The Double Zero Is a Pocket, Not a Special Event
When the ball settles into the double-zero pocket on an American roulette wheel, the round resolves exactly like any other losing number for most players at the table. The dealer marks the winning number, clears all losing wagers, and pays the bets that covered 00. Nothing pauses, nothing resets, and the wheel does not change its behaviour because a zero appeared.
The confusion usually comes from treating 0 and 00 as something other than numbers. They are pockets on the wheel with the same physical status as 17 or 29. What makes them different is not the outcome they produce but the bets they defeat and the edge they create for the house.
What a Double Zero Does to Each Bet Type
Roulette bets fall into two broad families: inside bets placed on the numbered grid, and outside bets placed on the surrounding boxes for red or black, odd or even, high or low, columns, and dozens. A double zero hits these families differently.
If you have a straight-up wager on 00 itself, the bet wins and pays at the table's stated odds for a single number. If you have a split, street, corner, or other inside bet that includes 00 as one of its covered numbers, that bet also wins. If your bet does not include 00, the bet loses, just as it would on any uncovered number.
Outside bets are where the double zero does its quiet work. Red or black, odd or even, and high or low all lose when 00 appears, because the pocket is neither red nor black, neither odd nor even, and neither high nor low. The same applies to 0. On an American wheel, that means two pockets defeat every even-money outside bet.
| Bet type | What happens on 00 | What it means for the player |
|---|---|---|
| Straight-up on 00 | Wins at the posted single-number payout | 00 behaves like any other number you covered |
| Split, street, corner including 00 | Wins if 00 is part of the covered group | Coverage matters, not the zero itself |
| Red or black | Loses | 00 is green, so neither colour wins |
| Odd or even | Loses | 00 is not classified as odd or even |
| High or low | Loses | 00 falls outside the 1-18 and 19-36 ranges |
| Column or dozen | Loses | 00 is not part of any column or dozen |
Why the Second Zero Changes the Game's Arithmetic
A European wheel carries 37 pockets with a single zero. An American wheel carries 38 pockets because it adds the double zero. That one extra pocket does not change how any individual bet is paid; a straight-up number pays the same posted odds on both wheels. What it changes is how often the house expects to collect losing wagers.
On a European wheel, the single zero is the only pocket that defeats all even-money outside bets. On an American wheel, both 0 and 00 defeat them. The player covering red on an American wheel is not covering 18 of 37 pockets, but 18 of 38. The house edge on that bet is larger on the American layout, and the double zero is the reason.
This does not mean the double zero appears more often than any other single number. Every pocket on a fair wheel has the same chance on any spin. The edge comes from the fact that when a zero does appear, a whole category of bets loses at once, while the payouts on winning outside bets remain unchanged.
How a Round With a Zero Plays Out
The sequence at the table is the same whether the winning number is 00, 7, or 31. The dealer calls the number, places a marker on the layout, sweeps losing bets from the felt, and then pays winning bets in a fixed order, usually starting with inside bets and moving outward. Only after all payouts are complete does the dealer clear the marker and open the next round of betting.
A new player's most common procedural mistake is reaching for chips while the marker is still on the layout. Once the ball has landed and the number is called, no further bets may be placed or changed. Reaching past the marker will get your hand waved back, and repeatedly doing it can get you removed from the table.
The second mistake is assuming a zero means everyone loses. Players with inside coverage on 0 or 00 win, and on some tables a small wager on the zero is a common way to hedge outside bets. The zero is a losing number for most of the table, but not for all of it.
The third mistake is reading a run of zeroes as meaningful. A double zero appearing twice in a short span feels unusual because humans notice patterns, but each spin is independent. The wheel does not become more or less likely to produce another zero because one just appeared.
What the Payout on 00 Is
The posted payout for a straight-up bet on 00 is the same as for any other single number on that table. The exact figure is printed on the table layout or in the game's information panel, and it is not a number you need to memorise before sitting down. What matters is that the payout is fixed for the bet type, not for the number itself. A straight-up bet on 00 pays exactly what a straight-up bet on 23 pays.
Some players assume the double zero pays more because it feels special. It does not. The specialness of 00 is structural: it is an extra green pocket that increases the house edge on outside bets. It does not carry a bonus payout, and no rule on a standard American layout treats it as a jackpot number.
Choosing Between a Single-Zero and Double-Zero Wheel
When a casino offers both layouts, the single-zero wheel is the better choice for the player on almost every bet type. The comparison is not about feel or tradition; it is about the number of pockets that defeat even-money wagers and the resulting house edge on each spin.
| Feature | European wheel | American wheel |
|---|---|---|
| Pockets | 37 | 38 |
| Zero pockets | 1 | 2 |
| Pockets defeating even-money outside bets | 1 | 2 |
| House edge on even-money bets | Lower | Higher |
| Straight-up payout for a covered number | Same posted odds | Same posted odds |
The table does not mean the American wheel is rigged or that the European wheel is generous. Both are negative-expectation games. The difference is the rate at which the house edge applies, and on the American layout that rate is higher because of the double zero.
What You Control at the Table
You cannot change the wheel, and you cannot change the fact that 00 defeats your outside bets. What you control is which bets you place, how much you wager on each, and how long you stay at the table. A player who wants to reduce the rate of expected loss on even-money bets will choose a single-zero wheel when one is available. A player who wants to cover the zero itself can place a small straight-up wager on 0 or 00, but that bet carries its own house edge and does not turn the outside bet into a positive-expectation play.
No betting pattern changes the built-in edge on any roulette bet. Doubling a losing outside bet after a zero appears does not make the next spin more likely to land red. It only changes the size of the wager. The wheel has no memory, and the double zero has no obligation to stay away because it just appeared.
FAQ
Does 00 pay more than a regular number in roulette?
No. A straight-up bet on 00 pays the same posted odds as a straight-up bet on any other single number. The payout is determined by the bet type, not by which number wins.
Why do outside bets lose on 00?
Outside bets such as red or black, odd or even, and high or low cover only the numbers that fit their category. The 00 pocket is green, is not classified as odd or even, and falls outside the high and low ranges, so it defeats all of those bets.
Is an American wheel worse for players than a European wheel?
On even-money outside bets, yes. The extra double-zero pocket means two pockets defeat those bets instead of one, which gives the house a larger edge on the American layout. The payouts on winning bets are the same on both wheels.
