PROBLEM TO BE SOLVED: To avoid such an invalid state of winning as no delivery of prize balls follows after a winning shot ball, in employing one-way communication from a game control means to a delivery control means. SOLUTION: Information capable of specifying the number of balls which are not yet delivered, out of prize balls to be delivered following winning are counted by counters A-C and a non-delivery winning ball counter on the side of a game control microcomputer. When the counting value of these counters reaches an upper limit value, error treatment 5 (S104) is given to stop shooting balls and one-way information communication from the game control microcomputer to a delivery control microcomputer is employed.
