If you’ve ever walked through a casino (or browsed play blackjack), you’ve probably seen both European roulette and American roulette. At first glance, they look nearly identical: the same spinning wheel, the same layout, and the same iconic bets like red or black, dozens, columns, and straight-up numbers.
But one small detail changes everything: the number of zero pockets on the wheel. That single design choice shifts the odds, the house edge, and your long-term expected return. And if you care about getting more play for your bankroll, it’s a difference worth knowing.
The core difference: wheel configuration (single-zero vs double-zero)
European and American roulette use the same general concept (a ball lands in a numbered pocket), but the wheels differ in how many pockets they have.
- European roulette wheel: 37 pockets (numbers 1 to 36 plus a single 0).
- American roulette wheel: 38 pockets (numbers 1 to 36 plus 0 and 00).
That extra 00 pocket is the entire reason American roulette typically costs more to play in the long run.
European vs American roulette odds (straight-up, even-money, and more)
Most roulette payouts are the same across both variants. For example, a straight-up bet on a single number generally pays 35 to 1 whether you’re playing European or American roulette.
What changes is the probability of winning, because the number of total pockets changes.
Straight-up bet probability
- European roulette: 1 winning pocket out of 37 total =1/37 (about 2.70%).
- American roulette: 1 winning pocket out of 38 total =1/38 (about 2.63%).
That looks like a small difference in win probability, but across repeated play it meaningfully impacts expected losses, which is why roulette players often prioritize single-zero tables.
Even-money bet probability (red/black, odd/even, high/low)
Even-money bets pay 1 to 1 in both versions, but the zeros work against you:
- European roulette: 18 winning outcomes, 18 losing outcomes, plus 1 zero that causes a loss (in standard rules).
- American roulette: 18 winning outcomes, 18 losing outcomes, plus 2 zero pockets (0 and 00) that cause a loss (in standard rules).
House edge: the number that matters most
When people say one roulette version is “better,” they usually mean it has a lower house edge (also called the casino advantage). This is the long-run average percentage the casino expects to keep from total bets.
Here are the widely cited standard house edges for typical rules:
- European roulette (single-zero): about 2.70%.
- American roulette (double-zero): about 5.26%.
In plain terms, American roulette’s house edge is roughly about double European roulette’s, mainly because of the extra 00 pocket.
Expected return (RTP) in simple terms
Another helpful way to look at value is return to player (RTP), which is simply 100% - house edge.
- European roulette RTP: about 97.30%.
- American roulette RTP: about 94.74%.
This doesn’t mean you “get back” that percentage every session. Variance can be huge in roulette. But over many spins, a lower house edge generally means more staying power for the same bankroll and the same style of betting.
Quick comparison table: European vs American roulette
| Feature | European Roulette | American Roulette |
|---|---|---|
| Wheel pockets | 37 (1–36 plus 0) | 38 (1–36 plus 0 and 00) |
| Straight-up win chance | 1/37 (about 2.70%) | 1/38 (about 2.63%) |
| Typical house edge | About 2.70% | About 5.26% |
| RTP (approx.) | 97.30% | 94.74% |
| Payouts and bet types | Same as American in standard rules | Same as European in standard rules |
| Common locations | More common in Europe and many online casinos | More common in the United States |
Why the payouts look the same (and why that benefits the casino)
Roulette payouts are designed around a 36-number framework (the 1–36 set), but the wheel includes one or two extra pockets (the zeros) that do not improve player payouts.
For example:
- A straight-up bet pays 35 to 1, but the true “fair” payout would need to be 36 to 1 on a 37-pocket wheel, and 37 to 1 on a 38-pocket wheel (if there were no house edge).
- Even-money bets pay 1 to 1, but the zeros create extra losing outcomes without increasing payouts.
This is why the number of zero pockets is such a powerful lever. You’re playing the same bets for the same payouts, but with worse probabilities when an extra pocket is added.
European rule variations that can boost value: La Partage and En Prison
Beyond the single-zero wheel, European roulette sometimes includes additional rules that can make even-money bets (red/black, odd/even, high/low) more player-friendly when the ball lands on zero.
La Partage
With La Partage, if you place an even-money bet and the result is zero, you typically get half your stake back rather than losing it all.
Practical impact: this can reduce the effective house edge on even-money bets to approximately 1.35% (about half of the standard European edge on those bets), because the “zero event” becomes less costly.
En Prison
With En Prison, if you place an even-money bet and zero hits, your bet is “imprisoned” (held) for the next spin rather than immediately losing. If your bet wins on the next spin, you generally get your stake back (not extra profit). If it loses, you lose the stake.
Practical impact: like La Partage, En Prison can improve the expected return on even-money bets compared to standard rules, especially for players focused on red/black style play.
Important note on scope
These rules typically apply to even-money bets only. They do not usually change the math for straight-up bets, splits, streets, corners, dozens, or columns in the same way.
Are the betting options the same?
In standard casino roulette, the betting options and payouts are generally identical between European and American tables. You’ll usually find the same categories:
- Inside bets: straight-up, split, street, corner, six line.
- Outside bets: red/black, odd/even, high/low, dozens, columns.
The key difference isn’t what you can bet on. It’s how many pockets can beat you while paying the same prizes.
Availability: where you’re most likely to find each version
In many venues, roulette availability follows geography and tradition:
- American roulette (0 and 00) is commonly found in the United States, particularly in traditional brick-and-mortar casinos where the double-zero wheel has long been standard.
- European roulette (single zero) is more common in Europe and is also widely offered in many online and live dealer lobbies because it’s attractive to value-conscious players.
That said, many casinos and platforms now offer both. The best approach is to check the table information before you buy in.
How to choose the better roulette table in under 30 seconds
If your goal is better value and a lower long-term cost to play, here’s a quick, practical checklist.
1) Look at the wheel: is there a 00?
- If you see 00, it’s American roulette (double-zero) and typically carries the higher house edge.
- If you see only 0, it’s European roulette (single-zero) and typically offers better odds.
2) Check the rules panel for La Partage or En Prison
If you enjoy even-money bets, European tables with La Partage or En Prison can be a strong value upgrade. If those rules are available, they are usually listed in the table rules.
3) Match the variant to your betting style
- If you mostly play even-money bets: prioritize single-zero, and look for La Partage or En Prison when possible.
- If you mostly play straight-up numbers: single-zero still improves your probability, but special zero rules usually won’t apply to your bet type.
4) Don’t confuse “more excitement” with “better value”
American roulette can feel fast and familiar (especially in US casinos), but when you compare the numbers, European roulette typically delivers more spins per bankroll over time because of the lower house edge.
Real-world benefits of choosing European roulette
Picking European roulette isn’t about chasing a secret trick. It’s about making a smart, math-backed choice that can improve your overall experience.
- More value per bet: A lower house edge means the game takes less from action over time.
- Longer sessions for the same bankroll: Many players find they can enjoy more spins at comparable stakes.
- Better conditions for simple strategies: If you like straightforward even-money play, La Partage or En Prison can make those bets more resilient when zero appears.
- Easy to verify: You don’t have to “trust” marketing; you can literally see whether the wheel has 0 only or 0 and 00.
Plenty of experienced players treat single-zero roulette as a baseline standard: if both are available at similar limits, they’ll choose the version with the lower house edge because it’s a clear, measurable advantage in value.
European vs American roulette: the best-value conclusion
If you’re choosing between the two and all else is equal, European roulette is typically the better-value game because it has a single zero (37 pockets), a straight-up win probability of 1/37, and a house edge of about 2.70%.
American roulette adds the 00, expanding the wheel to 38 pockets, lowering straight-up odds to 1/38, and increasing the house edge to roughly 5.26%.
And if you can find European roulette with La Partage or En Prison, even-money bets can become especially attractive by reducing the sting of zero results. In other words: the smartest roulette choice usually comes down to one simple rule.
When you have the option, choose single-zero roulette for better odds and better long-term value.
Quick FAQs
Is European roulette “easier to win” than American roulette?
European roulette offers slightly better probabilities on the same bets because there is one fewer pocket. Over time, that translates into a lower house edge, which is why it’s widely considered better value.
Do European and American roulette pay the same?
Yes, standard payouts and betting options are generally the same. The difference is the number of pockets on the wheel, which changes the odds.
Does La Partage or En Prison apply to all bets?
Typically, no. These rules are usually limited to even-money bets and are designed to soften losses when zero appears.
Which roulette variant is more common in the US?
American roulette (double-zero) is traditionally more common in many US casinos, while European roulette is more common across Europe and widely available online.
Practical takeaway: If you want a roulette game that’s more bankroll-friendly without changing how you play, start by choosing a single-zero European wheel, and then look for La Partage or En Prison if you prefer even-money bets.
