Betting on green pays out either 35 to 1 or 17 to 1, depending on the roulette variation you're playing and your bet. In American roulette, the wheel features a green 0 and 00, while the European version just has the single green 0. If you bet on 0 or 00 on an American wheel, and your bet hits, you'll get a payout of 35 to 1. If you place a row bet (betting on both 0 and 00), and your bet hits, you'll get a payout of 17 to 1. As the European wheel only has the one green 0, you can only place a single bet, however it's the same 35 to 1 payout as the American version if your bet hits.
