Up until that time there was only one zero on the roulette wheel, and this kind of wheel is know as the European roulette wheel, while the double zero wheel is known as the American roulette wheel.

When playing roulette it is important to remember a few simple things that will make your game play a lot more pleasant. Firstly, it is important that you remember to exchange you normal casino chips for roulette chips when you come to the table, since you cannot play roulette with normal casino chips. You can change these chips back later when you leave the game. Secondly, it is important that you remember to place your bets before the beginning of the game. Once the deals announces that no more bets are to be placed beyond that point, then you cannot place any more bets until the next round. It is a federal offense to do so!
