What is Roullete?

Roullete, also known as roulette, is a casino game that involves a spinning wheel and a ball. Players place bets on which red or black numbered compartment of the wheel the ball will enter as it slows down and comes to rest. There are many different types of bets, and each pays out at different odds. The game evolved in the late 17th century, and it quickly gained popularity in casinos throughout Europe. Its modern layout and wheel structure emerged in the 18th century.

A roulette wheel consists of a solid disk slightly convex in shape, with thirty-six metal or wooden compartments around its edge that are painted alternately red and black and numbered nonconsecutively from 1 to 36. On European-style wheels, there is one extra green compartment marked 00, while American tables have two additional green zero compartments.

The wheel is spun in the direction of the rim’s rotation, and the small ball is released from a basket attached to the outside of the wheel. The balls used in professional roulette games today are made of resin, Teflon, or synthetic ivory, but they have the same appearance and feel as traditional ivorine ones. The material, size, and weight of the ball affects its behavior and the odds of winning. For example, a small, light ceramic ball will make more revolutions on the wheel track and jump more unpredictably before it lands in a number slot than a larger ivorine one.

When a player bets correctly on a number, he or she wins chips that are paid out in accordance with the table’s pay-out ratios. The player may also choose to wager on groups of numbers, called “outside bets,” which are generally cheaper than inside bets but have lower odds of hitting. If the player wins a round, his or her losing bets are cleared off the table, and the dealer returns the winning chips to the player. The croupier then starts a new round with the bets that remain on the table.
