American Roulette House Edge: 5.26%, Explained

American roulette has a house edge of 5.26% on almost every bet. The wheel carries 38 pockets, 0, 00 and 1 through 36, but winning bets are paid at odds that assume a 36-pocket wheel. That gap is the casino’s built-in advantage: over the long run it keeps about $5.26 from every $100 wagered.

This page explains where the 5.26% comes from, how it compares with European and French roulette, and what it means in real crypto stakes. It is an informational guide, not a recommendation to play. The regulator figures cited below are game-mathematics facts from a US state gaming commission and the UK Gambling Commission; they describe the game, not a recommendation to play in any specific country.

What is the house edge in American roulette?

The house edge is the percentage of each bet the casino expects to keep, on average, over a large number of spins. In American roulette it is 5.26%, which means a return to player (RTP) of 94.74%: for every 100 units staked, the game returns 94.74 and keeps 5.26 on average. The UK Gambling Commission describes roulette as a bankers’ game whose operation gives an advantage to the house.

House edge and RTP are two views of the same number. Subtract the RTP from 100% to get the edge, so a 94.74% RTP is a 5.26% edge. A Washington State Gambling Commission rules filing for Interblock roulette lists the American (double zero) game at RTP 94.74, which is exactly that 5.26% edge. For a fuller look at how the edge works across the game, see our roulette house edge explained.

Why is the American roulette house edge higher than European roulette?

American roulette adds a second green pocket, the double zero (00). That gives the wheel 38 pockets instead of the 37 on a European single-zero wheel. Because the payout table is otherwise the same, one extra losing pocket nearly doubles the house edge, from 2.70% to 5.26%. The 00 pocket is simply a second zero: another number the ball can land on that is not covered by red, black, odd, even, high or low.

The single extra zero is the whole difference. European roulette returns 97.30% (a 2.70% edge), while American roulette returns 94.74% (a 5.26% edge). That gap also compounds: over a large number of spins, a player on the American wheel loses almost twice as much as a player staking the same amount on the European wheel. If a casino offers both wheels, the European table is the cheaper game to play. You can read the full rules and bet options in our roulette guide.

How is the American roulette house edge calculated?

A straight-up bet on one number pays 35:1, so a winning bet returns 36 units including your stake. There are 38 equally likely pockets and only one pays, so the expected return is 36 divided by 38, or 94.74%. The missing 2 of 38 is the house edge: 2 / 38 = 5.26%.

The same rule works for any bet. On a 38-pocket wheel, a bet that covers N numbers and pays P to 1 has an expected return of N times (P plus 1) divided by 38. A straight-up bet gives 1 times 36 divided by 38, or 94.74%. An even-money bet gives 18 times 2 divided by 38, also 94.74%. The basket bet gives 5 times 7 divided by 38, or 92.11%.

In expected-value form, for every 1 unit staked on a single number: (1 / 38) times 35, minus (37 / 38) times 1, equals negative 2 / 38, or negative 5.26%. The minus sign is the casino’s edge.

Worked example with crypto: bet 0.001 BTC on a single number. Over 38 spins you expect one win, which returns 0.036 BTC (your 0.001 stake plus 0.035 profit), and 37 losses. You stake 0.038 BTC and get 0.036 BTC back, a shortfall of 0.002 BTC, which is 2 of 38 or 5.26%. Spreading the same stake over red or black returns the same 94.74%, because the edge does not depend on the bet type.

Why is 35:1 not a fair price on an American wheel?

A fair payout would leave no edge for either side. On a wheel with 36 numbers and no zeros, a straight-up bet paying 35:1 would be perfectly fair: the single winning pocket returns 36 units, and 36 divided by 36 is 100%. American roulette keeps that 35:1 payout but adds two zero pockets, so the same bet now returns only 36 divided by 38, or 94.74%.

The two zero pockets are the casino’s profit margin. They never pay on a straight-up bet, yet they still count as losing outcomes for red, black, odd, even, high and low. Remove the zeros and the game is break-even; add them and you get the 5.26% edge. This is also why the single-zero European wheel, with one fewer zero, is the cheaper game.

Does the house edge change between American roulette bets?

Almost every American roulette bet carries the same 5.26% edge, from even-money bets like red or black up to a straight-up number. The one exception is the five-number basket bet on 0, 00, 1, 2 and 3, which pays 6:1 and carries a worse 7.89% edge (92.11% RTP).

The basket bet is the worst option on the table. It covers five numbers out of 38 but pays only 6 to 1, so its expected return is 5 times 7 divided by 38, which is 35 / 38 or 92.11%, a house edge of 3 / 38 or 7.89%. Every other listed bet returns 36 / 38 or 94.74%. Betting on 0 or 00 as a single number is a normal straight-up bet at 5.26%. Only the five-number basket that groups those two zeros with 1, 2 and 3 carries the 7.89% edge.

Bet size does not change the edge. Whether you stake 0.0001 BTC or 0.01 BTC, the house keeps the same 5.26% of what you put down, because the edge is a percentage of the amount wagered, not a fixed fee. What changes with bet type is variance, how wild the short-term swings are, not the long-run loss.

Is American roulette worse than European or French roulette?

Yes, for most players. American roulette’s 5.26% edge is nearly double European roulette’s 2.70%, and French roulette cuts even-money bets to 1.35%, so anyone choosing between them is better off on a single-zero wheel. American roulette still suits players who want the extra 00 bet or a specific table, but it is the more expensive game.

The la partage rule matters for even-money bets only. On a single-zero wheel, refunding half of your losing bet when 0 lands cuts the even-money house edge from 2.70% to 1.35%, an RTP of 98.65%. An even-money bet returns 2 units on a win; with la partage, a zero returns half your stake instead of nothing, so the expected return on a single-zero wheel becomes (18 / 37) times 2 plus (1 / 37) times 0.5, or 98.65%. The regulator filing also lists a double-zero wheel with la partage, which cuts the even-money edge to 2.63% (97.37% RTP). Triple-zero roulette, a newer variant, adds a third green pocket and pushes the standard edge to 7.69%. If a single-zero or la partage table is available, it is the cheaper way to play the same game. Compare that with other games using our blackjack odds breakdown.

What does a 5.26% house edge mean in real money?

The edge is a long-run average, not a per-session guarantee. If you bet 0.001 BTC on a straight number 100 times, you stake 0.1 BTC in total, and 5.26% of that is about 0.00526 BTC in expected loss. The casino does not take 5.26% on every spin; the edge only shows up across thousands of spins.

Each spin can win or lose far more than the edge in the short term, which is why streaks happen. But the edge is built into the payout table, so the more you play, the closer your results drift toward that 5.26% loss. The house edge is how the casino stays profitable on a game with no skill element.

The table below shows expected loss for 1 BTC wagered in total across the wheel variants. These are round illustrative amounts, not live prices.

Because the edge means a long-run loss, only gamble with money you can afford to lose, and set deposit and loss limits before you start. If gambling stops feeling like a choice, help is available at gamblersanonymous.org and gamblingtherapy.org. Read more on setting limits in our responsible gambling guide.

Can a strategy beat the American roulette house edge?

No. Every spin is independent and every bet on the American wheel carries the same 5.26% edge, or worse on the five-number basket. No betting system, progression or money-management plan changes the expected loss, because none of them changes the payout table.

The Martingale and similar systems only reshape when losses land, not whether the casino keeps its edge. Doubling your stake after a loss does not make the next spin more likely to win, and it increases how much you risk during a losing streak. Believing a number is due after a long absence is the gambler’s fallacy: the wheel has no memory, and each spin starts fresh with the same 5.26% edge.

The reason is arithmetic. Expected loss equals the total amount you wager multiplied by 5.26%, and no ordering of bets changes that total. A system can change how losses arrive, in one large chunk or many small ones, but it cannot remove the 5.26%. No strategy beats the house edge. If a system or seller claims otherwise, treat it as a red flag. The only way to lower the edge is to choose a different wheel, such as European or French roulette, and even then the edge is never zero.

How do I check the RTP and house edge at a crypto casino?

The edge comes from the wheel and the payout table, not from the operator, so the number to check is the RTP the game provider publishes. Subtract the RTP from 100% to get the house edge. Providers name the wheel type, such as Evolution’s First Person American Roulette, described as a classic double-zero wheel. The edge is the same whether the game runs as a live table, an automatic wheel or a random-number-generator (RNG) title, because the wheel and payout table are identical; the Washington filing lists one RTP table across live, auto, video and RNG modes.

To verify the figure yourself, work through these steps.

1. Confirm the wheel. A 38-pocket wheel is American, a 37-pocket wheel is European, and a 39-pocket wheel is triple zero.
2. Find the provider’s game sheet or rules page and read the stated RTP. Subtract it from 100% to get the edge.
3. Check that the payout table matches the standard 35:1 straight-up and the figures above.
4. Confirm the casino’s licence and its terms on the regulator’s public register, and read that regulator’s complaint route.

Our guides on how we rate casinos, provably fair games and the licence explainer walk through those checks.

Why do actual results differ from the house edge?

The house edge and RTP are averages measured over a very large number of plays, not a result you should expect in any single session. The UK Gambling Commission explains that RTP is an average achieved over a significant number of game plays, and that a game returning 85% on paper does not hand back exactly 85 pence for every £1 staked in one sitting.

Short-term results swing because of variance, the natural spread of wins and losses around the average. A single straight-up bet returns 36 units or nothing, but it can never return exactly 94.74% of your stake. Only across thousands of spins does the actual return settle close to the theoretical 94.74%. Consider ten even-money bets of 0.01 BTC each. The edge predicts a long-run loss of about 0.00526 BTC, but the actual result is far noisier: win six and lose four, and you are up 0.02 BTC; win four and lose six, and you are down 0.02 BTC. Both sit well within normal short-term variance.

This is why two players can have opposite experiences on the same wheel. One may be up after an hour and the other down, even though both faced the same 5.26% edge. The edge describes the long-run drift, not the shape of any single session.
