The character ROM 616 stores image data such as sprite / scroll that the VDP 622 that has received an instruction from the CPU 620 develops on the video RAM 614. In the video RAM 614, image data output in the display area of the effect symbol display device 103 by the VDP 622 is developed and temporarily stored. In the present embodiment, the sub-control unit 340 and the display control device 370 are separate devices. However, the present invention is not limited to this, and the sub-control unit 340 and the display control unit 370 are integrally configured to perform display control. The CPU 514 of the control unit 340 can also perform the same control as the lamp control and voice control.

(Game processing executed by the main control unit)
Next, game processing executed by the main control unit 310 of the gaming machine 100 will be described.

(Reset start processing)
First, with reference to FIG. 7, the reset start process at the time of power-on executed by the main control unit 310 will be described. In this process, the CPU 422 and RAM 424 are initialized, the timer interrupt setting process, etc. are performed by the initial power-on processing means, and then the normal gaming state is entered. In the normal gaming state, the first routine of the game control system executed every 4 ms and the second routine of the random number update / lottery system executed every 2 ms are running in parallel.

  First, when the gaming machine 100 is powered on, the main control unit 310 performs an initial value setting process (step S101). Specifically, a value indicating the start of the stack area of the RAM 424 is set in the stack pointer. Next, the main control unit 310 performs CPU function initialization processing for setting an interrupt mode and the like (step S102). Next, the main control unit 310 reads RAM clear switch information indicating whether or not the RAM clear switch 417 has been pressed from the RAM 424 (step S103), and waits until a peripheral device such as the sub control unit 340 is activated. (Step S104).

  Next, the main control unit 310 determines whether or not the RAM clear switch 417 has been pressed based on the RAM clear switch information in order to determine whether or not it is necessary to perform a power recovery process (step S105). If it is determined that the RAM clear switch information is ON and the RAM clear switch is pressed (step S105; YES), the process proceeds to the process at the time of initial power-on after step S109.

  On the other hand, when it is determined that the RAM clear switch information is off and the RAM clear switch 417 is not pressed (step S105; NO), the main control unit 310 determines whether or not the power recovery process can be performed. To do. First, the main control unit 310 determines whether the information generated when the power is turned off is valid by judging whether the backup validity judgment flag in the RAM 424 is valid or invalid (step S106). As a result, when the backup validity determination flag is invalid (step S106; YES), the power recovery process cannot be performed, and the process proceeds to the process at the time of initial power-on after step S109. When the backup validity determination flag is valid (step S106; NO), the main control unit 310 calculates a checksum (step S107), and determines whether or not the sum calculation result matches the sum check buffer (step S107). S108). If they do not match (step S108; NO), the backup data is not normal and the power recovery process cannot be performed, so the process proceeds to the process at the time of initial power-on after step S109. When the sum calculation result matches the sum check buffer and the backup data is normal (step S108; YES), the main control unit 310 performs a power recovery process. In the power recovery process, the main control unit 310 sets information indicating backup invalidity (for example, clearing, etc.) in the backup validity determination flag in order to release the information on occurrence of power interruption (step S112), and then the composite sub A return process is performed (step S113). Specifically, the main control unit 310 transmits a command for instructing the return to the sub-control unit 340 and prepares a payout start instruction command to the payout control unit 450. Next, the main control unit 310 performs initial setting at the time of power recovery of the RAM 424 using the backup data retained when the power is turned off (step S114).

  On the other hand, in the process at the time of initial power-on in steps S109 to S111, the main control unit 310 initializes the RAM 424 (step S109) and then initializes the RAM 424 (step S110). Specifically, the main control unit 310 causes the display control means to display on the special symbol display device 102 an initial symbol that is a power-on selection symbol that is not selected in the normal game shown in FIG. The initial symbol data for reading is read from the table of the ROM 420 and set in the “special symbol display symbol” of the RAM 424. Further, the main control unit 310 sets commands (model discrimination command, initialization command, etc.) for initial setting of the sub control unit 340 in the command storage area of the RAM 424.

  Next, the main control unit 310 reads the command set in the command storage area in step S110 and transmits it to the sub-control unit 340 (step S111).

  After the above-described power recovery process or initial power-on process, the main control unit 310 performs a CTC initial setting process for enabling a CTC interrupt, which is a counter / timer that performs a periodic interrupt (step S115). . Specifically, the CTC register is set so that a timer interrupt is periodically generated every 2 ms. Next, the main control unit 310 sets the interrupt prohibition so as not to interrupt (step S116), the power interruption occurrence check process (step S117), the initial value update random number update process (big hit random number, special symbol random number, normal symbol random number) After updating the random number per map) (step S118), the interrupt is set to permit (step S119), and other random numbers are updated (variation pattern random number, reach random number, etc.) (step S120).

  Next, the main control unit 310 reads the interrupt number counter of the second routine from the RAM 424 (step S121). When the interrupt number counter of the second routine is 2 or more (step S122; NO), after clearing the interrupt number counter (step S123), the first routine of the game control system from step S124 to S131 is executed. Run. On the other hand, when the number of interruptions of the second routine is less than 2 (step S122; YES), the process returns to step S116 and the process is repeated. As a result, the first routine is executed every 4 ms.

  In the control board output process of step S124, the main control unit 310 transmits the command created in the special game management process of step S127 and stored in the command storage area of the RAM 424 to the sub control unit 340. By transmitting the information (command) set in the previous interrupt process in the current interrupt process, the information can be reliably transmitted. Furthermore, the processing is performed more reliably by performing processing at an initial stage in the first routine.

  Next, the main control unit 310 initializes the RAM 424 in order to execute the processing after step S126 (step S125). Specifically, the main control unit 310 performs clear processing of output information such as a solenoid.

  Next, the main control unit 310 performs prize ball payout management processing (step S126). In this process, the main control unit 310 receives a winning result for the first winning winning port 104 or the second starting winning port 108 stored in the RAM 424, a winning result for the big winning port 109 during the big hit operation, And the number of prize balls to be paid out is determined on the basis of the result of winning in the other winning opening. Then, the main control unit 310 transmits a payout control command to the payout control unit 450 to instruct the payout of the prize ball from the prize ball payout device 452.

  Next, the main control unit 310 performs special game management processing (step S127). In this process, only when there is a start winning prize, a process related to the change control of the symbol and the operation control of the special winning opening 109 is performed. This process is not performed when the power is initially turned on.

  Specifically, at the time of starting the variation of the special symbol due to winning at the first starting winning port 104 or the second starting winning port 108 or holding the reserved ball, the main control unit 310 reads from the symbol random number loop counter of the RAM 424. A command to be transmitted to the sub-control unit 340 based on a design determination random number for determining a stop symbol to be read, a hit determination random number read from a hit random number loop counter, or a hit determination random number stored in a holding memory The symbol data for displaying the stop symbol of the special symbol is read from the ROM 420 and stored in a predetermined area (command storage area, “special symbol display symbol”, etc.) of the RAM 424. In addition, during the big hit game, the main control unit 310 stores the big prize opening data and the big prize opening closing data for instructing the big prize opening operating solenoid 446 to open the big prize opening 109 for a predetermined time. To remember. Further, the main control unit 310 controls the special symbol of the special symbol display device 102 for a predetermined variation time via the special symbol display output port 432, and is a symbol specified by the “special symbol display symbol” in the RAM 424. Stop.

  Next, the main control unit 310 performs a normal game management process (step S128). Specifically, when the game ball passes through the normal symbol display device operation gate (left) 105 or the normal symbol display device operation gate (right) 106 and the normal symbol starts to change, the main control unit 310 stores it in the RAM 424. Based on the normal random number of the normal symbol, the stop symbol data of the normal symbol is prepared.

  Next, the main control unit 310 performs external information output processing (step S129). In this process, the main control unit 310 transmits game state information to the outside of the gaming machine such as a hall computer via the external information output unit 454.

  Next, the main control unit 310 performs output management processing (step S131). Port output processing related to direct control is performed here. Specifically, when the power is initially turned on, the main control unit 310 uses the special symbol display output port 432 to display the special symbol data set in the “special symbol display symbol” in the RAM 424 via the special symbol display output port 432. By outputting to the display device 102, the initial symbol shown in FIG. 4E is displayed on the special symbol display device 102. This initial symbol data is set to “special symbol display symbol” in the RAM 424 in the power-on initial setting ram set processing in step S110.

  In this way, when the power is initially turned on, the special symbol display device 102 displays the initial symbol dedicated to the initial power-on, and the symbol displayed on the special symbol display device 102 in the special game management process in step S127 during the game By distinguishing, the player is prevented from being confused by seeing the special symbol displayed on the special symbol display device 102 when the power is initially turned on, and the trouble between the player and the game store is prevented.

  Further, during the big hit game, the main control unit 310 instructs the big prize opening solenoid 446 to open or close the big prize opening 109 based on the big prize opening release data and the big prize opening closing data stored in the RAM 424. . In addition, the main control unit 310 instructs the ordinary electric accessory solenoid 448 to open or close the second start winning opening 108.

  When the processing up to step S131 is completed, the processing returns to step S116, and the processing from step S116 to step S131 is repeated.

(Variation start processing)
Next, with reference to FIG. 8, the change start process combining the change start waiting process in the special game management process of step S127 shown in FIG. 7 and the lottery process in the second routine will be described.

  First, the main control unit 310 reads a special symbol operation memory counter from the RAM 424, and determines whether or not there has been a start winning (step S301). If it is determined that there has been a start prize (step S301; YES), the reserved memory is read from the RAM 424, and it is determined whether or not four or more pieces of information are stored in the reserved memory (step S302). If the number is less than 4 (step S302; NO), the winning random number is obtained from the winning random number loop counter by the lottery means, and the big hit determined random number storages 0, 1, 2, and 3 of the reserved memory are stored in vacant areas. The big hit random numbers are stored in the order of big hit random numbers 0, 1, 2, 3 (step S303).

  Next, the main control unit 310 determines whether the symbol is changing (step S304). If the symbol is not changing (step S304; NO), the main control unit 310 determines whether there is a hold (step S305). When information is stored in the holding memory and it is determined that there is a holding (step S305; YES), a special symbol jackpot determination process for determining the lottery result (step S307), a stop symbol after the special symbol change is determined Stop symbol determination processing (step S308) to be performed, and variation pattern determination processing (step S309) to determine the symbol variation pattern.

  Next, the main control unit 310 transmits a variation pattern type designation command corresponding to the variation pattern determined in the variation pattern determination process in step S309 to the sub-control unit 340 (step S310), and the stop symbol determination process in step S308. A stop symbol type designation command corresponding to the stop symbol determined in is transmitted to the sub-control unit 340 (step S311).

(Special symbol jackpot determination process)
Next, with reference to FIG. 9, the special symbol jackpot determination process in step S307 of the fluctuation start process shown in FIG. 8 will be described.

  First, the main control unit 310 sets an initial value “00H” as a flag value (step S401), and stores the flag value in the big hit flag and the small hit flag of the RAM 424 (step S402, step S403), so that the big hit Initialize the flag and small hit flag.

  Next, the main control unit 310 reads out, from the RAM 424, the hit determination random number stored in the big hit determination random number memory 0 among the big hit determination random number memories 0, 1, 2, and 3 in the reserved memory as the big hit determination random number value (step S404). Further, the main control unit 311 reads the jackpot value stored in the ROM 420, and compares the jackpot value with the jackpot determination random value (step S405). If they match as a result of the comparison (step S405; NO), since the lottery result is a big hit, "01H" is stored in the big hit flag of the RAM 424 as information indicating that the big win has been reached (steps S406, S407). . On the other hand, if they do not match (step S405; YES), since the lottery result is a small hit, “01H” is stored in the small hit flag of the RAM 424 as information indicating that the small hit is reached (steps S408, S409). ). After the big hit determination random number memory 0 is read, the big hit determination random number memory 1 is updated with the hit determination random number stored in the big hit determination random number memory 2, and the big hit determination random number memory 2 is stored in the big hit determination random number memory 3. By updating the hit determination random number and deleting the hit determination random number set in the big hit determination random number memory 3, the information in the reserved memory is shifted to the left.

  As described above, in this special symbol jackpot determination process, if the jackpot value and the jackpot determination random number value match, it is determined to be a jackpot, and if they do not match, it is determined to be a jackpot. Thus, in this embodiment, the determination that the determination result does not deviate is performed.

(Stop symbol determination process)
Next, the stop symbol determination process in step S308 of the variation start process shown in FIG. 8 will be described with reference to FIG.

  First, after setting “7” in the symbol number data (step S501), the main control unit 310 determines whether or not the lottery result is a big hit (step S502).

  When the lottery result is not a big hit (step S502; NO), and when it is a small round of three rounds (step S503; YES), the main control unit 310 is special among the nine symbols shown in FIG. 4 (c). The symbol to be stopped and displayed on the symbol display device 102 is selected by lottery, and the symbol number data is updated with the identification information of the selected symbol (step S504).

  When the lottery result is a small hit of 8 rounds (step S503; NO, step S505; YES), the main control unit 310 causes the special symbol display device 102 to display the nine symbols shown in FIG. The symbol to be stopped and displayed is selected by lottery, and the symbol number data is updated with the identification information of the selected symbol (step S506).

  When the lottery result is a small hit of 16 rounds (step S503; NO, step S505; NO), the main control unit 310 causes the special symbol display device 102 to display the nine symbols shown in FIG. The symbol to be stopped is selected by lottery, and the symbol number data is updated with the identification information of the selected symbol (step S507).

  Finally, the main control unit 310 stores the information set in the symbol number data in any of the steps S501, S504, S506, and S507 in the “special symbol stop symbol” of the RAM 424 (step S508).

  As described above, in the stop symbol determination process, “7” is determined as the stop symbol of the special symbol when the lottery result is a big win, and the stop symbol is determined according to the number of rounds when the lottery result is a small hit. The

(Special symbol change processing)
Next, in the special game management process shown in FIG. 7, a special symbol changing process executed after the change starting process shown in FIG. 8 will be described with reference to FIG. This process is executed by the display control means of the main control unit 310.

  First, the main control unit 310 determines whether or not the special symbol variation time has ended (step S601). If the fluctuation time has not ended (step S601; NO), the main control unit 310 updates the special symbol display switching time to be counted by the timer to 100 ms in order to blink the special symbol during fluctuation. In step S602), the special symbol display switching time is monitored for 100 ms. When the special symbol display switching time of 100 ms has elapsed (step S603; YES), if the data indicating the lighting display of the changing symbol shown in FIG. 4F is set in the “special symbol display symbol” of the RAM 424. The special symbol display symbol is updated to the data that designates the light-off display, and when the data that designates the light-off display is set in the special symbol display symbol, the special symbol display symbol is displayed. The data is updated to data designating the lighting display of the changing symbol shown in 4 (f) (step S604). The data set in the “special symbol display symbol” is output toward the special symbol display device 102 in the special game management process of step S127 every time the first routine is repeated. As a result, the special symbol display device 102 alternately turns on and off the changing symbol shown in FIG.

  On the other hand, when the variation time has ended (step S601; YES), the “special symbol stop symbol” determined in the stop symbol determination process shown in FIG. 10 is set as the “special symbol display symbol” in the RAM 424 (step S605). As a result, the symbols determined in the stop symbol determination process are stopped and displayed on the special symbol display device 102.

  As described above, the symbol blinks during symbol variation, and the symbol determined by the stop symbol determination process is stopped when the variation ends.

(Big hit processing)
Next, with reference to FIG. 12, the jackpot process executed by the jackpot operating means after the special symbol changing process shown in FIG. 11 in the special game management process shown in FIG. 7 will be described.

  When the stop symbol of the special symbol is “7” and the jackpot is reached, the main control unit 310 transmits a jackpot start command to the sub-control unit 340 (step S701). Receiving the jackpot start command, the sub-control unit 340 performs effect control at the start of the jackpot.

  Next, when the big hit start effect time has elapsed (step S702; YES), the main control unit 310 opens the big prize opening 109 (step S703), and transmits a big prize opening release command to the sub-control unit 340 (step S703). S704). Next, when the big prize opening time has elapsed (step S705; YES), the main control unit 310 closes the big prize opening 109 (step S706).

  When the special winning opening closing time has elapsed (step S707; YES), the main control unit 310 determines whether or not the number of continuous operations (number of rounds) in which the special winning opening 109 has been continuously operated has reached 16 or more. Determination is made (step S708). If it is less than 16 times (step S708; YES), the big prize opening 109 is repeatedly opened and closed until it becomes 16 times or more, and if it becomes 16 times or more (step S708; NO), the main control unit 310 ends the big hit The command is transmitted to the sub control unit 340 (step S709). Receiving the jackpot end command, the sub-control unit 340 performs effect control at the end of the jackpot. When the big hit end effect time has elapsed (step S710; YES), the main control unit 310 ends the process.

(Small hit processing)
Next, with reference to FIG. 13, of the special game management process shown in FIG. 7, the small hit process executed by the small hit operation means after the special symbol changing process shown in FIG.

  When the special symbol stop symbol is other than “7” and the lottery result is a small hit, first, the main control unit 310 opens the grand prize opening 109 once (step S801) and opens the first big prize opening. The command is transmitted to the sub control unit 340 (step S802). Next, the main control unit 310 times the first winning opening time of the big winning opening (step S803), and closes the big winning opening 109 when the first winning opening time has elapsed (step S803; YES) (step S804). ).

  Next, the main control unit 310 times the small hitting operation time (step S805), and when the small hitting operation time has elapsed (step S805; YES), the game ball that won the big winning opening 109 has passed through the V region 114. It is determined whether or not (step S806). When it is determined that the vehicle has passed the V region 114 (step S806; YES), a big hit is made, and the main control unit 310 executes the big hit process shown in FIG. 12 (step S807). In the small hit processing, the number of continuous operations in step S708 of the big hit processing may be 3 times and 8 times in addition to 16 times depending on the lottery result.

  As described above, the gaming machine 100 is provided with a winning random number for selecting either a big hit or a small hit, and during the game, the starting random number of the game ball is used as a trigger. When the lottery is performed, the lottery result is always a big hit or a small hit, and the winning symbol corresponding to the big hit or the small hit is stopped and displayed on the special symbol display device 102, and the changing symbol is blinked during the symbol variation. On the other hand, only when the power is initially turned on, an initial symbol dedicated to initial power-on that is not selected during the game is displayed. Thus, by distinguishing the initial symbol displayed on the special symbol display device 102 when the power is initially turned on from the symbol displayed during the game, in the gaming machine 100 in which only winning is selected, It is possible to prevent troubles between the player and the amusement store by displaying symbols without causing any confusion.

  In the above-described embodiment, the initial symbol is displayed on the special symbol display device 102 when the power is initially turned on. However, the display device that displays the initial symbol is not limited to the special symbol display device 102. For example, the initial symbol is displayed. It may be displayed on the effect symbol display device 103. In this case, in the power-on initial setting ram set process in step S110 shown in FIG. 7, a command for designating display of the initial symbol is set in the area for initialization command or model discrimination command in the RAM 424. The set command may be transmitted to the sub-control unit 340 in the control board output process. The sub control unit 340 that has received the command further transmits a command to the display control unit 370, and the display control unit 370 that has received the command controls the effect symbol display device 103 to display the initial symbol. .

  The initial symbol may be displayed on both the special symbol display device 102 and the effect symbol display device 103 when the power is initially turned on.

  In the above-described embodiment, the initial symbol shown in FIG. 4E is displayed on the special symbol display device 102 when the power is initially turned on. However, the initial symbol to be displayed is not limited to this, and the game Any symbol may be used as long as the symbol can be distinguished from the winning symbol so as not to misunderstand that the person wins when the power is initially turned on. Furthermore, as in the above-described embodiment, if the initial symbol is different from the changing symbol, it is more preferable that the player will not misunderstand that the symbol is changing when the power is initially turned on. Further, when the initial symbol is displayed on the effect symbol display device 103, since there are many types of effect symbols displayed on the effect symbol display device 103 during the game as compared to the special symbol, the initial symbol is displayed. It is considered preferable that the symbol is different from the effect symbol displayed during the game with the least confusion of the player.
