The question of how many numbers are in roulette has a direct answer that defines the entire game. The total number of pockets on the wheel determines the odds, the house edge, and the potential payouts. For players, understanding this fundamental difference is the first step to making informed bets.
This review covers the two main roulette variants found in online casinos, detailing their layouts and the mathematical implications of the extra number. We'll also touch on less common versions and explain why the number count is the most critical piece of information before you place a chip.
European Roulette, the standard in most online casinos outside North America, features a wheel with 37 pockets. These are numbered from 1 to 36, alternating between red and black, plus a single green zero. French Roulette uses the same 37-number wheel but offers additional player-friendly rules like 'La Partage' or 'En Prison' on even-money bets when the zero hits.
The presence of just one zero creates a house edge of 2.70% on most bets. This means for every €100 wagered over the long term, the casino expects to retain €2.70 on average. The 37-number layout is widely considered the best version for players due to this lower mathematical advantage for the house.
American Roulette is distinguished by its wheel containing 38 pockets. It includes numbers 1 through 36 (red and black), a single zero (green), and an additional double-zero (also green). This extra double-zero pocket is the defining feature and significantly changes the game's dynamics from a player's perspective.
The additional number increases the house edge to 5.26% on most bets, almost double that of the European game. This is why experienced players generally advise choosing European or French Roulette when available. The higher edge means your bankroll is statistically likely to deplete faster playing the American version.
Some online casinos offer novelty or branded roulette games with different number sets. For example, 'Triple Zero Roulette' adds a triple-zero (000) pocket, bringing the total to 39 numbers and a house edge over 7%. These games should generally be avoided by players seeking better odds. Always check the game rules to confirm the wheel layout before playing.
The key takeaway is clear: always count the zeroes. The number of zeros on the wheel is the single biggest factor affecting your expected loss rate. For the best mathematical chance, seek out European (37 numbers) or French Roulette. This simple choice is more impactful than any betting strategy you could employ during the game itself.
Why does the zero matter so much?
The zero (and double-zero) are the numbers that cause even-money bets like Red/Black to lose. They are the pockets that give the house its mathematical edge. Without them, the game would be perfectly even for those outside bets.
Is the number sequence the same on all wheels?
No. The sequence of numbers around the wheel is carefully designed to alternate colours, high/low numbers, and odd/even numbers as much as possible. The American and European wheels have different standard sequences.
What is the payout for a number in European Roulette?
A straight-up bet on a single number in European Roulette (37 numbers) pays 35 to 1. Since the odds of winning are 1 in 37, the true odds payout would be 36 to 1. The difference is the source of the house edge.
