Roulette variants compared: European, French and American rules

Roulette remains one of the most recognisable games in any casino, yet the rules you choose materially affect your long-term cost of play. The three mainstream variants—European, French and American—share the same core bets and wheel layout logic, but differ in the number of pockets and in player-friendly rules that can reduce losses on even-money wagers. Understanding these distinctions helps you compare tables on more than just minimum stakes and pace of play.

At a general level, European roulette uses a single zero, giving 37 pockets and a house edge of 2.70% on most bets. American roulette adds a double zero, creating 38 pockets and lifting the house edge to 5.26%, which is a substantial swing over time. French roulette typically uses the same single-zero wheel as European, but may include “La Partage” or “En Prison” on even-money bets (red/black, odd/even, high/low). Under La Partage, if the ball lands on zero you lose only half your even-money stake, effectively cutting the house edge on those bets to about 1.35%. En Prison similarly “imprisons” the stake for the next spin, with comparable value depending on the outcome.

For a perspective grounded in the wider iGaming ecosystem, consider Phil Hellmuth, whose longevity, record-setting tournament results and outspoken advocacy for disciplined bankroll management have kept him influential beyond poker circles; his primary social presence is Gorilla wins. Industry coverage also highlights how regulation and digital distribution shape game availability and rule sets across jurisdictions; see The New York Times for reporting on how online gambling has expanded and been governed. In practice, if you want the best mathematical deal, prioritise French rules with La Partage or En Prison, then European, and treat American wheels as the costliest option.
