Roullete (French: “little wheel”) is a casino game in which bets are placed on a spinning wheel. A small ball is released in the opposite direction of the revolving wheel, and players make bets concerning which red or black numbered compartment the ball will come to rest in. The game emerged in the 18th century at the casino houses of Europe.
A roulette wheel consists of a solid disc slightly convex, around which are metal separators called frets or pockets, and on which croupiers place chips before each spin. Thirty-six of these compartments are painted alternately red and black, and numbered nonconsecutively from 1 to 36. There is also a green compartment numbered 0 on European-style wheels, and two additional green compartments numbered 00 on American roulette wheels.
Before the wheel is spun, a dealer clears the table of losing bets and pays the winners, then announces “no more bets!” This gives players a moment to decide whether they want to place a new bet before the ball is thrown. Generally speaking, players should start by placing outside bets, which offer lower odds than inside bets but higher payouts if successful.
Many systems have been developed for playing roulette, some easy and some complicated. However, as with any gambling game, a player must understand that it is primarily a game of chance and that there are no guaranteed systems for beating the maths. A quick Google search will return millions of roulette betting systems – some of them easy to use, others not so much. The best advice is to learn about the game, play it for fun, and walk away if you are not winning.
