DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art In a ball game machine, for example, a pachinko machine, a game board is provided with a variable symbol display means having a plurality of symbol display portions and a start means for detecting entering or passing of a game ball. When the means detects a game ball, the symbol of each symbol display portion of the variable symbol display means is changed for a predetermined time, and when the stopped symbol after the change becomes a specific jackpot symbol, the special winning means is opened and closed a predetermined number of times. After the game ball that has won the other winning means passes through the special operation area inside, the large winning means is opened and closed a predetermined number of times each time the game ball wins the specific starting means. There are some that generate large jackpot rights and return profits.

In the CR machine, when the stop symbol of the variable symbol display means stops at the big hit symbol and a big hit occurs,
Depending on the type of the jackpot symbol, there is a probability variation type in which the occurrence probability of the jackpot from the next time is switched to a high probability of about 10 times.

[0004] In these pachinko machines, if a big hit occurs on the variable symbol display means side, a large number of game balls win the large win means while the large winning means repeats the opening and closing operations thereafter, and the player receives a great deal of money. In the case of a probability variation formula, once a big hit occurs, the state is switched to the high probability state from the next time, so that the big hit easily occurs. For this reason, there is an advantage that the player can play a game while expecting a large return profit, and the popularity of the player is high.
At present, it is widely used in many game stores.

[0005]

In a game store where pachinko machines and the like are installed, various services have conventionally been provided to the player in order to operate the game attractively to the player and obtain as many customers as possible. Activities. In particular, when looking at all business hours during the day, a large number of players enter from the afternoon to the evening, but in the morning of a certain time from the start of business, the number of visitors to each game store is extremely large. At the same time, the company conducts various service activities to attract players during this time.

[0006] However, the conventional service activities are not based on the game content itself on the pachinko machine side, but are limited to a certain time from the start of business on that day, such as a morning service, or during a specific time period during business hours. Limited to the time service, with a focus on services other than the game content, such as drawing lottery such as lucky numbers based on the machine number attached to the pachinko machine and presenting the prize to the winner. It has become.

[0007] Therefore, the services of the conventional amusement store sufficiently satisfy the psychological desire of a player who enjoys a game with a pachinko machine or a player who desires to return a large profit. Instead, a new service that takes into account the game characteristics of pachinko machines is desired.

[0008] Also, since many current pachinko machines employ a random number control system so that a jackpot is generated with a predetermined probability, each game shop adjusts the interval between nails at the entrance side of the starting means. With so-called nail adjustment, etc., a service is provided for a specific number of pachinko machines so that game balls can easily enter the starting means, thereby increasing the payout rate and returning profits to the player. .

However, the service by the nail adjustment is fixed to the pachinko machine, and it is not possible to variably provide a service limited to a certain time in a morning service or a time service.
In view of such conventional problems, the present invention provides a ball game machine that can variably provide a game-related service to a player at a game store and can sufficiently answer the psychological desire of the player. The purpose is to provide.

[0010]

Is stored. The control board 36 is provided with a control system CPU, ROM, RAM, and the like, which will be described later, and also has a key switch 37 mounted thereon. The key switch 37 is for setting a probability, and is configured to insert a key through a key hole 38 formed in the control box 20 and perform a rotating operation.

As shown in FIG. 3, a guide rail 22 is annularly mounted on the game board 5, and the guide rail 22 is
Floating symbol display means 23, starting means 24, winning winning opening inside 22
25, a left winning opening 26, a right winning opening 27, a specific winning means 28, a lower winning opening 29, a third type starting means 30, a large winning means 31, and an out opening 32 are provided respectively.

The variable symbol display means 23 has three symbol display portions 34 in the left and right direction. When the starting means 24 detects the passing of the game ball, the symbol of each symbol display portion 34 is displayed for a predetermined time by random number processing. It is configured to fluctuate. In addition, each symbol display part 34 displays each symbol of 0-9 and A-F, for example.

The special prize winning means 28 is configured to be activated when the stop symbol of each symbol display section 34 of the variable symbol display means 23 becomes a specific jackpot symbol such as "7.7.7". . The inside of the specific winning means 28 is divided into three parts, and the center thereof is a special operation area 35.

FIG. 4 shows a control system. Numeral 39 denotes a random number generating means, which is configured to repeatedly generate a random number from 0 to 249 when the probability of occurrence of a jackpot is 1/250, for example. The random number generating means 39 is constituted by counting means 39a for counting clock pulses generated at fixed time intervals, and outputs a count value when the starting means 24 detects a game ball as a lottery random number. I have. The random numbers generated by the random number generating means 39 are set to a jackpot random number, a reach random number other than the jackpot random number, and a non-hit random number.

Numeral 40 is a random number lottery means. When the starting means 24 detects a game ball, the random number value of the random number generator 39 at the time of the detection is randomly selected. 41 is a random number determination means, which determines whether the lottery random number of the random number lottery means 40 is a jackpot random number, a reach random number, a missed random number, and when the random number is a jackpot random number, displays each symbol of the variable symbol display means 23 After the section 34 stops at the big hit symbol, the special prize winning means 28 is activated, and the special operation area 35 is enabled.

Reference numeral 42 denotes a fluctuation processing means. When the starting means 24 detects a game ball, each symbol display part 34 of the fluctuation symbol display means 23 is displayed.
Is changed for a predetermined time, and when the lottery random number of the random number lottery means 40 is a jackpot random number, for example, a big hit is made so that the stop symbol of each symbol display unit 34 becomes a big hit symbol such as "7.7 / 7". The stop symbol of each symbol display section 34 is configured to be controlled according to each random number such as a random number, a reach random number, and a random number out of order.

Reference numeral 43 denotes a right generating means. The random number judging means 41 judges that it is a jackpot random number and the specific prize means 28 becomes effective. When the game ball passes through the special operation area 35, the third kind starting means 30 Each time a ball enters, the special winning means 31 is opened and closed a predetermined number of times to generate a profit state advantageous to the player. The big prize winning means 31 has a maximum of 1 each time a game ball enters the third kind starting means 30 when a jackpot right is generated.
It opens and closes up to six times, and closes when 10 game balls win at each opening.

Numeral 44 denotes a probability setting means, and the variable symbol display means 23
The jackpot occurrence probability at which a jackpot symbol appears in a plurality of stages is selectively set in a plurality of stages. That is, the probability setting means 44 sets the occurrence probability within the range from the standard probability 1/250 to the highest probability 1/50, 1/200, 1/150, 1/1.
It is possible to select one of the probabilities by operating the key switch 37 before the operation of the pachinko machine 1 before turning on the power or within a certain period immediately after the power is turned on. It has become.

The probability setting means 44 is for setting the probability by changing the number of the total generated random numbers including the jackpot random numbers generated by the random number generating means 39. That is, since the random number generating means 39 is constituted by the counting means 39a, the probability setting means
The reference numeral 44 appropriately changes the preset value of the counting means 39a in increments of 50 within the range of 250 to 50, and sets the probability of occurrence of a jackpot to each probability.

Numeral 45 is a releasing means, after the end of the jackpot right.
When the power of pachinko machine 1 is turned off, 1/50, 1/1
This is for returning from a high probability of 00, 1/150 or 1/200 to 1/250 of a low probability (standard probability).

Next, the operation will be described with reference to the flowchart of FIG. The pachinko machine 1 is provided with a probability setting means 44 on the control board 36 on the back side of the game board 5, and before the pachinko machine 1 is operated, the gaming shop operates the key switch 37 to generate a jackpot. The probability can be set in five stages.

Therefore, when providing a service to a player as a morning service, after opening the front frame 4 of the pachinko machine 1 to the front side and opening the back side of the game board 5, the key hole 38 of the back cover 18 is inserted into the key hole 38 of the back cover 18. Insert the key switch 37
Is rotated to set a predetermined probability by the probability setting means 44 (step S1).

For example, the probability of the probability setting means 44 is usually 1/250 of the low probability (standard probability).
When 37 is operated, 1/200, 1/150, 1/100
And any one of 1/50 can be arbitrarily selected, so that the probability can be appropriately selected and determined according to the business policy of the game store.

In this way, all pachinko machines 1 in the game store
Or, for some pachinko machines 1, the probability setting means 44
After a predetermined probability is set (step S1), the power of each pachinko machine 1 in the store is turned on (step S2).
Then, in each pachinko machine 1, the control system is initialized, the probability set by the probability setting means 44 is read, and the set value of the counting means 39a constituting the random number generating means 39 is determined according to the set probability. (Step S3).

For example, from the low probability 1/250 to the probability 1/250
When set to 100, the set value of the counting means 39a is 2
Switching from 50 to 100, the counting means 39a repeats the counting operation of counting the clock pulse to 100, and sequentially generates random numbers 0 to 99 including the jackpot random number (step S4).

During the game, the firing handle 11 of the firing means 10 is operated with the game ball placed in the upper plate 7. Then, the game balls of the upper plate 7 are supplied one by one to the firing position of the firing rail in conjunction with the firing operation of the firing means 10, and the game balls are hit with a hitting hammer to sequentially play the game boards 5 along the guide rails 22.
Fire at the top side of the.

The game ball fired on the upper side of the game board 5 is
While falling along the surface of the game board 5, the player wins the winning prize port 25 or the like, or falls to the lower part of the game board 5 and out port 32.
And pass behind the game board 5. When the game ball passes through the starting means 24 below the fluctuating symbol display means 23 and this starting means 24 detects a game ball (step S5), the random number generating means 39 repeatedly generates a random number from 0 to 99 at all times. Since the random number lottery means 40 selects the random number at that time (step S6), the random number determination means 41 determines whether the random number is a jackpot random number, a reach random number, or a missed random number (step S6). In step S7, the symbols of the symbol display sections 34 of the symbol symbol display means 23 are varied by the variation processing means 42 (step S8).

At this time, the fluctuation processing means 42 is connected to each symbol display unit.
After the symbol 34 fluctuates for a predetermined time, the fluctuating symbol display means 23 is controlled so as to stop at a stop symbol corresponding to each of the jackpot random number, the reach random number, and the missed random number. For example, if the lottery random number is a big hit random number, the stop symbol of each symbol display unit 34 becomes a big hit symbol such as “7 / 7,7”. Is a non-stop symbol other than the jackpot symbol.

If the result of the random number judgment by the random number judgment means 41 is not a jackpot random number (step S9), the process returns to step S5. When the determination result is a jackpot random number (step S
9), activate the specific winning means 28 (step S10),
The game ball that has won the specific winning means 28 is in the special operation area 35.
(Step S11), the jackpot right generating means 43 operates to generate a right (jackpot state) advantageous to the player (step S12).

That is, if the game ball passes through the special operation area 35 of the special winning means 28, thereafter, every time the game ball enters the third kind starting means 30 (step S13), the special winning means 31 is opened for a predetermined time. Then, the special winning means 31 repeats the opening and closing operation up to 16 times (step S15).
For this reason, 10 game balls win during one opening of the special winning means 31, so 160 game balls win while opening and closing 16 times, and the ball payout means for each one of the game balls. A total of 2400 game balls, each of which is 16 pieces, are paid out as prizes, and a great profit is returned to the player.

When the big prize winning means 31 repeats the opening and closing operations 16 times and the jackpot right by the right generating means 43 disappears (step S15), the canceling means 45 operates to set the probability setting means.
The probability set by 44 is forcibly returned from 1/100 to a low probability of 1/250, and the morning service in which the jackpot occurrence probability is set to the high probability of 1/100 ends (step S16). Therefore, after that, the counting means 39a
Returns to 250, the counting means 39a repeats the counting operation up to 250, and the probability of occurrence of the jackpot becomes the standard probability 1/250. At the end of the game, the processing ends after step S17.

When the pachinko machine 1 is closed for one day and the power of all the pachinko machines 1 is turned off, even if there is no pachinko machine 1 in a state of high probability without any jackpot, the probability setting is performed. Means 44 forcibly returns from high probability to low probability 1/250. As described above, in the game store, if the probability setting means 44 sets a high probability before the operation of the pachinko machine 1, the probability that a big hit symbol appears and a big hit occurs in the variable symbol display means 23 becomes large. Through the opening and closing of the special winning means 31, a great profit can be returned to the player.

Therefore, unlike the service activity of the conventional game store, the service can be provided to the player through the game, thereby increasing the interest of the player and sufficiently responding to the psychological desire of the player.

The probability setting by the probability setting means 44 is performed before or after the power is turned on for a certain period of time, for example, in the pachinko machine 1.
It is done before the operation of. For this reason, the morning service provided in the morning when the number of players is small can be easily and effectively used as a part of the morning service, and the distrust of the player is caused as compared with the case where the probability is set in front of the player after the start of operation. No problem.

Further, since the probability setting means 44 can select and set five levels of probabilities, a large number of pachinko machines 1 can be installed in the game store.
In the case where a pachinko machine is installed, the probability according to the business policy can be selected and set at each game store, for example, by considering the position of the pachinko machine 1, the interval between the other pachinko machines 1, and the like.

When the probability is set by the probability setting means 44, the counting means 39a is used as the random number generating means 39, and the set value is changed to change the total number of generated random numbers including the jackpot random number. The configuration of the generating means 39 and the change of the set probability are easy and simple.

Further, when the probability is set by the probability setting means 44, the key is inserted into the key switch 37 on the back side of the game board 5 to operate it. Only the staff in charge can set the probability, and there is no risk of injustice. For this reason, safety is improved.

Even if the high probability is set by the probability setting means 44, when the jackpot right is extinguished, the cancellation means 45 operates to return to the low probability, so that the temporary service until the jackpot right disappears can be stopped. it can. In other words, although the service is provided by a game store based on the content of the game, a variable service is possible. In some cases, a high probability of 1/50 is set. Consideration can be given flexibly.

In addition, even if a variable service is provided, the probability is returned after a jackpot has been generated and the right has been extinguished, so that the psychological desire of the player is not spoiled. In addition, all day pachinko machines have been closed
If the power of 1 is turned off, even if there is a pachinko machine 1 that has remained in a high-probability state without a jackpot
Since the 44 is forcibly returned from the high probability to the low probability, there is no need to return from the high probability to the low probability for each pachinko machine 1 at the start of business on the next day, and handling is easy. In addition, even if the pachinko machine 1 is set to high probability, it automatically returns to low probability in one day, so the high probability is one day at the longest, and the pachinko machine 1 with no jackpot on the previous day is concentrated on the next day. There is no capture.

FIG. 6 illustrates a second embodiment of the present invention,
Probability setting means 44 from a management machine 46 such as an external management personal computer
To set the probability.
That is, an instruction is issued from the external management device 46 to the probability setting means 44 of each pachinko machine 1, and the probability setting means 44 appropriately sets the probability of occurrence of a big hit according to the instruction. In this case, if an instruction is issued from the management machine 46 while the pachinko machine 1 is operating, the probability after that point changes. Therefore, it is also possible to issue an instruction during business hours of the day and use it as a time service. The conditions for the release by the release means 45 are the same as in the first embodiment.

Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment. The probabilities set by the probability setting means 44, the number of steps, and the like are merely examples, and may be other than the probabilities and the number of steps other than the embodiment. The release condition by the release means 45 can be determined as appropriate in relation to the configuration of the entire game. Further, in addition to the pachinko machine 1, the present invention can be similarly applied to a ball game machine such as an arrange ball machine.
