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.
Outside bets in roulette carry the lowest risk. They cover more numbers yet the payouts are lower (1/1 for Red, Black, Odd, Even, 1 18, 19 36). These outside bets carry the best prospects for long-term wins.
