Straight-Up Bet in Roulette: Payout and Real Odds
A straight-up bet is a chip on one number. It pays 35:1, the biggest payout on the table, and it hits about once every 38 spins on an American wheel. The payout and the odds are not the same number, and the distance between them is the house edge.
How the bet works
Place a chip squarely inside a numbered box (not touching a line). If the ball lands on that number you are paid 35:1: a $5 chip returns your $5 plus $175. Any other pocket loses the chip. You can bet 0 or 00 straight up as well; they pay the same.
| Wheel | Pays | True odds against | Win chance | House edge |
|---|---|---|---|---|
| American (0 and 00) | 35:1 | 37:1 | 2.63% | 5.26% |
| European (single 0) | 35:1 | 36:1 | 2.70% | 2.70% |
35 versus 37: where the edge lives
On a 38-pocket wheel there are 37 ways to lose and 1 way to win, so a fair payout would be 37:1. The casino pays 35:1. Those two missing units, spread across every spin, are exactly 5.26% of your action. A European wheel pays the same 35:1 against 36:1 true odds, so the gap is one unit instead of two and the edge is 2.70%. Same chip, same payout, half the cost. That is the whole case for finding a single-zero wheel.
How often will you actually hit?
Once every 38 spins on average, which at a real table's 30 to 40 spins an hour is roughly one hit per hour. The word "average" is doing heavy lifting: going 100 spins without your number is common (about a 7% chance), and so is hitting twice in ten. If you bet $5 straight up every spin for an hour, the expected cost is about $10, but the swings are enormous in both directions. Stretching a small bankroll is not what this bet is for.
Is straight-up a worse bet than red or black?
No. Same 5.26% edge as red or black on the same wheel. The difference is variance: red pays small and often, a single number pays big and rarely. Pick by how you want the night to feel, then size the bet so you can survive the dry spells. The what-to-play picker sizes it for you.
Lucky numbers and hot numbers
Every pocket has the same chance every spin. The board showing the last 20 results is a courtesy, not a forecast. A number that has "not come up in a while" is not due, and a "hot" number is not hot. If a wheel were genuinely biased, the casino's own monitoring would catch it long before a player did.

Frequently Asked Questions
What does a straight-up bet pay in roulette?
35 to 1. A $10 chip on a winning number returns $350 in winnings plus your original $10.
What are the odds of hitting a single number in roulette?
1 in 38 (2.63%) on an American wheel with 0 and 00, or 1 in 37 (2.70%) on a European single-zero wheel.
Why is the payout 35:1 if the odds are 37:1?
The gap is the house edge. A fair payout on an American wheel would be 37:1; paying 35:1 keeps 5.26% of all money bet over time. On a European wheel the true odds are 36:1, so the same payout costs 2.70%.
Can you bet on 0 or 00 straight up?
Yes. Both pay 35:1 like any other number, and they carry the same house edge. They are not a hedge against the outside bets losing; they are just two more numbers.
