Roullete is a casino game in which players place bets on numbers or groupings of numbers. It is played on a wheel, which has divisions painted with red and black to indicate the different groups of pockets.
The wheel is made of a solid, slightly convex disk with metal partitions known as separators around the outside. These compartments are numbered from 1 to 36, nonconsecutively. On European-style wheels, a 37th compartment is painted green and on American-style wheels two green compartments are painted on opposite sides.
Roulette is a game in which the outcome of each spin is determined by a ball that rolls across a wheel and stops at a number on the outside of the wheel. A player can bet on any of the numbered pockets or groups of them, and can also bet on whether the ball will land in an odd or even pocket, or if it will land on red or black.
A table is located at the center of the wheel, and a dealer, called a croupier, sits in front of it. A betting mat, with the exact locations of the chips that represent each bet, is placed on top of the table.
Each chip represents a specific amount of money and cannot be changed to other types of casino chips, or used elsewhere in the casino. The dealer will mark the value of your chips on a wheel and parcel them out to you.
The house edge in a standard European roulette game is usually 2.70 percent, but can range from 1.35 to 5.26 percent depending on the particular type of wheel being used. In contrast, on an American wheel the house edge can be as high as 7.89 percent or as low as 2.63 percent.
Roulette is a fun and exciting casino game, but it can be very expensive. The odds of hitting a single number are very good, but the house edge is so big that it can make you lose money quickly.
