BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko gaming machine in which the odds of a big jackpot are changed to further enhance the game.

[0002]

2. Description of the Related Art As is well known, first-class pachinko game machines are
The game board is provided with a pattern variable display consisting of a color liquid crystal display, and when the starting winning hole is hit, the numbers 1-8 and symbols such as ☆ ◆ ◎ or characters (hereinafter,
For example, "design" is displayed in three columns so that it flows from top to bottom, the display variation stops after a few seconds, and the stop design has a predetermined probability (eg, 1/300), for example, "777". , When three rows like "☆☆☆" have the same pattern, it is a big hit, and the variable winning device (big winning opening) is configured to be opened by the operation of the electric opening / closing device. When a predetermined number (usually 10) of hit balls enter the variable winning device, or when a predetermined time limit (usually 30 seconds) elapses in the open state, the so-called first round ends and the variable winning device temporarily stops. However, if the ball hits the continuous winning opening (referred to as V zone) provided in the variable winning device during the first round, the second round starts immediately and the variable winning device again. Is opened and opened When a predetermined number of hit balls enter the variable winning device which is in the state again, or when a predetermined time limit has passed in the open state, the second round ends and the variable winning device closes again, but during the second round. When a ball hits the continuous winning opening provided in the variable winning device, the third round starts, the variable winning device is opened again, and thus the hitting ball is won in the continuous winning opening during each round. Under the condition, the variable winning device is continuously opened until the final round (for example, the 16th round).
In this way, during the period of the specific game state, the opening and closing door of the variable winning device is continuously opened up to the predetermined number of rounds, and it is extremely easy for the hit ball to enter. Usually, one winning ball is 15 prize balls. Is paid out, so that a large number of prize balls are paid out to the player once a big hit occurs.

By the way, since this kind of pachinko game machine pays out a large number of prize balls when a big hit occurs, the probability of occurrence is 1/300 or 1/25.
It had to be set to a low probability of 0. For this reason, it is not easy to generate a jackpot, forcing the player to endure a very large number of times until a jackpot occurs, which may impair the interest.

Therefore, a probability-changing type pachinko gaming machine which raises the jackpot occurrence probability when a predetermined condition is satisfied has been conventionally known.

[0005]

However, in the conventional pachinko game machine, it is not possible to increase the probability of jackpot occurrence unnecessarily even if it is a probability variation type, so it is often the case that the jackpot does not occur for a long time. There was a risk that the player would get bored.

Therefore, the present invention provides a pachinko gaming machine in which the probability of jackpot occurrence is diversified so that more pachinko fans can enjoy its delicacy.

[0007]

Therefore, the pachinko gaming machine of the present invention generates a jackpot with a predetermined probability by determining a random number acquired when a hit ball wins a starting winning opening, and a variable winning device. In a pachinko gaming machine that continuously opens the game, the number of prize balls paid out by one winning ball (hereinafter referred to as the unit prize ball) is changed, and the jackpot occurrence probability is changed according to the change of the unit prize ball number.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. The front of the game board 1 in this pachinko game machine is shown in FIG. 1, and in the figure, 2 is a pattern variation display consisting of a color liquid crystal display provided on the game board 1, 3 is a normal winning opening, 4 is passing Gate 5 is a start winning opening, and 6 is a segment digital display provided in front of the starting winning opening. Further, 7 is a variable winning device which is provided below the starting winning port 5 and has a large rectangular big winning port. The winning device 7 is provided with a door 8 which opens and closes forward by the operation of a solenoid. A continuous winning opening 9 is provided in the door 8. In addition, reference numeral 10 denotes four holding display lamps which are provided to store the number of hit balls when the prize winning opening 5 is won during the variable display of the pattern change display 2 and hold the start.

FIG. 2 is a block diagram showing an input / output device related to the present invention, which is connected to a control board 15 composed of a CPU, a ROM, a RAM and an I / O. Reference numeral 20 denotes a ball hit by the passage gate 4. A passing detection switch, 21 is a start switch for detecting a hit ball that has been won in the starting winning opening 5, 22 is a count switch for counting winning balls to the variable winning device 7, and 23 is a winning ball for the continuous winning opening 9. It is a continuation switch to detect. Further, the control board 15 is connected to the symbol variation display 2, the digital display 6, the hold display lamp 10, and a solenoid 24 for opening and closing the door 8 of the variable winning device 7. A payout control board 25 for controlling a prize ball payout device (not shown) is connected.

In the pachinko gaming machine shown in this embodiment, the number of prize balls to be paid out per winning ball to be won in the variable winning device 7 (hereinafter referred to as the unit prize ball number) is the lower part of the symbol variable display 2. The text is displayed as a ticker like an electronic bulletin board with characters such as "There are currently 12 jackpots." Then, the number of unit prize balls is determined by the procedure shown in the flowchart of FIG. That is, in step a, the digital display 6 variably displays, for example, 5 → 6 → 10 → 12 → 15 at intervals of 1 second, and in step b, it is detected that the hit ball has passed through the passage gate 4. And the variable display is stopped, and the stopped number is set as the unit prize ball number in step d, and a specific number is set according to the unit prize ball number, and the unit prize ball number is set in the symbol variable display 2 in step e. The telop is displayed on the lower part as described above, and the payout control board 25 is instructed of the number of unit prize balls in step f.

The specific number set in the step d determines the jackpot occurrence probability. As shown in Table 1, when the number of unit balls is 15, the jackpot occurrence probability is 4/1200. When the number of unit award balls is 12, the jackpot occurrence probability is 5/1200, and similarly, when the number of unit award balls is decreased, the jackpot occurrence probability is high and the number of unit award balls is 5. The jackpot occurrence probability is set to 12/1200. This increases the number of random numbers to be jackpot as the number of unit prize balls decreases,
By determining the number of unit prize balls and the jackpot occurrence probability according to the setting table of Table 1 so that the product of the number of unit prize balls and the jackpot occurrence probability is always constant (0.05 in this case), The above can change both without any advantage or disadvantage.

[Table 1]

In the jackpot determination routine shown in FIG. 4, when a ball hits the starting winning opening 5, a random number is obtained in step 2, and in step 3, the symbol variation display 2 is set to 1
Numbers up to 8 and symbols such as ☆ ◆ ◎ or symbols such as characters are variably displayed in 3 rows so as to flow from top to bottom, and the display variation is stopped after a few seconds, and acquired in step 2 in step 5. It is determined whether or not the generated random number is the specific number, and if it is not the specific number, a defective display is made in step 6, and if it is the specific number, the big hit is displayed in step 7, and the process proceeds to step 8. By operating the solenoid 24, a jackpot process for continuously opening the variable winning device 7 is performed. In this jackpot, the variable winning device 7 is repeatedly opened up to the 16th round under the condition that the continuous winning opening 9 is won, so that a large number of hit balls can win the variable winning device 7.

At this time, the prize winning balls that have won in the variable winning device 7 operate the prize ball payout device to pay out the above-mentioned unit prize balls per prize ball. For this reason, if a big jackpot occurs when the jackpot occurrence probability is low, the number of unit award balls is large, and there is a chance that a large number of award balls will be obtained during the jackpot period. Conversely, when the jackpot occurrence probability is high, it occurs. Since the number of unit prize balls is small in the jackpot, the number of prize balls that can be obtained during the jackpot period is small. Therefore, in this embodiment, there is no theoretical advantage or disadvantage in whatever the number of unit prize balls is set, and a fair service can always be provided.

In the variation count monitoring routine shown in the flowchart of FIG. 5, each time the symbol is variably displayed on the symbol variation display 2, the process moves from step A to step B and the variation number H is added to the variation number H. When the number of times is 1000 times or less, the specific number is set according to the setting table of Table 1 as described above, and when the number of fluctuations H reaches 1000 times, the process shifts from step C to step E and step F, and the symbol fluctuation display 2 displays “super bonus”. Is displayed and a specific number is set according to the setting table of Table 2. The setting table of Table 2 has twice the jackpot occurrence probability as compared to the setting table of Table 1. This makes jackpots more likely to occur and prevents jackpots for a long time (that is, even if the number of fluctuations is large. It often becomes possible to avoid situations where a big hit does not occur. After the jackpot is generated by this super bonus setting, the number of fluctuations H is initialized in step 9 shown in FIG.

[Table 2]

In the above embodiment, the ball is passed through the passage gate 4 so that the variable display of the digital display 6 is stopped and the stopped number becomes the number of unit prize balls. Alternatively, the number of unit prize balls may be drawn by a display such as roulette, and the number of unit prize balls may be determined according to the result. Also,
Not only the number of unit prize balls but also the jackpot occurrence probability at that time may be simultaneously displayed to the player, or only the jackpot occurrence probability may be displayed. Further, the display location is not limited to the plane of the game board such as the symbol variation display shown in the embodiment, but may be displayed anywhere such as a corner lens where the player can see.

Although not shown, when it is detected by the above-described variation count monitoring routine that the variation count H has reached a predetermined count, the jackpot occurrence probability is increased and the symbol variation display 2 or the like displays, for example, a roulette wheel. Is displayed and the number of unit prize balls is, for example, 5 to 1 by lottery.
By selecting from five, it is possible to provide the player with an appropriate amount of service that is a so-called jumping ball hit when the big hit does not occur for a long time. In addition, only when the big hit in the above situation cannot be generated even after the predetermined number of times, the number of unit prize balls is set to 15 or more (eg, 20) as a "Big Special Bonus", and the big hit is generated. You may increase the probability.

Further, in this embodiment, the number of unit prize balls by the prize balls won in the variable prize device 7 is changed, but the prize holes won in the other prize holes such as the normal prize hole 3, the start prize hole 5 and the like. The number of unit prize balls by sphere may also be changed.

It is also possible to irregularly fluctuate the number of unit prize balls, for example, by randomly varying the number of unit prize balls every 3 minutes. By allowing the player to see the change situation, a new taste that cannot be obtained by the conventional pachinko gaming machine can be obtained.

Further, the number of unit prize balls and the jackpot occurrence probability are varied so that the product of the number of unit prize balls and the jackpot occurrence probability is always constant, but this may not necessarily be constant. In addition, as described above, when some conditions are met, such as when the number of fluctuations increases and a big jackpot does not occur for a long time, the number of unit prize balls and the jackpot occurrence probability are increased to make it more than usual. This distinctive advantage allows this pachinko machine to be better characterized. In addition, in order to monitor the situation in which a big hit has not occurred for a long time, it is not limited to counting the number of symbol fluctuations, and the number of hits to the starting winning opening may be monitored.

[0020]

As described above, according to the present invention, a jackpot is generated with a predetermined probability by determining a random number obtained when a hit ball wins a starting winning opening, and the variable winning device is continuously opened. In a pachinko game machine, the number of prize balls paid out by one winning ball is changed, and the jackpot occurrence probability is changed in accordance with the change, so that a situation in which a jackpot does not occur for a long time continues and the player gets bored. There is a remarkable effect that makes pachinko games even more entertaining.
