What are the odds in roulette? The roulette odds of winning a round depend on the number of outcomes covered in the bet. If you bet on only one number, you are facing 1-in-37 odds in European roulette and 1-in-38 odds for the American version. In both cases however, the roulette payout for straight bets is 35:1.

A player may bet on single numbers, rows of numbers, or on adjacent numbers. A player also may play colors, odd or even numbers, among others. A bet on a single number pays 35 to 1, including the 0 and 00. Bets on red or black, odd or even pay 1 for 1, or even money.

The Martingale Roulette Strategy\n\n This is the simplest and most popular betting system for casino games with even money payouts, but not really useful for casino games like slots. This means that you will have to stick to the outside bets, like odd/even, red/black, or low/high.
