Roulette variants compared: European, American and French roulette

Roulette remains a defining casino table game because tiny rule differences can materially change the odds. The three mainstream variants—European, American and French—share the same core mechanic: a spinning wheel, a ball, and bets on numbers or groups. What separates them is the wheel layout and a handful of table rules that influence the house edge, volatility, and the value of “even-money” bets such as red/black or odd/even.

European roulette uses a single zero (0) on a 37-number wheel, producing a house edge of about 2.70% on most bets. American roulette adds a double zero (00), expanding the wheel to 38 pockets and raising the house edge to roughly 5.26%, which is why many experienced players avoid it when alternatives exist. French roulette also uses a single-zero wheel, but often includes “La Partage” or “En Prison” on even-money bets: when the ball lands on zero, you may lose only half your stake or have it held for a subsequent spin. These rules can reduce the effective house edge on even-money wagers to around 1.35%, making French tables particularly attractive for conservative staking.
