The Roulette Wheel

The name roulette comes from a French word and translates to ‘little wheel’. The origin of the roulette wheel can be traced back to France many years ago. In the 17th century, a French scientist improved the model, his name was Blaise Pascal and is known as the legend who greatly improved the roulette wheel. Blaise became known for his research and findings for a perpetual motion machine. In the year 1843, Frenchmen Francois Blanc and Blaise Pascal teamed up to introduce the single 0-style roulette wheel. This was created in order to play against various casinos, which were offering the traditional wheel with only single and double zeros.

In Roulette, there are two wheels – the European roulette wheel and the American roulette wheel. The differences are actually quite simple. One of the fundamental differences is the number of slots available for balls to land.

European Roulette Wheel

The European roulette has the slots from 1 all the way to number 36. It also has one zero slot (0), available for landing purposes. In the European roulette wheel, there are 18 red, 18 black colored combinations, and one green slot making it a total of 37 numbered slots. If you bet an equal amount on both red and black, you will win your money back 36/37 times if the result is either black or red. You will only risk loss if your bet falls on the green that is 1/37.

American Roulette Wheel

The American roulette wheel has an additional numbered slot – a double zero slot (00) for landing purposes making it a total of 38 numbered slots. For its colored combinations, the American roulette wheel has an extra double green / two colored green slots. It has the same 18 red and 18 black colored combinations, if you bet the same amount as with the European roulette you will lose the bet 2/38 times.

The effect of the House edge

One of the differences between the two roulette wheels is that the American roulette wheel actually has one additional slot as opposed to the European roulette wheel. This difference plays a big influence on the house edge. When it comes to American roulette, the winning odds are thus lower. The European roulette has a house edge of 2.70% in comparison to the American roulette of 5.26%.

Casino players all over the world prefer playing the European roulette than the American roulette due to better roulette odds and higher chances of winning. Many starter players will choose the American roulette in order to learn how to play.

However, when it comes to the roulette wheel that people prefer, it really depends on their own personal preferences. Depending on the rules used by the casino, when playing the European roulette there is one rule that attracts players which is called the “en prison.” This option is used for outside bets, if the ball happens to land on the zero then the bet will actually be left/locked for the next spin. What is appealing to most players is that once the bet does win in the next spin, the player will receive the wagered money. However if the bet does happen to lose the player gets nothing.
