Roullete is one of the world’s most popular casino games, offering glamour and excitement to gamblers everywhere. The game is simple, with players betting on what number slot they will land in after the dealer spins the roulette wheel. Though largely based on luck, the game has a surprising depth of strategy for serious betters and can provide high rewards for players with the right knowledge.

The game is played on a table with a numbered map of the numbers and various groupings of the numbers, and on which are placed chips of different colors to indicate the bets being made. In the center is a revolving dishlike device called a roulettewheel into which a ball is spun to rest finally in one of the 37 or 38 compartments, marked alternately red and black (on European wheels) or with two green compartments labelled 0 and 00 (on American wheels).

While there are many theories about the game’s origin, the roulettewheel was most likely designed by 17th-century French mathematician Blaise Pascal. Its popularity quickly spread throughout Europe, and in the 19th century it made its way to America. In the United States, roulette was developed into its present form in gambling dens and casinos around New Orleans and up the Mississippi to the west.

Before the first spin of the roulettewheel, each player places his or her chips on the table, indicating what bets are being made. The dealer then clears the table of losing bets and distributes new chips to winning players. Between spins, a player may give his or her money to the dealer by placing it on the table and asking for “color”; the dealer will then give the player coloured chips equal to the value of the amount given. Winning bets are still the player’s property until a request is made to withdraw them, at which time the payout is calculated and the winning chips are removed from the table.
