<p><P>PROBLEM TO BE SOLVED: To improve smoothness of the progress of the play when a state in which game media flow close to one another occurs without neglecting measures against fraudulence in a game machine. <P>SOLUTION: The game machine determines whether downflow of game media is abnormal or not based on the change of combination of detected states of game media by an upstream detection means and a downstream detection means. The game machine is configured to detect the change of combination of detected states of game media by the upstream detection means and downstream detection means, and to determine whether the change of combination of the detected states is caused by a regular state change or a prescribed allowable state change corresponding to a close downflow state. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
