The various information display unit 17 is configured by a throwable display lamp, a replay display lamp, a weight display lamp, a status lamp, a bet number display unit, a stored number display unit, and a prize number display unit.

  The insertable display lamp is turned on when the bet number of the variable game can be set or when a medal as a game medium can be inserted into the slot machine 10. The insertable display lamp is turned off when the variable game is started, or when the maximum bet number (MAXBET) is set and the stored data (credit) reaches the upper limit number of credits. The re-game display lamp is turned on when a re-game is given.

  The wait display lamp is turned on when a start operation is detected before the wait time elapses, and is turned off after the wait time elapses. When a start operation is detected during the wait time, the reels 13L, 13C, and 13R start to rotate after the wait time has elapsed. In addition, after the wait time has elapsed, an enabling condition for enabling the operation of the stop button 23 for deriving the lottery result of the internal lottery is established.

  The status lamp is turned on and off as the changing game progresses. Further, the betting number display section is composed of a plurality of lamps, and the lamps are turned on according to the number of bets in the variable game. The stored number display section displays the number of credits stored and stored inside the machine. The award number display unit displays the number of award medals associated with the symbol combination when a symbol combination for which a medal payout is determined as a prize is stopped on the winning line NL.

  The slot machine 10 is provided with a medal slot 18. The medal inserted from the medal slot 18 passes through a medal selector 19 provided inside. The medal selector 19 is provided with a medal sensor SE4 (shown in FIG. 2) that detects the inserted medal. The medals that have passed through the medal selector 19 are stored in the hopper 26 for storing the inserted medals.

  The hopper 26 has a function of storing medals. The hopper 26 has a function of paying out medals. The medals paid out from the hopper 26 are discharged from a medal discharge port 24 formed at the lower center of the slot machine 10. A tray 25 is provided below the medal outlet 24.

  A settlement switch 21 is provided on the lower left side of the MAXBET button 20. When the settlement switch 21 is operated, medals bet or credits stored and stored at the start of the variable game are paid out.

  Also, a start lever 22 is provided at the right position of the checkout switch 21 as a start operation means that is operated when starting the variable game. In this embodiment, the reels 13L, 13C, and 13R are started to rotate by operating the start lever 22 after the setting of the bet number is completed.

  A stop button 23 as a stop operation means is provided at a right position of the start lever 22. The stop button 23 includes a stop button 23L, a stop button 23C, and a stop button 23R. The stop button 23L is a button for stopping the rotating left reel 13L. The stop button 23C is a button for stopping the rotating middle reel 13C. The stop button 23R is a button for stopping the rotating right reel 13R. Thus, the stop button 23L corresponds to the left reel 13L, the stop button 23C corresponds to the middle reel 13C, and the stop button 23R corresponds to the right reel 13R.

Next, an operation for a player to play a variable game and operation modes of various devices associated with the operation will be described.
In a state where medals can be inserted into the floating game or the MAXBET button 20 can be operated, the bet number can be set by operating the MAXBET button 20. Depending on the operation of the MAXBET button 20, a credit corresponding to the maximum bet number that can be set in the target variable game is set as the bet number from the stored credits.

  In the slot machine 10, the number of bets can be set by inserting medals corresponding to the number of bets from the medal slot 18. At this time, the number of bets for one bet is set by inserting one medal, and the number of bets for three bets is set by inserting three medals. When medals exceeding the maximum number of bets that can be set in the target variable game are inserted from the medal insertion slot 18, they are stored as credits. Incidentally, the medal inserted from the medal insertion port 18 may be discharged (returned) from the medal discharge port 24 without being stored in the hopper 26. When the MAXBET button 20 is operated, the maximum bet number is set.

  When the number of bets is set as described above and the operation of the start lever 22 can be accepted, that is, when the start lever 22 is operated in a state where the game can be started, the reels 13L, 13C, and 13R are rotated and seen through. In the window 16, a plurality of kinds of symbols are displayed so as to fluctuate. Thereafter, when the enabling condition is satisfied after the reels 13L, 13C, and 13R start to rotate, the operation of the stop buttons 23L, 23C, and 23R is accepted. Subsequently, when the stop buttons 23L, 23C, and 23R are operated, the rotation of the reels corresponding to the operated stop buttons is stopped, and the symbols are stopped and displayed on the upper, middle, and lower rows of the corresponding row in the fluoroscopic window 16. Is done.

  When the symbol combination stopped and displayed on the winning line NL when the rotation of all the reels 13L, 13C, and 13R is stopped is a symbol combination for which a prize is determined, the symbol combination is determined. Awards are awarded.

  In the slot machine 10 of the present embodiment, when the symbol combination is stopped and displayed on the winning line NL, the symbols displayed at positions other than the winning line NL are also automatically determined. For this reason, in any case where nine symbols visible from the fluoroscopic window 16 are collectively defined as a display result and when a symbol combination stopped on the winning line NL is defined as a display result, the fluoroscopic window 16 Corresponds to the result display section.

  A one-time variable game is triggered by the start operation by setting the number of bets and the operation of the start lever 22, and by the stop operation including the operation of the stop buttons 23L, 23C, 23R, all the reels 13L, 13C, 13R are started. The process ends when the rotation stops and the symbol combination (display result) is displayed. By the way, if the symbol combination displayed with all reels stopped rotating is a symbol combination with a prize such as award medals or replays, all reels stop rotating and symbol combinations Is displayed, the awarding determined for the symbol combination is completed, and one variation game is completed.

Next, in the slot machine 10 of the present embodiment, a symbol combination that is stopped and displayed on the winning line NL will be described.
In the slot machine 10 of the present embodiment, the symbol combinations for which a prize is determined include a bonus stop, a payout stop, and a re-game stop. Incidentally, in the slot machine 10 of the present embodiment, there are a reach and a miss in the symbol combinations for which no prize is determined. In the following description, the reach eyes and the missed eyes are collectively referred to as “missing stop eyes”.

  When a symbol combination classified as a bonus stop eye is stopped and displayed on the winning line NL, a bonus game is generated (given). The bonus game ends when a bonus game end condition is satisfied. In the present embodiment, the bonus game end condition is satisfied when the number of paid-out medals exceeds a predetermined maximum payout number (for example, 264).

  When the symbol combination classified as the payout stoppage is stopped and displayed on the winning line NL, a predetermined number of medals are awarded as award medals. In the present embodiment, only one type of symbol combination in which medals are paid out (award medal grant) is presented as an award, but a plurality of types of payout combination stoppages with different numbers of medals to be paid out as award medals are determined. May be. For example, when the cherry stop eye and the watermelon stop eye are provided as the payout combination stop eye, when the cherry stop eye is stopped and displayed on the winning line NL, “4” award medals, watermelon stop as the payout stop eye When the eyes are stopped and displayed on the winning line NL, “6” medal medals may be awarded.

  When the symbol combination classified as the replaying role stoppage is stopped and displayed on the winning line NL, replaying is given. When a re-game is awarded, the player can play the next variable game by automatically setting the maximum bet number in the slot machine 10 without betting the bet number. When a re-game is given, a certain profit that the next variable game can be played without consuming the medal is given, while no prize medal is given.

  In the slot machine 10 of the present embodiment, there are general games and bonus games as internal control states. In each internal control state, different winning information lotteries are performed. In the winning information lottery, a determination is made as to whether or not display of a symbol combination for which a prize is determined is permitted.

  Here, winning information (so-called condition device combination) in the slot machine 10 of the present embodiment will be described. The winning information in the slot machine 10 of the present embodiment includes bonus winning information, payout winning information, and re-game winning information.

  The bonus winning information is winning information that can be won in general games. On the other hand, the bonus winning information is winning information that is not won in the bonus game. When the bonus button information is won, when the stop button is operated at a timing at which the bonus stop eye can be stopped (hereinafter referred to as “bonus stop timing”), the bonus stop eye is stopped on the winning line NL. Is displayed. After the next variable game, until the bonus game end condition is satisfied, the variable game is played under the winning information lottery when controlled by the bonus game, and the bonus game is given. On the other hand, when the stop button is operated at a timing at which the bonus stop eye cannot be stopped when the bonus winning information is won (hereinafter referred to as “bonus non-stop timing”), the reach eye is placed on the winning line NL. Will be stopped and no bonus game will be given. Thus, winning of the bonus winning information is equivalent to allowing the display of the bonus stop eye.

  Further, when the bonus stop eye display is permitted, the bonus winning history indicating that the bonus stop eye display is permitted is carried over until the bonus stop eye is stopped and displayed on the winning line NL. The bonus winning history corresponds to control information indicating that a bonus game has been assigned.

  Incidentally, in the slot machine 10 of the present embodiment, in the situation where the bonus winning history is carried over, it is possible to stop and display the bonus stop eye when it is out of place (when no winning information is won). Become. Even in a general game, the bonus winning information is not won if the bonus winning history is carried over.

  The payout winning information is winning information that can be won in any of a general game and a bonus game. When winning the payout combination winning information, when the stop button is operated according to a predetermined operation mode (operation timing, operation order, or any of them), the payout combination stop eye is stopped and displayed on the winning line NL, An award medal is awarded. Winning the payout combination winning information is equivalent to permitting display of the payout combination stoppage.

  In addition, in the case of a bonus game, the probability of winning the payout combination winning information is higher than in the case of a general game. Accordingly, there are more opportunities for award medals to be awarded by the stop display of the payout combination stop when the bonus game is won than when the game is a general game. For this reason, it can be said that a bonus game (a bonus game is given) is an advantageous state (advantageous state) for the player. In the present embodiment, when winning the bonus winning information in the winning information lottery is regarded as an advantageous lottery result, not winning the bonus winning information corresponds to a lottery result that is less advantageous than the advantageous lottery result.

  The re-game role winning information is winning information that can be won only in general games. In this embodiment, winning information that can be won only in general games is used, but winning information that can be won in bonus games may also be used. When the re-game player winning information is won, when the stop button is operated according to a predetermined operation mode (operation timing, operation sequence, or any of them), the re-game player stop eye is stopped and displayed on the winning line NL. And replays are awarded. Winning the re-gamer winning information is equivalent to allowing display of the re-gamer stoppage.

  As described above, in the slot machine 10 of the present embodiment, by winning the winning information, it is allowed to display any one of the bonus stop eye, the payout stop time, and the re-game hand stop time.

Next, as shown in FIG. 2, the electrical configuration of the slot machine 10 will be described.
The slot machine 10 is equipped with a main control board 40 as a main control unit. Further, the main control board 40 executes various processes, calculates various control signals (control commands) according to the processing results, and outputs the control signals. Further, the slot machine 10 is equipped with a sub control board 41 as a sub control unit that executes effect control according to the gaming state. The sub control board 41 receives various control signals output from the main control board 40 and executes predetermined control based on the control signals.

Hereinafter, the main control board 40 will be described.
The main control board 40 has a main control CPU 40a that executes control operations in a predetermined order, a main control ROM 40b that stores a control program for the main control CPU 40a, and a main control board that can write and read necessary data. A RAM 40c is provided. The main control ROM 40b is a read-only memory.

  The main control board 40 is provided with a random number generator 40d that generates hardware random numbers. In the random number generator 40d, the value of the hardware random number is updated at a specific cycle. In the random number generator 40d, the value of the hardware random number is updated by 1 for each specific period until the upper limit is reached. Then, in the random number generator 40d, when the updated hardware random number value reaches the upper limit value, the hardware random number value is updated again from the initial value. In the present embodiment, the hardware random number generated by the random number generator 40d corresponds to non-specific numerical information, and the random number generator 40d for updating the value of the hardware random number at a specific cycle includes non-specific numerical information updating means. Function as. Note that the value of the hardware random number (first random number) generated by the random number generator 40d is updated between “0000000000000000000B” and “1111111111111111B”.

  The main control CPU 40a is connected to reels 13L, 13C, 13R, reel sensors SE1, SE2, SE3, medal sensor SE4, and hopper 26 constituting the drum unit 13. Various information display units 17 are connected to the main control CPU 40a. The main control CPU 40a is connected with a MAXBET button 20, a settlement switch 21, a start lever 22, and stop buttons 23L, 23C, and 23R.

  A first position signal is input from the reel sensor SE1 to the main control CPU 40a according to the rotation position of the rotating left reel 13L. A second position signal is input from the reel sensor SE2 to the main control CPU 40a in accordance with the rotation position of the middle reel 13C that is rotating. Similarly, a third position signal is input to the main control CPU 40a from the reel sensor SE3 according to the rotation position of the rotating right reel 13R. Then, the main control CPU 40a controls the rotation and stop of the reels 13L, 13C, 13R based on the first to third position signals.

  Each time the medal sensor SE4 detects a medal, a medal detection signal indicating that a medal has been detected is input to the main control CPU 40a. Further, when the MAXBET button 20 is operated, a control signal indicating that the MAXBET button 20 is operated is input to the main control CPU 40a. Further, when the settlement switch 21 is operated, a control signal indicating that the settlement switch 21 has been operated is input to the main control CPU 40a.

  When the start lever 22 is operated, a control signal indicating that the start lever 22 has been operated is input to the main control CPU 40a. Further, when any of the stop buttons 23L, 23C, and 23R is operated, a control signal indicating that the operation is performed from the operated stop button is input to the main control CPU 40a.

  A main control program is stored in the main control ROM 40b. The main control ROM 40b stores a winning information table in which a winning probability for each winning information is determined. In the slot machine 10, the winning information table is stored in the main control ROM 40b for each internal control state. The winning information table is used in winning information lottery (so-called role lottery).

  In the winning information lottery, the type of winning or winning information is determined. That is, since the type of the winning information is determined by the winning information lottery, this corresponds to determining whether or not display of the symbol combination in which the prize is determined is permitted by the winning information lottery. Furthermore, in the winning information lottery, this corresponds to determining the type of display result that is allowed to be displayed.

The main control CPU 40a controls the internal control state. Depending on the type of internal control state, the main control CPU 40a performs various processes (for example, winning information lottery).
In the main control RAM 40c, a software random number is generated. The main control CPU 40a updates the software random number generated by the main control RAM 40c at a predetermined cycle. Unlike the hardware random number generated by the random number generator 40d, the software random number is not necessarily updated by one every predetermined period. The update of software random numbers will be described in detail later. In the present embodiment, the software random number generated in the main control RAM 40c corresponds to the specific numerical information, and the main control CPU 40a that updates the value of the software random number at a predetermined cycle functions as the specific numerical information update means. To do. Incidentally, the value of the software random number (second random number) generated in the main control RAM 40c is updated between “000000000000000000B” to “1111111111111111B”. Therefore, the lower limit value of the second random number is “0000000000000000000B”, and the upper limit value of the second random number is “1111111111111111B”.

  Incidentally, in the slot machine 10 of the present embodiment, the software random number generated by the main control RAM 40c is the period in which the value of the hardware random number generated by the random number generator 40d is updated (specific period). Is shorter than the period (predetermined period) in which the value of is updated. However, the period in which the value of the hardware random number is updated may be the same as or longer than the period in which the value of the software random number is updated.

  In the following description, the hardware random number updated by the random number generator 40d is referred to as “first random number”, and the software random number updated in the main control RAM 40c is referred to as “second random number”.

Next, the sub control board 41 will be described.
The sub-control board 41 includes a sub-control CPU 41a that executes control operations in a predetermined procedure, a sub-control ROM 41b that stores a control program for the sub-control CPU 41a, and a sub-control RAM 41c that can write and read necessary data. Is provided. The sub control ROM 41b is a read only memory.

  The effect display device 14 is connected to the sub-control CPU 41a. Further, a decoration lamp LA is connected to the sub control CPU 41a. A speaker SP is connected to the sub control CPU 41a.

  A sub control program is stored in the sub control ROM 41b. The sub-control ROM 41b also displays a display effect pattern indicating the display effect mode of the effect display device 14, a sound effect pattern indicating the sound output mode of the speaker SP, and a light emission effect pattern indicating the light emission mode of the decoration lamp LA. Is remembered.

  The sub-control RAM 41c stores (sets) various information that can be appropriately rewritten during the operation of the slot machine 10. Specifically, the sub-control CPU 41a stores sub-control state information (flags, etc.) concerning the internal control state in the sub-control RAM 41c.

Hereinafter, the process (game progress main process) related to the variable game executed by the main control CPU 40a based on the main control program will be described.
As shown in FIG. 3, in the game progress main process, the main control CPU 40a starts accepting bets for medals (step S11). Next, the main control CPU 40a determines whether or not it is a re-game operation (step S12). In the determination process in step S12, it is determined whether or not the symbol combination in which replay is determined as a prize in the immediately preceding symbol variation game, that is, whether or not the re-gamer stop eye has been won (stopped display on the winning line NL). This corresponds to the determination process for. If the determination result of step S12 is affirmative, the main control CPU 40a sets the maximum bet number to the bet number stored in the main control RAM 40c, and then proceeds to the process of step S14.

  If the determination result in step S12 is negative, medal management is performed (step S13). In step S13, the main control CPU 40a sets the number of bets stored in the main control RAM 40c based on the input of the medal detection signal from the medal sensor SE4 and the input of the control signal from the MAXBET button 20. Accordingly, in step S13, when the medal detection signal from the medal sensor SE4 is input, the main control CPU 40a adds 1 to the bet number stored in the main control RAM 40c. In step S13, when the control signal from the MAXBET button 20 is input, the main control CPU 40a adds a value to the bet number so that the bet number stored in the main control RAM 40c becomes the maximum bet number. The credit is subtracted by the added amount.

  Further, when the determination result of step S12 is affirmative and when the process of step S13 is terminated, the main control CPU 40a determines whether or not the bet number matches the maximum bet number (step S14). In step S14, the main control CPU 40a determines whether or not it is in a state in which a variable game can be started. As described above, in the slot machine 10 according to the present embodiment, the variable game start enabling condition for enabling the start of the variable game is established by betting the maximum number of bets. If the determination result of step S14 is negative, the main control CPU 40a proceeds to the process of step S12.

  When the determination result of step S14 is affirmative, the main control CPU 40a determines whether or not a start operation has been accepted (step S15). In step S15, the main control CPU 40a determines whether or not a control signal from the start lever 22 has been input. If the determination result of step S15 is negative, the main control CPU 40a proceeds to the process of step S12.

  On the other hand, if the determination result of step S15 is affirmative, the main control CPU 40a performs an internal lottery process (step S16). In step S16, the main control CPU 40a performs a winning information lottery. The specific control contents of the internal lottery process will be described later.

  Further, after performing the internal lottery process, the main control CPU 40a determines whether or not the wait time has elapsed (step S17). When the determination result of step S17 is negative, the main control CPU 40a waits until the wait time elapses, that is, until the determination result of step S17 becomes affirmative.

  When the wait time has elapsed, the main control CPU 40a sets the wait time (step S18). In step S18, the main control CPU 40a sets the wait time to be determined in step S17 when the next variable game is performed.

  Thereafter, the main control CPU 40a outputs a control signal to the stepping motors corresponding to the reels 13L, 13C, and 13R to start rotation of the reels 13L, 13C, and 13R (step S19). After starting the rotation of each reel 13L, 13C, 13R, the main control CPU 40a determines whether or not the rotation speeds of all the reels have reached a constant speed (step S20). If the determination result in step S20 is negative, the main control CPU 40a waits until all reels rotate at a constant speed, that is, until the determination result in step S20 becomes affirmative.

  Then, after the rotation speeds of all the reels reach a constant speed, the main control CPU 40a determines whether or not a stop operation has been accepted (step S21). In step S21, the main control CPU 40a determines whether or not an operation signal is input from the stop button corresponding to the rotating reel. When the determination result of step S21 is negative, the main control CPU 40a proceeds to the process of step S23.

  On the other hand, if the determination result of step S21 is affirmative, the main control CPU 40a performs a rotation stop process and performs a rotation stop process for stopping the rotation of the reel corresponding to the operated stop button (step S22). .

  In step S22, the main control CPU 40a stops the rotation of the reel corresponding to the operated stop button within a predetermined range (maximum of 4 symbols) from the timing when the stop button is operated. In step S22, the main control CPU 40a controls the stop control stored in the main control ROM 40b according to the lottery result of the winning information lottery, the operation order of the stop button 23, the operation timing of the stop button 23, and the like. The rotation of the reel is stopped based on the data.

  When the determination result of step S21 is negative and when the process of step S22 is terminated, the main control CPU 40a determines whether or not all reels are stopped (step S23). When the determination result of step S23 is negative, the main control CPU 40a proceeds to the process of step S21.

  On the other hand, if the determination result of step S23 is affirmative, the main control CPU 40a performs display result determination (step S24). In step S24, the main control CPU 40a determines whether or not the symbol combination stopped and displayed on the winning line NL is a symbol combination for which a prize is determined, and if the symbol combination is for which a prize is determined. Judge the winning symbol combination. Specifically, the main control CPU 40a determines whether or not the symbol combination corresponding to the lottery result of the winning information lottery in the internal lottery process is actually stopped and displayed on the winning line NL. The type of the symbol combination is determined. In step S24, when the symbol combination for which replay is determined is stopped and displayed on the winning line NL, the main control CPU 40a activates replay. Thereby, replay as a prize is given.

  Following the process of step S24, the main control CPU 40a determines whether or not to pay out medals (step S25). In step S25, the main control CPU 40a determines whether or not a symbol combination for which a medal payout is determined as a prize has been won. If the determination result of step S25 is negative, the main control CPU 40a proceeds to the process of step S27.

  On the other hand, if the determination result in step S25 is affirmative, the main control CPU 40a pays out the number of medals determined for the winning symbol combination (step S26) and gives a prize medal. In step S26, the main control CPU 40a adds the number of medals to be paid out to the credit. Incidentally, when the credit upper limit number is exceeded when added to the credit, the main control CPU 40a drives the hopper 26 so as to pay out medals for the amount exceeding the credit upper limit number.

  When the determination result of step S25 is negative and when the process of step S26 is completed, the main control CPU 40a ends the variable game (step S27). In step S27, the main control CPU 40a performs control to shift the internal control state, or outputs to the sub control CPU 41a a winning instruction command indicating that the symbol combination for which a prize has been determined is stopped and displayed on the winning line NL. I do. Thereafter, the main control CPU 40a ends the game progress main process related to the execution of one variable game, and proceeds to the process of step S11 again.

Here, based on FIG. 4, the internal lottery process (step S16) performed in the game progress main process will be described.
In the internal lottery process, the main control CPU 40a acquires the value of the first random number (step S31). In step S31, the main control CPU 40a acquires the value of the first random number (hardware random number) updated by the random number generator 40d. Subsequently, the main control CPU 40a acquires the value of the second random number (step S32). In step S32, the main control CPU 40a acquires the value of the second random number (software random number) updated in the main control RAM 40c.

  Thereafter, the main control CPU 40a generates a lottery random number used in the winning information lottery (step S33). In step S33, the main control CPU 40a generates a lottery random number value based on the sum of the first random number value and the second random number value (first random number + second random number).

  Then, the main control CPU 40a refers to the winning information table stored in the main control ROM 40b based on the value of the random number for lottery and performs the winning information lottery (step S34). In the present embodiment, the main control CPU 40a that performs the winning information lottery (lottery) functions as a lottery means.

  Subsequently, when the winning information lottery wins any of the winning information, the main control CPU 40a stores winning information data that can identify the winning information that has been won (step S35), and ends the internal lottery process. Incidentally, the main control CPU 40a ends the internal lottery process without storing the winning information data when no winning information is won in the winning information lottery, that is, when the winning information is lost.

Next, a description will be given of processing related to a variable game executed by the sub control CPU 41a based on the sub control program.
When the sub-control CPU 41a inputs various commands, the display contents of the effect display device 14, the sound output mode of the speaker SP, and the light-emission mode of the decoration lamp LA so as to execute various effects based on the contents instructed by the command. To control.

  Here, in this embodiment, the update of the value of the second random number corresponding to the specific numerical information will be described. The value of the second random number updated in the main control RAM 40c is updated when the main control CPU 40a performs the second random number update process. When the main control CPU 40a performs the second random number update process at predetermined intervals, the value of the second random number is updated at predetermined intervals.

Hereinafter, the second random number update process will be described with reference to FIG.
In the second random number update process, the main control CPU 40a stores the chip individual number rotation data stored in the main control RAM 40c in the HL register (step S41). Incidentally, the value stored in the HL register as the chip individual number rotation data in the processing of the first step S41 after the power is turned on to the slot machine 10 is “0 (zero)”.

  Subsequently, the main control CPU 40a adds 1 to the HL register (step S42). Further, the main control CPU 40a updates the chip individual number rotation data (step S43). In step S43, the main control CPU 40a stores the value of the HL register in the main control RAM 40c as chip individual number rotation data.

  Thereafter, the main control CPU 40a stores the value of the HL register in the A register (step S44). Then, the main control CPU 40a stores the logical product of the value of the A register and the first specified value “00000111B” in the A register (step S45).

  After the process of step S45, the main control CPU 40a adds 1 to the A register (step S46), and stores the value of the A register in the B register (step S47). Note that the value stored in the B register in step S47 is the number of rotations. The value stored in the B register in step S47 is a value derived based on the values updated by the processing in steps S41 to S43. For this reason, the number of rotations can be changed.

  After the processing in step S47, the main control CPU 40a stores the chip individual number register address in the HL register (step S48). Here, the chip individual number register address will be described.

  The main control ROM 40b provided in the slot machine 10 is assigned a chip individual number register address for each slot machine. The chip individual number register address is composed of four individual numbers from a first individual number to a fourth individual number. The chip individual number register address assigned to the main control ROM 40b is unique information and is different for each slot machine (main control ROM). In the present embodiment, the chip individual number register address corresponds to identification information, and the first to fourth individual numbers correspond to information constituting the identification information. The main control ROM 40b to which the chip individual number register address is assigned functions as a unique identification unit.

  FIG. 6 illustrates chip individual number register addresses assigned to the first ROM, the second ROM, the third ROM, and the twentieth ROM. The first ROM, the second ROM, the third ROM, and the twentieth ROM are installed in different slot machines.

  For example, in the slot machine equipped with the main control ROM corresponding to the first ROM, in the process of step S48, the first individual number “01H”, the second individual number “07H”, the third A chip individual number register address composed of the individual number “BBH” and the fourth individual number “06H” is stored in the HL register. On the other hand, in the slot machine equipped with the main control ROM corresponding to the twentieth ROM, the first individual number “0BH”, the second individual number “05H”, and the third individual number in the process of step S48. A chip individual number register address composed of “01H” and the fourth individual number “04H” is stored in the HL register.

  Since the chip individual number register address is stored in the main control ROM 40b which is a read-only memory, the chip individual number register address of the main control ROM 40b in which the chip individual number register address is already stored cannot be rewritten. . If the chip individual number register address is changed, the ROM itself must be changed, and the chip individual number register address cannot be changed without touching the equipped main control ROM 40b.

  As shown in FIG. 5, the main control CPU 40a that has finished the process of step S48 stores the value of the R register in the A register (step S49). The value of the R register is updated every time processing control is performed. Further, the value of the R register is different depending on the type of processing control (update mode). For example, if the main control CPU 40a performs the first process control (for example, read process), the value of the R register is updated in the first update mode (1 addition), and the main control CPU 40a performs the second process control (for example, the read process). , Determination processing), the value of the R register is updated in the second update mode (addition of 2). As described above, it is difficult to estimate the value being updated as compared with the value (numerical information) in which the value of the R register is simply updated at a predetermined interval, for example, 1 is added every predetermined period. . Note that the value of the R register is updated between “00000000B” and “01111111B”.

  After that, the main control CPU 40a that has finished the process of step S49 stores the logical product of the value of the A register and the second specified value “00000011B” in the A register (step S50).

  Then, the main control CPU 40a specifies an individual number used for calculation (step S51). In step S51, the main control CPU 40a specifies the individual number used for the calculation from the chip individual number register address based on the value of the A register (the calculation result of step S50). Incidentally, the value that the calculation result of step S50 can take is “0 to 3”. In step S51, the main control CPU 40a is “0” if the first individual number, and if it is “1”, the second individual number. If it is “2”, the third individual number is specified, and if it is “3”, the fourth individual number is specified.

  Subsequently, the main control CPU 40a rotates the specified individual number (step S52), and stores the value after rotation in the A register. In step S52, the main control CPU 40a rotates the individual number converted into a binary number. For example, when the second individual number “02H” of the second ROM is specified in step S51, “00000010B” converted to binary number is rotated to “00000001B”. As described above, the individual number to be rotated in step S52 of the present embodiment corresponds to the reference numerical value information. In the following description, the individual number to be rotated may be referred to as reference numerical value information. Note that the individual number to be rotated in step S52 of this embodiment corresponds to information constituting a chip individual number register address as identification information.

  Thereafter, the main control CPU 40a subtracts 1 from the B register (step S53), and determines whether or not the value of the B register after the subtraction is “0 (zero)” (step S54). Until the determination result in step S54 becomes affirmative, the main control CPU 40a repeats the processes in steps S52 to S54. That is, the main control CPU 40a rotates the reference numerical information (the individual number specified in step S51) over the number of rotations.

  If the determination result in step S54 is affirmative, the main control CPU 40a stores the logical product of the value of the A register and the third specified value “00000011B” in the A register (step S55). Incidentally, information after rotating the reference numerical information for the number of rotations, that is, a value (result) obtained by rotating the individual number for the number of rotations when the determination result in step S54 is affirmative corresponds to the rotation information. To do.

  When the process of step S55 is completed, the main control CPU 40a adds 1 to the A register (step S56). Subsequently, the main control CPU 40a stores the value of the A register in the B register (step S57). Note that the value stored in the B register in step S57 is the number of operations. The number of operations is derived based on rotation information obtained by rotating the reference numerical information over the number of rotations. For this reason, the number of operations is derived based on the chip individual number register address corresponding to the unique identification information.

  Further, as described above, since the number of rotations can be changed or the reference numerical value information can be changed, the rotation information can also be changed. Since the rotation information can be changed, the number of calculations can also be changed. Incidentally, if there is a possibility that at least one of the number of rotations and the reference numerical value information is changed, the number of calculations can also be changed.

  Thereafter, the main control CPU 40a stores a predetermined value (predetermined numerical information) in the DE register (step S58). In step S58, the main control CPU 40a stores “0010011101101011B” as a predetermined value in the DE register. In step S58, the prime number is stored in the DE register. In the present embodiment, the value stored in the DE register in step S58 is the predetermined numerical information.

  Subsequently, the main control CPU 40a stores the value of the second random number before the update in the HL register (step S59). In step S59, the main control CPU 40a stores the second random number stored in the main control RAM 40c in the HL register. In the present embodiment, the value stored in the HL register in step S59 (the value of the second random number updated in the previous second random number update process) is the basic numerical value information.

  Then, the main control CPU 40a stores the logical sum of the HL register and the DE register (the operation result of the HL register + DE register) in the HL register (step S60). In step S60, the main control CPU 40a calculates basic numerical information and predetermined numerical information. In this embodiment, the addition method is employed as the calculation method, but a subtraction method, a multiplication method, a division method, or the like may be employed.

  Thereafter, the main control CPU 40a subtracts 1 from the B register (step S61), and determines whether or not the value of the B register after the subtraction is “0 (zero)” (step S62). Until the determination result of step S62 becomes affirmative, the main control CPU 40a repeats the processing of step S60 to step S62. For this reason, the main control CPU 40a calculates the basic numerical information and the predetermined numerical information over the number of calculations. Incidentally, when the calculation result exceeds the upper limit value of the second random number, the value obtained by counting only the value exceeding the upper limit value of the second random number from the lower limit value of the second random number is the calculation result. For example, when the upper limit value “1111111111111111B” of the second random number is exceeded by adding 1 to the upper limit value, the operation result becomes the lower limit value “0000000000000B” of the second random number.

  If the determination result in step S62 is affirmative, the main control CPU 40a stores the value of the HL register in the main control RAM 40c (step S63), and ends the second random number update process. In step S63, the main control CPU 40a stores the value of the HL register as the “second random number value” in the main control RAM 40c, and updates the second random number value. As described above, in the present embodiment, the main control CPU 40a that performs the second random number update process at predetermined intervals functions as specific numerical information update means that updates the value of the second random number corresponding to the specific numerical information. .

  As described above, the value of the second random number in the present embodiment is not updated by adding a predetermined value for each predetermined period, but the rotated information (reference numerical information) is not updated. It is updated over the number of calculations derived based on the update.

  Incidentally, the value stored in the B register in step S47 is the number of rotations, but the reference numerical information (individual number) to be rotated is 8 digits when expressed in binary. The result of rotating information represented by an 8-digit binary number (1-byte information) by a number exceeding 8 can be obtained by rotating the number of times by 8 or less. Therefore, the maximum number of effective rotations is “8”.

  In the present embodiment, the first specified value is “00000111B”. Thus, the value stored in the A register after the arithmetic processing in step S45 is “0 to 7” in decimal. Since the value stored in the A register is incremented by 1 in the subsequent step S46, as a result, the value stored in the B register in the step S47 is expressed as “1-8” in decimal. Thus, “8” is the upper limit.

  In other words, by setting the first specified value to “00000111B”, it is possible to calculate so as to obtain a value up to the maximum number of times “8” that is effective as the number of rotations, and to rotate the number of times exceeding 8 in vain. Can be prevented. That is, by restricting the number of rotations exceeding the maximum number of times “8” that is effective as the number of rotations by the first specified value from being determined as the number of rotations, useless control can be suppressed and an increase in control burden can be suppressed.

Hereinafter, the update of the second random number will be described.
It is assumed that the chip individual number rotation data stored in the main control RAM 40c in step S41 is “10010011B”, and the value of the R register in step S49 is “01010101B”. Further, the main control ROM 40b equipped in the slot machine 10 is assumed to be a third ROM. It is assumed that the value of the second random number before update is “1111111100000000B”.

  When “10010011B” is stored in the HL register as the chip individual number rotation data in step S41, 1 is added in the process in step S42, and in the next second random number update process in step S41, the chip individual number rotation is performed. “10010100B” is stored as data in the main control RAM 40c in step S43.

  Thereafter, “00000100B” that is the logical product of the value “10010100B” of the A register and the first specified value “00000111B” is stored in the A register in step S45. Thereafter, 1 is added in step S46, whereby the value of the A register becomes “00000101B”, and the value is stored in the B register in step S47. As a result, the number of rotations is “00000101B”. Expressed in decimal, the number of rotations is “5”.

  In step S48, the chip individual number register address of the third ROM is stored in the HL register. Subsequently, “01010101B” as the value of the R register is stored in the A register in step S49.

  Thereafter, “00000001B” that is the logical product of the value “01010101B” of the A register and the second specified value “00000011B” is stored in the A register in step S50. As a result, the second individual number “0AH (00001010B)” among the first individual number to the fourth individual number constituting the chip individual number register address assigned to the third ROM is determined in step S51. The individual number used for the calculation, that is, the reference numerical information is used.

  Subsequently, the processing from step S52 to step S54 is performed over the number of rotations. Specifically, “00001010B” serving as reference numerical value information is rotated over the number of rotations “00000101B”. As a result, the rotation information is “00101000B”.

  After that, in step S55, “00000000B” that is the logical product of the rotation information “00101000B” and the third specified value “00000011B” is stored in the A register in step S55. After that, by adding 1 in step S56, the value of the A register becomes “00000001B”, and the value is stored in the B register in step S57. As a result, the number of calculations is “00000001B”. Expressed in decimal, the number of calculations is “1”.

  In step S58, the predetermined value “0010011101101011B” is stored in the DE register, and in step S59, “1111111100000000B” is stored in the HL register as the second random number value (basic numerical information) before update.

Subsequently, the processing from step S60 to step S62 is performed over the number of computations. Specifically, an operation of adding “0010011101101011B” that is a predetermined value to “11111111100000000B” that is basic numerical value information is performed over the number of times “00000001B”, and the value of the second random number is updated. In step S63, the value of the second random number stored in the main control RAM 40c is updated to “0010011001101010B”. Note that in the calculation of the basic numerical value information and the predetermined value exemplified above, the value exceeding the upper limit value of the second random number “1111111111111111B”, the value exceeding the upper limit value of the second random number from the lower limit value “0000000000000B” of the second random number. The value “0010011001101010B” counted only for the second random number is the updated value.
As described above in detail, the present embodiment has the following effects.

  (1) The second random number value (basic numerical information) and the predetermined value (predetermined numerical information) updated in the previous second random number updating process are calculated over the number of times of calculation, and the second as specific numerical information The random value is updated. Furthermore, since the number of calculations performed when updating the value of the second random number can be changed, updating of the value of the second random number can be made more complicated. For this reason, it can suppress that the value of the 2nd random number is acquired illegally, and a lottery result (for example, winning of bonus winning information) advantageous in winning information lottery (lottery) will be derived. Can be suppressed.

  (2) Since the number of calculations is derived based on the rotation information obtained by rotating the reference numerical information (chip individual number used for calculation) over the number of rotations, the number of rotations or the reference value is simply calculated in a “predetermined order”. It is possible to make it difficult to specify the number of calculations compared to the case where information is changed. As a result, it is possible to make it difficult to specify how the value of the second random number as the specific numerical information is updated, and it is possible to suppress the illegal acquisition of the value of the second random number, It can be suppressed that an advantageous lottery result (for example, winning of bonus winning information) is derived in the winning information lottery (lottery).

  (3) The winning information lottery (lottery) is performed based on the value (information) obtained by adding the value of the hardware random number as the non-specific numerical information to the value of the second random number as the specific numerical information. For this reason, it can suppress that an advantageous lottery result (for example, winning of bonus winning information) is illegally derived compared with the case where the winning information lottery is performed based only on the value of the second random number.

  (4) The value of the second random number as the specific numerical information is updated based on the chip individual number register address (unique identification information) assigned to the main control ROM 40b as the unique identification means. Since the chip individual number register address is unique information assigned to the equipped main control ROM 40b, the chip individual number register address is specified on the basis of which the second random number value is updated. It becomes difficult. For this reason, it can suppress that the value of the 2nd random number is acquired illegally, and a lottery result (for example, winning of bonus winning information) advantageous in winning information lottery (lottery) will be derived. Can be suppressed.

  In addition, even if one gaming machine may lead to a fraudulently advantageous lottery result, it is the same for other gaming machines (game machines to which different chip individual number register addresses are assigned). It can be suppressed that a lottery result that is illegally advantageous is derived by the method, and illegal diffusion can also be suppressed.

  (5) Since the chip individual number register address (identification information) is assigned to the ROM as a read-only memory instead of the RAM, it is difficult to perform fraud such as rewriting the chip individual number register address, and the lottery results that are advantageous to the fraud Can be prevented from being derived.

  (6) Rotate the individual number (part of the information constituting the unique identification information) constituting the chip individual number register address, and update the value of the second random number as specific numerical information based on the rotated information after rotation To do. Thus, by rotating and processing even the chip individual number register address, it is more advantageous than the case where the value of the second random number is updated using the chip individual number register or the individual number constituting the chip as it is. It is possible to prevent the lottery result from being illegally derived.

(Second Embodiment)
Next, a second embodiment of the gaming machine will be described with reference to FIGS. In addition, the same code | symbol as 1st Embodiment is attached | subjected to the structure similar to 1st Embodiment, and the detailed description and drawing are abbreviate | omitted.

In the second embodiment, unlike the first embodiment in which the first random number and the second random number are used in the slot machine 10, the first random number and the second random number are used in the pachinko gaming machine 100.
A pachinko gaming machine 100 as a gaming machine shown in FIG. 7 is equipped with a launch handle HD. By rotating the launch handle HD, the strength with which the game ball is launched onto the game board YB can be adjusted.

  The game board YB is provided with a decorative symbol display device 111 as display means for performing a display effect. As the decorative symbol display device 111, for example, a liquid crystal display type display device, a dot matrix type display device, a 7 segment type display device, or the like is used.

  In the decorative symbol display device 111, a decorative symbol variation game that is executed by variably displaying decorative symbols in a plurality of columns (three columns in the present embodiment) is executed. In addition, in the decorative symbol display device 111, various display effects are executed in association with the decorative symbol variation game. In each column, eight types of numbers [1] to [8] are displayed as decorative designs. Each symbol row is composed of eight types of decorative symbols. The decorative symbol variation game is executed when a game ball enters the start opening 115.

  In the decorative symbol variation game, a symbol combination of decorative symbols displayed as a decorative symbol in each column is derived. When winning the big hit lottery, the big symbol combination (for example, [777]) is stopped and displayed on the decorative symbol display device 111. Further, when winning the small hitting lottery, the small symbol combination (for example, [123]) is stopped and displayed on the decorative symbol display device 111. Further, when the big win lottery and the small win lottery are not won, the decorative symbol display device 111 is stopped and displayed with a symbol combination (eg, [426] or [323]).

  Further, a special symbol display device 112 in which a plurality of light emitting members such as LEDs are arranged is arranged on the lower right side of the game board YB. In the special symbol display device 112, a special symbol variation game is executed using a special symbol based on a combination of lighting or extinguishing of the light emitting members constituting the special symbol display device 112. When the execution of the special symbol variation game is started on the special symbol display device 112, the ornament symbol variation game is started on the ornament symbol display device 111, and when the special symbol variation game is ended, the ornament symbol variation game is ended. In the special symbol display device 112, when the big hit lottery is won, the big hit symbol is stopped and displayed. Further, the special symbol display device 112 stops and displays the small hit symbol when winning the small hit lottery. In addition, the special symbol display device 112 stops and displays the lost symbols when the big hit lottery and the small hit lottery are not won. In the pachinko gaming machine 100 of the second embodiment, the special symbol display device 112 is connected to the main control CPU 40a, while the decorative symbol display device 111 is connected to the sub control CPU 41a.

  Incidentally, as the special symbol display device 112, a 7 segment type display device constituted by a plurality of light emitting members or a liquid crystal display type display device may be used. In the following description, the term “symbol variation game” means both a special symbol variation game and a decorative symbol variation game.

  A starting port 115 as a starting ball entering means is disposed below the decorative symbol display device 111. The start opening 115 has a entrance for allowing game balls to enter. In addition, a start sensor that detects that a game ball has entered the start port 115 is disposed on a path through which the game ball that has entered the start port 115 flows. A game ball enters the start port 115, and the game ball is detected by the start sensor, whereby the start condition of the symbol variation game is satisfied. The start sensor is connected to the main control CPU 40a in the pachinko gaming machine 100 of the second embodiment.

  Further, the game board YB is provided with a special winning opening 118 as a special winning means having a special winning door 117. A count sensor that detects that a game ball has entered the big prize opening 118 is disposed on the passage through which the game ball that has entered the big prize opening 118 flows. A game ball enters the big prize opening 118, and when the game ball is detected by a count sensor, a predetermined number of game balls are paid out as a prize ball. The count sensor is connected to the main control CPU 40a in the pachinko gaming machine 100 of the second embodiment.

  Further, the big prize door 117 of the big prize opening 118 is configured to be displaceable between an open state and a closed state by operation of an actuator (for example, a solenoid). When the grand prize winning door 117 is in the open state, the grand prize winning opening 118 is opened, and the game balls are allowed to enter the special winning prize opening 118. On the other hand, when the grand prize winning door 117 is closed, the grand prize winning opening 118 is in a closed state, and entry of game balls into the big winning prize opening 118 is not allowed. The actuator that displaces the special winning door 117 is connected to the main control CPU 40a in the pachinko gaming machine 100 of the second embodiment.

  Further, the pachinko gaming machine 100 is provided with a decorative lamp LA as a light emitting means for performing a light emitting effect. Further, the pachinko gaming machine 100 is provided with a speaker SP as sound output means for performing sound effects.

  In the pachinko gaming machine 100, when the big hit lottery included in the win lottery is won, the big hit game included in the win game is generated. In addition, in the pachinko gaming machine 100, when a small hit lottery included in the win lottery is won, a small hit game included in the win game is generated. When the big hit game and the small hit game are compared, the big hit game has a longer period (time) in which the big prize opening 118 is open than the small hit game, and the hit game is advantageous to the player.

  In addition, a hold display device 120 in which a plurality of light emitting members such as LEDs are arranged is disposed on the lower right side of the game board YB. The pachinko gaming machine 100 is configured so that execution of a special symbol variation game can be suspended. In the hold display device 120, the number of special symbol variation games that are put on hold (hereinafter referred to as “the number of hold storages”) is indicated by turning on, blinking, or turning off the light-emitting members constituting the hold display device 120.

  Note that holding the special symbol variation game is equivalent to holding the big hit lottery or the small hit lottery that is triggered by entering the start opening 115. The reserved special symbol variation game corresponds to a symbol variation game in which the start condition is satisfied but the execution start condition is not satisfied.

  In addition, a plurality of types of variation patterns are stored in the main control ROM 40b of the present embodiment. The variation pattern can specify the variation time (game time) from the start to the end of the symbol variation game. Further, the variation pattern can specify the effect contents (game contents of the variation game) during execution of the symbol variation game.

  In addition, various determination values are stored in the main control ROM 40b. For example, the big hit determination value is stored in the main control ROM 40b. The big hit determination value is a determination value used in the big hit lottery. The main control ROM 40b stores a small hit determination value. The small hit determination value is a determination value used in the small hit lottery.

Next, various processes executed by the main control CPU 40a based on the control program will be described. The main control CPU 40a executes various processes for each predetermined control cycle.
First, the special symbol input process will be described.

  As shown in FIG. 8, the main control CPU 40a determines whether or not a game ball has entered the start port 115 (step S71). In step S71, the main control CPU 40a determines whether or not a detection signal from the start sensor has been input. If the determination result in step S71 is negative, the main control CPU 40a ends the special symbol input process.

  If the determination result of step S71 is affirmative, the main control CPU 40a determines whether or not the reserved storage number is less than the upper limit number (step S72). When the determination result of step S72 is negative, the main control CPU 40a ends the special symbol input process. On the other hand, if the determination result of step S72 is affirmative, the main control CPU 40a proceeds to the process of step S73.

  In step S73, the main control CPU 40a acquires the value of the first random number. In step S73, the main control CPU 40a acquires the value of the first random number updated by the random number generator 40d. Subsequently, the main control CPU 40a acquires the value of the second random number (step S74). In step S74, the main control CPU 40a acquires the value of the second random number updated in the main control RAM 40c.

  Thereafter, the main control CPU 40a generates a hit determination random number used in the big hit lottery or the small hit lottery (step S75). In step S75, the main control CPU 40a generates a hit determination random number based on the sum of the value of the first random number and the value of the second random number (first random number + second random number).

  Then, the main control CPU 40a stores the value of the generated hit determination random number in the storage area of the main control RAM 40c (step S76), and ends the special symbol input process. In step S76, the value of the winning determination random number is stored in the main control RAM 40c, whereby the special symbol variation game is put on hold. Then, the starting condition of the symbol variation game is established. In step S76, the main control CPU 40a adds 1 to the reserved storage number as the hit determination random number value is stored in the main control RAM 40c.

Next, the special symbol start process will be described.
As shown in FIG. 9, the main control CPU 40a determines whether or not an execution start condition is satisfied (step S81). In step S81, the main control CPU 40a determines whether or not a special symbol variation game is not being executed and a winning game (a big hit game or a small hit game) is not occurring. When the determination result of step S81 is negative, the main control CPU 40a ends the special symbol start process.

  On the other hand, if the determination result of step S81 is affirmative, the main control CPU 40a reads the number of reserved memories and determines whether or not the number of reserved memories is greater than “0 (zero)” (step S82). When the determination result of step S82 is negative, the main control CPU 40a ends the special symbol start process. On the other hand, if the determination result of step S82 is affirmative, the main control CPU 40a subtracts 1 from the reserved storage number (step S83). Subsequently, the main control CPU 40a reads the hit determination random number value stored first among the hit determination random number values stored in the storage area of the main control RAM 40c (step S84).

  Thereafter, the main control CPU 40a determines whether or not it is a big hit (step S85). In step S85, the main control CPU 40a determines whether or not the read value of the hit determination random number matches the jackpot determination value stored in the main control ROM 40b, and performs a big hit lottery. If the determination result in step S85 is affirmative, that is, if a big hit is obtained, the main control CPU 40a determines a big hit symbol to be stopped and displayed on the special symbol display device 112 or a variation pattern (step S86), and a special symbol start process. Exit.

  On the other hand, when the determination result of step S85 is negative, the main control CPU 40a determines whether or not a small hit is made (step S87). In step S87, the main control CPU 40a determines whether or not the read hit determination random number value matches the small hit determination value stored in the main control ROM 40b, and performs a small hit lottery. If the determination result in step S87 is affirmative, that is, if a small hit is obtained, the main control CPU 40a determines a small hit symbol to be stopped and displayed on the special symbol display device 112 or a variation pattern (step S88), and the special symbol. End the start process.

  In the present embodiment, the processing of step S85 to step S86 is performed prior to the processing of step S87 to step S88, but the processing of step S87 to step S88 is performed prior to the processing of step S85 to step S86. You may go. In this case, after determining whether or not it is a small hit, it is determined whether or not it is a big hit.

  If the determination result in step S87 is negative, that is, if it is out of place, the main control CPU 40a determines the off symbol or variation pattern to be stopped and displayed on the special symbol display device 112 (step S89), and starts the special symbol. The process ends.

  The main control CPU 40a that has determined the special symbol and the variation pattern in the special symbol start process outputs a control command generated according to the determined content to the sub control CPU 41a at a predetermined timing. Specifically, the main control CPU 40a outputs a variation pattern designation command designating a variation pattern and instructing the start of the special symbol variation game to the sub control CPU 41a. Further, the main control CPU 40a outputs a special symbol designation command for designating the special symbol determined in the special symbol start process to the sub control CPU 41a.

  Then, the main control CPU 40a outputs an end command for instructing the end of the special symbol variation game to the sub control CPU 41a when the variation time set in the instructed variation pattern has elapsed, and stops the determined special symbol. The display content of the special symbol display device 112 is controlled so as to be displayed.

  Further, the main control CPU 40a controls the open state and the closed state of the big winning opening 118 after the end of the symbol variation game that is a big hit, and causes the big hit game to occur. Further, the main control CPU 40a controls the open and closed states of the big prize opening 118 after the end of the symbol variation game that is a small hit, and causes a small hit game to occur.

  Further, when the sub-control CPU 41a inputs the variation pattern designation command and the special symbol designation command, the sub-control CPU 41a determines the symbol combination of the ornament symbols to be stopped and displayed on the ornament symbol display device 111 according to the instruction content of the command.

  In addition, when the change pattern designation command is input, the sub-control CPU 41a controls the display content of the decoration symbol display device 111 so that the decoration symbol of each column is variably displayed and the decoration symbol variation game is started. Then, when the end command is input, the sub control CPU 41a causes the decorative symbol display device 111 to stop-display the symbol combination of the decorative symbols determined to be confirmed and stopped.

  In addition, when the big hit game is generated, the sub-control CPU 41a displays the display pattern of the decorative symbol display device 111 and the sound of the speaker SP so that a predetermined big hit effect is executed until the big hit game ends. The output mode and the light emission mode of the decorative lamp LA are controlled.

  Hereinafter, the present embodiment has the effect of replacing “winning information lottery” with “winning lottery” in the effects (1) to (6) of the first embodiment. Incidentally, in the present embodiment, winning the big hit lottery or winning the small hit lottery corresponds to an advantageous lottery result. In this case, not winning the big hit lottery and the small lottery lottery (being lost) corresponds to a lottery result that is less advantageous than the advantageous lottery result.

  Note that the advantageous lottery result may not be both winning the big hit lottery and winning the big hit lottery. For example, the winning lottery result may be an advantageous lottery result. In this case, in the effects (1) to (6) of the first embodiment, the “winning information lottery” is replaced with “big hit lottery”. Similarly, in the case where the winning lottery result is an advantageous lottery result, the effect of replacing “winning information lottery” with “small lottery” in the effects (1) to (6) of the first embodiment. Play.

In addition, the said embodiment can be actualized in another embodiment (another example) as follows.
-In addition to the bonus game ending condition established by paying out game media exceeding the maximum payout number, the bonus game ending condition of the first embodiment is established by playing a variable game of a prescribed number of games. A game end condition, a bonus game end condition established when a predetermined symbol combination is stopped and displayed, and the like can also be set.

The first embodiment may be embodied in a spinning-type game machine that uses a game ball (pachinko ball) as a game medium.
A setting device may be provided in the slot machine 10 of the first embodiment. The setting device is connected to the main control CPU 40a. The setting device is preferably disposed inside the slot machine 10 and cannot be operated by the player. Then, the setting state of the slot machine 10 may be changed by operating the setting device when the power to the slot machine 10 is turned on. By changing the setting state of the slot machine 10, it is possible to change the winning probability (that is, the probability that the display result is allowed) of at least some of the winning information among a plurality of types of winning information. .

  The second embodiment may be applied to a pachinko gaming machine that performs only one of a big hit lottery and a small hit lottery. For example, the present invention may be applied to a pachinko gaming machine that performs only the big hit lottery among the big hit lottery and the small hit lottery.

  -In the said 2nd Embodiment, you may perform reach lottery of whether to perform reach production (specific production) in a symbol change game. Further, a reach lottery may be performed using the value of the second random number. In the following description, “use the value of the second random number” uses other numerical information (for example, the value of the first random number) and the value of the second random number in addition to using only the value of the second random number. Also intended. In this case, by updating the value of the second random number in the above embodiment, it is possible to suppress the creation of a situation where the reach effect is difficult to be executed illegally or a situation where the reach effect is easily executed illegally.

  In the second embodiment, the variation pattern may be determined using the value of the second random number. In this case, by updating the value of the second random number in the above embodiment, the variation time of the symbol variation game per time is illegally shortened, or the variation time of the symbol variation game per time is illegally increased. Can be suppressed.

  In the second embodiment, a start port having an opening / closing member may be provided as a start port that can be given a start condition for the symbol variation game, such as the start port 115. At this time, a start opening having an opening / closing member may be provided instead of the start opening 115, or a start opening having an opening / closing member may be provided in addition to the start opening 115. The opening / closing member includes a first state (open state) in which a game ball is likely to enter the start opening having the opening / closing member, and a second state in which the game ball is less likely to enter the start opening having the opening / closing member than in the first state. The state (closed state) is configured to be displaceable. Then, a second random number may be used in a lottery (so-called normal winning lottery) to determine whether or not the opening / closing member is displaced to the first state. In this case, it is possible to prevent the opening / closing member from being illegally displaced to the first state by updating the value of the second random number in the above embodiment.

-You may change the 1st prescribed value-the 3rd prescribed value in the above-mentioned embodiment.
In the above embodiment, the value of the random number (hereinafter referred to as “sub lottery random number”) is updated in the sub control RAM 41c in the same manner as the method of updating the value of the second random number in the main control RAM 40c. You may comprise. Then, the sub control CPU 41a may be configured to perform a lottery that can derive an advantageous lottery result using the sub lottery random number. Further, when the sub lottery random number is performed using the first random number that is a hardware random number in addition to the second random number as in the above embodiment, it is preferable to arrange a random number generator on the sub control board 41. .

  In the slot machine as shown in the first embodiment, the “lottery from which an advantageous lottery result can be derived” performed by the sub-control CPU 41a includes, for example, a ceiling game lottery, an ART lottery, an AT lottery, and the like. The ceiling game number lottery is a lottery for determining the number of variable games until the bonus winning information is forcibly won and the number of variable games until the game state is forcibly shifted to a game state advantageous to the player. . The ART lottery and AT lottery are lotteries for determining the transition to a gaming state that is advantageous to the player. As a gaming state that is advantageous to the player, for example, when the payout winning information is won, the operation mode (operation order and operation timing) of the stop button 23 for displaying the stoppage of the payout combination on the winning line NL. There is a gaming state where an operation notification effect (so-called navigation effect) is easily performed.

  In the pachinko gaming machine as shown in the second embodiment, the “lottery capable of deriving an advantageous lottery result” performed by the sub-control CPU 41a includes, for example, an effect lottery capable of determining execution of a rare effect. In the effect lottery that can determine the execution of the rare effect, the determination of the execution of the rare effect corresponds to a lottery result advantageous to the player.

  In the above embodiment, the value of the second random number is used in the lottery for deriving an advantageous lottery result. However, the value of the second random number is not necessarily used in the lottery for deriving an advantageous lottery result. For example, the value of the second random number may be used in a lottery to derive an unfavorable lottery result. In addition, as a lottery for deriving an unfavorable lottery result, there is a lottery (for example, a falling lottery) in which a transition from an advantageous state to an unfavorable state is determined. In the case of such a configuration, it is possible to obtain an effect that it is possible to prevent an illegal disadvantageous lottery result from being derived and to prevent an illegally disadvantageous lottery result from being derived.

In the above embodiment, the first random number may be a software random number. Further, the second random number may be a hardware random number.
In the above embodiment, the first random number value may be updated by the same updating method as the second random number.

  In the above embodiment, the chip individual number register address corresponding to the unique identification information may not be stored in the main control ROM 40b. For example, the chip individual number register address may be configured to be stored in the main control RAM 40c. . In this case, the main control RAM 40c functions as a unique identification unit.

  In the above embodiment, the information to be rotated in Step S52 (in the above embodiment, the individual number) may be all of the individual numbers constituting the chip individual number register address corresponding to the unique identification information. . Further, the information to be rotated (reference numerical value information) may not be the chip individual number register address or the individual number constituting the chip individual number register address. For example, the value of the R register or the value of the second random number before update may be rotated.

  In the second random number update process of the above embodiment, after determining the number of effects, the number of effects is stored in the B register, and the process after step S58 is performed to update the value of the second random number as the specific numerical information. You may comprise. At this time, when determining the number of effects, it may be configured such that the number of effects is determined by lottery from the number of times that can be determined as the number of effects, or the effects are changed so that the number of effects is changed in a predetermined order. The number of times may be determined. In such a configuration, the main control CPU 40a does not rotate the reference numerical value information in the second random number update process, and the rotate information is not derived in the second random number update process. In addition, when determining the number of effects based on the chip individual number register address (or individual numbers constituting the unique identification information) as unique identification information, the identification information assigned to the main control ROM 40b as unique identification means Based on this, the value of the second random number is updated. However, if the number of performances is not determined based on the chip individual number register address (or individual numbers constituting the chip individual number register address), the main control CPU 40a determines the number of effects based on the unique identification information in the second random number update process. It will not be decided. Even in the case of the configuration as described above, if the configuration is such that the number of effects can be changed, the value of the second random number for deriving an unfairly advantageous lottery result is acquired. Can be suppressed.

  -The chip | tip individual number rotation data used in the 2nd random number update process of the said embodiment may not be the information added 1 at a time like the said embodiment. For example, each time the second random number update process is performed (every predetermined cycle), the chip individual number rotation data may be determined regardless of the processing result of the previous second random number generation process. .

  In the above embodiment, the value stored in the A register in step S49, that is, the information used to specify the individual number may not be the value of the R register. For example, a software random number that is incremented (updated by 1) every predetermined cycle is generated in the main control RAM 40c separately from the second random number, and the value of the software random number is stored in the A register in step S49. You may comprise so that it may preserve | save.

  In step S60 of the second random number update process of the above embodiment, the value of the second random number is updated by an operation based on an addition method in which the value of the DE register as the predetermined numerical information is added to the value of the HL register as the basic numerical information. However, the present invention is not limited to the addition method, and the second random number value may be updated by a subtraction method, a multiplication method, or a division method.

  In the above embodiment, when it is desired to suppress a lottery result that is illegally advantageous in the lottery performed by the sub-control CPU 41a, the first random number is a random number generator provided on the sub-control board 41, and the second random number is It is preferable that each of the sub-control RAMs 41c is generated.

  In the above embodiment, a random number (for example, the third random number) different from the first random number or the second random number may be generated by the random number generator 40d or the main control RAM 40c. In addition to the first random number and the second random number, a random number different from the first random number and the second random number may be used in generating the lottery random number and the winning determination random number.

  In the above embodiment, a value based on the chip individual number register address (or the individual number constituting the chip individual number register address) may be configured to be a predetermined value (initial numerical information). Even when configured in this way, this corresponds to updating the specific numerical information based on the identification information.

-In the said embodiment, you may comprise so that the frequency | count of a calculation may be changed by every predetermined period, and may not be changed for every predetermined period.
In the above embodiment, only one of the number of rotations and the reference numerical value information may be changed every predetermined cycle, and at least one may be changed every predetermined cycle. For example, the number of operations can be changed every predetermined cycle. Moreover, in the said embodiment, you may comprise so that both the rotation frequency and reference frequency may not be changed for every predetermined period.

  The basic numerical value information in the above embodiment may not be the value of the second random number updated in the previous second random number update process. For example, the value of the second random number updated in the second random number update process of the previous time Or a value of the first random number.

  In the above embodiment, the chip individual number register addresses assigned to all the main control ROMs need not be different. However, the smaller the number of gaming machines to which the same chip individual number register address is assigned, the more the unauthorized spreading can be suppressed. That is, as the number of chip individual number register addresses increases, unauthorized spreading can be suppressed.

  In the above embodiment, the type of individual number constituting the chip individual number register address may be changed. For example, one type, two types, or ten types may be used. When the number of individual numbers constituting the chip individual number register address is increased so that all individual numbers can be rotated in step S52, there are many kinds of individual numbers constituting the chip individual number register address. It can be suppressed that a lottery result that is more illegally derived is derived. Incidentally, when the individual number constituting the chip individual number register address is one kind, the individual number is the same as the chip individual number register address, and therefore, it can be said that the individual number is unique identification information.

  -In the above embodiment, even if the winning information lottery or the winning lottery is performed using only the second random number of the first random number and the second random number, an illegally advantageous lottery result is derived. Can be suppressed. When the value of the first random number is not used, the random number generator 40d may not be provided.

Next, a technical idea that can be grasped from the above embodiment and another example will be added below.
