If the gaming machine has a gaming device that operates in the event that a specific condition is satisfied as a result of the operation of the gaming device, the gaming machine can be controlled to a gaming state advantageous to the player. It is possible.

FIG. 1 is a front view of a pachinko gaming machine 1 as an example of a gaming machine according to the present invention and a card unit 35 installed corresponding to the pachinko gaming machine.

The card unit 35 is provided with a card available indicator lamp 47, and the player is informed that the card unit 35 is ready for use by turning on or flashing the card available indicator lamp 47. Is done. The card unit 35 is installed in a state where it is inserted between a plurality of pachinko gaming machines 1 installed on the gaming machine installation island, and a connection stand direction is displayed to indicate which of the left and right gaming machines is connected. Is displayed by the container 49.

When a player inserts a so-called nationwide common card having a card balance recorded therein into the card insertion slot 50, the card balance recorded on the nationwide common card is read. Next, when the player performs a predetermined ball lending operation, the balance for the lending unit amount set in advance is reduced, and the ball for the lending unit amount is placed on the upper plate of the pachinko gaming machine 1. It is lent to 87.

The card unit 35 is provided with a fraction display switch 48. By pressing the fraction display switch 48, information such as a card balance and an error code when an error occurs is displayed on an information display (not shown) provided in the pachinko gaming machine 1. In the figure, reference numeral 51 denotes a card unit lock, which is configured so that the front side of the card unit 35 can be opened by inserting a predetermined key into the card unit lock 51 and performing an unlocking operation.

A game area 3 is formed on the game board of the pachinko gaming machine 1. The pachinko gaming machine 1 is provided with a hit ball operation handle 82 for a player to operate a hit ball. When the player operates the hit ball operation handle 82, the pachinko balls stored in the upper plate 87 are removed by one.
Can be fired individually. The fired pachinko balls are guided into the game area 3 between the section rails 2.

At the center of the game area 3, there is provided a variable display device 4 for variably starting a special symbol, which is an example of identification information, on the condition that a ball is hit into the starting port 9 for a winning prize. The variable display device 4 constitutes a game device that operates when a predetermined game condition is satisfied. Also,
The starting prize constitutes the game condition. If the display result of the variable display device 4 is a display result of a big hit symbol (for example, 777), a specific condition is satisfied and a big hit occurs. Further, below the variable display device 4, a variable winning ball device 10 is provided. The variable winning ball device 10 is attached by fixing the base plate 60 to the game board 3. Variable winning ball device 10
The first state, which is advantageous for a player who can win a ball when the solenoid 61a to be described later is energized, opens the opening and closing plate 61, and closes the opening and closing plate 61 when the solenoid 61a is demagnetized. It is configured to be able to change to a second state that is disadvantageous for a player who cannot make a hit ball to win. The variable winning prize ball device 10 is provided with six LEDs 62 that are lit or flashed according to the game state.

A warp entrance 21 is provided at each of the left and right portions of the variable display device 4.
The hit ball that has entered the warp entrance 21 is the variable display device 4
The water flows downward through the back side of the warp, and is discharged from the warp outlet 8 to the game area 3 again. For this reason, the ball discharged from the warp exit 8 is in a state where it is relatively easy to win the starting opening 9. A normal symbol starting gate 23 is provided on the passage of the ball hitting the warp entrance 21 provided on the left side of the variable display device 4. The ordinary symbol starting gate 23 has a passing ball detector 2 for detecting the passage of a ball.
3a is provided.

When a ball hit into the game area 3 normally enters the symbol starting gate 23, the passing ball is detected by the passing ball detector 23a, and a predetermined variable display condition is established. Thus, the normal symbol display 17 is variably started. The ordinary symbol display 17 constitutes a variable display device whose display state can be changed. Ordinary symbol display 1
If a passing ball is further detected by the passing ball detector 23a while the variable number 7 is starting to change, the passing ball is stored with the upper limit of "4", and the stored number is stored in the passing storage display 18
Will be displayed. The passing sphere detected by the passing sphere detector 23a when the stored number of passing spheres has reached the upper limit value “4” is invalidated without being used for variable display of a normal symbol.

The normal symbol display 17 is composed of, for example, a 7-segment display, and variably displays identification information called a normal symbol. If the display result of the normal symbol display 17 is in a predetermined special display mode (for example, 7), "hit" is obtained. When the display result of “hit” is derived on the ordinary symbol display 17, a pair of left and right movable pieces 20 provided in the starting port 9 is opened. As a result, the starting port 9 is in an open state, and the hit ball can be more easily started and won. If one of the hit balls wins while the starting port 9 is in the open state, the movable piece 20 closes to the original position and the hit ball returns to a state in which it is difficult to win. In addition, if a predetermined period has elapsed since the opening of the starting port 9, the movable piece 2 can be started even if the starting prize does not occur.
0 closes to the original position and the open state ends. The starting winning ball that has won the starting opening 9 is detected by a starting ball detector 9a described later, and based on the detection output, the variable display device 4 is detected.
Is variably started.

If a hit ball is started again in the starting port 9 and detected by the starting ball detector 9a while the variable display device 4 is variably displaying, the starting winning ball is stored and the variable display device 4 is variably stopped. After that, the variable display device 4 is again variably started based on the starting winning prize memory after the state in which the variable start can be started again. The upper limit of the start winning memory is set to, for example, "4". The start winning prize storage number at the present time is displayed by the start storage display 6.

The variable display device 4 comprises, for example, a CRT display 109 (see FIG. 4) capable of displaying a liquid crystal.
A variable display section 5 for displaying special symbols and other images is provided. The variable display section 5 can display a left symbol display area, a middle symbol display area, and a right symbol display area divided into three parts, and a special symbol is displayed in each symbol display area.
The special symbol displayed in the left symbol display area is called the left symbol,
The special symbol displayed in the middle symbol display area is called the middle symbol,
The special symbol displayed in the right symbol display area is called a right symbol.

When the variable display starts simultaneously in all the symbol display areas, a plurality of types of special symbols are scroll-displayed from top to bottom in the respective display areas. After that, when a predetermined time elapses, the left symbol is controlled to be stopped first, and then the right symbol is controlled to be stopped. When both the left symbol and the right symbol are controlled to be stopped when both stop symbols are the same type of big hit symbol, reach is established. When reach is established, the middle symbol is variably displayed in various display modes as compared with the case where reach is not established, and finally, the middle symbol is stopped and controlled.

When the special symbols in all the symbol display areas are variably stopped, and the result of the display of the big hit symbol is displayed, the opening and closing plate 61 of the variable prize ball device 10 is tilted to change the variable prize ball. The big winning opening of the device 10 is opened.
As a result, the variable winning ball device 10 is controlled to the first state, and the gaming state becomes a gaming state (specific gaming state) advantageous to the player.

The variable prize ball device 10 has a specific prize area, and a prize ball having won the specific prize area is detected by a specific sphere detector 61c described later. In addition, all the winning balls that have won in the variable winning ball device 10 are detected by the ball number detector 61b described later. In particular,
The specific ball detector 61c detects the specific winning ball detected by the specific ball detector 61c and the normal winning ball that has won a normal winning area other than the specific winning area. In the case where a predetermined number (for example, 9) of the hit balls that have entered the variable winning ball apparatus 10 in the first state are detected by the predetermined number (for example, 9) of ball number detectors 61b or when a predetermined period (for example, 30 seconds) has elapsed. When the earlier condition is satisfied, the first state of the variable prize ball device 10 ends and the state changes to the second state.
The number detected by the ball number detector 61b is displayed by a number display 63 composed of a 7-segment display. The hit ball that has entered during the period when the variable prize ball device 10 is in the first state makes a specific prize in the specific prize area, and after the variable prize ball device 10 enters the second state, the specific ball detector 6
If detected by 1c, the repetition continuation control for setting the variable winning ball device 10 to the first state again is executed. The upper limit number of executions of the repetition continuation control is set to, for example, 16 times. In the repetition continuation control, the variable winning ball device 10
Is referred to as a round.
When the maximum number of times of execution of the repetition continuation control is 16, the 16th round from the first round to the 16th round,
The variable winning ball device 10 can be brought to the first state.

In particular, when a big hit occurs due to a predetermined special symbol slot, the game mode is a probable change mode (also referred to as a high probability state or a probability variation state) in which the probability of occurrence of a big hit is high. A special symbol that changes the game mode to the probability variation mode is particularly called a probability variation symbol. It is promised that the probability change mode will continue until a big hit occurs twice after the big hit occurs in the positive change symbol. If a jackpot occurs in a probable pattern while the game mode is controlled to the probable mode, it is promised that the probable mode will continue until the big hit occurs twice after the big hit occurs.

In the gaming area 3 of the pachinko gaming machine 1, a windmill 19, ordinary winning openings 7, 11, 15 and
An out port 16 is provided for collecting an out ball if the hit ball does not win any of the winning areas or the variable winning ball devices. Out ball collected at the out port 16 is an out ball detector 153 described later (see FIG. 3).
Is detected by Further, the game board 3 is provided with a side lamp 22 for displaying a decorative pattern. Speakers 81 for generating sound effects such as stereo sound are provided on the left and right of the upper part of the game board 3. Reference numeral 83 in the figure denotes a key for preventing the front frame, which is the frame on the front side of the pachinko gaming machine 1, from being opened and closed.

When a hit ball wins in various winning areas such as the starting port 9, the variable winning ball device 10, and the normal winning ports 7, 11, and 15, a predetermined number of prize balls corresponding to the winning port are placed on the upper plate 87.
Paid out. Below the upper plate 87, there is provided a lower plate 86 for storing hit balls discharged from the upper plate 87 by operating the upper plate pulling lever 84. The hit balls stored in the lower plate 86 can be discharged to a ball box or the like prepared below the lower plate lever 85 by operating the lower lever 85. The player can obtain a game profit by acquiring a prize ball which is an example of a game result value obtained as a result of the game. In particular, if a big hit occurs frequently, the player can benefit from the specific game state and can obtain more game profit.

On the other hand, in the case where the frequency of occurrence of the start winning is low even though the game is played continuously for a long time, the disadvantage in the game becomes large. Profit decreases quickly. For this reason, the disadvantageous amount of the player becomes excessively large, and the player's willingness to play eventually decreases.

Therefore, the pachinko gaming machine 1 monitors whether or not the frequency of occurrence of the start winning prize every time the number of shot balls fired by the player in the game area 3 reaches a predetermined number is not too low. Function is provided. If the start winning frequency is too low, the game mode is changed from the normal mode to the shortened mode in order to optimize the starting winning frequency. By changing the game mode to the shortening mode, the fluctuation time of the ordinary symbol (variable display time) is shortened, and the opening time of the starting port 9 opened based on the occurrence of the "hit" is lengthened. Note that the variable time (variable display time) refers to the time from the start of variable display of a normal symbol on the normal symbol display 17 until the display result is derived and displayed.

By reducing the fluctuation time of the normal symbol, the number of times that the display result of the normal symbol can be derived and displayed per unit time increases. As a result, it is determined at an early stage whether or not a “hit” occurs as a result of displaying the change of the ordinary symbol. If the result of the "hit" is determined early, the opening time of the starting port 9 is moved forward so much, and a state in which the starting prize can be easily won comes soon. As a result, the start winning frequency is increased. In addition, it is possible to minimize the occurrence of passing balls that become invalid because the storage of passing balls displayed on the passing memory display 18 is successively digested at a rapid tempo by shortening the fluctuation time of the symbol. Can be prevented. As a result, more passing balls can be effectively used for the variable display of the ordinary symbol, and the chance of the ordinary symbol becoming a "hit" can be increased. If more “hits” occur, the chances of opening the starting port 9 increase, and as a result, the starting winning frequency increases. Furthermore, if the opening time of the starting port 9 that is opened due to the occurrence of the "hit" is lengthened, the state in which the starting prize is easy to be continued for a longer time, and as a result, the frequency of starting prize is increased.

Therefore, when the game mode is changed to the shortening mode, the start winning frequency is increased. This ensures that the player's penalty is not excessive,
It is possible to prevent the ejaculation of the game from becoming too high due to the extreme variation in the start winning frequency, and to prevent the player's willingness to play the game. Also,
Unfairness can be prevented from occurring with a player playing a game on a gaming machine in which a start winning is generated at a predetermined appropriate frequency.

FIG. 5 is a diagram showing a comparison table in which the fluctuation time of a normal symbol, the probability per normal symbol, the opening time of the starting port 9 and the like are compared for each game mode. The “shortening mode” selected when the start winning frequency is determined to be extremely low in the pachinko gaming machine 1 has a hit probability of 1/5 as compared to the “normal mode”, and has the same probability. . However, in the “shortening mode”, the fluctuation time of the ordinary symbol is set to be extremely short as compared with the “normal mode”, and the opening time of the starting port 9 is set to be extremely long. Specifically, while the fluctuation time of the ordinary symbol is set to 28 seconds in the “normal mode”,
In the "shortening mode", the time is set to 5.5 seconds which is less than 20%. On the other hand, regarding the opening time of the starting port 9,
In the "normal mode", it is set to 0.5 seconds, whereas in the "shortening mode", it is set to 3.5 seconds, which is seven times that. For this reason, in the “abbreviated mode”, the hit probability itself is the same as the “normal mode”, but the “normal mode”
Start winning frequency is higher than that of.

The setting of the “probable change mode” is different from that of the “shortening mode” in that the hit probability is set to 4/5. For this reason, the start winning frequency is even higher than in the “shortening mode”. Note that the count is the number of times a start winning is permitted when the start port 9 is in the open state.
The number of times is the same in each game mode and is set to one time. Accordingly, the open state ends on condition that one starting ball is hit in the open opening 9.

Next, winning ball signal processing is performed (S16). In the prize ball signal processing, processing is performed to execute payout of a prize ball according to the detection of a prize ball.

Next, it is determined whether or not the game is in the normal game state (S17). The normal game state means a state in which the game mode is set to a normal mode other than the shortening mode and the probability change mode. When the normal mode is set, the number of fired balls is managed (S18), and the S stabilization process (S19) is performed in order to determine whether or not the start winning frequency is abnormally reduced. Are respectively executed. The details of the launch ball number management process will be described later with reference to FIG. 7, and the details of the S stabilization process will be described later with reference to FIG.
On the other hand, if it is determined in S17 that the game mode is set to the certainty change mode other than the normal mode or the shortened mode, it is not considered that the start winning frequency is abnormally reduced, so that S18 and S19 are performed. Are not executed.

After the S stabilization process is executed in S19, or when it is determined in S17 that the game mode is set to a mode other than the normal mode, a display similar to that in S15 is displayed until a predetermined interruption is performed. The random number updating process is repeatedly executed (S20). Next, with reference to FIG. 7, the content of the shooting ball number management process executed in S18 will be described. The launched ball count management process is a process of comparing the number of launched balls launched into the game area 3 with the number of outgoing balls collected at the out opening 16 and notifying an error when an abnormality has occurred. . First, it is determined whether the launching ball detector (launching ball SW) 151 is turned on and a launching ball is detected (SA).
1). When a shooting ball is detected, the firing stop timer for measuring the time during which the shooting ball is not detected is cleared (SA2), and the counter value of the shooting ball counter for counting the number of shooting balls is added. Updated (+1) (SA3). Note that the firing stop timer is set in the RAM 200d
Is stored in

After SA3, or when no shooting ball is detected in SA1, the foul ball detector (foul ball SW) 152 is turned on to determine whether or not a foul ball has been detected (SA4). ). If a foul ball is detected, the count value of the shooting ball counting counter is decremented and updated (-1) (SA5). Foul ball is a game area 3
Is not reached, and is returned to the player.

After SA5 or when no foul ball is detected in SA4, the out ball detector (out ball SW) 153 is turned on to determine whether or not an out ball is detected (SA6). ). When an out ball is detected, the out ball counter is incremented and updated (+1) (SA10). Then, it is determined whether or not the difference between the count value of the shooting ball counter and the count value of the out ball count counter does not exceed 10 (SA11). When the difference number exceeds 10, a NO determination is made in SA11 and an error generation process is executed (SA14). By executing the error generation processing, a notification sound is output from the speaker 81 for at least a predetermined time and the game control is interrupted. On the other hand, if the difference between the count value of the firing ball counter and the count value of the out ball count counter does not exceed 10, it is determined whether or not both count values match (SA1).
2). If the two count values do not match, the process ends. If they match, the firing ball counter and the out ball counter are both cleared (SA13), and then the process ends. By clearing the fired ball counting counter and the outgoing ball counting counter on the condition that the two counting values match, it is possible to prevent the counter values of both counters from increasing without limit.

If no out ball is detected in SA6, the firing stop detection timer is incremented and updated (+1) (SA).
7). Then, the timer value of the firing stop detection timer is 300
It is determined whether the value exceeds seconds (SA
8). If the timer value of the firing stop detection timer does not exceed 300 seconds, the process ends.
If the value exceeds two seconds, both the firing ball counting counter and the out ball counting counter are cleared (SA
9). The firing stop timer is cleared at any time in SA2 as long as a firing ball is detected. If the timer value of the firing stop timer is longer than 300 seconds, the firing ball is not hit. For 5 minutes. Therefore, in this case, it is considered that the game has been stopped, and the firing ball counter and the out ball counter are cleared once to eliminate the accumulation of errors.

Next, the contents of the S stabilization processing executed in S19 will be described with reference to FIG. The S stabilization process is a process of changing the game mode according to the start winning frequency. Note that S is an abbreviation that means a variable display count per unit time based on a winning start. Prior to the description of each step of the flowchart, an outline of the S stabilization processing will be described below.

In the S stabilizing process, the starting winning frequency is determined each time the player has finished firing 25 pachinko balls. The feature of the S stabilization processing is that the starting winning frequency is not determined based on the number of starting winnings that occurred during the period when the pachinko ball was fired 25 times, but the starting ball was reversed from the firing ball of the 25th shot in the past. In other words, the starting winning frequency is determined based on the number of starting winnings generated during a period in which a total of 100 pachinko balls are fired. Therefore, the start winning frequency can be finely determined in a short cycle (every 25 shooting balls), but is averaged based on the starting winning occurrence situation for a longer period (a period in which 100 firing balls are detected). The start winning frequency can be determined from the obtained data.

To make such processing feasible,
A starting opening winning counter 1 to a starting opening winning counter 4 capable of storing the number of starting winnings each time the number of shot balls reaches 25 are used, and each of the starting opening winning counter 1 to the starting opening winning counter 4 is used. The start winning number per 100 shot balls (25 shots × 4) is specified by the total value. After the processing for determining the start winning frequency based on the total value of the starting opening winning counter 1 to the starting opening winning counter 4 is performed, the counter value of the starting opening winning counter 3 is prepared for the next determination processing. Is rewritten as the counter value of the starting opening winning counter 4, the counter value of the starting opening winning counter 2 is rewritten as the counter value of the starting opening winning counter 3, and finally, the counter value of the starting opening winning counter 1 is changed to the starting opening winning. It is rewritten as the counter value of the counter 2 and the shift processing is performed. Thereafter, the counter value of the starting opening winning counter 1 is cleared. Then, the counting of the number of start winnings is restarted by the starting opening winning counter 1.

The contents of the S stabilization process will be described below with reference to the flowchart. First, a launch sphere detector (launch sphere S
W) It is determined whether or not 151 is turned on and a shooting sphere is detected (SB1). If a launch sphere is detected,
The counter value of the firing monitoring counter for counting the number of fired balls is added and updated (+1) (SB2). The firing monitoring counter is stored in the RAM 200d as described above. After SB2 or when no launch ball is detected in SB1, the ball detector 152 is turned on to determine whether or not a ball is detected (SB).
3). If a foul ball is detected, the counter value of the firing monitoring counter is decremented and updated (−1) (SB
4). After SB4 or when no ball is detected in SB3, the starting ball detector (starting SW) 9a is turned on to determine whether or not a winning start is detected (SB5). When the start winning is detected, the start opening winning counter 1 for counting the number of the detected start winning is incremented and updated (+1) (SB6). in this way,
The counting of the number of starting winnings is performed only by the starting opening winning counter 1 among the starting opening winning counters 1 to 4. The starting opening winning counter 1 and the starting opening winning counter 4 are stored in the RAM 20 together with the starting opening winning counter 2.
0d.

After SB6 or when no winning start is detected in SB5, it is determined whether or not the count value of the firing monitoring counter is still less than 25 (SB)
7). If it is less than 25, the process ends because it is not yet time to determine the start winning frequency. On the other hand, when the counter value of the firing monitoring counter has reached 25, it is time to determine the start winning frequency, and the following SB8 to SB8
The process of SB13 is executed. Here, since the determination time for determining the start winning frequency using the counter value of the firing monitoring counter is specified, it is not necessary to separately provide a timer for determining the determination time.

First, at SB8, the starting opening winning counter 1
The total value of each of the starting opening winning counters 4 is calculated. As described above, the start opening prize counter 2 to the start opening prize counter 4 indicate that the number of the start winning prize that occurred during the period in which the hit ball of “25 × 3” was fired in the past was shot up to 25 shots. It is stored for each ball firing period. Therefore, by calculating the total value of each of the starting opening winning counter 1 to the starting opening winning counter 4, the total is 1
The number of start winnings generated during the period in which 00 pachinko balls are fired is specified.

Next, it is determined whether or not the total value is less than 5 (SB9). If the total value is less than 5, it is considered that the starting winning frequency is lower than a predetermined appropriate frequency, and 1 is set to the shortening mode flag (SB1).
0). By setting 1 to the shortening mode flag, the game mode changes to the shortening mode. This allows
It can be expected that the start winning frequency will increase. When the current game mode is in the probability change mode, that is, when 1 is set in the probability change mode flag, the definition of the probability change mode flag has priority. Therefore, even if the shortening mode flag is set to 1 here, the probability change mode does not change to the shortening mode. On the other hand, if the total value of each of the starting opening winning counter 1 to the starting opening winning counter 4 is 5 or more, a negative determination is made in SB9 and the shortening mode flag is cleared (= 0) (SB11).

After the processing of SB10 or SB11, the counter values of the starting opening winning counter 1, the starting opening winning counter 2, and the starting opening winning counter 3 are respectively set to the starting opening winning counter 2, the starting opening winning counter 3, and the starting opening winning counter. 4 is performed (SB1).
2). Next, in order to prepare for the counting of a newly generated start winning, after the counter value of the starting opening winning counter 1 is cleared (SB13), the processing is ended.

In the above S stabilization processing, a total of 10
Since the number of start winnings generated during the period in which zero pachinko balls are fired is distributed and stored in the starting opening winning counter 1 to the starting opening winning counter 4, a single counter has a total of 100 pachinko balls. It is possible to design with a smaller storage area required for each of the opening prize counters 1 to 4 than when storing the number of starting prizes generated during the period in which the ball is fired.

Next, modifications and features of the above-described embodiment will be enumerated below. (1) When the start winning frequency is higher than a predetermined appropriate frequency, a process for optimizing the starting winning frequency may be performed. For example, at the upper part of the starting opening 9, an obstructing member capable of obstructing the hitting of the ball into the starting opening 9 is provided so as to be able to come and go. It is conceivable that the system is configured to be in a state in which it is difficult for the start winning. If the start winning frequency is higher than the appropriate frequency, the movable piece 20 is further closed than in the normal mode, and the hit ball changes to a state in which the start winning cannot be achieved. May be configured to be repeatedly performed.

(2) The start winning frequency is calculated based on the number of detections of the starting ball detector (start SW) 9a. However, based on only the effective start winning used effectively for the variable display of the variable display device 4, The start winning frequency may be calculated. In this case, the frequency at which the variable display is performed by the variable display device 4 is almost the same as that calculated.

(3) The determination of the frequency of establishment of the start winning is made based on the period in which the last 100 shot balls were detected, based on whether or not five or more starting winnings have occurred during that period. However, instead of this, the rate of occurrence of the start winning is calculated from the number of shot balls counted from the time when the power of the pachinko gaming machine 1 is turned on to the present and the number of times of starting winning, and the occurrence rate is determined to be an appropriate predetermined rate. It may be determined whether there is a large difference from the rate.

(4) In this embodiment, the so-called first-type pachinko gaming machine 1 has been described as an example of the gaming machine. However, the present invention is also applicable to the following types of pachinko gaming machines.

That is, there is a variable winning ball device that can be changed between a first state in which a hit ball can be won and a second state in which a hit ball cannot be won. When the variable winning prize ball device changes from the second state to the first state when a ball is won at the specific winning opening, a specific operation of again setting the second state is performed, and the ball is in the first state. When a ball is hit in a specific area of the variable winning ball device, the variable winning ball device is temporarily changed to the second state, and then is repeatedly and continuously controlled to the first state and the second state again. In a gaming machine in which continuation control is performed, the display result of the variable display device is derived and displayed on condition that the hit ball has passed a predetermined passband, and when the display result is a result of "hit", The movable piece provided in the specific winning opening is opened greatly for a predetermined time. Winning opening is controlled to obtain easily open the winning of hitting ball, a second type of pachinko machine.

In such a second type of pachinko gaming machine, if the frequency of hitting a ball at a specific winning opening (or the frequency of performing the specific operation) is not appropriate, the fluctuation time of the variable display device is shortened (extended). ) Or by increasing (shorting) the opening time of the specific winning opening, thereby adjusting the frequency of hitting the ball at the specific winning opening (or the frequency of performing the specific operation). can do.

In other words, the second type of pachinko gaming machine has a game machine that operates when a predetermined game condition is satisfied, and when the specific condition is satisfied as a result of the operation of the game device, the player can play the game. A gaming machine that can be controlled to an advantageous gaming state is configured. The predetermined game condition is constituted by a hit ball winning the specific winning opening. The variable winning prize ball device constitutes a game device that operates when the predetermined game condition is satisfied. As a result of the specific operation being performed by the variable winning ball device based on the fact that the hit ball has won the specific winning opening, the specific condition is configured such that the hit ball wins a specific area of the variable winning ball device. Have been. Depending on the gaming state in which repeated continuation control based on winning of a hit ball to a specific area is performed,
A game state advantageous to the player is configured.

(5) The S stabilization process of FIG. 8 can be modified as follows. In other words, the starting opening winning counter is constituted by one counter, and the counter value is added and updated as needed based on the occurrence of the starting winning. Then, when the counter value of the firing monitoring counter reaches 100, the counter value of the starting opening winning counter is determined, and if the value is less than 5, the shortening mode flag is set to 1. Thereafter, the start port winning counter and the firing monitoring counter are reset.

Even in the case of the above configuration, the start winning frequency can be determined based on the number of start winnings generated during the period in which the number of shot balls 100 is counted, as in the S stabilization processing of FIG. . However, the discrimination period becomes longer (four times) as compared with the S stabilization process in FIG. 8, so that the game mode cannot be flexibly changed in response to the ever-changing change in the start winning frequency. There is. Further, the storage capacity required for one start opening winning counter becomes large. From this point of view, the S stabilization process shown in FIG. 8 can solve problems that can occur in this type of modification.

(6) The embodiments disclosed this time are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

[0088]

The effect of the concrete example of the means for solving the problems.
When the game condition for operating the gaming device is not satisfied at a predetermined frequency, the number of times that the display result of the variable display device can be derived and displayed per unit time changes and the gaming Since the frequency of establishment of the condition is adjusted, the frequency of establishment of the game condition is adjusted to an appropriate frequency according to the actual game situation. Therefore, it is possible to prevent the frequency of establishment of the gaming condition from being extremely varied depending on the gaming machine. As a result, it is possible to prevent the occurrence of inconvenience, such as an extremely high shootability of the game.

According to the second aspect, in addition to the effect of the first aspect, when the frequency of establishment of the game condition is lower than the predetermined frequency, the frequency of establishment of the game condition is adjusted. Is extremely low, it is possible to prevent the player from suffering excessive disadvantage in the game.

According to the third aspect, in addition to the effect of the first or second aspect, since the timing for performing the determination is determined using the count result of the hit ball number counting means, the determination is performed. There is no need to provide a dedicated timer or the like for determining the timing, and the storage capacity required for control can be reduced accordingly.

According to the fourth aspect, in addition to the effect of the third aspect, the discrimination is performed every time a predetermined number of balls are counted by the number of hits counting means. Since the determination period extends over a past period including the period in which the predetermined number of hit balls are counted, the frequency of establishment of the game condition can be determined in a short cycle, but the game condition of a longer period can be determined. The establishment frequency of the game condition can be determined based on the averaged data based on the establishment status.

According to the fifth aspect, in addition to the effect of the third aspect, the number of times that the game condition is satisfied during the determination period is determined by the first and second establishment number storage means. Since the number of times that the game condition is satisfied is stored in the single storage unit without dispersing the number of times the game condition is satisfied during the determination period, the number of times that the game condition is satisfied is stored in a single storage unit. The storage capacity required for the means can be reduced.
