<P>PROBLEM TO BE SOLVED: To provide a game machine capable of securing the smooth game progress. Ž<P>SOLUTION: In the game machine, the state of passage of game balls is discriminated based on the pattern of detection of game balls by a passage detecting means including a first detection part and a second detection part disposed at an interval narrower than one game ball in the direction of downflow of game balls in the downflow of a prescribed number of game balls through a plurality of pathways. In the game machine, whether the passage of game balls is in the normal state or not is determined for the respective pathways, and at the same time, whether the passage of game balls is in a serial state or not is determined. When the passage is in the serial state, the downflow of game balls in a pathway through which game balls pass in the serial state is suspended. Then, after termination of downflow of game balls through other pathways, downflow of game balls through a pathway is restarted so that the downflow of the prescribed number of game balls is completed.
