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 scheduled stop symbol to be displayed when the left, middle, and right variable display portions of the variable display device 4 when it is predetermined to be 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 for determining whether or not the reach display is performed. After counting up from 0 and counting up to 15 which is the upper limit thereof, it is counted 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 decided 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 to generate a big hit 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 these three scheduled stop symbols are decided, the decision contents are, for example, a doublet and the combination of symbols for generating a big hit happens to coincide with each other, and the extracted value of CRND ZU2 is "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 diagram 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 C RND 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, 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}. In other words, if the design changes 4500 times (variable display is performed), a 6-time big hit will appear in normal reach. 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)}.
× {Probability that the reach display is determined by C RND R1 (see FIG. 4)} × {Probability that the deviation is determined by C RND1 (see FIG. 4)} In case of normal reach, the appearance rate is {17/20} ×
{1/16} × {224/225} = {238/450
0 °. 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.

The expectation (%) of the jackpot is "2.5%" in the normal reach, "20.0%" in the super reach 1, and "33.3 in the 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, referring 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 is started. 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 section, 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 performs display control in the variable state A for 6.990 seconds after starting the variable display, and then displays the variable display in the variable 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.

Thus, in this gaming machine, it is possible to display, for example, two types of super reach, 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 gaming machine, super reach 1
Alternatively, when the super reach 2 is not displayed for a predetermined period, the super reach 1 or the super reach 2 is forcibly displayed on the variable display device 4. Hereinafter, the contents of the super reach forced display processing for forcibly displaying the super reach will be described. This super-reach compulsory display processing 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 super reach forced display processing. 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 CRND R1 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 that the jackpot is a big hit in S2,
Proceed to S3, the jackpot flag is set, and then proceed to S5, 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 S3, and 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 the big hit, the process proceeds to S4, and it is determined whether or not the reach display is performed. If it is determined that the reach display is not made in S4, this routine ends. On the other hand, S
When it is determined that the reach display is performed in step 4, S5
Proceed to.

In S5, C RND R2, which is a random number for determining the reach type, is referred to. As a result, the determined reach type is determined.

Next, in S6, as a result of the reference in S5, it is judged whether or not the type of reach is super reach (either super reach 1 or super reach 2). If it is determined in S6 that the type of reach is super reach, the process proceeds to S11 described later. on the other hand,
When it is determined in S6 that the type of reach is not super reach, the process proceeds to S7, and it is determined whether or not the predetermined period has expired for each of super reach 1 and super reach 2.

The predetermined period in this case is a period after the previous display of each of Super Reach 1 and Super Reach 2 is executed, and is predetermined. Detection of elapse of a predetermined period corresponding to each super reach is performed in S12 described later.
At, the detection is started by the predetermined period detecting means provided corresponding to each of the super reach 1 and the super reach 2. Here, the predetermined period detection means is the timer 5
Included in 6, Super Reach 1 and Super Reach 2
A timer for detecting a predetermined period provided corresponding to each of the above. Each of the predetermined period detection means for each type of super-reach starts detection of the period when set, and ends detection of the period when cleared.

If it is determined in S7 that the predetermined period has not expired, the processing of this routine ends. On the other hand, S
When it is determined in 7 that the predetermined period has expired, the process proceeds to S8. In this way, if it is determined that the predetermined period has expired after the previous display of Super Reach 1 or the display of Super Reach 2, the display of Super Reach 1 or Super Reach 2 is changed as follows. Execution is forced.

At S8, it is determined whether the type of super reach for which the predetermined period has expired is super reach 1. If it is determined in S8 that the type of super reach for which the predetermined period has expired is super reach 1, S9
Then, the processing for forcibly executing the display of the super reach 1 is performed. On the other hand, if it is determined in S8 that the type of super-reach for which the predetermined period has expired is not super-reach 1 (that is, if it is super-reach 2), S
Proceeding to 10, the processing for forcibly executing the display of the super reach 2 is performed. After such processing of S9 or S10 is performed, the step proceeds to S11.

As described above, in S8, S9, and S10, the super reach in which the predetermined period has expired is forcibly executed. In the present embodiment, the execution timing of the display of the super-reach executed in S9 or S10 is set to the time of the reach display of that time after it is decided to perform the forced display of the super-reach. It may be the next variable display or the next reach display.

In S11, a process for clearing the detecting means for a predetermined period corresponding to the super reach (1 or 2) for which the display is executed is performed. As a result, the detection of the elapse of the predetermined period is once terminated. After that, in S12, a process of setting the detection means for a predetermined period corresponding to the displayed super reach (1 or 2) is performed. As a result, the detection for the predetermined period is restarted. After S12, the processing of this routine ends.

In the above description, the case where the timer 56 is the predetermined period detecting means has been shown. That is, the detected predetermined period is a predetermined operating time of the gaming machine. 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 or a period in which the reach display is performed a predetermined number of times. Good. When detecting the variable display a predetermined number of times or the reach display a predetermined number of times in this way, the counter 55 is used instead of the timer 56 described above. In that case,
The counter 55 includes a counter for detecting a predetermined period (predetermined number of times) corresponding to each of the super reach 1 and the super reach 2.

The predetermined period detected by the predetermined period detection means in the super-reach forced display process is the time during which one player plays a game with one gaming machine and the jackpot expectation at the time of appearance of the super-reach. It is set in consideration of not lowering too much. A specific example of such a predetermined period is as follows. When the predetermined period is determined by the operating time, the predetermined period is about 1 to 2 hours. If the predetermined period is defined by the variable display count, the predetermined period is 200
Approximately 400 times (however, the appropriate value varies depending on the jackpot probability, the starting winning rate, etc.). When the predetermined period is determined by the number of reach displays, the predetermined period is about 20 to 40 times (however, the appropriate value changes depending on the reach occurrence rate).

The contents of the super-reach compulsory display processing described above are summarized as follows. For each of the super reach 1 and the super reach 2, it is determined whether or not a predetermined period (a predetermined operating time, a predetermined number of variable display times, or a predetermined number of reach display times) has elapsed after execution. Then, for each of the super-reach 1 and the super-reach 2, if the display of the corresponding super-reach is not executed again within the predetermined period after the execution, the display of the corresponding super-reach is forcibly executed.

The following effects can be obtained by carrying out such processing of forced super-reach display.
If Super Reach 1 or Super Reach 2 is not executed for a predetermined period of time, the display of the Super Reach that has not been executed for a predetermined period of time is forcibly executed, so if you play the game for a predetermined period of time, it will be a big hit at least once. Since a super-reach state (special reach state) with a high ratio appears, it is possible to improve the enjoyment without deteriorating the player's willingness to play. Further, the forced reach display causes the super reach to be displayed at least every predetermined period, so that the image information prepared in advance for displaying on the variable display device 4 is not wasted sufficiently. Can be utilized.

In this embodiment, there are three types of reach, but there may be two types or four or more types. Further, in the present embodiment, both of the super-reach 1 and the super-reach 2 are targeted for the super-reach compulsory display, but the super-reach compulsory display processing may be performed on only one of them.

In the above embodiments, the variable display device 4 is of the image display type. However, the present invention is not limited to this, and the variable display device may be a mechanical device as described below. That is, the rotating drum type, the display state changes as the belt with a plurality of symbols circulates. The so-called belt type, the leaf type, the display state changes with a rotating disc with a plurality of symbols rotating. It may be a so-called disc type or the like.
