Why the Variant You Choose Matters
Roulette is one of the most recognised casino games in the world, but not all roulette tables are created equal. The variant you play directly affects the house edge — the mathematical advantage the casino holds over players — and certain special rules can significantly improve your odds. Understanding the differences between European, American, and French Roulette is one of the most impactful decisions a roulette player can make.

European Roulette
European Roulette is the most widely played variant online. Its wheel features 37 pockets — numbers 1 through 36 plus a single zero (0). The house edge of 2.70% applies uniformly to all bet types. It offers a clean, balanced experience and is available at virtually every online casino. For most players, this is the go-to choice.
Best bets: Outside bets (red/black, odd/even, high/low) for lower risk; straight-up number bets for higher payouts.
American Roulette
American Roulette adds a second green pocket — the double zero (00) — bringing the total to 38 pockets. This single addition nearly doubles the house edge to 5.26%. The Five Number Bet (0, 00, 1, 2, 3) carries an even worse house edge of 7.89% and should always be avoided.
Verdict: Unless the specific game offers unique features that offset this, American Roulette is generally the weakest choice for players seeking value.
French Roulette
French Roulette uses the same 37-pocket wheel as European Roulette but adds two player-friendly rules:
- La Partage: If the ball lands on zero, players who placed even-money bets (red/black, etc.) receive half their stake back, effectively halving the house edge on those bets to 1.35%.
- En Prison: Instead of receiving half back, the bet is "imprisoned" for the next spin. If it wins, the full stake is returned. This carries the same mathematical value as La Partage.
For players who favour even-money bets, French Roulette offers the best house edge of any standard roulette variant.
Which Variant Should You Choose?
- If you bet primarily on even-money outcomes: French Roulette is the best choice.
- If you prefer number bets or a mix of bet types: European Roulette is a solid, widely available option.
- Avoid American Roulette unless it's the only option available, as the double zero significantly increases the house edge without adding player value.
Live vs. Digital Roulette
Both live dealer and RNG (random number generator) versions of these variants are available online. Live roulette adds an authentic atmosphere and transparency, while RNG roulette allows faster play and often lower minimum bet limits. The rules and house edges are identical — the choice comes down to personal preference.
Understanding roulette variants is a straightforward way to make more informed decisions before you place a single chip. Always check which variant a table uses before playing.
