Roullete is a casino game with a long and storied history. It was invented in the 17th century by a French mathematician and became a popular pastime in gambling dens and casinos across Europe.
It is a game of chance based on a spinning wheel with red and black pockets, and also the numbers 1 to 36. The rim of the roulette wheel contains metal compartments or “frets” that are alternately painted red and black, with a single green compartment on European-style wheels and two green ones on American-style wheels marked 0 and 00. There are symmetries in the placement of the compartments around the wheel’s circumference that make betting a snap. Column- Placing chips at the bottom of one of the three ‘column’ sections pays out if the ball stops in that column. Dozen- Betting on the first, second or third ‘dozen’ of numbers (1 to 12, 13 to 24).
The game has several variations. The most popular is European roulette which is available at both physical and online casinos. It offers greater winning probabilities than its American counterpart thanks to its single zero pocket which dramatically reduces the house edge. The European version of the game also features a ‘la partage’ rule that allows players to recoup half their even chip bets if the ball lands on 0.
