House Edge

House edge is the mathematical advantage a casino holds over players on each game, expressed as a percentage of each wager the operator expects to retain over time.

What it means in practice

House edge is the built-in statistical advantage that ensures a casino generates revenue over time. It represents the percentage of every wager that the operator expects to keep on average. A game with a 5% house edge means the casino retains $5 for every $100 wagered over a large sample size. This is the foundation of GGR (Gross Gaming Revenue) - the metric that drives RevShare calculations in affiliate programs.

Different games carry different house edges. Slots typically range from 2% to 10%, blackjack can be under 1% with optimal play, and roulette sits around 2.7% (European) or 5.26% (American). For affiliates operating under RevShare or hybrid commission deals, the house edge of games their referred players prefer directly impacts commission revenue. Players on low-edge games generate less GGR per dollar wagered.

House edge is related to but distinct from Slot RTP (Return to Player). RTP is the complement of house edge: a slot with 96% RTP has a 4% house edge. Understanding this relationship helps affiliates evaluate which casino products and game portfolios will generate the most sustainable NGR (Net Gaming Revenue) for their traffic.
