The house edge is the mathematical advantage that a casino has over players on every bet, expressed as a percentage. It is the inverse of RTP — a game with 96% RTP has a 4% house edge. This built-in advantage ensures casinos are profitable over time, regardless of individual player outcomes.
Every casino game is designed with a house edge that guarantees the casino will profit in the long run. The house edge varies significantly between games: blackjack with basic strategy has a 0.5% edge, baccarat banker bet is 1.06%, European roulette is 2.7%, American roulette is 5.26%, and some slot games can have edges above 8%. Understanding the house edge helps you make informed choices about which games to play. Lower house edge means your bankroll lasts longer on average. At sweepstakes casinos, the house edge works the same way — it is applied to Sweeps Coin wagers. Provably fair games at crypto casinos allow you to independently verify that the stated house edge is accurate.
European roulette has a house edge of 2.7%. If you bet $10 on red 100 times ($1,000 total wagered), the casino expects to keep $27 on average. You would expect to have $973 remaining.
