PROBLEM TO BE SOLVED: To provide a game machine capable of previously preventing a fraud deliberately getting many prize balls by inserting a piano wire or a 'cell plate' (a thin resin band plate) in a ball putout passage via an opening part of a ball receiving tray and accelerating the putout of winning balls. SOLUTION: This game machine is provided upper/lower ball receiving trays 17 and 18 in front of the game machine P, the ball putout passage 34 guiding game balls put out from a ball putout device 30 to the upper-part ball receiving tray 17, and an overflow ball passage 23 branched form the ball putout passage 34 and guiding the game balls overflown from the upper-part ball receiving tray 17 to the lower-part ball receiving tray 18. The ball putout passage 34 is disposed with a shutter plate 38 positioned in the upstream side of the branch part of the overflow ball passage 23, being slid by an electric driving source and opening/closing the ball putout passage 34, and the shutter plate 38 tightly closes the ball putout passage 34 in the constant state and, when the game balls are put out from the ball putout device 30, opens the ball putout passage 34 for putting out the game balls to the upper-part ball receiving tray 17.
