  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. As a random number counter provided on the main control board 200, a jackpot random number counter, an initial value random number counter, a jackpot symbol random number counter, a reach random number counter, a special symbol data random number counter, an effect random number counter, a normal symbol random number Counters.

  The jackpot random number counter is used for jackpot determination (game success / failure determination) by the jackpot determination means (win / fail determination means in the present invention), and is composed of random numbers from ‘0’ to ‘629’. The initial value for the first round of update is set to the initial value numerical value calculated by the initial value numerical value calculation process described later based on the game data stored in the RAM (storage means) of the main control board 200. The jackpot random number value in the jackpot random number counter starts from “0” when the gaming machine is turned on or after a reset signal is input to the microcomputer 201 by a reset process (such as a forced reset by operating a reset switch). One is added for each big hit main random number update process (random number update means of the present invention) to be described later, and when it reaches '629', an initial value is newly set and the addition is repeated again. The initial value after the second round is set to the initial value random number value of the initial value random number counter described later. The jackpot random value is acquired due to winning at the start winning opening 42 (establishment of a predetermined opportunity), and the acquired value is set as a jackpot winning value in the low probability state “3”, “397” If it matches any of the above, it will be a big hit, while in the high probability state (privilege gaming state), '3', '53', '113', '173', '227', '281 that are set as the jackpot value If it matches any of ',' 337 ',' 397 ',' 449 ', and' 503 ', it will be a big hit.

  The initial value random number counter is used as an initial value after the second round of the update of the jackpot random number value, and is made up of random numbers for initial values of ‘0’ to ‘629’. The initial value random number value in the initial value random number counter is incremented by 1 for each of the later-described normal symbol / special symbol main random number update processing and jackpot main random number update processing. Return to 'and the second round of updates is performed. The initial random number value is acquired every time the big hit random number value is updated, and is used as the initial value after the second round of the big hit random number update.

  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 of the main random number update process and the big hit 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 turned on or reset, and is incremented by 1 for each of the following normal symbol / special symbol main random number update processing and jackpot main random number update processing. When it reaches 126 ', it is then 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 is incremented by “1” for each of the normal symbol / special symbol main random number update processing and the jackpot main random number update processing, which will be described later, starting from 0 after power-on or after reset processing, When it reaches', then it is rewritten to '0' 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 reset, and is incremented by 1 for each of the later-described normal symbol / special symbol main random number update processing and jackpot main random number update processing. When it reaches '198', it is then 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 hits, and after the game machine 1 is turned on or reset, the normal symbol / special symbol main random number update process and the big hit main random number update process, which will be described later, start from “0”. Is incremented by '1', and 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, a delay process (S10) is performed. The delay process (S10) starts the next process for a time longer than the time until the slave control means (in this embodiment, the sub control board 206, the effect control board 210, and the payout control board 240) can be controlled after the power is turned on. Delay. In this embodiment, the time is set to about 5 s, which is longer than the time required for the sub control means to be controllable.

  Next, based on the game data stored in the RAM (storage means) of the main control board 200, an initial value numerical value calculation process is performed in which a predetermined calculation is performed to calculate an initial value numerical value (S20). In this embodiment, all the games in the RAM that are sequentially stored in the RAM (storage means) of the main control board 200 and saved in the backup area (backup storage area) by the power-off process (S180) described later. The data (binary values) are summed, and the remainder obtained by dividing the total value by the value '630' obtained by adding 1 to the maximum value of the jackpot random number value is calculated as the initial value numerical value. For example, when the total value of the game data (binary values) in the RAM is 30, the remainder 30 is the initial value value, and when the total value is 1100, the remainder 470 is the initial value value. FIG. 23 is an area diagram of the RAM of the main control board 200. The contents assigned to the respective addresses (for example, jackpot random numbers of A01 hold 1 and A05 hold 1) are sequentially stored in the RAM. The stored data in the RAM changes depending on the progress and state of the game (for example, the number of reserved items and the acquired jackpot random value). Each of the RAMs is stored as 2-byte data (denoted in hexadecimal in the RAM area diagram) stored in binary. Depending on the state of the game, the sum of the data (binary values) in the RAM is a random value. In the power-off process at the time of power-off, all data in the control area is stored in the backup area.

  Next, setting of the built-in device (S30) is performed. In the setting of the built-in device, initial setting of various counters of the microcomputer 201 is performed.

  Following the setting of the built-in device (S30), it is determined whether the RAM clear switch 292 is operated (ON), that is, whether a RAM clear signal is input (S40), and the RAM clear switch 292 is ON. The initialization for clearing the data in the backup area in the RAM of the microcomputer 201 is performed (S60). On the other hand, if the RAM clear switch 292 is not ON, it is next determined whether the power-off flag is ON (S50). When the power-off flag is not ON, that is, when the power-off flag is OFF, initialization is performed to clear data in the backup area in the RAM of the microcomputer 201 (S60), while the power-off flag is ON. In this case, data in the backup area in the RAM of the microcomputer 201 is read and set (S70). The initialization process (S60) for clearing the data in the backup area in the RAM is an initialization process for initializing the storage means in the present invention.

  Next, internal register setting and interrupt setting are performed (S80). 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 jackpot random number initial value setting process is performed (S85). The jackpot random number initial value setting process (S85) corresponds to the initial value setting process in the present invention, and the initial value numerical value calculated in the initial value numerical value calculation process (S20) is the same in the jackpot random number value updating means. It is set as the first round random value.

  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 value excluding the big hit random number value is incremented by one for each normal symbol / special symbol main random number update process (S95), and each random value is set as described above. When the upper limit is reached, 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 jackpot major random number update process (S130), the jackpot random number value, jackpot symbol random number value, reach random number value, special symbol data random value, effect random number value, and regular symbol random number value are updated. The initial value of the first round in the jackpot random value is set to the initial value numerical value set in the jackpot random value initial value setting process (initial value setting process S85), and the initial value after the second round in the jackpot random value For each, the update random number value of the initial value random number counter is acquired and set as the initial value of the jackpot random number value every time the update of the jackpot random number value is completed, and the update is performed from the set initial value. The process of acquiring the updated random number value of the initial value random number counter and setting it to the initial value after the second round of the jackpot random number value is the initial value setting means for setting the initial value from the second round of the present invention. It corresponds to. The jackpot random number value, jackpot symbol random number value, reach random number value, special symbol data random number value, effect random number value, normal symbol random number value is incremented by 1 every jackpot main random number update process (S130), and when the upper limit value is reached, The update is continued by returning to the initial value. For random values other than the jackpot random value, 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 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. 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.

  On the other hand, when the loaded reach random number value does not coincide with the reach establishment value, that is, when it is determined that there is no reach, the special out symbol 1 to 1 created in the special out symbol creation process (S160-1). 3 is set (stored) as the storage source address value (S160-5-3-8), and then the special stop symbols 1 to 3 are set as the storage destination address value (S160). -5-3-9), data is transferred from the respective storage source addresses to the corresponding storage destination addresses (S160-5-3-10), and then this special symbol selection processing (S160-5-3) is completed. To do. The special stop symbol 1 is the left special symbol that is stopped and displayed on the special symbol display unit 11, the special stop symbol 2 is the middle special symbol that is stopped and displayed on the special symbol display unit 11, and the special stop symbol 3 is the special symbol. This corresponds to the right special symbol that is stopped and displayed on the display unit 11.

  In the special symbol variation pattern creation process (S160-5-4) performed after the special symbol selection process (S160-5-3), as shown in FIG. 14, first, it is confirmed whether or not the jackpot flag is set to ON. (S160-5-4-1), when the big hit flag is ON, the fluctuation pattern based on the first fluctuation pattern table is selected (S160-5-4-2). On the other hand, when the big hit flag is OFF, The variation pattern based on the two variation pattern table is selected (S160-5-4-3), and then other processing (S160-5-4-4) is performed. This special symbol variation pattern selection processing (S160-5-5) is performed. 4) ends. The first and second variation pattern tables are each provided with a plurality of variation patterns having different variation times as shown in Tables 1 and 2, and each of the plurality of variation patterns has a predetermined range of effect random number values. Is set. The selection of the variation pattern from the first variation pattern table and the second variation pattern table is performed by comparing the effect random number value obtained from the effect random number counter with the effect random number value set for each change pattern. A matching variation pattern is selected. The variation time set in the selected variation pattern is set in the output buffer, and is output as a command (control signal) to the sub-control board 206 in the output process (S110).

  Following the special symbol variation pattern creation process (S160-5-4), a special symbol random number shift process (S160-5-5) is performed. In this special symbol random number shift process (S160-5-5), in the data storage area of the special symbol variation holding ball number (the number of times the determination condition is satisfied) in the RAM, the storage area of the address having the highest load (reading) order is stored. Due to the fact that the stored data of the special symbol variation holding ball number is loaded and vacant by the previous process, the load number of the special symbol variation holding ball stored in the second and subsequent addresses For data, the address is shifted up by one load order. Specifically, as shown in FIG. 15, first, 1 is subtracted from the number of special symbol fluctuation holding balls stored in the RAM of the main control board 200 (for example, the number of holding balls of 2 is set to 1 and 3 (S160-5-5-1), and then the data corresponding to each number of reserved balls is shifted to the RAM address of the number of reserved balls obtained by subtracting 1 from each number of reserved balls (S160). -5-5-2) Subsequently, 0 is set to the RAM address corresponding to the number of special symbol fluctuation holding balls (the number of times the determination condition is satisfied) of the highest rank (the load order is the last, the fourth in this embodiment). (S160-5-5-3).

  Following the special symbol random number shift process (S160-5-5), a special symbol variation start process (S160-5-6) is performed. In the special symbol variation start process (S160-5-6), the special operation status is set to 2 and other processing necessary for starting the variation of the special symbol is performed. After the special symbol variation start process (S160-5-6), the special symbol standby process (S160-5) ends.
