Roulette was invented by a French mathematician named Blaise Pascal. Gamblers know Pascal as the inventor of roulette, but he is most well known for developing the theory of probability. Blaise was born in 1623 in Clermont, France. When he was 16 years old, Blaise came up with a theory for projecting numbers that impressed all the leading mathematicians of Paris. Blaise was not only a mathematician but he was also an inventor.

The theory eventually became known as the theory of probability. Pascal developed this theory while solving a problem posed by a French mathematician named Chevalier De Mere. The scenario was that two players had to end a game before it was finished even though one player was clearly ahead. The problem was dividing the stakes fairly while considering odds of each player eventually winning the game. It would be unfair to penalize the player who was ahead by dividing the pot evenly. It would also be unfair to give the entire pot to the player who is ahead at the time, because his victory is not certain. Pascal devised a formula for determining the probability that each player would win if the game had been played to its conclusion. The theory of probability is used in all facets of life today.

Blaise Pascal also attempted to make a perpetual motion machine. His experiments failed to produce perpetual motion, but in turn did produce the Roulettte wheel. While the Roulette wheel cannot spin on forever it owes its roots to Pascal.

Roulette played online has a wheel with numbered slots and outside colors just like on a traditional roulette wheel. The slots are numbered 0 to 36 in traditional roulette and 00 through 36 in the American version. The American version is played the same as European Roulette only the odds are not as good for player because of the extra slot. The outside of the roulette board is colored in bars of red and black. A metal ball is spun in the wheel and continues to circulate the wheel until it comes to a stop within a slot. In online Roulette you can bet on a single number or multiple numbers. This is called an inside bet. An outside bet is when you bet on either the color red or black. In roulette you can also bet on odd or even or high or low numbers.

The game of roulette starts with the spinning of the ball in the roulette wheel. The wheel rotates in one direction and the ball rotates in the opposite direction. The ball spins inside the wheel until it comes to rest in one of the slots. If the ball lands on your number or color, you win. The game pays $36 for every $1 bet. There are no bad bets as each number or color pays at the same rate. The houses only advantage is the zero or double zero. If there were no zeros on the wheel and roulette still paid 36 to 1 it would be an even money game.
