Red/Black Bet
Definition
The most common even-money bet in roulette. Pays 1:1. Covers 18 numbers each. Probability of winning is 48.6% (European) or 47.4% (American) because zero/double-zero are neither red nor black.
Red/Black is the most well-known even-money bet in roulette. Eighteen numbers are colored red and eighteen are colored black, with zero (and double zero in American roulette) being green. The bet pays 1:1 and wins 48.6% of the time in European roulette (47.4% in American).
Despite being the simplest bet in roulette, Red/Black demonstrates the house edge clearly. With 18 winning numbers out of 37 (European), the odds are slightly against you every spin. This small imbalance, caused by the green zero, is enough to guarantee the casino profits over millions of spins.
Red/Black is an excellent bet when played at French roulette tables with la partage or en prison rules. Under these rules, landing on zero returns half your even-money bet, cutting the house edge from 2.7% to 1.35%. This makes the Red/Black bet one of the best wagers available in any casino.
