BACKGROUND OF THE INVENTION
The present invention relates to a pachinko gaming machine in which a gaming state changes when a game ball stops at a stop.
[0002]
[Prior art]
For example, “333”, “777” with a predetermined probability after the ball is won at the starting opening and the symbols, such as numbers and symbols, are variably displayed on the symbol variation display so as to flow in a moving image. When all three rows are in the same pattern, a special gaming state (big hit) occurs, and the open / close door of the variable winning device (big winning opening) is continuously opened by the operation of the solenoid, making it very easy to hit the ball Thus, there are known pachinko machines that can acquire a large number of prize balls and bring a lot of profits to the player. In addition, the probability of occurrence of the special gaming state as described above is normally set to about 1/250. However, for example, when the number is equal to “777”, the probability is 1 after the special gaming state ends. Pachinko machines that change with a high probability of / 20 are also conventionally known.

[0011]
Next, the operation of this pachinko machine will be described. In this pachinko machine, when a game ball that is released by a player in the game area of the game board 1 wins the starting port 3, a random number is acquired and a plurality of symbols are displayed on the symbol variation display 2 in three rows. By displaying the fluctuations so as to flow like a movie, and determining the acquired random numbers, jackpot symbols such as “333” and “777” are displayed on the symbol fluctuation display 2 with a predetermined probability (usually a probability of 1/350). It is displayed and a special game state is generated, or the game is lost without displaying these symbols. When the special gaming state is entered, the open / close door 5 of the variable winning device 4 is continuously opened by the operation of the solenoid 35, and the game ball enters the variable winning device 4 very easily. It is possible to acquire a prize ball and bring many benefits to the player.
[0012]
Further, when a game ball that has been bounced by the player flows into the ball receiving port 9 and is guided onto the stage 14 as described above, the game ball 15 moves on the stage 14, and the three stopping portions 12 a, It stops on either of 12b and 12c, or is discharged onto the game board 1 from the front edge of the stage 14 without stopping. And when a game ball stops in the stop part 12a, 12b, 12c, the game ball is detected by detector 13a, 13b, 13c, respectively. For this reason, as illustrated in the flowchart of the probability setting routine in FIG. 8, in the initial state, the probability is set to 1/350 by step a. For example, when the game ball stops at the stopping portion 12a at the left position, By going through steps b and c, the probability is changed to 1/200, and when the game ball stops at the stopping part 12c in the right position, the probability is changed to 1/200 by going through steps d and e. When the game ball stops at the stopping part 12b in the center, the probability is changed to 1/100 through steps f and g. Such a setting change can be easily performed by increasing or decreasing the setting of a random number that brings about a special gaming state.
[0013]
Therefore, the player expects the game ball to be stopped at an advantageous stop as much as possible, and knows or infers the occurrence probability of the current special game state by looking at the stop state of the game ball. it can. It should be noted that the solenoid 24 of the ball discharge device 18 is activated and the detectors 13a, 13b, and 13c are moved up due to a certain period of time after stopping, a special gaming state, or other factors. The probability is returned to the initial set state by discharging the game balls that have been stopped at the stop portions 12a, 12b, and 12c.
[0014]
On the other hand, in the flowchart shown in FIG. 9, the probability of occurrence of a special gaming state is changed in accordance with the number of the stopping parts where the game balls are stopped. Is stopped, the probability is set to 1/100, and when the game ball is stopped at two stops, 1/200, when the game ball is stopped only at one stop 1/300, or 1/350 when no game balls are parked. Also in this case, the ball discharge device 18 is actuated after a certain time elapses to discharge the stationary ball, thereby returning to the initial setting state.
[0015]
In this embodiment, the probability of occurrence of the special gaming state is changed by stopping the game ball so as to change to an advantageous or unfavorable state for the player. It can also be set to change to an advantageous or unfavorable state by changing it, changing the number of paid-out prize balls, or changing the maximum number of continuations (number of rounds) when a special gaming state occurs it can. It is also possible to set the game ball to be in an advantageous state by opening the predetermined winning opening when the game ball stops and making it easier for the game ball to win.
In the above embodiment, the mechanical switch is used for detecting the stop of the game ball, but it is needless to say that the presence or absence of the game ball may be detected by an optical sensor, a proximity switch, or the like.
[0016]
In addition, you may make it display description of the fluctuation | variation of the probability, etc. when a game ball stops in each stop part on the symbol fluctuation | variation display 2. FIG.
[0017]
