<p>PROBLEM TO BE SOLVED: To improve detection accuracy of deliberate vibration with a fraudulent purpose by simply and highly accurately suppressing a false detection with excessive vibration due to repetition of a plurality of times of allowable vibration and inhibiting a game progress from being stopped on the basis of vibration caused by opening of a front surface block.SOLUTION: A game machine is configured that a value of vibration intensity inference information is increased/decreased based on a detection state of a vibration detector, when the value of the vibration intensity inference information becomes a different value from an allowance vibration range between a reference value and an excessive vibration threshold, determines it as the excessive vibration and stops a game progress in response to the detection of a game medium that enters a profit offering part of the game board within a fraudulent benefit reception monitoring period started according to the determination of the excessive vibration. However, the game machine is configured not to stop the game progress in response to the detection of the game medium that enters the profit offering part in an open state of the front face block.</p> |
