FIGS. 5 and 6 are explanatory views for explaining a control for predetermining whether or not the identification information at the time of stop of the variable display device is predetermined specific identification information (a big hit symbol). It is a figure.

Before the variable display device 5 is stopped, the variable display device 5 determines in advance whether or not the identification information at the time of stop should be the specific identification information, and the identification at the time of stop is made based on the contents of the determination. The type of information (design) is determined, and the display is controlled so as to have the determined content. Figure 5
It shows the decision method in the normal state which is not the high probability state. The high-probability state is a state in which the display result when the variable display device 5 is stopped is highly likely to be the specific identification information. Random A is a random counter for determining whether or not the display result when the variable display device is stopped is set as the specific identification information to make a big hit.
When it counts up to 7 and then to 27, it counts up from 0 again. The random counter A is incremented by "1" each time the game control program is executed once every 2 msec, for example. The random counter B is also a counter for determining whether or not the jackpot is generated by using the display result when the variable display device 5 is stopped as the specific identification information, and when it is counted up from 0 to 9 It is to count up from 0 again. This random counter B has a program of 1 every 2 msec.
It is incremented by "1" each time it is executed, and is repeatedly counted up during the reset waiting time after the game control program has been executed once. In addition, the random counter C + 2, the left symbol display unit 3
1a is a counter for determining the symbol displayed when stopped, random C + 1 is for determining the display symbol when the middle symbol display portion 31b is stopped, random C + 0 is when the right symbol display portion 31c is stopped It is for determining the display symbol. Random counter C + 2 is 2msec
Every time the program is executed once, "1" is added, and the program is repeatedly added during the reset waiting time described above. The random counter C + 1 is incremented by "1" when the random counter C + 2 has finished counting to "6" and then carried to the next count. The random counter C + 0 counts up to "6" in the random C + 1 and increments by "1" when carried from the next count. The random counters C + 2, C + 1, and C + 0 corresponding to the seven types of count values (0 to 6) described above are used.
Display patterns of types are defined.

When deciding whether or not to make a big hit, the count value of the random counter A is first extracted when the normal probability is not in the high-probability state, and when the extracted count value is "1", the count value is further extracted. The count value of the random counter B is extracted, and when the count value of the random counter B is also “1”, it is determined that the big hit should be generated. In that case, as shown in the figure, the count value of the random counter C + 2 is extracted, and the left symbol display portion 31a, the middle symbol display portion 31b, and the right symbol display portion 31c are displayed using the extracted count value. Control. As a result, the symbols displayed when the symbol display portions 31a to 31c are stopped become the same type of symbols (so-called double eyes).

On the other hand, when the count value extracted from the random counter A is other than "1", it is immediately determined to be out, and as shown in the drawing, the left symbol display portion is based on the count value extracted from the random counter C + 2. 31a is display-controlled, the middle symbol display portion 31b is display-controlled based on the count value extracted from the random counter C + 1, and the right symbol display 31c is display-controlled based on the count value extracted from the random counter C + 0. Also,
Even if the count value extracted from the random counter A happens to be "1", when the counter value extracted from the random counter B is other than "1", it is determined as the same as the above, and each random counter is determined to be out of sync. C + 2
The display of each of the symbol display portions 31a to 31c is controlled based on the count values of C + 1 and C + 0. In addition, each random counter C + extracted when it is determined to be out of alignment
When the extracted data from 2, C + 1, C + 0 happens to be the same value, the display control as it is causes the symbols displayed by the symbol display portions 31a to 31c to become so-called ditches. In that case, "1" is subtracted from the value of the random counter C + 1 to forcibly remove the symbol.

As described above, in the normal state which is not the high probability state, the probability of hitting is 1/28 × 1/10.
= 1/280.

Next, when the special device is activated to enter the right generation state and then the operation of the special device is stopped to extinguish the right, a high probability state is set. In this case, the method shown in FIG. 6 predetermines whether or not to generate a big hit. First, the count value of the random counter A is extracted, and when the extracted count value is "1", the count value of the random counter B is immediately determined without extracting, and based on the data extracted from the random counter C + 2. And the respective symbol display portions 31a to 3
Display control of 1c. On the other hand, when the counter value extracted from the random counter A is other than "1", it is determined as a hit other than the big hit, and each random counter C +
2, C + 1, C + 0 based on the respective counter values extracted, the respective symbol display portions 31a, 31b, 31
Display control of c. Incidentally, each random counter C happens to be
When the values extracted from +2, C + 1, and C + 0 are the same value, "1" is subtracted from the random counter C + 0 in the same manner as described above, and the pattern is forcibly removed.

As described above, in the high probability state, the probability of a big hit is 1/28.

FIG. 7 is a timing chart showing the relationship between the timing of extracting the count value of each random counter and the variable display operation by each symbol display unit.

As shown in the figure, the pachinko ball has an operating opening 6
When a winning prize is detected by the operation opening winning prize detector 7 (see FIG. 1), the detection pulse is output as shown. At the falling edge of this detection pulse, the count value of the random counter A for determining the hit or miss is extracted and stored. Then, 0.00 from the trailing edge of this detection pulse
The count value of the random counter C + 2 for the left stop symbol determination is extracted with a delay of about 2 to 0.008 seconds, and the respective symbol display portions 31a to 31c are simultaneously variably started. The variable display of the left symbol display portion 31a is stopped after 5.080 seconds have elapsed after the start of the variable. This left symbol display section 31
Simultaneously with the stop of the variable display of a, the count value of the random counter B is extracted, and each of the random symbol C + 1 for stopping symbols in the middle symbol display portion and the random counter C + 0 for determining symbols in the right symbol display portion is determined. The count value is extracted. The variable display of the middle symbol display portion 31b is stopped 0.600 seconds after the variable display of the left symbol display portion 31a is stopped.

Next, the variable display of the left symbol display portion 31c is
There are two types depending on the reach state and the non-reach state. This reach state is a state in which the stop symbols of the left symbol display portion 31a and the right symbol display portion 31b are the same type of symbols, and there is a possibility that a big hit may be displayed depending on the display symbol when the right symbol is stopped. Is. When not in the reach state, the variable display of the right symbol display portion 31c is
It stops 0.600 seconds after the middle symbol display portion 31b stops. On the other hand, in the reach state, the variable display on the right symbol display portion 31c continues to be variably displayed for 4.000 seconds after the middle symbol display portion 31b is stopped, and then the stop control is entered, and the display is not displayed. It takes 0 to 2.008 seconds for stop control depending on the type of pattern to be performed.

As described above, the stop symbol of the left symbol display portion is determined when the variable display device starts variable, and the stop symbol of the middle symbol display portion and the right symbol display portion is determined when the left symbol is stopped.

FIG. 8 is a timing chart showing the relationship between the operating state of the variable display device and the operating state of the first variable winning ball device.

As shown in the figure after the fluctuation of the right symbol display portion 31c of the variable display device 5 is stopped, it is determined whether or not it is predetermined to generate a big hit after 1.00 seconds, and a big hit is generated. When it is determined that it is predetermined to be performed, the first variable winning ball device 8 is opened and switched to the first state. As described above, the first state of the first variable winning ball device 8 ends when the earlier of the predetermined period of time or the winning of the predetermined number of pachinko balls, whichever comes first. , In FIG.
The figure shows a case where the process is completed after the elapse of a predetermined period. As shown in the figure, the first state is completed and the first variable winning ball device 8 is closed and the second state is obtained when 5.800 seconds have elapsed. Switch to. In that state, if there is a winning record of a pachinko ball to the operating opening 6 (see FIG. 1), 0.008 seconds have elapsed after the first variable winning ball device 8 was switched to the second state. Then, each of the symbol display portions 31a to 31c of the variable display device 5 starts variable again. In this way, when there is a winning memory in the operating port 6, whether or not the special device is activated and is in the right generation state at the stage when the first variable winning ball device 8 is switched to the closed state. Regardless of this, the variable display device 5 starts to change again. If the variable display device 5 starts to change again in the state where the right is generated and the specific display information (so-called doublet) again when the variable display device 5 is stopped, the first variable winning is again performed. The ball device 8 opens. On the other hand, when a pachinko ball wins the open variable winning ball device 8 and is guided to the winning opening 12 to win the prize, the right generation state that is currently in progress disappears and the process ends. But,
Even if the pachinko ball wins the winning opening 12 again while the right is generated, the right-generating state that is currently in progress may be continued to the end. In addition, the winning holes for pachinko balls that have rights
It is also possible to memorize the winning award again, and to cause the next right occurrence state based on the memory to appear after the current right occurrence state continues to end to the end.

FIG. 9 is a timing chart showing the operating state of the variable display device 5 when the display result when the variable display device 5 is stopped does not serve as specific identification information and does not result in a big hit.

When the variation of the right symbol display portion 31c of the variable display device 5 is stopped and 1.000 seconds later, the pre-determined content of whether to make a big hit or not is determined, and when it is decided not to make a big hit, , 1.000 seconds later, and then 0.
When 008 seconds have passed and there is a winning memory for the pachinko balls in the operating opening 6, the variable display device 5 starts variable again as shown in the figure.

FIG. 10 is a timing chart showing the operating state of the special device and the timing of occurrence of the high probability state.

As shown in the figure, when the special device is activated to generate the first right generation state, and the special device is stopped to finish the first right generation state, the specific display of the variable display device 5 is performed. A high probability state occurs in which the probability of becoming information is improved. This high probability state is 2
When the right occurs for the second time, it ends and returns to the normal probability state. Then, when the second special device operation is stopped and the second right generation state ends, the high probability state is restored again, and the third special device operation causes the third right generation state to occur. The probability state ends and the normal probability state is reached. Then, even if the operation of the special device for the third time is completed and the right occurrence state for the third time is completed, the high probability state for the third time does not occur. In other words, the special device operates three times, so that the probability does not change.
In addition, in the present embodiment, the state in which the probability does not fluctuate when the special device is operated three times has been described. However, the present invention is not limited to this point, and the number of times the end of the operation of the special device is unlimited without limitation. However, it may be configured so that the probability varies.

FIG. 11 is a flow chart showing the operation for determining the stop symbol of the variable display device.

In step S (hereinafter simply referred to as S) 1, it is determined whether or not there is a start winning. If a pachinko ball wins the operating port 6 (see FIG. 1) and is detected by the operating port winning ball detector 7, the process proceeds to S2, and the first-stage lottery process is performed. The first-stage lottery process is a process of extracting the count value of the random counter A described with reference to FIG. Then, it is determined in S3 whether or not the lottery count value is a hit, that is, whether or not it is "1", and if it is determined that it is not a hit, the process proceeds to S8,
Random counter C + for stop symbol determination on the left symbol display
It is determined whether or not the count values extracted from 2 and the random counter C + 1 for determining the stop symbol in the middle symbol display unit and the random counter C + 0 for determining the stop symbol in the right symbol display unit are all the same value. .. If it is determined that they do not have the same value, the process of storing the value of each stop symbol determining random counter in the corresponding area is performed in S10, but by chance, each count value is left = middle = right. When it is, the process of S10 is performed after the process of subtracting "1" from the right symbol is performed in S9. This is to prevent the stop symbols of each symbol display unit from becoming the same symbols as the symbols of the same type (so-called double eyes), even though it is predetermined that the symbols are not hit, as described above. Is.

On the other hand, if it is determined that the result of the extraction process of the first stage is a hit, the process proceeds to S4, and it is determined whether or not the high probability state is set, and if the high probability state is set. To S7 as it is, the middle symbol and the right symbol are combined with the count value extracted from the random symbol C + 2 for determining the stopped symbol on the left symbol display section, and the respective values are set to the corresponding areas as left = middle = right. A process of storing is performed. That is, in the high probability state, it is determined whether or not to make a big hit, based only on the count value extracted in the first-stage lottery process, that is, the count value of the random counter A shown in FIG. is there.

On the other hand, if it is judged to be a hit by S3 and S
When it is determined that the state is not the high-probability state by S4, S5
Thus, the second-stage lottery process is performed. The second-stage lottery process is a process of extracting the count value of the random counter B shown in FIG. Whether or not the count value extracted as a result of the second-stage lottery process is a win, that is, whether or not it is "1" is determined in S6, and if it is determined that the count value is not a win, the process proceeds to S8. However, if it is determined that the hit is successful, the process proceeds to S7.
In this way, when the high probability state is not set, as shown in FIG. 5, the count value of the random counter A based on the first stage lottery process and the count value of the random counter B based on the second stage lottery process. Only when both the value and the hit value are "1", the process for making a big hit in S7 is performed. By S2 to S6, the probability variation control means is configured to control the probability that the display result when the variable display device is stopped becomes the specific identification information, based on the establishment of the predetermined probability variation condition. There is.

Next, another embodiment of the present invention will be described. (1) When the variable display device 5 is in a predetermined display state, the probability variation condition may be satisfied and the high probability state described above may be started. The predetermined display of the variable display device 5 is
For example, all displays that are jackpots, specific displays that are predetermined among the displays that are jackpots, specific displays that are predetermined other than the displays that are jackpots, and the like are conceivable. In addition, if a high probability state occurs when all of the jackpot displays or a predetermined specific display among the jackpot displays, the high probability state may be started with the occurrence of the jackpot, The high probability state may be started after the jackpot ends.

(2) At the time of winning a pachinko ball to the operating port 6, if the count value extracted from the random counter A for determining the hit or miss is a predetermined value, the probability variation condition is satisfied and a high probability state is established. You may start it.

(3) When the special device is activated, the probability variation condition may be satisfied to start the high probability state.

(4) When the hitting ball passes through a specific passing area, the probability varying condition may be satisfied to start the high probability state. In this case, the number of passing balls to the passing area may be one or a predetermined number. Further, this specific passing area may be formed in the game area, or a variable winning ball device such as a high probability state when a pachinko ball enters the normal winning hole 36 of FIG. 2, for example. The area in which the prize can be won when the game is opened may be a specific passage area.

(5) If the variable display device 5 does not become the jackpot display state within a certain period (or a certain number of times), the probability variation condition may be satisfied to start the high probability state.

(6) The probability variation condition may be satisfied and the high probability state may be started when the number of difference balls or the payout rate of the pachinko gaming machine reaches a predetermined value. The number of difference balls and the ball output rate are
It may be from the opening of the game hall or from a predetermined time other than the opening.

(7) A probability varying variable display device for determining whether or not to vary the probability is separately provided, and the display result when the probability varying variable display device is stopped has a predetermined pattern. In this case, the probability changing condition may be satisfied to start the high probability state.

(8) When the conditions described in (1) to (4) above are satisfied, the probability variation condition may be satisfied and the high probability state may be terminated to return to the normal probability state. ..

(9) When a predetermined period of time has passed after the start of the high probability, the probability variation condition may be satisfied, the high probability state may be terminated, and the normal probability state may be restored. The predetermined period is, for example, of a predetermined time period, a period required for the variable display of the variable display device to perform a predetermined number of times, a period of the predetermined time period or a period of the variable display of the variable display device performed for a predetermined number of times. It is possible to consider an earlier period, a period until the number of times the display result when the variable display device is stopped becomes a winning display result reaches a predetermined number, and the like.

(10) When the memory for winning a pachinko ball in the operating port 6 is lost, the probability variation condition may be satisfied, the high probability state may be terminated, and the normal probability state may be restored.

(11) It is also possible to establish a probability variation condition to end the high-probability state and return it to a normal probability state when the number of differences in the number of pachinko balls or the payout rate reaches a predetermined value. The number of difference balls and the payout rate may be from the opening of the game arcade, a predetermined time other than the opening of the game arcade, or a high probability start. (12) Instead of preliminarily determining the hit or miss before the variable display device 5 is stopped, it is determined whether or not the stop symbol is a jackpot after the variable display device 5 is stopped. Good.

(13) The variable display device 5 is always variably displayed, and the symbol displayed by the variable display device 5 at the time of winning the pachinko ball into the operation opening 6 is a certain specific symbol (for example, 7). When it is determined to be a jackpot when it is a doublet, each of the symbol display portions 31a to 31c
Even if the display time of the symbol variably displayed by lengthening the display time of the certain specific symbol (for example, 7) or conversely shortening it to a high probability state or a normal probability state Good.
