The payout depends on how many numbers your bet covers
A single number on a roulette layout pays a fixed multiple of the stake you place on it. The multiple is not a secret, and it does not change from spin to spin. It is printed on the table layout itself, and it is the same arithmetic wherever the wheel has the same number of pockets. What changes is how many numbers a bet covers, because the payout shrinks as the coverage grows.
Roulette is a game of fixed-odds bets. You are not paid according to who else is at the table or how much has been wagered before you. You are paid according to the relationship between the numbers your bet covers and the total pockets on the wheel. A bet on one number covers one pocket. A bet on red covers eighteen pockets. The first pays a much larger multiple of your stake than the second, and it wins much less often.
What the pay table looks like
Every roulette bet belongs to a family: inside bets, which sit on the numbered grid, and outside bets, which sit around its edges. Inside bets cover fewer numbers and pay larger multiples. Outside bets cover many numbers and pay smaller multiples. The table below shows the standard relationship between coverage and payout. The payout is expressed as a multiple of the stake, so a payout of 35 to 1 means a winning one-unit bet returns the original unit plus 35 more.
| Bet | Numbers covered | Payout |
|---|---|---|
| Straight up (single number) | 1 | 35 to 1 |
| Split (two adjacent numbers) | 2 | 17 to 1 |
| Street (three numbers in a row) | 3 | 11 to 1 |
| Corner (four numbers in a square) | 4 | 8 to 1 |
| Six line (two adjacent rows) | 6 | 5 to 1 |
| Dozen or column | 12 | 2 to 1 |
| Red, black, odd, even, 1-18, 19-36 | 18 | 1 to 1 |
These payouts are the same on the common wheel layouts. What differs between layouts is the number of pockets in total, and that difference changes the true odds without changing the pay table. A straight-up bet always pays 35 to 1. On a wheel with 37 pockets, a single number has one chance in 37 of appearing. On a wheel with 38 pockets, it has one chance in 38. The payout stays at 35 to 1 either way, which is why the extra pocket matters.
Why the zero is the detail that changes everything
A European-style wheel has 37 pockets: the numbers 0 through 36. An American-style wheel has 38 pockets: the same numbers plus a double zero. The extra pocket does not change any payout multiple. It changes how often any given bet wins, because every bet now has one more losing pocket working against it.
For a straight-up bet, the comparison is direct. On the 37-pocket wheel, the bet covers one pocket out of 37. On the 38-pocket wheel, it covers one pocket out of 38. The payout is identical in both cases, so the bet that faces 38 pockets is the worse proposition. The same logic applies to every bet on the layout. An even-money bet on red covers 18 pockets. On a 37-pocket wheel, 18 of the 37 pockets are red. On a 38-pocket wheel, 18 of the 38 are red. The payout is still 1 to 1, but the proportion of winning pockets has fallen.
This is the house edge expressed as structure rather than as a percentage. The casino does not need to alter the pay table to hold an advantage. It only needs the wheel to contain more pockets than the payout implies. A payout of 35 to 1 would be exactly fair if the wheel had 36 pockets. It has 37 or 38, and that gap is where the advantage lives. You do not need to memorise a percentage to see it: count the pockets, count the numbers your bet covers, and compare that ratio to the payout multiple.
How a round proceeds
You buy in at the table with cash, and the dealer exchanges it for roulette chips. These chips are often a distinct colour assigned to you alone, so the dealer can tell your bets apart from everyone else's at a glance. They carry no cash value away from the table; you exchange them back before you leave.
Once the dealer clears the previous spin and announces that bets are open, you place chips on the layout. A straight-up bet goes directly on a single number, inside the numbered grid. A split goes on the line between two numbers. A street goes on the outer edge of a row of three. Outside bets sit in the boxes around the grid.
The dealer then closes betting, spins the wheel in one direction, and sends the ball travelling in the other. When the ball settles in a pocket, the dealer marks the winning number on the layout, removes losing bets, and pays winners according to the pay table. Your winning straight-up bet returns your original chip plus 35 times its value, all in table chips. You may leave those chips in place for the next spin or pull them back.
What you control and what you do not
You control which bets you place, how much you stake on each, and how long you remain at the table. You do not control the wheel, the ball, or the sequence of outcomes. No bet selection changes the payout multiple, and no betting pattern changes the number of pockets on the wheel.
What differs between bets is how their edges and their variance behave. A straight-up bet has a large payout and a low probability of winning on any given spin. An even-money bet has a small payout and a much higher probability of winning on any given spin. Neither is a way to overcome the gap between the payout and the true odds. The choice between them is a choice about how your session will feel, not about whether the mathematics favours you.
Some players misunderstand this and treat a run of losses as information about the next spin. The wheel has no memory. A number that has not appeared for fifty spins is no more likely to appear on the fifty-first than it was on the first. The pockets do not rebalance themselves. Each spin is a fresh draw from the same set of pockets, and the payout for a winning straight-up bet is still 35 to 1 no matter what came before.
Where to find the exact rules at your table
The pay table is printed on the layout in front of you, and the wheel type is visible the moment you look at it. Count the zeroes. If there is one zero, the wheel has 37 pockets. If there are two, it has 38. That single observation tells you more about the odds you face than any sign or slogan.
Table minimums and maximums are posted at the table, usually on a small placard near the dealer. They matter for straight-up bets because a maximum on inside bets limits how much you can place on a single number. If you plan to spread bets across several numbers, check that the total sits within the table maximum. The dealer will also announce any table-specific rule, such as a rule about what happens to outside bets when the zero appears. Some layouts return half of certain even-money bets on a zero, and some do not. That rule changes the edge on those specific bets, so read the placard before you commit chips.
FAQ
Does a straight-up bet pay the same on every roulette table?
The payout multiple of 35 to 1 is standard across the common wheel layouts. What changes between tables is the number of pockets on the wheel, which alters how often the bet wins without altering the payout. Check the zeroes before you play.
Can you bet on more than one number at once?
Yes. You may place chips on as many numbers and combinations as the table maximum allows. Each bet settles independently according to its own payout multiple. A win on one number does not pay out on the other numbers you covered.
Why does a bet on a single number pay so much more than red or black?
Because it covers far fewer pockets. A straight-up bet covers one pocket, while red covers eighteen. The payout is a fixed multiple designed around that coverage, and the gap between the payout and the true odds is where the house advantage sits.
