A roulette game is modified by electronic circuitry, including a microprocessor, to determine which one of a set of numbered, red or black compartments receives a ball and displays the play results via a lighted, marked roulette table upon which stakes are placed. The invention includes light emitting sensors that are placed beneath the roulette wheel, each compartment of which has an aperture formed therein, to monitor the compartment by detecting light passing through the apertures. Timing marks placed on the wheel are monitored by detector circuitry to determine the direction of rotation and angular rotation of the wheel, relative to a predetermined position. A microprocessor receives the information provided by the sensors and detector circuitry to determine which compartment received the ball, calculates winning wagers, and illuminates the corresponding spaces of the roulette table to inform players of the results.
