If you’re comparing European vs American roulette, you’re already doing one of the smartest things a player can do: choosing the game with the most favorable math. While roulette is famously simple to play, the variant you pick can meaningfully affect your long-term results because the wheel layout changes the roulette house edge and, therefore, your expected return.

Below, you’ll find a clear, practical breakdown of double zero vs single zero, the resulting roulette odds, key rule variations, and how to pick the best roulette variant for your style.
At a Glance: European vs American Roulette
The core difference is the number of pockets on the wheel. That one design choice changes everything from probabilities to the house edge.
| Feature | European Roulette | American Roulette |
|---|---|---|
| Wheel pockets | 37 pockets (numbers 1–36 +single zero (0)) | 38 pockets (numbers 1–36 +0+double zero (00)) |
| Typical house edge | ≈ 2.70% | ≈ 5.26% |
| Why the edge differs | Fewer pockets mean slightly better probabilities for players | The extra 00 pocket increases the casino’s advantage |
| Common special rules | May include la partage or en prison on even-money bets | Typically does not offer these player-friendly rules |
| Best for | Players seeking better odds and better long-run value | Players prioritizing availability or a classic U.S. casino feel |
Wheel Layout: Single Zero vs Double Zero (The Big Difference)
Both variants use the same set of numbers 1 through 36 (18 red, 18 black). The decisive difference is the green pockets:
- European roulette has one green pocket: 0.
- American roulette has two green pockets: 0 and 00.
That extra green pocket is not just cosmetic. It reduces the probability of winning on many common bets while keeping payouts the same as European roulette. The result is a higher house edge.
Why one extra pocket matters so much
Roulette payouts generally assume a 36-number game (for example, a straight-up bet pays 35:1). When you add a 37th or 38th pocket, the payout doesn’t increase to match the new odds. That gap is the casino advantage.
Roulette House Edge and Odds (With Simple Math)
If you care about value, this is the section that makes the decision easy. The roulette house edge is approximately:
- European roulette: 1 / 37 ≈2.70%
- American roulette: 2 / 38 ≈5.26%
In practical terms, the American wheel’s house edge is almost double the European wheel’s edge. Over time, that difference can be noticeable, especially for frequent play or larger session volume.
Example: even-money bet probabilities (Red/Black, Odd/Even, High/Low)
Even-money bets are popular because they feel intuitive. Here’s what’s happening underneath:
- In European roulette, a red bet wins 18 outcomes out of 37.
- In American roulette, a red bet wins 18 outcomes out of 38.
| Bet type | European win probability | American win probability |
|---|---|---|
| Red / Black | 18 / 37 ≈48.65% | 18 / 38 ≈47.37% |
| Odd / Even | 18 / 37 ≈48.65% | 18 / 38 ≈47.37% |
| 1–18 / 19–36 | 18 / 37 ≈48.65% | 18 / 38 ≈47.37% |
Those percentages might look close at first glance, but the difference compounds across many spins. That’s why players who compare roulette odds usually prefer European rules.
Rule Variations That Can Improve the Odds (European Advantage)
Many European roulette tables offer rules that soften the impact of the zero on even-money bets (Red/Black, Odd/Even, High/Low). Two classic rules are:
La Partage
Under la partage, if you place an even-money bet and the ball lands on 0, you lose only half your bet instead of the full amount.
Benefit: This can reduce the house edge on eligible bets compared with standard European rules.
En Prison
With en prison, if you place an even-money bet and the ball lands on 0, your bet is “imprisoned” for the next spin. If your bet wins on the next spin, you typically get your stake back (without additional winnings). If it loses, you lose the stake.
Benefit: Like la partage, this can improve the effective value of even-money betting when offered under standard conditions.
Important practical note: These rules vary by casino and table. If you’re choosing the best roulette variant for odds, it’s worth checking the table rules before you play.
Strategic and Bankroll Implications (What Changes for Players)
Roulette is a negative expectation game due to the house edge, and no betting system can change the underlying math. However, choosing the better variant and using sensible bankroll structure can improve your overall experience and help your funds last longer.
1) Picking the right wheel is a “strategy” that actually works
- European roulette generally gives you more playtime per bankroll because the house edge is lower.
- American roulette tends to cost more over the long run due to the 00 pocket.
2) Even-money bets can be a smoother ride (especially with la partage / en prison)
Even-money bets usually have lower volatility than straight-up number bets. If the table also offers la partage or en prison, the experience can be even more player-friendly on those bets.
3) Volatility still matters more than “systems”
Many popular roulette strategy discussions revolve around staking systems (for example, increasing stakes after losses). These approaches may change the pattern of wins and losses, but they do not remove the house edge and can increase risk of large drawdowns. A more practical approach is to choose:
- a variant with a lower edge (often European),
- a bet type with volatility that matches your comfort level, and
- a session plan that protects your bankroll (limits and sizing).
Online Availability and Player Preference
In many online lobbies and casinos, European roulette is widely available and often presented as the default option. blackjack American roulette is also common, particularly where the classic double-zero layout is popular or where casinos mirror traditional U.S. floors.
How players typically choose
- Value-focused players: often prefer European roulette because of the lower roulette house edge.
- Tradition-focused players: may pick American roulette for familiarity and the classic 0 and 00 layout.
- Rule-seekers: look specifically for tables offering la partage or en prison on even-money bets.
Which Is the Best Roulette Variant?
If your goal is the best odds, the conclusion is straightforward:
- Best roulette variant for odds:European roulette (single zero, 37 pockets, ≈ 2.70% house edge).
- American roulette is generally less favorable because the double zero vs single zero difference increases the house edge to ≈ 5.26%.
If you have the choice between the two, European roulette is typically the better pick from a value standpoint. If you also find a European table with la partage or en prison on even-money bets, that can be an additional advantage for those specific wagers.
