European Roulette — Real Odds & Payout Calculator
Roulette has no winning system — every spin is independent and the house edge sits at a fixed 2.70% (European, single zero) no matter which number or bet you pick. So the wheel below is just for fun, and the calculator tells you exactly what any bet really pays.
European vs American Roulette — Why It Matters
European roulette has 37 pockets (0–36) and a house edge of 2.70%. American roulette adds a double-zero (00), raising the house edge to 5.26% — nearly double. Always choose European when you have the option. Our featured casino offers both, and most live tables default to the European wheel.
Inside Bets vs Outside Bets
Inside bets cover specific numbers or small groups. Higher payout ratios (up to 35:1 straight-up), lower win frequency. Best for short sessions with a big-win target.
Outside bets cover large groups: Red/Black, Odd/Even, 1–18/19–36, Dozens, Columns. Lower payouts (1:1 or 2:1), much higher win frequency. Best for longer sessions and bankroll management.
The Truth About Betting Systems
Martingale, Fibonacci, D'Alembert — no betting system changes the 2.70% house edge. They restructure risk: the Martingale reduces loss frequency but increases the severity of a bad streak. Use them for entertainment structure, not as a profit strategy.
