Payouts & Win Probabilities (European Wheel)
| Bet Type | Numbers | Payout | Win Chance | House Edge |
|---|---|---|---|---|
| Straight-Up | 1 | 35:1 | 1/37 ≈ 2.70% | 2.70% |
| Split | 2 | 17:1 | 2/37 ≈ 5.41% | 2.70% |
| Street | 3 | 11:1 | 3/37 ≈ 8.11% | 2.70% |
| Corner | 4 | 8:1 | 4/37 ≈ 10.81% | 2.70% |
| Six Line | 6 | 5:1 | 6/37 ≈ 16.22% | 2.70% |
| Dozen / Column | 12 | 2:1 | 12/37 ≈ 32.43% | 2.70% |

“Perfect Maths” vs Real Table Payouts (European)
The gap (“Shortfall”) is the built-in house edge on inside bets.
| Bet | If paid by the wheel* | Actual table pays | Shortfall per £1 |
|---|---|---|---|
| Straight (1) | 36:1 | 35:1 | −£1 |
| Split (2) | 18:1 | 17:1 | −£1 |
| Street (3) | 12:1 | 11:1 | −£1 |
| Corner (4) | 9:1 | 8:1 | −£1 |
| Six Line (6) | 6:1 | 5:1 | −£1 |
Example: Bet £1 straight-up. “Perfect” would pay £36. Tables pay £35. That missing £1 is the edge spread over all spins.
*European has 37 pockets, so a 1-number bet is 1/37 — to pay perfectly you’d need 36:1.
What to Expect Over 10 / 50 / 100 Spins
European wheel; expectations, not promises — real sessions swing around these.
| Bet | Win Chance (1 spin) | Expected Wins (10) | (50) | (100) |
|---|---|---|---|---|
| Even-Money | 48.65% | ~4.9 | ~24.3 | ~48.7 |
| Dozen/Column | 32.43% | ~3.2 | ~16.2 | ~32.4 |
| Straight-Up | 2.70% | ~0.3 | ~1.4 | ~2.7 |
Even-money on European ≈ −£2.70 per £100 turned; on French (La Partage) ≈ −£1.35 on even-money.
Low-probability bets (e.g., Straight/Split) can miss for long stretches. Bankroll & limits matter more than “systems.”

Roulette Betting Strategies
Roulette Odds — FAQs
What are the best odds in roulette?
Even-money bets on a French single-zero wheel with La Partage (~1.35% edge) offer the best long-run value.
Do multipliers change my odds?
Base probabilities are the same, but non-multiplied straight-ups pay less (≈29:1) to fund multipliers → higher variance.
Is American (00) really that bad?
Yes — the extra 00 lifts the edge to ~5.26% on all bets. For value, pick European or French.
How big should my chip size be?
Keep each bet ≤2–5% of your session bankroll. Smaller chips = longer runway.
Does La Partage help inside bets?
No, it only helps even-money bets. Inside payouts don’t change.
