On the other hand, when a hit ball hit into the game board 5 wins a prize in the normal winning lower, variable winning opening 8, or when the variable winning device 11 is in the open state, the hit ball hits the passage 1 of the cover member 13.
6 flows down, falls to the ball collecting 20 while being detected by the detection switch 17, and is discharged to the winning ball discharge passage 18. When the detection switch 17 detects a hit ball, the detection signal activates the pulse generation circuit, the output of which is sent to the counter circuit, and 13 pulses are given to the counter circuit. Then, the output from the counter circuit is given to the output control circuit,
The electromagnet 28 of the prize ball discharging device 23 is repeatedly excited and demagnetized a number of times according to the number of pulses, that is, 13 times, and the 13 prize balls are discharged into the prize ball discharge gutter 24 as described above.

The number of prize balls may be set to any number including one.

As described above, according to one aspect of the present invention, the hit ball enters the starting prize opening 10.
By making the number of prize balls released when a prize is won in a to 10c different from the number of prize balls released when a prize is won to the normal winning lower or the variable winning device 11, and thereby reducing the number of prize balls, a prize is won to the starting winning openings 10a to 10c. Even if the probability is made much higher, the game arcade will not suffer a huge loss. On the other hand, for the player, if the probability of winning a prize in the starting prize openings 10a to 10c is high, there will be many opportunities to change the display state of the variable display device 9, and the player will always be given a sense of expectation of entering the special prize game state and play the game.
