American roulette has a standard house edge of 5.26%. The reason is simple: the wheel has 38 pockets, including both 0 and 00, but the standard payouts still look almost the same as single-zero roulette. That extra green pocket is not cosmetic. It nearly doubles the long-run cost.
Quick Facts
- American roulette has 38 pockets: 1–36, 0, and 00.
- Standard house edge: 2/38 = 5.2632%, rounded to 5.26%.
- Straight-up probability: 1/38 = 2.6316%.
- Even-money bet probability: 18/38 = 47.3684%.
- Most standard bets carry the same 5.26% edge.
- The top-line basket bet can be worse, often 7.89% under the common 6-to-1 payout.
- Compared with European roulette, American roulette charges almost double for the same basic game.
Plain Talk
American roulette is roulette with two green numbers instead of one.
Those two pockets are 0 and 00. They are the casino’s extra protection. When you bet red, black, odd, even, high, low, dozens, columns, or most inside bets, the green pockets usually make you lose.
The problem is not that double zero exists. The problem is that the payouts do not fully compensate for it.
A straight-up number still pays 35 to 1. On a European wheel, there are 36 losing outcomes against one winning outcome, so that payout is short by one unit. On an American wheel, there are 37 losing outcomes against one winning outcome, so the same payout is short by two units.
That is why American roulette is not just a different layout. It is a more expensive version of the game. The Wizard of Odds roulette basics lists the standard double-zero edge at 5.26%, and official rule sets such as the Nevada roulette rules of play show how the double-zero wheel and legal wagers are handled in live casino procedure.

How It Works
American roulette has this basic wheel structure:
| Pocket type | Count |
|---|---|
| Red numbers | 18 |
| Black numbers | 18 |
| Zero | 1 |
| Double zero | 1 |
| Total | 38 |
Now look at a red bet:
| Result | Count | Outcome |
|---|---|---|
| Red number | 18 | Win 1 unit |
| Black number | 18 | Lose 1 unit |
| 0 | 1 | Lose 1 unit |
| 00 | 1 | Lose 1 unit |
The player wins 18 ways and loses 20 ways.
That two-result gap is the edge.
| Bet type | Winning pockets | Losing pockets | Payout | Standard edge |
|---|---|---|---|---|
| Red/black | 18 | 20 | 1 to 1 | 5.26% |
| Odd/even | 18 | 20 | 1 to 1 | 5.26% |
| Dozen | 12 | 26 | 2 to 1 | 5.26% |
| Column | 12 | 26 | 2 to 1 | 5.26% |
| Straight-up | 1 | 37 | 35 to 1 | 5.26% |
| Split | 2 | 36 | 17 to 1 | 5.26% |
| Corner | 4 | 34 | 8 to 1 | 5.26% |
The top-line basket is the warning sign. On many American layouts, the 0-00-1-2-3 basket covers five numbers and pays 6 to 1. On a 38-pocket wheel, that payout is especially poor.
Roulette Table Example
You play an American double-zero table with $10 units.
You bet $10 on black for 60 spins.
| Item | Amount |
|---|---|
| Bet per spin | $10 |
| Spins | 60 |
| Total action | $600 |
| House edge | 5.26% |
| Expected loss | $31.58 |
The casino does not expect to win exactly $31.58 from you in that hour. You may win $150 or lose $250. But across enough players, enough shifts, and enough spins, that 5.26% shows up.
If the same $600 of action were played on a single-zero European wheel, the theoretical cost would be about $16.22 instead. Same color bet. Same excitement. Different price.
From the Casino Side:
A double-zero wheel is attractive to a casino because it increases theoretical win without needing a complicated game.
The dealer procedure is familiar. The layout is familiar. The player understands the bet. The extra money comes from the wheel design, not from teaching the player a new side bet.
Floor supervisors care about clean chip control, proper payout order, accurate marking of the winning number with the dolly, and table pace. Surveillance watches hand movements, late bets, dealer errors, and disputes around inside bets. Management watches drop, hold, occupancy, and average bet.
American roulette is simple to run and profitable to spread. That is why it survives even when better single-zero versions exist.
Common Mistakes
- Choosing American roulette because the minimum is lower, then betting more total action anyway.
- Thinking red/black is safer in a meaningful mathematical sense.
- Ignoring 00 because it looks like only one extra pocket.
- Playing the top-line basket without knowing its higher cost.
- Comparing sessions by buy-in instead of total amount wagered.
- Believing a lucky double-zero session proves the wheel is beatable.
- Treating all roulette wheels as if they charge the same price.
Hard Truth
Double zero is not a small rule variation. It is the casino taking the same game, keeping the same drama, and charging almost double the long-run price.
FAQ
What is the American roulette house edge?
The standard American roulette house edge is 5.26% on most bets.
Why is American roulette worse than European roulette?
American roulette has both 0 and 00. European roulette has only one zero. The payouts do not improve enough to compensate for the extra losing pocket.
Does every American roulette bet have a 5.26% edge?
Most standard bets do. The major exception is the top-line basket, which can carry a higher edge depending on the payout.
Is red/black better than betting one number?
It is lower variance, not lower house edge. Red/black wins more often but pays less. A straight-up bet wins rarely and pays more. The long-run edge is usually the same.
Can a betting system overcome the 5.26% edge?
No. A progression can change bet size and volatility, but it cannot remove the double-zero math. Read why roulette systems fail for the deeper trap.
Should beginners avoid American roulette?
If a single-zero wheel is available at a reasonable minimum, yes. The European wheel is the better mathematical choice.
Does online American roulette have the same edge?
If it uses the same 38-pocket double-zero structure and standard payouts, yes. The format may be digital, but the math is the same.
Deeper Insight
The American wheel is a good example of how casino games use small visible changes to create large financial differences.
One extra pocket does not feel dramatic. Players still see the same numbers, the same colors, the same dealer, and the same payout signs. But the long-run cost changes sharply because roulette is a high-repetition game.
The mistake is judging the wheel by a single spin. One spin is noise. A session is still noisy. A month of table results is not.
This is why casino managers think in theoretical win. They do not need every player to lose. They need enough players making enough negative-expectation wagers over enough spins.
The Massachusetts roulette rules show the same practical idea from the regulatory side: the game is controlled through defined equipment, accepted wagers, payout procedure, and settlement. The math does its work inside that procedure.
Formula / Calculation
For an even-money bet on American roulette:
$$P(win) = \frac{18}{38}$$
$$P(loss) = \frac{20}{38}$$
$$EV = \left(\frac{18}{38} \times 1\right) - \left(\frac{20}{38} \times 1\right)$$
$$EV = -\frac{2}{38} = -0.052632$$
$$House\ Edge = 5.2632% \approx 5.26%$$
For expected session loss:
$$Expected\ Loss = Total\ Amount\ Wagered \times 0.0526$$
Formula Explanation in Plain English
On a red bet, you win on 18 pockets and lose on 20 pockets. The two extra losing results are 0 and 00. Since the casino pays only even money, the player gives up 2 units across every 38 theoretical outcomes. That is 5.26% of the money bet.
