Roullete (pronounced “roh-LAHT”) is a casino game in which players place bets on the outcome of a spin of a wheel. The wheel consists of a solid wood disk slightly convex in shape, around which are metal separators or frets. Thirty-six of these compartments, painted alternately red and black, are numbered nonconsecutively from 1 to 36. A separate compartment, painted green (on European-style wheels) carries the sign 0. Two more green compartments on opposite sides of the wheel carry the signs 0 and 00 (on American wheels).
The game begins when a player places his or her bets on the table and the dealer reveals the value of each chip. Then the croupier, who is in charge of the game, spins the wheel. If the ball lands on a number, section, or color, winners who betted on that number, section, or color are paid according to their betting odds.
Roulette is one of the least popular games in American casinos, drawing far fewer players than slot machines, video poker, blackjack, and craps. But it still draws crowds in Monte Carlo and other European resorts. It is also an important component of many horse racing events.
