If you’re researching European vs American roulette for an SEO article, a casino guide, or a content refresh, the good news is that the comparison is wonderfully concrete. A few structural differences (especially the number of zeroes) create measurable changes in odds, the house edge roulette players face, and the long-term cost of play.
Below is a practical, searchable breakdown of single zero roulette vs double zero roulette, including the key numbers, what stays the same (most bets and payouts), and what changes (expected value, wheel layout, and some rule variants that can improve outcomes on even-money bets).

The core difference: single zero vs double zero
The headline difference between European and American roulette is the number of green pockets:
- European roulette has one zero (0), for a total of 37 pockets numbered 0 to 36.
- American roulette has two zeroes (0 and 00), for a total of 38 pockets numbered 0, 00, and 1 to 36.
That single extra pocket in American roulette (the 00) looks small, but it meaningfully shifts expected value. Over time, it increases the casino advantage on almost all common bets.
House edge comparison (the most searched, most important metric)
When players search for “house edge roulette” or “European vs American roulette,” they’re usually trying to answer one question: Which game gives me better odds?
Here are the typical house-edge figures you’ll see cited and used across strategy discussions:
- European roulette: approximately 2.7% house edge.
- American roulette: approximately 5.26% house edge.
In plain terms, American roulette roughly doubles the built-in cost of play compared with European roulette, assuming the same bet types and normal rules.
Even better: La Partage and en prison (European rule variants)
Some European tables add rules that improve results on even-money bets (red/black, odd/even, high/low):
- La Partage: if the ball lands on 0, you typically lose only half your even-money bet instead of the full amount.
- En prison: if the ball lands on 0, your even-money bet is “imprisoned” for the next spin, and you may recover it depending on the next outcome.
With either approach on even-money bets, the effective house edge is often about 1.35%, which is a major boost for players who prefer simple wagers like red/black.
European vs American roulette: side-by-side comparison table
| Feature | European Roulette | American Roulette |
|---|---|---|
| Zero pockets | Single zero (0) | Double zero (0 and 00) |
| Total pockets | 37 (0–36) | 38 (0, 00, 1–36) |
| Typical house edge | ~ 2.7% | ~ 5.26% |
| Even-money rule variants | Often offers La Partage or en prison on some tables | Less common for these variants; rules vary by casino |
| Bet types and payout structure | Largely identical to American roulette (the zero count changes the odds) | Largely identical to European roulette (the double zero changes the odds) |
| Wheel layout | Different number order around the wheel than American | Different number order around the wheel than European |
Wheel layout differences (and why most players don’t need to overthink them)
European and American roulette wheels use different number sequences around the wheel. This is a real, physical difference: if you compare the wheels side by side, the ordering of numbers is not the same.
What this means in practice:
- If you’re a casual player focused on odds and entertainment, the number of zero pockets matters far more than the exact number order around the wheel.
- If you’re producing research-driven content, it’s still worth noting wheel layout differences because it’s a common query and a visible distinction in casinos.
The key point for strategy-focused readers is simple: regardless of layout, a fair roulette wheel still produces outcomes where each pocket has the same probability on each spin, and the house edge is primarily driven by whether there’s one zero or two.
Are the bet types and payouts different?
In most standard casino settings, bet types and payout ratios are the same on European and American roulette. That’s important for readers because it clarifies a common misconception: the casino doesn’t need to change payouts to gain an advantage.
Typical roulette bets you’ll see on both versions include:
- Inside bets (e.g., straight-up, split, street, corner, six-line)
- Outside bets (e.g., red/black, odd/even, high/low, dozens, columns)
Because the payout structure is similar, the extra 00 in American roulette is what makes the probability math less favorable for players.
How the odds change: a simple probability view
You can make the European vs American comparison instantly understandable by focusing on what the extra pocket does to your chance of winning.
Example: even-money bets (like red/black)
Even-money bets win if the result is one of 18 outcomes (e.g., 18 red numbers) and lose otherwise.
- European roulette: 18 winning outcomes out of 37 total pockets.
- American roulette: 18 winning outcomes out of 38 total pockets.
That tiny change in denominator (37 vs 38) is enough to shift expected value and explains why the American version has a higher house edge.
Example: straight-up bet
A straight-up bet picks a single number. Your chance of hitting it is:
- 1 out of 37 in European roulette.
- 1 out of 38 in American roulette.
The payout structure may look the same, but the probability is not, which is the heart of the “single zero roulette” advantage.
Strategy implications: what smart players do differently
If you want actionable, benefit-driven advice (without overpromising), the best “strategy” is usually game selection and rule awareness rather than complex betting systems.
1) Choose European roulette when you can
When given the choice, many odds-conscious players prefer European roulette because the typical ~ 2.7% house edge is materially better than ~ 5.26% on American roulette. Over a long session, that difference can be the difference between a game that feels sustainable and one that burns through a bankroll faster.
2) Look for La Partage or en prison on even-money bets
If you enjoy straightforward betting (red/black, odd/even, high/low), tables with La Partage or en prison can improve the effective house edge on those bets to around 1.35%. That is one of the most meaningful rule-based upgrades you can highlight in an SEO article.
3) Don’t let “systems” distract from the math
Many popular betting systems change variance (how swingy results feel) but don’t eliminate the built-in edge created by the zero pockets. A clear, reader-friendly takeaway is: prioritize single zero roulette and favorable rules first, then choose bet sizes that match your comfort level.
SEO keyword targets and regional-language variants
If you’re building a search-friendly article, you can naturally incorporate high-intent terms that match what readers actually type into search engines. Core targets include:
- European vs American roulette
- single zero roulette
- double zero roulette
- house edge roulette
To capture regional intent for audiences familiar with Croatian or neighboring markets, you can also include a localized variant such as europski rulet vs američki rulet in a heading, FAQ line, or glossary-style callout, while keeping the main article in English.
FAQ: fast answers readers look for
Is European roulette always better than American roulette?
From a probability and house-edge standpoint, European roulette is typically better for players because it has one zero instead of two. That single structural difference lowers the usual house edge from about 5.26% to about 2.7%.
Do European and American roulette have different payouts?
Most standard payouts and bet types are the same, which is why the number of zero pockets is so important: the odds change while the payouts often often do not.
What’s the best rule add-on for even-money bets?
When available, La Partage or en prison can improve the effective house edge on even-money bets to around 1.35%, which is a strong benefit for simple, steady betting styles.
Bottom line: the simplest way to improve roulette odds
If your goal is to publish a clear, high-performing SEO comparison of roulette variants, anchor your content on the measurable differences:
- European roulette=single zero, 37 pockets, typical house edge of ~ 2.7% (and about 1.35% on even-money bets with La Partage or en prison).
- American roulette=double zero, 38 pockets, typical house edge of ~ 5.26%.
That’s a clean, reader-friendly conclusion that also aligns perfectly with high-intent searches like “European vs American roulette,” “single zero roulette,” “double zero roulette,” and “house edge roulette.”
