Understanding Roulette Odds

💡 Key Concepts

House Edge

The casino's mathematical advantage over players. European roulette has a lower house edge (2.7%) than American (5.26%).

True Odds vs. Payout Odds

True odds reflect the actual probability, while payout odds are what the casino pays. The difference creates the house edge.

🎯 Best Bets

European vs American

Always choose European roulette when possible - the single zero gives you better odds on every bet.
