The house edge is the mathematical advantage the casino holds over every bet. A 2.7% house edge on European roulette means that for every £100 wagered, the casino expects to keep £2.70 on average. Over thousands of rounds, real results converge toward this expectation — though short-term variance can produce big wins or losses.
Blackjack with basic strategy offers one of the lowest house edges in any casino at around 0.5%, while American roulette (with two zeros) nearly doubles the European version's edge. Slots vary enormously by RTP — always check the paytable before playing. Understanding house edge is the most important step in managing your casino bankroll responsibly.
