PROBLEM TO BE SOLVED: To enable the installation of the counters of the game balls on each of the game machine islands by avoiding the shortage or the excessiveness of the game balls in the slave islands in a game parlor facility comprising the master island which has a large ball storage tank and the slave islands each of which has a mall ball storage tank (slave island tank) while being preconditionally replenished with the game balls from the master island. SOLUTION: The inter-island gutters herein used are an inter-island replenishment gutter 14 with which the replenishment of the game balls is carried out in the direction of moving the game balls toward the slave islands from the master island within the same group and an inter-island recovery gutter 15 which recovers the game balls in the direction of moving the game balls toward the master island from the slave islands within the same group. When the storage level of the game balls within the upper tank 13 to which the inter-island gutter is connected to discharge the game balls hoisted with the ball hoisting device 33 outside exceeds the prescribed storage level, a shutter 17 of the island recovery gutter 15 is controlled to be opened. A plate-like passage member 60 which makes the game balls overflowed from the upper tank 13 flow down into the slave island tank or a recovery gutter 34 below the island is provided on the top surface of each of the slave island tanks 31.
