The zero is a number first, a symbol second
When the ball lands in the green pocket, the payout depends entirely on how you bet on it. If you placed a straight-up bet on zero, it pays at the same rate as a straight-up bet on any other single number: 35 to 1. A winning one-unit bet returns 35 units in profit plus your original unit back, for 36 units total. The green colour does not change the payout. What it changes is everything else on the layout.
The zero exists to break the symmetry between the number of pockets and the payout odds. On a European wheel there are 37 pockets but a straight-up win pays only 35 to 1. On an American wheel there are 38 pockets and the same 35 to 1 payout applies. That gap between the true odds and the payout odds is the house edge, and the green pocket is where it lives. Without the zero, a straight-up bet on a 36-number wheel would pay exactly the true odds and the game would carry no built-in advantage for the operator.
How a round unfolds
You buy in at the table with cash or chips, and the dealer exchanges your money for roulette chips that carry a value marker specific to that table. These chips are not the same as cash-value chips used at other table games, which is why you must cash them in at the roulette table before you leave. You place bets on the felt until the dealer calls no more bets, the ball is sent around the wheel in the opposite direction to the spinning wheel, and it drops into a pocket. The dealer marks the winning number, clears losing bets, and pays winners from the outside in.
Every decision you make happens before the ball drops. Once the dealer calls no more bets, nothing on the layout can be changed. New players sometimes try to move a bet after the call, and the dealer will correct it or void it. A more costly mistake is leaving the table with roulette chips still in hand, because they carry no value at the cashier cage until converted at the wheel where they were issued.
What the zero pays across bet types
The zero sits at the top of the layout and participates in several different bets. Its straight-up payout is 35 to 1. It can also be part of a split, a street, a corner, or a basket bet, each with its own payout. The table below shows how the zero fits into each bet type and what each pays.
| Bet type | What it covers | Payout | How the zero fits |
|---|---|---|---|
| Straight-up | One single number | 35 to 1 | Zero alone |
| Split | Two adjacent numbers | 17 to 1 | Zero paired with 1, 2, or 3 |
| Street | Three numbers in a row | 11 to 1 | 0-1-2 or 0-2-3 on some layouts |
| Corner | Four numbers meeting at a corner | 8 to 1 | 0-1-2-3 as a block |
| Basket | 0-1-2-3 or 0-00-1-2-3 | 6 to 1 or 5 to 1 | The only five-number bet on the American layout |
The basket bet deserves special attention on an American wheel. The 0-00-1-2-3 basket pays 6 to 1, but it covers five numbers. That mismatch makes it one of the least favourable bets on the entire layout, because the payout is lower than the true odds of hitting any of those five pockets. On a European wheel the equivalent bet is the four-number 0-1-2-3 block, which pays 8 to 1 and covers four numbers, a smaller disadvantage than its American cousin.
Where the house edge comes from
Every bet on a roulette table pays less than the true odds of winning it. A straight-up bet on a European wheel has a 1 in 37 chance of winning, but it pays 35 to 1. If the payout matched the true odds, it would pay 36 to 1. That missing unit is the house edge on that bet. The same logic applies to every other bet on the layout, because the zero is present in every spin regardless of which number you choose.
The difference between wheel types is structural, not cosmetic. A European wheel has 37 pockets: the numbers 0 through 36 with a single green zero. An American wheel has 38 pockets: the same numbers plus a second green pocket marked 00. The extra pocket does not change any payout. It adds one more losing outcome to every bet, which increases the house edge across the entire table. For the same bet under the same rule set, RTP and house edge sum to 100%. Adding a pocket shifts that split in the operator's favour without changing a single payout figure.
What is and is not under your control
You choose which bets to place and how much to stake on each. What you cannot choose is the payout schedule or the number of pockets on the wheel. A bet on red pays even money, but red covers 18 numbers while the wheel has 37 or 38 pockets. The zero is not red, so it loses every even-money bet. That is the entire mechanism: the green pocket is the reason even-money bets are not even.
Some players look for patterns in past spins, but each spin is an independent event. The ball has no memory of where it landed before. A zero that has not appeared in fifty spins is not due to appear on the fifty-first. The probability of zero on any given spin is 1 in 37 on a European wheel and 1 in 38 on an American wheel, every time, regardless of history. No betting progression changes that probability. A player who doubles their stake after a loss is changing the size of their exposure, not the odds of the next spin.
Reading the table before you sit down
The wheel type is printed on the layout or visible on the wheel itself. A European wheel has one green pocket. An American wheel has two. The minimum and maximum bets are posted at the table, and the zero is always available as a straight-up bet. If you want to bet the zero, place your chip directly on the green number. If you want it covered as part of a larger bet, place the chip on the line that connects the zero to the adjacent number or numbers.
Strategy charts for roulette are not like basic-strategy charts for blackjack. Roulette has no decision after the ball is released, so there is no chart of optimal plays. What exists is a comparison of bet types by their house edge, and that comparison is fixed by the wheel and the payout table. The only meaningful choice is which bets to place and how long to play. A session that lasts longer simply exposes more wagers to the same edge.
When the dealer pays a winning straight-up bet on zero, the payout is 35 to 1. That figure is not a secret and it does not vary by casino. What varies is the wheel type, the table minimum, and the specific layout, all of which are visible before you place a single chip.
FAQ
Does zero pay the same as other single numbers?
Yes. A straight-up bet on zero pays 35 to 1, identical to a straight-up bet on any other number. The colour of the pocket has no effect on the payout.
Is betting on zero a better or worse bet than red or black?
It is a different bet with a different payout and a different probability. A straight-up bet on zero pays 35 to 1 but wins far less often than an even-money bet. The house edge on the zero bet is the same as on any other straight-up number on the same wheel.
What happens to even-money bets when zero hits?
On most layouts, even-money bets lose when the ball lands in zero. Some European tables offer a rule that returns half the stake or holds it for the next spin, but that rule is not universal and must be read from the posted table rules before you bet.
