The key difference between the American roulette is, as we have already mentioned, there are two additional sectors at once: ordinary zero and double zero. With the advent of this additional sector, some additional betting options appear. So, for example, only in an American roulette is the opportunity to put on the first five numbers: Zero, double zero, one, two and three. The payment at such a rate is very impressive and is 6 to 1, and the mathematical probability of winning is 13, 16%. But few know that the bet for the first five numbers is the largest House Edge indicator of all possible. If for all other bets in the American roulette the advantage of the casino is approximately 5, 26%, then for this rate — as much as 7, 89%. The conclusion is simple — no matter how seductive the payment of 6 to 1 may seem, on the first five numbers you cannot put in any case. The best option for betting from a mathematical point of view is standard rates for equal chances with a payment of 1 to 1 and a probability of winning 47. 37%.
