Abstract: A method includes receiving, by a motion sensing controller, two calibration wireless transmissions that were transmitted from two different wireless emitters that are fixedly positioned to two different components of a wagering game system during calibration. The method includes receiving, by the motion sensing controller, two gameplay wireless transmissions that was transmitted from the two different wireless emitters for tracking of the wagering game play of the wagering game. The method includes determining a calibration movement difference between the two calibration wireless transmissions and determining a gameplay movement difference between the two gameplay wireless transmissions. In response to the calibration movement difference and the gameplay movement difference being unequal, outputting an indicator of at least one of a component movement and distortion of one of the two different gameplay transmissions.

Abstract: A gaming machine includes at least one cylindrical mechanical reel mounted in a cabinet.
