FIG. 4 is an explanatory diagram for explaining various random counters used for game control and variable display control of the variable display device 4. The C RND1 is used for pre-determining whether or not a big hit is generated, and is configured to count up from 0, count up to 224 which is the upper limit thereof, and count up again from 0. The addition and update of this count-up are performed by adding 1 to C RND1 for each interrupt processing. The CPU provided on the game control board described above is periodically (for example, every 2 msec) a reset signal is input from the regular reset circuit, and the program is executed from the beginning to the end and is then in a reset waiting state. It is possible to control the gaming state of the gaming machine by repeating the execution of the program again from the beginning when the reset signal is input and repeating the execution of the program from the beginning to the end each time the reset signal is input. Is configured. Then, each time this reset pulse is input, for example, every 2 msec, this C RN is input.
D1 is added and updated by "1".

C RND ZU1 is the type of planned stop symbol to be displayed when the left, middle, and right variable display portions of the variable display device 4 when it is predetermined as a big hit, and when it is predetermined to be off It is used to determine the type of scheduled stop symbol to be displayed when the left variable display section of the variable display device 4 is stopped, and is counted up from 0 and then up to 14 which is the upper limit thereof, and then again. It is counted up from 0 again. The update of the count-up is performed by adding C RND ZU1 by "2" by an infinite loop using the interrupt processing surplus time. The CPU executes "2" for the value of this CRND ZU1 by an infinite loop by using the interrupt processing surplus time until the reset signal is input when the program is executed from the beginning to the end.
Is added and updated, and when the result of the addition exceeds the upper limit of "14", the processing of adding and updating again from "0" by 2 is performed again.

Next, the C RND ZU2 is used to predetermine a scheduled stop symbol to be stopped and displayed on the middle variable display portion of the variable display device 4 when it is previously determined to be off, and is counted from 0. After counting up to 14 which is the upper limit, it is counted up again from 0. This count-up is updated by the above C
C RND ZU2 at carry of RND ZU1
Is performed by adding "1" each. That is, when the value of CRND ZU1 changes from "14" to "0", this CRND ZU2 is added and updated by "1".

Next, the C RND ZU3 is for predetermining a planned stop symbol which is to be stopped and displayed on the right variable display portion of the variable display device 4 when it is previously determined to be off, and is counted up from 0. Is the upper limit 14
After counting up to 0, it is counted up from 0 again. The update of this count-up is performed by the CRN.
This is performed by adding "1" to CRND ZU3 at the carry of D ZU2. That is, when the value of C RND ZU2 changes from "14" to "0", C RND ZU3 is added and updated by "1".

Next, C RND R1 is used to determine whether or not reach display is to be performed. After counting up from 0 and counting up to 15 which is the upper limit thereof, counting up from 0 again. It will be fixed. And the update of the count-up is CRND
This is performed by adding "1" to CRND R1 at the time of carry of ZU3. That is, CR
When the value of ND ZU3 changes from “14” to “0”, C RND R1 is added and updated by “1”. When the value of CRND R1 is "0", it is determined to perform reach display.

Next, C RND R2 is used to determine the type of reach, and is counted up from 0, counted up to its upper limit of 19, and then counted up from 0 again. is there. And
The update of the count-up is performed by incrementing C RND R2 by "1" when the carry of C RND R1 is performed. That is, when the value of CRND R1 changes from "15" to "0", CRND R1
2 is added and updated one by one. This C RN
The value of DR2 and the type of reach are associated in advance.

There are three types of reach: normal reach, super reach 1 and super reach 2.
Here, the normal reach refers to a normal reach state. Super reach is a reach in which the stop symbol after the reach display is set to have a high jackpot rate. That is, when the super reach is displayed on the variable display device 4, the ratio of the subsequent stop symbols being the combination of the big hit symbols is higher than that in the normal reach.
The ratio will be described later. In the case of this pachinko game machine, 2 of Super Reach 1 and Super Reach 2
There are different types of super reach.

FIG. 5 is a flow chart showing a procedure for determining in advance whether or not a big hit will be generated based on the value of the random counter. If a hitting ball enters the starting opening 9 and is detected by the starting ball detector 21, the value of CRND1 at that time is extracted, and when the extracted value is "3", a big hit is determined in advance. It In that case,
The symbol to be a big hit is determined by the extracted value of C RND ZU1.

On the other hand, when the extracted value of CRND1 is other than "3", the deviation is predetermined. In that case, C
The scheduled stop design of the left variable display section is determined by the extracted value of RND ZU1, and the scheduled stop design of the middle variable display section is determined by the extracted value of C RND ZU2, C RND
The scheduled stop symbol of the right variable display portion is determined by the extracted value of ZU3.

When the three scheduled stop symbols are decided, if the decision contents are, for example, a doublet and the combination of symbols for generating a big hit happens to coincide, the extracted value of CRND ZU2 is set to "1". ”Is added to forcibly control so that the pattern is out of alignment.

When it is determined that the reach display is performed based on the extracted value of C RND R1 described above, a process of matching the value of C RND ZU3 with the extracted value of C RND ZU3 is performed. That is, C RN
The symbol to be reached is determined by the extracted value of D R1. The reason for performing such a process is that even in the case of deviation, it can be decided to perform the reach display based on the extracted value of C RND R1.

When the gaming state is a probability improving state (high probability state) described later, the extracted value of C RND1 is
It is predetermined that a big hit is generated at 3, 5, 7, 11, and 13, and at other times, the deviation is predetermined.

Here, the probability improvement state will be described.
The probability improving state is a state in which the probability that a big hit occurs is improved, and in the probability improving state, the following control is performed. When the display result of the variable display device 4 at the time of occurrence of the big hit state is a combination of predetermined special identification information, the probability is controlled to a high probability state in which the probability that a big hit will occur thereafter is improved. Then, in the high probability state, the probability of displaying a combination of specific identification information (specific display mode) predetermined to be a big hit displayed by the variable display device 4 is improved, When a specific combination of identification information is displayed on the variable display device 4, the big hit control is started again. Further, in this probability improvement state, the probability that a small hit occurs on the normal symbol display 14 is controlled to be high. Further, in that case, control for shortening the variation time of the symbol (first symbol) on the normal symbol display 14 is also performed. By performing such control, the frequency with which the movable piece 24 opens is increased, and as a result, the ball is in a state in which it is easy to start and win.

Further, in this gaming machine, the arrangement configuration of the symbols (second symbols) variably displayed on the variable display device 4 is predetermined. For example, in the left, middle, and right variable display sections, a plurality of symbols are defined in the same arrangement. And the symbol position corresponding to each of those symbols is allocated corresponding to each symbol. And
The symbol at the location where each extracted value of C RND ZU1, 2, 3 matches the symbol position number is selected and determined as the scheduled stop symbol.

FIG. 6 is an explanatory view for explaining the types of varying states of symbols in the variable display device 4. There are four types of variation states (variation patterns) A to D in the variation state of symbols.

In the variable display device 4, basically, the symbols are variably displayed by scrolling the symbols. In the fluctuation state A, the fluctuation speed of the symbol is gradually accelerated, and then is made constant. In the fluctuation state B, the fluctuation speed of the symbol is gradually reduced, and then the symbol is stopped. In the fluctuation state C, the symbols are displayed at a fixed place without scrolling, and the symbols are switched on the spot. This fluctuation state C is a display of super reach 1. In the fluctuation state D, from the front of the two symbols to be the target of the big hit, a slow and slow fluctuation is made until the symbol to be the big hit passes, and in other cases, a fast and fast fluctuation is made. This fluctuation state D is a display of the super reach 2.

Next, the relationship between the extracted value of C RND R2 and the determined reach type will be described. C RN
The determination of the reach type based on the extracted value of DR2 is performed using a reach type determination table described below.

FIG. 7 is an explanatory diagram showing the contents of the reach type determination table. In the reach type determination table shown in FIG. 7, C RND R2 for each gaming state
The relationship between the extracted value and the type of reach to be executed is predetermined.

The details are as follows. The playing state is
It is classified into two types, one when it is out and when it is a big hit.

In the case of disengagement, the relationship between the extracted value of CRND R2 and the type of reach is defined as follows. When the extracted value is “0” to “16”, execution of the normal reach is determined. Extracted value is "17"
When it is "18", execution of super reach 1 is determined. When the extracted value is “19”, execution of super reach 2 is determined.

In the case of a big hit, the relationship between the extracted value of C RND R2 and the type of reach is defined as follows. When the extracted value is “0” to “5”, execution of normal reach is determined. Extracted value is "6" to "1"
If it is “2”, execution of super reach 1 is determined. When the extracted value is “13” to “19”, execution of super reach 2 is determined.

Next, the relationship between the type of reach and the probability of a big hit (hereinafter, the big hit expectation) will be described.

FIG. 8 is an explanatory diagram showing the relationship between the reach type and the jackpot expectation. In FIG. 8, normal reach, super reach 1 and super reach 2,
The relationship between the appearance rate at the time of a big hit with respect to all the fluctuations (all the variable display numbers), the occurrence probability at the time of a deviation with respect to all the fluctuations, and the expectation degree of the big hits is shown.

Referring to FIG. 8, the appearance probability at the time of a big hit for all fluctuations is "6/450 in the case of normal reach.
0 "," 7/4500 "in the case of super reach 1, and" 7/4500 "in the case of super reach 2. This appearance rate is the probability that a reach that becomes a big hit appears with respect to all fluctuations including a big hit and a deviation. Taking the normal reach as an example, it is obtained as follows. In other words, this appearance rate is {CRNDR
Probability that execution of normal reach is determined by 2 (Fig. 7
)} × {probability that jackpot execution is determined by C RND1 (see FIG. 4)}. In the case of normal reach, the appearance rate is {6/20} × {1/225}
= {6/4500}. That is, if the symbol changes 4500 times (variable display is performed), the 6 times big hit of normal reach will appear. In addition, the appearance rate in the case of Super Reach 1 and Super Reach 2 is also
It is calculated in the same manner as in the case of the normal reach described above.

The appearance rate at the time of deviation with respect to all fluctuations is "238/4500" in the normal reach, "28/4500" in the super reach 1 and "14/4500" in the super reach 2. This appearance rate is the probability that a reach that is out of line will appear with respect to all fluctuations (variable display) including a big hit and out-of-range. Taking normal reach as an example, it is calculated as follows. That is, this appearance rate is {probability that normal reach execution is determined by C RND R2 at the time of deviation (see FIG. 7)}.
X {probability that the reach display is decided by C RND R1 (see FIG. 4)} x {probability that the deviation is decided by C RND1}. In the case of normal reach, the appearance rate is {17/20} × {1/16} ×
{224/225} = {238/4500}. That is, if the design changes 4500 times (variable display is performed), the deviation in the normal reach appears 238 times. Note that the appearance rate in the case of super reach 1 and super reach 2 is also calculated in the same manner as in the case of normal reach.

Also, the jackpot expectation (%) is "2.5%" in the case of normal reach, "20.0%" in the case of super reach 1, and "33.3 in the case of super reach 2".
% ”. This jackpot expectation (%) is the probability of a jackpot when a reach appears. The jackpot expectation is calculated as follows for each type of reach. That is, the jackpot expectation rate (%) for each reach type is calculated by {occurrence rate of jackpots against all fluctuations} / [{occurrence rate of jackpots against all fluctuations] + {occurrence rate of deviations from all fluctuations}] To be In this way, the jackpot expectation is set to have a higher probability in the case of super reach 1 or super reach 2 than in the case of normal reach.

Next, with reference to FIG. 9, the procedure of variable display of the variable display device 4 will be described. The time marked with * in FIG. 9 is the time at the high probability.

FIG. 9 is a timing chart showing a variable display control procedure of the variable display device including the case where the reach is not generated and the case where the reach is generated.

A hit ball is won in the variable winning ball device 10, and the winning ball is detected by the starting ball detector 21 (see FIG. 1). At the timing when the detection pulse rises, the CPU extracts the value of CRND1 and stores the value in the RAM. Then, after 0.002 seconds have elapsed since the start winning of the ball hitting the start opening 9 was detected, the CPU detects the value of C RND1 stored in the RAM at the falling timing of the detection pulse. Read and judge. At the same time, the CPU is responsible for CRND R1 and CRND R
Extract each value of 2. In this case, the CPU
Decides to be out according to the value of CRND1,
The variable display of the variable display device 4 is controlled based on the determination result.

Then, after the start prize is received, 0.21
After 6 to 0.230 seconds, CRND ZU1 to C
The respective values of RND ZU3 are extracted, and at the same time, the variation of the symbols is simultaneously started on each of the left, middle, and right variable display portions.

In the left variable display portion, the display control of the fluctuation state A is performed for 5.340 seconds after the fluctuation starts. After that, the variation state B is controlled for 1.000 seconds. In this fluctuation state B, first, the symbols before the 6 symbols of the stopped symbol determined by the value of C RND ZU1 are set, and then the variable display for 6 symbols is performed within 1.000 seconds, and finally. The control is performed so that the variable display is stopped with a predetermined stop symbol. At a high probability, the time of the fluctuation state A is 2.840 seconds. This is the same reason that the variation time of the first symbol is shortened, the variation time of the second symbol at the time of high probability in the variable display device 4 is shortened, and the starting memory of the second symbol is stored. Is to be quickly digested.

In the right variable display portion, the fluctuation display is controlled in the fluctuation state A for 6.340 seconds after the fluctuation is started,
After that, the fluctuation display is controlled in the fluctuation state B for 0.650 seconds. The display control in the changing state B is, similarly to the left variable display section described above, after setting a symbol before 6 symbols of a predetermined stop symbol, varying the 6 symbols in 0.650 seconds, and finally. , The variable display is stopped and controlled by the determined stop pattern. Further, when the probability is high, the time in the fluctuation state A is shortened to 3.840 seconds as in the left side.

When the reach display is not executed, the middle variable display section controls the display in the changing state A for 6.990 seconds after starting the changing display, and then displays the changing display in the changing state B for 0.650 seconds. Control. The display control in the variation state B is to set the symbols before the 6 symbols of the predetermined stop symbol and then variably display the 6 symbols in 0.650 seconds,
Finally, the variable display is stopped with the determined stop design.
Further, when the probability is high, the time of the fluctuation state A is shortened to 4.490 seconds.

When the reach display is executed, the variable display mode of the middle variable display section is different from that in the case where the reach display is not executed. When the reach display is executed, first, in the medium variable display portion, the variable display in the variable state A is performed as in the case where the reach display is not executed, and then 1
The display is controlled in any one of the fluctuation states B, C, or D in the period of 5.00 to 23.000 seconds. In the changing state in this case, 26 to 42 symbols are displayed in a changing manner. In this case, the variation state B, C or D is selected as C.
Determined by the extracted value of RND R2.

As described above, in this gaming machine, it is possible to display, for example, two types of super reach 1 and super reach 2. Therefore, the player can change the variable display device 4 to the super-reach 1
Alternatively, when Super Reach 2 is displayed, the expectation for the occurrence of a big hit increases.

In this pachinko gaming machine, when the reach display including all of the normal reach, the super reach 1 and the super reach 2 is not made for a predetermined period, any kind of reach state is forcibly displayed on the variable display device 4. The control (hereinafter, referred to as reach compulsory display control) is performed. This reach display control is executed in association with the execution of the main routine of the control program executed by the basic circuit 40 of the game control board shown in FIG.

FIG. 10 is a flow chart showing the control operation of the reach reach display control. Referring to FIG. 10, in step S (hereinafter, simply referred to as S) 1, the result of the hit or miss (big hit or other than big hit) determined by the value of CRND1 extracted according to the start winning is referred to, and S2
Thus, it is determined whether or not the reference result is a big hit.

When it is determined in S2 that the jackpot is a big hit,
Proceed to S4, the jackpot flag is set, and then proceed to S7, which will be described later. Here, the big hit flag is a flag that is set when it is determined in advance that a big hit will be generated, is set in S4, and then is cleared by another routine when the big hit state ends.

On the other hand, if it is determined in S2 that the jackpot is not a big hit, the process proceeds to S3, and it is determined whether or not the reach display is performed. If it is determined in S3 that the reach display is performed, the process proceeds to S7, which will be described later. On the other hand, if it is determined in S4 that the reach display is not performed, the process proceeds to S5.

At S5, it is determined whether or not the predetermined period has expired. The predetermined period in this case is a period after execution of the reach display (including normal reach, super reach 1, and super reach 2) executed last time, and is predetermined. The detection of the elapse of the predetermined period is started by the predetermined period detecting means in S8 described later. Here, the predetermined period detection means is included in the timer 56. The predetermined period detection means starts the detection of the period when set and ends the detection of the period when cleared.

If it is determined in S5 that the predetermined period has not expired, the processing of this routine ends. On the other hand, S
When it is determined in 5 that the predetermined period has expired, the process proceeds to S6. In S6, CRN which is a random number for determining the reach type
A process of determining the type of reach to be displayed based on the extracted value of D R2 and displaying the reach of the determined type on the variable display device 4 is executed. That is, if it is determined that the predetermined period has expired since the last reach display was executed,
Execution of any kind of reach indication is forced. After the process of S6 is performed, the step proceeds to S7.

At S7, processing for clearing the detecting means for a predetermined period is performed. As a result, the detection of the elapse of the predetermined period is once terminated. After that, in S8, a process of setting the detecting means for a predetermined period is performed. As a result, the detection for the predetermined period is restarted. After S8, the processing of this routine ends.

In the above description, the case where the timer 56 is the predetermined period detecting means is shown. That is, the predetermined period detected is a predetermined operating time of the gaming machine (time when there is a hit ball). However, the present invention is not limited to this, and the predetermined period to be detected may be a period in which the variable display (variable display) is performed a predetermined number of times. In this way, when the variable display of the predetermined number of times is detected, instead of the timer 56 described above,
The counter 55 is used.

In the above description, an example in which the forced reach display is performed only once has been shown. However, not limited to this, the forced reach display may be performed twice or more. Further, the forced reach display may be performed until the variable display is performed a predetermined number of times, or until the predetermined operating time elapses.

The contents of the reach compulsory display control described above are summarized as follows. A determination is made as to whether or not a predetermined period (a predetermined operating time or a predetermined number of variable display times) has elapsed after execution of any type of reach display.
If neither reach display is executed within a predetermined period after the reach display is executed, display of any kind of reach is forcibly executed.

By performing the reach forced display control as described above, the following effects can be obtained. When the reach display is not executed for a predetermined period of time, the reach display is forcibly executed, so that it is possible to improve the interest without impairing the player's willingness to play.

Second Embodiment Next, a second embodiment will be described. In the second embodiment, when the reach display including all of the normal reach, the super reach 1 and the super reach 2 is not displayed for a predetermined period, control for improving the probability that the reach state is displayed (hereinafter referred to as reach probability improvement control. ) Will be described in the pachinko gaming machine described above. The contents of the reach probability improvement control will be described below.

When the reach probability improving control is performed,
The relationship between the extracted value of C RND R1 and the execution of reach display is defined as follows.

Next, the relationship between the extracted value of C RND R1 and the execution of reach display will be described. C RND
The determination of the execution of the reach display based on the extracted value of R1 is performed using a reach determination table described below.

FIG. 11 is an explanatory diagram showing the contents of the reach determination table. In the reach determination table shown in FIG. 11, the relationship between the extracted value of CRND R1 and the display content to be executed is predetermined for each gaming state.

The details are as follows. The playing state is
There are two types: normal time (when the reach probability improvement flag described later is not set) and when the reach probability improvement flag is set. Here, the reach probability improvement flag is a flag that is set when the control for improving the probability of executing the reach display (including normal reach, super reach 1, and super reach 2) is performed.

In the normal case, the relationship between the extracted value of C RND R1 and the display content is defined as follows. If the extracted value is “0”, execution of the reach display is determined. When the extracted value is "1" to "15", execution of normal display (display other than reach display) is determined.

When the reach probability improvement flag is set, the relationship between the extracted value of C RND R1 and the display content is defined as follows. Extracted value is "0" ~
If it is “7”, execution of reach display is determined. When the extracted value is "8" to "15", execution of normal display is determined.

As described above, in the reach determination table, when the reach probability improvement flag is set, the probability that the reach display is executed is set to be higher than that in the normal time when the reach probability improvement flag is not set.

Next, the specific contents of the reach probability improvement control will be described. The reach probability improvement control is executed in association with the execution of the main routine of the control program executed by the basic circuit 40 of the game control board shown in FIG.

FIG. 12 is a flowchart showing the control operation of the reach probability improvement control. Referring to FIG. 12, in step SA (hereinafter simply referred to as SA) 1, it is determined whether or not the reach probability improvement flag is set. If it is determined in SA1 that the reach probability improvement flag is set, the process proceeds to SA5 described later. on the other hand,
When it is determined in SA1 that the reach probability improvement flag is not set, the process proceeds to SA2.

At SA2, it is judged whether or not the predetermined period has expired. The predetermined period in this case is a period after the display of the last reach display (including all reach of normal reach, super reach 1 and super reach 2) is executed, and is predetermined. The detection of the passage of the predetermined period is started by the predetermined period detecting means in SA8 described later. Here, the predetermined period detection means,
Included in timer 56. The predetermined period detection means starts detection of the period when set and ends detection of the period when cleared.

If it is determined in SA2 that the predetermined period has not expired, the process proceeds to SA3 described later. On the other hand, if it is determined in SA2 that the predetermined period has expired, the process proceeds to SA4. In this way, if it is determined that the predetermined period has expired after the last reach display is executed, a process of setting the reach probability improvement flag is performed in SA4.

By the processing of SA4,
The reach probability improved state in which the probability of reach display is improved. After such processing of SA4 is performed, the processing of this routine ends.

When it is determined in SA1 that the reach probability improvement flag is set, the process proceeds to SA5, and it is determined whether or not the reach probability improvement state ending condition is satisfied. This termination condition is, for example, when a variable display (variable display) is performed a predetermined number of times after the reach probability improvement state has started. If it is determined in SA5 that the termination condition is satisfied, the operation proceeds to SA6, which will be described later. On the other hand, if it is determined in SA5 that the termination condition is not satisfied, the process proceeds to SA9, and it is determined whether or not the extracted value of CRND R1 is "0" to "7". In this case, since the reach probability improvement flag is set, the reach determination table of the portion corresponding to that state is referred to.

As described above, C RND R1 is for determining whether or not reach display is executed. In the reach probability improvement state in which the reach probability improvement flag is set, in the case of “0” to “7”, it is decided to execute the reach display. Therefore, this SA9
Then, it is determined whether or not the reach display is executed.
When it is determined in SA9 that C RND R1 is not "0" to "7" (when it is determined not to perform the reach display), this routine ends. On the other hand, SA9
When it is determined that C RND R1 is "0" to "7" (when it is determined to execute the reach display), the process proceeds to SA10. Then, in SA10, a process for performing reach display on the variable display device 4 is performed.
The type of reach executed in this case is the CR described above.
It is determined based on the value of ND R2. After the processing of SA10, the processing of this routine ends.

On the other hand, at SA6, which is executed when it is judged at SA5 that the termination condition is satisfied, processing for clearing the reach probability improvement flag that has been set is performed. This ends the reach probability improvement state. After the processing of SA6, the process proceeds to SA7. At SA7, processing for clearing the detection means for a predetermined period is performed. Then, the processing proceeds to SA8, in which processing for clearing the detection means for a predetermined period is performed. As a result, the detection of the elapse of the predetermined period is once ended. Then, the processing proceeds to SA8, in which the detection means is set for a predetermined period. As a result, the detection for the predetermined period is restarted. After SA8, the processing of this routine ends.

When it is determined by SA2 that the predetermined period has not expired, the process proceeds to SA3, and it is determined whether any type of reach display is made.
If it is determined in SA3 that the reach display is not made, the processing of this routine ends. On the other hand, if it is determined in SA3 that the reach display has been executed, the process proceeds to SA7 and the same process as the above-described process is performed. That is,
At SA7, the detecting means is cleared for a predetermined period, and at SA8,
The detection means is set for a predetermined period.

As described above, the clearing and setting of the detecting means for the predetermined period are performed when the reach display is made in a state where the reach probability improving flag is not set and when the reach probability improving flag is set in the end condition. When it is established, it is performed.

In the above description, when the ending condition of SA5, that is, the ending condition of the reach probability improved state is that the variable display (variable display) is performed a predetermined number of times after the start of the reach probability improved state. showed that. However, the end condition is not limited to this, and may be a case where the reach display is performed a predetermined number of times or a case where a predetermined time has elapsed after the start of the reach probability improvement state.

Further, in the above description, the case where the timer 56 is the predetermined period detecting means has been shown. That is, the predetermined period detected is a predetermined operating time of the gaming machine (time when there is a hit ball). However, the present invention is not limited to this, and the predetermined period to be detected may be a period in which the variable display (variable display) is performed a predetermined number of times. In this way, when the variable display of the predetermined number of times is detected, instead of the timer 56 described above,
The counter 55 is used.

The contents of the reach probability improvement control described above are summarized as follows. It is determined whether or not a predetermined period (a predetermined operating time or a predetermined number of times of variable display) has elapsed after the reach display is executed. Then, if the reach display is not executed within a predetermined period after the execution of the reach display, the probability that the reach display is executed is improved.

By performing such reach probability improvement control, the following effects can be obtained. When the reach display is not executed for a predetermined period, the probability that the reach is displayed is improved, so that the probability that the reach display is made becomes high. For this reason, it is possible to improve the interest without deteriorating the player's willingness to play.

In the above embodiments, the variable display device 4 is used.
Indicates an image display type. However, not limited to this,
