GAME MACHINE

PROBLEM TO BE SOLVED: To provide a game machine for suppressing an erroneous detection conveniently and highly precisely an erroneous detection with an excessive vibration due to the repetition of a plurality of allowable vibrations, and reducing a dependency of a game progressing state on the detection accuracy of a foul play.SOLUTION: A game machine is constructed: to increase and decrease the value of vibration decision information on the basis of the detection state of vibration detection means; to decide an abnormal vibration in the case, where vibration decision information takes a value different from a predetermined allowable vibration range; and to make different (the selection of counter C1 updating processing S436, S438 and S440) a difference renewal amount between a renewal amount corresponding to a vibration detection time and a renewal amount corresponding to a vibration non-detection time, on the basis of the discrimination (or the decision of decision processing S435, S437 and S439) by game progress state discrimination means, at the increasing and decreasing times of vibration decision information on the basis of the vibration detection by the vibration detecting means.
