Roullete is a casino game with an element of chance and a large house edge. It has a low following in the US, but is one of the top casino games in Europe, especially in Monte Carlo and other European resorts.

The game is played on a wheel with divisions around it that revolve and come to rest with the ball as the wheel spins. The numbers are numbered in a seemingly random pattern, alternately red and black, and there is also a green division numbered 0.

Roulette has one of the lowest house edges on American wheels but a higher house edge on European ones. The house edge on the European version can vary from 1.35 percent to 2.70 percent.

There are two ways to bet on the roulette table: by placing chips on the inside section or the outside section. The inside bets are on a single number or range of numbers, while the outside bets are on different groupings of pockets based on their position.

To place a bet on the roulette table, you must have a set of specially marked chips that can only be used at the particular table you are playing at. Each chip is worth a certain amount, which you tell the dealer when you are ready to cash in your bets.

A roulette wheel consists of a wooden disk with metal partitions around its rim. Its rim is slightly convex in shape and contains 36 compartments painted alternately red and black. Each compartment carries the letter 0 on European-style wheels and 00 on American-style wheels.

Whenever you have placed a bet on the roulette wheel, the ball will spin and come to rest in one of these compartments. The winning bet is determined by the position of the pocket in which the ball lands.

Some people have a knack for predicting the outcome of a spin. They might know which number will be next or which combination of numbers will be hit. Some have developed strategies that can help them win more money on a given spin. For example, they could predict whether the ball will land on a black or red pocket.
