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).
