The US version of the wheel is different from the European wheel in terms of the design. The wheel of the former is colored in red and black and has a visible difference between the even and the odd digits. In addition, it also has a double digit zero along with the traditional numbers, taking the total to thirty eight digits.

Even though the European wheel was the first to be devised and played with, the American version has become more popular due to its practical disposition. The wheel has equal positions and gives different players equal edge while playing a game. In addition, the European version is also a little biased towards the person playing even bets as he is the one who gets to play or exercise the prison rule. The person with the odd bet loses all his money to the house.
