Roulette is a game based entirely on chance, and is played by placing chips on a betting mat. After players have placed their bets the croupier throws a ball into a spinning wheel.
The wheel contains thirty-six compartments, alternately colored red and black and numbered 1-18 in a nonconsecutive pattern. In addition, there is a green zero on American wheels.
There are a lot of different stories about the origin of roulette. The most widely held one is that the game was invented in the 17th century by physicist Blaise Pascal. He stumbled upon it as part of his attempts to create a perpetual motion machine and was amazed at how easy it was to win. The wheel itself wasn’t introduced until a century later, but by then it had already become a staple of Paris’ gambling scene. Other theories about the game’s origin include that it was based on an ancient Chinese board game, or that it was brought to France by Dominican monks. However, none of these theories are particularly convincing. Ultimately, it seems most likely that roulette was derived from the older games hoca and portique and that it eventually achieved its modern shape with the addition of a single zero.
The odds of winning roullete vary depending on what type of bet you place. Outside bets have higher payouts, but lower chances of winning than inside bets. One of the more risky wagers is the split bet, which pays 17-1 if you’re right about two numbers. Another is the street bet, or a transversal in French. This involves placing chips that straddle the line between two rows of numbers and offers a pay-out of 11-1.
