Roulette is one of the easiest casino games to learn and one of the best to understand mathematically. Here's everything a beginner needs.

European vs American roulette
European roulette has a single zero (37 pockets), so the house edge is about 2.7%. American roulette adds a double zero (38 pockets), which raises the edge to about 5.26%. Choose European whenever you can.

Why systems don't beat the wheel
Doubling your stake after a loss (the Martingale) feels safe until a long losing run hits your budget or the table limit. Every spin has the same odds, and no betting pattern changes the house edge.
