A roulette apparatus has a table, a roulette wheel mounted to spin about a vertical axis with respect to the table, the wheel having a plurality of ball receptor cups at the periphery thereof and having a hub portion and a rim portion. The hub and rim portions are displaceable axially with respect to each other between a "play" position and a "return" position, for forming a gap between the hub portion and the rim portion when the hub and rim portions are in the "return" position. A return channel is provided beneath the wheel, whereby when a ball has been projected onto the spinning wheel and has fallen into one of the cups, and the hub and rim portions have been displaced to the "return" position, the ball rolls from the cup into which it has fallen, rolls through the gap, and then falls to the return channel.
