The zero is a number, not a side bet
On a standard roulette layout, the zero sits at the head of the table and is treated as its own number. When a player asks what the single zero pays, they are usually asking about a straight-up bet placed directly on that pocket. The answer is the same as for any other single number on the wheel: a straight-up bet pays 35 to 1. That means a winning one-unit wager returns 35 units in profit plus the original unit, for a total of 36 units handed back.
The zero is not a special payout category. It does not pay more than the 7 or the 23. What makes the zero different is what it does to every other bet on the table when it lands, because the zero is not red, not black, not odd, not even, and not part of the high or low groups.
Why the zero changes the game's arithmetic
A European-style wheel has 37 pockets: the numbers 1 through 36 plus a single zero. A straight-up bet on any one of those pockets pays 35 to 1. If the payout were perfectly fair against 37 pockets, a winning single-number bet would pay 36 to 1. The one-unit gap between the true odds and the payout odds is the house edge on that bet.
The same gap appears on every other roulette wager, because the zero sits outside the even-money categories. A bet on red covers 18 pockets out of 37, but the payout is 1 to 1, as if the wheel had 36 pockets. When the zero lands, red, black, odd, even, high and low all lose on a European layout. That is the entire mechanism by which the house keeps an edge without altering the ball or the wheel.
An American-style wheel adds a double zero, giving 38 pockets. The straight-up payout remains 35 to 1, but the extra pocket widens the gap between true odds and payout odds on every bet. The comparison is straightforward:
| Wheel type | Pockets | Zero pockets | Straight-up payout | Effect of zero on even-money bets |
|---|---|---|---|---|
| European | 37 | 1 | 35 to 1 | Zero loses all even-money bets |
| American | 38 | 2 | 35 to 1 | Both zeros lose all even-money bets |
On some European tables, a rule called la partage or en prison applies to even-money bets when the zero lands. Under la partage, the player receives half the even-money stake back. Under en prison, the stake is held for the next spin and returned if the bet wins. These rules reduce the cost of the zero on those specific bets, but they do not change the straight-up payout and they are not offered everywhere.
The round from buy-in to settlement
A roulette round moves through a fixed sequence. The player buys in at the table, exchanging cash for wheel-specific chips that carry no value away from that table. The dealer announces that bets are open, and players place chips on the layout. Each chip position corresponds to a bet type: a single number, a split across two numbers, a street of three, a corner of four, a column, a dozen, or one of the even-money groups.
When the dealer calls no more bets, the ball is spun in the opposite direction to the wheel. Once the ball settles, the dealer marks the winning number, removes losing bets, and pays winners in order from the outside bets inward. Players may not touch chips on the layout after the call, and a player who reaches for a bet while the ball is in motion will be corrected by the dealer.
The payout structure is fixed by the table, not by the player. A straight-up bet pays 35 to 1, a split pays 17 to 1, a street pays 11 to 1, a corner pays 8 to 1, a six-line pays 5 to 1, and the outside bets pay 2 to 1 or 1 to 1. The zero participates in these payouts exactly like any other number when it is covered.
What each bet type costs over time
Different roulette bets carry different expected losses per unit wagered, but on a European wheel the house edge on most bets is identical in structure. The difference that matters to a player is variance: how often a bet pays and how much it pays when it does. A straight-up bet on the zero pays rarely but returns 35 to 1 when it hits. An even-money bet pays often but returns only the stake as profit.
The table below compares the main bet types on a European wheel, using the payout odds and the number of covered pockets. The house edge column is the same for all of them under standard rules, because the payout odds are set against 37 pockets in every case.
| Bet type | Pockets covered | Payout | How often it wins on a European wheel | Character |
|---|---|---|---|---|
| Straight-up | 1 | 35 to 1 | 1 in 37 | Rare, large payout |
| Split | 2 | 17 to 1 | 2 in 37 | Rare, medium payout |
| Street | 3 | 11 to 1 | 3 in 37 | Rare, medium payout |
| Corner | 4 | 8 to 1 | 4 in 37 | Occasional, medium payout |
| Column or dozen | 12 | 2 to 1 | 12 in 37 | Frequent, smaller payout |
| Even-money | 18 | 1 to 1 | 18 in 37 | Very frequent, smallest payout |
No bet on the table removes the zero from the wheel. Covering the zero with a straight-up bet while also betting red, for example, changes the distribution of outcomes but does not turn the combined position into a positive-expectation wager. The zero still lands on its own schedule, and the payouts remain below true odds on every component of the position.
Where the payout is printed
The payout for a straight-up bet is not something a player needs to memorise from a website. It is printed on the table layout itself, usually in the margin or on the felt near the betting area. The dealer will also announce the payout if asked before the spin. For online roulette, the game's information panel or paytable states the straight-up payout and the wheel type in use.
The wheel type matters more than the payout, because the payout is the same on both main layouts. A player who wants to know what the zero costs should check whether the wheel has one zero or two, and whether any even-money rule applies when the zero lands. Those two facts change the long-run arithmetic far more than the payout number does.
Procedural mistakes new players make
The first common mistake is placing a bet after the dealer has called no more bets. The call is not a suggestion; once it is made, the layout is closed and late chips are returned. A player who habitually places late bets slows the table and will be warned.
The second is touching chips after the ball has dropped. Winners are paid by the dealer, and a player who reaches into the layout to collect or move a bet can have the bet ruled dead. The correct move is to wait for the dealer to push the winnings forward.
The third is assuming the zero pays differently from other numbers. It does not. A player who thinks the zero is a side bet may place a straight-up chip on it without understanding that the payout is the standard 35 to 1, and that the bet loses on the other 36 pockets. The zero is a number like any other; its only special property is that it sits outside the even-money categories.
FAQ
Does the zero pay more than other numbers in roulette?
No. A straight-up bet on the zero pays 35 to 1, the same as a straight-up bet on any other single number. The zero's special role is that it loses all even-money bets on a European wheel, not that it carries a higher payout.
What happens to a red or black bet when the zero lands?
On a standard European wheel, the zero is neither red nor black, so a red or black bet loses. On some tables, a rule such as la partage returns half the even-money stake, but that rule is not universal and must be confirmed at the specific table before play.
Is betting on the zero a better strategy than betting on other numbers?
No. The zero pays the same as any other single number and has the same probability of landing on a European wheel: 1 in 37. Betting on the zero does not change the house edge or remove the house advantage; it is simply a straight-up bet on one specific pocket.
