The American Roulette wheel uses 36 numbers, the same as its European cousin, but adds an extra option with a 'double zero'. The clockwise sequence of numbers changes to:
0-28-9-26-30-11-7-20-32-17-5-22-34-15-3-
24-36-13-1-00-27-10-25-29-12-8-19-31-18-
6-21-33-16-4-23-35-14-2
The extra 'double zero' option and the different sequence of numbers open up whole new bets for the player to make.
