Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hit probability control device for a ball game machine such as a pachinko machine equipped with a symbol changing device.

[0002]

2. Description of the Related Art Conventionally, a ball game machine, for example, a pachinko machine, is provided with a symbol display device having a plurality of symbol display portions at the center of a game board, and a game ball enters a predetermined starting gate. Sometimes, the symbols on each symbol display unit of the symbol display device are changed for a predetermined time, and when the stopped symbol after the change becomes a predetermined hit symbol, the specific winning device is operated in an open state. .

The probability of occurrence of a stop symbol after a change being a winning symbol is preset by a random number or the like in a control device such as a microcomputer, and is automatically set to a high probability and a low probability as follows. It is designed to be switched automatically. That is, when the power is turned on at the start of the game, there is a low probability state. Then, after the start of the game, the game ball enters a predetermined start gate, the symbols of each symbol display unit of the symbol display device fluctuate, and then the specific winning device is activated when each stop symbol becomes a predetermined hit symbol. Then, the specific winning device is opened.

On the other hand, at the same time, the probability of hit occurrence is switched from a low probability to a high probability. Then, if any of the game balls that have entered the special winning device passes through the special operation area, the special winning device such as a wide big winning opening operates for a certain period of time, and while the special winning device is operating, The probability of occurrence is forcibly returned from high to low. In addition, if a game ball enters this special prize device, unlike the case where it enters into other places, about 2 times as many game balls will be paid out as a prize ball, and special profit will be returned to the player. To do.

When the operation of the special winning device is stopped, the winning probability is returned to the high probability before the operation, and the game is continued in the high probability state. Then, each time the special winning device is operated, the probability of hitting is returned to a low probability only during the operation, and if the special winning device is operated a plurality of times, for example, about three times,
Simultaneously with the start of the third operation, the probability of hit occurrence is completely returned to a low probability to maintain a low probability state, and even if the special winning device stops operating, it is switched to the high probability state again unless it becomes a hit state. It will not be replaced.

[0006]

In the conventional pachinko machine, when the symbol of each symbol display section of the symbol display device changes at a low probability, when the stopped symbol hits and displays the symbol,
The probability of hitting is switched from a low probability to a high probability, and when the special winning device is operated a plurality of times in a high probability state, the high probability is canceled to return to a low probability.

Therefore, after the special winning device has operated a plurality of times, the game must be played in the low-probability state unless a hit state occurs in which the stop symbol of the symbol display device is the symbol. Therefore, there is a drawback that the game has to be a game that is extremely uninteresting for the player.

The present invention has been made in view of such conventional problems.
After the symbols on each symbol display unit of the symbol display device have changed, when the winning symbol is displayed, the probability of hitting can be switched to a high probability or a low probability depending on the combination of the winning symbols, and it is always rich in variation and entertaining. It is an object of the present invention to provide a hit probability control device for a ball game machine capable of playing different games.

FIG. 1 is a block diagram of a control system that controls the control operation of a pachinko machine. In FIG. 1, reference numeral 34 denotes a random number generating means, which is adapted to generate a low-probability-per-judgment random number value and a high-probability-per-judgment random number value at the same time when power is turned on.

35 is a random number determination means, the game ball is the starting gate
When passing 14, the random number value generated at that time by the random number generation means 34 is extracted, and the random number value is compared with a preset winning symbol value to determine whether or not it is hit. The display data is stored in the stop symbol display buffer if it is out.

Reference numeral 36 is a symbol variation processing means, which is a symbol display device 13

The function to maintain and the specific input when the probability of hit occurrence is high.
When the prize device 17 operates, the symbol display device only during the operation
13 Hit probability is forcibly cut from high probability to low probability
It has the function to change. In addition, the random number generation means 34, the random number determination means 35, the symbol variation processing means 36, the hit determination means 3
7, the winning symbol determination means 38, the probability switching means 39 and the like are configured by a microcomputer 40.

Reference numeral 41 is a ball payout device, and the game balls are prize holes 7, 8,
9,12, start opening 10,11, 1 when entering specific winning device 15
Seven game balls are paid out for each one, and when the game balls enter the special winning device 17, 15 game balls are paid out. 42 is an input / output circuit.

Next, the operation of the above configuration will be described with reference to the flowchart of FIG. When the power of the pachinko machine is turned on (step S1), the probability switching means 39 sets the high probability / low probability state determination flag F to low probability 0 (step S2), and starts in the low probability state. Then, the high-probability-per-judgment random number value and the low-probability-per-judgment random number value generated by the random number generator 34 are updated (steps S3 and S4). In this case, if the winning probability is 1/20 when the probability is high and 1/200 when the probability is low, the random number generation means 34 uses, for example, a high-probability-per-judgment random number value of 0 to 19 and a random probability of 0 to 1999. The random number for determination with a low probability is generated.

Then, the game ball launched on the game board 5 by the operation of the operation handle 30 passes through the starting gate 14.
When this starting gate 14 detects a game ball (step S
5) After the random number determination means 35 extracts the random number value at that time and first determines whether the determination flag is 1 at high probability or 0 at low probability (step S6), Whether or not it is a hit is determined from a random number value and preset hit determination data, and if it is a hit, the hit display data is
If it is off, the off display data is stored in the stop symbol display buffer (step S7 or S8). in this case,
Since the low-probability state remains after the power is turned on, step S
Process 8 is performed.

Next, the symbol variation processing means 36 judges whether or not the symbol variation processing is being performed (step S9), and the symbols displayed on the respective symbol display portions 19, 20, 21 of the symbol display device 13 cannot be visually identified. A symbol variation process for varying the velocity is performed (step S10). Then, the symbols on the symbol display portions 19, 20, 21 fluctuate for a predetermined time, and then stop in the order of left, right, and middle. The stop symbol at this time is determined by the display data stored in the stop symbol display buffer.

When the symbol variation process of the symbol display device 13 is completed (step S11), the hit determining means 37 determines whether or not the stopped symbol is a hit symbol, that is, whether the hit symbol is out or not (step S12). This hit determination is performed by comparing the random number value with the hit determination data on the basis of the hit determination random number value extracted when the game ball passes through the starting gate 14.

Incidentally, each symbol display section 1 of the symbol display device 13
If all the symbols displayed in 9,20,21 are the same, the hit symbols are 10 kinds from 0,0,0 to 9,9,9. Then, since 10 types of hit determination data corresponding to each of the winning symbols are set in advance, the extracted low probability hit random number value is compared with the 10 types of hit determination data, and if they match, a specific winning An operation process for operating the device 15 for a predetermined time is performed (step S13). On the other hand, if it is off, other game-related processing is performed (step S14).

Subsequently, the winning symbol determination means 38 determines whether the stopped symbol after the change is an odd symbol or an even symbol, even among the winning symbols (step S15). And, the symbols of the symbol display portions 19, 20, 21 are all odd numbers 1, 1,
If it is 1 etc., the flag F for judgment is determined by the probability switching means 39.
Is changed from 0 to 1 and the probability of hitting is switched from low probability to high probability (step S16). On the contrary, all even numbers 2, 2,
If it is 2, etc., the determination flag is left at 0 and the low probability state is continued (step S17).

For example, if the symbols on the symbol display portions 19, 20, and 21 are 1, 1, 1 respectively, the winning probability is switched to a high probability through steps S15 and S16. Then, after that, the following operations are repeated from step S3. During the game in this high probability state, the game ball passes through the starting gate 14 again, and if the display symbols of the symbol display units 19, 20, 21 of the symbol display device 13 are changed, all of the symbols are If the numbers are even numbers 2, 2, 2, etc., the winning probability is switched to a low probability through steps S15 to S17.

During a game in a high probability state or a low probability state
In, the stop symbol hits the third symbol in the symbol, that is,
When 0,0,0 is output, the probability of winning is not changed.
Instead, it remains the probability of hit occurrence at that time. In addition, all the game balls that entered the specific winning device 15 are in the center case 16
At this time, the game ball is a special operation area in the center
If it passes 22, the special winning device 17 is activated and the special winning opening 23 is opened. At the same time, the winning probability is forcibly switched from the high probability to the low probability while the special winning device 17 is in the operating state. Therefore, this special winning device 17
During the operation of the
The probability that a game ball will pass through the special operation area 22
As the number of game balls decreases during the operation of the special winning device 17,
When passing through the special operation area 22, the special winning device 17
Even machines that stop motion are forced to switch to a low probability.
By changing the profit status of the player
Can be maintained.

Therefore, each symbol display section 1 of the symbol display device 13
If the stop symbol of 9,20,21 is an odd symbol of the winning symbols as A, and the symbol of even symbols as B, the probability of winning is a high probability and a low probability in the relationship shown in FIG. And are sequentially switched to. In this way, each time the hit state occurs, you have the opportunity to change the hit occurrence probability, and since the hit occurrence probability switches depending on whether the design at that time is an odd design or an even design among the winning designs, It is possible to play games that are rich in variety and entertaining compared to.

In particular, the winning symbol has a high probability switching symbol and
And low probability switching design, and the third design other than these
Divide, do not change the probability of winning when this 3rd pattern
Because I am trying to avoid the occurrence frequency of winning symbols
If you can easily set the ratio of high probability state and low probability state
Both, high probability switching design and low probability switching design and third
High probability by combining with the design of
And the low probability can be changed arbitrarily. In addition,
The pattern for switching the probability of hit occurrence is not limited to odd numbers and even numbers, and other combinations may be used.
Further, the symbols displayed on the symbol display portions 19, 20, 21 of the symbol display device 13 may be other than the numbers.

In the embodiment, the specific winning device 15 and the special winning device 17 are provided separately, but the specific winning device 15 may have both functions, and the specific winning device 15 is advantageous for the player. It is sufficient if it has a function to work.
In addition, it goes without saying that the present invention can be similarly implemented in a ball game machine other than a pachinko machine.
