PROBLEM TO BE SOLVED: To provide a game machine capable of preventing a player from being given the sense of disorder in the progress of a game as much as possible even if the monitoring time is prolonged. SOLUTION: A variable winning device is disposed in a game ball passing area between a movable member and a special winning hole, and comprises a winning detecting means for detecting entrance of a game ball into the variable winning device and a discharge detecting means for detecting discharge of a game ball from the variable winning device. A control means comprises a remaining ball determining means for determining the presence of game balls remaining in the variable winning device in a preliminary game state based on the result of detection of game balls by the winning detecting means and the discharge detecting means, a remaining ball error determination time setting means for setting the remaining ball error determination time whenever entrance of a game ball is detected by the winning detecting means, and a remaining ball error determining means for determining a remaining ball error if the remaining ball error determination time elapses before the number of game balls remaining in the variable winning device becomes zero.
