Title: Game machine and memory medium
Inventor: KISHI ISAO
IPC: A63F7/02
Filed: 2000-03-16
Abstract: PROBLEM TO BE SOLVED: To provide a game machine allowing a player to continue a game even when a lower tray is filled with premium balls. SOLUTION: When a game ball enters a winning hole for paying out fifteen premium balls, '1' is stored in a winning ball number memory region 214c corresponding to the address 0FH of the fifteen ball paying out 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 pay out premium balls according to the number of winning balls stored in the winning ball number memory region 214c. Since premium balls can be paid out 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 a lower tray is filled with premium balls, the drive of a ball shooting motor will not be stopped though the drive of a premium ball unit is stopped. Therefore, a game will not be suspended on the way and a player will not lose interest in the game.
