[Configuration of data table stored in main ROM]
This completes the description of the circuit configuration of the pachislot machine 1. Next, the configuration of various data tables stored in the main ROM 32 will be described with reference to FIGS.

[Random value extraction timing determination table]
The random value extraction timing determination table will be described with reference to FIG. The random value extraction timing determination table defines extraction timing values (seconds) according to lottery values. The extraction timing value is data acquired as a result of lottery performed with reference to the random value extraction timing determination table. Specifically, it is data for determining the extraction timing of the second random number value by a random value extraction timing determination process (see FIG. 19 described later) based on the first random number value, and the start lever 6 is operated. To the time from when the second random number value is extracted.

  In the present embodiment, the first random number value extracted from the predetermined numerical range “0 to 65535” is sequentially subtracted by the lottery value corresponding to each winning number, and whether or not the result of the subtraction becomes negative A lottery is performed by determining whether or not.

  Here, since the lottery values defined in the random value extraction timing determination table are “8192”, each extraction timing value is won with the same probability. This extraction timing value is defined between 0.05 seconds and 0.40 seconds, and the second random number value is extracted after the reels 3L, 3C, 3R start rotating at S5 in FIG. This is performed until the rotation speeds of 3L, 3C, and 3R reach a constant speed.

[Design arrangement table]
The symbol arrangement table will be described with reference to FIG. The symbol arrangement table defines the position of each symbol in the rotation direction of each reel 3L, 3C, 3R and data (hereinafter, symbol code) specifying the type of symbol arranged at each position.

  In the symbol arrangement table, when the reel index is detected, the symbol positions existing in the middle stages of the display windows 21L, 21C, and 21R are set to “0”, and the symbols are arranged in the order of advance in the rotation direction of the reels 3L, 3C, and 3R. “0” to “20” are respectively assigned to the positions. Therefore, by managing how many symbols have been rotated since the reel index was detected, by referring to the symbol arrangement table, the positions of symbols existing mainly in the middle stages of the display windows 21L, 21C, and 21R and It is possible to always manage the type of the symbol.

[Design combination table]
The symbol combination table will be described with reference to FIG. In the present embodiment, when the symbol combination displayed by the reels 3L, 3C, 3R along the winning determination line matches the symbol combination defined by the symbol combination table, it is determined to be a prize, Benefits such as paying out medals, re-game operations, and bonus game operations are given to the player.

  The symbol combination table defines a symbol combination, a display combination, and a payout number that are predetermined according to the type of privilege. The display combination is data for identifying a combination of symbols displayed along the winning determination line.

  The display combination is represented as 1-byte data in which a unique symbol combination is assigned to each bit. For example, when the symbol “bell” of each reel 3L, 3C, 3R is displayed along the winning determination line, “bell (00000010)” is determined as the display combination.

  Further, when a numerical value of 1 or more is determined as the payout number, medals are paid out. In the present embodiment, when a cherry, bell, or watermelon is determined as a display combination, medals are paid out. The number of payouts is defined according to the number of inserted sheets. Basically, a larger number of paid-out sheets is determined when the number of inserted sheets is small.

  In addition, when replay is determined as the display combination, replaying is performed. When BB is determined as the display combination, the bonus is activated. If the symbol combination displayed along the winning determination line does not match any of the symbol combinations defined by the symbol combination table, it is a so-called “losing”.

[Bonus operating table]
With reference to FIG. 9, the bonus operation time table will be described. The bonus operation time table defines data to be stored in various storage areas provided in the main RAM 33 when the bonus operation is performed.

  The in-operation flag is data for identifying the type of bonus that is activated. In the present embodiment, BB (a combination continuous action device related to a first type special combination) and RB (a first type special combination) are provided as bonus types. The operation of RB is continuously performed while the operation of BB is performed.

  The operation of BB is ended when the medals are paid out to reach the prescribed number (346 in the present embodiment). The RB is activated when a game that reaches the specified number of times (8 times in the present embodiment) is performed, when there is a winning that reaches the specified number of times (8 times in the present embodiment), or BB The operation ends when either of the operations ends. The bonus end number counter, the possible game number counter, and the possible winning number counter are data for managing whether or not the specified number of times or the specified number of times as a trigger end timing of the bonus has been reached.

  More specifically, numerical values defined by the bonus operation time table are stored in the respective counters, and the subtraction is performed through the operation of the bonus. As a result, the operation of the corresponding bonus is completed on condition that the value of each counter is updated to “0”.

[Internal lottery table]
The internal lottery table will be described with reference to FIGS. 10 and 11. The internal lottery table defines a data pointer and a lottery value according to the winning number. The data pointer is data acquired as a result of lottery performed with reference to the internal lottery table, and is data for designating an internal winning combination defined by an internal winning combination determination table described later. The data pointer is provided with a small role / replay data pointer and a bonus data pointer.

  In the present embodiment, a range of numerical values predetermined after the elapse of the extraction timing time corresponding to the extraction timing value determined based on the first random number value by a random value extraction timing determination process (see FIG. 19) described later. The second random number value extracted from “0 to 65535” is sequentially subtracted with the lottery value corresponding to each winning number, and whether or not the result of the subtraction becomes negative (whether or not a so-called “digit” has occurred). An internal lottery is performed by making the above determination.

  Therefore, the larger the numerical value defined as the lottery value, the higher the probability that the data (that is, the data pointer) to which it is assigned will be determined. The winning probability of each winning number can be expressed by “the lottery value corresponding to each winning number / the number of all second random number values that may be extracted (65536)”.

  FIG. 10 shows an internal lottery table for a general gaming state. FIG. 11 shows the internal lottery table for RB operation. In the present embodiment, depending on the situation such as whether or not the bonus is activated, the type of internal winning combination and the winning probability that are determined are varied by using different types of internal lottery tables. , The expectation that the player holds is undulating.

[Internal winning combination determination table]
The internal winning combination determination table will be described with reference to FIGS. The internal winning combination determination table defines an internal winning combination in accordance with the data pointer. When the data pointer is determined, the internal winning combination is uniquely acquired.

  The internal winning combination is data for identifying a combination of symbols of each reel 3L, 3C, 3L that is permitted to be displayed along the winning determination line. Like the display combination, the internal winning combination is represented as 1-byte data in which a unique symbol combination is assigned to each bit. When the data pointer is “0”, the content of the internal winning combination is “lost”, which indicates that any display of symbol combinations defined by the symbol combination table described above is not permitted.

  FIG. 12 shows a small combination / replay internal winning combination determination table. The small winning combination / replay internal winning combination determination table defines an internal winning combination relating to the payout of medals or an internal winning combination relating to the operation of replay. FIG. 13 shows a bonus internal winning combination determination table. The bonus internal winning combination determination table defines internal winning combinations related to the operation of the bonus.

In this process, the internal winning combination is determined by lottery based on the second random value extracted based on the extraction timing value determined in the random number extraction timing determination process. Next, the main CPU 31 transmits a start command to the sub-control circuit 72 (S8). The start command includes a parameter for specifying an internal winning combination.

  Next, the main CPU 31 performs a reel stop control process which will be described later with reference to FIG. 22 (S9). In this process, the input of the stop switch 7S is checked, and the rotation of the corresponding reel is stopped based on the timing when the stop button is pressed and the internal winning combination.

  Next, the main CPU 31 searches for a combination of symbols displayed along the winning determination line, and determines the number of payouts and the like based on the result (S10. As a result of the search, displayed along the winning determination line). When the symbol combination matches the symbol combination defined by the symbol combination table (see FIG. 8), the corresponding display combination and the number of payouts are determined.The main CPU 31 then issues a display command to the sub-control circuit. (S11) The display command includes parameters for specifying the display combination, the number of payouts, and the like.

  Next, the main CPU 31 performs medal payout processing (S12). In this process, the hopper 40 is driven and the number of credits is updated based on the determined payout number. Next, the main CPU 31 updates the bonus end number counter based on the payout number (S13). In this process, the numerical value determined as the payout number is subtracted from the bonus end number counter.

  Next, the main CPU 31 determines whether or not the bonus operating flag is on (S14). When determining that the bonus operating flag is on, the main CPU 31 performs a bonus end check process which will be described later with reference to FIG. 24 (S15). In this process, it is checked whether or not to end the operation of the bonus with reference to various counters for managing the end timing of the bonus.

  The main CPU 31 performs a bonus operation check process which will be described later with reference to FIG. 23 after S15 or when it is determined in S14 that the bonus operating flag is not on (S16). In this process, it is checked whether or not the bonus operation is started. When this process ends, the process proceeds to S2.

[Medal reception / start check processing]
Next, the medal acceptance / start check process will be described with reference to FIG. First, the main CPU 31 determines whether or not the automatic insertion number counter is 0 (S31). When it is determined that the automatic insertion number counter is 0, the medal passage permission is performed (S32). In this process, the solenoid of the selector 42 is driven, and the passage of medals in the selector 42 is prompted.

  When determining that the automatic insertion number counter is not 0, the main CPU 31 copies the automatic insertion number counter to the insertion number counter (S33). Next, the main CPU 31 clears the automatic insertion number counter (S34). S33 and S34 are processes for replaying.

  After S32 or S34, the main CPU 31 sets 3 as the maximum value of the insertion number counter (S35). Next, the main CPU 31 determines whether or not the bonus operating flag is on (S36). When determining that the bonus operating flag is on, the main CPU 31 changes the maximum value of the insertion number counter (S37). In this process, for example, the maximum value is changed to 2.

  The main CPU 31 determines whether or not the passage of medals has been detected after S37 or when it is determined in S36 that the bonus operating flag is not on (S38). When determining that the passage of medals has been detected, the main CPU 31 determines whether or not the inserted number counter has reached the maximum value (S39). When determining that the inserted number counter has not reached the maximum value, the main CPU 31 adds 1 to the inserted number counter (S40). Next, the main CPU 31 transmits a medal insertion command to the sub control circuit 72 (S41). The medal insertion command includes a parameter for specifying the number of inserted coins.

  When the main CPU 31 determines in S39 that the inserted number counter is the maximum value, the main CPU 31 adds 1 to the credit counter (S42). The main CPU 31 checks the bet switch 11S after S42, after S41, or when it is determined that the passage of medals is not detected in S38 (S43). In this process, a numerical value corresponding to the bet button 11 is added to the inserted number counter while being subtracted from the credit counter.

  Next, the main CPU 31 determines whether or not the insertion number counter has reached the maximum value (S44). When it is determined that the insertion number counter has not reached the maximum value, the process proceeds to S38, whereas when it is determined that the insertion number counter has reached the maximum value, it is determined whether or not the start switch 6S is on (S45). ).

  When determining that the start switch 6S is not on, the main CPU 31 proceeds to S38, whereas when determining that the start switch 6S is on, the main CPU 31 prohibits medal passage (S46). In this process, the solenoid of the selector 42 is not driven, and medals are expelled. When this process ends, the medal acceptance / start check process ends.

[Random value extraction timing decision processing]
Next, the random value extraction timing determination process will be described with reference to FIG. First, the main CPU 31 acquires the first random value stored in the first random value storage area, and sets it as a second random number extraction timing random value (S51).

  Next, the main CPU 31 performs lottery of the extraction timing value of the second random number value based on the set random number value for extraction timing of the second random value value based on the random value extraction timing determination table (see FIG. 6) (S52). .

  Next, the main CPU 31 stores the extraction timing value determined by the lottery in S52 in the second random value extraction timing storage area (S53). When this process ends, the random value extraction timing determination process ends.

[Internal lottery processing]
Next, an internal lottery process will be described with reference to FIG. First, the main CPU 31 determines an internal lottery table (see FIGS. 10 and 11) and the number of lotteries (S61). The operating flag storage area (see FIG. 16) is referred to, and the internal lottery table and the number of lotteries are determined according to whether or not the bonus is activated. The number of lotteries indicates the number of times that a lottery value is subtracted and a determination is made as to whether a digit has occurred for each winning number defined by the internal lottery table.

  Next, the main CPU 31 performs random value extraction weight processing which will be described later with reference to FIG. 21 (S62). In this process, the second random number value is extracted after the extraction timing time corresponding to the extraction timing value determined in the random value extraction timing determination process (see FIG. 19) has passed, and this second random number value is stored in the second random number value. Store in the area. Next, the main CPU 31 obtains the second random number value stored in the second random value storage area and sets it as a determination random value (S63). Next, the main CPU 31 sets 1 as the initial value of the winning number (S64).

  Next, the main CPU 31 refers to the internal lottery table and acquires a lottery value corresponding to the winning number (S65). Next, the main CPU 31 subtracts the lottery value from the determination random number value (S66). Next, the main CPU 31 determines whether or not a digit has been taken (S67). When the main CPU 31 determines that the digit is not performed, the main CPU 31 subtracts 1 from the number of lotteries and adds 1 to the winning number (S68).

  Next, the main CPU 31 determines whether or not the number of lotteries is 0 (S69). When the main CPU 31 determines that the number of lotteries is not 0, the process proceeds to S65. On the other hand, when the number of lotteries is determined to be 0, the main CPU 31 sets 0 as the small role / replay data pointer and serves as the bonus data pointer. 0 is set (S70).

  When the main CPU 31 determines in S67 that a digit has been made, the main CPU 31 acquires a small role / replay data pointer and a bonus data pointer according to the current winning number (S71). After S71 or S70, the main CPU 31 refers to the small combination / replay internal winning combination determination table (see FIG. 12) and acquires the internal winning combination based on the small combination / replay data pointer (S72).

  Next, the main CPU 31 stores the acquired internal winning combination in the internal winning combination storing area (see FIG. 14) (S73). Next, the main CPU 31 determines whether or not the data stored in the carryover combination storage area (see FIG. 15) is 0 (S74). When the main CPU 31 determines that the data stored in the carryover combination storage area is 0, the main CPU 31 refers to the bonus internal winning combination determination table (see FIG. 12), and determines the internal winning combination based on the bonus data pointer. Is acquired (S75). Next, the main CPU 31 stores the acquired internal winning combination in the carryover combination storing area (S76).

  When the main CPU 31 determines that the data stored in the carryover combination storage area (see FIG. 15) is not 0 after S76 or in S74, the carryover combination storage area and the internal winning combination storage area (see FIG. 14). And the result is stored in the internal winning combination storing area (S77). That is, the internal winning combination relating to the bonus operation is carried over. When this process ends, the internal lottery process ends.

[Random value extraction weight processing]
Next, the random value weight processing will be described with reference to FIG. First, the main CPU 31 determines whether or not the extraction timing time corresponding to the extraction timing value stored in the second random value extraction timing storage area has passed (S81). When determining that the extraction timing time corresponding to the extraction timing value stored in the second random value extraction timing storage area has not elapsed, the main CPU 31 performs a wait process (S82). In this process, the next process is not executed until the extraction timing time corresponding to the extraction timing value stored in the second random value extraction timing storage area has elapsed. Specifically, the extraction timing time corresponding to the extraction timing value stored in the second random value extraction timing storage area is 0.40 (seconds), and after the start lever 6 is operated, the process of S81 is performed. If only 0.30 seconds have elapsed before the process is performed, a process that does not execute the next process is performed until 0.40 seconds elapse after the start lever 6 is operated.

  When determining that the extraction timing time corresponding to the extraction timing value stored in the second random number value extraction timing storage area has elapsed after S82 or in S81, the main CPU 31 extracts the second random number value. And stored in the second random value storage area. When this process ends, the random value extraction weight process ends.

  Here, the process from the extraction of the first random number value until the internal winning combination is determined by the second random number value will be described.

  First, in S45 of FIG. 18, when the start switch 6S is turned on, that is, when the player operates the start lever 6, the first random number value among the random numbers generated from the random number generator 36 is used. Is extracted (S4 in FIG. 17). Next, an extraction timing value for determining a timing time for extracting the second random number value based on the first random value extracted with reference to the random value extraction timing determination table (see FIG. 6) is determined by lottery ( S52 of FIG. 19).

  Next, it is determined whether or not the extraction timing time corresponding to the determined extraction timing value has elapsed since the start lever 6 was operated, and among the random numbers generated from the random number generator 36 after the extraction timing time has elapsed. A second random value is extracted (S83 in FIG. 21). Then, a lottery is performed using the extracted second random number value as a determination random number value (S63 in FIG. 20), and an internal winning combination is determined (S75 in FIG. 20).

  For this reason, it can be varied by delaying the timing of extracting the second random number value for determining the internal winning combination by the extraction timing value determined based on the first random number value. Therefore, compared to the case where a random number value for determining the internal winning combination is extracted at the timing when the player operates the start lever 6, it is difficult to predict the random number extraction timing, and the game is played illegally. Can be prevented.

[Reel stop control process]
Next, the reel stop control process will be described with reference to FIG. First, the main CPU 31 determines whether or not a valid stop button has been pressed (S101). When the main CPU 31 determines that a valid stop button has not been pressed, it waits until it is pressed.

  When determining that a valid stop button has been pressed, the main CPU 31 invalidates the operation of the corresponding stop button (S102). The valid and invalid states of the stop buttons 7L, 7C, and 7R are managed in a predetermined storage area provided in the main RAM 33.

  Next, the main CPU 31 sets 5 as the number of checks (S103). In the present embodiment, since the maximum number of sliding symbols is “4”, when the stop button is pressed, including the symbol position in the middle of the corresponding display window, Up to the position is subject to check. That is, any of the five numerical values “0”, “1”, “2”, “3”, and “4” is determined as the number of sliding frames.

  Next, based on the internal winning combination, the main CPU 31 includes each position within the range of the number of checks including the position of the symbol in the middle of the corresponding display window (hereinafter referred to as the stop start position) when the stop button is pressed. Among the symbol positions, the symbol position with the highest priority is searched (S104). In this process, the position of the symbol that can display the combination of symbols permitted to be displayed by the internal winning combination along the winning determination line is determined as the position of the symbol with the highest priority.

  Next, the main CPU 31 determines the number of sliding symbols based on the search result (S105). The number of symbols from the stop start position to the symbol position with the highest priority is determined as the number of sliding symbols. Next, the main CPU 31 shifts to waiting for a scheduled stop position (S106). When shifting to waiting for the planned stop position, the driving of the stepping motors 49L, 49C, 49R is controlled by an interrupt process to be described later, and the reels wait for the position of the symbol with the highest priority to reach the middle stage of the corresponding display window. The rotation of is stopped.

  Next, the main CPU 31 transmits a reel stop command to the sub-control circuit 72 (S107). The reel stop command includes a parameter for specifying the type of the stopped reel.

  Next, the main CPU 31 determines whether or not there is a stop button whose operation is valid (S108). That is, it is determined whether there is a reel that is still rotating. When the main CPU 31 determines that there is a stop button with an effective operation, the process proceeds to S101, and when it determines that there is no stop button with an effective operation, the main CPU 31 ends the reel stop control process.

[Bonus activation check process]
Next, the bonus operation check process will be described with reference to FIG. First, the main CPU 31 determines whether or not the display combination is BB (S121). When the main CPU 31 determines that the display combination is BB, the main CPU 31 refers to the bonus operation time table (see FIG. 9) and performs BB operation processing (S122). In this process, the BB operating flag is turned on, and a predetermined value is set in the bonus end number counter.

  Next, the main CPU 31 clears the carryover combination storage area (see FIG. 15) (S123). Next, the main CPU 31 transmits a bonus start command to the sub-control circuit 72 (S124). When this process ends, the bonus operation check process ends.

  When determining that the display combination is not BB in S121, the main CPU 31 determines whether or not the display combination is replay (S125). When determining that the display combination is replay, the main CPU 31 copies the value of the insertion number counter to the automatic insertion number counter (S126).

  When determining that the display combination is not replay in S125, the main CPU 31 determines whether or not the BB operating flag is on (S127). When determining that the BB operating flag is not on, the main CPU 31 ends the bonus operation check process, whereas when determining that the BB operating flag is on, whether or not the RB operating flag is on. Is determined (S128).

  When determining that the RB operating flag is on, the main CPU 31 ends the bonus operation check process. On the other hand, when determining that the RB operating flag is not on, the main CPU 31 reads the bonus operating time table (see FIG. 9). Referring to FIG. 5, processing at the time of RB operation is performed (S129). In this process, the RB operating flag is turned on, and predetermined values are set in the winning possible number counter and the possible gaming number counter. When this process ends, the bonus operation check process ends.

[Bonus end check process]
Next, the bonus end check process will be described with reference to FIG. First, the main CPU 31 determines whether or not the bonus end number counter is 0 (S141). When determining that the bonus end number counter is 0, the main CPU 31 performs BB end time processing (S142). In this process, the BB operating flag and the RB operating flag are turned off, and various counters for managing the end timing of the bonus are cleared. Next, the main CPU 31 transmits a bonus end command to the sub-control circuit 72 (S143). When this process ends, the bonus end check process ends.

  When the main CPU 31 determines that the bonus end number counter is not 0 in S141, the main CPU 31 updates the winning possible number counter or the possible gaming number counter (S144). In this process, the possible game number counter is decremented by one, and if there is a win, the possible pay number counter is decremented by one. Next, the main CPU 31 determines whether or not the winning possible number counter or the possible gaming number counter is 0 (S145).

  When the main CPU 31 determines that the winning possible number counter or the possible gaming number counter is not 0, the main CPU 31 ends the bonus end check process, while determining that the possible winning number counter or the possible game number counter is 0, Processing at the end of RB is performed (S146). In this process, the RB operating flag is turned off, and the winning possible number counter and the possible gaming number counter are cleared. When this process ends, the bonus end check process ends.

[Interrupt processing under the control of the main CPU (1.1173 msec)]
Next, an interrupt process (1.1173 msec) controlled by the main CPU 31 will be described with reference to FIG. First, the main CPU 31 saves a register (S161). Next, the main CPU 31 performs input port check processing (S162). In this process, signals input from various switches such as the stop switch 7S are checked.

  Next, the main CPU 31 performs a reel control process (S163). In this process, when the start of rotation of all reels 3L, 3C, 3R is requested, the rotation of the reels 3L, 3C, 3R is started, and then the stepping motors 49L, 49C, The drive of 49R is controlled. When the number of sliding pieces is determined, the driving of the stepping motor is controlled so that the rotation of the corresponding reel waits for the number of sliding pieces and the rotation is decelerated and stopped.

  Next, the main CPU 31 performs a lamp and 7-segment drive process (S164). Next, the main CPU 31 restores the register (S165). When this process ends, the interrupt process ends.

[Program flow executed by sub CPU of sub control circuit]
This completes the description of the contents of the program executed by the main CPU 31 of the main control circuit 71. Next, the contents of a program executed by the sub CPU 81 of the sub control circuit 72 will be described with reference to FIGS.

[Main board communication task]
The main board communication task performed by the sub CPU 81 will be described with reference to FIG. First, the sub CPU 81 performs reception check of the command transmitted from the main control circuit 71 (S301). Next, when receiving a command, the sub CPU 81 extracts the type of the command (S302).

  Next, the sub CPU 81 determines whether or not a command different from the previous one has been received (S303). If the sub CPU 81 determines that a command different from the previous command has not been received, the process proceeds to S301. On the other hand, if the sub CPU 81 determines that a command different from the previous command has been received, the sub CPU 81 stores the command in the message queue (S304).

[Direction registration task]
Next, an effect registration task performed by the sub CPU 81 will be described with reference to FIG. First, the sub CPU 81 extracts a message from the message queue (S311). Next, the sub CPU 81 determines whether there is a message (S312). When the sub CPU 81 determines that there is a message, it copies the game information from the message (S313). For example, various data such as an internal winning combination, a type of reel that has stopped rotating, a display combination, an operating flag, and the like specified by parameters are copied to a storage area provided in the sub-RAM 83.

  Next, the sub CPU 81 performs an effect content determination process which will be described later with reference to FIG. 25 (S314). In this process, depending on the type of the received command, the contents of the effect are determined and the effect data is registered.

  The sub CPU 81 registers animation data after S314 or when it is determined that there is no message in S312 (S315). Next, the sub CPU 81 registers sound data (S316). Next, the sub CPU 81 registers lamp data (S317). The registration of animation data, the registration of sound data, and the registration of lamp data are performed based on the effect data registered in the effect content determination process (see FIG. 28 described later). When this process ends, the process proceeds to S311.

[Production content decision processing]
Next, with reference to FIG. 28, the flowchart of the effect content determination process performed by sub CPU81 is demonstrated. First, the sub CPU 81 determines whether or not it is a start command reception time (S321). When determining that the start command is received, the sub CPU 81 extracts the effect random number, determines the effect number by lottery based on the internal winning combination, and registers it (S322). The production number is data for designating production contents to be executed this time.

  Next, the sub CPU 81 registers the production data at the start based on the registered production number (S323). The effect data is data that designates animation data, sound data, and lamp data. When the effect data is registered, corresponding animation data and the like are determined, and effects such as video display are executed. When this process ends, the effect content determination process ends.

  Next, when determining that the start command is not received, the sub CPU 81 determines whether or not the reel stop command is received (S324). If the sub CPU 81 determines that the reel stop command is received, the sub CPU 81 registers the stop effect data based on the registered effect number and the type of the operation stop button (S325). The operation stop button is a button that is pressed out of the effective stop buttons. When this process ends, the effect content determination process ends.

  Next, when determining that the reel stop command is not received, the sub CPU 81 determines whether or not the display command is received (S326). When determining that the display command is being received, the sub CPU 81 registers the display effect data based on the registered effect number (S327). When this process ends, the effect content determination process ends.

  Next, when determining that the display command is not received, the sub CPU 81 determines whether or not the bonus start command is received (S328). If the sub CPU 81 determines that the bonus start command has been received, the sub CPU 81 registers the bonus start effect data (S329). When this process ends, the effect content determination process ends.

  Next, when determining that the bonus start command is not received, the sub CPU 81 determines whether or not the bonus end command is received (S330). When the sub CPU 81 determines that the bonus end command is not received, the sub CPU 81 ends the effect content determination process. On the other hand, if the sub CPU 81 determines that the bonus end command is received, the sub CPU 81 registers the bonus end effect data (S331). . When this process ends, the effect content determination process ends.

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

  In the above-described embodiment, the first random number value and the second random number value are random numbers generated by one random number generator 36. However, the present invention is not limited to this. For example, each random value may be a random value generated by a different random number generator, the first random value is extracted from the random numbers generated by the first random number generator, and the second random value is It may be extracted from random numbers generated by a second random number generator other than the one random number generator.
