Abstract
A roulette playing device includes a hitting device for releasing a ball onto a circular runway which comprises a first rotatable roller disposed upstream of an outlet, a second rotatable roller opposed to the first roller and spaced therefrom by a distance smaller than the diameter of the ball, and a driver for rotating the first and the second rollers in opposite direction to each other. Such arrangement makes it easy to spin and release the ball and to control the spin of the ball. A release device for feeding a ball to the hitting device comprises a blower for sending forth air to the outlet through a release passage upstream of the outlet, and a feeder for feeding balls one by one to the release passage. Such arrangement enables the ball released on the circular runway to be accelerated thereon.
