The Payout Is Fixed, the Odds Are Not
A bet on a single number in roulette pays 35 to 1 whenever your number comes up. That means a winning 10-unit wager returns 350 units in profit, plus your original 10 units back, for a total of 360 units. The payout ratio does not change between wheel types or between casinos; it is one of the oldest fixed constants in table gaming.
What does change is the probability behind that payout. A European wheel has 37 pockets, and an American wheel has 38. The payout stays at 35 to 1 either way, which is why the two wheels carry different house edges despite paying the same amount. The payout is a rule of the game; the edge is a consequence of how many losing pockets sit on the wheel.
How a Straight-Up Bet Works
A straight-up bet is a wager placed entirely inside a single numbered pocket on the layout. In most casinos you place the chip directly on the number, not touching any line around it. If the ball lands in that pocket, the dealer pays you at 35 to 1. If it lands anywhere else, the wager is collected.
The sequence of a round is the same whether you bet one number or several. You buy in at the table, receive chips in the table's own colour so the dealer can tell your bets apart from another player's, and place wagers before the dealer calls no more bets. The ball is spun, the winning number is marked on the layout, losing bets are cleared first, and winning bets are paid after. You cannot add or remove chips once the spin has begun.
One procedural point catches new players more than any other: the payout is calculated on the winning unit only, not on the total amount you had spread across the table. If you put one unit on 17 and one unit on red, and 17 comes up, the red bet also wins but at its own even-money rate. The two bets settle independently.
Comparing the Main Roulette Bets
Roulette offers more than a dozen bet types, and they do not all carry the same house edge. On a European wheel, most of the inside and outside bets share one edge, but the American wheel's extra pocket changes the picture, and one specific bet on the American layout is worse than all the others. The table below compares the common options.
| Bet type | Payout | Pockets covered | What changes between wheels |
|---|---|---|---|
| Straight-up (single number) | 35 to 1 | 1 | Payout identical; probability lower on American wheel |
| Split (two adjacent numbers) | 17 to 1 | 2 | Same payout; edge rises on American wheel |
| Street (three numbers in a row) | 11 to 1 | 3 | Same payout; edge rises on American wheel |
| Corner (four numbers) | 8 to 1 | 4 | Same payout; edge rises on American wheel |
| Six line (two rows) | 5 to 1 | 6 | Same payout; edge rises on American wheel |
| Red/black, odd/even, high/low | 1 to 1 | 18 | Same payout; edge rises on American wheel |
| Dozens and columns | 2 to 1 | 12 | Same payout; edge rises on American wheel |
| Five-number basket (0-00-1-2-3) | 6 to 1 | 5 | Exists only on the American layout; carries a higher edge than every other bet on that wheel |
The five-number basket is the one bet a new player should learn to recognise, because it is the only wager on the American layout whose house edge is materially worse than the rest of the table. It is sometimes placed by players who want to cover the zeroes and a few low numbers cheaply, but the arithmetic of the payout does not match the arithmetic of the probability as well as every other bet on the board.
Where the House Edge Comes From
The gap between the 35-to-1 payout and the true odds against hitting your number is the house edge. On a European wheel, a single number has 1 winning pocket and 36 losing pockets, so the true odds are 36 to 1 against. The casino pays only 35 to 1. That one-unit shortfall, repeated across every spin and every player, is the operator's mathematical advantage on the bet.
The American wheel adds a second zero, bringing the total to 38 pockets. A straight-up bet still pays 35 to 1, but the true odds are now 37 to 1 against. The payout did not get worse; the wheel did. The same logic applies to every other bet on the layout, which is why the American wheel carries a higher house edge across the board, and why the five-number basket is worse still.
House edge and RTP are complements: they sum to 100% for the same bet under the same rule set. If a game returns a theoretical 97.3% of wagers to players over a very large number of spins, the house edge on that game is 2.7%. Those figures are long-run statistical averages, not a prediction of any single session. A player can win on a high-edge bet for an evening and lose on a low-edge bet for a month; variance is what produces both outcomes.
What You Control at the Table
You do not control where the ball lands, and no betting pattern changes the built-in edge on any roulette wager. What you do control is which bets you place, how much you stake per spin, and how long you stay at the table. Those decisions determine how much of your bankroll is exposed to the edge per hour, not whether the edge exists.
Bet selection matters because the edge differs by wheel type and, on the American layout, by bet type. If you have a choice between tables, the wheel with fewer pockets is the lower-edge option for the same bet. If you are at an American table, avoiding the five-number basket is the single largest improvement you can make to the expected rate of loss on your action.
Stake sizing is a method of pacing, not a method of winning. A smaller unit on a straight-up bet means a smaller payout when you hit, but also a slower bleed when you do not. The payout ratio does not change with stake size; 35 to 1 is 35 to 1 whether your chip is worth one unit or one hundred. The only thing that scales is the amount of money moving across the table per spin.
Checking the Rules Before You Buy In
Roulette payouts are standard enough that you will rarely find a table deviating from the figures above, but two table-level rules are worth checking before you sit down. The first is the minimum and maximum for inside bets, which is usually printed on a small sign at the table. A straight-up bet must fall inside that range, and the range can differ between tables in the same room.
The second is the wheel itself. The layout will show a single zero or a zero and a double zero, and that visual difference tells you which house edge applies to every bet you are about to place. Some venues also run French-style tables with additional rules on even-money bets, but those rules do not change the payout on a straight-up number.
If you are playing online, the game information panel or paytable states the wheel type and the payout for each bet. Read that panel before your first spin, not after. The payout for a single number will be listed as 35 to 1, and the wheel type will be visible either in the panel or on the rendered table itself.
FAQ
Does a single-number bet pay the same on every roulette wheel?
Yes. A straight-up bet pays 35 to 1 on a European wheel, an American wheel, and any other standard layout. What changes between wheels is the probability of winning, because the American wheel has one extra pocket. The payout ratio itself is fixed.
Can I bet on more than one number at the same time?
You can place straight-up bets on as many numbers as the table maximum allows, and each bet settles independently. If one of your numbers hits, that specific wager pays 35 to 1 while the other straight-up bets are collected as losses. The payout is never multiplied across the whole spread of numbers you covered.
Why does the five-number bet pay 6 to 1 instead of 35 to 1?
The five-number basket covers five pockets rather than one, so it pays less per unit because it wins more often. The problem with the bet is not the payout in isolation but the relationship between that payout and the probability of winning. On the American layout, that relationship is worse for the five-number basket than for any other bet on the table.
