Key Facts
• European roulette has one zero (0) — house edge 2.70%. American roulette adds a double zero (00), raising the edge to 5.26%. Always choose European.
• All standard bets share the exact same 2.70% house edge — higher payouts come with lower win probability, but expected value is identical.
• La Partage and En Prison are French-rule variants that halve the edge on even-money bets to 1.35% — the best roulette rules available.
• A straight-up bet on 1 number has a 1/37 ≈ 2.7% chance of winning, paying 35:1 (true odds would be 36:1 — the gap is the house edge).
• There is no bet that beats the house edge over time — strategy is about minimising the edge, not eliminating it.
