Picking the wrong roulette wheel is quietly costing you money every single session.
I know that sounds dramatic, but hear me out. I spent about two years just sitting down at whatever roulette table was free — American, European, didn’t matter to me. They looked basically the same. Spinning wheel, little ball, red and black numbers. Same game, right?
Wrong. Massively, embarrassingly wrong.
When I finally looked into the actual numbers behind American vs European roulette, I was genuinely annoyed at myself for how long I’d been ignoring it. The difference in house edge isn’t some tiny technical detail that only matters to statisticians. It’s the kind of difference that, over a night of play, can genuinely shift how much you lose — or keep.
So let’s get into it properly. No fluff, just the actual facts.
The Obvious Difference: That Extra Zero
Here’s the most visible difference between the two wheels, and once you see it you can’t unsee it.
- European roulette has 37 pockets: numbers 1–36 plus a single zero (0)
- American roulette has 38 pockets: numbers 1–36 plus a single zero (0) and a double zero (00)
That’s it. That’s the roulette wheel difference in its simplest form. One extra pocket on the American wheel. Doesn’t sound like much, does it?
But that one extra pocket is doing a lot of heavy lifting for the casino.
Think about it this way. Every pocket that isn’t the number you bet on is a way for you to lose. European roulette gives you 37 possible outcomes. American gives you 38. The payouts, however, stay exactly the same on both wheels. A straight-up bet on a single number pays 35 to 1 whether you’re playing American or European. So you’re getting the same reward for a bet that’s statistically harder to win on the American wheel.
The House Edge: Where It Gets Real
This is the bit that actually matters when you’re standing there with your chips deciding which table to sit at.
- European roulette house edge: 2.7%
- American roulette house edge: 5.26%
The American wheel has almost double the house edge. Almost double. On every single bet you place.
To put that into real money terms: if you’re betting £10 a spin and you play 100 spins in an evening (which is pretty easy to do, especially at a busy table), you’re wagering £1,000 in total. Statistically, European roulette is expected to cost you around £27 of that. American roulette is expected to cost you around £52.
That’s £25 of difference. For literally the same game with one extra number on the wheel. That extra pocket costs you real money every time you sit down at the wrong table.
I worked this out one evening after a particularly rough session on an American wheel at a casino in Birmingham. I’d just assumed the table was cold — bad luck, whatever. Then I went home and actually did the maths. It wasn’t cold. I’d just been playing a game with a built-in disadvantage I didn’t need to accept.
The Five-Number Bet: American Roulette’s Worst Kept Secret
American roulette has one bet that European roulette simply doesn’t offer, and it’s the worst bet on the table: the five-number bet, also called the basket bet or top line bet.
This covers 0, 00, 1, 2, and 3 in a single bet. It pays 6 to 1. Sounds reasonable on the surface — you’re covering five numbers, getting a decent payout.
The actual house edge on this bet? 7.89%.
It’s the only bet in standard roulette that has a higher house edge than everything else on the American wheel. Every other bet on an American table has that 5.26% edge. This one is even worse. There is genuinely no good reason to place it. Dealers won’t tell you this. The casino certainly won’t put it on a sign. But now you know.
Does Strategy Change Between the Two?
Honestly? Not really — and this is something a lot of people get confused about.
Whether you’re using the Martingale, the Fibonacci, flat betting, or any other system, the underlying maths doesn’t change. You’re still playing against the same house edge. Roulette strategies manage your bankroll and your session length — they don’t reduce what the casino takes per spin.
That said, the lower house edge in European roulette does mean your money lasts longer on average. Your bankroll gets eroded more slowly. So if you’re using any kind of structured betting approach, you’re getting more spins for your money, more time at the table, and more chances to run into a winning streak.
It doesn’t make the strategy work better in some magical sense. It just means you’re playing in a less hostile environment. Which, when you’re trying to enjoy yourself without haemorrhaging cash, genuinely matters.
What About La Partage and En Prison?
Some European roulette tables — particularly in French casinos or on tables running French roulette rules — offer two extra player-friendly rules worth knowing about.
- La Partage: If you’ve placed an even-money bet (red/black, odd/even, high/low) and the ball lands on zero, you get half your stake back automatically.
- En Prison: Similar situation, but instead of getting half back immediately, your bet is “imprisoned” for the next spin. If it wins, you get your full stake back. If it loses, it’s gone.
When La Partage or En Prison is in play, the house edge on even-money bets drops to 1.35%. That’s genuinely one of the best edges you’ll find on any casino table game. If you ever spot a table running these rules, sit down.
You won’t find anything like this on an American wheel. The double zero just makes the whole game more expensive by design.
So Which Is the Best Roulette to Play?
I’m not going to dress this up. If you have a choice — and at most casinos and online platforms you absolutely do — play European roulette. Every time. Full stop.
There is no scenario where American roulette is the smarter choice if European is available. The only reasons American roulette still exists are historical (it was the version that spread through the US) and because plenty of players either don’t know the difference or don’t care. The casino is happy to let that situation continue.
When I play online now, I specifically filter for European or French roulette. Most good platforms offer both, and the stakes are usually the same. When I’m in an actual casino, I’ll walk past an American table even if it means waiting for a European one to free up. That wait has saved me money more times than I can count.
If you’re playing live casino online — which I do fairly regularly — look for tables running European rules. Some live tables also run La Partage, though you might have to dig around in the game info to confirm it. Worth checking before you start throwing chips around.
A Quick Side-by-Side Summary
- European roulette: 37 pockets, single zero, 2.7% house edge, no five-number bet
- American roulette: 38 pockets, single and double zero, 5.26% house edge, five-number bet at 7.89%
- French roulette with La Partage: 37 pockets, 1.35% edge on even-money bets — the best version if you can find it
The Honest Conclusion
Look, roulette is a negative expectation game. I know that, you probably know that. The casino always has an edge, and over enough spins, that edge wins. I’m not here to pretend otherwise.
But there’s a massive difference between accepting a small, unavoidable disadvantage and voluntarily sitting down at a table with a disadvantage that’s nearly twice as bad. Understanding American vs European roulette odds is one of the genuinely simple, zero-effort things you can do to make your gambling sessions less expensive.
You don’t need to count cards. You don’t need a complicated system. You just need to look at the wheel before you sit down and make sure it only has one zero on it.
I learned this the expensive way. You don’t have to.
