Every casino game, from the flashing lights of the slot machines to the felt of the blackjack table, casino is built on a mathematical foundation. This principle, the house advantage, is fundamental to how casinos operate.
The Casino's Built-in Profit
The house edge is the long-term mathematical advantage that the casino has over the player in any given game. It is usually expressed as a percentage. A 2% house edge implies an average casino profit of $2 for every $100 bet.
It's crucial to understand that this is a long-term average. Short-term variance allows for huge wins, which is the allure of the casino. Yet, the law of large numbers guarantees the casino will profit in the end.
Which Games Offer the Best Odds?
Different games have vastly different house edges. Choosing games with a lower house edge can give you a better chance of winning in the short term and will make your bankroll last longer.
