In addition to the variation pattern, symbol data, and the like regarding the variation display in the section 11, the big hit and small hit judgment values are written.

  The random number generation circuit 202 built in the microcomputer 201 is a means for generating a random number value (big hit random number value) related to whether the game is successful (big hit). The random number generation circuit 202 can be any one that updates a random number value at a clock cycle and one that is updated by software. In this embodiment, the random number generation circuit 202 is updated at a clock cycle. Yes. The random number generation circuit 202 that updates at the clock cycle can generate random values from “0” to “4094”, and arbitrarily set the maximum random number value within the range from “4” to “4094”. It can be set. In the present embodiment, a random value is set in a range of “0” to “629”. For the first round random value, the initial value (start value) and the update order (arrangement) are fixed values that cannot be changed. The initial value in the first round is fixed to “0”, and the update order is fixed to +1. From the second round, it can be changed by setting the initial value and the update order in advance. In this embodiment, an identification symbol (ID number) is individually set in the microcomputer, and an initial value from the second round is automatically set based on the identification symbol. In this embodiment, the update order is not changed in the second and subsequent rounds, and is +1 as in the first round.

  The update cycle by the random number generation circuit 202 in this embodiment is 112 microseconds, and the time required for the random number value of the random number generation circuit 202 to make one round from the initial value at the start of update, that is, the initial value “0” in the first round. It takes 112 microseconds × 630 to complete a round of update from “1” to “629”, which requires 70560 microseconds. In order to prevent the random number value from being acquired and determining whether or not the random number is correct (a jackpot determination) until the random number value of the random number generation circuit 202 is updated from the initial value in the first round to the first round. In the control board 200, a first delay process to be described later, which waits for a predetermined time (delays the next process), is performed. Further, in the first delay processing in the present embodiment, a slave control means (slave control board) that controls a game according to a control signal output from the master control board (main control means) 200 for a predetermined time to wait (delay). 206, the payout control board 240, etc.) are set to a time longer than the time (rise time) required until the gaming machine is in a controllable state after the power is turned on. Since the time from the initial value in the first round of the random number value in the first round in the random number generation circuit 202 to the one round update is longer, the delay process for the random number generation circuit 202 is followed by the first delay process described later. It also serves as a delay process for starting up the control means. When delay processing for the slave control means is not performed, or when the rise of the slave control means is shorter than the time from the initial value in the first round of the random number value in the random number generation circuit 202 to the time of one round update. Until the random number value of the random number generation circuit 202 is updated from the initial value of the first round until it is updated once, the random number value of the random number generation circuit 202 is acquired, and whether or not the random number is correct (decision determination of jackpot) A first delay process for preventing the random number from being performed is provided exclusively for the delay process for the random number generation circuit 202. In addition, the cycle in which the random number generation circuit 202 updates the random number is set to a cycle shorter than a cycle (4 ms in the present embodiment) in which a game control procedure described later is executed. The random value can be updated regardless of the period of the game, and the random value that is not synchronized with the game can be updated.

  Furthermore, in the present invention, since the predetermined time (first delay time) for waiting (delaying) in the first delay processing is fixed, the time for which the random number value is won in the second and subsequent rounds is further externalized. In order to make it difficult to guess from the above, the random number generation is performed as the second delay process after the first delay process with a constant waiting time (first delay time) and before the game control procedure described later is executed. The random number value is acquired from the circuit 202, and the start of the next processing is delayed by the time (second delay time) consisting of the value. By performing the second delay process, the game control procedure at the start of the game has a random time from power-on to execution, and a predetermined trigger is established in the game control procedure (start winning prize opening 42 It is difficult to guess from outside the random time value obtained from the random number generation circuit 202 for determining whether or not the game is successful by winning from the outside, and the random value is won. It is more difficult to cheat on time.

  The random number value updated by the random number generation circuit 202, that is, the jackpot random number value is stored in the RAM of the microcomputer 201, and a prize is awarded to the start winning opening 42 in the game control procedure (a predetermined opportunity in the present invention). Is established, that is, the determination condition is satisfied), and whether or not the acquired jackpot random value is determined is determined. That is, if the acquired jackpot random number value matches either “3” or “397” set as the jackpot value in the low probability state, the success / failure determination result becomes a hit (jackpot), while in the high probability state Any of '3', '53', '113', '173', '227', '281', '337', '397', '449', '503' If it matches, the result of the success / failure determination is a win (big hit), otherwise it is a failure.

  The microcomputer 201 is provided with a reset signal input unit 203 to which a reset signal is input when power is turned on or reset. The reset process is performed when the reset signal is input. When power-on or reset processing is performed, the microcomputer 201 executes the control procedure from the initial control procedure and starts the update by the random number generation circuit 202 from the initial value “0” in the first round as will be described later. In this embodiment, the reset signal is output when it is detected that the voltage of the power supply substrate 250 has become equal to or higher than a predetermined voltage when the power is turned on or when there is an instantaneous interruption of the power. Further, a manual reset switch may be provided in the gaming machine 1 so that it is output when the reset switch is operated.

The power supply board 250 is supplied with AC24V from the outside, converts the input AC24V into DC34V, converts the converted DC34V into DC12V and DC5V by each regulator, and supplies them to each board. When the power is turned on, the primary voltage 34V, which is the basis for generating DC12V and DC5V, is monitored. When the monitored voltage reaches a certain value (18.43V in this embodiment), the voltage is provided on the power supply board 250. A power-off signal (5 V) is output from the first voltage monitoring reset IC to the microcomputer of each board. The reset signal (5v) is output to the microcomputer of each board within 34.9 ms after the power-off signal is output from the second voltage monitoring reset IC provided on the power board 250. Yes. When the microcomputer 201 of the main control board 200 receives a reset signal from the power supply board 250, the microcomputer 201 starts its operation and starts an initial control procedure described later.

  The sub-control board 206 is provided with a DC5V voltage monitoring reset IC, and is configured to output a reset signal within 100 ms after the 5V voltage value reaches a constant voltage value of 3.8V. The microcomputer of the sub-control board 206 can be operated by receiving both reset signals from the power supply board 250 and the sub-control board 206.

  In this embodiment, since the reset signal is output after being delayed from the power-off signal, the game data is surely backed up when the power is turned off. The timing at which the reset signal is output varies slightly but is output at approximately the same time until the game can be started after the power is turned on (the microcomputer 201 of the main control board 200 can start the game control procedure described later). Time is constant. In addition, in the case of an illegal act in which the reset process is performed illegally and hits the first round of big hit random numbers, a reset signal output to the main control board 200 is interposed in the main control board 200 or the like for resetting. After a certain period of time after the signal is output, a radio wave is transmitted from the outside, or a game ball is directly input to the winning device so that the winning signal is output to the main control board 200. In some cases, the player may be hit with a numerical value, and it is possible to prevent such fraud by configuring the time from the output of the reset signal to the start of the game indefinitely.

  The launch control board 260 controls the launch motor in the launch device 64.

  Here, the game in the gaming machine 1 will be briefly described. In the gaming machine 1, when the game balls launched by the launching device 64 toward the game area 6 win the various winning holes, a predetermined number of gaming balls corresponding to the winning holes become upper balls as winning balls. It is paid out to the tray 36. When the game ball passes through the normal symbol variation start gates 55 and 56, a normal symbol random value is acquired, and a normal symbol hit (small hit) determination is performed based on the acquired random value, and the normal symbol is determined. The normal symbol starts to fluctuate on the display unit 50 and stops after fluctuation for a predetermined time. At this time, when the hit determination result of the normal symbol is a small hit, the small hit normal symbol, in this example, stops at an odd number, and the two movable pieces 42a and 42b of the start winning opening 42 are on the back starting winning opening. By the solenoid for use, it is changed from a narrow open state (normal state) that is almost vertical and difficult to win, to a generally V-shaped (reverse C-shaped) open and open state that is easy to win, and it becomes easy for the game ball to win. When a game ball wins the start winning opening 42, a predetermined number of game balls are paid out as a prize ball.

  When a game ball wins the start winning opening 42, a jackpot random number value, a jackpot symbol random number value, and the like are acquired, and a jackpot determination is performed based on the acquired jackpot random number value. The special symbol (determination symbol) starts to fluctuate in the symbol display unit 11, and is stopped and displayed after a predetermined time variation.

  When the result of determining whether or not the jackpot is successful (a jackpot), the special symbol display unit 11 displays a jackpot symbol (a jackpot determination symbol). In this example, “1,1,1” (so-called “1” roar ) Or “2,2,2” (a combination of the same numbers such as so-called “2”), which is advantageous for the player (in this embodiment, the player obtains a game ball) The game shifts to a jackpot game (special game) that grants (easiness increase). In the special gaming state, the open / close plate 46 of the grand prize opening 45 is opened so that the game balls falling on the surface of the gaming area 6 can be easily received, and the prize winning hole 45 can be awarded. When winning 45, a predetermined number of game balls are paid out as prize balls. The opening / closing plate 46 is closed after a predetermined time (for example, 29.5 seconds) has elapsed or when the number of winning balls reaches a predetermined number (for example, 10). Further, when a winning ball to the specific area winning opening 47 in the big winning opening is detected during the opening of the big winning opening 45 or within about 2 seconds after the closing of the big winning opening 45, the big hit is repeated again. A right is generated, and the opening / closing plate 46 is repeatedly opened for a predetermined maximum number of rounds (for example, a maximum of 15 rounds).

  The jackpot includes a normal jackpot and a probable jackpot (special jackpot). In the case of a normal jackpot, the probability of the next jackpot is set to a low probability (1/315 in this embodiment) after the end of the special game, whereas in the case of a probable jackpot (special jackpot) After the game is over, the next jackpot probability is set to a high probability (5/315 in this embodiment). In the case of the normal jackpot, a normal jackpot symbol (ordinary jackpot determination symbol) composed of even numbers such as “2, 2, 2” is displayed on the special symbol display unit 11, while on the other hand, in the case of a probable variation jackpot Is displayed on the special symbol display unit 11 with a probability variation jackpot symbol (special jackpot determination symbol) composed of odd numbers such as “1, 1, 1”.

  Next, the control process of the gaming machine 1 will be described. The random number counter provided on the main control board 200 includes a jackpot symbol random number counter, a reach random number counter, a special symbol data random number counter, a production random number counter, a normal symbol random number counter, and the like. The jackpot random number value is updated every 112 microseconds by the random number generation circuit 202 built in the microcomputer 201 as described above.

  The jackpot symbol random number counter determines a jackpot symbol combination that is confirmed and stopped in the special symbol display unit 11 when the jackpot winning / bad determination result is a hit, from the random numbers from “0” to “7” Become. This jackpot symbol random number value starts with “0” after power-on or after a reset signal is input to the microcomputer 201 by reset processing (forced reset, etc. by operating a reset switch, etc.). 1 is added for each main random number update process, and when it reaches “7”, it is then set to “0” and the addition is repeated again. The jackpot symbol random number value is acquired due to winning at the start winning opening 42. The jackpot symbol random number value is assigned a jackpot symbol combination that is stopped and displayed on the special symbol display section when the jackpot winning / failing determination result is a hit. In the present embodiment, when it is “0”, it is one grove (all the same symbols) where the jackpot symbol combination is “1,1,1”, and when it is “1”, it is “2,2,2”. 2 slots, if '2', 3 slots, '3, 3, 3'; if '3', 4 slots, '4, 4, 4' 5 for eyes, 4 for 5 and 5 for 5; 6 for 6; 6, 6 for 6; In this case, a jackpot symbol combination consisting of 7 grids of “7, 7, 7” and 8 grids of “8, 8, 8” is allocated.

  The reach random number counter is used for determining whether or not a reach state is reached when the jackpot determination result based on the jackpot random number value is out of reach, and is a random number of “0” to “126”. Consists of. The reach state in the present embodiment excludes the special symbol (for example, the middle special symbol) that is stopped and displayed last among the left special symbol, the middle special symbol, and the right special symbol that are displayed with the variable symbol stopped on the special symbol display unit 11. When other special symbols (for example, left special symbol and right special symbol) are the same (excluding the final stop symbol, the state is equal to the jackpot special symbol combination, and finally the jackpot special symbol combination) And a case where a special symbol combination is included. This reach random number starts from “0” when the gaming machine 1 is powered on or reset, and is incremented by 1 for each of the normal symbol / special symbol main random number update processing described later. When the numerical value reaches “126”, Next, it is set to “0” and the addition is repeated again. The reach random number is acquired due to winning at the start winning opening 42, and when the result of the determination is wrong, the numerical value is compared with a predetermined reach establishment value to determine the presence or absence of reach. In this embodiment, reach establishment values are “5”, “17”, “28”, “40”, “51”, “63”, “74”, “86”, “97”, “109”, “ 120 '.

  The special symbol data random number counter is used for determining a special symbol combination to be stopped and displayed on the special symbol display unit 11 when the jackpot determination result based on the jackpot random number value is out, The special symbol data 1 random number counter for determining the left special symbol to be stopped and displayed on the display unit 11, the special symbol data 2 random number counter for determining the middle special symbol, and the special symbol data 3 for determining the right special symbol. Each special symbol data random number counter is composed of random numbers from “0” to “7”.

The random number of the special symbol data 1 starts from 0 after power-on or after reset processing, and is incremented by “1” every time a normal symbol / special symbol main random number update process described later is reached. And the addition is repeated again. The random number of the special symbol data 2 starts from “0” when the power is turned on or after the reset process, and is incremented by “1” when the random number of the special symbol data 1 is rewritten to “0”. When it reaches', then it is rewritten to '0' and the addition is repeated again. Furthermore, the random number of the special symbol data 3 starts from “0” when the power is turned on or after the reset process, and is incremented by “1” when the random number of the special symbol data 2 is rewritten to “0”. When it reaches', then it is rewritten to '0' and the addition is repeated again. Thereby, even if the random number ranges of the special symbol data 1 to 3 are the same, the random numbers of the special symbol data 1 to 3 can be prevented from being synchronized (added in the same combination).

  Each of the random numbers of the special symbol data 1 to 3 is “1” when “0”, “2” when “1”, and “3” when “2”. A judgment symbol consisting of a left special symbol, a middle special symbol, and a right special symbol that are stopped and displayed on the display unit 11 is assigned. The random numbers of the special symbol data 1 to 3 are acquired due to winning at the start winning opening 42, and are displayed on the special symbol display unit 42 when the special symbol data 1 to 3 is removed by a combination of the random numbers of the acquired special symbol data 1 to 3. The judgment symbol consisting of the left special symbol, middle special symbol, and right special symbol is determined.

  The effect random number counter is used when a variation pattern is selected from the first and second variation pattern tables, and has an effect random number value of ‘0’ to ‘198’. This effect random number value starts from '0' when the gaming machine 1 is turned on or after resetting, and is incremented by 1 for each of the normal symbol / special symbol main random number update processing described later, and the numerical value reaches '198'. Then, it is set to “0” and the addition is repeated again. The effect random number value is acquired due to winning at the start winning opening 42.

  As shown in Tables 1 and 2, the first and second variation pattern tables are provided with a plurality of variation patterns. For each variation pattern, the range of the effect random value, the variation time of the special symbol, and the appearance rate in the table are set. The range of the effect random value is the value of the effect random number from which the variation pattern is selected in each table. For example, in the case where the success / failure determination result of the jackpot is successful, if the production random number value is “0” to “194”, the variation pattern 1 is selected, and if the production random number value is “195” to “198”, the variation pattern. 2 is selected, on the other hand, if the result of determining whether or not the jackpot is true, the variation pattern 1 is selected if the production random number value is “0”, and the production pattern varies if the production random number value is “1” to “18”. If the pattern 2 is selected and the production random number value is '19' to '198', the variation pattern 3 is selected. The appearance rate in the table is the appearance rate of each variation pattern, and is a value calculated from the range of the effect random numbers.

  About the acquired jackpot random number value, jackpot symbol random number value, reach random number value, special symbol data random number value, production random number value, respectively, a maximum of four, in the corresponding area in the RAM of the main control board 200, the number of reserved balls Stored in correspondence and used sequentially.

The normal symbol random number counter is used to determine the small hit, and after the game machine 1 is turned on or reset, it starts from “0” and is incremented by “1” for each of the normal symbol / special symbol main random number update processing described later. When it reaches “9”, it is then rewritten to “0” and the addition is repeated again. The normal symbol random numbers are acquired every time the game balls that have passed through the normal symbol variation start gates 55 and 56 are detected by the normal symbol variation start switch, and up to four normal symbols are stored in the RAM of the main control board 200. It is stored in the symbol random number storage area.

  In addition, a normal symbol is assigned to the normal symbol random value. The normal symbol random number value “0” is assigned as “0”, “1” is assigned to “1”, “2” is assigned to “2”, and so on. In the present embodiment, the probability of hitting a small hit is ½. Specifically, when the acquired random number value of the normal symbol random number is an odd number, the hit is small and the start winning opening 42 is expanded. It is designed to open and open. In addition, when the obtained random number value of the normal symbol random number is other than that, it is not a small hit, and the start winning opening 42 is left in the narrow open state where it is difficult to win.

  As main flags provided on the main control board (main control circuit) 200, in this embodiment, a big hit flag, a big hit end flag, a probability change flag, and the like can be cited. These flags are all turned off (not set) at the time of initial setting.

  In the main control board (main control circuit) 200, the microcomputer 201 performs main processing M in accordance with control means (program) stored in the ROM. FIG. 6 is a flowchart of the main process M.

  In the main process M, when a reset signal is input to the reset signal input unit 203 of the main control board 200 by power-on or a reset switch operation, first, an initial control procedure is performed out of the control procedures, and then a game control procedure is performed. Is done.

  In the initial control procedure, first, setting of a built-in device and random number update start processing (S10) of a random number generation circuit are performed. In the setting of the built-in device, initial setting of the RAM and various counters of the microcomputer 201 is performed. In the random number update start processing of the random number generation circuit, the random number generation circuit 202 built in the microcomputer 201 starts operation, and starts the first round random number update at a cycle of 112 microseconds from the initial value “0”. To do.

  Subsequently, a first delay process (S20) is performed. In the first delay process (S20), the random number generation circuit 202 secures a predetermined time (first delay time) set longer than the time for starting the random number update and making a round update from the initial value '0', The process waits until a predetermined time elapses, and delays the start of the process performed after the first delay process (S20). In the present embodiment, the time for the random number generation circuit 202 to start updating the random number and complete a round update from the initial value “0” to “629” is 112 micros × 630 = 70560 micros, so the first delay The predetermined time (first delay time) waiting in the process (S20) is set longer than 70560 microseconds. At the end of the first delay process (S20), the random number value of the random number generation counter 202 has been updated for the first round and has been updated for the second and subsequent rounds. Further, in the present embodiment, the predetermined time (first delay time) to wait in the first delay process (S20) is subordinate control means (sub control board 206, effect control board 210, and payout control board 240 in this embodiment). Is set to about 5 seconds, which is longer than the time required for the time until control becomes possible.

  After the first delay process (S20), it is determined whether the RAM clear switch 292 is operated (ON), that is, whether a RAM clear signal is input (S30), and the RAM clear switch 292 is ON. Initialization is performed to clear the data in the backup area in the RAM of the microcomputer 201 (S50). On the other hand, if the RAM clear switch 292 is not ON, it is next determined whether the power-off flag is ON (S40). When the power-off flag is not ON, that is, when the power-off flag is OFF, initialization is performed to clear the backup area data in the RAM of the microcomputer 201 (S50), while the power-off flag is ON. In this case, the data in the backup area in the RAM of the microcomputer 201 is read and set (S60).

  Next, internal register setting and interrupt setting are performed (S70). In the setting of the built-in register, initial setting of the register is performed, and various flags such as the power-off flag are turned off. In the interrupt setting, settings for interrupt are performed.

  Next, a second delay process is performed (S80). In the second delay process (S80), an updated random number value is acquired from the random number generation circuit 202 and is delayed by the value (second delay time). For example, if the updated random number value acquired from the random number generation circuit 202 is 100, 100 ms is set as the second delay time, and the start of the next process is delayed by 100 ms. In the present embodiment, the second delay time is set to ms corresponding to the random number value acquired from the random number generation circuit 202. However, the second delay time is not limited to this as long as the second delay time can be determined at random. The second delay time may be a result of a predetermined calculation based on the random value acquired from the random number generation circuit 202.

  Next, an interrupt permission process is performed (S90). In the interrupt permission process (S90), an interrupt process (S100) is permitted every 4 msec. The process until the end of execution of the interrupt permission process (S90) corresponds to the initial control procedure.

  Next, the normal symbol / special symbol main random number update process (S95) is performed in a loop process. In the normal symbol / special symbol main random number update process (S95), the random number value other than the jackpot random number value updated by the random number generation circuit 202 is incremented by 1 for each normal symbol / special symbol main random number update process (S95). When the set upper limit value of each random number value is reached as described above, the value returns to “0” and the addition is performed again. The updated random number value is stored in the RAM of the main control board 200.

  The interrupt process (S100) corresponds to a game control procedure among the control procedures performed by the microcomputer 201. In the interrupt process (S100), as shown in FIG. 7, an output process (S110) is first performed. In the output process (S110), the command (control signal) stored in the output buffer of the main control board 200 by each process is output to the corresponding control board or the like. In the subsequent input process (S120), signal input is performed when various sensors (such as detection switches for each winning opening) detected in the gaming machine 1 are detected. In the next normal symbol / special symbol main random number update processing (S130), the same processing as the normal symbol / special symbol main random number update processing (S95) performed in the loop processing in the main processing M is performed. . In the normal symbol / special symbol main random number update process (S130), various random number value update processes excluding the jackpot random number value are performed.

  In the start winning opening switch detection process (S140), as shown in FIG. 8, first, whether or not a game ball has won the start winning opening 42 (whether or not a predetermined opportunity has been established), that is, the starting winning opening 42 is displayed. It is determined whether or not a game ball has been entered and whether or not a game ball has been detected by the start winning port detection switch (S140-1), and if it has not won the start winning port 42, this start winning port switch is detected. The process (S140) ends. On the other hand, when the winning prize opening 42 is won (a predetermined trigger is established, that is, a determination condition is established), the special symbol stored in the RAM of the main control board 200 is used. It is confirmed whether or not the number of change-holding balls (the number of times a predetermined trigger is established, that is, the number of times the determination condition is established) is 4 or more (S140-2). If the number of special symbol variation holding balls is 4 or more, the start winning port switch detection process (S140) is terminated. If the number is less than 4, the starting symbol port switch is set to the number of special symbol variation holding balls. 1 is added to the number of detected game balls detected in (S140-3). Subsequently, a special symbol-related random number acquisition process (S140-4) is performed, and then the start winning a prize opening switch detection process (S140) ends. In the special symbol related random number acquisition process (S140-4), an updated random number value related to the special symbol stored in the RAM is acquired, and the acquired random number value is stored in the RAM address corresponding to the current number of special symbol fluctuation holding balls. Saved (stored). The random number values acquired here are a jackpot random number value, a jackpot symbol random value, a reach random number value, a special symbol data random value, and an effect random number value. The jackpot random number value is updated by the random number generation circuit 202, and the updated random number value stored in the RAM is read, and the acquired random number is saved in the RAM address corresponding to the current special symbol variation holding ball number ( Remembered). Note that the acquired random number value is saved in the RAM address corresponding to the current number of special symbol variation holding balls (the number of times that the determination condition is satisfied). In the case of 1, the acquired random number value (big hit random number value, big hit symbol random number value, reach random number value, special symbol data random number value, effect random number value) is saved in the RAM address corresponding to the number of special symbol fluctuation holding balls 1 If the number of symbol variation holding balls (the number of times the determination condition is satisfied) is 2, it means that the acquired random number value is saved in the RAM address corresponding to the number of special symbol variation holding balls 2.

  In the normal operation process (S150), the normal symbol random number value that has been updated and stored in the RAM is acquired, and the small symbol determination, the normal symbol stop display on the normal symbol display unit 50, the start winning opening 42 is displayed. Although processing relating to small hits such as opening and closing is performed, detailed description is omitted because it is not important for understanding the present invention.

  In the special operation process (S160), as shown in FIG. 9, first, a special out symbol creation process (S160-1) is performed. In the special off symbol creation process (S160-1), as shown in FIG. 10, the address value of the special symbol data 1 acquired in the start winning a prize opening switch detection process (S140) and stored in the RAM is the storage source address. Is set to a value (S160-1-1), and then the special symbol data 3 acquired in the start winning a prize opening switch detection process (S140) and stored in the RAM is loaded as a determination value (S160-1). -2), it is determined whether or not the random value of the special symbol data 3 as the determination value matches the random value of the special symbol data 1 stored in the storage source address value (S160-1-3). . If there is a match, the special out symbol design processing (S160-1) is completed and the special out symbol data is not updated. If they do not match, the data storage destination address value of the special out symbol in the RAM and the special out symbol are stored. Are set as the address values of the special symbol data 1 to 3 (S160-1-4), and the special symbol assigned to the random value of the special symbol data 1 to 3 is The special out symbol data is updated by being transferred to the data storage destination and stored as special out symbols 1 to 3 (S160-1-5), and then the special out symbol generating process (S160-1) is finished. . The special symbol 1 is stopped and displayed on the special symbol display unit 11 when the jackpot determination result is lost, and the special symbol 2 is stopped and displayed on the special symbol display unit 11 when the jackpot determination result is off. The middle special symbol and the special out symbol 3 correspond to the right special symbol which is stopped and displayed on the special symbol display unit 11 when the jackpot determination result is out.

  As shown in FIG. 9, in the special action process (S160), it is determined whether the special action status is 1 to 4 (S160-2 to 160) after the special outlier creation process (S160-1). -4). When the special operation status is 1, a special symbol standby process (S160-5) is performed. On the other hand, when the special operation status is 2, a special symbol variation process (S160-6) is performed. When the special operation status is 3, special symbol confirmation processing (S160-7) is performed, and when the special operation status is 4, special electric accessory processing (S160-8) is performed.

  In the special symbol stand-by process (S160-5), as shown in FIG. 11, it is determined whether or not the number of special symbol variation holding balls (the number of times a predetermined trigger is established and the number of times a determination condition is satisfied) is 0 (S160-). 5-1) Whether or not the special symbol display section 11 is in a standby screen where the special symbol is not changing when the number of special symbol variation holding balls (the number of times a predetermined trigger is established, the number of times the determination condition is established) is 0 (S160-5-7), if the standby screen is displayed, the special symbol standby process (S160-5) is terminated. On the other hand, if the standby screen is not displayed, the special symbol display unit 11 is waited. A setting process for making a screen is performed (S160-5-8), and then this special symbol standby process (S160-5) is terminated.

  On the other hand, if it is determined in S160-5-1 that the number of special symbol variation holding balls is not 0, special symbol jackpot determination processing (S160-5-2) is performed. The special symbol jackpot determination process (S160-5-2) corresponds to the success / failure determination means in the present invention. In the special symbol jackpot determination process (S160-5-2), as shown in FIG. 12, first, the jackpot random number value stored in the RAM of the main control board 200 is loaded as a determination value (160-5). 2-1), the address of the RAM storing the jackpot determination value table that defines the jackpot value at the time of high probability and low probability is set (S160-5-2-2). Subsequently, it is determined whether or not the current probability change is in progress (high probability state) (S160-5-2-3). Whether or not the probability change is in progress is determined by whether the probability change flag provided on the main control board 200 is ON (high probability state) or OFF (low probability state). When the probability change is in progress, it is determined whether or not the jackpot is based on whether or not the jackpot value in the high probability state matches the loaded jackpot random value (S160-5-2-4). If it is not medium, that is, in the low probability state, whether or not the jackpot is established is determined by whether or not the jackpot value in the low probability state matches the loaded jackpot random number value (S160-5-2-5). Then, it is determined that a big hit is made, and the big hit flag provided on the main control board 200 is set to ON (S160-5-2-6). Thereafter, the special symbol jackpot determination process (S160-5-2) ends. If it is determined in S160-5-2-4 or S160-5-2-5 that there is no big hit, this special symbol big hit determination process (S160-5-2) without turning on the big hit flag. Ends.

  After the special symbol jackpot determination process (S160-5-2), a special symbol selection process (S160-5-3) is performed. In the special symbol selection process (S160-5-3), as shown in FIG. 13, it is determined whether or not the big hit flag is ON (big hit) (S160-5-3-1), and the big hit flag is ON (big hit). In this case, a symbol based on the jackpot symbol random number is set as a jackpot symbol to be stopped and displayed on the special symbol display unit 11 (S160-5-3-2), and then this special symbol selection process (S160- 5-3) ends.

  On the other hand, when the jackpot flag is OFF (disconnected), the reach random number value acquired in the start winning a prize opening switch detection process (S140) and stored in the RAM of the main control board 200 is loaded, and the reach It is confirmed whether or not it agrees with the established numerical value (S160-5-3-4), and if it agrees, there is a reach, and is acquired in the start winning a prize opening switch detection process (S140) and stored in the RAM of the main control board 200 The special symbol data 1 is set as the left and right special symbols to be stopped and displayed on the special symbol display unit 11 (S160-5-3-5), and then 1 is added to the special symbol data 1 (S160- 5-3-6), and the added one is set as a medium special symbol that is stopped and displayed on the special symbol display unit 11 (S160-5-3-7). Thereafter, the special symbol selection process (S160-5-3) is completed.

  According to A1, when the power is turned on, the microcomputer executes the game control procedure after performing the initial control procedure. In the initial control procedure, the random number update start for starting the random number update of the random number generation circuit from the initial value is performed. A first delay process that delays the process and the next process by a first delay time is included, the random number update start process is executed before the first delay process, and the first delay time of the first delay process Is set to be longer than the time required for the random number generation circuit to start updating the random number and make a round update from the initial value, and the game control procedure is such that the determination unit determines whether the random number is correct or not when a predetermined trigger is established. Therefore, it is not determined whether the random number value is correct or not by the game control procedure until the random number value makes a round. Rukoto is possible.

  According to A3, the microcomputer includes a reset signal input unit to which a reset signal is input, and executes a control procedure based on the input of the reset signal to the reset signal input unit. The game control procedure until the random number is completed even when the reset signal is output by operating the reset switch with the reset switch for resetting, or when the reset signal is output when the power is turned on Since it is not determined whether or not the random number value is determined according to the above, it is possible to reduce fraud targeting the time when the first round random number value is a hit.

  According to A4, even if the random number generation circuit is a gaming machine in which the initial value of the first round at the start of updating is a fixed value, whether or not the random number value is determined according to the game control procedure is executed until the random number is rounded. Since this is not performed, it is possible to reduce fraud aimed at the time for which the first round random number value is hit.

  According to A5, since the random number generation circuit changes the initial value from the second round after the random number value is updated once, the random number value for the second and subsequent rounds is also targeted at the time when the random number value is hit. Fraud can be reduced.

  According to A6, it is possible to set the initial value of the random number value in the second round to be different for each gaming machine, and it is illegal to measure the time from turning on the power to hit the random value Can be reduced.

  According to A7, after the completion of the initial control procedure, the microcomputer executes the game control procedure every predetermined cycle, and the cycle in which the random number generation circuit updates the random number value is greater than the predetermined cycle in which the game control procedure is executed. Since it is set with a short cycle, the random value can be updated regardless of the cycle of the game control procedure of the microcomputer, and the random value that is not synchronized with the game can be updated.

  According to A8, the first delay time in which the first delay process is delayed is set to be longer than the time required until the slave control means becomes controllable after the power is turned on. The game control procedure is no longer executed until the means becomes controllable. When the main control means executes the game control procedure and outputs a control signal to the slave control means, the slave control means outputs the control signal. It is possible to prevent problems that may be missed.
