If you’ve ever stood at a roulette table (in a casino or online) and wondered whether European roulette or American roulette is the smarter pick, you’re already thinking like a strategic player. read here Both versions look similar, use the same classic payouts (like 35:1 on a straight-up number), and deliver the same fast-paced excitement.
But one detail changes everything: the number of zeros on the wheel. That single design choice affects your winning probability on every bet and nearly doubles the casino’s built-in advantage in American roulette.
The headline difference: one zero vs two zeros
The core distinction is the wheel layout:
- European roulette uses 37 pockets: numbers 1 to 36 plus a single 0.
- American roulette uses 38 pockets: numbers 1 to 36 plus 0 and 00.
Everything else flows from that. Two zero pockets mean more ways for the house to win, while the payouts you receive stay the same.
European vs American roulette odds: how the zeros change probabilities
Roulette payouts are largely standardized across both versions. For example, a straight-up bet on a single number pays 35:1 whether you’re playing European or American roulette.
What changes is your probability of hitting the bet:
- European: your number is 1 out of 37 outcomes (1/37).
- American: your number is 1 out of 38 outcomes (1/38).
That sounds small, but over time it’s the difference between a game that’s relatively player-friendly (for a casino game) and one that’s meaningfully tougher to beat.
House edge explained (with exact percentages)
The house edge is the casino’s built-in mathematical advantage over the long run, assuming standard rules and payouts.
Here’s what the zero count does to the house edge:
- European roulette house edge: 1 zero out of 37 pockets →1/37 ≈ 2.70%
- American roulette house edge: 2 zeros out of 38 pockets →2/38 ≈ 5.26%
In practical terms, American roulette’s house edge is about nearly double European roulette’s. If your goal is to keep more of your bankroll in play for longer (and give yourself better long-run value), single-zero roulette is the clear win.

European roulette vs French roulette: same wheel, often better rules
It’s common to see French roulette grouped with European roulette, and for good reason: French roulette typically uses the same single-zero (0) wheel with 37 pockets.
The standout benefit is that many French (and some European) tables offer rules that improve the value of even-money bets (like Red/Black, Odd/Even, and High/Low). The two most famous are:
- La Partage: If you place an even-money bet and the ball lands on 0, you lose only half your bet (the other half is returned).
- 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 get your stake back (and if it loses, you lose it).
Why that matters: with a single zero, these rules can reduce the effective house edge on even-money bets from about 2.70% to approximately 1.35% under typical implementations. That’s a meaningful upgrade for players who like lower-volatility bets and longer sessions.
Table layout and markings: what looks different on the felt
Beyond the wheel itself, you’ll also notice differences on the betting layout (the table felt):
European layout
- Features a single 0 pocket on the layout.
- Often feels cleaner and slightly easier for new players to read.
- May include markings or procedures associated with French rules (especially at French roulette tables).
American layout
- Includes both 0 and 00 on the layout.
- The extra pocket is the main reason the odds are less favorable for the player.
Importantly, the presence of 00 does not increase your payout. It simply adds another losing outcome for most bets, which is why the house edge jumps.
Why the payout stays the same even when odds worsen
One of the most useful things to understand about roulette is this: the casino advantage comes from payouts that don’t fully match true odds.
Example: A straight-up bet pays 35:1. If the game were “fair” (from a pure math standpoint), you’d expect something closer to 36:1 because you’re beating 36 other outcomes. Instead, the casino keeps a small edge every spin.
In European roulette, that edge is based on one zero pocket. In American roulette, the edge is larger because it’s based on two zero pockets, while payouts remain the same.
Where you’re most likely to find each version
If you’re deciding what to play, availability matters. Here are the typical patterns:
- American roulette is most commonly found in land-based casinos in the United States.
- European roulette is widely available across Europe and is extremely common at online casinos.
- French roulette is often available in European venues and online, and it’s worth seeking out when it includes La Partage or En Prison.
If you play online, you often have the biggest advantage as a shopper: you can choose the roulette variant deliberately instead of playing whatever happens to be on the casino floor.
Practical tips: how to pick the best roulette game for your bankroll
If you want the most player-friendly roulette experience (while staying fully factual about the math), these tips make a real difference:
1) Choose single-zero (0) roulette whenever possible
This is the simplest high-impact move. A 2.70% house edge is materially better than 5.26%, and the gameplay feels nearly identical.
2) Look specifically for La Partage or En Prison on even-money bets
If you like Red/Black, Odd/Even, or High/Low, these rules can improve the effective value of those bets. Over many spins, that can mean more time at the table for the same bankroll.
3) Don’t assume “same payout” means “same game”
A straight-up bet paying 35:1 in both versions can feel equal, but the probabilities are not. Always check whether the wheel includes 00.
4) If you’re learning roulette, European layouts can be easier to start with
Fewer pockets means fewer edge cases to think about, and many players find it simpler to recognize the best-value choice quickly: avoid 00 when you can.
5) Decide what you want from the session (and match your bet types)
- For a steadier ride, many players focus on even-money bets (especially under La Partage or En Prison).
- For bigger swings and headline wins, players gravitate to inside bets (like straight-up and splits), understanding the probabilities are lower.
Common questions about European vs American roulette
Is European roulette always better than American roulette?
From a mathematical value perspective, yes: standard European roulette has a 2.70% house edge versus 5.26% for American roulette. That makes European roulette the more player-friendly option over time.
Is French roulette different from European roulette?
French roulette typically uses the same single-zero wheel as European roulette, but often includes La Partage or En Prison rules that can improve the value of even-money bets.
Do the betting options change between European and American roulette?
Most standard bets are the same (inside and outside bets), but the table markings differ because American roulette includes 00. That extra pocket is the key driver of the increased house edge.
Why do some casinos still use American roulette?
American roulette is traditional in many US casinos and is familiar to local players. For casinos, the higher house edge is also economically attractive. For players, knowing the difference helps you make an informed choice when both options are available.
The bottom line: the best choice for better odds
If you’re choosing based on odds and long-run value, the recommendation is straightforward: pick European roulette (single zero) over American roulette (double zero) whenever you can. You’ll get the same classic roulette experience, the same familiar payouts, and a substantially better mathematical position.
And if you can find a single-zero table with La Partage or En Prison for even-money bets, that’s an even more player-friendly upgrade that can help your bankroll go further while you enjoy the game.
