What is the house edge?
The house edge is the percentage of every wager a game keeps on average. Multiply it by how much you bet and how fast, and you get your expected loss over time — a reminder that volume against a negative edge grinds a bankroll down. Sharp betting is about finding a positive edge, not a negative one.
