How Many Numbers on a Roulette Wheel? American vs. European
One of the most common questions from new players is, “are all roulette wheels numbered the same?” The answer is a definitive no, and the difference has a huge impact on your odds of winning. The key distinction lies in the number of green zero pockets.
European Roulette: The Single Zero Wheel
The European wheel is the gold standard for most players. It features 37 pockets in total: numbers 1 through 36, and a single green ‘0’. This is the standard roulette wheel numbers layout you’ll find across Europe and in most premium online casinos. When people ask how many zeros on a roulette wheel are ideal, the answer is always one, as this setup provides a lower house edge of just 2.7%.
American Roulette: The Double Zero Wheel
The American version of the game adds an extra pocket to the wheel, bringing the total to 38. In addition to numbers 1-36 and the single ‘0’, it includes a ’00’ pocket. This seemingly small change nearly doubles the house edge to a hefty 5.26%. While popular in many Las Vegas casinos, savvy players avoid this version online whenever a European wheel is available.
The Genius Behind the Sequence: Why Are the Numbers on a Roulette Wheel in That Order?
The sequence of numbers on a roulette wheel is far from random; it’s a masterpiece of balanced design intended to ensure the game is as unpredictable as possible. The layout was deliberately engineered to achieve several goals simultaneously.
- Alternating Colors: Red and black numbers alternate around the entire wheel to prevent color bias.
- High/Low Balance: High numbers (19-36) and low numbers (1-18) are distributed as evenly as possible to avoid clustering.
- Even/Odd Distribution: Similarly, even and odd numbers are spread out to prevent any section from being dominated by one type.
- Neighboring Numbers: The layout ensures that numbers that are sequential on the betting table (e.g., 5 and 6) are separated on the wheel. The famous European sequence is: 0-32-15-19-4-21-2-25-17-34-6-27-13-36-11-30-8-23-10-5-24-16-33-1-20-14-31-9-22-18-29-7-28-12-35-3-26.
This careful arrangement is the answer to how are roulette numbers on the wheel positioned—it’s all about creating perfect mathematical chaos.
Why Do Roulette Wheels Have a Zero? The House Edge Explained
The green ‘0’ (and ’00’ in American roulette) is the most important number on the wheel for the casino. It’s the source of the house edge. While you can bet on zero, it doesn’t count as Red or Black, Odd or Even, or High or Low. This means that if the ball lands on zero, all of these popular outside bets lose.
Payouts are calculated as if there were only 36 numbers. For example, a bet on a single number pays 35:1. In a “fair” game with 36 numbers, that would be correct. But with 37 or 38 numbers on the wheel, that small discrepancy gives the casino its long-term mathematical advantage. Without the zero, it would be a break-even game. With the zero, the house always has a slight edge.
Roulette Odds and Payouts
Understanding the relationship between bets, payouts, and probability is key to managing your bankroll. Inside bets offer massive payouts but are harder to hit, while outside bets offer frequent, smaller wins.
Inside Bets (Higher Payouts, Lower Odds)
Outside Bets (Lower Payouts, Higher Odds)
| Bet Name | Numbers Covered | Payout | European Odds | American Odds |
|---|---|---|---|---|
| Straight Up | 1 | 35:1 | 2.70% | 2.63% |
| Split | 2 | 17:1 | 5.41% | 5.26% |
| Street | 3 | 11:1 | 8.11% | 7.89% |
| Corner | 4 | 8:1 | 10.81% | 10.53% |
| Six Line | 6 | 5:1 | 16.22% | 15.79% |
| Column/Dozen | 12 | 2:1 | 32.43% | 31.58% |
| Red/Black | 18 | 1:1 | 48.65% | 47.37% |
| Odd/Even | 18 | 1:1 | 48.65% | 47.37% |
| Low/High (1-18/19-36) | 18 | 1:1 | 48.65% | 47.37% |
How to Play Roulette: A Step-by-Step Guide
Ready for your first spin? Here’s a simple guide to placing your first bet at a live or online roulette table.
- Find a Table: First, choose your game. We strongly recommend finding a European or French Roulette table for the best odds.
- Buy Your Chips: At a land-based casino, you’ll exchange cash for unique colored chips. Online, you simply select your chip value from the interface.
- Place Your Bets: Position your chips on the betting layout. You can place them on single numbers (inside bets) or on groups like Red/Black or Odd/Even (outside bets).
- The Spin: The dealer (or software) will spin the wheel and ball. The dealer will announce, “no more bets,” indicating the betting window is closed.
- The Result: The ball will land in a numbered pocket. The dealer places a marker, called a dolly, on the winning number on the layout.
- Payouts & Collection: The dealer clears all losing bets from the table and then pays out the winning ones. A new round of betting then begins.
Popular Roulette Variations Explained
While American and European roulette are the classics, online casinos have introduced exciting new ways to play the game.
French Roulette
This variant uses a single-zero European wheel but adds two player-friendly rules. “La Partage” (The Split) returns half your stake on even-money bets if the ball lands on zero. “En Prison” (In Prison) holds your bet for the next spin instead, giving you a second chance to win.
Lightning Roulette
Developed by Evolution Gaming, this electrifying live dealer game adds RNG “Lucky Numbers” to each round. If you have a Straight Up bet on a lucky number and it wins, you receive a multiplied payout ranging from 50x to 500x your stake!
Multi-Wheel Roulette
Why play on one wheel when you can play on up to eight at once? Multi-Wheel Roulette allows you to place a single set of bets that apply to the outcome of multiple synchronized spins, dramatically increasing the action.
5 Essential Tips for Beginners
Keep these five rules in mind to play smarter and have more fun at the tables.
- Always Choose European or French Roulette: This is the most important tip. Lowering the house edge from 5.26% to 2.7% (or 1.35%) gives you a significantly better chance of winning over time.
- Start with Outside Bets: Bets like Red/Black or Odd/Even have a nearly 50% chance of winning. They are perfect for learning the game flow without risking your bankroll too quickly.
- Understand the Odds: Memorize the payouts for key bets. Knowing that a single number pays 35:1 helps you manage your expectations and bet sizes.
- Set a Budget Before You Play: Decide on a fixed amount you are willing to lose and stick to it. This is the core principle of responsible bankroll management.
- Try for Free First: Nearly all online casinos offer a “demo” or “free play” mode. Use it to get comfortable with the interface and betting process before wagering real money.
Common Mistakes to Avoid
Even experienced players can fall into bad habits. Steer clear of these common errors to protect your bankroll and enjoy the game.
- Chasing Losses: Trying to win back money you’ve lost by increasing your bets is the fastest way to empty your wallet.
- Believing in the “Gambler’s Fallacy”: The wheel has no memory. Just because red has hit 10 times in a row doesn’t mean black is “due.” Each spin is an independent event.
- Not Knowing the Wheel Difference: Playing American roulette when a European version is available is like giving the casino a bigger tip for no reason.
- Betting More Than You Can Afford: Only ever gamble with discretionary funds that you are fully prepared to lose.
- Relying on Betting Systems: Systems like the Martingale can be fun to try but do not change the game’s odds and can be very risky if you hit a losing streak.
Bankroll Management for Roulette
Smart bankroll management is what separates casual players from disciplined ones. Set Session Limits: Before you even sit down, decide on a maximum loss amount for that session. If you hit it, walk away. No exceptions. Determine Your Unit Size: A good rule of thumb is to make your standard bet size 1-2% of your total session bankroll. This helps you withstand losing streaks. Know When to Walk Away: It’s just as important to have a win goal. Cashing out after hitting a nice profit is a great way to leave the table happy.

Frequently Asked Questions (FAQ)
What does 1st, 2nd, and 3rd 12 mean in roulette?
These refer to the “Dozen” bets on the outside of the layout. The 1st 12 covers numbers 1-12, the 2nd 12 covers 13-24, and the 3rd 12 covers 25-36. These bets pay out at 2:1 odds if the ball lands on any number within your chosen dozen.
Is there a trick to the roulette wheel?
No. Modern roulette is a game of pure chance governed by physics and random number generators (online). There are no tricks to influence the outcome. The best “trick” is to play on a wheel with the lowest house edge, like French or European Roulette, and manage your money wisely.
What does 12P, 12M, and 12D mean in roulette?
These are the French terms for the dozen bets, often seen on French Roulette tables. 12P stands for “Premier douzaine” (First dozen, 1-12). 12M is “Moyenne douzaine” (Middle dozen, 13-24). 12D is “Dernière douzaine” (Last dozen, 25-36).
What is the safest bet in roulette?
The “safest” bets are the even-money outside bets: Red/Black, Odd/Even, and High/Low (1-18/19-36). They offer the highest probability of winning (48.65% in European Roulette) but also provide the lowest payout of 1:1.
