Thirty-six numbered pockets, plus at least one zero
When someone asks what roulette goes up to, the short answer is 36. The numbered pockets on every standard wheel run from 0 to 36, which gives you 37 numbered positions. But the wheel does not stop at 36; it also contains at least one zero pocket, and the number of zero pockets changes the game you are playing.
A European-style wheel has a single zero. That makes 37 pockets in total: the numbers 0 through 36. An American-style wheel adds a double zero, which brings the total to 38 pockets: 0, 00, and 1 through 36. The extra pocket is not a cosmetic difference. It is the single largest factor in how much the game costs to play, because every bet on the layout pays as though the zero pockets were not there.
The table layout mirrors the wheel but arranges the numbers differently. The wheel alternates numbers around a physical circle; the table arranges them in three columns of twelve, with the zero or zeros sitting at the head of the layout. The same 36 numbers appear in both places, but the wheel controls where the ball lands and the table controls where your chips sit.
What the zero does to every bet on the layout
Roulette pays winning bets at odds that ignore the zero. A straight-up bet on a single number pays 35 to 1, as though there were 36 equally likely outcomes. But on a European wheel there are 37 pockets, and on an American wheel there are 38. The gap between the payout odds and the true odds of the pocket appearing is the house edge.
Because the zero is a pocket like any other, it can land. When it does, most bets on the layout lose outright. Some layouts offer special rules for even-money bets when zero appears, but those rules vary by table and are printed on the layout itself. The important structural point is that the zero pockets exist precisely to create the gap between what a bet pays and how often it wins.
| Wheel type | Total pockets | Zero pockets | Effect on the house edge |
|---|---|---|---|
| European | 37 | 1 (single zero) | Lower edge on the same bet |
| American | 38 | 2 (single and double zero) | Higher edge on the same bet |
The table above is deliberately qualitative. The exact house edge for a given bet depends on the specific rule set, including any special rules for even-money wagers, so the figure printed on a particular table's information panel or rules card is the one to trust. The relationship, however, is fixed: the American layout's extra pocket increases the house edge relative to the European layout for the same bet.
How a round moves from buy-in to settlement
A round of roulette has a clear sequence, and knowing it before you sit down prevents most of the confusion new players feel.
You buy in at the table by placing cash on the layout. The dealer exchanges it for roulette chips, which are different from the chips used at other table games because each player at a roulette table receives a distinct colour. That colour is how the dealer knows which stack belongs to whom when bets overlap on the layout. Roulette chips have no value away from the table; you cash them back at the same table before you leave.
Once players have chips, the dealer opens betting. You place chips directly on the layout to mark the bet you want. You may place several bets at once, and you may bet until the dealer announces that no more bets are accepted. The ball is then spun in the opposite direction to the wheel's rotation.
When the ball settles into a pocket, the dealer marks the winning number on the layout. Losing bets are cleared first, then winning bets are paid. You must not touch your chips until the dealer has finished paying and clearing, because moving them early makes it impossible to tell which bets were live. After settlement, the dealer opens betting for the next round.
The main bet types and what they mean
Roulette bets fall into two families: inside bets and outside bets. Inside bets sit on the numbered part of the layout and cover specific numbers or small groups of them. Outside bets sit around the perimeter and cover broad categories: red or black, odd or even, high or low, columns, and dozens.
Inside bets pay more because they win less often. Outside bets pay less because they win more often. Neither family is inherently better; the choice changes the shape of your session, not the underlying mathematics. A player who wants many small outcomes leans toward outside bets, while a player who accepts long dry spells in exchange for larger occasional payouts leans toward inside bets.
| Bet | What it covers | Payout shape | What changes |
|---|---|---|---|
| Straight-up | A single number | Largest payout, rarest win | Highest variance of the standard bets |
| Split | Two adjacent numbers | Mid-sized payout | Placed on the line between numbers |
| Street | Three numbers in a row | Mid-sized payout | Placed at the end of a row |
| Corner | Four numbers meeting at a corner | Mid-sized payout | Placed on the shared corner |
| Six line | Six numbers across two rows | Smaller payout | Placed at the intersection of two rows |
| Red/black, odd/even, high/low | 18 numbers each | Even-money payout | Loses to zero on most layouts |
| Dozen | 12 numbers (1-12, 13-24, 25-36) | 2 to 1 | Loses to zero on most layouts |
| Column | 12 numbers in a vertical column | 2 to 1 | Loses to zero on most layouts |
The payout figures above are the standard ratios printed on the layout. They do not change between European and American wheels. What changes is how often each bet wins, because the extra zero pocket means every bet on the American layout wins slightly less often than the same bet on the European layout.
Why the zero matters more than the number range
If you remember only one thing from this article, it should be that the question "what does roulette go up to" has two answers that point in different directions. The numbered sequence goes up to 36. The total pocket count goes up to 37 on a European wheel and 38 on an American wheel.
The distinction matters because every payout on the table is calculated as though the wheel had 36 pockets. The zero or zeros are the house's share of the arithmetic. When you choose a table, the first thing to check is not the minimum bet or the colour of the felt; it is whether the wheel has one zero or two. That single detail changes the expected rate of loss on every bet you can place.
This does not mean one wheel type is a better way to win. No wheel type changes the fact that the game has a built-in house edge on every bet. It means that, for the same bet, the European layout costs less in expected loss over a very large number of spins. That is a cost difference, not a profit opportunity.
Three procedural mistakes new players make
The first is touching chips after the ball has landed. Until the dealer has cleared losing bets and paid winners, the layout is a live accounting surface. Moving a chip early can make it impossible to reconstruct which bets were active, and the dealer will ask you to stop. Wait for the dealer to finish.
The second is placing a bet after the dealer has called no more bets. The call is not a suggestion. Once the ball is in motion and the dealer has closed betting, any chip placed on the layout is late, and the dealer will return it or treat it as void. If you want to bet on the next spin, wait until the dealer reopens betting.
The third is colour confusion. Because every player at a roulette table holds a distinct chip colour, two players can have chips on the same number. If you do not know your own colour, you cannot tell which payout is yours. Note your colour when you buy in, and watch the dealer's hands during settlement.
FAQ
Does roulette go up to 36 or 37?
The numbered sequence goes up to 36. The wheel itself has 37 pockets on a European layout because of the single zero, and 38 on an American layout because of the single and double zero.
Is the highest number on a roulette wheel the same on every wheel?
Yes. The highest numbered pocket on a standard roulette wheel is 36, regardless of whether the wheel is European or American. The difference between wheel types is in the zero pockets, not in the numbered range.
Does the extra zero change the payouts?
The payout ratios printed on the layout stay the same, but the extra zero means every bet wins slightly less often. That changes the house edge on the American layout relative to the European layout for the same bet.
