If you’re comparing European roulette vs American roulette, you’re already doing something smart: you’re focusing on the single biggest factor that shapes your long-term results in roulette—house edge. The headline is simple and player-friendly:
- European roulette uses a single-zero wheel with 37 pockets and a typical house edge of about 2.70%.
- American roulette uses a double-zero wheel with 38 pockets and a higher house edge of about 5.26%.
The payout structure (including the classic 35:1 straight-up payout) and most bet types are the same. The difference is that the American wheel adds an extra pocket (00)—and that extra pocket meaningfully increases the casino advantage.
Practical recommendation: When you have a choice, prefer single-zero (European or French) roulette—both in land-based casinos and online—because the lower house edge helps your bankroll last longer.
Quick Comparison: European vs American vs French Roulette
Here’s the fastest way to see how these roulette variants stack up where it matters most.
| Variant | Pockets | Zeros | Typical house edge | Notable rules |
|---|---|---|---|---|
| European roulette | 37 | 0 | ~ 2.70% | Standard European layout |
| American roulette | 38 | 0, 00 | ~ 5.26% | Extra 00 pocket increases edge |
| French roulette | 37 | 0 | ~ 2.70% (can be lower on even-money bets) | La partage or en prison may apply |
The Core Difference: Wheel Layout and Pocket Count
European roulette: 37 pockets (single-zero)
A European roulette wheel contains:
- Numbers 1 through 36
- A single green 0
That makes 37 pockets in total.
American roulette: 38 pockets (double-zero)
An American roulette wheel contains:
- Numbers 1 through 36
- A green 0
- An additional green 00
That makes 38 pockets in total. This one extra pocket is the main reason American roulette is less favorable for players over time.
Roulette House Edge Explained (with Exact Percentages)
The house edge is the built-in advantage the casino has on each bet over the long run. In roulette, it’s driven primarily by how many zero pockets exist compared to how payouts are calculated.
Why European roulette is ~ 2.70%
European roulette has 37 equally likely outcomes. For many common bets, payouts are structured as if there were only 36 outcomes (the 1–36 numbers), and the extra 0 creates the casino advantage.
The standard European house edge is:
1 / 37 ≈ 2.70%
Why American roulette is ~ 5.26%
American roulette has 38 equally likely outcomes due to the extra 00 pocket. That increases the mismatch between payouts and true odds.
The standard American house edge is:
2 / 38 ≈ 5.26%
What that means in real play
Even though roulette outcomes are random, the house edge influences your expected cost of playing over time. With a lower edge, you typically get:
- More play time for the same bankroll
- Smoother bankroll swings over long sessions (because you’re losing less in expectation per unit wagered)
- Better value from promotions or comps (because your expected loss per spin is lower)
Are the Payouts Different? Mostly No (That’s the Trick)
A key reason the 00 matters is that the payouts generally don’t improve to compensate for the extra pocket. For example:
- Straight-up (single number) typically pays 35:1 in both European and American roulette.
- Red/Black, Odd/Even, and High/Low typically pay 1:1 in both.
- Common inside and outside bets (splits, streets, corners, dozens, columns) are broadly the same.
So while the game looks and feels similar across versions, the American wheel’s extra 00 pocket quietly raises the casino advantage on nearly every standard bet.
French Roulette: The Player-Friendly European Variant
French roulette is usually played on a single-zero wheel like European roulette, but it often features extra rules that can improve outcomes on even-money bets (like red/black, odd/even, high/low).
La partage (often best for even-money bettors)
Under la partage, if the ball lands on 0 and you made an even-money bet, you typically lose only half your stake (instead of the full amount).
This effectively cuts the house edge on even-money bets in half:
- From ~2.70%
- Down to ~1.35% on eligible even-money bets
En prison (similar benefit, with a twist)
Under en prison, if the ball lands on 0 and you made an even-money bet, your bet is “imprisoned” for the next spin rather than lost immediately. Rules vary, but a common approach is:
- If your even-money bet wins on the next spin, you get your stake back (often without profit).
- If it loses, you lose the stake.
In many implementations, en prison also results in an effective house edge of about 1.35% on even-money bets (though details can differ by casino).
If your style of play leans heavily on outside even-money bets, French roulette with la partage or en prison can be a meaningful upgrade in value.
Wheel Order Differences: Same Numbers, Different Arrangement
Another real (but often overlooked) difference in European roulette vs American roulette is the wheel order—the sequence of numbers around the wheel. Both wheels include numbers 1–36, but the arrangement differs between the two formats, and American wheels also include 00.
What’s the benefit of understanding this?
- It helps you quickly identify what game you’re looking at in a casino.
- It reinforces that the key advantage comes from zero count, not from a different set of bet options.
- It helps avoid confusion between table layout and wheel type (especially in busy live environments).
Important note: regardless of wheel order, in properly run roulette each pocket is designed to be equally likely over the long run, so the house edge difference is still driven mainly by single-zero vs double-zero.
Which Roulette Variant Should You Choose?
Choose European roulette when you want better value per spin
If your priority is maximizing your chances over time (and getting more entertainment from your bankroll), European roulette is the clear pick over American roulette due to its lower house edge of about 2.70%.
Choose French roulette when you can get la partage or en prison
If you see French roulette with la partage or en prison, that’s often even better—especially if you mostly place even-money bets. The effective edge can drop to about 1.35% on those bets, which is a standout advantage in a classic casino game.
Choose American roulette only when there’s no alternative
American roulette can still be fun and familiar, but the math is simply less favorable because the house edge is about 5.26%. If you have the option to play single-zero instead, that’s usually the smarter and more bankroll-friendly choice.
Practical Tips to Spot (and Select) the Best Roulette Table
Whether you’re playing in a land-based casino, online, or looking at black jack online, a few quick checks can help you consistently land on the most player-friendly version available.
1) Look for the zero count first
- One green pocket (0)= usually European or French roulette.
- Two green pockets (0 and 00)= American roulette.
2) Check for French rules on even-money bets
If you’re betting red/black, odd/even, or high/low, look for wording like la partage or en prison. These rules can improve the value of those specific bets.
3) Keep expectations realistic and focus on the advantage you can control
Roulette remains a game of chance. You can’t predict the next number reliably, but you can choose the game with the lower house edge. That choice alone can noticeably improve your overall experience by:
- Reducing expected losses over time
- Helping your bankroll last longer
- Making each session feel more sustainable and enjoyable
European vs American Roulette: Common Bets (Same Names, Different Value)
Most roulette bets are identical across European and American games, but their value differs because the probability differs. Here’s a quick overview of popular bets and what stays consistent.
| Bet type | Typical payout | Available in European? | Available in American? | Why the wheel matters |
|---|---|---|---|---|
| Straight-up (1 number) | 35:1 | Yes | Yes | Same payout, but the extra 00 worsens odds in American |
| Red / Black | 1:1 | Yes | Yes | American has two zero pockets that cause more losses on even-money bets |
| Dozens / Columns | 2:1 | Yes | Yes | Same payout, different probability due to 37 vs 38 pockets |
| Splits / Streets / Corners | Varies | Yes | Yes | Same structure, but European is still more favorable overall |
FAQ: Single-Zero vs Double-Zero Roulette
Is European roulette always better than American roulette?
From a house-edge perspective, yes: European roulette’s typical house edge is about 2.70% versus about 5.26% for American roulette. Lower edge generally means better value over time.
Do European and American roulette have the same payouts?
In most cases, yes—especially the headline payout of 35:1 for a straight-up bet. The key difference is that American roulette adds 00 without improving payouts, increasing the casino advantage.
What is the best roulette for even-money bets?
Often it’s French roulette with la partage or en prison, because those rules can reduce the effective house edge on even-money bets to about 1.35%.
Does wheel order change the odds?
Wheel order differs between European and American roulette, but the main driver of odds and house edge is the number of zero pockets. A single-zero wheel is typically the better pick.
Bottom Line: The Best Wheel to Choose for Better Value
If you remember just one thing from the European roulette vs American roulette comparison, make it this: the extra 00 in American roulette roughly doubles the house edge. Since payouts are usually the same, choosing a single-zero wheel is one of the cleanest, easiest upgrades you can make as a roulette player.
- Choose European roulette (single-zero, 37 pockets) for a typical house edge of about 2.70%.
- Choose French roulette when it includes la partage or en prison for even-money bets that can drop to about 1.35%.
- Avoid American roulette (double-zero, 38 pockets) when you have a choice, since the house edge is about 5.26%.
That one decision—single-zero over double-zero—can help your bankroll go further, keep your sessions more enjoyable, and give you the best version of roulette that casinos commonly offer.
