If you have ever wondered about the difference 0 vs 00 in roulette, you are already thinking about the biggest factor that separates European vs American roulette: the wheel layout, which directly drives the house edge, the RTP (return to player), and the exact probabilities of winning on every bet type.
Here is the headline takeaway for most players: European roulette has better odds than American roulette because it uses a single zero (0), while American roulette uses two green pockets (0 and 00). That one extra pocket makes a surprisingly big difference over time.
Quick comparison: European vs American roulette at a glance
- European roulette wheel: 37 pockets (numbers 1 to 36 plus a single 0)
- American roulette wheel: 38 pockets (numbers 1 to 36 plus 0 and 00)
- European roulette house edge (standard rules): about 2.70%
- American roulette house edge: about 5.26%
- Best-case boost for players: European tables that offer La Partage or En Prison can reduce the effective house edge to about 1.35% on even-money bets (like Red/Black)
So if your user intent is “which roulette has better odds”, the most consistent, practical answer is: single-zero (European) roulette is the better-value version, especially when paired with La Partage or En Prison.
Single-zero vs double-zero: why 0 vs 00 changes everything
Roulette payouts are mostly the same across variants, but the number of pockets changes the probability of landing your winning number(s). That is why the difference 0 vs 00 matters so much.
European roulette (single-zero)
European roulette has 37 equally likely outcomes on a fair wheel. For a straight-up bet (one number), you win if the ball lands on your exact number:
- Win probability: 1 / 37 (about 2.70%)
- Lose probability: 36 / 37 (about 97.30%)
American roulette (double-zero)
American roulette has 38 equally likely outcomes. A straight-up bet must now beat an extra green pocket:
- Win probability: 1 / 38 (about 2.63%)
- Lose probability: 37 / 38 (about 97.37%)
That looks like a tiny change in a single spin, but across many spins it compounds into a noticeably larger expected cost in American roulette.
House edge and RTP: the math behind “better odds”
The house edge is the casino’s long-term advantage, expressed as the average percentage of each bet that the casino expects to keep over time (assuming standard roulette payouts and a fair wheel). The RTP is the flip side: the average percentage returned to players over the long run.
European roulette house edge (single-zero)
- House edge: 1 / 37≈2.70%
- RTP: about 97.30%
American roulette house edge (double-zero)
- House edge: 2 / 38≈5.26%
- RTP: about 94.74%
In plain terms: if you can choose, European roulette gives you more play for the same bankroll because less of each wager is “priced in” as casino advantage.
Rule variations that can improve European roulette odds
Many single-zero tables (especially in European-style casinos) may offer special rules that apply to even-money outside bets such as Red/Black, Odd/Even, and High/Low. These rules can reduce the effective house edge when the ball lands on 0.
La Partage (often the best player-friendly rule)
With La Partage, if you make an even-money bet and the result is 0, you get back half of your bet instead of losing the full amount.
- Effective house edge on even-money bets: about 1.35%
En Prison (similar benefit with a “next spin” twist)
With En Prison, if you place an even-money bet and 0 hits, your bet is “imprisoned” for the next spin rather than lost immediately. If your even-money bet wins on the next spin, you typically get your original stake back (rules can vary by venue).
- Effective house edge on even-money bets: about 1.35% (when offered in its standard form)
If your goal is maximizing value, a strong practical rule is: pick single-zero roulette first, and then prioritize La Partage or En Prison if you plan to play lots of outside, even-money bets.
Odds table: European vs American roulette probabilities and payouts
Below is a straightforward odds table comparing popular bets. Payouts shown are the standard roulette payouts (the layout differences change the probabilities, not the payout schedule).
| Bet type | Covers | Typical payout | European win probability | American win probability |
|---|---|---|---|---|
| Straight-up | 1 number | 35 to 1 | 1 / 37 (2.70%) | 1 / 38 (2.63%) |
| Split | 2 numbers | 17 to 1 | 2 / 37 (5.41%) | 2 / 38 (5.26%) |
| Street | 3 numbers | 11 to 1 | 3 / 37 (8.11%) | 3 / 38 (7.89%) |
| Corner | 4 numbers | 8 to 1 | 4 / 37 (10.81%) | 4 / 38 (10.53%) |
| Six line | 6 numbers | 5 to 1 | 6 / 37 (16.22%) | 6 / 38 (15.79%) |
| Dozen | 12 numbers | 2 to 1 | 12 / 37 (32.43%) | 12 / 38 (31.58%) |
| Column | 12 numbers | 2 to 1 | 12 / 37 (32.43%) | 12 / 38 (31.58%) |
| Even-money outside | 18 numbers | 1 to 1 | 18 / 37 (48.65%) | 18 / 38 (47.37%) |
What this means in practice: the payouts stay the same, but the American wheel adds one extra losing pocket for most bet categories. That is why American roulette costs more to play over time.
Strategy outcomes: how the wheel type subtly changes your results
Roulette is a game of fixed payouts and fixed probabilities, so there is no strategy that turns roulette into a positive-expectation game under standard rules. However, your choice of variant does change expected cost and how your bankroll tends to behave.
Outside bets: smoother swings, and European rules can help more
If you like steadier variance, outside bets (Red/Black, Odd/Even, High/Low) typically produce more frequent small wins and losses. On European roulette, the single zero already improves odds compared to American, and La Partage or En Prison can improve them further for even-money bets.
Straight-up and split bets: same thrill, better value on a single-zero wheel
Inside bets like straight-up or split bets bring bigger payouts and larger swings. The excitement is similar in both variants, but the single-zero wheel gives you a higher hit rate for the same bet type.
That difference is small per spin, but if you enjoy extended sessions (or you play regularly), choosing European roulette can be a meaningful upgrade in long-run value.
Practical tips: how to pick the best roulette table
When players search “which roulette has better odds,” what they often want is a quick checklist they can use in a casino lobby or an online game list. Use these tips to make a smart, player-friendly selection.
1) Prioritize single-zero roulette (0 only)
If the wheel has 0 and 00, you are looking at the higher house edge version. If it has 0 only, you are already in better territory.
2) Look for La Partage or En Prison on even-money bets
If you mainly play outside bets, these rules can be a major advantage compared to standard rules, bringing the effective house edge on even-money bets down to about 1.35%.
3) Keep side bets in perspective
Many modern roulette offerings include optional side bets or bonus features. They can be fun, but they often come with higher house edges than the main game. If your goal is better odds, focus your bankroll on the core roulette bets and treat extras as occasional entertainment.
4) Use bankroll guardrails to play longer
- Decide your session budget up front and stick to it.
- Choose a base bet size that gives you plenty of spins.
- Set a win goal if you like structure, and be comfortable stopping when you hit it.
5) Understand that betting systems change variance, not house edge
Systems like Martingale can change how your wins and losses are distributed, but they do not change the underlying math. Your best “strategy” edge in roulette is often simply table selection: choosing European roulette over American roulette, and choosing La Partage when available.

FAQs: European vs American roulette, legality, and fairness
Which roulette has better odds?
European roulette generally has better odds because it has 37 pockets with a single 0, producing a house edge of about 2.70% under standard rules.American roulette has 38 pockets with 0 and 00, producing a house edge of about 5.26%.
Is European roulette always 2.70% house edge?
The 2.70% figure applies to standard European roulette payouts and a fair single-zero wheel. If the table offers La Partage or En Prison, the effective house edge on even-money bets can drop to about 1.35%. For non-even-money bets (like straight-up), the special rule usually does not apply.
Does American roulette ever have better odds than European roulette?
With standard rules and standard payouts, American roulette’s double-zero layout creates a higher house edge than single-zero European roulette. If you have access to a single-zero wheel, that is typically the better-value choice.
Is online roulette fair?
Fairness depends on the operator and the technology used. Online roulette is commonly offered in two ways:
- RNG roulette, which uses a random number generator to simulate outcomes.
- Live-dealer roulette, which uses a real wheel and ball streamed on video.
In regulated markets, games are generally required to meet standards designed to ensure randomness and integrity. A practical player move is to choose reputable, regulated providers where game rules and auditing practices are clearly stated.
Is roulette legal in Europe or the US?
Legality depends on where you are located and the local regulations. Roulette is legal in many jurisdictions through licensed land-based casinos, and in some places through regulated online platforms. Because laws vary widely by country, state, or region, it is best to check the rules that apply specifically to your location.
Do betting systems improve roulette odds?
Betting systems can change the pattern of wins and losses, but they do not change the underlying probabilities or the house edge. If you want better odds, the most effective step is choosing the right game variant: European roulette over American roulette, and La Partage or En Prison when available for even-money bets.
Bottom line: the smarter choice for odds-focused players
When comparing European vs American roulette, the core difference is simple but powerful: single-zero vs double-zero. European roulette’s single 0 delivers a lower house edge (about 2.70%) than American roulette’s 0 and 00 (about 5.26%). If you find a European table with La Partage or En Prison, even-money bets can become even more player-friendly, with an effective house edge around 1.35%.
If your priority is maximizing value, extending your playtime, and getting the best realistic odds roulette can offer, choose European roulette whenever you have the option.
