Abstract
A roulette lottery apparatus includes a roulette body configured to revolve about a rotation center line tilted about the vertical direction, in which plural pockets are arranged in the circumferential direction, a guide rail that guides a ball to any of the plural pockets, a ball release device that injects the ball into the guide rail, and a control unit that controls a timing of injecting the ball. The timing of injecting the ball is controlled at an angle unit smaller than 2π/N when N represents the total number of pockets. The object is to cause plural players to view the roulette lottery apparatus and to equalize probabilities that plural pockets win a game ball.
