In roulette, the best odds are generally associated with the even money bets, such as red or black, odd or even, and high or low. These bets have the highest probability of winning, at nearly 50%, and offer a 1:1 payout.

Some bets in American Roulette have an even higher house edge than the 5.26% average. For example, a bet on the Five Numbers (0, 00, 1, 2, 3) carries a house edge of 7.89%. 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).
