Abstract
A roulette playing device comprises a release opening for releasing a ball. The opening is formed in a circular wall at a position higher than the level where the ball runs on the outermost circumference thereof. The circular wall is preferably tilted from a vertical plane toward a roulette wheel. Such an arrangement prevents the ball from running astray and dropping into the release opening. The roulette playing device further comprises ball sensors for detecting the ball running on the circular runway, an average speed detector for detecting the time the ball takes to run between two of the ball sensors, and a control device for outputting an instruction for prohibiting any more betting when the detected value by the speed detector reaches a preset value. Such an arrangement enables the behavior of the ball to be detected accurately and NO BETTING operation to be timed stably, whereby roulette games are made more amusing.
