In the case of a normal jackpot that is not a probable change, the probability of a jackpot is set to the low probability state (normal state) after the special game (a jackpot game) is finished until the jackpot is determined to be a jackpot by the next jackpot determination. In the present embodiment, when the determination result is a jackpot and the jackpot symbol random number is any odd number of '1', '3', '5', '7', '9', that is, the display device The combinations of jackpot symbols that are stopped and displayed at 10 are “1, 1, 1”, “3, 3, 3”, “5, 5, 5”, “7, 7, 7”, “9, 9, 9”. A high probability state (probability variation state) is obtained in the case of any odd combination (odd tick). In the present embodiment, the high probability state (the probability variation state is set to satisfy the specific condition.
On the other hand, when the determination result is a big hit and the big hit symbol random number is any one of “0”, “2”, “4”, “6”, “8”, that is, the display device 10 stops. The displayed jackpot symbol combination is “0, 0, 0”, “2, 2, 2”, “4, 4, 4”, “6, 6, 6”, or “8, 8, 8” In the case of an even number of combinations (even numbers), a low probability state (normal state) is obtained.

  Further, when the probability variation (high probability) state is reached, the jackpot probability in the determination of success or failure becomes the high probability (probability variation) state, and the opening (expansion) time of the lower start winning opening 42 is low probability (normal). The number of times of opening (expanding) of the lower start winning opening 42 is increased from 1 to 3 times in the low probability (normal) state, and the probability per normal symbol is increased. It increases from 1/300 to 1/5 of the low probability (normal) state.

  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 random number of the reach random number counter (reach random number) starts from “0” when the gaming 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. Then, it is set to “0” and the addition is repeated again. The reach random number is acquired due to winning in the upper start winning opening 41 or the lower start winning opening 42, and when the result of the determination is wrong, the numerical value is compared with a predetermined reach establishment value. The reach is determined. 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 that is to be stopped and displayed on the display device 10 when the jackpot determination result based on the jackpot random number value is out of order. A random number counter for special symbol data 1 for determining the left special symbol to be stopped, a random number counter for special symbol data 2 for determining the middle special symbol, and a random number counter for 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 “9”.

  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. And the 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 “9”. Then, it is rewritten to “0” and the addition is repeated again. Further, 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 “9”. 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 random number of the special symbol data 1 to 3 is “0” for “0”, “1” for “1”, “2” for “2”, etc. Identification information consisting of a left special symbol, a middle special symbol, and a right special symbol, which are stopped and displayed on the display device 10 when they are off, is assigned. The random numbers of the special symbol data 1 to 3 are acquired due to winning in the upper starting winning port 41 or the lower starting winning port 42, and when the special symbol data 1 to 3 are combined, Identification information including a left special symbol, a middle special symbol, and a right special symbol displayed on the display device 10 is determined.

  The variation pattern random number counter is used when a variation pattern of a special symbol (determination symbol) in the display device 10 is selected from the variation pattern table, and includes variation pattern random numbers from ‘0’ to ‘198’. The random number value of the fluctuation pattern starts from “0” when the gaming machine 1 is turned on, and is incremented by 1 for each of the normal symbol / special symbol main random number update processing to be described later. It is set to “0” and the addition is repeated again. The fluctuation pattern random number value is acquired due to winning in the upper starting winning opening 41 or the lower starting winning opening 42.

  A plurality of variation pattern tables are provided. In this embodiment, there are provided four types of variation pattern tables including a first variation pattern table, a second variation pattern table, a third variation pattern table, and a fourth variation pattern table. Each variation pattern table includes a plurality of variation patterns to be displayed on the display device 10 and is stored in the ROM of the main control board 200. In the present embodiment, the variation pattern is selected from the variation pattern table selected according to whether the gaming state is the probability variation state or the normal state, and whether the determination result is a hit or wrong. One variation pattern is selected based on the pattern random value. A variation pattern random value is assigned to each variation pattern, and a variation pattern corresponding to the acquired variation pattern random value is selected. A variation time is set for each variation pattern, and the display mode (including the variation time of the special symbol) of the special symbol to be displayed on the display device 10 is determined according to the set variation time. It is configured.

  The acquired jackpot random number value, jackpot symbol random number value, reach random number value, and variation pattern random number value are stored in correspondence with the number of reserved balls in a corresponding area in the RAM of the main control board 200, respectively. Used sequentially.

  The normal symbol random number counter is used for determination per ordinary symbol, has a normal symbol random number of “0” to “299”, and starts from “0” when the gaming machine 1 is turned on. “1” is added for each normal symbol / special symbol main random number update process, and when it reaches “299”, it is rewritten to “0” and the addition is repeated again. The normal symbol random numbers are acquired every time the normal symbol variation start switch detects a game ball that has passed through the normal symbol variation start gate 55, and up to four normal symbol random numbers in the RAM of the main control board 200. Stored in the storage area. The value of the normal symbol random number acquired due to the passing of the game ball through the normal symbol variation start gate 55 is set to “5” (1/300) as the established value per normal symbol in the low probability state. If it matches the probability of “0” to “59” (1/5) set as a numerical value established per normal symbol in the probability variation (high probability) state, Usually per symbol. In the case of per normal symbol, “O” is displayed on the normal symbol display device 50, and the lower start winning opening 42 is released according to whether or not it is in the certain change state, and the release time is released. If the normal symbol random number value does not match the established value per normal symbol, it is out of the normal symbol and "x" is displayed on the normal symbol display device 50, and the lower start winning opening 42 is in a state where it is difficult to win. Leave.

As the random number counter provided on the sub-control board 205, there are a notice selection random number counter and a divided random number counter.
The notice selection random number counter is used when selecting the type of notice effect to be displayed during the special symbol variation display on the display device 10, and includes a notice selection random number of “0” to “99”. This notice selection random number, which starts from “0” when the gaming machine 1 is turned on, is incremented by 1 every random number seed update process in the sub-control main process described later, and reaches “99” when reaching “99”. It returns to repeat the addition again.

  The period of the effect displayed on the display device 10 is composed of the first to fourth divided periods at the maximum in this embodiment. As the types of notice effects, notices A to C are produced in the first divided period, notices D to F are produced in the second divided period, notices G to I are produced in the third divided period, and notices J to L are given in the fourth stage. The notice is provided, and one notice for each divided period is individually selected by the notice selection random number value. As shown in FIG. 4, the notice selection random number is assigned a notice effect in each divided period, and the notice can be selected based on the obtained notice selection random number value. In the present embodiment, the effect of the notice C in the first divided period is set to the sign notice effect corresponding to the special effect of the present invention. When the display device 10 displays the effects of the first divided period, the indication / notice effect is an effect of displaying a part of the contents of the effects performed after the second divided period in the order of the divided periods.

  The divided random number counter is used when determining the number of the divided periods when the notice C effect is selected as the effect of the first divided period. The divided random numbers of “0” to “9” are used. Is provided. This divided random number starts from “0” when the gaming machine 1 is turned on, and is incremented by 1 for each random number seed update process in the sub-control main process to be described later. It returns to repeat the addition again. Divided random numbers “0” to “3” are assigned 2 as the number of divided periods (that is, two of the first divided period and the second divided period), and divided random numbers “4” to “6” are divided. 3 is assigned as the number of periods (ie, three from the first divided period to the third divided period), and the divided random numbers '7' to '9' are assigned 4 as the number of divided periods (ie, the first divided period to the third divided period). 4 of 4 divided periods) are allocated, and the number of divided periods can be selected by the obtained divided random number value. In the present embodiment, when the combination of the stop special symbols is a reach non-established combination that does not go through the reach state, the number of divided periods is forcibly set to 2 (first divided period and second divided period). .

  The game of the gaming machine 1 will be briefly described. In the gaming machine 1, when the game balls launched by the launch device 64 toward the game area 6 win the various winning holes, a predetermined number of gaming balls corresponding to the winning holes are awarded as the winning balls from the payout device 281. The upper ball receiving tray 36 is paid out. Further, when the game ball passes through the normal symbol variation start gate 55, a normal symbol random number is acquired, and the normal symbol display device 50 determines the normal symbol per unit based on the acquired random number value. Starts to fluctuate and stops after fluctuating for a predetermined time. At that time, if the determination result per normal symbol is a win, it stops at the normal symbol, “◯” in this example, and the two movable pieces 42a and 42b of the lower start winning port 42 are on the back side. The closed solenoid (normal state), which is almost vertical and difficult to win, is changed from the closed solenoid (normal state) to the open state in which a winning is possible with a V shape (reverse C shape). In the case of the probability variation state, when it comes to the normal symbol, the lower start winning opening 42 is opened for 2 seconds three times. On the other hand, in the case of the low probability state, it is released for 1 second. Is performed once. When a game ball wins the lower start winning opening 42, a predetermined number of game balls are paid out as a prize ball.

  Further, when a game ball is won in the upper start winning opening 41 or the lower start winning opening 42, if the number of special symbol reserved balls is less than 4, the special symbol reserved ball number is incremented by 1 to obtain a jackpot random number value, jackpot Random values such as symbol random values, reach random values, and fluctuation pattern random values are acquired and stored in the RAM of the main control board 200 in the order of winning until the maximum is 4. And if the number of special symbol reservation balls memorize | stored in RAM of the said main control board 200 is one or more, while determining the success / failure of jackpot based on the previously acquired jackpot random value, One variation pattern is selected from the variation pattern table based on the pattern random value. Based on the selected variation pattern, the display device 10 starts the variation display of the special symbol. In this embodiment, the number of the special symbol holding balls is subtracted from the RAM of the main control board 200 by the start of the change of the special symbol, and the random number corresponding to the start of the change is deleted (erased) from the RAM of the main control board 200. ) If the number of special symbol reservation balls stored in the RAM of the main control board 200 is 0, then a game ball wins the upper start winning port 41 or the lower start winning port 42, and the main ball Until the number of special symbol reservation balls stored in the RAM of the control board 200 becomes 1 or more, the determination of whether or not the winning symbol is determined and the special symbol is not variably displayed.

  The special symbol is stopped and displayed on the display device 10 when the variation time set for the selected variation pattern elapses (end of the variation time). If the game success / failure determination result is out of place, the display device 10 stops the left special symbol, middle special symbol, and right special symbol when they are out of combination (in a state other than the slotted pattern) and becomes a special game (big hit game). There is no migration. If the number of special symbol reservation spheres stored in the RAM of the main control board 200 is 1 or more, the jackpot random number value is acquired again in the same manner as described above, and the jackpot random number value is obtained based on the acquired jackpot random number value. In addition to the determination of whether or not, a variation pattern is selected from the variation pattern table based on the determination result and the variation pattern random value, and the display device 10 includes a variation display of a special symbol based on the selected variation pattern. Production is performed.

  On the other hand, if the determination result is a jackpot, the left special symbol, the middle special symbol, and the right special symbol are stopped on the display device 10 in a jackpot symbol combination (in this embodiment, a bonito) and a special game (a jackpot game) ).

  In a special game (big win game) state, the open / close plate 46 of the big prize opening 45 is opened to make it easy to receive the game balls falling on the surface of the game area 6 so that the big prize opening 45 can be awarded, When there is a prize at the big prize opening 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, 15 seconds) or when the number of winning balls reaches a predetermined number (for example, 10), and the opening / closing plate 46 is repeatedly opened and closed for 15 rounds.

  In this embodiment, the display device 10 is specially combined with a normal jackpot symbol combination consisting of even numbers such as “0, 0, 0”, “2, 2, 2”, “4, 4, 4”. When the symbol is stopped and displayed, it is usually a big jackpot. After the special game (jackpot game) is finished, the jackpot probability is low (in this embodiment, (2/630 (1 / 315)) On the other hand, the display device 10 has a probability variation jackpot combination consisting of odd numbers such as “1, 1, 1”, “3, 3, 3”, “5, 5, 5”, etc. When the special symbol is stopped and displayed, it becomes a probable jackpot, and the probability of jackpot is high (in this example, (12/630 ( 6/315)) and the lower start winning opening 4 The opening (expansion) time of the engine is increased from 1 second in the low probability (normal) state to 2 seconds, and the number of opening (expansion) of the lower start winning opening 42 is one in the low probability (normal) state. And the probability per normal symbol increases from 1/300 to 1/5 of the low probability (normal) state.

  Further, in this embodiment, during the period from the start of the special symbol variation display to the stop display, the display device 10 displays an effect composed of a character image, a background image character, and the like along with the special symbol variation display. The production period is composed of the first to fourth division periods at the maximum as described above, and the production (notice) selected in each division period is displayed in the order of the division periods. Further, when the effect of the notice C is selected as the effect of the first divided period, a predictive notice effect corresponding to the special effect of the present invention is displayed. In the predictive notice effect, during the display of the effect in the first divided period, a part of the effect displayed after the second divided period is displayed in the order of the divided periods.

  In the present embodiment, the first divided period is the portion (5-1) from the start of the change of the special symbol to before reaching the reach state, and the second divided period is temporarily stopped when the special symbol is in the reach state or is not in the reach state. Part (5-4) where the special symbol stops, part (5-5) where the effect is executed immediately after the third divided period is reached, and the effect that the fourth divided period is displayed in the third divided period FIG. 5 shows an example of a sign / prediction effect when the number of divided periods is four. In the special effect (predictive notice effect), as shown in (5-1) to (5-3) of FIG. 5, the step shown in (5-1) in the effect of the notice C displayed in the first divided period. 1, a part of the effect to be displayed in the subsequent second divided period (5-4), in the example shown, a part of the effect indicating the reach state is displayed, and the following (5-2) In step 2 shown, a part of the effect to be displayed in the subsequent third divided period (5-5) is displayed, and in step 3 shown in (5-3), the subsequent fourth divided period A part of the effect to be displayed in (5-6) is displayed. In this way, in the production of the first divided period, it is possible to see a part of the production after the second divided period, so it is possible to improve interest in the production in the middle divided period and the final divided period. It becomes. In addition, a part of each effect displayed during the special effect is a display for informing the player in advance what kind of effect is executed in each divided period. It is preferable to display the part (part that the player wants to know), and in this embodiment, the second divided period is a part for determining whether or not the special symbol is in the reach state. The state in which the special symbol is temporarily stopped is displayed as to what kind of symbol is reached (5-1). Does the third division period continue to change the special symbol until the subsequent fourth division period? Since an effect indicating the degree of expectation is executed, the number of stars indicating the degree of expectation is displayed in step 2 (5-2). Since an effect of battle with the enemy is executed in the fourth divided period, in step 3 it is set to display the enemy to battle (5-3). Furthermore, in the special effect in the first divided period, a part of the contents of the effects displayed in the second divided period to the fourth divided period are displayed in order of the divided periods, and therefore displayed in stages. Therefore, it is possible to display without discomfort. The special symbol is variably displayed at a position 13 at the lower right of the display device 10.

  After the production of the first division period, as shown in (5-4) to (5-6) in FIG. 5, the division periods are divided into the second division period to the fourth division period in the order displayed during the special production. Is displayed, and the special symbol is stopped and displayed after the end of the fourth divided period. In the illustrated example, the special symbol variation display in the first, third, and fourth divided periods is displayed at the lower right position 13 of the display device 10. Furthermore, in this embodiment, when the combination of special symbols that are stopped and displayed on the display device 10 is a non-reachable combination that is stopped and displayed without reaching the reach state, an effect that is executed after the reach state is reached. Since it is not performed, the number of divided periods is forcibly set to two, so the number of notice effects displayed in the first divided period, that is, the number of partial displays after the second divided period is 3. In the above case, the degree of expectation to be stopped and displayed with the jackpot symbol combination becomes high, and it becomes possible to further improve the interest in the production.

The control process in the gaming machine 1 will be described below. Examples of main flags provided in the control circuit of the main control board 200 include a big hit flag, a big hit end flag, a probability change flag, and the like in this embodiment. These flags are all turned off (= 0) at the initial setting.
First, the control process by the main control board 200 will be described. Under the control of the main control board 200, a main process M shown in the flowchart of FIG. 6 is performed.
In the main process M, an initial setting process (S10) such as a CPU, an interrupt prohibition process (S20), a normal symbol / special symbol main random number update process (S30), an interrupt permission process (S40) are performed, and a loop process is performed in the final process. Is being performed, interrupt processing (S100) is executed every 4 ms.

  In the initial setting process (S10) of the CPU and the like, stack setting, interrupt time setting, CPU setting, SIO, PIO, CTC setting and the like are performed. Although the main process M is repeatedly performed, the initial setting process (S10) of the CPU or the like is an initial control procedure 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 for each of the normal symbol / special symbol main random number update process (S30), and when the update range upper limit value of each random number is reached as described above, The value is returned to the minimum value 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. 7, the output process (S101), the input process (S102), the normal symbol / special symbol main random number update process (S103), the start winning opening detection process (S104), the normal operation Processing (S105), special operation processing (S106), reserved ball number processing (S107), power-off monitoring processing (S108), and other processing (S109) are performed in this order.

In the output process (S101), an output command (command signal) set in each process is transmitted to each control board.
In the input process (S102), signal input is performed when various sensors (switches) attached to the gaming machine 1 are detected.
In the normal symbol / special symbol main random number update process (S103), 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 detection process (S104), as shown in FIG. 8, it is determined whether a winning to the upper start winning opening 41 or the lower start winning opening 42 is detected (S104-1), and a winning is detected. If not, it is determined whether or not the game ball passage to the normal symbol variation start gate 55 is detected (S104-2). When the passing of the game ball to the normal symbol variation start gate 55 is not detected, the start winning opening detection process (S104) is ended. On the other hand, when the passing of the game ball to the normal symbol variation start gate 55 is detected, it is determined whether the number of the normal symbol holding balls is 4 or more (S104-3). The mouth detection process (S104) ends. On the other hand, if the number of the normal symbol reserved balls is less than 4, 1 is added to the number of the normal symbol reserved balls (S104-4), the normal symbol random number value is acquired, and the acquired normal symbol random number value is stored in the RAM of the main control board 200. The normal symbol random number acquisition process stored in the corresponding area is performed (S104-5), and the start winning opening detection process (S104) is completed.

  If it is determined in S104-1 that a winning in the upper starting winning port 41 or the lower starting winning port 42 is detected, it is determined whether the number of special symbol reservation balls is 4 or more (S104-6). In this case, the start winning opening detection process (S104) ends. On the other hand, if the number of special symbol reservation balls is less than 4, 1 is added to the number of special symbol reservation balls (S104-7), and special jackpot random numbers, jackpot symbol random values, reach random numbers, fluctuation pattern random numbers, etc. A special symbol related random number acquisition process for acquiring the symbol related random number and storing it in the corresponding area of the RAM of the main control board 200 is performed (S104-8), and this start winning opening detection process (S104) is completed.

  In the normal operation process (S105), as shown in FIG. 9, it is first confirmed whether the lower start winning opening 42 is open (S105-1). If the lower start winning opening 42 is closed, it is confirmed that the number of normal symbol reserved balls is 0 (S105-2), and if it is 0, the normal operation process (S105) is ended. On the other hand, when the number of normal symbol holding balls is not 0, it is acquired by the normal symbol random number acquisition process (S104-5) of the start winning opening detection process (S104) and stored in the RAM of the main control board 200. The acquired normal symbol random value is read (S105-3), and it is confirmed whether the current probability change is in progress (the probability change flag is ON) (S105-4). If it is not probabilistic, the acquired normal symbol random number value is compared with the established value per normal symbol in the low probability state to check whether they match, and if they match, it corresponds to the normal symbol in the low probability state and matches If not, it is determined that it is off (S105-5). If it is off, the normal operation process (S105) ends. On the other hand, if it is per normal symbol, the lower start winning opening 42 is opened with an opening time of 1 second and the opening number of opening is once. Processing 1 is performed (S105-6), and thereafter, this normal operation processing (S105) ends. On the other hand, if it is determined in S105-4 that the probability change is in progress, the acquired normal symbol random number value is compared with the normal symbol or the established numerical value in the high probability state to check whether or not both match. It is per ordinary symbol in the probability state, and if it does not match, it is determined that it is off (S105-7). In the case of detachment, the normal operation process (S105) is completed. On the other hand, in the case of a normal symbol, the lower start prize opening 42 is opened with an opening time of 2 seconds and the number of times of opening three times. Processing 2 is performed (S105-8), and thereafter, this normal operation processing (S105) ends.

  If it is determined in S105-1 that the lower start winning opening 42 is being opened, it is confirmed whether or not the opening time of the lower start winning opening 42 has passed (finished) (S105-9). When the time has not elapsed, the normal operation process (S105) ends. On the other hand, when the start winning opening opening time has elapsed, a process for closing the lower starting winning opening 42 is performed (S105-). 10) Thereafter, the normal operation process (S105) is completed.

  In the special operation process (S106), as shown in FIG. 10, it is determined which of the special operation status is 1 to 4 (S106-1 to S106-3). When the special operation status is 1, a special symbol standby process (S106-4) is performed, and when the special operation status is 2, a changing process (S106-5) is performed, and the special operation status is In the case of 3, a special symbol confirmation process (S106-6) is performed, and in the case where the special operation status is 4, a special electric accessory process (S106-7) is performed.

In the special symbol standby process (S106-4) performed when the special operation status is 1, as shown in FIG. 11, it is determined whether or not the number of special symbol reservation balls is 0 (S106-4-1). When the number of held balls is 0, it is determined whether or not the display device 10 is in a standby screen (standby screen) where the special symbol is not changing (S106-4-9). Then, the special symbol standby process (S106-4) ends. On the other hand, if it is not in the standby screen (standby screen), a standby screen setting process for making the display device 10 a standby screen (standby screen) is performed (S106-4-10), and then set in standby. (S106-4-11), and then the special symbol standby process (S106-4) is completed. The setting process for setting the standby screen is a command for setting the standby screen when a game ball does not win the upper start winning opening 41 or the lower starting winning opening 42 for a predetermined time after the setting process is performed. Is a process for outputting.
On the other hand, if it is determined in S106-4-1 that the number of special symbol reservation balls is not 0, special symbol jackpot determination processing (S106-4-2) is performed.

  In the special symbol jackpot determination process (S106-4-2), as shown in FIG. 12, first, it is acquired by the special symbol-related random number acquisition process (S104-8) of the start winning opening detection process (S104) and is subjected to the main control. The jackpot random number value stored in the RAM of the substrate 200 is read (S106-4-2-1), and then it is confirmed whether the current probability change is in progress (high probability state) (S106-4-2-2). Whether or not the probability change is in progress is determined to be in the probability change state when the probability change flag is ON, and on the other hand, when the probability change flag is OFF, it is determined to be a low probability state in which the probability change is not in progress. In the case of a low-probability state that is not probabilistic, the acquired jackpot random number value is compared with the jackpot value in the low-probability state to check whether they match. If not, it is determined that it is off (S106-4-2-3). In the case of losing, this special symbol jackpot determination process (S106-4-2) ends. On the other hand, in the case of a jackpot, the jackpot flag is set to ON (S106-4-2-5). This special symbol jackpot determination process (S106-4-2) ends. On the other hand, if it is determined in S106-4-2-2 that the probability change is high (high probability state), the acquired jackpot random number value is compared with the jackpot value in the high probability state to confirm whether they match. If they match, it is a big hit in the high probability state, and if they do not match, it is determined that they are off (S106-4-2-4). In the case of losing, this special symbol jackpot determination process (S106-4-2) ends. On the other hand, in the case of a jackpot, the jackpot flag is set to ON (S106-4-2-5). This special symbol jackpot determination process (S106-4-2) ends. This special symbol jackpot determination process (S106-4-2) corresponds to a win / fail determination means.

Following the special symbol jackpot determination process (S106-4-2), a special symbol selection process (S106-4-3) is performed.
In the special symbol selection process (S106-4-3), a combination of special symbols to be stopped and displayed on the display device 10 (display symbol of the determination result) is determined, and the symbol data that is the basis of the determined symbol is the output It is set here so as to be transmitted to the sub-control board 205 in the process (S101). In the process of the sub-control board 205, a special symbol combination based on the received symbol data is selected and output to the display control board 210.

  In the special symbol selection process (S106-4-3), as shown in FIG. 13, it is first determined whether or not the jackpot flag is ON (S106-4-3-1). A special symbol based on the jackpot symbol random number is set as a stop special symbol (S106-4-3-3). On the other hand, if the jackpot flag is not ON, that is, if it is off, a special symbol data random value (special symbol data 1, special symbol data 2, special symbol data 3) is acquired (S106-4-3-3), It is judged whether the random numbers of the special symbol data 1, the special symbol data 2 and the special symbol data 3 are all coincident (S106-4-3-3-4). (S106-4-3-5). When the reach random number value matches the reach establishment value, the reach is present, and the special symbol assigned to the random value of the special symbol data 1 is added to the random number value of the stop left special symbol and the special symbol data 2 The special symbol assigned to the random number value is set to the special symbol for stopping, and the special symbol assigned to the random number value of the special symbol data 3 is set to the special symbol for stopping right (S106-4-3-6). On the other hand, if the reach random number value does not match the reach establishment value, no reach is reached, and the special symbol assigned to the random value of the special symbol data 1 is changed to the random number value of the left special symbol and the special symbol data 2 The special symbol assigned is the special symbol for stoppage, and the special symbol assigned to the random value obtained by adding 1 to the random value of the special symbol data 3 is set as the special symbol for stop right (S106-4-3-7). .

  If it is determined in S106-4-3-3-4 that the random numbers of the special symbol data 1, 2 and 3 do not match, it is determined whether the random values of the special symbol data 1 and 3 match. (S106-4-3-8). If the random numbers of the special symbol data 1 and 3 match, it is determined whether the reach random number value matches the reach establishment value (S106-4-3-9). If the reach random number value matches the reach establishment value, the reach is present, and the special symbol assigned to the random value of the special symbol data 1 is assigned to the random number value of the stop left special symbol and the special symbol data 2 The special symbol assigned to the random symbol value of the special symbol data 3 which is the special symbol being stopped and the special symbol data 3 is set to the stopped special symbol (S106-4-3-10). On the other hand, if the reach random number value does not match the reach establishment value, no reach is reached, and the special symbol assigned to the random value of the special symbol data 1 is changed to the random number value of the left special symbol and the special symbol data 2 The special symbol assigned is the special symbol for stoppage, and the special symbol assigned to the random value obtained by adding 1 to the random value of the special symbol data 3 is set as the special symbol for stop right (S106-4-3-7). .

  If it is determined in S106-4-3-8 that the random numbers of the special symbol data 1 and 3 do not match, that is, the special symbol data 1, 2, and 3 are all different, the reach random number value is established. It is determined whether or not it matches the numerical value (S106-4-3-11). When the reach random number value matches the reach establishment value, the reach is present, and the special symbol assigned to the random value of the special symbol data 3 is set as the stop left special symbol and the stop right special symbol, The special symbol assigned to the random value obtained by adding 1 to the random value of the special symbol data 3 is set as the special symbol during stoppage (S106-4-3-12). On the other hand, if the reach random number value does not match the reach establishment value, no reach is reached, and the special symbol assigned to the random value of the special symbol data 1 is changed to the random number value of the left special symbol and the special symbol data 2 The assigned special symbol is set to the stopped special symbol, and the special symbol assigned to the random number value of the special symbol data 3 is set to the stopped right special symbol (S106-4-3-10). The special symbol selection process (S106-4-3) corresponds to symbol data determining means, and the symbol data determined here is transmitted to the sub-control board 205 and displayed according to the symbol data in the process of the sub-control board 205. A symbol to be displayed on the device 10 is set. In this embodiment, the symbols to be displayed on the display device are selected by the main control board 200, but may be determined by the sub control board 205. Further, the symbols determined on the main control board 200 are displayed on another display device different from the display device, and the symbols to be displayed on the display device are determined on the sub control board 205 based on the symbol data of the symbols determined on the main control board 200. You can do it. In that case, the display method by the main control board 200 and the sub control board 205 is different, but if the sub control board 205 determines the design based on the data of the main control board 200, the recognition of the mutual design is different. Also good.

After the special symbol selection process (S106-4-3), a special symbol variation pattern selection process (S106-4-4) is performed.
The special symbol variation pattern selection process (S106-4-4) corresponds to variation pattern selection means, and one table (variation pattern table) is selected from a plurality of variation pattern tables based on the determination result, and the selected variation pattern is selected. One variation pattern (variation command) is selected from the table by the variation pattern random value.

  In the special symbol variation pattern selection process (S106-4-4), as shown in FIG. 14, it is first determined whether or not the probability variation is in progress (high probability state) (S106-4-4-1). In the case of a normal state (low probability state) that is not under certain change, it is determined whether or not the big hit flag is ON (big hit) (S106-4-4-2). When the big hit flag is ON (big hit), a fluctuation command for one fluctuation pattern per normal state is selected from the first fluctuation pattern table based on the fluctuation pattern random value (S106-4-4-3). . On the other hand, when the jackpot flag is OFF (disconnected), a variation command of one variation pattern out of the normal state is selected from the second variation pattern table based on the variation pattern random value (S106-4-4). 4).

  On the other hand, if it is determined in S106-4-4-1 that the probability change is in progress (high probability state), it is determined whether or not the big hit flag is ON (big hit) (S106-4-4-5). When the big hit flag is ON (big hit), a fluctuation command of one fluctuation pattern per probability variation is selected from the third variation pattern table based on the variation pattern random value (S106-4-4-6). . On the other hand, when the big hit flag is OFF (disconnected), a variation command of one variation pattern that is out of probability variation is selected from the fourth variation pattern table based on the variation pattern random value (S106-4-4). 7).

  After selecting the variation command of the variation pattern, the selected variation command is stored in the transmission buffer (S106-4-4-8), and other processing is performed (S106-4-4-9). The variation pattern selection process (S106-4-4) ends.

After the special symbol variation pattern selection process (S106-4-4), a special symbol random number shift process (S106-4-5) is performed.
In the special symbol random number shift process (S106-4-5), in the data storage area of the special symbol reservation ball number in the RAM, the number of special symbol reservation balls stored in the storage area of the load (reading) ranking first place. Due to the fact that this data is loaded in the previous process and becomes vacant, the address that advances the loading order one by one with respect to the data of the number of special symbol holding balls stored in the second and subsequent addresses. Shifts are made. Specifically, as shown in FIG. 15, first, 1 is subtracted from the number of special symbol reserved balls stored in the RAM of the main control board 200 (for example, the number of reserved balls of 2 is set to 1 and 3 (S106-4-5-1), and 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 (S106-). 4-5-2) Subsequently, 0 is set to the RAM address corresponding to the number of special symbol reservation balls (the last in the loading order, the fourth in this embodiment) (S106-4-5-3). ).

Subsequent to the special symbol random number shift process (S106-4-5), a special symbol variation start process (S106-4-6) is performed. In the special symbol variation start process (S106-4-6), processing necessary for starting the variation of the special symbol is performed.
After the special symbol variation start process (S106-4-6), the special operation status is set to 2 (S106-4-7), the waiting state is canceled (S106-4-8), and the special symbol standby is performed. The process (S106-4) ends.

  In the changing process (S106-5) performed when the special operation status is 2, as shown in FIG. 16, it is first determined whether or not the special symbol change time (change pattern change time) has ended (S106). -5-1) If the change time has not ended, the changing process (S106-5) is ended. On the other hand, if the fluctuation time has ended, a fluctuation stop command is set (S106-5-2). Subsequently, after the special operation status is set to 3 (S106-5-3) and other necessary processing (S106-5-4) is performed, this in-fluctuation processing (S106-5) ends.

  In the special symbol confirmation process (S106-6) performed when the special operation status is 3, as shown in FIG. 17, it is first determined whether or not the big hit flag is ON, that is, whether or not the big hit flag is set (S106-6). 1). When the jackpot flag is ON, that is, when the jackpot is successful, the jackpot command is stored in the output buffer (S106-6-2), and the special operation status is set to 4 (S106-6-3). The process (S106-6) ends. On the other hand, if the jackpot flag is OFF, that is, it is off, the special operation status is set to 1 (S106-6-4), and this special symbol confirmation process (S106-6) is completed.

  The special electric accessory processing (S106-7) performed when the special operation status is 4 corresponds to special game execution means (big hit game execution means). In the special electric accessory processing (S106-7), as shown in FIGS. 18 and 19, the probability variation flag is turned off (S106-7-1), and it is confirmed whether or not the jackpot opening has been performed on the display device 10. (S106-7-2). If the jackpot opening has not been performed, a jackpot opening command for executing the jackpot opening is set (S106-7-3), and then it is determined whether or not the jackpot end flag is ON (the jackpot game end). (S106-7-4). On the other hand, if the jackpot opening has been performed, it is next determined whether or not the jackpot end flag is ON (the jackpot game ends) (S106-7-4).

  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 45 is currently open (S106-7-5). It is determined whether or not it is the opening time of the mouth 45 (S106-7-6). In the case of the opening time of the big winning opening 45, the opening process of the big winning opening (setting of a big hit round command for displaying during the round, etc.) is performed (S106-7-7), and then this special electric accessory The process (S106-7) ends. On the other hand, when it is not the opening time of the special winning opening 45, the special electric accessory processing (S106-7) is ended.

  On the other hand, if it is determined in S106-7-5 that the big prize opening 45 is open, ten game balls are won in the big prize opening 45 (S106-7-8) or the round end time (in this embodiment). 30 seconds) (S106-7-9) is determined, and if it is none, the special electric accessory processing (S106-7) is terminated as it is, and a special prize opening is received. In the case where 10 game balls in 45 are either winning or the ending time of the round has elapsed, the winning prize closing process (S106-7-10) and the process of subtracting 1 from the value of the round counter (S106-7- 11) is performed. In the special winning opening closing process (S106-7-10), a special winning opening closing command is set in the output buffer. Subsequently, it is determined whether or not the round counter is 0 (S106-7-12). If the round counter is not 0, the special electric accessory processing (S106-7) is finished as it is, and the round counter is processed. When the counter is 0, the jackpot end process (S106-7-13) is performed. In the jackpot end process, preparation for ending is performed and a jackpot ending command is set. Thereafter, the jackpot end flag is turned ON (S106-7-14), and this special electric accessory processing (S106-7) is ended.

  On the other hand, if it is determined in S106-7-4 that the jackpot end flag is ON, that is, if the jackpot end flag is determined, the process of setting the jackpot end flag to OFF (S106-7-15) and the process of turning the jackpot flag OFF. (S106-7-16) is performed, and then it is confirmed whether or not the stop special symbol is a probability variable symbol (odd tick) (S106-7-17), and if the special stop symbol is a probability variable symbol If the probability variation flag is turned on (S106-7-18), on the other hand, if the special symbol for stoppage is not a probability variation symbol but a normal symbol (an even number), the probability variation flag is turned off (S106-7-19). Then, the special operation status is set to 1 (S106-7-20), and this special electric accessory processing (S106-7) is completed.

  Following the special operation process (S106), a reserved ball number process (S107) is performed. In the reserved ball number processing (S107), as shown in FIG. 20, the current reserved ball number is loaded (S107-1), and the reserved ball number is set in the output buffer (S107-2).

  A power-off monitoring process (S108) is performed after the reserved ball number process (S107). In the power-off monitoring process (S108), as shown in FIG. 21, it is determined whether a power-off signal is input (S108-1). If no power-off signal is input, this power-off monitoring process (S108). Ends. On the other hand, when the power-off signal is input, the current data (game state) is stored in the RAM of the main control board 200 (S108-2), and then the power-off flag is set ON (S108-). 3) The power-off monitoring process (S108) ends. The data (game state) stored in the RAM of the main control board 200 is roughly divided into display standby, symbol variation, symbol fixed display, and jackpot game data. (High probability state) and normal state (low probability state) data.

  Following the power-off monitoring process (S108), other processes (S109) are performed. In other processing (S109), other processing necessary for game control is performed.

Processing performed by the sub control board (sub control device) 205 will be described.
In the sub-control main process J performed by the sub-control board 205, as shown in FIG. 22, the CPU initialization process is performed in the sub-control board 205 when the gaming machine 1 is powered on (S201). In the CPU initialization process, settings are made for the external INT interrupt (reception interrupt) process (S300), the 2 ms timer interrupt process (S400), and the 10 ms timer interrupt process (S500). Next, it is determined whether the power-off signal is ON and the contents of the RAM are normal (S202). If the power-off signal is not ON, or if the power-off signal is ON and the contents of the RAM are not normal, such as when the power-off signal is not normal and the contents of the RAM are normal, the RAM is initialized (S203). Thereafter, an interrupt prohibition process is performed (S204). On the other hand, when both the power-off signal ON and the normal contents of the RAM are satisfied, the interrupt prohibition process is performed without initializing the RAM (S204). The processing of S201 to S203 is executed only in the first order when the power is turned on, and is not executed thereafter.

  After the interrupt prohibition process (S204), the random number seed update process (S205) and the interrupt permission process (S206) are performed in a loop process. During this loop process, the external INT interrupt process (S300), the 2 ms timer interrupt process ( (S400) A 10 ms timer interrupt process (S500) is performed.

In the interrupt prohibition process (S205), even if an interrupt occurs, the interrupt is prohibited.
In the random number seed update process (S206), random numbers such as a notice selection random number and a divided random number provided in the sub-control board 205 are updated.
In interrupt permission (S209), execution of the interrupt is permitted.

  In the external INT interrupt process (S300), as shown in FIG. 23, it is confirmed whether the strobe (STB) signal from the main control board 200 is ON (S301), and the strobe signal is ON, that is, the strobe signal is input to the external INT input unit. Is received, the command (control signal) output from the main control board 200 is received and stored in the RAM (S302). On the other hand, if the strobe signal is not ON, the external INT interrupt processing (S300) is completed at that time.

  In the 2 ms timer interrupt process (S400), as shown in FIG. 24, a lamp data output process (S401), a Sw / drive output process (S402), an input process (S403), and a watchdog timer process (S404) are performed. In the lamp data output process (S401), the lamp data created in the 10 ms timer interrupt process described later is output. In the Sw / drive output process (S402), drive data is created and output. In the input process (S403), switch edge data and level data are created. In the watchdog timer process (S404), a watchdog timer process is performed.

  In the 10 ms timer interrupt process (S500), as shown in FIG. 25, the switch state acquisition process (S501), voice control process (S502), notification timer determination process (S503), main command analysis process (S504), Sw process ( S505) and a ramp process (S506) are performed.

In the switch state acquisition process (S501), the switch data created in the 2ms timer interrupt process (S400) is stored as switch data for the 10ms timer interrupt process.
In the sound control process (S502), a process for sound emitted from the speaker 38 is performed.
In notification timer determination processing (S503), processing for time management for performing notification release after a certain period of time has elapsed from notification start and notification cancellation, such as RAM clear and door opening notification.

  In the main command analysis process (S504), an analysis process for all commands received in the external INT interrupt process (S300) and an operation according to the received command are set. The main command analysis process (S504) corresponds to the effect execution means of the present invention. In the main command analysis process (S504), as shown in FIG. 26, first, it is confirmed whether the received command is a variable command (S504-1). If the received command is different from the variable command, the setting process for other commands (S504). -6) is performed, and then the main command analysis processing (S504) is terminated. On the other hand, when the received command is a variable command, a notice lottery process (S504-2) is performed next.

  The notice lottery process (S504-2) is an effect to be displayed in each divided period with respect to the first divided period to the fourth divided period that constitute a period during which the effect is displayed during the display of the special symbol on the display device 10. Process to determine the type. In the notice lottery process (S504-2), as shown in FIG. 27, the first divided period notice lottery process (S504-2-1), the second divided period notice lottery process (S504-2-2), and the third divided period. Period notice lottery processing (S504-2-3) and fourth divided period notice lottery processing (S504-2-4) are performed.

  In the first divided period notice lottery process (S504-2-1), the type of effect displayed in the first divided period is determined. As shown in FIG. 28, a preliminary selection random number is first acquired (S504-2-1-1), and the acquisition preliminary selection random number is 49 or less (S504-2-1-2), 50 to 79, or 80 or more. (S504-2-1-3) is determined in order. When the acquisition notice selection random number is 49 or less, the notice A is set as the type of effect (S504-2-1-4), and when the acquisition notice selection random number is 50 to 79, the notice B is set ( S504-2-1-5), if the acquired advance notice selection random number value is 80 or more, the advance notice C is set (S504-2-1-6), and the first divided period notice lottery process is performed after the type of effect is determined. (S504-2-1) ends. Note that the effect of the notice C is set to the predictive notice effect corresponding to the special effect of the present invention as described above.

  In the second divided period notice lottery process (S504-2-2), the type of effect displayed in the second divided period is determined. As shown in FIG. 29, a preliminary selection random number is first acquired (S504-2-2-1), and the acquisition preliminary selection random number is 49 or less (S504-2-2-2), 50 to 79, or 80 or more. (S504-2-2-2) is determined in order. When the acquisition notice selection random number is 49 or less, notice D is set as the type of effect (S504-2-4-2-4), and when the acquisition notice selection random number is 50 to 79, notice E is set ( S504-2-2-5), when the acquisition notice selection random number is 80 or more, notice F is set (S504-2-2-6), and the second divided period notice lottery process is performed after the type of effect is determined. (S504-2-2) ends.

  In the third divided period notice lottery process (S504-2-3), the type of effect displayed in the third divided period is determined. As shown in FIG. 30, first, a preliminary selection random number is acquired (S504-2-3-1), and the acquired preliminary selection random number is 49 or less (S504-2-3-2), 50 to 79, or 80 or more. (S504-2-3-3) is determined in order. When the acquisition notice selection random number is 49 or less, notice G is set as the type of effect (S504-2-3-4), and when the acquisition notice selection random number is 50 to 79, notice H is set ( S504-2-3-5), if the acquired advance notice selection random number value is 80 or more, the advance notice I is set (S504-2-3-6). (S504-2-3) ends.

  In the fourth divided period notice lottery process (S504-2-4), the type of effect displayed in the fourth divided period is determined. As shown in FIG. 31, first, a preliminary selection random number is acquired (S504-2-4-1), and the acquired preliminary selection random number is 49 or less (S504-2-4-2), 50 to 79, or 80 or more. (S504-2-4-3) is sequentially determined. When the acquisition notice selection random number is 49 or less, notice J is set as the type of effect (S504-2-4-4), and when the acquisition notice selection random number is 50 to 79, notice K is set ( S504-2-4-5), when the acquired advance notice selection random number value is 80 or more, the advance notice L is set (S504-2-4-6), and the fourth divided period notice lottery process is performed after the effect type is determined. (S504-2-4) ends.

  After the notice lottery process (S504-2), in the main command analysis process (S504), the effect of the first divided period determined in the first divided period notice lottery process (S504-2-1) is notice C. Whether or not (predictive notice effect) is confirmed (S504-3), and in the case of the notice C (predictive notice effect), a predictive notice setting process (S504-4) is performed, whereas it differs from the notice C (predictive notice effect) In the case of a notice, a setting process (S504-5) for other notices is performed, and then the main command analysis process (S504) is ended.

  In the predictive notice setting process (S504-4), settings are made for a notice displayed in the first divided period (that is, display of a part of the effects after the second divided period) according to the number of divided periods. In this embodiment, in order to determine the number of divided periods (up to which divided period is displayed) to be displayed during the special effect by this process regardless of the variation pattern, for example, only up to step 1 during the special effect. Even if it is not displayed, a case where an effect is executed until the fourth divided period may occur. With this configuration, it is possible to suppress a reduction in the expectation for the big hit for the variation pattern itself at the time of the first divided period. As shown in FIG. 32, first, a divided random number is acquired (S504-4-1), and it is confirmed whether the acquired divided random number value is 3 or less (S504-4-2). When the acquired divided random number value is 3 or less, the number of divided periods is set to 2 (first divided period and second divided period), and information on effects related to the second divided period is confirmed. The advance notice setting to be displayed is performed (S504-4-3), and then the predictive notice setting process (S504-4) ends.

  On the other hand, if the obtained divided random number value is 4 or more, it is confirmed whether or not there is a reach (S504-4-4), and there is no reach (that is, a combination where the special symbol stop display does not reach the reach state) In this case, as in the case where the obtained divided random number value is 3 or less, the number of divided periods is set to 2 (the first divided period and the second divided period) and the information on the effects related to the second divided period is confirmed. Then, a notice setting to be displayed in the first divided period is performed (S504-4-3), and then the sign notice setting process (S504-4) ends. If it is determined in S504-4-4 that there is a reach (that is, the symbol combination of the special symbol stop display is a symbol combination that has reached the reach state), it is confirmed whether the acquired divided random number value is 6 or less (that is, 4 to 6). (S504-4-5). When the obtained divided random number is 6 or less (that is, 4 to 6), the number of divided periods is set to 3 (first divided period, second divided period, third divided period) and second to third. Information on the production related to the divided period is confirmed, and a notice setting to be displayed in the first divided period is performed (S504-4-6), and then the predictive notice setting process (S504-4) ends.

  On the other hand, when the acquired divided random number value is 7 or more (that is, 7 to 9), the number of divided periods is set to 4 (first divided period, second divided period, third divided period, fourth divided period). At the same time, the information on the effects related to the second to fourth divided periods is confirmed, and a notice setting to be displayed in the first divided period is performed (S504-4-7), and then the warning notice setting process (S504-4). Ends. The precursor / notice setting process (S504-4) corresponds to a divided period number selection unit.

In the Sw process (S505) that is performed after the main command analysis process (S504) is completed, the game operation switch 67 is managed for the valid time (operation valid period) and the operation is performed. The ramp process (S506) is output. Lamp data is created and production time is managed.
In the command transmission process (S507), the command transmission process set in each process is executed.
