PROBLEM TO BE SOLVED: To provide a game machine allowing a player to continue a game even when premium balls or rental balls are out. SOLUTION: When a game ball enters winning hole for delivering fifteen premium balls, '1' is stored in a winning ball number memory region 214c corresponding to the address 0FH of the fifteen ball delivery in a winning ball number table 214b stored in a RAM 216. After that, '1' is added to the winning number memory region 214c whenever a game ball enters the winning hole. A sub-CPU installed on a delivery control circuit board drives a premium ball unit to deliver premium balls according to the number of winning balls stored in the winning ball number memory region 214c. Since premium balls can be delivered in this way based on the number of winning balls stored in the winning ball memory region, it is not necessary to store winning balls. When premium balls and rental balls are out, the drive of the premium ball unit is stopped though the drive of a ball shooting motor is not stopped. Therefore, a game will not be suspended on the way, and a player will not lose interest in the game.
