Roullete is a casino game that involves spinning a ball around a wheel to land in one of the numbers on a table. The game has become a popular attraction at many casinos and can be played with varying stakes depending on the size of the wager. The rules are simple and based on truth rather than fiction, which makes it a thrilling game of chance. There are some strategies that can be employed, but they should not be taken as gospel since the game is largely a matter of luck.

A roulette wheel consists of a solid wooden disk slightly convex in shape with metal partitions (called separators or frets by croupiers) that form pockets where the ball can land. Thirty-six of these compartments, painted alternately red and black, are numbered nonconsecutively from 1 to 36. On European-style wheels there is an additional green compartment numbered 0, and on American tables there are two extra green ones numbered 00.

Players make their bets by placing chips on a betting mat, the precise placement of which indicates the bet being made. The bets on individual digits are known as “inside bets” and the bets on groups of numbers are called “outside bets”.

Before each spin, the dealer clears all winning bets and pays them accordingly. Then, the croupier throws a ball into a spinning wheel and the players watch as it bounces around the pockets until it lands in a number. The croupier then places a marker on the winning pocket and all bets are cleared.

Those who want to try their hand at the game should know that they must have a predetermined amount of money and not bet more than this. It is also wise to place the smallest bets, as these have the best chance of winning.

The simplest bet is the Street Bet, which consists of placing your chip(s) to straddle the line between any row of three consecutive numbers on the table map. This bet pays 1-1. Other outside bets include the Trio, which consists of placing your chip(s) at the end of any of the straddled rows. This bet pays 5-1. The final outside bet is the High or Low bet, which is a call that the ball will land in either the first 18 numbers on the table (1-18) or in the last 18 numbers (19-36). If the ball lands on 0 or 00, all bets lose.
