PURPOSE:To maintain the number of balls in each island within a prescribed range and preventing the eccentric existence of balls in a shop by always grasping the number of balls in circulation and restricting the balls which are newly introduced when an upper limit value is exceeded and feeding balls when a lower limit value is not reached. CONSTITUTION:The number of balls which are discharged from a ball circulation passage is the total of the balls supplied into a pinball game machine 2 and the balls supplied for lending to a player from a between-machine ball lending machine 4, and the number of introduced balls is the total of the balls (winning-out balls + winning balls) hit by the player and the premium balls supplied into a premium ball counter 3a. The number of balls which exists on the island 1 can be calculated by adding the number of balls which is introduced into a ball circulation passage to the initial set number of balls which are fed into the island 1 at first and subtracting the number of discharged balls. Then, the number of balls which is obtained by subtracting the balls staying in a storage tank 10 and the ball circulation passage is stored in an upper part tank 9. When an upper limit signal is transmitted from the storage tank 10 and the island 1 becomes full of balls, a display means 15 is operated so that no premium ball is introduced, and the player is led to other island. While, if a lower limit signal is transmitted, the feed of ball is accelerated by an informing means.
