Roulette is a popular casino game which originated in France sometime in the 18th century. The game has since spread all over the world and is now a staple of casinos both offline and online. Roulette is a game of luck; the game is played with a spinning wheel with pockets marked with numbers and colors, a ball, and a table of bets. The player tries to predict the result by betting on a certain number or group of numbers. Each round, all bets are collected and the player who guessed correctly (or the "winner") walks away with the money.
