PROBLEM TO BE SOLVED: To enable concentration on a game without interrupting the game even when game balls are not transferred from a lower tray to a box, when a large amount of prize winning balls are paid off for a short time. SOLUTION: The front of the lower tray 4 and walls of both sides are increased in height, and the distance between the front wall and an inner surface having a discharge port 7 is taken large so that the storing allowable amount is increased so as to store about 2000 game balls as payoff balls per great prize. The surface side of the front of the machine body is provided with a surface side ball extract passage 9 for causing the game balls to overflow from the upper surface side of an upper tray 3 to be guided directly to the upper part of the lower tray 4, whereby when the upper tray 3 is filled with the game balls paid off as prize balls, the game balls are guided to the lower tray 4 through a full-load passage on the back, and the game balls are caused to overflow from the upper tray 3 to a surface side ball extract passage ball receiving port 10 and discharged to the lower tray 4 from a surface side ball extract passage outlet 11 through the surface ball extract passage 9 to be stored in the lower tray 4.
