A roulette variant with one green zero is more spread in European casinos and in some gambling houses of Nevada and Atlantic City in the United States. Thus, American casinos tend to experiment with European-style wheels to attract more players.

But why making a choice in favor of European Roulette is a more reasonable solution in terms of potential profit? The wheel with one zero features one green cell and a total of 37 positions compared to 38 positions in the wheel with more than one zero. The absence of a second cell with zero reduces the house edge to 2.7%. Based on the theory of probability, the player will lose one bet each 37 plays; and 1/37 equals 2.7%. When playing roulette with two zeros players are likely to lose two bets each 38 plays, which is 5.26%.

European Roulette is a non-proliferation phenomenon in the gaming industry. Infrequently, casinos are offering players trying their luck at roulette with one zero, which is the only difference of European roulette from an American analog.

Some casinos offer American roulette making the emphasis on some benefits it provides. Therefore, if you play the wheel with two zeros and the ball misses the green cell (zero), the casino takes only half of each bet and makes the payment of 1 to 1. Such action on the part of the casino is called surrender. This decreases the advantage of a gambling house to 2.63%.

An opportunity to give up when playing with one zero significantly reduces the house edge – to a level of 1.35%, which means a loss of half rate of 37 attempts. This balance of power certainly attracts more gamblers.

However, nowadays finding a roulette with one zero with an extra advantage provided by a casino to the players is a tough mission. However, you may want to check the options of online casino DGFEV, the aggregator of casinos with user rating above average.

## The tough reality

As a rule, the winning rate for split is calculated according to $17 to $1 rate, while in fact it should be 18 dollars. Basing on the fact that the sum of the two numbers in the correct ratio of chances equals the number of all the possibilities, it is possible to calculate the amount for bet split. Thus, it will be 19 (18 + 1). In order to calculate the house edge, you need to share the amount of money lost by players by the total number of probabilities.

Deposit wheel with two zeros gives players 2.63% on payments of 1: 1. How do they get this number? It is known that the probability equals 38. 18 cells give the winning for one element and 18 cells for another one. Another two numbers (both green) give half loss elements of each. Thus, for the 38 attempts the player loses one element (1/2 + 1/2): as a result, we get 1/38 which is 2.63% in percent ratio.
