What is Roullete?

Roullete (from French for little wheel) is a casino game in which players place bets on the outcome of a spinning roulette wheel. A small ball is spun around the wheel, and if the bet wins, the payouts are determined in a matter of seconds. The game is very simple to play and offers many betting options including single numbers, various groupings of numbers, colors red and black, and whether a number is odd or even.

Roulette originated in the 17th century and was adapted from older games like hoca and portique. Its modern layout and wheel structure were introduced in the 18th century. The game is widely popular in casinos and gambling dens worldwide.

The wheel consists of a solid wooden disk slightly convex in shape. Around its rim are thirty-six compartments painted alternately red and black and numbered 1 through 36 in a nonconsecutive pattern. A single green compartment carries the number 0 on European roulette wheels, while American roulette has two additional green compartments labeled 00.

Before each spin, the player places chips on a roulette table according to his or her desired bets. Once all bets have been placed, the dealer spins the wheel in one direction while rolling a ball in the opposite direction around the outside of the bowl. Once the wheel stops, the ball lands in one of the compartments.

The odds of winning a bet are determined by the number of red and black slots and the proportion of these that are occupied by single and double zeros. In addition, some numbers are higher or lower than others. For example, a number 13 pays 35 chips to the winner, while a straight bet costs 37 chips to win. Those who wish to increase their chances of winning can also choose to play a variation of the game with an extra rule known as the “en prison” rule. This means that an even-odds bet loses to a zero only half of the time, which can improve the house edge by as much as 1.3%. This version of the game is usually available at online casinos.
