It is for this reason that the American wheel is considered not as balanced as the European wheel. On the American wheel, there are many examples where this rule is violated. On a European wheel, this is only violated where the 5 sits next to the 10 (both low numbers). The wheels are also structured so that the low numbers (1-18) and the high numbers (19-36) should alternate as much as possible. On both wheels, the red and black numbers alternate around the wheel, although if you removed the zeroes, the American wheel would have consecutive reds and blacks.

The numbers are arranged in a different order on each wheel but there are some similarities in the patterns. On an American wheel you can expect to lose 5.26% (if you are interested in the mathematics of roulette, the video at the end will show you how these odds are calculated). On a European wheel you would expect to lose, in the long run, 2.7% of any money you bet with. This is important as it doubles the advantage for the casino. Notice that the American wheel has two zeroes. The two layouts are shown below.Īmerican roulette wheel layout.

In fact, there are two different layouts. It was carefully planned and exhibits certain properties. Like a dartboard, the layout of a roulette wheel did not come about by accident. The idea is that you can make bets on the layout in a way that you are guaranteed to win. This is different to a game such as Blackjack where the probabilities change as cards are dealt.īut some believe that it is possible to exploit the way the roulette wheel, and the betting cloth, is laid out to give themselves an advantage. Each spin is an independent trial and, in the long run, the casino will win. What Einstein actually meant was that there is no mathematical trick that can help you win at roulette. Or you can find a biased wheel that makes some numbers more likely to come up. In fact, you can use Einstein's specialist subject, physics, to help you win. Although I wouldn't normally question Einstein, this statement isn't true.
