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-and-ball game machine such as 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. Or after the game ball that has won the other prize means passes through the special operation area inside it,
There is a method in which a big hit right that is advantageous to a player is generated and a profit is returned by opening and closing a special winning means a predetermined number of times each time a game ball wins a specific starting means.

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,
There is a probability variation type in which the probability of occurrence of a jackpot from the next time is switched to a high probability of about 10 times. In this type of ball game machine, once a big hit occurs on the fluctuating symbol display means side, a large number of game balls win the big prize means while the big prize means repeats opening and closing operations, A great deal of profit is returned to the player, and in a probability-variable ball game machine, once a jackpot occurs, the state becomes a high-probability state, so that the jackpot is likely to continue. For this reason, there is an advantage that the player can play a game while expecting many return profits, and the player is popular and is now widely used in many game stores.

[0004]

In a conventional ball-and-ball game machine, a random number generating means sequentially generates a jackpot random number, a reach random number, and other outlier random numbers at a predetermined probability.
When the starting means detects a game ball, a random number control method is used in which the random number generated by the random number generating means is randomly selected by the random number lottery means, and the symbol of the variable symbol display means is varied by the variation processing means for a predetermined time in accordance with the random number. ing.

Therefore, apart from whether or not a big hit actually occurs during the game, the starting means detects the game balls for the set number of times, and the variable symbol display means changes the number of times of the change for the set number of times. Is repeated, a big hit occurs with a predetermined set probability. However, the probability-variable ball game machine adopts a method of switching from low probability to high probability on condition of the occurrence of a big hit, so the player must keep firing the game ball until the first big hit occurs In some cases, it takes a long time for a monotonous jackpot to be monotonous, and during that time, the game may be interrupted or abandoned due to the impatience.

That is, the conventional probability-variable ball game machine has a drawback that the game content is flat and monotonous, has little change, and lacks a sense of urgency. In particular, some ball game machines, such as CR machines, have set the probability of jackpots to be reduced to about half that of ordinary machines, making it increasingly difficult to generate initial jackpots. Has become. The present invention
In view of such conventional problems, it is an object of the present invention to provide a ball game machine capable of providing a wide range of game characteristics and configuring a game having an excellent interest, and enabling a player to enjoy a game with a variety of changes and a sense of urgency. I do.

It is attached detachably. An opening 13 is formed in the back mechanism plate 12, a prize ball tank 14 and a prize ball tank rail 15 are provided on the upper side, a ball payout means 16 is provided on one side, and a passage unit 17 and the like are provided on the lower side. Have been.

The opening portion 13 is fitted with a back cover 18 and a winning ball tank 19 which are mounted on the back side of the game board 5 vertically close to each other. A control box 20 is detachably attached to the back cover 18 from the back side, and the control box 20 houses a control board. As shown in FIG. 3, a guide rail 22 is annularly mounted on the game board 5, and inside the guide rail 22, a variable symbol display means 23, a starting means 24, an upper winning opening 25, and a left winning opening 26 are provided. , Right winning opening 27, specific winning means 28, middle winning opening 29, type 3 starting means 30, large winning means 31, out opening
32 are provided respectively.

The starting means 24 is of a pass type for detecting a game ball passing from the top to the bottom in front of the game board 5, and is arranged between the variable symbol display means 23 and the big winning means 31. The changing symbol display means 23 has three symbol display portions 34 in the left and right direction, and when the starting means 24 detects the passing of the game ball, the display symbols of each symbol display portion 34 fluctuate for a predetermined time by a kind of random number processing. It is configured to be. In addition, each symbol display part 34 switches each symbol of 0-9 and A to red and green, for example, and displays it.

The special prize winning means 28 is configured to be effective 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.
For example, when the probability of occurrence of a jackpot is 1/250, a random number from 0 to 249 is repeatedly generated. Each of the random numbers generated by the random number generation means 36 is set to one of a big hit random number, a small hit random number, and a mode random number, as well as a reach random number and other outlier random numbers. The mode random numbers are used for changing the probability from a low probability to a high probability.

Reference numeral 37 denotes random number lottery means. When the starting means 24 detects a game ball, the random number value of the random number generation means 36 at the time of the detection is randomly selected. Reference numeral 38 denotes a random number determination unit which determines whether the random number drawn by the random number selection unit 37 is a jackpot random number, a small jackpot random number, a mode random number, a reach random number, or a missed random number. After each symbol display part 34 of the symbol display means 23 stops at the big hit symbol, the specific winning means 28 is activated,
The special operation area 35 is configured to be operable.

Numeral 39 is a fluctuation processing means. When the starting means 24 detects a game ball, each symbol display section 34 of the fluctuation symbol display means 23 is displayed.
Is changed for a predetermined time, and when the random number drawn by the random number lottery means 37 is a jackpot random number, the stop symbol of each symbol display section 34 becomes a jackpot symbol of "7.7.7". Jackpot random numbers drawn by lottery means 37,
The stop symbol of each symbol display unit 34 is controlled according to the small hit random number, the mode random number, the reach random number, and the out-of-order random number.

In the case of the reach random number, among the three symbols displayed on the symbol display unit 34, a reach symbol different only in the symbol displayed on the right symbol display unit 34 is displayed.
In the case of the mode random number and other outliers, all the outboard symbols of the three symbol display units 34 display different outlier symbols. In the case of the small hit random number and the mode random number, the color of the design or the background is changed and displayed as another outlying design, so that it can be distinguished from the other outlying design.

Reference numeral 40 denotes a special winning control means.
When the game ball passes through the special operation area 35 and the game ball passes the third type starting means 30 according to the big hit random number or the small hit random number when the game ball passes through the special operation area 35, the big winning means 31 is opened and closed a predetermined number of times. It is made to let.

That is, the special winning control means 40 is provided with a big hit right generating means 41 and a small hit right generating means 42.
The jackpot right generation means 41 is for generating a jackpot right advantageous to the player when the random number lottery means 37 draws a jackpot random number and the stop symbol of the variable symbol display means 23 becomes a jackpot symbol, Each time a game ball enters the three-type starting means 30, the large winning means 31 is opened and closed up to 16 times.

The small hit right generating means 42 is a random number lottery means.
37 is for generating a small hit right which is advantageous to the player when the random number for the small hit is drawn.
Each time a game ball enters, the special winning means 31 is opened and closed up to twice. The large winning means 31 is configured to close when ten game balls have won in one open state.

Numeral 43 denotes a probability varying means. When the random number lottery means 37 selects a mode random number, the probability of generating a big hit random number and a small hit random number is reduced from 1/250 to 1/25 to 1/2.
The probability is switched to a high probability of about 1/50, and is returned to the low probability when the random number lottery means 37 selects a large random number or a small random number after the high probability state.

Next, the operation will be described with reference to the flowchart of FIG. When the power of the pachinko machine 1 is turned on, the random number generation means 36 constantly counts clock pulses repeatedly to generate random numbers from 0 to 249. At the time of the game, the operating handle 11 of the firing means 10 is operated in a state where the game ball is put in the upper plate 7. Then, in conjunction with the firing operation of the firing means 10, the game ball of the upper plate 7 is moved to the firing position of the firing rail by one.
The game balls are supplied one by one, and are hit with a hitting hammer and sequentially fired along the guide rails 22 on the upper side of the game board 5.

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 from above to below, and the starting means 24 detects the game ball (step S
1) Since the random number generation means 36 constantly repeatedly generates random numbers from 0 to 249, the random number lottery means 37 selects the random number at that time (step S2), and at the same time, the random number is determined by the random number determination means 38. Big hit random number, small hit random number,
It is determined which of the mode random number, the reach random number, and the out-of-range random number (step S3), and the symbol of each symbol display section 34 of the variable symbol display means 23 is varied by the variation processing means 39 (step S4).

At this time, the fluctuation processing means 39 is connected to each symbol display unit.
After the symbol 34 fluctuates for a predetermined time, it fluctuates so as to stop at a stop symbol corresponding to each of the big hit random number, the small hit random number, the mode random number, the reach random number, and the off random number according to the determination result determined by the random number determining means 38. The symbol display means 23 is controlled. Then, for example, if the 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”, and if it is an outlier random number including a reach random number, etc., each symbol display unit 34 If the stop symbol is a symbol other than the big hit symbol, and if the random symbol is a small random number, it is displayed so as to be distinguished from other miss symbols. Note that the symbols on each symbol display section 34 stop sequentially from the left after a predetermined fluctuation time has elapsed.

The random number judging means 38 judges whether the lottery random number is a big hit random number, a small hit random number, or a mode random number (steps S5 to S7), and operates as follows according to the judgment result. When the lottery random number is a jackpot random number (step S5), the specific winning means 28 is activated (step S5).
8) If the game ball that has won the specific prize means 28 passes through the special operation area 35 (step S9), the jackpot right generating means 41 works to give the player an advantageous right (big hit state).
Occurs (step S10).

That is, if the game ball passes through the special operation area 35 of the specific winning means 28, thereafter, every time the game ball enters the third kind starting means 30 (step S11), the special winning means 31 is opened for a predetermined time. Then, the special winning means 31 repeats the opening / closing operation up to 16 times (step S13).
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 payout means 16 is provided for each game ball. Is 1
A total of 2400 game balls of 5 are paid out as prizes, and a great profit is returned to the player.

Also, when the judgment result is a small random number (step S6), the specific winning means 28 is activated (step S6).
14) If the game ball which has won the specific winning means 28 passes through the special operation area 35 (step S15), the small hit right generating means 42 works to return about 1/8 of the big hit profit to the player. (Step S16).

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 S17), the special winning means 31 is opened for a predetermined time. Then, the special winning means 31 repeats the opening / closing operation twice (step S19). For this reason,
As described above, 10 game balls win during one opening of the special winning means 31, so 20 game balls win while opening and closing twice, and payout means for each one of the game balls. 16 is 15
A total of 300 game balls are paid out as prizes.

Further, when the determination result is a mode random number (step S7), it is determined whether or not the current time has a low probability (step S20). If the probability is low, the probability changing means 43 switches the probability to the high probability from the next time (step S20). Step S21). Therefore,
Once the mode random number is drawn, the probability of generating the big hit random number and the small hit random number is from 1/250 to 1/25 to 1 /
Since the probability of generating a big hit right or a small hit right becomes very large, the number of times the variable symbol display means 23 is started until a big hit or a small hit occurs is reduced, and the player's I was impatient, frustrated,
Irritation can be prevented.

At the same time as switching from the low probability to the high probability, even if the stop symbol is the same departure symbol, such as the background color of the fluctuating symbol in each symbol display portion of the fluctuating symbol display means 23, another departure symbol is displayed. It is displayed so that it can be distinguished from the design. For this reason, the player who is playing the game while paying attention to the display symbols of the respective symbol display portions of the variable symbol display means 23 may be able to guess that a change has occurred in the game state due to the difference in the display, and the like. The game can be enjoyed while working.

Although the player cannot know the state of high probability, while playing the game while thinking about the timing of the occurrence of the jackpot, when the number of fluctuations of the fluctuation symbol display means 23 is relatively small, In the case of, the jackpot or small hit as expected by the player actually occurs, so the player feels
It is possible to play a game while having a sense of satisfaction, and it is possible to sufficiently arouse the player's desire for the game.

In addition, since the small hit right is provided in addition to the big hit right so that two kinds of right states can be obtained with the same probability, the player can get rid of the great profit by the big hit right even if tired. In addition, a small profit right generated with the same probability as the big hit right can receive a certain amount of profit return. Therefore, by coexisting both, the range of the game configuration is expanded, and an interesting and interesting game can be easily configured.

In addition, when the mode random number is randomly selected, the probability is changed from the low probability to the high probability by the probability varying means 43. Therefore, after the mode random number is generated, it is almost the same as the fact that the big hit right or the small hit right actually occurs. As a result, the range of game characteristics can be further expanded. Jackpot random number,
Since the small hit random number and the mode random number are each one, the cycle of random number generation by the random number generating means 36 can be shortened.
An interesting game that is difficult to capture can be easily configured.

Once the mode random number is randomly drawn during the game and the probability is high, a big hit right or a small hit right is generated thereafter, and after the right ends (steps S13 and S13).
19), it is determined whether or not the probability is high, and the probability is returned to the low probability (steps S22 and S23). In this case, since the profit is once returned by the big hit right or the small hit right, the player's willingness to play the game is not hindered. In addition,
When ending the game, the process ends after step S24. The embodiment of the present invention has been described above, but the present invention is not limited to this embodiment.

For example, a lottery of mode random numbers in addition to a lottery of big hit random numbers and small hit random numbers may be added to the condition for canceling the high probability to cancel the high probability even if no big hit or small hit occurs. good. Jackpot rights,
When the small hitting right is generated, the big winning means 31 may be opened and closed immediately after the lottery of the big hit random number or the small hit random number, and the content of each right is sufficient as long as it works for the player in an advantageous manner. is there.

The number of the big hit random number, the small hit random number, and the mode random number are preferably one in order to shorten the cycle of generating the random numbers, but two or more pieces can be provided. Further, the present invention can be similarly applied to a ball game machine such as an arrangement ball machine in addition to a pachinko machine.
