Roulette is a casino game where players bet on a number or grouping of numbers. They place their chips on a betting mat with precise locations that mark the bet they are making.
The croupier then spins the wheel and the ball lands on a number, section or color. The winners are paid according to their odds of winning.
Origin
The exact origin of roulette is unknown. Many theories exist about its creation, including the claim that it was invented by 17th-century French mathematician Blaise Pascal as part of his quest to create a perpetual motion machine. Others say that it began in ancient China, where a game of chance was played using a board arranged into a square with numbers and the colors red and black. It is also possible that the modern game of roulette was introduced to France by Dominican monks who traveled to China. Regardless of its origin, roulette quickly became popular in France and around the world.
