Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine such as a pachinko machine, an arrange ball machine and a sparrow ball machine.

[0002]

2. Description of the Related Art Conventionally, in a ball game machine such as a pachinko machine, a normal symbol starting means for detecting a game ball on a game board, and a normal time varying when this normal symbol starting means detects a game ball A normal symbol display means for displaying the symbol, a judgment symbol starting means for releasing the normal symbol after stopping the normal symbol display means for a predetermined time when the symbol is a winning symbol, and a predetermined time when the determination symbol starting means detects a game ball. Equipped with a determination symbol display means for displaying a variable determination symbol, the stop symbol of the variable symbol display means and the stop symbol of the determination symbol display means become a predetermined combination, when a hit occurs, it is advantageous to the player. And a profit state generating means for generating various profit states.

Ordinary symbol display means, the determination symbol display means adopts a random number control system, extracts the random number at the time when the starting means detects the game ball, and after the fluctuation, the probability that the symbol hits the ordinary symbol and the determination symbol. I'm trying to control. Further, the probability control means for controlling the hit occurrence probability of the normal symbol display means according to the determination symbol after the change of the determination symbol display means is provided, and the high probability when the determination symbol of the determination symbol display means is a constant symbol among the hit symbols. The state is switched to the low-probability state at the time of other winning symbols, respectively.

[0004]

In this type of ball game machine, when the hit of the symbols of the variable symbol display means and the judgment symbol display means becomes a predetermined predetermined combination, the profit state generation means makes a large amount. The winning means repeats the opening / closing operation intermittently for a plurality of times, and when this big winning means is in the open state, a great amount of profit is returned to the player, such as a large number of game balls winning the big winning means. become.

Further, the probability control means operates depending on how the judgment symbol after the judgment symbol display means changes, and the hit occurrence probability of the normal symbol display means automatically switches during the game, so that the probability fluctuation causes the player's tension. It is possible to raise the feeling and play a game full of interest for the player. For this reason, this ball game machine is highly popular among players, and is now widely used in many game stores.

In this ball game machine, when the normal symbol of the normal symbol display means hits and stops at the symbol, the determination symbol starting means opens for a predetermined time, for example, about 6 seconds, during which time the determination symbol starting means is played. It is necessary to insert a ball and operate the determination symbol display means. For this reason, in order to obtain a jackpot early, it is an important point how to efficiently enter the game ball into the determination symbol starting means.

However, during the opening of the judgment symbol starting means, it is possible to put a maximum of about 3 to 4 game balls in this judgment symbol starting means, but normally, one time of the judgment symbol starting means. Judgment symbol display means is only activated once for opening, and no matter how efficiently the game balls can be put in the judgment symbol starting means, it is possible to activate the judgment symbol display means for the number of entered balls. Can not.

Therefore, depending on the determination symbol of the determination symbol display means, if the hit occurrence probability in the ordinary symbol display means is switched to the high probability state by the probability control means, the ordinary symbol display means is in the high probability state. If it becomes a big chance of a big hit occurrence, even if the hit occurrence probability of the normal symbol display means becomes large, unless the number of times the judgment symbol display means operates increases, the high probability of the normal symbol display means becomes a big hit. It does not lead to the occurrence of the above, but the player's frustration is only increased, and the player's motivation for the game is only lost.

The present invention has been made in view of such conventional problems,
The judgment symbol display means has a time shortening function to shorten the fluctuation time, and by shortening this fluctuation time, the jackpot occurrence probability is substantially increased, increasing the possibility that a great profit can be returned to the player. It is an object of the present invention to provide a ball-and-ball game machine that can arouse a player's motivation for a game and can enjoy the game in a tense state with a sense of expectation.

4 and 5 are block diagrams of the control device. In FIG. 4, 34 is a calculation control means 34 composed of a microcomputer or the like. In this calculation control means 34, a normal symbol display means 23, a judgment symbol display means 24, a normal symbol starting means 13, a stop switch 32, a sorting means 27 The operation area switch 33 and the like are connected, and the prize winning means 15 and the like are connected.

The arithmetic control means 34 is constructed as shown in FIG. That is, in FIG. 5, 35 is a normal symbol change processing means for changing the normal symbol of the normal symbol display means 23 for a predetermined time, and a random number at the time when the game ball wins the normal symbol starting means 13 is extracted, and the random number is used. The normal symbol of the normal symbol display means 23 is controlled to stop at the designated symbol. In addition, this normal symbol variation processing means 35,
When the extracted random number is a random number, the normal symbol display means 23
"7/7" is displayed on the normal pattern of, and when it is out of random number,
The symbols other than "7.7" are displayed.

Reference numeral 36 is a normal symbol hit judging means, which judges whether or not the stopped symbol after the change of the normal symbol display means 23 is a hit symbol, for example, "7.7", and when the hit symbol is open / close winning means 26. Is opened for a predetermined time, for example, about 6 seconds. 37 is a determination symbol variation processing means for varying the determination symbol of the determination symbol display means 24 for a predetermined time, to extract a random number at the time when the stop switch 32 detects a game ball, and to stop at the symbol designated by the random number. The determination symbol display means 24 is designed to control the determination symbol.

The determination symbols of the determination symbol display means 24 include, for example, two hit symbols "3" and "7". Then, the determination symbol variation processing means 37 displays the symbol on the determination symbol of the determination symbol display means 24 when the extracted random number is two hit random numbers corresponding to "3" and "7". .

38 is a jackpot determination means, when the stop symbol of the normal symbol display means 23 and the stop symbol of the determination symbol display means 24 become a predetermined combination, that is, the normal symbol display means 23 When the symbol becomes "7.7", and the determination symbol of the determination symbol display means 24 becomes "3" or "7", it is set as a big hit, and the determination symbol display means in the determination symbol variation processing means 37. Each time the 24 variation processes are completed, it is determined whether or not the combination is the jackpot.

39 is a distribution control means for controlling the distribution body 31 of the distribution means 27, which issues an operation command every time the variation process of the determination symbol variation processing means 37 ends, and when there is a jackpot signal from the jackpot determination means 38. The distribution body 31 is configured to drive the distribution body 31 to distribute the game ball to the right side and to distribute the game ball to the left side at other times.

Reference numeral 40 is a profit state generating means, which generates a profit state advantageous to the player when the operating area switch 33 detects passage of the game ball after the stationary game balls are distributed to the right by the distribution body 31. It is designed to let you. That is, this profit state generation means 40, every time a game ball wins the third type starting means 19, the opening and closing plate of the big winning means 20 is intermittently opened and closed a predetermined number of times, and most of the game balls falling from above are dropped. The big winning means 20 is made to win, and a great profit is returned to the player.

41 is a probability control means for controlling the hit occurrence probability of the normal symbol display means 23, according to the judgment symbol after the fluctuation of the judgment symbol display means 24, the probability of hit occurrence of the normal symbol display means 23 from the next changing operation It is designed to be switched. That is, the probability control means 41 is a jackpot determination means 38
By the output from, when the judgment symbol of the judgment symbol display means 24 becomes "7" in the winning symbol, the low probability state from the next changing operation to the high probability state, when it becomes "3",
The high-probability state is switched to the low-probability state from the next fluctuating operation.

Incidentally, the hit probability of the normal symbol display means 23 is, for example, about 1/40 when the probability is low, and about 8/40 when the probability is high. And usually 1 /
It is in the state of 40 and has a high probability of 8/40 when the probability changes. The probability of hitting the determination symbol display means 24 is 2 /
It is about 19.

Reference numeral 42 is a fluctuation time shortening means for shortening the fluctuation time of the judgment symbol of the judgment symbol display means 24, under a specific shortening condition, that is, when the probability is changed to a high probability state at "7".
The variation time from the next time of the determination symbol of the determination symbol display means 24 is shortened from the normal time T to the time t.
In addition, the normal time T of the judgment symbol display means 24 is about 6 seconds, the time t after shortening is about 2 to 3 times during one opening time of the opening and closing winning means 26, the judgment symbol display means 24 Is set to about 0.5 seconds, which is 1/10 or less of the opening time of the opening / closing winning means 26 (about 6 seconds).

Reference numeral 43 is a shortening canceling means for canceling the shortening of the fluctuation time by the fluctuation time shortening means 42.
That is, the reduction of the fluctuation time is canceled from the next time when "3" is returned to the low probability state.

Next, the operation of the above pachinko machine will be described with reference to FIG.
It will be described with reference to the flowchart of FIG. In the game, when the operation handle 10 of the firing means 9 is operated, the game balls are supplied one by one to the firing position of the firing rail in conjunction with the firing operation of the firing means 9, and the game balls are sequentially moved along the guide rail 11. It is fired at the upper side of the game board 5.

The game balls shot on the upper side of the game board 5 fall downward along the board surface of the game board 5. At this time, as shown in FIG. 6, the game ball is a normal symbol starting means.
When entering 13 (step S1), the normal symbol variation processing means 35
Extracts the random number at that time, and performs the variation process of the normal symbol of the normal symbol display means 23 according to the random number (step S
2), the normal symbol of the normal symbol display means 23 is changed for about 6 seconds so as to stop at the stop symbol corresponding to the random number at the time of extraction (step S3).

In the variation process by the normal symbol variation processing means 35, if the extracted random number is a random number, the symbols on the left and right symbol display portions 25 of the normal symbol display means 23 are "7.7".
Stop to display the hit pattern. At this time, the probability of hitting the normal symbol display means 23 to hit the symbol is
It is controlled by the probability control means 41. That is, usually the probability control means 41 is set so that the normal symbol variation processing means 35 is in a low probability state, this normal symbol variation processing means 35 of the normal symbol display means 23 by random number processing in the low probability state. Change the design.

The normal symbol of the normal symbol display means 23 is hit by the variation process in the normal symbol variation processing means 35, and the symbol "7"
If "7" is displayed, the normal symbol hit determination means 36 determines the hit of the ordinary symbol and outputs an opening command (step S4), so that the pair of open / close claws 28 of the open / close winning / winning means 26 rotate left and right. For about 6 seconds (step S5).

When the first game ball wins the opening / closing prize means 26, the game ball falls straight and the distribution means 27
It enters into the sorting case 29 and stops at the stop position 30, and the stop switch 32 detects the stop of this game ball (step S
6). When the stop switch 32 detects a game ball,
Judgment symbol fluctuation processing means 37 extracts the random number at that time, performs the fluctuation process of the judgment symbol of the judgment symbol display means 24 according to the random number (step S7), and stops at the stop symbol according to the random number at the time of extraction. The determination symbol of the determination symbol display means 24 is changed for about 6 seconds (step S8).

During the change of the judgment symbol display means 24, the opening and closing winning means 26 can win a maximum of about 3 to 4 game balls, but if the first game ball stops at the stop position 30. After that, the game balls to win the prize pass through the sorting case 29, are guided to the rear side of the game board 5, and are processed as the prize balls.
During the variation process by the determination symbol display means 24, if the extracted random number is a hit random number, the determination symbol of the determination symbol display means 24 stops at the hit symbol of “3” or “7”, and if it is a random number, Stop with a deviation pattern other than "3" or "7".

When the determination symbol of the determination symbol display means 24 is "3" or "7" of the winning symbol, the jackpot determining means 38 determines that it is a jackpot (step S9), and it is sorted by the jackpot signal from this jackpot determining means 38. The control means 39 works, and the game balls are distributed to the operation area side on the right side by the distribution body 31 (step S10). And stop position 30
Since the game ball is guided to the rear side of the game board 5 via the operation area side, the operation area switch 33 in the operation area detects the game ball and the profit state generating means 40 operates (step S1).
1).

Therefore, if a game ball is won in the third-type starting means 19 thereafter (step S12), the opening / closing plate of the big winning means 20 is intermittently opened and closed a predetermined number of times for each winning, and falls from above. Most of the game balls are awarded to the big winning means 20,
A great profit is returned to the player (step S13).

On the other hand, if the judgment symbol after the changing operation of the judgment symbol display means 24 is "3" or "7", the probability control means 41 works as shown in FIG. 7 to change the hit occurrence probability of the normal symbol. And, as shown in FIG.
42 or the shortening canceling means 43 works to shorten the fluctuation time of the judgment symbol or cancel the shortening.

That is, as shown in FIG. 7, when the jackpot determination means 38 determines that the jackpot is a jackpot, it is further determined whether the determination symbol is "3" or "7" (step S1).
4). Then, if the determination symbol is "7", the probability control means 41 operates to perform a switching process to switch the normal symbol variation processing means 35 from the low probability state to the high probability state from the next occurrence probability of hit (step S15). ). If the determination symbol is "3", the probability control means 41 operates in the high probability state to perform processing for returning to the normal low probability state (step S16).

If the judgment symbol is "7", as shown in FIG. 8, the fluctuation time shortening means 42 operates, and the fluctuation time of the judgment symbol from the next time of the judgment symbol display means 24 is changed from the time T to the time. A shortening process for shortening to t is performed (step S17).
If the judgment pattern is "3", the shortening releasing means 43 operates,
When the variation time of the determination symbol is in the shortened state, the process of canceling the shortening and returning to the normal time t is performed (step S18).

Therefore, after the normal symbol hit occurrence probability is set to a high probability state, the opening and closing winning means 26 is once closed,
Once again, if the game ball wins the normal symbol starting means 13, the normal symbol of the normal symbol display means 23 tends to be a winning symbol of "7.7". Then, when the normal symbol of the normal symbol display means 23 becomes a winning symbol of "7.7", the opening / closing winning means 26 opens for about 6 seconds to win the game ball, and the game ball is placed at the stop position 30 of the allocating means 27. Is stopped, the stop switch 32 detects the game ball, and the judgment symbol change processing means 37 changes the judgment symbol of the judgment symbol display means 24.

However, at this time, since the variation time of the determination symbol is shortened to the time t by hitting the determination symbol of the previous time, the determination symbol display means 24 immediately stops after only fluctuating for about 0.5 seconds. Then, when the fluctuation operation of the determination symbol display means 24 is stopped, the jackpot determination means 38 determines whether or not it is a jackpot, and according to the determination result, the distribution body 31 of the distribution means 27 places the stopped game ball on either side. I will sort it out.

That is, in a state in which the fluctuation time of the fluctuation time shortening means 42 is shortened, the judgment symbol of the judgment symbol display means 24 fluctuates for a very short time of time t, for example, about 0.5 seconds, and immediately after the fluctuation starts. It is determined whether or not it is a winning symbol by stopping, and whether the winning symbol is "3" or "7".

Therefore, the game ball enters the opening and closing winning means 26, only the determination symbol of the determination symbol display means 24 changes momentarily when the stop switch 32 detects the game ball, and the determination symbol is displayed immediately. The determination pattern of means 24 has stopped,
The jackpot determining means 38 can determine whether or not it is a jackpot.

Therefore, in any of the case where the determination symbol is a winning symbol or a deviating symbol, the distribution control means 39 works by the determination result of the big hit determination means 38 or the variation end command of the determination symbol variation processing means 37. The game balls stopped at the stop position 30 can be distributed to the left or right by the distribution body 31. Then, immediately after that, even if there is a game ball that enters the distribution means 27 through the opening / closing prize means 26, the game ball can be stopped at the stop position 30 by the distribution body 31, and the stop switch 32 is in the stopped game. The sphere can be detected reliably.

The time t after shortening is about 0.5 seconds,
Since it is 1/10 or less of the opening time (about 6 seconds) of the opening and closing winning means 26, during the opening time of the opening and closing winning means 26, the opening and closing winning means 26 wins 3 to 4 game balls, and the judgment is made. It is possible to change the determination symbol of the symbol display means 24 3 to 4 times.

By shortening the determination symbol of the determination symbol display means 24 to the time t (about 0.5 seconds) in this way, while the opening and closing winning means 26 is open, by the game ball winning the opening and closing winning means 26. The determination symbol of the determination symbol display means 24 can be efficiently changed. Therefore, the determination symbol display means
Every time the determination symbol of 24 is determined in an extremely short time, the combination of the determination symbol of this determination symbol display means 24 and the ordinary symbol of the ordinary symbol display means 23 is compared, and the jackpot determination means 38 is a big hit in a short time. Since it can be repeatedly determined whether or not it is possible, the player can continuously play the game with a feeling of tension.

Especially when the fluctuation time is shortened by the fluctuation time shortening means 42, the probability control means 41 normally causes the symbol display means 23
Since the hit occurrence probability is in a high probability state, in combination with the change of the hit occurrence probability, the normal symbol display means 23
Ordinary symbol is "7.7", the determination symbol of the determination symbol display means 24 is "3" or "7", and there is a great possibility that a big jackpot will occur. You can play games with a sense of expectation in returning profits. In addition, the determination symbol is "7" again during the shortening of the fluctuation time.
When it becomes, the shortening process is performed again after the jackpot process and the time t is continued.

If the judgment symbol of the judgment symbol display means 24 becomes "3" in the hit symbol, the probability control means 41 operates and the hit occurrence probability in the normal symbol display means 23 is a normal low probability state from the next time. Along with returning to, the shortening canceling means 43 works to cancel the shortening of the fluctuation time, and the judgment symbol display means 24 from the next time
The judgment pattern of is returned to the time T.

Therefore, the probability control means 41 changes the hit probability of the normal symbol depending on how the determination symbol of the determination symbol display means 24 changes during the game, and the variation time shortening means 42
Since the change time of the determination symbol can be shortened or shortened by the shortening canceling means 43, the entire game has a variety of interesting and entertaining game configurations, and the player can enjoy the game with fun.

When the determination symbol of the determination symbol display means 24 becomes "3" of the jackpot symbol, the shortening canceling means 43 cancels the shortening by the variation time shortening means 42, and the variation time of the determination symbol display means 24 Although it is returned to the normal time T, at this time at least the second big jackpot has occurred, so the reduction of the fluctuation time can be canceled after the tentative profit is returned to the player.

Although the embodiments of the present invention have been exemplified above, the present invention is not limited to the embodiments. For example, in the embodiment, the determination symbol display means 24 is provided between the two symbol display portions 25 of the ordinary symbol display means 23, but the ordinary symbol display means 23 and the determination symbol display means 24 are arranged vertically. Is also good.

Further, the variable time, the shortened time, the probability, etc. of the normal symbol display means 23 and the judgment symbol display means 24 are all examples, and the time and the probability are not limited. As the judgment symbol starting means 14, in the embodiment, it is configured by the opening and closing winning means 26 and the distributing means 27, but the distributing means
It is also possible to use the one in which the opening / closing claw 28 is provided at the entrance of the sorting case 29 of 27. Other conditions may be set for the specific shortening condition and the specific releasing condition.
