Abstract: A roulette game is provided wherein a ball is thrown from a rotary disk onto the ball rotating passageway and is successively subject to actions of the magnetic forces of a series of electromagnets arranged along the ball rotating passageway and gradually increases its speed. After the ball has been thrown, the direction of rotation of the rotary disk is reversed so that the rotating direction of the rotary disk is opposite to the rolling direction of the ball. After a predetermined time period has passed and the electromagnets are deenergized and the rotary disk coasts, the ball loses speed and moves from the rotating passageway onto the rotary disk and is finally caught and stopped in one of a multiplicity of pockets. Therefore, the roulette gaming apparatus gives an actual feeling which is substantially the same feeling as will be obtained when players play an actual roulette game.
