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%
Even-Money 18 1:1 18/37 ≈ 48.65% 2.70% (1.35% on Fr. with La Partage)
French advantage: Even-money with La Partage halves losses on 0 → ~1.35% edge on those bets.

“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
EV snapshot (per £100 over time):
Even-money on European ≈ −£2.70 per £100 turned; on French (La Partage) ≈ −£1.35 on even-money.
Reality check:
Low-probability bets (e.g., Straight/Split) can miss for long stretches. Bankroll & limits matter more than “systems.”

Common Mistakes That Hurt Your Odds

Chasing losses: doubling without a hard stop-loss.
Wrong wheel: playing 00 American out of habit (higher edge).
Ignoring rules: skipping La Partage when available.
Over-coverage: overlapping inside bets that cancel gains.
Too fast: Speed tables + big chips = tilt risk. Keep units small.

Glossary — Terms in Plain English

House edge: Long-run average the casino keeps from each £1 wagered.
EV (expected value): Average win/loss per spin for a given bet & wheel.
La Partage: On 0, even-money bets lose half instead of all (French).
RTP: 100% − house edge (long-run % returned to players).
Variance: How swingy results are. Straights are high variance.

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.
