## Why does the Roulette a zero or double zero?

The zero ensures the casino house statistically has the edge. If there were only red and black, the probability would be compensated by 50 %. By having one zero in the French version the house edge is at 1.35 % (100 % / 37 fields / 2 ( since one zero only 50 % of the feed loses -but always look at each casinos rules individually to ensure which rules you are playing under because there are many exceptions! ) ). The American style with the "double zero" secures the casino a house edge of 5.26 % (100 % / 38 fields * 2 (There are two zeros in the field ) ). In addition, the player loses his full use of the zero - case.

Important for you to know now is: your chance of winning at roulette by zero is never exactly 50 % (regardless of whether they bet on red or black) but only 48.65% (French). Maybe it is the better preference to play the French version since your chance of winning is higher but it is the player's choice.

## What is the probability to zero in roulette?

According to the above- with read numbers, the probability is on the zero at standard French roulette at 2.7 % (100 % / 37 fields) or 1:37 and with the American variant at 5.26 % (100 % / 38 fields * 2 ( There are two zeros in the field ) ) or 1:19. However, they must have either zero or double zero in the direct bet. Then the probability is 2.63 % (100% / 38 fields * 1). Important for you to know, however, is the fact that roulette is a game of chance. Theoretically, it is possible that the null 100 times in a row played out. However, the probability of such a situation is very low.
