Roullete (or Roulette) is a casino game that involves spinning a small ball on a fixed-size wheel to determine a winner. The game was developed in the early 18th century in France, where it became a popular choice at gambling houses and casinos. There are many fanciful stories about the origins of this game, including that it was invented by 17th-century French mathematician Blaise Pascal or by a Dominican monk. The Roulette wheel consists of a solid wood disk slightly convex in shape, with metal compartments or “frets” around its rim. These compartments, painted alternately red and black, are numbered nonconsecutively from 1 to 36. A green compartment on European wheels, and two on American wheels, carry the sign 0.
Players place bets in the form of chips on various number groups or individual numbers. If their bet wins, the dealer announces the winning number and collects the losing chips (which go into the casino’s income), paying out the winnings to players. There are 10 different types of bets, with the highest win to stake ratio being on a single number, which pays up to 35 times your bet.
