Understand roulette odds, compare wheel types, and analyze popular betting systems for this classic game.
European vs American Roulette
The wheel type dramatically affects your odds. Always choose European (single zero) over American (double zero) when possible.
- European Roulette: 2.70% house edge (37 numbers)
- American Roulette: 5.26% house edge (38 numbers)
- French Roulette: 1.35% on even money bets (La Partage rule)
Betting Systems Analysis
Popular betting systems like Martingale, D'Alembert, and Fibonacci cannot overcome the house edge long-term.
System Reality
System Reality
No betting system can change the mathematical expectation of roulette. They may alter variance but cannot eliminate the house edge.
Best Roulette Bets
All roulette bets (except the basket bet in American roulette) have the same house edge, so bet selection is about preference and variance.
- Even Money Bets: Lower variance, frequent small wins
- Single Numbers: High variance, rare large wins (35:1)
- Dozen/Column Bets: Medium variance (2:1 payouts)
