Gaming machine with a feedback control loop to ensure random selections by using a countervailing bias

Image Number 3 for United States Patent #7891664.

The invention relates generally to wagering games and, more particularly, to a gaming machine which determines game outcomes with a mechanical selector mechanism. Wagering games with game outcomes produced by a mechanical mechanism have not been widely accepted. Mechanical gaming machines are susceptible to bias from both inherent manufacturing defects and wear related degradation. Because gaming machines must meet regulatory required payback percentages, deviation from random operation may jeopardize the gaming machine's license. To overcome bias that may cause operation of the gaming machine outside its regulatory approved technical specifications, a feedback control loop can be implemented in the gaming machine to detect and correct bias as it occurs.
