Roulette Straight-Up Bet: Payout, Odds and Chip Placement
A straight-up bet is one chip on one number, placed in the middle of its box. It pays 35:1, so a winning £10 bet makes £350 profit and you get your £10 back as well: £360 in all. It’s the biggest standard payout on the table because it wins least often, once in 37 spins on a European wheel.
The basics
What Is a Straight-Up Bet in Roulette?
A straight-up bet covers one pocket on the wheel. It’s also called a straight bet or a single-number bet. You can pick any number from 1 to 36, the 0, or the 00 on an American table, and every one of them pays the same 35:1.
Where the Chip Goes
Put the chip fully inside the number’s box, in the middle. Where it sits decides the bet, so a chip that slips onto a line covers more numbers and pays less.
Quick check: if the chip touches only one number’s box, it’s a straight-up. If it sits on a line or a corner, it covers more than one number and the payout changes.
Straight-up calculator
Straight-Up Bet Calculator: Tap Your Numbers
Tap numbers on the table to place chips, then set your chip value. Each number is its own straight-up bet, so you can see what one number, a handful or the whole layout really pays.

17 lands about once every 37 spins. When it does, you get £360 back: £350 profit plus your £10. The other 36 times, you lose £10.
Try “Every number”: you win every spin and still lose one chip each time. That chip is the house edge.
Payout
What Does a 35:1 Straight-Up Payout Return?
A win gives you back 36 times your stake: 35 times it as profit, plus the stake itself. So a winning £10 straight-up pays £350 and returns your £10, £360 in total. Your stake always comes back when you win.
Simple formula: profit = stake × 35. Total back = stake × 36. The most you can win is your table’s maximum on one number times 35, so a £500 limit means a top standard win of £17,500 plus your £500.
Odds
Straight-Up Bet Odds on European and American Roulette
The payout is 35:1 on every standard wheel. What changes is how many pockets there are, and with them the chance of winning and the house edge.
*La Partage, which gives back half your stake when zero lands, only applies to even-money bets. It doesn’t help a straight-up.
Why Does the Casino Pay 35:1 Rather Than 36:1?
On a European wheel your number is one pocket out of 37, so a fair payout would be 36:1. The casino pays 35:1 and keeps the difference: one chip in every 37, which is the 2.70% house edge. American wheels add a 00 but keep the 35:1 payout, so the edge rises to 5.26%.
Best standard maths: pick a single-zero European or French table when you can. The payout is the same, but there’s no 00.

Same edge, different ride
Straight-Up vs Red: Same House Edge, Very Different Results
Bet £1 a spin for 100 spins on one number, or on red. Both lose £2.70 on average. What changes is how widely the results spread, and that’s what decides how a session feels.
Where 9 in 10 sessions finish after 100 spins
£1 a spin on a European wheel. Exact odds, not a simulation.
- Middle result
- Average (−£2.70)
- Finish ahead
- 51% vs 36% on red
- Finish exactly level
- 0% vs 8% on red
- Lose the full £100
- 6.5% vs almost never
- Average result
- −£2.70 for both
How often your number lands in 100 spins
You need at least three hits to finish ahead, because three wins return £108 for the £100 you bet.
What this means: one number finishes ahead more often than red over 100 spins, but when it goes wrong it goes badly: 6.5% of the time it never lands at all. Neither bet changes the 2.70% you lose on average.
Waiting for your number
What Is the Chance of Hitting One Number Over Several Spins?
Your number averages one hit every 37 spins, but the gaps vary a lot. Half the time it takes more than 25 spins, and one time in 10 it takes 85 or more. None of that makes it “due”: every spin is a fresh 1 in 37.

Several numbers
Can You Place Straight-Up Bets on Several Numbers?
Yes. Each number needs its own chip and is settled as its own bet. More numbers win more often, but you pay for every chip that loses, so the profit from a hit shrinks.
£1 chips on a European wheel. On an American wheel, divide the numbers covered by 38 instead of 37.
Can you bet on every number? Yes, but you can’t win. £1 on all 37 numbers costs £37 and returns £36 every spin, so you lose £1 a spin. Try it in the calculator.
Don’t confuse this with the American five-number bet. Five separate straight-ups are five ordinary bets. The American basket on 0, 00, 1, 2 and 3 is one special bet that pays 6:1, with a 7.89% house edge, the worst on the table. See our roulette wheel and table guide.
Multiplier games
Straight-Up Payouts in Lightning and Other Multiplier Games
In multiplier roulette, straight-ups can win far more than 35:1 when a boost lands. To pay for the boosts, a normal straight-up win pays less. Always check the paytable in the game’s help screen.
Payouts from the providers’ game pages where they publish them, and from published game guides where they don’t, checked 4 October 2026. Casino links go to UK-licensed casinos that list each game.
Zero and double zero
A straight-up on 0 pays the same 35:1 as a straight-up on 17 or 26, and so does 00 on an American table. Green doesn’t mean a bigger payout.
What changes is the wheel: one green pocket gives a 2.70% house edge, two give 5.26%.
Lightning Roulette
One to five Lucky Numbers get multipliers of 50x to 500x each round, but only straight-up bets get them. A straight-up that wins without one pays 29:1, and other bets pay as normal.

It works the same on software and live tables. Pick your chip value, then tap the middle of the number. Before betting closes, check the bet panel lists just the one number.
Avoid these
Six Straight-Up Bet Mistakes to Avoid
- Reading 35:1 as the total you get back.It’s £35 profit for every £1, plus your £1 stake back.
- Leaving the chip on a line.A chip on a line or corner becomes a split, corner or street, and pays less.
- Thinking a number is due.Ten misses don’t change the next spin. It’s still 1 in 37 on a European wheel.
- Thinking more numbers means better value.You win more often, but every chip keeps the same house edge.
- Playing American when European is there.Same payout, but the extra 00 nearly doubles the house edge.
- Expecting La Partage to help.The half-back rule only covers even-money bets, not single numbers.
Good to know
Straight-Up Bet FAQs
What is a straight-up bet in roulette?
A bet on one number. You put your chip in the middle of that number’s box, and if the ball lands there, it pays 35:1.
How much does a straight-up pay?
35:1. A winning £10 bet makes £350 profit, and you get your £10 stake back as well, so £360 in total.
Do you get your stake back on a straight-up win?
Yes. The 35:1 is your profit, and your stake comes back on top. A winning £1 chip returns £36.
Is a straight bet the same as a straight-up?
Yes. Straight-up, straight bet and single-number bet all mean one chip on one number, paying 35:1.
Can I place a straight-up bet on 0 or 00?
Yes. Zero is on every wheel, and 00 is on American tables. A straight-up on either pays the same 35:1 as any other number.
Can you bet on every number in roulette?
Yes, but you can’t win. With £1 on all 37 numbers of a European wheel, you stake £37 and get £36 back every spin, so you lose £1 a spin. That £1 is the house edge.
What is the most you can win on one number?
Your table’s maximum bet on a single number times 35. At a table with a £500 limit on one number, the biggest standard win is £17,500, plus your £500 back. Multiplier games like Lightning Roulette can pay more on a Lucky Number.
Can I bet on several single numbers in the same spin?
Yes. Each number gets its own chip and is settled as its own bet. If one wins, that chip returns 36 times its value and the others lose.
Does covering more numbers reduce the house edge?
No. You win more often, but each chip still has the same 2.70% edge on a European wheel, or 5.26% on an American one.
Is a straight-up bet better than a split or corner?
Not on value. They all have the same house edge on a standard wheel. A straight-up wins less often and pays more, so your results swing more.
What does a straight-up pay in Lightning Roulette?
29:1 on a normal win. If your number is a Lucky Number that round, it pays between 50x and 500x instead.
Is my number due if it hasn’t landed for a while?
No. The wheel has no memory, so every spin is a fresh 1 in 37 on a European wheel. A single number goes 100 spins without landing about once in every 15 tries.
