Roulette looks simple on the surface: place a bet, watch the wheel spin, and hope the ball lands in your zone. But when players talk about getting “better odds” in roulette, they’re usually talking about something very specific: the wheel layout and the house edge. That’s where the European vs American roulette comparison matters most.
European roulette uses a single zero wheel with 37 pockets (numbers 1 to 36 plus 0). American roulette adds a double zero (00), creating 38 pockets (1 to 36 plus 0 and 00). That one extra pocket is the whole story behind the biggest practical difference: the expected value (EV) and return to player (RTP) are meaningfully better on the single-zero game.
European vs American roulette at a glance
If you want the fastest possible way to compare the two, focus on pocket count and house edge. The payouts are typically the same, but the math behind those payouts changes when you add (or remove) a zero pocket.
| Feature | European roulette | American roulette |
|---|---|---|
| Wheel pockets | 37 (1–36 + 0) | 38 (1–36 + 0 + 00) |
| Zero pockets | Single zero (0) | Single zero (0) + double zero (00) |
| Typical house edge | About 2.7% | About 5.26% |
| Typical RTP | About 97.3% | About 94.74% |
| Where you often see it | Common across Europe and widely used online | Traditionally common in U.S. land-based casinos |
| Special rules that can reduce edge | Often offered in French roulette via La Partage or en prison (on even-money bets) | Typically not used on standard American double-zero tables |
Single zero vs double zero: why one extra pocket matters so much
Both European and American roulette keep the familiar number range of 1 through 36. Those numbers split evenly into 18 red and 18 black, plus a set of low/high and odd/even groupings. The difference is the green pocket(s):
- European roulette: one green pocket, 0
- American roulette: two green pockets, 0 and 00
Those green pockets are not “extra chances” for the player. They’re the built-in advantage for the casino. When you bet on something like red (which covers 18 numbers), you might think it’s a 50/50 proposition. It’s not:
- European roulette: red wins 18 out of 37 outcomes (about 48.65%)
- American roulette: red wins 18 out of 38 outcomes (about 47.37%)
The payout is usually still 1:1 for red/black, odd/even, and high/low. That mismatch between payout and true probability is what creates the house edge.
House edge 2.7% vs 5.26%: what it means in real play
“House edge” is a long-run average. It does not predict what will happen in a short session, but it does tell you which version is more favorable over time.
Here’s the key comparison:
- European roulette house edge: about 2.7%
- American roulette house edge: about 5.26%
That difference is large in roulette terms. It effectively means that for the same bet sizes and the same number of spins, the double-zero game takes a bigger “statistical toll” on your bankroll.
A quick expected value example (even-money bet)
Imagine you place a $10 bet on red.
- On a European wheel, the expected loss per $10 bet is about $0.27 in the long run (2.7% of $10).
- On an American wheel, the expected loss per $10 bet is about $0.53 in the long run (5.26% of $10).
Over a handful of spins, anything can happen. Over hundreds or thousands of spins, that difference becomes easier to feel. Choosing a single-zero wheel is one of the most straightforward ways to improve your expected results without changing your betting style.
Do payouts change between European and American roulette?
In most casinos, the headline payouts are the same across both versions:
- 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
- Six line (six numbers): typically pays 5 to 1
- Dozen / column: typically pays 2 to 1
- Even-money bets (red/black, odd/even, high/low): typically pay 1 to 1
So what’s different if the payouts look the same? The probability of winning each bet changes because the wheel has 37 outcomes vs 38 outcomes. With American roulette, the extra 00 outcome slightly reduces the chance of your bet hitting, while the casino keeps the same payout schedule. That’s why the RTP and house edge are less favorable.
European roulette vs American roulette odds: the “straight-up” reality check
A common point of confusion is the straight-up bet (betting a single number). Many players see “35 to 1” and assume the game is close to fair. The true odds are:
- European roulette: 1 winning pocket out of 37
- American roulette: 1 winning pocket out of 38
Even though both usually pay 35 to 1, a fair payout would need to reflect the full number of possible outcomes. That small gap between fair odds and offered payout is, again, the house edge showing up in a different outfit.
French roulette: a European variant that can improve even-money bets
French roulette is typically played on a single-zero wheel (like European roulette), but what makes it especially appealing is that it may include rules designed to soften the impact of the zero on even-money bets. The two classic rules you’ll hear about in “single zero vs double zero” discussions are La Partage and en prison.
La Partage
With La Partage, if you place an even-money bet (like red/black, odd/even, or high/low) and the ball lands on 0, you lose only half your bet instead of the full amount.
On a single-zero wheel, this rule reduces the house edge on even-money bets to about 1.35%, because the “zero penalty” is effectively cut in half.
En prison
With en prison, an even-money bet that loses to 0 is not immediately lost. Instead, it is “imprisoned” for the next spin. If your bet wins on the next spin, you get your stake back (typically with no additional profit). If it loses again, you lose the stake.
In practice, for even-money bets on a single-zero wheel, en prison produces a house edge similar to La Partage (about 1.35%), though the player experience feels different because the resolution can take an extra spin.
Important nuance: the benefit applies to even-money bets only
La Partage and en prison mainly help on even-money bets. If you’re betting dozens, columns, or inside bets, the standard single-zero house edge of about 2.7% still applies.
Where each roulette variant is typically found
Availability isn’t just trivia. It affects the choices you have, especially if you travel or switch between online and land-based play.
European roulette: common in Europe and widely offered online
European (single-zero) roulette is prevalent across European casinos, and it’s also extremely common in online casinos. If you play online and you’re optimizing for RTP, you’ll often have a strong chance of finding a single-zero table.
American roulette: traditionally common in U.S. land-based casinos
American roulette (double-zero) is historically widespread in the United States, particularly in land-based casino environments. That’s why many players’ first roulette experience in the U.S. involves the 0 and 00 layout.
Practical takeaway: if you’re in a venue with multiple roulette tables, it’s worth taking a moment to confirm whether you’re looking at a single-zero or double-zero wheel before you buy in.
How to spot a single-zero wheel quickly (and avoid accidental double-zero play)
If your goal is better expected value, the single best habit you can build is checking the wheel and layout before you place your first chip.
- Look for “00” on the felt. If you see 00, it’s American roulette.
- Check the wheel itself. The pocket markings will clearly show whether 00 exists.
- Read the table signage. Casinos often label games as “European Roulette” or “American Roulette.”
- Ask about rules. If it’s a French roulette table, ask whether La Partage or en prison is in effect for even-money bets.
This small pre-game check can be worth more than tweaking any betting pattern, because it directly changes the house edge.
Bet types and limits: what stays the same and what to watch for
The menu of bets is broadly similar in both European and American roulette. You’ll still see inside bets (numbers and small groups) and outside bets (larger groups like dozens, columns, and even-money options). The crucial difference is not the bet list, but how the added 00 affects the underlying probabilities.
Inside bets (higher variance, bigger payouts)
- Straight-up, split, street, corner, and six line bets can create big “hit moments.”
- They also tend to produce more volatile sessions because wins are less frequent.
Outside bets (more frequent wins, smaller payouts)
- Red/black, odd/even, and high/low are popular for a smoother ride.
- Dozens and columns sit in the middle with a 2:1 payout profile.
Limits matter as much as rules
Even on a favorable single-zero wheel, table limits shape your strategy and session comfort.
- Minimum bet: sets how long your bankroll can last through normal swings.
- Maximum bet: caps how aggressively you can press a perceived streak (even though outcomes are independent).
- Inside bet minimums: some tables require higher minimums for certain bet types.
If you’re choosing between two single-zero tables, a more comfortable minimum can be a real advantage for managing variance and extending playtime.
How rule differences impact player advantage (without changing your style)
Players often look for “systems” to beat roulette. The more reliable approach is simpler: choose the rule set that offers the best expected value for the exact bets you like to make.
If you prefer even-money bets
- Pick European roulette over American roulette for the lower baseline edge (about 2.7% vs 5.26%).
- If available, prefer French roulette with La Partage or en prison for an even lower edge on even-money bets (about 1.35%).
If you prefer inside bets and number hunting
- You still benefit from a single-zero wheel, because the overall house edge is lower.
- However, La Partage and en prison won’t typically improve your inside-bet edge, since those rules are aimed at even-money bets.
The most positive part of this approach is that you don’t have to change what makes roulette fun for you. You can keep your preferred bet types and simply choose the version that returns more over time.
European vs American roulette: practical tips to get the best value
If you want a player-friendly roulette experience, these tips keep you focused on what actually moves the needle.
1) Prefer single-zero wheels whenever possible
When the payouts are similar, a lower house edge is a direct upgrade. The difference between about 2.7% and 5.26% is not minor; it’s one of the clearest, simplest “better choice” decisions you’ll find in casino games.
2) Actively look for La Partage or en prison if you play outside bets
If you enjoy red/black or odd/even play, French roulette rules can be a meaningful boost. Cutting the even-money edge to about 1.35% can improve your long-run results without making the game feel complicated.
3) Match your bet selection to your comfort with variance
- If you want more frequent wins, outside bets are generally steadier.
- If you want bigger payout moments, inside bets provide that excitement with more volatility.
Neither approach is “right” universally. The winning move is choosing the wheel and rules that give you the best RTP for the style you already like.
4) Use table limits to protect your bankroll and extend playtime
Roulette can swing. A lower minimum bet can help you ride out normal variance, especially if you like making multiple bets per spin (for example, covering a handful of numbers plus an outside bet).
5) Confirm the game variant before buying in (especially in busy casinos)
In a lively casino environment, it’s easy to sit down quickly and start playing. Make checking for 00 a reflex. It’s the fastest way to avoid accidentally stepping into a higher-edge game.
FAQ: common questions about European vs American roulette
Is European roulette always better than American roulette?
From an expected value perspective, yes: a single-zero wheel generally offers a lower house edge (about 2.7%) than a double-zero wheel (about 5.26%) when standard payouts apply. That said, personal preference, availability, table limits, and atmosphere may still affect what feels “best” for a given session.
Are the odds the same if the payouts are the same?
No. The payout schedule can look identical, but the probability of winning changes because American roulette has 38 outcomes instead of 37. That’s why the same 35 to 1 straight-up payout produces a worse RTP on the double-zero wheel.
Does La Partage or en prison make roulette beatable?
They improve the player’s position on even-money bets by reducing the house edge to about 1.35% on a single-zero wheel. That’s a clear improvement, but it does not eliminate the house edge.
Do online casinos mostly offer European roulette?
Many online platforms offer European roulette prominently and black jack online because it’s popular and player-friendly in terms of RTP. Availability varies by operator and region, so it’s still smart to verify whether a table is single-zero or double-zero.
Bottom line: if you can choose, choose single zero
When you compare European vs American roulette, the headline difference is simple and powerful: single zero vs double zero. European roulette’s 37-pocket wheel produces a house edge of about 2.7%, while American roulette’s 38-pocket wheel raises it to roughly 5.26%. Payouts may look the same, but your expected value is not.
If you want to push the advantage further and you enjoy even-money bets, look for French roulette rules like La Partage or en prison. They can reduce the edge on those bets to about 1.35%, which is a meaningful step toward better RTP while keeping the game fast, social, and fun.
The most practical “winning” roulette habit isn’t a complicated system. It’s simply choosing the most favorable wheel and rules available, then playing within limits that make your session enjoyable and sustainable.
