Roullete is a casino game in which players bet on the outcome of a spinning wheel containing colored compartments. Bets may be placed on a single number, various groupings of numbers, whether the number is odd or even, or whether the numbers are high (19-36) or low (1-18).
Before each spin, players place their chips on the betting mat with specific positions indicating their choice of bet. Each bet type has different odds and payouts. A winning bet will leave the player with a certain amount of money depending on their bet and the house edge.
The roulette wheel consists of a slightly convex wooden disk with metal partitions around the rim. Thirty-six of these compartments, painted alternately red and black, are numbered consecutively from 1 to 36, with the addition of a green division (marked 0 on European wheels; American tables add an additional green zero compartment marked 00). A small ball is spun in the opposite direction of the spinning wheel, and bets are made as it slows down and comes to rest in one of the compartments.
Players bet against the “house,” or the casino, and can win by correctly predicting which of the numbered compartments the ball will land in as it comes to rest. Roulette has many variations, but most aspects of the game are identical to the original version that emerged in the late 18th century in the casinos of Europe. Roulette is a popular casino game for both online and land-based players, with the latter often being hosted by expertly trained croupiers. Roulette is also a part of many live dealer casino games where players can bet in real-time while the game is being managed by a professional. A popular system, the James Bond strategy, combines a variety of bets to give players the best chance of winning, although it requires a considerable bankroll to be effective.
