Roulette

A roulette wheel consists of a rotating disc with divisions around the edge that rotates around the bottom of a bowl. A ball is rotated around the outside of the bowl until the ball and wheel finally come to rest with the ball in one of the compartments.

The divisions around the wheel are numbered from 1 to 36 in a seemingly random pattern, alternating red and black. In addition, there is a green division numbered 0. Only at American tables there is a second additional green division numbered 0, and this is primarily why the American version of roulette is financially worse than the European game. Before the ball is rolled, people place bets on the number that comes up by placing chips on a betting mat. The exact position of the chips indicates which bet is being made. Roulette is a game of French origin and at a traditional table the French terms for betting are still used in English-speaking countries. However, most US tables use English terms and a slightly different matting style.
