American Roulette Complete Guide: Rules, Bets, and House Edge

American roulette is the most expensive version of the game, and most players don’t realize it until the math catches up with them. That extra green pocket — the 00 — pushes the house edge from 2.70% (European) to 5.26%. On a $10-per-spin session, that’s the difference between losing $27 or $52.60 per thousand dollars wagered. Same table, same ball, same thrill — nearly double the cost.

This guide covers everything about American roulette: the wheel layout, every bet type and its true odds, how the double zero warps the math, and practical bankroll advice for a game that demands more discipline than its European cousin.

Understanding American Roulette Rules: What Makes It Unique?

Roulette is a game of chance where a ball spins around a wheel divided into numbered pockets. American roulette shares this fundamental premise with its European counterpart but introduces the twist that defines it: the double zero (00) pocket.

The Wheel Layout

American roulette wheels contain 38 pockets:

• Numbers 1 to 36, alternating red and black
• A single green 0 pocket
• A green 00 pocket

This contrasts with European roulette which features only one green zero pocket, totaling 37 numbers.

The additional 00 pocket is responsible for the higher house edge in American roulette. While it might seem like just one extra pocket, it significantly affects your odds.

The math works out to a $1 straight-up bet on number 7 giving you a 1 in 38 chance (about 2.63%) to win, compared to 1 in 37 (2.70%) on a European wheel. That small difference means the casino’s advantage increases substantially over many spins.

Table Layout Differences

The betting table for American roulette also reflects this double zero. You'll find a dedicated 00 spot on the layout, and the presence of 38 numbers changes the payout odds slightly compared to European roulette.

Here’s a quick breakdown of the standard American roulette table layout and notable bets:

• Straight-up bets on single numbers (including 0 and 00)
• Split bets between two adjacent numbers
• Street bets covering three numbers in a row
• Corner bets covering four numbers in a square
• Line bets for six numbers in two rows
• Outside bets like Red/Black, Odd/Even, and High/Low (1-18 or 19-36)

The betting options are the same as European roulette, but the double zero’s presence alters probabilities.

How the Game Plays Out

A typical round unfolds as follows:

1. Players place their chips on their chosen bets.
2. The dealer spins the wheel in one direction and launches the ball in the opposite direction.
3. The ball eventually lands in one of the 38 pockets.
4. Winning bets are paid according to fixed odds; losing bets are collected by the house.

This simple process repeats endlessly, but understanding the underlying math helps you grasp why some bets are riskier than others.

The House Edge: Why American Roulette Favors the Casino More

The term house edge refers to the percentage of each bet that the casino expects to keep over time. It’s built into the game’s design to ensure the casino profits in the long run.

Calculating House Edge in American Roulette

Let’s take the most straightforward bet—a straight-up bet on a single number—which pays 35:1.

• Probability of winning: 1/38 ≈ 2.63%
• Probability of losing: 37/38 ≈ 97.37%
• Expected value (EV) calculation for a $1 bet:

[ EV = (1/38) \times 35 - (37/38) \times 1 = 0.921 - 0.974 = -0.053 ]

This means, on average, you lose about 5.26 cents per dollar wagered, or a 5.26% house edge.

This figure holds for all bets on the American roulette wheel, regardless of the payout odds, because the payouts are calibrated with the double zero in mind.

Comparison With European Roulette

European roulette, with only one zero, offers a better chance for the player:

• Total pockets: 37
• Probability of winning a straight-up bet: 1/37 ≈ 2.70%
• House edge: 2.70%

The American double zero effectively doubles the house edge, making it less favorable for players who want longer sessions or lower risk.

The Impact of the Double Zero on Other Bets

Here’s a quick table showing how the double zero affects the probabilities and house edge on common bets:

This table confirms that the house edge stays consistently at 5.26% for American roulette bets due to the double zero.

Real-World Scenario: Bankroll Impact Over Time

One common situation: you play 100 spins, betting $1 on red each time. Since the house edge is 5.26%, your expected loss is:

• Total wagered: 100 × $1 = $100
• Expected loss: $100 × 5.26% = $5.26

While you might hit some winning streaks, over hundreds or thousands of spins, the $5.26 loss per $100 wagered is what the casino expects to keep on average.

Roulette Bets Explained: From the Inside to the Outside

Understanding the variety of roulette bets is essential to developing a betting approach. Each bet has its own risk profile and payout ratio.

Inside Bets

Inside bets are placed on specific numbers or small groups on the table layout. They carry higher risk but higher payout.

• Straight-up: Bet on a single number; pays 35:1.
• Split: Bet on two adjacent numbers; pays 17:1.
• Street: Bet on three numbers in a row; pays 11:1.
• Corner (Square): Bet on four numbers forming a square; pays 8:1.
• Line: Bet on two adjacent rows totaling six numbers; pays 5:1.

Inside bets are tempting due to their large payouts, but remember the 5.26% house edge applies uniformly.

Running the math on a 100-spin session… a $2 split bet between numbers 14 and 17 covers two numbers, giving a 2/38 ≈ 5.26% chance of winning, with a payout of 17:1 ($34). However, the expected loss remains 5.26% per dollar wagered, so in the long run, you’d lose about 10.5 cents on that $2 bet.

Outside Bets

Outside bets cover larger groups of numbers, with higher chances but smaller payouts.

• Red or Black: Bet on all red or all black numbers; pays 1:1.
• Odd or Even: Bet on all odd or even numbers; pays 1:1.
• Low (1-18) or High (19-36): Bet on first or second half of numbers; pays 1:1.
• Dozens: Bet on 12-number groups (1-12, 13-24, 25-36); pays 2:1.
• Columns: Bet on one of the three vertical columns; pays 2:1.

These bets reduce variance but still face the house edge from the double zero.

Payoff Table for Common Bets

This table clarifies that regardless of the bet type or coverage, the house edge remains constant at 5.26% on an American roulette wheel.

Betting Systems and the Reality of House Edge

Many players are drawn to betting systems like Martingale, Fibonacci, or D’Alembert when playing American roulette. These systems propose varying bet sizes based on previous wins or losses, aiming to recover losses or maximize winning streaks.

Why No Betting System Beats the House Edge

No betting system alters the long-term house edge. The 5.26% built into American roulette is constant because the wheel and payouts are fixed.

At a $10 minimum table, this means using the Martingale system—doubling your bet after every loss to recoup losses plus a small profit on the next win—can work in the short term, but table limits and bankroll restrictions often prevent long-term success. Losing streaks that can wipe out hundreds or thousands of dollars occur more often than most expect.

To illustrate, if you start with a $5 bet on black and lose 6 times in a row (which has a roughly 1.4% chance), you’d need to bet $320 on the 7th spin to recover losses plus profit. Many tables have maximum bet limits well below this, and most players won’t have such a large bankroll readily available.

Responsible Gambling Reminder

Playing American roulette should always be about entertainment with money you can afford to lose. Discipline, bankroll management, and setting loss limits are crucial to avoid chasing losses or getting caught up in emotional decision-making.

How to Approach American Roulette Strategically

While you can’t beat the house edge, you can control how much risk you take and how long you play.

Scenario: Playing a $100 Session

Take a player who brings $100 to a Las Vegas roulette table and decides to place $5 bets on red (an outside bet with nearly 50% chance) 20 times.

• Expected loss per bet: $5 × 5.26% = $0.263
• Expected loss over 20 spins: 20 × $0.263 = $5.26

So, on average, your $100 bankroll would decrease to roughly $94.74 after 20 spins. You might win some rounds and lose others, but the house edge means the casino expects to keep about $5.

If you place $1 straight-up bets each spin, the variance is higher—you might hit a 35:1 payout once, but it’s much less likely. The risk of losing your entire bankroll quickly is greater.

Frequently Asked Questions

What is the difference between American roulette and double zero roulette?
American roulette is sometimes called double zero roulette because it includes both a 0 and a 00 pocket on the wheel. This extra green pocket increases the number of slots from 37 to 38, raising the house edge from 2.70% in European roulette to 5.26%.

Why does American roulette have a higher house edge?
The additional 00 pocket means there are more losing pockets for most bets. The payouts remain the same as in European roulette, so the casino’s advantage increases, resulting in a house edge of 5.26% compared to 2.70% for single zero wheels.

Can I use a betting system to beat American roulette?
No betting system can overcome the built-in house edge. Systems like Martingale or Fibonacci may manage bet sizes but don’t change the odds. Over time, the house edge ensures the casino profits.

Are there bets with a lower house edge on American roulette?
Unfortunately, no. Unlike French roulette’s La Partage rule, which halves the house edge on even-money bets, American roulette maintains a 5.26% edge on all bets due to the double zero.

Is American roulette more volatile than European roulette?
Yes. The extra 00 pocket increases the chance of losing on even-money and inside bets, leading to larger swings in your bankroll. This means bigger wins and losses compared to European roulette.

Final Thoughts

Understanding American roulette’s rules, betting options, and the impact of the double zero pocket is essential for anyone looking to play this game seriously. The 5.26% house edge is a reality that no betting system can change, so the focus should be on disciplined bankroll management and enjoying the game responsibly.
