PROBLEM TO BE SOLVED: To improve smoothness of a game progress when an approaching flow-down state occurs, without neglecting a measure against a fraudulent act, in a game machine.SOLUTION: In a game machine which determines whether or not a game medium flows down abnormally on the basis of change in combinations of detection states of the game medium by upstream side detection means and downstream side detection means, the change in combinations of detection states of the game medium by the upstream side detection means and downstream side detection means is detected and, on the basis of the detection, it is determined whether or not the change in combinations of the detection states is a change in accordance with a predetermined permissive state change corresponding to a normal state change and an approaching flow-down state. |
