ABSTRACT:
To make it more difficult for system gamblers to predict their chances of successfully placing their chips, the number ring in roulette equipment is an independent component that rests on the bottom of the bowl and can be angularly displaced from outside against inherent resistance. The ring is re-adjusted from time to time by the casino personnel to contaminate the probabilities.
