European and American roulette can look almost identical at a glance: a spinning wheel, a felt layout, and the same familiar red and black numbers. But if you care about value, your choice of wheel matters a lot. The biggest difference is simple and decisive: single zero vs double zero.
That one extra pocket (the 00) is the reason the house edge European vs American roulette is so different. Add in special rules like La Partage and En Prison (common on many European-style tables), and the gap can become even more meaningful for real-world play.
The core difference: 37 pockets vs 38 pockets
Both roulette variants use the same basic idea: you bet on outcomes, the ball lands in a numbered pocket, and payouts are based on the odds of that outcome. The key is how many pockets exist on the wheel.
- European roulette has 37 pockets: numbers 1–36 plus a single 0.
- American roulette has 38 pockets: numbers 1–36 plus 0 and 00.
That extra 00 doesn’t change the payouts. It changes the probability of winning your bets, which is exactly how casino advantage increases.
House edge explained (and why it’s higher on American roulette)
Roulette payouts are set as if there were only 36 numbers, but the wheel includes one or two extra green pockets. Those green pockets create the casino’s built-in edge.
Standard house edge on European roulette (single zero)
On a European wheel with 37 pockets, the standard house edge is about 2.70%. This applies broadly to typical bets because the expected return is reduced by the presence of the single 0.
Standard house edge on American roulette (double zero)
On an American wheel with 38 pockets, the standard house edge is about 5.26%. The 00 effectively doubles the disadvantage compared with the single-zero game, while payouts stay the same.
Quick comparison table: European vs American roulette
| Feature | European Roulette | American Roulette |
|---|---|---|
| Pockets | 37 (1–36, 0) | 38 (1–36, 0, 00) |
| Zero pockets | Single zero (0) | Double zero (0 and 00) |
| Typical house edge | ~ 2.70% | ~ 5.26% |
| Even-money edge with La Partage / En Prison | Can drop to ~ 1.35% on qualifying bets | Typically not offered in standard double-zero rules |
| Unique bet type | Not the same as the American “basket” bet | Includes the five-number (basket) bet |
| Who tends to prefer it | Value-seeking and odds-focused players | Common in many US casinos and venues |
La Partage and En Prison: rules that can cut the edge in half
If you’re researching La Partage En Prison rules, you’re already thinking like an advantage-minded player. These rules can significantly improve your long-term results on certain bets by softening the impact of the 0.
What bets do La Partage and En Prison apply to?
These rules are generally tied to even-money bets, such as:
- Red / Black
- Odd / Even
- 1–18 / 19–36
La Partage (how it works)
With La Partage, if you make an even-money bet and the ball lands on 0, you typically lose only half your stake (the other half is returned). Because the standard European house edge is ~ 2.70%, this rule can reduce the edge on even-money bets to roughly 1.35%.
En Prison (how it works)
With En Prison, if you place an even-money bet and the ball lands on 0, your bet is essentially “imprisoned” for the next spin instead of being lost immediately. If your bet wins on the next spin, you typically get your stake back (rather than receiving a full win). If it loses, you lose the stake. Like La Partage, the practical effect is commonly described as reducing the even-money house edge to about 1.35% on a single-zero wheel.
Benefit for players: If you prefer simpler wagers (like red or black) and want better value without changing your style, these rules can be a meaningful upgrade.
The American five-number (basket) bet: a costly option to know about
American roulette has a unique wager often called the five-number bet or basket bet. It typically covers 0, 00, 1, 2, 3.
This bet is popular because it looks like it covers “extra” outcomes. The catch is that it usually pays 6 to 1, and the math is unfavorable.
Why the basket bet increases casino advantage
On a double-zero wheel there are 38 pockets. The five-number bet wins 5 times out of 38 and loses 33 times out of 38. With a 6 to 1 payout, the house edge is about 7.89%, which is higher than the already-high 5.26% standard edge on many other American roulette bets.
Practical takeaway: If you’re comparing roulette odds and strategies, simply recognizing and avoiding the five-number bet can help you keep more of your bankroll in play over time.
Betting-table layout differences (payouts stay the same)
Even when the payouts are identical, the felt layout can differ slightly between European and American tables. The biggest visual change is the presence of 00 on American layouts.
- European layouts feature a single 0 pocket on the board.
- American layouts include both 0 and 00, which can change where certain bets are placed and how sections of the layout are arranged.
Despite these layout differences, standard payouts are consistent in the way most players experience them (for example, a straight-up number bet still pays 35 to 1). The odds behind those payouts are what change because the wheel has more pockets on the American version.
European vs American roulette: what the odds mean for your bankroll
When people search for house edge European vs American roulette, they’re often trying to answer a practical question: “Which game lets my money last longer?” While results can vary in the short term (roulette outcomes are random and streaky), the house edge is a strong indicator of what tends to happen over many spins.
- At ~2.70% (European), the casino’s long-run advantage is smaller, which is generally better for players who want more playtime per budget.
- At ~5.26% (American), the casino’s advantage is larger, so the expected cost per bet is higher over time.
- At ~1.35% on even-money bets with La Partage or En Prison, European roulette can be especially appealing to casual players who prefer straightforward bets.
Positive outcome: Choosing a single-zero wheel (and taking advantage of player-friendly rules when available) is one of the simplest “optimizations” you can make without needing complex systems or risky bet progressions.
Choosing the right wheel: a simple checklist
If you want a quick, player-friendly way to decide, use this checklist before you buy in.
Pick European roulette when you can
- You see single zero (0) and no 00 on the wheel or layout.
- The table offers La Partage or En Prison for even-money bets.
- You want the best balance of familiar gameplay and improved value.
Be extra selective with American roulette
- Expect a higher built-in cost (about 5.26% house edge).
- Avoid the five-number (basket) bet if you’re trying to keep the edge lower.
- Consider lower-volatility bet sizing if your goal is longer sessions rather than high swings.
Roulette odds and strategies: what actually helps (and what doesn’t)
Roulette is a game of independent spins: each result is not “due” or influenced by previous outcomes. That means no betting system can change the underlying house edge. Still, smart choices can improve your experience and expected cost.
Strategies that can genuinely improve value
- Choose single zero vs double zero whenever possible.
- Prioritize tables with La Partage or En Prison if you like even-money bets.
- Skip high-edge specialty bets like the American basket bet.
Strategies that are more about style than math
- Betting systems (like progressive increases after losses) may structure your session, but they do not eliminate the house edge.
- Switching between inside and outside bets changes variance (how swingy results feel), not the casino advantage on a given wheel.
The bottom line: which roulette is better for most players?
For many casual and value-seeking players, the best answer is straightforward: European roulette is typically the better choice because it uses a single zero and therefore has a lower standard house edge (about 2.70% vs about 5.26% for American roulette). If the table also offers La Partage or En Prison, the value on even-money bets can improve further, dropping to roughly 1.35% on those qualifying wagers.
American roulette remains common in many US casinos and venues, and it’s still the same iconic game. But from a pure odds perspective, the extra 00 pocket and the tempting (but costly) five-number (basket) bet are important reasons the double-zero wheel is usually less favorable.
If your goal is to get more entertainment per dollar while keeping the game simple, prioritize single zero vs double zero as your number one decision. It’s one of the rare roulette choices that can meaningfully improve your expected outcome without changing how you like to play. If you prefer other casino games, you can play blackjack.
