In this example, “1,1,1” (so-called “1” gaze) or “ 2,2,2 ”(a combination of the same numbers such as“ 2 ”), which is advantageous to the player (in this embodiment, the player can easily acquire the game ball) Shift to jackpot game (special game) that grants (increased). 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 configured to close after a predetermined time (for example, 29.5 seconds) elapses 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”.

  In addition, after the determination of success or failure, characters or effects other than the special symbol are displayed on the notice display unit 13 of the display device 10 from the start of change to the stop of change of the special symbol (determination symbol) in the special symbol display unit 11. A notice consisting of symbols is displayed. In the present embodiment, when the jackpot winning / failing determination result is winning, one of a plurality of types of characters or effect symbols shown in the notice display content column of the jackpot selection table shown in Table 1 is selected, and the notice display section On the other hand, if the jackpot winning / failing determination result is out of place, one of a plurality of types of characters or effect designs shown in the notice display content column of the outage selection table shown in Table 2 is selected, and the notice Displayed on the display unit 13. The notice display displayed in the notice display unit 13 is different depending on whether the jackpot determination result is a win or not, and the special symbol display unit 11 displays a determination result with a stop special symbol. Before being displayed, the player can predict the result of the determination of the success / failure according to the type (contents) of the advance notice displayed on the advance notice display unit 13. For example, if the success / failure determination result of the jackpot is a winning jackpot, a character such as “It is a big hit” or “Expectation big!”, Or a red bird effect design different from the effect design at the time of losing is displayed. On the other hand, if the result of determining whether or not the jackpot is successful is not displayed, a character such as “Can you expect?” Or “I'm sorry!” Or a production pattern of a blue bird different from the hit time is displayed. I try to make it come off. In addition, selection of the notice display content displayed on the notice display unit 13 is performed using a game random number value to be described later.

  Next, the control process of the ball game machine 1 will be described. The random number counter provided on the main control board 200 includes a jackpot determination 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 counter, and the like. .

  The big hit determination random number counter is used for the big hit determination in the big hit determination unit, and is composed of random numbers from “0” to “629”. The jackpot determination random number value in the jackpot determination random number counter is incremented by 1 every time a normal symbol / special symbol main random number update process described later starts from “0” when the gaming machine is turned on, and then reaches “629”. Is set to “0” and the addition is repeated again. The jackpot determination random number value is acquired due to winning at the start winning opening 42 (establishment of the determination condition), and the acquired value is set as a jackpot value when the low probability state is “3”, “397”. If it matches any of the above, it will be a big hit, while in the high probability state, '3', '53', '113', '173', '227', '281', '337' set as the numerical value of the big hit , '397', '449', '503' is a big hit.

  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 result of the determination is successful, and is composed of random numbers from “0” to “7”. . The jackpot symbol random number value starts from “0” when the power is turned on, and is incremented by 1 every update of the normal symbol / special symbol main random number, which will be described later. The addition is repeated. The jackpot symbol random number is acquired due to winning at the start winning opening 42 (satisfaction of the determination condition). The jackpot symbol random number is assigned a jackpot symbol combination that is stopped and displayed on the special symbol display unit when the jackpot winning / failing determination result is a hit. In the present embodiment, when the value is “0”, the first tick of the jackpot symbol combination is “1,1,1” (all symbols are the same), and when the value is “1”, “2,2,2”. 2 ticks, '2' means '3, 3, 3', 3 means '4, 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 to reach the reach state when the big hit determination result by the big hit determination random number value is out of order, and for determining whether or not to reach the reach state, from “0” to “126”. Consists of random numbers. 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 ball game machine 1 is turned on, and is incremented by 1 every time a normal symbol / special symbol main random number update process described below is performed. 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 (establishment of the determination condition), and when the determination result is wrong, the numerical value is compared with the predetermined reach establishment value. Presence or absence is determined. In this embodiment, the 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 that is to be stopped and displayed on the special symbol display unit 11 when the jackpot determination result based on the jackpot determination random number value is out of order. A special symbol data 1 random number counter for determining the left special symbol to be stopped and displayed on the symbol display unit 11, a special symbol data 2 random number counter for determining the middle special symbol, and a 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” when the power is turned on and is incremented by “1” every time the normal symbol / special symbol main random number update process described later is performed. The above addition is repeated again. The random number of the special symbol data 2 starts from “0” when the power is turned on, and is incremented by “1” when the random number of the special symbol data 1 is rewritten to “0”, and reaches “7”. 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, and is incremented by “1” when the random number of the special symbol data 2 is rewritten to “0”, and reaches “7”. 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 (satisfaction of the determination condition), and the special symbol data 1 to 3 is obtained by combining the random numbers of the special symbol data 1 to 3 when the special symbol data is lost. A judgment symbol consisting of a left special symbol, a middle special symbol, and a right special symbol displayed on the symbol display unit 42 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 production random number value starts from “0” when the ball game machine 1 is turned on, and is incremented by 1 every time a normal symbol / special symbol main random number update process described later is performed. Thus, the addition is repeated again. The effect random number value is acquired due to winning at the start winning opening 42 (satisfaction of the determination condition).

  As shown in Tables 3 and 4, 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.

  Regarding the acquired jackpot determination random number value, jackpot symbol random number value, reach random number value, special symbol data random number value, production random number value, a maximum of four each, the number of reserved balls in the corresponding area in the RAM of the main control board 200 Are stored in correspondence with each other and used sequentially.

The normal symbol random number counter is used to determine the small hits. When the ball game machine 1 is turned on, it starts from “0” and is incremented by “1” every time a normal symbol / special symbol main random number update process described later is started. , '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. Up to four normal symbols in the RAM of the main control board 200 are obtained. It is stored in the random value 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 CPU performs a main process M in accordance with each program stored in the ROM. FIG. 4 is a flowchart of the main process M.

  In the main process M, an initial setting process (S10), an interrupt prohibition process (S20), a normal symbol / special symbol main random number update process (S30), an interrupt permission process (S40), and an interrupt process (S100) are performed.

  In the initial setting process (S10), stack setting, interrupt time setting, CPU setting, SIO, PIO, CTC setting and the like are performed. This main process M is repeatedly performed at every interruption time, but the initial setting process (S10) is a process necessary only when the power is turned on, and is executed only in the first round, and is not executed thereafter. Details are omitted because they are well known. In the interrupt prohibition process (S20), even if the interrupt process (S100) is entered every 4 msec, the interrupt is prohibited until the interrupt is permitted. In the normal symbol / special symbol main random number update process (S30), various random numbers are added by 1 for each normal symbol / special symbol main random number update process (S30), and when the set upper limit value of each random number is reached as described above, Return to '0' and the addition is performed again. The updated random number is stored in the RAM of the main control board 200. In the interrupt permission process (S40), the interrupt process (S100) that enters every 4 msec is permitted.

  In the interrupt process (S100), as shown in FIG. 5, first, an output process (S110) is 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 hole) detected in the ball game machine 1 are detected. In the next normal symbol / special symbol main random number update process (S130), the same process as the normal symbol / special symbol main random number update process (S30) performed in the loop process in the main process M is performed. .

  In the start winning opening switch detection process (S140), as shown in FIG. 6, first, whether or not a game ball has won the start winning opening 42 (whether or not a determination condition is satisfied), that is, the start winning opening 42 is set. It is determined whether or not a game ball has been entered and 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 detection process is performed. (S140) is ended. On the other hand, when the winning winning opening 42 is won (the determination condition is satisfied), the update switching control signal is set in the output buffer (S140-2). The update switching control signal is transmitted to the sub-control board 205 in the output process (S110). In the present invention, the update switching control signal corresponds to a control signal (command) related to a ball that is transmitted to the slave control means due to the game ball having entered the winning opening. The update switching control signal may be transmitted to the sub-control board (secondary control means) 205 only when the number of reserved balls is less than four. Next, it is confirmed whether the number of reserved balls for special symbols (the number of times the determination condition is satisfied) stored in the RAM of the main control board 200 is 4 or more (S140-3). If the number of reserved balls for special symbols (the number of times the determination condition is satisfied) is 4 or more, the start winning opening switch detection process (S140) is terminated. The game ball detection number 1 detected by the start winning a prize switch is added to the number (the number of times the determination condition is satisfied) (S140-4). 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 (S140-5), a special symbol-related updated random number stored in the RAM is acquired, and the acquired random number is saved in the RAM address corresponding to the current number of reserved balls for special symbols ( Remembered). The random number values acquired here are a jackpot determination random number value, a jackpot symbol random number value, a reach random number value, a special symbol data random number 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 reserved symbols for special symbols (the number of times the determination condition is satisfied), for example, the current number of reserved balls for special symbols (the number of times the determination condition is satisfied) In the case of 1, the acquired random number value is saved in the RAM address corresponding to the number of reserved balls for special symbol (the number of times the determination condition is satisfied), and when the number of reserved balls for special symbol (the number of times the determination condition is satisfied) is 2. Means that the acquired random number value is saved in the RAM address corresponding to the number of reserved balls for special symbols (number of times the determination condition is satisfied) 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. 7, first, a special out symbol creation process (S160-1) is performed. In the special off symbol creation process (S160-1), as shown in FIG. 8, 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 symbols assigned to the random values of the special symbol data 1 to 3 (special symbols shown in Table 3). ) Is transferred to the data storage destination of the specially-offset symbols and stored as specially-offset symbols 1 to 3 to update the specially-offset symbol data (S160-1-5), and then this specially-offset symbol creation process (S160-1) ends. 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. 7, in the special operation process (S160), it is determined whether the special operation status is 1 to 4 after the special out symbol creation process (S160-1) (S160-2 to 160). -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 standby process (S160-5), as shown in FIG. 9, it is determined whether or not the number of reserved balls for special symbols (the number of times the determination condition is satisfied) is 0 (S160-5-1). When the number of reserved balls for use (the number of times the determination condition is satisfied) is 0, it is determined whether or not the special symbol display unit 11 is on a standby screen where the special symbol is not changing (S160-5-7). If this is the case, the special symbol standby process (S160-5) ends, while if it is not in the standby screen, the special symbol display unit 11 is set to a standby screen (S160-5-8). After that, the special symbol standby process (S160-5) ends.

  On the other hand, when it is determined in S160-5-1 that the number of reserved balls for special symbols (the number of times the determination condition is satisfied) is not 0, special symbol jackpot determination processing (S160-5-2) is performed. . In the special symbol jackpot determination process (S160-5-2), as shown in FIG. 10, first, the updated jackpot determination random number value stored in the RAM of the main control board 200 is loaded as a determination value (160). Along with -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 determination random number (S160-5-2-4), If the probability is not changing, that is, in the low probability state, it is determined whether or not the jackpot is based on whether or not the jackpot value in the low probability state matches the loaded jackpot determination random value (S160-5-2-5). If they coincide with each other, it is determined that the game is a jackpot, and the jackpot 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. 11, 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. 12, first, it is confirmed whether or not the big hit 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 3 and 4, 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 205 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 reserved symbol number for special symbols (the number of times the determination condition is satisfied) in the RAM, it is stored in the storage area of the address with the highest load (read) order. The stored data of the number of reserved symbols for special symbols (the number of times the determination condition is satisfied) is stored in the second and subsequent addresses because the seat is loaded and vacant by the previous process. With respect to the data of the number of special symbol reserved balls (the number of times the determination condition is satisfied), the address is shifted up by one. Specifically, as shown in FIG. 13, first, 1 is subtracted from the number of reserved symbols for special symbols (the number of times the determination condition is satisfied) stored in the RAM of the main control board 200 (for example, the number of reserved balls is 2). 1 is set to 1, 3 is set to 2, etc.) (S160-5-5-1), and the data corresponding to each number of held balls is the number of held balls obtained by subtracting 1 from each number of held balls. It is shifted to the RAM address (S160-5-5-2), and then corresponds to the highest number of reserved symbols for the special symbol (the number of times the judgment condition is satisfied) (the last load order is the fourth in this embodiment). The RAM address is set to 0 (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. Note that the variation of the special symbol (determination symbol) in the special symbol display unit 11 is transmitted from the main control board 200 as a command (control signal) including a jackpot determination result and a variation pattern command (control signal). Is set to start due to being received by the sub-control board 205.

  In the special symbol variation process (S160-6) performed when the special operation status is 2, as shown in FIG. 14, it is first determined whether or not the special symbol variation time has ended (S160-6-1). If the variation time has not ended, the special symbol variation process (S160-6) is terminated. On the other hand, if the variation time is over, a variation stop symbol table is set (S160-6-2) and variation stop symbol data is stored (SS160-6-3), followed by a special operation status. Is set to 3 (S160-6-4), and after other necessary processing (S160-6-5) is performed, the special symbol variation processing (S160-6) is completed.

  In the special symbol determination process (S160-7) performed when the special operation status is 3, as shown in FIG. 15, it is first determined whether or not the big hit flag is ON, that is, whether or not the big hit flag (S160-7-). 1). When the jackpot flag is ON, that is, when the jackpot is big, the round counter is set (S160-7-2), the special operation status is set to 4 (S160-7-3), and this special symbol confirmation processing (S160). -7) ends. On the other hand, if the jackpot flag is OFF, that is, it is off, the special operation status is set to 1 (S160-7-4), and then the special symbol confirmation process (S160-7) ends.

  In the special electric accessory processing (S160-8) performed when the special operation status is 4, as shown in FIGS. 16 and 17, first, the probability variation flag is reset to OFF (S160-8-1). Then, it is determined whether or not the jackpot end flag is ON (the jackpot game end) (S160-8-2). When the jackpot end flag is not ON, that is, when the jackpot game is not ended, it is determined whether or not the big prize opening 15 is currently open (S160-8-3). It is determined whether or not it is the opening time of the big prize opening 15 (SS160-8-4). In the case of the opening time of the special winning opening 15, the opening process of the special winning opening is performed (S160-8-5), and then the special electric accessory processing (S160-8) is finished. On the other hand, when it is not the opening time of the special winning opening 15, this special electric accessory processing (S160-8) ends.

  On the other hand, if it is determined in S160-8-3 that the big prize opening 15 is open, ten game balls are won in the big prize opening 15 (S160-8-6) or the round end time (in this embodiment). 30 seconds) is determined (S160-8-7), and if it is none, the special electric accessory processing (S160-8) is terminated as it is, and a special prize opening is received. In the case where 10 game balls are won in 15 or the end of the round end time has elapsed, the special winning opening closing process (S160-8-8) and the process of subtracting 1 from the value of the round counter (S160-8-) 9) is performed. In the special winning opening closing process (S160-8-8), a special winning opening closing command is set in the output buffer. Subsequently, it is determined whether or not the round counter is 0 (S160-8-10). If the round counter is not 0, the special electric accessory processing (S160-8) is finished as it is, and the round counter is processed. When the counter is 0, a jackpot end process (S160-8-11) is performed, and the jackpot random number data stored in the special symbol reserved ball number storage area of the RAM is stored together with the jackpot end command together with the sub-control. It is set in the output buffer so as to be transmitted to the substrate 205. Thereafter, the jackpot end flag is turned ON (S160-8-12), and the special electric accessory processing (S160-8) is ended.

  On the other hand, when it is determined in S160-8-2 that the jackpot end flag is ON, that is, when the jackpot end flag is determined, the process of setting the jackpot end flag to OFF (S160-8-13) and the process of turning the jackpot flag off. (S160-8-14) is performed, and then it is determined whether the stop symbol is a probabilistic symbol (an odd number in the present embodiment) (S160-8-15). In the case of the probability variation symbol, the probability variation flag is turned ON (S160-8-16) and the special operation status is set to 1 (S160-8-17), while the probability variation symbol is different from the probability variation symbol. Jumps the process (S160-8-16) for turning on the probability variation flag, and the special operation status is set to 1 (S160-8-17). Thereafter, the special electric accessory processing (S160-8) is completed. In addition, the process in said S160-8-15 is corresponded to the privilege game determination means in this invention.

  In the reserved ball number processing (S170), as shown in FIG. 18, the reserved ball number is loaded (S170-1), and the reserved ball number is set in the output buffer (S170-2).

  In the other processing (S180), various other processing necessary for the game is performed, but description of processing that is not particularly relevant in the present invention is omitted.

  In the sub-process J performed by the sub-control board (sub-control circuit) 205, as shown in FIG. 19, the CPU initialization process is performed in the sub-control board 205 when the ball game machine 1 is turned on (S201). In the CPU initialization process (S201), stack setting, CPU setting, SIO, CTC setting, and the like are performed. Next, it is determined whether the power-off signal is ON and the RAM contents are normal (S202). If the power-off signal is ON and the content of the RAM is normal, it is determined whether the random number acquisition flag provided on the sub control board 205 is ON (S204). Otherwise, the initialization of the RAM (S203) is performed. After the determination, it is determined whether the random number acquisition flag is ON (S204).

  If the random number acquisition flag is OFF, a calculation random number value update process (S205) is performed next. On the other hand, if the random number acquisition flag is ON, a calculation random number value update process (S205) is performed. Instead, the loop process is repeated, resulting in an infinite loop-like standby state. The random number acquisition flag is set to OFF when the power is turned on, and is set to ON or OFF in a 10 ms timer interrupt process (S500) described later. The calculation random number update process (S205) corresponds to the process of the random number update means for updating the calculation random value in the present invention.

  In the calculation random number value update process (S205), a calculation random number counter update process (1 addition) is performed in the calculation random number counter provided in the sub-control board 205. The calculation random number value is composed of numerical values from “0” to “65535”. When reaching “65535” by the update process (1 addition), it returns to “0” and the update process (1 addition) is performed again. As described above, when the random number acquisition flag is ON, the calculation random number value is not updated, is maintained in a state stopped at the previous update value, and when the random number acquisition flag is OFF, from the previous update value Update starts. The process when the random number acquisition flag is ON corresponds to a random number update stop process according to the present invention, while the process when the random number acquisition flag is OFF corresponds to a random number update stop cancellation process according to the present invention.

  After the calculation random number update process (S205), a loop process is performed. During this loop process, an INT interrupt process (S300) is received when a command (control signal) is received from the main control board 200. In addition, 2 ms timer interrupt processing (S400) is performed every 2 ms, and 10 ms timer interrupt processing (S500) is performed every 10 ms.

  In the INT interrupt processing (S300), the strobe signal from the main control board 200 is input to the INT input section of the CPU in the sub control board 205, and if the strobe signal is input, the INT interrupt is forced. Processing (S300) is executed. The INT interrupt process (S300) is a hardware-structured interrupt process, and is executed with priority over the 2 ms timer interrupt process (S400) and the 10 ms timer interrupt process (S500). Note that the sub control board 205 is designed to start up earlier than the main control board 200 when the power is turned on or reset. During the CPU initialization process (S201) of the sub control board 205, etc. In addition, the INT interrupt processing (S300) is not performed.

  In the INT interrupt process (S300), as shown in FIG. 20, it is confirmed whether the strobe (STB) signal is ON (S301). When the strobe signal is ON, that is, when the strobe signal is input to the INT input unit, The command (control signal) output from the main control board 200 is received and stored in the RAM (S302). Here, the command (control signal) received from the main control board 200 includes a variation pattern, jackpot symbol data, jackpot determination data, missed symbol data, an update switching control signal, and the like. It should be noted that the variation time set in advance in the variation pattern is set in the process described later. On the other hand, if the strobe signal is not ON, the INT interrupt processing (S300) is completed at that time.

  The 2 ms timer interrupt process (S400) is a process performed every 2 ms, and is executed with priority over the 10 ms interrupt process, and the 10 ms interrupt process (S500) is not executed during the execution of the 2 ms interrupt process (S400). It has become. In the 2 ms timer interrupt process (S400), a ramp data output process (S401) is executed as shown in FIG.

  In the lamp data output process (S401), the lamp data set in the 10 ms interrupt process (S500) described later is output to the decoration lamp 35.

  The 10 ms timer interrupt process (S400) is an interrupt process performed every 10 ms. As shown in FIG. 22, the command monitoring process (S501), the ramp process (S502), and the command transmission process (S503) are performed in order.

  In the command monitoring process (S501), as shown in FIG. 23, first, the analysis process of the command (control signal) received in the INT interrupt process (S300) and the storage of the command (control signal) to other control boards, Other operations are set (S501-1).

  Next, it is determined whether the command (control signal) received from the main control board 200 is an update switching control signal (S501-2). If it is an update switching control signal, a calculation random number update switching process (S501-3) is performed. Done.

  In the calculation random number update switching process (S501-3), as shown in FIG. 24, it is determined whether the random number acquisition flag is ON (S501-3-1). When it is determined that the random number acquisition flag is not ON, that is, OFF, a calculation random number value is acquired, a game random number value is calculated using the acquired calculation random number value, and a game random value is stored. (S501-3-2). Thereafter, the random number acquisition flag is set to ON (S501-3-3). S501-3-2 corresponds to a random value calculation means in the present invention.

In the present embodiment, the calculation of the game random number value by the random value calculation means in S501-3-2 is performed by the first calculation process and the second calculation process. The first calculation process is a calculation process for obtaining a numerical value during calculation using the acquired calculation random number value, and is a process of multiplying the acquired calculation random value by a fixed value and adding the fixed value.
-Numerical value during calculation = (random number for acquisition calculation) x A + B
Assuming that A is 12345, B is 12345, and the obtained random number for calculation is 100, the numerical value during calculation is 100 × 12345 + 12345 = 1246845.
Further, instead of the constant value A, the value A ′ of the variation time (seconds) of the variation pattern transmitted from the main control board 200 is used, and a numerical value during calculation = (random number value for acquisition calculation) × A ′ + B, It is good. For example, assuming that A ′ is a value 65000 ms of the fluctuation time 65000 ms in the hit fluctuation pattern 1 of Table 3, B is 12345, and the obtained random number for calculation is 100, the numerical value during calculation is 100 × 65000 + 12345 = 65112345.

The second calculation process is a calculation process for obtaining a game random number value using a calculation halfway value, and a remainder obtained by dividing the calculation halfway value by the number C of game random values is used as a game random number value. . The number C of game random numbers in this embodiment is 11. For example, when the numerical value during calculation is 1246845, the game random number value is calculated as follows, and the remainder 6 becomes the game random number value.
1246845/11 = 11349 remainder 6
In addition, when the calculation intermediate numerical value 651345 obtained by setting A ′ as the value 65000 of the variation time 65000 ms in the variation pattern 1 is used, the game random number value is calculated as follows, and the remainder 4 becomes the game random number value. .
6512345/11 = 592031 remainder 4

  On the other hand, when the random number acquisition flag is determined to be ON in S501-3-1, the game random number value is obtained by the third calculation process and the fourth calculation process using the previously calculated random number value or the previous calculation intermediate value. It is calculated (S501-3-4), and then the random number acquisition flag is set to OFF (S501-3-5). S501-3-4 corresponds to the random value calculation means in the present invention.

The third calculation process is a calculation process for obtaining an intermediate calculation value using the previous calculation random number value or the previous calculation intermediate value, and multiplying the previous calculation random value or the previous calculation intermediate value by a certain value. The process is to add a certain number.
-Numerical value during calculation = (Random value for calculation acquired last time or numerical value during previous calculation) x D + E
D and E may be the same value as or different from A and B in the first calculation process. For example, when the previous calculation intermediate value 1246845 is used and D is A value 12345 and E is B value 12345, the current calculation intermediate value is 1246845 × 12345 + 12345 = 1539923870.

  Furthermore, D may be a value of the variation time (seconds) of the variation pattern transmitted from the main control board 200. For example, when D is the value 65000 ms of the variation time 65000 ms in the hit variation pattern 1, E is the value 12345 of B, and the previous calculation intermediate value 6512345 (value obtained using the variation time 65000 of the variation pattern 1) is used, The numerical value during calculation this time is 651345 × 65000 + 12345 = 42333024337345. Further, for example, when the previously obtained random number value for calculation 100 is used, D is a value 18000 ms for the fluctuation time 18000 in the hit fluctuation pattern 2, and E is a value 12345 for B, the numerical value during this calculation is 100 × 18000 + 12345 = 181345. As described above, when the value of the variation time (seconds) of the variation pattern transmitted from the main control board 200 is set to the value D, even if the previously obtained random number for calculation is used, the calculated intermediate numerical value is obtained. Can be changed according to the selected variation pattern, and it is possible to prevent the bias of the random number for gaming.

The fourth arithmetic process is an arithmetic process for obtaining a game random number value using a numerical value during calculation, and is the same process as the second arithmetic process. That is, the remainder obtained by dividing the mid-calculation value obtained in the third calculation process by the number C of game random numbers is used as the game random number. The number C of game random numbers in this embodiment is 11. For example, in the third calculation process, when the previous calculation intermediate value 1246845 is used, D is A value 12345, and E is B value 12345, and the current calculation intermediate value is 15392313870, the game random number value is as follows: The remainder 10 is the game random value.
15392313870/11 = 1399301260 remainder 10
On the other hand, D is the value 65000 of the fluctuation time 65000 ms in the hit fluctuation pattern 1, E is the B value 12345, and the previous calculation intermediate value 651123 in the third calculation process (the calculation obtained using the fluctuation time 65000 of the fluctuation pattern 1) If the current calculation intermediate value obtained using (intermediate numerical value) is 4233024373345, the game random number value is calculated as follows, and the remainder 7 becomes the game random number value.
423302437345/11 = 38482039758 remainder 7
Further, D is a value 18000 of a fluctuation time 18000 ms in the hit fluctuation pattern 2, E is a value 12345 of B, and the current calculation intermediate value obtained by using the previously acquired random number value 100 in the third calculation process is 1812345. In this case, the game random number value is calculated as follows, and the remainder 7 becomes the game random number value.
1812345/11 = 164758 remainder 7

  If it is determined in S501-2 that the command received from the main control board 200 is not an update switching control signal, it is next determined whether the command is related to a variation pattern (S501-4). In the case of a command related to a variation pattern, it is determined whether it is a winning variation pattern (S501-5). In the case of a winning variation pattern, S501-3-2 or S501-3 in the calculation random number update switching processing (S501-3). The notice display contents are selected from the jackpot selection table of Table 1 based on the game random number value calculated in -4, and each command such as the variation time is set from the variation pattern in the first variation pattern table of Table 3. (S501-6).

  On the other hand, if it is determined in S501-5 that it is not a hit fluctuation pattern, that is, a deviation fluctuation pattern, it is calculated in S501-3-2 or S501-3-4 in the calculation random number update switching process (S501-3). The notice display contents are selected from the deviation selection table of Table 2 based on the game random number value, and each command such as the variation time is set from the variation pattern in the second variation pattern table of Table 4 (S501-). 7).

  On the other hand, if it is determined in S501-4 that the command is not related to the variation pattern, processing corresponding to each command is executed (S501-8).

  In the lamp processing (S502), lamp data relating to the control of the decorative lamp 35 is set. In the next command transmission process (S503), each command is transmitted to the corresponding device. For example, according to a command transmitted to the display control board 210, the special symbol display unit 11 displays a variation of the special symbol (determination symbol) and a determination result of whether or not the change is due to the stoppage of the variation, or the advance notice display unit 13 notifies the advance. Display is performed and sound is generated from the speaker 38.

  As described above, in the above-described embodiment, the update of the random number for calculation is stopped by the game ball entering the first start winning port (winning port) 42 after the power is turned on, and then the starting winning port (winning port) ) The random number value for calculation is alternately canceled and renewal stopped by entering the ball 42, and the random number value for the game is calculated due to the game ball entering the start winning port (winning port) 42) Is done. Therefore, when the calculation random number value is in the update stop state, the calculation random number value update stop is canceled based on a random occurrence that a game ball enters the start winning opening (winning port) 42, and the game Since the calculation random number value that is the basis of the calculation of the random number value is newly acquired, the calculation random number value that is the basis of the calculation of the game random number value can be made different at a random opportunity and calculated. It is possible to prevent the bias of the game random value, prevent the bias of the content in the notice display using the game random value, improve the performance of the game, and prevent the game from becoming monotonous.

  In the above-described embodiment, the predetermined opportunity for obtaining the random number for calculation is that the game ball first enters the start winning port (winning port) 42 after the gaming machine 1 is turned on (first determination condition) After that, when the game ball enters the start winning port (winning port) 42 in the renewal stop state (judgment condition is satisfied).

  Further, in the above-described embodiment, the calculation random number value is canceled and the update stop is switched by the game ball entering the start winning opening (winning port) 42. However, the calculation random number value is acquired. The update stop switching random number value is created based on the update random number value for calculation when the update stop switching random number value is the stop random value, while the update stop processing of the calculation random number value is performed. If it has been executed, an update stop switching random number value is generated due to the game ball entering the start winning opening (winning opening) 42, and the generated update stop switching random number value is the stop release random number value. At the same time, the calculation random number value update stop cancellation process may be performed, and the game random number value may be calculated due to the game ball entering the start winning opening (winning port) 42. .

  FIG. 25 shows a flow of an example in which the update stop switching random number value is used in the calculation random number update switching process (S501-3). Processing other than the calculation random number update switching processing (S501-3) is the same as the processing in FIGS.

  In the calculation random number update switching process shown in FIG. 25, it is determined whether the random number acquisition flag is ON (S501-3-1A). The random number acquisition flag is set to OFF when the gaming machine 1 is turned on. When it is determined that the random number acquisition flag is not ON, that is, OFF, a random number value for calculation is acquired, a random number value for game is calculated and stored (S501-3-2A), and then an update stop switching random number value Is created (S501-3-3A). The processing of S501-3-3A corresponds to the processing of the update stop switching random value generation means in the present invention.

  The calculation of the game random number value in S501-3-2A is performed by the first calculation process and the second calculation process described in S501-3-2. Details are omitted because they overlap with S501-3-2.

In the present embodiment, the update stop switching random number value in S501-3-3A is created in the present embodiment in the current calculation halfway value (obtained in the first calculation process) used for calculating the game random number value in S501-3-2A. The remainder obtained by dividing (value) by 2 is the update stop switching random number value.
・ (Numerical value during calculation) / 2 = quotient, remainder (= update stop switching random value)
For example, if A is 12345, B is 12345, and the calculated intermediate value 1246845 is 100, 1246845/2 = 623422, the remainder is 1, and the remainder 1 is the update stop switching random number value. It is.
Further, when using the calculation intermediate value 651345 when the value 6 ′ of the fluctuation time 6500 ms of the hit fluctuation pattern 1 transmitted from the main control board 200 is the value A ′, B is 12345, and the obtained random number for calculation is 100, 6512345/2 = 3256172, the remainder is 1, and the remainder 1 is the update stop switching random number value.

  Next, it is determined whether the update stop switching random number value created in S501-3-3A is a stop random number value (S501-3-4A). The stop random number value is set to ‘1’, and the stop release random number value is set to ‘0’. When the generated update stop switching random number value is a stop random number value, the random number acquisition flag is turned on, while when the update stop switching random number value is different from the stop random number value, that is, in the case of a stop release random number value The random number acquisition flag is kept OFF (S501-3-5A).

  On the other hand, when the random number acquisition flag is determined to be ON in S501-3-1A, the game random number value is calculated and stored based on the previously acquired random number value for calculation or the numerical value during calculation (S501-3-6A). Then, an update stop switching random number value is created (S501-3-7A). The processing of S501-3-7A corresponds to the processing of the update stop switching random value generation means in the present invention.

  The calculation of the game random number value in S501-3-6A is performed by the third calculation process and the fourth calculation process described in S501-3-4. Details are the same as S501-3-4, and will be omitted.

In the present embodiment, the update stop switching random number value in S501-3-7A is generated by dividing the previous intermediate calculation value used for calculating the game random number value in S501-3-6A by 2. Is the update stop switching random value.
・ (Numerical value during calculation) / 2 = quotient, remainder (= update stop switching random value)
For example, if the previous halfway numerical value used in S501-3-7A is 1246845, 1246845/2 = 623422, the remainder is 1, and the remainder 1 is the update stop switching random number value.
When the previous calculation halfway value used in S501-3-7A is 181345, 182345/2 = 906172, the remainder is 1, and the remainder 1 is the update stop switching random number value.

  Next, it is determined whether the update stop switching random number value created in S501-3-7A is a stop cancellation random value (S501-3-8A). The stop release random number value is set to ‘0’, and the stop random number value is set to ‘1’. If the generated update stop switching random number value is a stop release random number value, the random number acquisition flag is turned OFF, while if the update stop switching random number value is different from the stop release random number value, that is, the stop random number value In this case, the random number acquisition flag is kept ON (S501-3-9A).

  By using the update stop switching random number value as described above to stop the update of the calculation random number value and cancel the update stop, the bias of the game random number value calculated using the acquisition calculation random value can be more reliably determined. Can be prevented. Therefore, it is possible to effectively prevent content bias in the notice display using the game random number value, and to prevent the game from being monotonous and to further improve the performance. Also, the calculation random number value is larger than the game random value (numerical value range), and the calculation random number value is acquired with the same value in a short cycle or selected for a short cycle. It is configured to prevent occurrence of regularity in numerical values.

  In the example using the update stop switching random number value described above, the predetermined opportunity for obtaining the calculation random number value is that the game ball is first loaded into the start winning port (winning port) 42 after the gaming machine 1 is powered on. When the ball enters (the first determination condition is satisfied), and thereafter enters the start winning port (winning port) 42 in the update stop state (the determination condition is satisfied), and the update switching random number value becomes the stop release random value. It is time to become.

  The present invention is not limited to the embodiments described above, and can be modified without departing from the spirit of the invention. For example, in the above embodiment, the slave control means (sub control board) is the lamp control board, but another control board may be used. Further, the arithmetic processing for calculating the game random number value is not limited to the above embodiment. Further, the generation of the update stop switching random number value is not limited to the calculation using the mid-calculation numerical value obtained when the game random number value is calculated, and may be generated by another method. Furthermore, the use of the game random number is not limited to the selection of the notice display content, but may be used for other effects.
