European Roulette

Roulette

The most widely played roulette variant globally, featuring a wheel with 37 numbered pockets: 1 through 36 (alternating red and black) and a single green zero (0). The house edge on all bets is 2.70%, exactly half that of American roulette. The number sequence on the European wheel is standardized and differs significantly from the American wheel arrangement. European roulette is the standard offering in virtually all casinos outside the United States and is the only version typically found in Macau, Singapore, Australia, and other Asia-Pacific jurisdictions. The betting layout includes the racetrack section for called bets in premium establishments.

In practice

In Macau, European roulette is the standard and is often referred to simply as “roulette” by casino staff. The 2.70% house edge is considered the baseline for comparison with other table games.
