A game machine includes a main frame, a partition front slantingly mounted on a middle portion of the main frame. A collecting device is mounted onto an underside of the partition and multiple falling ball sensing units are mounted onto an upside of the partition. Multiple prize dispensing devices are mounted onto an internal panel of the main frame and electrically connected to a corresponding one of the falling ball sensing units. A control unit is secured on the main frame and an operational unit is disposed to an upper portion of the main frame, wherein the operational unit is electrically connected to the control unit. When starting a game, the operational unit firstly catches a ball and targets a selected falling ball sense unit, and then releasing the ball to the targeted falling ball sensing units for driving the prize the dispensing device.
