to the setting values set by the setting key switch 63 and the setting change switch 64 as setting means. On the other hand, when the value of the “balance setting game count” is not “0” (step S501: NO), the lottery table corresponding to the setting 6 is referred to regardless of the preset setting value (step S503). The value of “set number of games” is decreased by 1 (step S504). That is, a game is played based on the lottery table corresponding to the setting 6, regardless of the setting values set by the setting key switch 63 and the setting change switch 64 as the setting means. As a result, while the value of the “balance setting game count” is a value other than “0”, the winning combination is performed with the setting value changed to 6. In the process of step S503, the CPU 41 functions as a setting change unit.
After the process of step S502 or step S504 is completed, the process proceeds to step S511.

In step S <b> 511, the CPU 41 samples a random number from the random number generator 146 and acquires a random number value of 1 from 0 to 16383. The acquired random number value is stored in the RAM 43 (step S512), and a winning combination is determined based on the lottery table referred to in step S502 or step S504 (step S513). For example, if the referenced lottery table is a general gaming state lottery table corresponding to setting 6 shown in FIG. 9 and the obtained random number value is “100”, RB is determined as the winning combination. At this time, the CPU 41 functions as a winning combination determining means. After the process of step S513 is complete | finished, a process is moved to step S514.

In step S514, the CPU 41 executes other processing. Here, the CPU 41 performs a win lamp lighting lottery process, a process related to selection of a stop control table for stopping the rotating reel, and a process for initializing for reel rotation, and rotates the rotating reel 3 (3L, 3C, 3R). To start.
After the rotation of the rotating reels 3L, 3C, 3R is started, the number of drive pulses transmitted to each of the stepping motors 59L, 59C, 59R is counted, and the counted value is stored in the RAM 43. A reset pulse is obtained for each rotation from the rotating reels 3L, 3C, 3R, and these pulses are input to the CPU 41 via the reel position detection circuit 60. The count value is cleared to “0” in the drive pulse counted in the RAM 43 by the reset pulse thus obtained. By doing so, the RAM 43 stores the count value corresponding to the rotational position within one rotation range for each of the rotating reels 3L, 3C, 3R.

Further, in the symbol table stored in the ROM 42 in order to associate the rotational positions of the rotating reels 3L, 3C, and 3R with the symbols drawn on the outer peripheral surface of the rotating reel, the rotational position at which the reset pulse is generated is used as a reference. A code number that is sequentially given for each of the rotation reels 3L, 3C, and 3R and a symbol code indicating a symbol that is provided for each code number are associated with each other. Further, the winning symbol combination table stored in the ROM 42 is referred to when controlling the rotation of each of the rotating reels 3L, 3C, 3R and when confirming the winning after stopping all the rotating reels.
After the process of step S514 is completed, this subroutine is terminated.

FIG. 12 is a flowchart showing the setting change process. The setting change process is a process that is called and executed in step S160 of the game execution process shown in FIG.
First, the CPU 41 determines whether or not the winning combination determined in step S513 of the various setting processes shown in FIG. 11 is “watermelon” (step S401). If the winning combination is “watermelon” (step S401: YES), the value of “balance setting game count” is set to 50. As described above, the “balance setting game count” is the remaining number of times that a game can be played based on a lottery table (see FIG. 9) corresponding to setting 6 regardless of a preset setting value. is there. By performing the processing of step S401 and step S402, when “watermelon” is won internally, the game is played based on the lottery table corresponding to the setting value 6 for the next 50 games regardless of the preset setting value. Will be.
When the winning combination is not “watermelon” (step S401: NO) or after the process of step S402 is completed, this subroutine is terminated.

FIG. 13 is a flowchart showing a subroutine of command reception processing performed in the sub control circuit.
First, the sub CPU 206 determines whether or not an effect start command has been received (step S200). If it is determined that an effect start command has not been received, the process proceeds to step S210.
On the other hand, if it is determined that an effect start command has been received, in step S201, the sub CPU 206 selects an effect pattern corresponding to the command from a plurality of types of effect patterns stored in the program ROM 208.
If the RB flag is set, the sub CPU 206 selects an effect pattern for RB. If the BB flag is set, an effect pattern for BB is selected. Next, in step S202, effect pattern data, which is data indicating the effect pattern, is supplied to the display control circuit 250. After executing the process of step S202, the process proceeds to step S210.

In step S210, the sub CPU 206 determines whether or not an end effect command has been received. If it is determined that the end effect command has not been received, the process proceeds to step S220.
On the other hand, when determining that the end effect command has been received, in step S211, the sub CPU 206 selects an end effect pattern corresponding to the command from a plurality of types of end effect patterns stored in the program ROM 208.
Next, in step S212, end effect pattern data is supplied to the display control circuit 250. After performing the process of step S210, the process proceeds to step S220.

In step S220, the sub CPU 206 determines whether or not an RB setting command has been received. If it is determined that the RB setting command has not been received, the process proceeds to step S230. On the other hand, when determining that the RB setting command has been received, the sub CPU 206 sets the RB flag in step S221. After performing the process of step S221, the process proceeds to step S230. The RB flag is a flag that is set when the RB starts and cleared when the RB ends.

In step S230, the sub CPU 206 determines whether or not a BB setting command has been received. If it is determined that the BB setting command has not been received, the process proceeds to step S240. On the other hand, when determining that the BB setting command is received, the sub CPU 206 sets the BB flag in step S231. The BB flag is a flag that is set when the BB starts and cleared when the BB ends.

If it is determined in step S230 that the BB setting command has not been received, or if the process of step S231 has been executed, the sub CPU 206 determines whether or not an RB release command has been received (step S240). If it is determined that the RB release command has been received, the RB flag is cleared (step S241).

If it is determined in step S240 that an RB release command has not been received, or if the process of step S241 has been executed, the sub CPU 206 determines whether or not a BB release command has been received (step S250). If it is determined that the BB release command has not been received, this subroutine is terminated. On the other hand, if it is determined that the BB release command has been received, the BB flag is cleared (step S251), and this subroutine is terminated.

FIG. 14 is a flowchart showing a subroutine of display control processing performed in the display control circuit.
The VDP 212 generates a screen image corresponding to various data supplied from the sub CPU 206.
When the VDP 212 does not receive the production pattern data from the sub CPU 206 (step S300: NO), the VDP 212 extracts the demo image from the image data ROM 216 and stores it in the buffer (step S301).

The VDP 212 receives the effect pattern data from the sub CPU 206 (step S300: YES). When the VDP 212 does not receive the end effect pattern data (step S304: NO), the effect image is extracted from the image data ROM 216. And stored in the buffer (step S305).

The VDP 212 receives the effect pattern data supplied from the sub CPU 206 (step S300: YES). When the end effect pattern data is supplied (step S304: YES), the VDP 212 extracts the effect image at the end from the image data ROM 216. And stored in the buffer (step S306).
After executing the processing of step S301, S305, or S306, the VDP 212 outputs a screen image to the liquid crystal display device 5 at every predetermined timing (for example, every 1/30 seconds) (step S308).

Thereafter, when the effect has not ended (step S310: NO), the process returns to step S300. On the other hand, when the effect is finished (step S310: YES), the pattern data is cleared (step S311), and the process returns to step S300.

As described above, according to the pachi-slot gaming device 1 of the present embodiment, when the “watermelon” is won internally, the setting is different from the preset value by the setting key type switch 63 and the setting change switch 64 as the setting means. Play a game based on the value. Thereby, the winning probability for BB and RB is changed during the game by changing the set value that determines the probability of winning the winning combination according to the internal winning combination. This makes it possible to provide a gaming machine that can improve the interest of the game.

In the present embodiment, when the lottery table to be referred to is the lottery table corresponding to the setting 6 when the “watermelon” is internally won, the winning probability for BB and RB is increased. However, the present invention is not limited to this, and the probability of winning a specific winning combination may be reduced by internally winning a predetermined winning combination. For example, when a lottery table to be referred to is a lottery table corresponding to a setting value that is one lower than a preset setting value when “watermelon” is internally won, the winning probability for BB and RB is reduced. It is good.
In addition, the lottery table to be referred to when the “watermelon” is internally won is set as the lottery table corresponding to the setting 6, while the lottery table to be referred to when the “Replay” is internally hit is the lottery table corresponding to the setting 1. As described above, there are a plurality of types of predetermined winning combinations, and the content of the change in the set value may differ depending on the type of the predetermined winning combination determined by the winning combination determining means.

In the present embodiment, the lottery table to be referred to is set to the lottery table corresponding to the setting 6 for 50 games after the “watermelon” is won internally. The period in which the set value is changed in the present invention. Is not particularly limited. For example, a setting value that has been changed once may continue to be played with the changed setting value until the setting value is changed next time.

In the present embodiment, the case where the predetermined winning combination whose setting value is changed by winning is “watermelon” has been described, but the predetermined winning combination is not particularly limited in the present invention. Other winning combinations may be used.

In the present embodiment, the winning combinations having different winning probabilities for each set value are BB and RB. However, the present invention is not limited to this, and may be other winning combinations, for example, Further, the winning probabilities of all winning combinations may be different for each set value.

In the present embodiment, the case where the present invention is applied to a pachislot gaming machine has been described, but the present invention can also be applied to other gaming machines (such as slot machines).
