What is House Edge?
The house edge is the mathematical advantage that a casino maintains over players in any given game. It represents the percentage of each bet that the casino expects to win over time. Understanding house edge is fundamental to making informed decisions about casino gaming.
Every casino game has a built-in statistical advantage favoring the house. This advantage varies significantly across different games. For example, blackjack typically has a house edge between 0.5% and 2%, while slot machines can range from 2% to 15% depending on the machine and jurisdiction. Roulette sits at 2.7% for European wheels and 5.26% for American wheels due to the green pocket structure.
The house edge is not something that affects every single hand or spin equally. Rather, it describes the long-term mathematical expectation. Over thousands of hands, the casino's theoretical profit margin becomes apparent. This is why understanding these percentages helps players set realistic expectations and make strategic choices about which games to play.
