American roulette is different
The rules and chances of winning at American roulette differ from those of French roulette only in that the stakes of even-money bets are always halved if zero comes up. Bets are made with special chips, so-called wheel-checks, that come in seven different colours and are only available at the table. Each player plays with his/her own colour and determines its value when this is purchased. The game is faster than is the case with French roulette, because the number of players on an American table is limited to seven.
