“European vs American roulette” is one of the most important comparisons you can make before you place your first chip. Both games look nearly identical at a glance: same layout, same familiar bets, and the same headline payouts on many wagers. The big difference is hidden in the wheel itself, and that small change has a major impact on your long-term results.
In this guide, you’ll get a clear, player-focused breakdown of single zero vs double zero, the roulette house edge for each version, the rule variations that can improve your odds (like en prison and la partage), and practical tips for choosing the best table online or in a land casino.
The core difference: wheel pockets (and why they matter)
Roulette is a probability game. The more pockets on the wheel, the harder it is for any single outcome to occur, and the more advantage the casino gains if payouts don’t change to compensate.
- European roulette has 37 pockets: numbers 1–36 plus a single zero (0).
- American roulette has 38 pockets: numbers 1–36 plus a single zero (0) and a double zero (00).
That one extra pocket (the 00) is the main reason American roulette is less favorable for players. Importantly, the payouts stay the same on most bets, even though the odds of winning get slightly worse.
European vs American roulette: quick comparison table
| Feature | European Roulette | American Roulette |
|---|---|---|
| Wheel pockets | 37 (1–36 + 0) | 38 (1–36 + 0 + 00) |
| Typical house edge | ~ 2.70% | ~ 5.26% |
| Straight-up payout | 35:1 | 35:1 |
| Even-money payout (red/black, odd/even, 1–18/19–36) | 1:1 | 1:1 |
| Special even-money rules | Sometimes la partage or en prison | Usually none |
| Extra bet type | Not applicable | Often includes five-number bet (0, 00, 1, 2, 3) |
Roulette house edge explained (with the actual math)
If you’re searching for “roulette house edge,” this is the key idea: the casino advantage comes from the gap between true odds and paid odds.
European roulette house edge (~ 2.70%)
Take a straight-up bet (a bet on a single number). In European roulette:
- Chance to win: 1 / 37
- Chance to lose: 36 / 37
- Payout: 35:1 (you win 35 units, plus you keep your 1-unit stake)
With a 1-unit bet, the expected value is:
EV = (1/37 * 35) + (36/37 * -1) = (35 - 36) / 37 = -1/37 ≈ -0.0270 (-2.70%)That same built-in edge applies across standard bets on a European wheel.
American roulette house edge (~ 5.26%)
In American roulette, the straight-up payout is still 35:1, but now the wheel has 38 pockets:
- Chance to win: 1 / 38
- Chance to lose: 37 / 38
EV = (1/38 * 35) + (37/38 * -1) = (35 - 37) / 38 = -2/38 ≈ -0.0526 (-5.26%)In practical terms, that’s nearly double the house edge compared to European roulette. Over many spins, this difference is meaningful for both casual sessions and higher-volume play.
Payouts that stay the same (even though your odds change)
One reason roulette feels familiar across casinos is that many payouts are standardized:
- Straight-up (single number): 35:1
- Split (two numbers): 17:1
- Street (three numbers): 11:1
- Corner (four numbers): 8:1
- Six line (six numbers): 5:1
- Dozens / Columns: 2:1
- Even-money bets (red/black, odd/even, low/high): 1:1
The payout schedule doesn’t “upgrade” to compensate for the extra 00 on American wheels, which is why the American version has a higher casino advantage.
The five-number bet: the American wager that worsens player odds
American roulette often offers a unique option called the five-number bet (also known as the basket bet). It typically covers 0, 00, 1, 2, and 3. The common payout is 6:1.
Because it involves a special combination of numbers and a payout that doesn’t match the true odds, it’s widely known as one of the least favorable bets on the roulette layout. If your goal is better value per spin, skipping the five-number bet is a simple, high-impact choice.
Rule variations that can improve European roulette odds: en prison and la partage
If you’re comparing European vs American roulette for best odds, the headline winner is usually European roulette. But there’s an extra boost: some European tables offer special rules on even-money bets when the ball lands on 0.
La partage (can reduce the edge to ~ 1.35% on even-money bets)
La partage means “sharing.” If you place an even-money bet (like red/black) and the result is 0, you lose only half your stake and get the other half back.
On a single-zero wheel, this rule can reduce the house edge on those even-money wagers from ~ 2.70% to about 1.35%.
En prison (similar effect on even-money bets)
En prison (“in prison”) is another common European rule for even-money bets. If the ball lands on 0, your even-money bet is not lost immediately. Instead, it is “imprisoned” and carried over to the next spin. If your bet wins on the next spin, you typically get your stake back (without additional profit), and if it loses, you lose the stake.
In many common implementations, en prison produces a similar player advantage to la partage on even-money bets, bringing the effective edge down to around 1.35%.
Important strategy implication: These rules help specifically on even-money bets, not on all bet types. If you love betting red/black or odd/even, it’s one of the most player-friendly rule sets you can find in standard roulette.
Single zero vs double zero: how much difference does it make for common bets?
To make the impact tangible, here is how the same bet category changes when the wheel adds the 00. The payout stays the same, but the chance of winning becomes slightly lower.
| Bet type | Numbers covered | Win probability (European 37) | Win probability (American 38) | Typical payout |
|---|---|---|---|---|
| Straight-up | 1 | 1/37 | 1/38 | 35:1 |
| Split | 2 | 2/37 | 2/38 | 17:1 |
| Corner | 4 | 4/37 | 4/38 | 8:1 |
| Dozen / Column | 12 | 12/37 | 12/38 | 2:1 |
| Even-money | 18 | 18/37 | 18/38 | 1:1 |
You’ll notice the difference looks small per spin. The advantage of European roulette is that you’re improving the math behind every bet you make, which is exactly what disciplined players look for when optimizing their sessions.
Strategy implications: choosing bets that match your goals
Roulette strategies don’t change the underlying probability, but you can still make smart choices that improve your overall experience: better odds, smoother bankroll swings, and clearer decision-making.
If your priority is best odds per spin
- Prefer European roulette over American roulette for the lower house edge.
- When available, choose European tables with la partage or en prison if you like even-money bets.
- Avoid the American five-number bet if you’re focused on value.
If your priority is lower volatility (steadier swings)
Consider leaning into even-money bets (red/black, odd/even, low/high). They win more often than inside bets, which can make sessions feel smoother. If you can pair that with la partage or en prison, you get a strong combination of frequent hits and improved rules.
If your priority is bigger hits (high volatility)
Inside bets like straight-ups, splits, and corners deliver larger payouts, but you’ll experience longer losing stretches. If you enjoy that style, choosing a single-zero wheel still helps your overall odds versus a double-zero wheel, even though the payouts are identical.
Where to find European (single-zero) vs American (double-zero) roulette
If you’re actively searching “single zero vs double zero” because you want the better version, you have more options than ever. The key is knowing what to look for.
Online casinos
Online platforms often list roulette variants by name, which makes it easier to choose the wheel you want and to play blackjack online site. You’ll commonly see separate tables labeled:
- European Roulette (single zero)
- American Roulette (double zero)
- French Roulette (single zero, often with la partage or en prison)
Many players enjoy online roulette because it’s straightforward to compare rule sets and find a table that matches their comfort level and bankroll.
Land-based casinos
In physical casinos, what’s available can depend on region, casino policy, and even the specific pit. As a general trend:
- You’re more likely to find American roulette (double zero) in many US-based venues.
- You’re more likely to find European roulette (single zero) in many European venues.
- Some casinos offer both, especially larger properties with a wide table game selection.
The best approach is simple: check the wheel or the table signage before you buy in.
How to spot a single-zero wheel quickly (practical checklist)
You don’t need to memorize probabilities at the table. You just need to confirm whether there’s a 00 pocket.
- Look at the wheel: If you see 00, it’s American roulette.
- Look at the layout: American layouts usually display both 0 and 00 at the top.
- Ask the dealer: A quick “Single zero or double zero?” gets a clear answer.
- Check the rules placard: Many casinos post table rules, including any mention of la partage or en prison.
This small habit can materially improve your long-term results, especially if roulette is a regular part of your casino routine.
European vs American roulette for different player types
Choosing the right roulette version is easier when you match it to what you value most.
Value-focused players (best odds)
If your main goal is to stretch your bankroll and get more playtime per dollar, European roulette is typically the better pick thanks to the lower house edge. If you can access French-style rules like la partage or en prison on even-money bets, that’s an additional advantage.
New players learning roulette rules
Both games are easy to learn because the bet types and payouts are familiar. European roulette is often a great “first roulette” because you’re learning the same game mechanics with improved underlying odds.
Players who prioritize table availability
Sometimes the best roulette table is simply the one you can access comfortably. If American roulette is what’s available where you play, you can still make smart choices by understanding the house edge and avoiding poor-value options like the five-number bet.
FAQ: common questions about roulette rules, odds, and edges
Is European roulette always better than American roulette?
From a mathematical standpoint, European roulette is generally better for players because the single-zero wheel produces a lower roulette house edge (~ 2.70% versus ~ 5.26% on American wheels). The gameplay and payouts feel similar, but the long-term expectation is more favorable on the European wheel.
Do payouts change between European and American roulette?
For standard bets, payouts are typically the same (for example, 35:1 on straight-up bets and 1:1 on even-money bets). The difference is that American roulette adds an extra pocket (00), which makes winning slightly less likely without increasing payouts to compensate.
What is the best roulette rule set for even-money bets?
If you enjoy red/black, odd/even, or high/low bets, look for European tables offering la partage or en prison. These rules can reduce the effective edge on even-money bets to around 1.35%, which is a meaningful improvement.
What is the five-number bet, and why do players avoid it?
The five-number bet is commonly found on American roulette and typically covers 0, 00, 1, 2, and 3. It’s often avoided because it tends to offer worse value than standard inside bets, making it less attractive for players focused on better odds.
Conclusion: which roulette version offers better odds?
If you want the most player-friendly standard roulette experience, European roulette is the clear favorite. The single zero vs double zero difference may look small on the felt, but it changes the math behind every spin: about 2.70% house edge for European roulette compared to roughly 5.26% for American roulette.
For even stronger value, keep an eye out for European tables with la partage or en prison, which can reduce the effective edge on even-money bets to around 1.35%. Combine that with a simple habit of verifying the wheel (single zero, not double zero), and you’ll be making one of the smartest choices available in roulette—without changing how fun and fast the game feels.
When your goal is better odds, longer sessions, and a more efficient bankroll, choosing the right roulette wheel is a practical advantage you can lock in before the first spin.
