The pockets of the roulette wheel are numbered from 0 to 36. In number ranges from 1 to 10 and 19 to 28, odd numbers are red and even are black. In ranges from 11 to 18 and 29 to 36, odd numbers are black and even are red. There is a green pocket numbered 0 (zero).
The payoff numbers are either black, red or green. The numbers one through 36 are either red or black. The number (s) 0 and/or 00 are green. The best bet for the player is to play on a roulette wheel where there is a single zero and not a double zero.
