House edge

The house edge is the mathematical advantage that a casino or betting establishment has over players in a game. It represents the average percentage of each bet that the house expects to keep over time. For example, if a game has a house edge of 5%, then, on average, the casino will retain 5% of all money wagered on that game in the long run. Understanding the house edge helps players gauge their chances of winning and manage expectations, but it doesn't predict individual outcomes, which are always subject to chance.
