The wheel you will most often see has an extra pocket
Walk up to a roulette table in the United States and the first thing to check is the wheel itself. Most tables use a wheel with 38 pockets: the numbers 1 through 36, a single zero, and a double zero. That second zero pocket is the defining feature of the American layout, and it is not a cosmetic difference. It changes the arithmetic on every bet you can place.
A European wheel carries 37 pockets with one zero. An American wheel carries 38 with two. The extra pocket does not add a new number to bet on; it adds a new way to lose. Every wager on the table pays as if the zero pockets were not there, while the zeros still count as losing spaces for most bets. That is where the house edge comes from, and the American layout gives the house a larger share of each wager than the single-zero alternative.
Before you buy in, look at the wheel and the felt. If you see a 00 printed on both, you are at an American table. If the layout shows only a single 0, you have found a single-zero game, which some venues offer at higher minimums or in dedicated high-limit rooms. The wheel type is the single most important fact about the game you are about to play.
What the table layout tells you before you bet
The felt in front of you is a map of every wager the table accepts. The numbered grid runs 1 through 36 in three columns, with the zero and double zero sitting at the top. Around that grid sit the outside bets: red or black, odd or even, high or low, dozens, and columns. Inside the grid are the straight-up numbers, splits, streets, corners, and six-line bets.
Every one of those bets has a different payout, and the payouts are printed on the table or available from the dealer. A straight-up number pays more than a split, a split more than a street, and so on. The payout is fixed by the number of pockets the bet covers. What the layout does not tell you is the house edge, because the edge is the same for nearly every bet on an American wheel: the two zero pockets sit outside every winning combination and collect on every spin.
| Bet type | Pockets covered | What changes on an American wheel |
|---|---|---|
| Straight-up | 1 number | Payout stays the same; two zero pockets instead of one sit outside the win |
| Split | 2 adjacent numbers | Same payout structure; extra losing pocket applies |
| Street | 3 numbers in a row | No change to payout; edge is higher because of the 00 |
| Corner | 4 numbers in a square | Same as above |
| Red/black, odd/even, high/low | 18 numbers | Pays even money; zeros are neither red nor black, odd nor even, high nor low, so both lose |
| Dozens and columns | 12 numbers | Zeros sit outside all dozens and columns |
The five-number bet deserves a separate word. On an American layout you can bet on 0, 00, 1, 2, and 3 in a single wager. It is the one bet on the table with a different, worse edge than everything else, because its payout does not match the five pockets it covers the way other inside bets do. If you are choosing bets purely on arithmetic, that is the one to leave alone.
How a spin runs
Roulette moves on a rhythm set by the dealer, and that rhythm is faster than most newcomers expect. The dealer clears losing bets, pays winners, and sends the ball around the track in the opposite direction of the spinning wheel. Between the moment the ball drops and the moment the next round of betting opens, you have a short window to place or adjust bets. The dealer controls that window.
You do not need to touch the wheel or the ball. You place chips on the felt, and the dealer handles everything else. If you want to bet, put your chips on the layout before the dealer calls for no more bets. Once the ball is in motion and the dealer signals, the betting round is closed. Late bets are returned or refused.
The pace matters because roulette is a negative-expectation game. Each spin carries the same built-in edge, and the faster the game runs, the more decisions per hour you make. A table with an empty seat next to you and a fast dealer will process more spins in the same session than a crowded table with a slower pace. You control how long you sit, how much you wager per spin, and which bets you place. You do not control the edge.
Buying in and handling chips
At a live table you do not play with the same value chips used at other games. Roulette tables issue wheel chips, which are coloured specifically for you so the dealer can tell your bets apart from everyone else's. You buy them at the table by placing cash on the felt, never into the dealer's hand. The dealer gives you a stack of your colour, and each chip carries a value that the dealer announces and records.
Those wheel chips are only good at that table. When you leave, you exchange them for regular casino chips at the same table. Do not walk away with wheel chips in your pocket; they have no value anywhere else. If you are playing on an electronic terminal or a stadium-style setup, this step disappears, because the machine tracks your balance on screen.
What stays the same no matter where you play
The wheel type changes the edge, but the structure of the game does not change. Every spin is independent. The ball has no memory. A number that has hit three times in a row is no more or less likely to hit on the next spin than any other number. The wheel does not get hot, and the table does not owe you a win because you have lost several spins in a row.
Roulette is a game of fixed probabilities and fixed payouts. The payouts are set so that the house keeps a mathematical share of every wager over a very large number of spins. In any single session, variance can put you ahead or behind by a wide margin. That variance is what makes the game exciting and what makes short-run results misleading. A player can win on a given night; the table does not become a winning proposition because of it.
What you can choose is the wheel you play, the bets you place, the size of each wager, and the length of your session. On an American layout, every bet except the five-number wager carries the same edge, so bet selection is mostly about how much variance you want: a straight-up number pays a lot and hits rarely, while an even-money bet pays a little and hits close to half the time. Neither changes the long-run rate of loss.
Where the specific numbers live
If you want the exact payout for a given bet, look at the table layout or ask the dealer. If you want the house edge printed as a percentage, the venue's game information or the help panel on an electronic game will state it. If you want to know the minimum and maximum wager, those are posted on a placard at the table, and they can change by table, by time of day, and by room. The wheel type is visible the moment you sit down; the rest is on the felt and the signage in front of you.
FAQ
Is American roulette the only version available in the United States?
No. The double-zero wheel is the most common layout, but single-zero wheels appear at some venues, often in high-limit rooms or as a dedicated table. The wheel itself tells you which game you are looking at: a 00 on the wheel and the felt means American, and a single 0 alone means European.
Do the zeros lose on every bet?
For nearly every bet, yes. On red or black, odd or even, and high or low, the zero and double zero are neither side of the wager, so they lose. On inside bets and dozens or columns, the zeros sit outside the covered numbers and lose as well. The only exception is a bet that explicitly includes a zero pocket, such as a straight-up bet on 0 or 00.
Can I use the same chips at different roulette tables?
No. The coloured wheel chips issued at a live roulette table are specific to that table and that player. You exchange them back for standard casino chips before you leave the table, and those standard chips can be used elsewhere or cashed out.
