Welcome to this comprehensive guide on roulette, where I’ll share my insights as a casino owner with over 15 years of experience. This guide is designed to help both beginners and experienced players understand the game better, make informed decisions, and avoid common pitfalls, tailored for an international audience.
Roulette Basics
Roulette is a game of chance played with a spinning wheel and a ball. The wheel is divided into numbered pockets, and the ball lands in one of these, determining the outcome of the bets. There are two main versions: European and American, each with different setups.
- European Roulette: Has 37 pockets, numbered 0 to 36, with alternating red and black colors for 1 to 36, and 0 is green. The house edge is about 2.7%.
- American Roulette: Has 38 pockets, numbered 0, 00, and 1 to 36, with 0 and 00 green. The house edge is higher at 5.26%.
From my experience, players who choose European roulette have better odds due to the lower house edge, so always opt for it if available.

Common Mistakes and Tips
Beginners often make mistakes that can lead to losses. Here are some, with tips to improve:
- Mistake: Not understanding American vs. European roulette, often playing American with higher house edge.
Tip: Always choose European roulette for better odds. - Mistake: Making random bets without knowing odds, like betting on inside bets with low win probability.
Tip: Understand payouts and probabilities before betting, favoring outside bets for better chances. - Mistake: Chasing losses, increasing bets to recover, leading to bigger losses.
Tip: Set a budget and stick to it, avoiding emotional decisions. - Mistake: Believing in “hot” or “cold” numbers, thinking past results affect future spins.
Tip: Each spin is independent; there’s no pattern to predict. - Mistake: Not knowing when to quit, playing until losing heavily.
Tip: Set win and loss limits, and walk away when reached.
From my casino, I recall a player betting on 17 every Friday, winning occasionally but losing more, showing the risk of luck-based play. Another stuck to outside bets, often leaving with small profits, highlighting disciplined strategy.
