Roulette is a casino game that combines the excitement of chance with the thrill of gambling. It is a popular table game played at casinos worldwide. It has a variety of bets, including multiple groupings of numbers, whether the number is odd or even, and the color red or black. The game is played on a wheel that consists of a spinning disk with divisions around its edge, each of which is numbered nonconsecutively from 1 to 36 in alternating red and black. The wheel also has a green division that is numbered 0.
There are several variations of the game, all of which are available in online casinos. The most popular versions are European and American roulette.
The European version of the game is a favorite among players because it has a lower house edge than its counterpart, American roulette. It has a single zero pocket that reduces the house edge to 2.7%. This makes it a good choice for newcomers to the game and for high rollers who prefer to bet larger amounts.
Another variation of the game is French roulette. The game is a hybrid of the European and American roulette variants. The main difference between these two versions is that the European version has a single zero pocket, whereas the American variant has a double one.
Before the wheel is spun, a player places chips on a betting mat, indicating the location of the chips and the bets they wish to make. If the ball lands on the winning number, the croupier distributes the chips to the winners.
