You are really asking about two different wheels
When a player asks what zero or double zero pays, they are usually standing in front of a wheel and wondering whether the green pockets are special. The short answer is that zero and double zero pay exactly what any other single number pays on that table: a straight-up bet placed directly on the number wins at 35 to 1. What changes between a wheel with one zero and a wheel with two is not the payout ratio. It is how often those green pockets appear, and that changes the rate at which the table keeps its edge.
On a European-style wheel there are 37 pockets, numbered 0 through 36, with a single green zero. On an American-style wheel there are 38 pockets, because a second green pocket, the double zero, sits opposite the single zero. Both green pockets pay the same as any other straight-up number. The difference is that the American layout gives the house one more pocket that is not part of any outside bet, and that extra pocket is the entire reason the two wheels carry different house edges.
How the straight-up payout works
A straight-up bet is a wager placed on one number, including zero or double zero. If the ball lands in that pocket, the table pays 35 to 1. The player receives back the original wager plus 35 times that amount. A one-unit bet returns 36 units in total, of which 35 units are winnings.
That 35-to-1 payout is fixed by the table rules and does not change because the number is green. The payout is also not the same as the true odds. On a European wheel, a single number has 1 chance in 37 of appearing, so the true odds are 36 to 1 against. The table pays 35 to 1, and the gap between those two figures is where the house edge comes from. On an American wheel the true odds are 37 to 1 against, while the payout stays at 35 to 1, which widens the gap.
Why the second zero matters more than the payout
The presence of a double zero does not change what a straight-up bet pays, but it changes the arithmetic of every other bet on the table. Both zero pockets sit outside the red-black, odd-even and high-low outside bets, and they also sit outside the dozen and column bets. Every time the ball lands in a green pocket, most outside wagers lose, and the player receives nothing.
On a European wheel, the single zero creates that effect once in every 37 spins on average. On an American wheel, the two green pockets create it twice in every 38 spins. The extra pocket is not a better-paying number; it is simply another losing slot for most bets. That is why the American layout carries a larger house edge across the board, even though the payout schedule printed on the felt looks almost identical.
What the two wheels compare like
| Feature | European wheel | American wheel |
|---|---|---|
| Number of pockets | 37 | 38 |
| Green pockets | Single zero only | Single zero and double zero |
| Straight-up payout on zero | 35 to 1 | 35 to 1 |
| True odds of a straight-up hit | 36 to 1 against | 37 to 1 against |
| Effect on outside bets | One green pocket outside red-black, odd-even and high-low | Two green pockets outside red-black, odd-even and high-low |
| House edge on the same bet | Lower | Higher |
The payout column is identical for both wheels. The edge column is not, because the edge comes from the number of pockets rather than the payout printed for a winning number.
How a round plays from chip to settlement
A roulette round begins when the dealer opens betting. Players place chips on the layout, either on individual numbers, on groups of numbers, or on the outside sections. The dealer spins the wheel in one direction and sends the ball travelling in the other. Once the ball slows, the dealer calls no more bets, and from that moment the layout is closed. When the ball settles in a pocket, the dealer places a marker on the winning number, clears all losing wagers, and then pays winning bets in order across the layout.
For a straight-up bet on zero or double zero, the dealer pays the winning wager at 35 to 1 and leaves the original chip in place for the player to collect with the winnings. A player who has bet on several numbers may have one winning wager and several losing ones on the same spin. The dealer settles each bet separately, so the net result of a spin is the total of all wins minus all losses, not simply the payout on the one number that hit.
The decision points that matter
Roulette has no skill-based decisions during the spin. The ball is already in motion before the layout closes, and no choice made after the spin changes anything. The decisions that matter happen before the spin, and they are about which bets to place and how much to stake on each.
The straight-up bet on a single number has the largest payout and the largest gap between true odds and payout. Outside bets such as red-black or odd-even pay even money and cover more pockets, but they still lose to the green pockets. The dozen and column bets sit in between. None of these choices changes the fact that every wager on the table carries a negative expectation on both wheel types. What changes is how fast the expectation is realised: a straight-up bet wins rarely and pays a lot, while an even-money bet wins often and pays a little.
Where the payout is printed
The payout for each bet type is printed on the table layout itself, usually in the margin or beside the bet area. The straight-up payout of 35 to 1 is standard across nearly every roulette table, but the player should always read the layout before betting, because some tables carry rule variations that affect other parts of the game. A table that offers a surrender rule on even-money bets, or an en prison rule, changes what happens to a losing outside bet when zero appears. Those rules are stated on the table or in the venue's printed game rules, and they matter more to the player than the straight-up payout, which almost never varies.
The two mistakes new players make at the zero
The first mistake is treating zero and double zero as better-paying numbers. They are not. They pay the same as any other single number, and their only special property is that they sit outside most of the outside bets. A player who loads chips onto the green pockets because they look distinctive is not getting a better deal than a player who bets on 17.
The second mistake is expecting the zeros to appear on some schedule. The wheel has no memory. A zero that has not appeared for thirty spins is not due, and a double zero that has appeared twice in a row is not less likely to appear again. Each spin is an independent event on a wheel with the same number of pockets every time, and the green pockets have the same chance of appearing on every spin as any other pocket of the same count.
FAQ
Does double zero pay more than zero?
No. Both green pockets pay 35 to 1 on a straight-up bet, the same as any other single number. The double zero does not carry a higher payout because it is a second green pocket.
What happens to an outside bet when zero hits?
On a standard table, an outside bet such as red-black, odd-even or high-low loses when the ball lands in zero or double zero. Some European tables offer a rule that returns part of the wager or holds it for the next spin when zero appears, but that rule is specific to the table and is printed in the venue's game rules.
Is it better to play a wheel with one zero or two?
A wheel with one zero has fewer pockets that sit outside the outside bets, so the house edge on the same wager is lower than on a wheel with two zeros. The payout schedule is the same, but the single-zero wheel gives the player a slower expected rate of loss on most bets.
