DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a symbol change display, such as a color liquid crystal display, provided on a game board. The present invention relates to a pachinko gaming machine which is configured to be in an open state so that a hit ball is very easy to win.

[0002]

2. Description of the Related Art As is well known, a first-class pachinko game machine called a "fever machine" is provided with a pattern variation display such as a color liquid crystal display and a CRT on a game board, and is hit by a player. When the hit ball enters the tulip-type starting port, a plurality of rows (usually three rows) are displayed on the symbol variation display so that the numbers 1 to 8 and symbols such as ☆ ◆ ◎ or symbols or characters, etc., flow vertically or horizontally. ), The display is stopped in order after a few seconds, and the stopped symbol has a predetermined probability (approximately 1/251) with chance, for example, “22”.
2), "777", "☆☆☆", etc., when the same pattern is displayed in each row, a jackpot is won, and the opening and closing door of the variable winning device (large winning opening) is opened by the operation of the solenoid. The so-called first round ends when a predetermined number (usually 10) of hit balls hits the variable winning device in the opened state or when a predetermined time limit (usually 30 seconds) elapses in the opened state. The variable winning device is closed once, but if a hit ball has been hit into a continuous winning opening (referred to as a V zone) provided in the variable winning device during the first round, the variable winning device is closed. Immediately after the start of the second round, the variable winning device is opened again, and a predetermined number (usually 10) of hit balls are hit into the opened variable winning device, or a predetermined time limit (normally). 30 seconds), the second When the round is over, the variable prize device is closed again. However, if a ball is hit in the continuous prize hole during the second round, the third round starts and the variable prize device is opened again immediately. In this way, the variable winning device is continuously opened until the final round (for example, the 16th round), provided that a hit ball has been won in the continuous winning opening during each round. During such a jackpot process, the variable winning device is opened. In such a situation, it is possible to obtain a large number of prize balls and to bring many benefits to the player since the situation where the ball is extremely easy to hit is continued.

[0003]

In this type of pachinko game machine, the probability of generating a jackpot is constant except for some models (provided with a probability change key). When the field tried to adjust the so-called "balls" for its management, it had to adjust the nails to make it easier or harder to enter the starting opening. But,
Even if you make it easy to enter the starting opening by adjusting the nail, the jackpot does not always occur, so the "ball out" is not always good, and conversely, even if you make it difficult to enter the starting hole, the "ball out" is not always bad It was not always the case, and in many cases it was not the result of speculation in the amusement arcade.

[0004] Therefore, the present invention is to provide a pachinko game machine in which the probability of occurrence of a big hit is changed and controlled based on the frequency of winning in the starting opening, and it is easy to obtain the intended result of the game hall with respect to payout. Is what you do.

[0005]

And a solenoid 24 of the variable winning device 7 and a solenoid 25 for opening and closing the blade 6 of the starting port 5 are connected.

Next, the operation of the pachinko gaming machine will be described with reference to the flowchart of FIG. In this pachinko gaming machine, various initializations are performed by turning on the power, at the same time, the probability of occurrence of a big hit is set to 1/300 in step a, and the winning storage number of the winning number counter is set to 0 in step b. You. And step c
When the start switch 21 detects that a hit ball has hit the starting opening 5 by the starting switch 21 and the starting conditions are satisfied, the process proceeds to step d, and if the measuring time (set to 10 minutes here) timer has already expired, the process proceeds to step d. n, otherwise to step e. In step e, the process proceeds to step o or step f depending on whether or not the measured time timer is operating. In step o, it is determined whether or not the winning in the starting port 5 is within one minute from the previous winning. If it is less than one minute, the specific time timer is cleared in step p and the process goes to step g. If it is not less than one minute, the number of measurement storage units is reduced by going through steps q, r and s. Initialization is performed, and the measurement time timer and the specific time timer are cleared.
At step f, the measurement time timer is started to operate, at step g, a specific time (here, set to one minute) timer is started, and at step h, the winning storage number is set to 1
It is determined in step i whether or not the measurement time has elapsed, and if not, the process returns to step c and the number of winnings to the starting port 5 is continuously measured. When the predetermined measurement time has elapsed, the process proceeds to steps j and k, where the operation of the measurement time timer is terminated, and the operation of the specific time timer is terminated.

Then, it is determined in step 1 whether or not the number of winning storages is equal to or greater than a predetermined number (here, 75). If the number is greater than or equal to the predetermined number, in step m, the jackpot occurrence probability is set to 1/250, and step n At symbol fluctuation display 2
, Symbols such as 1 to 8 and symbols such as 図 and 図, or symbols and other symbols are displayed in three columns in a variably flowing manner from top to bottom. The fluctuation is, for example, “222”, “77”
When a stop is made at a specific symbol such as “7” or “☆☆☆”, a big hit occurs, and the opening and closing door of the variable winning device 7 is continuously opened by the operation of the solenoid 24, and further to the continuous winning opening 9. By repeatedly opening the variable winning device 7 until the 16th round under the condition of winning, a large number of hit balls can win during this jackpot processing.

If the prize to the starting port 5 is interrupted for a specific time during the above measurement time, the player shifts from step o to steps q, r, and s so that the player can play the pachinko game machine for a short time. In the case where the stop is made, the data does not become the measurement data, and thereafter, the winning number is measured and stored again from the time when the winning in the starting port 5 is detected again, and the big hit is generated based on the stored number. The probability is controlled to change.

In this embodiment, when 75 or more prizes are won in the starting port 5 within 10 minutes, the jackpot occurrence probability increases from the normal probability (1/300) to the high probability (1/250). In addition to winning the prize, the jackpot is more likely to occur. For this reason, if the nail is adjusted to make it easier to enter the starting opening, it is possible to more reliably improve the "outgoing", and conversely, if it is difficult to enter the starting opening, the "outgoing" is more reliably made to be worse. Can be obtained, and the result intended by the game arcade can be easily obtained.

On the other hand, if the number of winnings to the starting port 5 in 10 minutes is 75 or more, the jackpot occurrence probability is changed from the normal probability (1/300) to the low probability (1/350).
It is also possible to set to lower. In such a case, the probability that a jackpot occurs on a stand that is easy to enter into the starting port is reduced, so that it is possible to average the “payout” of each stand.

[0013] It is also possible to control the change of the probability more finely in accordance with the number of winnings in the starting opening.
The probability may be changed not only once but also at any time, for example, every time the big hit operation is completed. Further, the probabilities before and after the change may be set in advance by a setting key (not shown) or the like according to the intention of the game arcade.

Next, an embodiment of the present invention will be described. In this pachinko gaming machine, as shown in the block diagram of FIG. 4, the shot ball detection means 26 is connected to the game control board 15. This shot ball detection means 26
Is provided with a detection switch (not shown) at the tip of a firing rail 13 provided on the game board 1 shown in FIG. 1 to detect a hit ball fired in a game area of the game board.

In this pachinko gaming machine, as shown in the flow chart of FIG. 5, various initializations are performed upon turning on the power, and at the same time, the probability of occurrence of a big hit is set to 1/300 in step A, and Then, the winning storage number of the winning number counter is set to 0, and the number of hit balls is set to 0 in step C. When the hit ball is detected by the hit ball detecting means 26 in step D, step E,
Move to F, G, H, and in Step I, the number of hit balls
In step J, the presence or absence of a prize in the starting opening is detected, and 1 is added to the prize storage number. Then, at step L, it is determined whether or not the measurement time has elapsed. If not, the process returns to step D. When the predetermined measurement time has elapsed, the process proceeds to steps M and N, where the operation of the measurement time timer is terminated, and the operation of the specific time timer is terminated.

In step O, the number of winning storages / the number of hit balls is 0.075 or more (that is, the winning probability is 7.5).
% Is determined, and if it is, the jackpot occurrence probability is set to 1/250 in step P, and the process proceeds to step Q to start the fluctuation of the symbol fluctuation display 2, and the specific symbol is displayed. Generate a jackpot if stopped.

Steps R to W are performed when the player stops playing the pachinko game machine in a short time and the detection of the hit ball is interrupted for a specific time during the measurement time. After that, if the number of hit balls is detected continuously again, the number of winning storages and the number of hit balls are measured again from that point.

In this embodiment, if the winning probability to the starting port 5 in the measurement time of 10 minutes is 7.5% or more, the jackpot occurrence probability is changed from the normal probability (1/300) to the high probability (1/250). ) To rise. For this reason, in addition to the winning opening 5 being easy to win, the jackpot is more likely to occur, and the "adjusted ball" can be more reliably improved by the nail adjustment, and conversely, if it is difficult to enter the starting opening, It is possible to surely make the "outgoing ball" worse, and it is easier to obtain the result intended by the game hall.

Of course, in this embodiment as well, when the winning probability to the starting port 5 in the measurement time of 10 minutes is 7.5% or more, the jackpot occurrence probability is changed from the normal probability (1/300) to the low probability (1/300). 350).

In this embodiment, the winning storage number /
Since the jackpot occurrence probability is changed and controlled based on the number of hit balls, that is, the winning probability, it is possible to more accurately grasp the nail adjustment state of this table.

In this embodiment, an example is shown in which a detection switch is provided at the tip of the firing rail 13 as the number of shots hitting ball counting means 26. The hit balls may be counted. The number of shot balls can also be counted by counting the sum of the out ball and the winning ball.

Also, in the present invention, the number of winnings to the starting port can be measured in the same manner by measuring the number of times the symbol change is started on the symbol change indicator. In short, it goes without saying that the number of times the symbol variation indicator starts to change may be measured as a means for measuring the number of winnings to the starting opening.
