Why Is Single Zero Roulette Better than Double Zero? The payouts for all the bets are the same, but the house edge and the odds change dramatically. A single zero roulette wheel, though, only has a single green zero along with the numbers 1 through 16. The numbers between 1 and 36 are red and black (half each), and the wheel also has a 0 and a 00, both of which are colored green. A standard American roulette wheel has 38 colored, numbered pockets.
