What Is the House Edge?
In every casino game, the odds are stacked—just slightly—in favor of the house. This built-in advantage, known as the house edge, ensures the casino makes a profit over time. For players, understanding house edge is the key to making smarter bets and choosing games that give them the best chance of winning.
