What Is a Straight-Up Bet?
A Straight-Up bet is a wager on exactly one number (0–36 on European/French, 00 also on American). If the ball lands on that number, the bet pays 35:1.
- ✔️ Biggest standard payout in roulette
- ⚠️ Lowest hit chance: 1/37 EU/French, 1/38 American
- 🎯 Great for shot-taking and multiplier variants (e.g., Lightning Roulette)

How to Place a Straight-Up Bet
- Open a table (prefer European or French for value; avoid American if possible).
- Select your chip value and drop it on the centre of your number square (0/00 allowed).
- Spin (RNG) or wait for the dealer (live). If it lands on your number → 35:1 payout.
Straight-Up Odds, House Edge & Expected Value (EV)
The payout (35:1) is the same on all wheels, but the probability isn’t — the extra 00 on American increases the house edge.
| Variant | Hit chance | House edge | Payout | EV per £1 |
|---|---|---|---|---|
| European (single zero) | 1/37 = 2.70% | 2.70% | 35:1 | −£0.027 (−2.70%) |
| French (La Partage helps outside only) | 1/37 = 2.70% | 2.70%* | 35:1 | −£0.027 (−2.70%) |
| American (double zero) | 1/38 = 2.63% | 5.26% | 35:1 | −£0.0526 (−5.26%) |
EV (per £1) = 35×p − (1−p). For EU: 35/37 − 36/37 = −1/37 ≈ −2.70%.
How Often Does a Straight-Up Hit?
The chance of at least one hit in n spins is 1 − (1−p)n, where p is 1/37 (EU) or 1/38 (US).
Racetrack & Neighbours — A Smarter Way to Aim Straight-Ups
On many live/EU tables, you get a racetrack view of the wheel for quick neighbours and French call bets. This is perfect when you want a Straight-Up plus adjacent coverage.
Neighbours (Voisins proches)
“Neighbours of N” places one Straight-Up on your number and identical chips on its adjacent numbers on the wheel (usually ±2). Example: “17 with 2 neighbours” = 5 Straight-Ups total.
- Use case: hunt a favourite while softening misses
- Cost: 5× your base chip (for ±2)
French Call Bets (single-zero wheels)
- Voisins du Zéro (17 numbers around 0)
- Tiers du Cylindre (12 numbers opposite 0)
- Orphelins (8 “orphans” split across two sectors)
Add one or two Straight-Ups within the sector for a shot at spikes while most misses land on covered splits/corners.
Live Multipliers Math — Straight-Ups in Lightning/Quantum
Multiplier tables (e.g., Lightning Roulette, Playtech Quantum) reduce non-multiplied Straight-Ups to around 29:1 but randomly boost selected numbers (e.g., 50x–500x). Expected value is balanced in the paytable, but variance soars.
| Outcome type | Example payout | Notes |
|---|---|---|
| Non-multiplied hit | ~29:1 | Lower base payout funds the multipliers |
| Multiplied hit | 50x–500x | Only on Straight-Ups; huge spikes |
| Outside bets | Usual 1:1 / 2:1 | Multipliers typically don’t apply |
Smart Ways to Use Straight-Ups (Combinations)
“24 + 8” Coverage
Bet two dozens (1–12 & 13–24) plus 8 Straight-Ups on 25–36. Dozens aim for breakeven; a Straight-Up landing gives a big net win.
| Bet | Covers | Outcome |
|---|---|---|
| Dozen 1 & 2 | 1–24 (24 numbers) | Usually breakeven when they hit |
| 8 Straight-Ups | 25–36 | Big profit if one lands |
High chip count (10–12 units). Manage limits carefully.
11-Number “Hot-Zone”
Pick last winning number and 10 neighbours you like. Bet 1 unit each across 11 numbers.
- Hit returns 35, −10 on misses → +25 net
- Misses accumulate quickly; cap session loss
Outside + Straight-Ups
Pair a small outside bet (e.g., Red) with 1–3 Straight-Ups you’re “hunting”. Outside stabilises, Straight-Ups provide the spikes.
Bonus play: Some casinos flag board-coverage patterns during wagering. Check terms on our roulette bonuses page.
Bankroll Management for Straight-Ups
- Unit size: Keep base unit ≤ 2–5% of bankroll (lower is safer).
- Stop-loss: Pre-set a hard loss cap (e.g., 10–20 units) and walk away.
- Stop-win: After a 35:1 hit, bank a chunk (50–70%) before continuing.
- Table limits: Check min/max and inside bet caps on live tables.
- Wheel choice: Prefer EU/French; avoid American where possible.

Where Straight-Ups Shine (by Game Type)
European Roulette
Best baseline. Lower edge (2.70%). Great for hunting a favourite number with occasional spikes.
French Roulette
La Partage doesn’t change Straight-Up EV but helps your outside cover. Good for “outside + singles” blends.
Lightning Roulette
Straight-Ups can be supercharged by 50x–500x multipliers (non-multiplied hits pay ~29:1). Expect high variance.
American Roulette
Playable, but edge is 5.26%. Consider only if EU/French unavailable or for casual fun.

Straight-Up Bet — FAQs
Is the Straight-Up bet “worth it”?
It’s a high-variance shot with the biggest standard payout. Great for spikes or multiplier games; not ideal for slow, steady grinding.
Can I place Straight-Ups on live roulette?
Yes. Available on all live/RNG tables, including 0 (and 00 on American).
What’s the hit rate?
EU/French: 1/37 (2.70%). American: 1/38 (2.63%). Use the calculator above to estimate hits across multiple spins.
Do any rules improve Straight-Up EV?
Not directly. La Partage helps even-money bets, not Straight-Ups. Choose EU/French wheels to reduce overall edge.
Best way to use Straight-Ups?
Blend small Straight-Ups with outside cover, keep units small, cap losses, and bank a portion after big hits.
