PROBLEM TO BE SOLVED: To provide a game machine capable of preventing a fraud fraudulently operating the rotation of rotary reels and preventing a failure when a rotation speed gets to an abnormal range by an inferior controllability or the like. SOLUTION: This game machine includes: a count means (120) counting the number of pulse signals output to a stepping motor (64) after detecting an index (47) and resetting the count number when detecting the passing of a next index (47); a reel location determination means (130) for determining the present location of a rotary reel (40) based on the count number counted after detecting the index (47); and an error detection means (140) defining a range of an allowable count number within a predetermined range and, when the count number from the detection of this index (47) to the detection of a next index (47) is out of the range of the allowable count number, outputting an error signal.
