[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 a predetermined jackpot symbol and a jackpot occurs, the probability of occurrence of the jackpot from the next time is switched to a high probability of about 10 times. There is a formula.

[0004]

In this type of pachinko machine, once a big hit occurs on the fluctuating symbol display means, a large number of games are provided to the big prize means while the big prize means repeats opening and closing operations thereafter. The ball wins and a great profit is returned to the player, especially in the case of the probability variation type, if a jackpot occurs with a predetermined jackpot symbol, it becomes a high probability state and the jackpot is likely to occur continuously The advantage is that the player can play the game while expecting a great return of profits.

[0005] On the other hand, the probability of occurrence of a jackpot is usually 1/250 to 1/45 of the number of changes of the changing symbol display means.

That is, the game mode control means 43 uses the random number from the first random number generation section 34 when the first game mode A is selected, and the second random number generation section 35 when the second game mode B is selected.
Random numbers from the random number generators 34 and 35 are changed between the first game mode A and the second game mode B to change the jackpot occurrence probability in the variable symbol display means 29. Random number lottery determination means to determine whether the random number is a jackpot random number
A function of performing control to make a determination at 36, a function of controlling the number of times of opening and closing of the special winning means 25 after occurrence of a big hit to 16 times in the first game mode A and nine times in the second game mode B, When the game modes A and B are selected, the game information related to the selection of the game modes A and B, such as the selected game modes A and B and the game conditions in the game modes A and B, is displayed on a liquid crystal display.
A function of displaying an image on the display 22 and a function of preventing the mode selection means 41 from selecting the game modes A and B during the fluctuation operation of the fluctuation symbol display means 29 and in the high probability state are provided.

Next, the operation of the mode selection type pachinko machine 1 will be described. In the pachinko machine 1, the game mode setting means 40 sets two types of game modes A and B of a first game mode A of a high risk and high return type and a second game mode B of a solid type. By operating the mode selection button 42 of the mode selection means 41, the player can select one of the two game modes A and B, and play the actual game in the selected game mode A or B.

That is, since the game mode setting means 40 is normally on the first game mode A side, the first game mode A
A player who wishes to play the game at the time may start the game in that state. However, if the player wishes to play the game in the solid second game mode B, the user operates the mode selection button 42 prior to the start of the game and selects the second game mode from the two game modes. Just select B.

The game mode control means 43 operates according to the selection result of the mode selection means 41, and the first random number generation means 3
3. The random number lottery judging means 36, the special winning control means 38 and the liquid crystal display means 22 are controlled. That is, since the random number emitting units 34 and 35 of the random number generating unit 33 always generate the random number according to the respective conditions, when the first game mode A is selected by the mode selecting unit 41, the first random number emitting unit 34 In the second game mode
When B is selected, the random numbers from the second random number emitting unit 35 are respectively validated, and the random number lottery determination means 36
The random numbers generated from 34 and 35 are controlled by lottery.

When the first game mode A is selected, the special winning control means 38 sets the maximum opening / closing frequency of the special winning means 25 to 16 times, and when the second game mode B is selected, the maximum winning number is set to 9 times. Set or limit. Therefore, when the first game mode A is selected, the probability of occurrence of a big hit in the variable symbol display means 29 is 1/380. Since the opening / closing operation is repeated up to the number of times, the game can be played while expecting a great return of profits with great risk.

On the other hand, when the second game mode B is selected, the probability of occurrence of a big hit in the variable symbol display means 29 is 1 /
200 and the first game mode A.
Even if a big hit occurs, the number of opening and closing of the special winning means 25 is reduced to a maximum of nine times. For this reason, the player who has selected the second game mode B has a very small difference between the winning and losing,
It is possible to play the game steadily while having fun without being particular about winning or losing.

Further, when the first game mode A is selected, the fact that the first game mode A is selected, and when the game conditions in the game mode are the second game mode B, the second game mode is selected. The fact that mode B was selected and the game mode
The game conditions at A and B are displayed on the liquid crystal display means 22, respectively.
For this reason, the player selects the game mode A or B selected by himself,
The game conditions in the game modes A and B can be confirmed, and the game can be enjoyed after the player understands and understands the game conditions.

At the time of the game, the player operates the firing handle 11 of the firing means 10 with the game ball placed in the upper plate 7 after appropriately selecting the game modes A and B. Then, the game balls on 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 21. 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 game board 5, the player wins the winning opening 24 or the like, or falls to the lower part of the game board 5, enters the out port 28, and passes behind the game board 5. When the game ball wins the starting means 23 and the starting means 23 detects the game ball, the random number emitting units 34 and 35 of the random number generating means 33 repeatedly generate a predetermined random number. The random number lottery judging means 36 draws a random number at the time the game ball wins, and determines whether the random number is a jackpot random number, and at the same time, the fluctuation processing means 37 outputs the symbol display portions 30 of the fluctuation symbol display means 29. Is changed for a predetermined time.

At this time, the fluctuation processing means 37 is provided in each symbol display section.
After changing the symbol 30, the variable symbol display means 29 is controlled so as to stop at a stop symbol corresponding to each of the jackpot random number reach random number and the off-random number according to the determination result determined by the random number lottery determination means 36. Then, if the random number is a jackpot random number, the stop symbol of each symbol display unit 30 stops at a jackpot symbol such as “7 / 7,7”. Stops at any other symbol other than the big hit symbol.

In the case of the first game mode A, the random number lottery judging means 36 selects a random number from the first random number generator 34 and determines whether the random number is a jackpot random number generated at 1/380. Judge at 36. In the case of the second game mode B, the random number lottery judging means 36 randomly selects the random number of the second random number generator 35 and determines whether or not the random number is a jackpot random number generated at 1/200. judge.

When the lottery random number in the random number lottery judging means 36 is a jackpot random number,
The game ball 25 is opened, and the game ball falling from the upper side along the game board 5 easily wins the large winning means 25. Then, when ten game balls are won in the special winning means 25, or when a predetermined time has elapsed since opening, the special winning control means 38 operates to operate the special winning means.
25 closes.

When a game ball which has been won while the special winning means 25 is open passes through the central special operation area 32, the special winning means
25 closes and then reopens. And the first game mode
In the case of A, since the special winning means 25 repeats opening and closing up to 16 times, the game balls can easily enter the special winning means 25, and a great profit can be returned to the player. In the second game mode B, the maximum winning means 25 is up to nine times.

When a game ball is awarded to the special winning means 25, the ball payout means 16 pays out the game balls in the prize ball tank 25 to the upper plate 7 at a ratio of 15 to one of the winning balls, and The profit according to the winning number is returned to the player. By the way, the maximum payout number of the game balls to be paid out by the ball payout means 16 when one big hit occurs is 2400 in the first game mode A and 1350 in the second game mode B.

As described above, by changing the operating conditions of the special winning means 25 according to each of the game modes A and B, it is not necessary to change the number of balls to be paid out by the ball payout means 16 for each of the game modes A and B. Control of the ball dispensing means 16 is easy.
Therefore, the game condition for each of the game modes A and B can be easily changed in combination with changing the jackpot occurrence probability in the variable symbol display means 29.

Even when the symbol of the variable symbol display means 29 becomes a big hit symbol, if the stop symbol is an odd symbol especially for probability variation, the probability variation means 39 operates to operate the first game mode A and the second game mode. Regardless of the game mode B, the probability of occurrence of a jackpot in the changing symbol display means 29 from the next time is 1/38.
Switch from a low probability of 0 to a high probability of 1/38. For this reason, in any of the first game mode A and the second game mode B, if a big hit occurs in an odd symbol, the probability of the big hit occurring again due to the probability change by the probability changing means 39 becomes very large, It can motivate players to play games.

When the lottery random number is out of order, the symbol of the variable symbol display means 29 only fluctuates for a predetermined time, and the special winning means 25 and the like do not open or close. Game modes A and B are
During the game, if the player operates the mode selection button 42 of the mode selection means 41, the game mode control means 43 can operate and select. Therefore, the player can continue the game by selecting one of the first game mode A and the second game mode B as needed, considering his own money that can be invested in the game. It is.

However, when the stop symbol of the variable symbol display means 29 is a big hit symbol and the stop symbol at that time is an odd symbol, the probability variation means 39 is activated to be in a high probability state. Mode selection button of means 41
Even if the player operates the game mode 42, the selection signal is blocked by the game mode control means 43 and the game modes A and B cannot be selected.

Therefore, the game is started in the second game mode B having a high probability of occurrence of a jackpot, and after the occurrence of the jackpot, the game is switched to the first game mode A to return the profit more than the original first game mode A. It can prevent aiming at. In addition, even when the fluctuation symbol display means 29 is performing the fluctuation operation,
Game modes A and B cannot be changed.

The random number generation means 33 includes a first random number generation part 34 for the first game mode A and a second random number generation part 35 for the second game mode B. One of the random number generators 34 and 3 among the unit 34 and the second random number generator 35
Since random numbers from 5 are selected and used, it is easier to calculate the design probability characteristics in the pachinko machine manufacturing stage than when changing the jackpot occurrence probability on a program using the same random number. Therefore, even when a complicated game configuration is adopted, the characteristic of the predetermined design probability can be easily maintained.

When selecting the game modes A and B, the player only has to operate the mode selection button 42 arranged on the lower front side of the front frame 4 so that the player can easily operate the game modes A and B by operating the mode selection buttons 42. Can be selected. The embodiment of the present invention has been described above, but the present invention is not limited to this embodiment.

For example, in the embodiment, the first game mode A
Although two types of game modes A and B, i.e., and the second game mode B, are illustrated, three or more types of game modes may be provided. In the embodiment, the game conditions in each of the game modes A and B are different in the embodiment from the probability of occurrence of the jackpot in the variable symbol display means 29 and the operating condition of the big prize winning means 25, but the number of balls paid out for one winning ball. May be changed for each of the game modes A and B. In short, for each of the game modes A and B,
It is enough if the game conditions change.

Further, the mode selection means 41 may be of any type which can be easily operated by the player, and the mode selection button
Other than 42 may be used. Mode selection button 42
Even if is used, the position may be any position such as the front edge of the upper plate 7 that can be easily operated by the player.

The starting means 23 during the fluctuation of the fluctuation symbol display means 29
When a game ball is detected, a predetermined number of detections are stored, and after the variable symbol display means 29 completes the variable operation, the pachinko machine which fluctuates the variable symbol display means 29 by the stored number. Then, when a predetermined number of detections are stored, the selection of the game modes A and B by the mode selection means 41 may be prevented by the game mode control means 43. In addition to the pachinko machine 1, the present invention can be similarly applied not only to a ball game machine such as an arrange ball machine, but also to other rotating game machines.
