Roulette looks simple on the surface: pick a number or a type of outcome, place your chips, and let the wheel decide. But one small detail can make a big difference to your long-term results: whether the wheel has a single zero or a double zero.
European roulette uses a single-zero wheel (0) with 37 pockets, while American roulette uses a double-zero wheel (0 and 00) with 38 pockets. The payouts for standard bets are mostly the same in both versions, so the extra pocket in American roulette is what increases the casino’s edge.
If your goal is to get more value out of every spin, understanding these formats helps you make smarter choices, spot better tables faster, and keep more of your bankroll in play for longer.
Quick comparison: European roulette vs American roulette
| Feature | European Roulette | American Roulette |
|---|---|---|
| Pockets on the wheel | 37 (numbers 1–36 plus 0) | 38 (numbers 1–36 plus 0 and 00) |
| Key visual difference | One green pocket: 0 | Two green pockets: 0 and 00 |
| House edge (standard rules) | About 2.70% | About 5.26% |
| Even-money bets (Red/Black, Odd/Even, High/Low) | Often eligible for rules like La Partage or En Prison (when offered) | Usually no La Partage or En Prison in standard casino offerings |
| Where you commonly see it | Common in Europe and widely available online | Common in U.S. land-based casinos |
The biggest difference: single zero vs double zero
The extra 00 pocket in American roulette does one thing extremely well for the house: it adds another outcome that is neither red nor black, neither odd nor even, and neither high nor low. Since the payouts for standard bets do not increase to compensate, the odds become less favorable for players.
In practical terms, the American wheel creates more “miss” outcomes for common bets, while the European wheel keeps the game closer to its classic, lower-edge structure.
House edge explained (without the math headache)
The house edge is the casino’s built-in advantage over time, assuming standard payouts. It does not mean you lose that percentage every session, but it is a reliable indicator of which version is more player-friendly across many spins.
European roulette house edge: about 2.70%
European roulette has 37 equally likely outcomes. Many popular bets pay as though there were only 36 outcomes (because 1–36 are the main number range), and the 0 is what creates the edge.
American roulette house edge: about 5.26%
American roulette has 38 equally likely outcomes. Adding 00 effectively doubles the advantage compared to the European wheel under standard rules, because there are now two green pockets working against the player on most bet types.
Do payouts change between European and American roulette?
In most standard casino roulette games, the payouts remain the same across both versions for the classic bets. That is why the number of pockets matters so much.
- Straight up (single number) typically pays 35 to 1
- Split (two numbers) typically pays 17 to 1
- Street (three numbers) typically pays 11 to 1
- Corner (four numbers) typically pays 8 to 1
- Line (six numbers) typically pays 5 to 1
- Dozens and columns typically pay 2 to 1
- Even-money bets (Red/Black, Odd/Even, High/Low) typically pay 1 to 1
Because these payouts do not improve when a second green pocket is added, the American wheel’s advantage rises.
How La Partage and En Prison can improve your results (on even-money bets)
Some European roulette tables offer special rules designed to soften the impact of the 0 on even-money bets like Red/Black, Odd/Even, and High/Low. When you find these rules, they can be a meaningful upgrade for value-focused play.
La Partage: you get half back when 0 hits
With La Partage, if you place an even-money bet and the ball lands on 0, you typically lose only half of your even-money stake (instead of losing it all). This reduces the effective house edge on those even-money bets to about 1.35%.
En Prison: your even-money bet is “imprisoned” for one spin
With En Prison, if an even-money bet loses because the ball lands on 0, your bet is not immediately lost. Instead, it is held for the next spin. If your bet wins on the next spin, you generally get your stake back (not an additional win). If it loses again, you lose the stake.
Like La Partage, this can also bring the effective house edge on even-money bets down to roughly 1.35% under typical conditions.
Why these rules matter
If you enjoy even-money betting for its steadier pace, finding a European table with La Partage or En Prison is one of the most practical ways to upgrade your odds without changing your style. It is a “rules win” that can compound over a long session.
Wheel layout differences: what you see (and what it changes)
European and American roulette wheels are arranged differently, and the American wheel includes the extra 00 pocket. While the precise order of numbers around the wheel is not the same between the two formats, the key takeaway for most players is simple: more green pockets means higher house edge.
For everyday decision-making at the table, you rarely need to memorize wheel sequences. The best “at-a-glance” check is the pocket count and whether you see 0 alone or 0 and 00 together.
Availability: where you’re most likely to find each version
Knowing where each roulette type is commonly offered helps you find your preferred game faster, especially when traveling or choosing between online lobbies.
European roulette is commonly found in Europe and online
Single-zero roulette is widely associated with European casinos, and it is also common across many online casino platforms. For players who prioritize lower house edge, this availability is a big advantage: you can often shop around for table limits and rules that suit your bankroll.
American roulette is common in U.S. land-based casinos
In many U.S. brick-and-mortar casinos, double-zero roulette is a standard offering. That does not mean you cannot find single-zero games in the U.S., but it is typically less common, so it pays to look closely at table signage and ask the dealer if multiple roulette variants are available.
Practical tips to get more value from roulette
Roulette is a negative-expectation game in the long run, but your choices can still influence how far your bankroll goes and how enjoyable your sessions feel. These tips focus on boosting value and reducing avoidable disadvantages.
1) Choose single-zero roulette whenever possible
If you have the option between European and American roulette, the single-zero wheel is typically the better value because the house edge is about 2.70% instead of about 5.26%. Over many spins, that difference can be substantial.
2) Look for La Partage or En Prison when betting even-money
If you like Red/Black, Odd/Even, or High/Low bets, a table offering La Partage or En Prison can lower the effective house edge on those bets to about 1.35%. That is one of the strongest rule-based advantages you can find in traditional roulette.
3) Always check the table rules before you play
Two tables labeled “European roulette” can still play differently based on rules and optional features. Before you buy in, take a moment to confirm:
- Whether it is single-zero or double-zero
- Whether La Partage or En Prison is offered (and on which bets)
- Minimum and maximum bets
- Any side bets or special wagers and how they pay
4) Compare table limits to match your bankroll
Finding the “right” table limit is a feel-good upgrade that many players overlook. A lower minimum can help you:
- Play more spins for the same budget
- Reduce short-term volatility
- Stick to a pre-planned session size without pressure
Higher-limit tables can be fun for bigger bankrolls, but they can also shorten sessions quickly if the variance runs cold.
5) Manage your bankroll like a pro (simple, effective habits)
Bankroll management is not about guaranteeing wins; it is about controlling the pace of play and protecting your entertainment budget.
- Set a session budget and treat it as a fixed cost for entertainment.
- Pick a bet size that lets you play a meaningful number of spins (many players aim for a bet size that is a small fraction of their session bankroll).
- Decide your stopping points in advance: a walk-away win target and a firm loss limit can prevent emotional decisions.
6) Be selective with side bets
Some roulette tables offer optional side bets designed for excitement and bigger payouts. They can add variety, but they often come with a higher house edge than classic bets. If your priority is value, focus most of your action on the standard bet types and treat side bets as an occasional add-on rather than the core strategy.
What doesn’t change: the core roulette experience
One reason roulette stays popular across both formats is that the game’s flow feels familiar either way. You still get:
- A wide menu of bets, from simple even-money choices to high-payout number bets
- Fast rounds and a social, watch-the-ball excitement
- Clear outcomes and straightforward rules compared with many other table games
This is good news: you can upgrade your odds (by choosing single-zero and favorable rules) without sacrificing the classic roulette experience.
Real-world “wins” players get from choosing the right roulette table
While no roulette choice can eliminate the house edge, picking smarter tables tends to produce tangible benefits players notice quickly.
- Longer playtime per bankroll: Choosing a lower-edge game can help your session last longer, especially when combined with a sensible bet size.
- More consistent pacing on even-money bets: Tables with La Partage or En Prison can reduce the sting of a zero on Red/Black-style betting, which many players find improves the overall rhythm of play.
- Better confidence in your decisions: When you know exactly why you picked a table (single zero, favorable rules, comfortable limits), you spend less time second-guessing and more time enjoying the game.
FAQ: European vs American roulette
Is European roulette always better than American roulette?
From an odds perspective under standard rules, European roulette is typically better because the single-zero wheel has a lower house edge (about 2.70%) than the double-zero wheel (about 5.26%). If you also find La Partage or En Prison for even-money bets, the value can improve further (to about 1.35% on those bets).
Do I need a different strategy for American roulette?
The bet types and payouts are mostly the same, so your approach can look similar. The main adjustment is selection: if you are trying to maximize value, prioritize single-zero games and favorable table rules rather than changing betting systems.
Does the “0” (or “00”) affect all bets the same way?
The presence of green pockets is what creates the house advantage across the game. Special rules like La Partage or En Prison typically apply only to even-money bets, which is why those bets benefit the most on qualifying European tables.
How can I quickly tell which roulette I’m playing?
Look at the wheel or the table layout:
- If you see only 0, it is European roulette (37 pockets).
- If you see both 0 and 00, it is American roulette (38 pockets).
Bottom line: pick the wheel that gives you the best value
The single most impactful roulette decision you can make is choosing single-zero European roulette over double-zero American roulette when you have the choice. With a house edge of about 2.70% versus about 5.26%, European roulette generally gives your bankroll more room to breathe.
For even-money bettors, the best upgrade is finding tables with La Partage or En Prison, which can reduce the effective house edge on those bets to about 1.35%. Combine that with checking table rules, comparing limits, and managing your bankroll, and you will be playing roulette in a way that is both more informed and more rewarding.
