The roulette was invented in 17 century by the French Scientist Blaise Pascal. He developed this device while attempting to find perpetum mobile. Later, one of his friends adopted this invention for gambling. But today the roulette wheel fascinated both scientists and players. Maybe you wonder why is that. Let me tell you the reason. If you look carefully you will see that the numbers are not situated one after another. They are arranged by this way to ensure the random element of the game.

There are two types of roulette wheels. The American one has 36 numbers plus zero and double zero. This increases the house edge with approximately 5,27%. The French wheel has only one zero and it is frequently used in the European casinos and those in South America. An interesting fact about the roulette wheel is that the total sum of all numbers is 666. This fact do not permit a perfect mathematical balance in the arrangement of the numbers. The producers of roulettes put the 0 and the 00 in an opposite manner. Moreover, the 0 is situated between two black pockets. Another trick is used to get the best distribution of high and low numbers: two numbers of the same color must equal 37.

The roulette wheel is an fascinating device with interesting history. One legend tell us that Francois Blacn really wanted to know the secret of the roulette and he sold his soul to the Devil. You may think that this man is imaginary, but he is not. He was the owner of the first casino in Monte Carlo.
