Learn how many numbers are on roulette wheels. Compare the 37-number European layout to the 38-number American wheel and understand how it affects your odds.
How Many Numbers Are on a Roulette Wheel?
Understanding the layout of the roulette wheel is fundamental for any player. The total number of pockets depends on the specific version of the game you are playing, with two main types dominating casinos worldwide.
European and French roulette wheels feature 37 pockets, numbered from 0 to 36. The American version adds an extra pocket, numbered 00, bringing the total to 38 numbers on the wheel.
European & French Roulette: 37 Numbers
The classic European roulette wheel includes numbers 1 through 36 and a single zero. The numbers are not arranged in sequential order but are carefully placed to create a balanced distribution of red, black, odd, and even numbers around the wheel.
French roulette uses the same 37-number wheel layout. The key difference lies in the table rules, such as the 'La Partage' or 'En Prison' rules that can apply to even-money bets when the ball lands on zero.
American Roulette: 38 Numbers
American roulette wheels add a double zero (00) pocket alongside the single zero (0). This increases the total number of pockets to 38. The presence of the extra zero directly impacts the game's odds and the house edge.
For the player, the addition of the 00 pocket means there are more possible outcomes, which slightly increases the casino's advantage on most bets compared to the European version.
Why the Number Count Matters for Odds
The number of pockets on the wheel is the denominator in calculating the probability of any single number winning. In European roulette, the odds of hitting a specific number are 1 in 37, while in American roulette, they are 1 in 38.
This fundamental difference is why the house edge is lower in European roulette. Knowing the wheel type helps you understand the true odds of your bets and make more informed playing decisions.
