Roullete, meaning “little wheel,” is a casino game in which players place bets on the number or pocket the ball will land in on a spinning wheel. They may choose to wager on a single number, various groupings of numbers (inside bets), red or black, odd or even, or a combination of these choices. Each bet has its own payout odds based on probability.

The House Edge

In American-style roulette the wheel has two green compartments labeled 0 and 00, which give the house its advantage over European-style wheels. This edge is a result of the 0 and 00 not being considered part of the high or low groups on the betting layout. If the ball lands in one of these compartments, all outside bets lose.

The Dozens Bet: Also known as douzaine in French, the dozens bet places your chips on either the first dozen (1-12), the second dozen (12-18), or the third dozen (18-36). You must make at least two of these bets to win. If you win, the payout is 2-1. The Odd or Even Bet: Known as impair et pair in French, this bet consists of placing your chips on either the 18 odd numbers or the 18 even numbers. This is another even money bet and pays out 1-1.
