The Odds of Roullete


Roullete is a game of pure chance, with no fixed rules and the result determined by randomness. A randomizing device, such as a spinning top or dice, is used to determine the outcome of a round. Some games of chance also have a skill element, such as roulette.


Roullete’s origins are thought to be in France, where it was invented by Blaise Pascal, a mathematician. His intention was to create a perpetual motion machine. Pascal incorporated elements of other games, including roly-poly and even-odd, to come up with the most popular game we know today.

While its exact origins are uncertain, there are several different theories regarding its origins. Some claim that the game originated in the Middle Ages. In fact, some believe that the game originated in France, where monks developed a game that cured their boredom. Dominicans also claim to have brought the game from China. Yet others believe its origins are far more ancient.

Special bets

You can place a variety of special bets on the Roullete wheel. One of the most common types is the even-money bet. This bet is an excellent choice if you are new to the game or would like to bet on a number that will win. When you place an even-money bet, you get your money back even if the ball lands on a 0 for the second time. The house edge on even-money bets is 1.35%.

Other special bets include the French bets. These bets are made using one chip and cover a group of numbers. These can be complex, though, and require players to announce their bet. A live dealer will then confirm whether the player made the right bet.


The odds of roulette are based on the casino’s rules, which tend to tilt the advantage in favour of the house. Therefore, it is important to know the odds before playing the game. Although some people confuse odds with probability, these two are very different. Odds refer to the ratio between your chances of winning and losing. They are never expressed as percentages but are presented as pairs of numbers.
