The house edge in roulette is the built-in advantage that ensures the casino always wins over time. This small percentage might seem harmless, but it’s the core reason why no betting system can beat roulette in the long run. Below you’ll learn how the house edge works, how it’s calculated, and which versions of roulette give players the best odds.
What Is the House Edge?
The house edge represents the average percentage of each bet that the casino expects to keep. For example, a 2.70% house edge means that, over thousands of spins, the casino keeps €2.70 out of every €100 wagered.
Roulette has one of the lowest house edges among casino games — but it varies depending on the version you play.

How to Reduce the House Edge When Playing
Tekst: 1️⃣ Choose European or French tables – always avoid double-zero wheels. 2️⃣ Play at casinos with La Partage or En Prison – halves the edge on even bets. 3️⃣ Stick to even-money bets (Red/Black, Odd/Even) – they benefit most from French rules. 4️⃣ Ignore “hot/cold” myths – they don’t influence the math. 5️⃣ Manage your bankroll – strategy doesn’t change the edge, but discipline extends your playtime.
