If you have ever wondered why two roulette tables can look almost identical yet play so differently over time, the answer is simple: the wheel design changes the math. In the classic debate of European roulette vs American roulette, the key difference is single zero vs double zero. That one extra pocket (the 00) is the main reason American roulette typically costs players more in the long run.
The great news is that once you know what to look for, you can make smarter choices fast. By choosing the right roulette variant (and the right rules), you can improve your expected value, stretch your bankroll, and enjoy a smoother ride with your preferred betting style. For more info.
The core difference: wheel pockets and why they matter
Both European and American roulette use numbers 1 through 36. The difference is in the green pockets:
- European roulette has 37 pockets: numbers 1–36 plus a single 0.
- American roulette has 38 pockets: numbers 1–36 plus 0 and 00.
That extra 00 does not change the headline payout on most bets, but it does change your probability of winning. This is why players often prefer single-zero games when they have a choice.
Roulette odds and the roulette house edge (with real numbers)
Roulette payouts are designed so the casino advantage comes from the green pocket(s). A quick way to see it is to look at a straight-up bet (betting on a single number). In both games, the nominal payout is typically 35:1 (meaning you win 35 units of profit if your number hits).
But your chance to hit is different:
- European straight-up win probability: 1 / 37
- American straight-up win probability: 1 / 38
Because the payout does not increase to compensate for the extra pocket, the roulette house edge increases.
House edge comparison: European vs American roulette
| Variant | Pockets | Green pockets | Typical straight-up payout | House edge |
|---|---|---|---|---|
| European roulette | 37 | 0 | 35:1 | About 2.70% |
| American roulette | 38 | 0, 00 | 35:1 | About 5.26% |
Those percentages come directly from the wheel:
- European house edge: 1 / 37 ≈ 2.70%
- American house edge: 2 / 38 ≈ 5.26%
In practical terms, American roulette’s edge is nearly double. Over many spins, that difference can be the deciding factor between a session that lasts and one that burns through your budget faster than expected.
French roulette: European wheel, potentially better rules
French roulette typically uses the same single-zero wheel as European roulette (37 pockets). What makes it especially appealing is that many French tables include special roulette rules that can reduce the disadvantage on even-money bets (like red/black, odd/even, and high/low).
The two famous rules are La Partage and En Prison.
La Partage roulette rule (how it helps)
With La Partage, if you place an even-money bet and the ball lands on 0, you get half of your bet back (instead of losing the full amount).
This effectively cuts the house edge on even-money bets in half:
- European even-money bet (standard rules): about 2.70%
- French roulette with La Partage on even-money bets: about 1.35%
If you enjoy outside bets, La Partage can be one of the most player-friendly options commonly available in traditional roulette formats.
En Prison roulette rule (what it means)
With En Prison (French for “in prison”), if you place an even-money bet and 0 hits, your bet is not lost immediately. Instead, it is “held” for the next spin:
- If your even-money bet wins on the next spin, you get your stake back (typically without profit).
- If it loses on the next spin, you lose your stake.
On many tables, the overall effect on even-money bets is similar to La Partage in terms of reducing long-term disadvantage, while also giving you a second chance when zero appears.
Why single-zero wheels favor bankroll longevity (especially with outside bets)
Many players love roulette because it is simple and social, and because you can tailor your risk level. This is where single zero vs double zero becomes more than trivia: it can shape how long you can comfortably play with a given bankroll.
Outside bets feel steadier, but the wheel still matters
Outside bets (such as red/black) win more often than inside bets, so they can feel smoother. But the green pockets still create the casino edge, and in American roulette there are two of them. That means:
- More spins where your outside bet loses due to 0 or 00.
- A bigger long-term drain even if your win rate feels “close to 50/50.”
If you like the rhythm of outside betting, choosing European roulette (or French roulette with La Partage or En Prison) can be a straightforward upgrade because it keeps more of your money in play over time.
European roulette vs American roulette: what changes in strategy?
Roulette strategy cannot change the underlying odds, but it can change your volatility (how swingy your results are) and how efficiently you use your bankroll. The variant you choose influences what “good strategy” looks like in practice.
1) Prioritize the best rules first (the biggest lever you control)
- If you can choose, prioritize French roulette with La Partage or En Prison for even-money bets.
- If French rules are not available, choose European roulette (single zero) over American roulette whenever possible.
This is the most impactful decision because it directly improves your expected results without requiring any complicated betting pattern.
2) Match bet types to your goals
Different bets create different session experiences:
- Even-money bets (red/black, odd/even, high/low) can support longer sessions, especially on single-zero wheels.
- Dozens and columns offer a middle ground between frequent wins and bigger payouts.
- Inside bets (straight-up, splits, streets) create more dramatic swings and are best approached with a smaller portion of your bankroll per spin.
On a double-zero wheel, higher house edge means aggressive or high-volatility betting can deplete funds faster, so many players find a single-zero game more forgiving for longer play.
3) Keep staking simple to stay in control
A practical approach for many players is flat betting (betting the same amount per spin) or using small, pre-planned adjustments. This supports consistent bankroll management and makes it easier to stop at a chosen win goal or loss limit.

Availability: where you’re most likely to find each roulette variant
Variant availability can depend on region and venue type:
- European roulette and French roulette are common in many European casinos.
- American roulette is widely found in the United States and is common in many US-style casino floors.
- In online casinos, it is often possible to choose between multiple variants, so it can be easier to find single-zero tables and sometimes French rules.
If you have the option to select a table, taking a moment to confirm whether it is single zero vs double zero can be one of the highest-impact choices you make all session.
Frequently asked questions about European roulette vs American roulette
Is European roulette always better than American roulette?
From a math perspective, European roulette generally offers better roulette odds because its roulette house edge is lower (about 2.70% vs about 5.26%). “Better” for you also depends on what you enjoy, but single-zero wheels are widely considered more player-friendly.
Does the 35:1 payout change between European and American roulette?
In standard versions of both games, the straight-up payout is typically 35:1. The difference is not the payout but the number of pockets on the wheel, which changes the probabilities.
What are La Partage and En Prison in French roulette?
They are roulette rules that apply to even-money bets when 0 appears.La Partage returns half your stake immediately; En Prison holds the bet for the next spin, giving you a chance to recover it. Both can reduce player disadvantage on those bets versus standard European rules.
Do betting systems overcome the house edge?
No betting system changes the built-in roulette house edge created by the green pockets. What you can control is game selection (single zero vs double zero), the rules (French options), your bet sizing, and your session limits.
Takeaway: the best roulette choice for value-minded players
If your goal is to get more entertainment per dollar and improve your long-run position, the hierarchy is clear:
- Look for French roulette with La Partage or En Prison when you like even-money bets.
- If not available, choose European roulette (single zero).
- Play American roulette (double zero) when it is the only option, while recognizing the higher house edge.
In the end, the most practical “strategy” is simply selecting the most favorable table. Choosing single-zero wheels and player-friendly rules is a positive, confidence-building way to improve your roulette experience without changing how you like to play.
