【How-to】How does roulette work - Howto.org

In American roulette, the wheel features a green 0 and 00, while the European version just has the single green 0. If you chance on 0 or 00 on an American wheel, and your chance hits, you’ll get a payout of 35 to 1. If you place a “row” chance (betting on both 0 and 00), and your chance hits, you’ll get a payout of 17 to 1.
