Two Wheels, Very Different Odds
Roulette is one of the most iconic casino games in the world, but not all roulette wheels are created equal. The two most common versions — European and American roulette — look similar on the surface but have one critical difference that significantly impacts your odds as a player.
The Core Difference: The Double Zero
The fundamental distinction between the two versions comes down to the wheel layout:
- European Roulette: 37 pockets — numbers 1–36 plus a single zero (0)
- American Roulette: 38 pockets — numbers 1–36 plus a single zero (0) and a double zero (00)
That extra "00" pocket on the American wheel might seem minor, but it has a major effect on the house edge.
House Edge Comparison
| Variant | Number of Pockets | House Edge |
|---|---|---|
| European Roulette | 37 | ~2.7% |
| American Roulette | 38 | ~5.26% |
| French Roulette (La Partage) | 37 | ~1.35% on even bets |
The American wheel's house edge is nearly double that of the European version. Over many rounds, this difference is statistically significant for the player.
Betting Options: Are They the Same?
Both versions offer the same core betting options — inside bets (straight-up, split, street, corner) and outside bets (red/black, odd/even, high/low, dozens, columns). However, American roulette adds one additional bet:
- Five-Number Bet (Basket Bet): Covers 0, 00, 1, 2, and 3. This bet carries the highest house edge on the American table (~7.89%) and is generally considered one of the worst bets in roulette.
French Roulette: The Third Option
If you're looking for the best odds, French Roulette deserves a mention. It uses the same single-zero wheel as European roulette but adds two special rules:
- La Partage: If the ball lands on zero, you get half your even-money bet back.
- En Prison: Your even-money bet is "imprisoned" on a zero result and gets another chance on the next spin.
These rules effectively cut the house edge on even-money bets to around 1.35%, making French Roulette the most player-friendly variant available.
Which Version Should You Play?
From a pure mathematical standpoint, the answer is straightforward:
- French Roulette (if available) — best odds for even-money bets
- European Roulette — solid choice with a reasonable house edge
- American Roulette — avoid if you have the choice; the double zero significantly works against you
In online casinos, all three versions are typically available. There's rarely a reason to choose American over European roulette unless you specifically enjoy the extra betting option or prefer the layout aesthetically.
Tips for Roulette Players
- Stick to outside bets (red/black, odd/even) for the longest playtime — they have the best probability of winning each spin.
- Understand that no betting system (Martingale, Fibonacci, etc.) changes the fundamental house edge.
- Set a session budget and bet size before you start spinning.
- Play European or French roulette whenever the option exists.
