A roullete game is played on a roulette wheel that has 38 pockets, with 18 red and black and one or two green divisions numbered 0 (and 00 on American tables). Each number alternates between red and black.
Players place bets on the table by putting chips on a betting mat. Once the dealer announces “no more bets,” losing bets are cleared and winners are paid.
Origins
There are many fanciful stories about the origin of roulette, including that it was invented by 17th-century French mathematician Blaise Pascal as part of his quest to create a perpetual motion machine. However, it is believed that modern roulette evolved gradually over the course of around a century from its introduction, with various rules being combined and adapted. Many believe that the game was influenced by the Italian board game biribi, in which players bet on a layout of numbered squares.
Other theories suggest that the game originated in Rome, where Roman soldiers played games that were fairly similar to modern roulette. Another theory is that the game evolved from a wheel used in carnival games, which were popular during this period. Still others think that the game was based on a game that involved spinning shields that had symbols written inside of them.
