Roullete (or roulette) is a casino game of chance, played on a revolving wheel with numbered slots in which the ball must come to rest. Players bet on the color red or black, odd or even and other groups of numbers, and a number’s characteristics such as whether it is high or low. In addition, some players bet on a single number. All bets are placed on a special betting table before the wheel is spun. When the ball settles in a slot, it pays out the winning bet to the player.
The croupiers, or dealers, at the table handle the bets. They also determine if the bets are on winning numbers, called “inside” or “outside” bets. The croupiers are required to record each bet in a logbook. There are various rules governing the handling of these bets and some have been enacted to prevent cheating.
Depending on the casino, some online Roulette games are offered with live dealers. In these games, the bets are placed via the keyboard or mobile device and the croupier handles them in real-time.
The roulette wheel consists of a solid wooden disk slightly convex in shape with metal partitions, or frets, around its rim. Thirty-six of these compartments, painted alternately red and black, are numbered nonconsecutively from 1 to 36. On European wheels, one of these compartments is painted green and carries the sign 0; on American tables there are two green compartments labelled 00. The croupiers, or dealers, spin the wheel while the ball is being thrown onto it and then place it in one of the 37 compartments. If a player has bet on that number or on the color of its slot, they win.
