Abstract
A gaming apparatus in which a roulette wheel has a circular rim and a downwardly converging frustoconical bowl contained within the rim and joined thereto forming a track therewith for a roulette ball and a rotatable wheel head centered within the bowl at the bottom thereof and formed with a plurality of numbered compartments for receiving the roulette ball. An automatic roulette ball spinner has a pair of guide tubes directed oppositely to one another and positioned along the rim for directing the ball tangentially onto the track. The guide tubes have a roulette ball magazine communicating therewith including respective powered plungers for propelling the ball through the guide tubes. The powered plungers are randomly activated and, in addition, the propelling force of the powered plungers is randomly adjusted. The plungers are actuated either electromagnetically or pneumatically. Each guide tube communicates with the track by way of a respective bore formed in the rim with the outlet of each bore blocked by a pivoted arcuate flap biased into a closed position and displaceable into an open position by the ball propelled through the bore.
