Roulette is one of the few casino games where player decisions directly influence risk and potential outcomes. While the rules are simple, the structure behind roulette—especially house edge and bet types—determines how the game performs over time.
The key difference between roulette variants lies in the number of zeros. This single detail changes the house edge and long-term expectations significantly.
Before choosing a table, it’s important to understand how odds and payouts work. The Casino RTP Guide explains expected returns, while the Casino Game Types Guide gives a broader overview of table games.

Roulette is a probability-based table game built around a spinning wheel and fixed betting odds. Unlike slots, where outcomes are entirely automated, roulette allows players to choose how they distribute risk across different bet types.

|---|---|---|
| European Roulette | 1 (0) | ~2.7% |
| American Roulette | 2 (0, 00) | ~5.26% |
| French Roulette | 1 (0) + special rules | ~1.35% (with La Partage) |
European roulette is generally preferred because it offers a lower house edge compared to American tables.
