House Edge

The casino's inherent mathematical advantage in any given game, typically expressed as a percentage of a player's bet.

The House Edge is the long-term average profit that the casino is expected to make from a game. It is the inverse of the RTP (Return to Player). If a game has an RTP of 96%, its house edge is 4%.

This means that for every £100 wagered on that game, the casino expects to retain £4 as profit over a statistically significant number of plays. The house edge is not a measure of how much a player will lose in a single session but an immutable mathematical reality that guarantees the casino's long-term profitability. Players can mitigate its effect by choosing games with a lower house edge (higher RTP).

House Edge = 100% - RTP

FAQs

Is it possible to beat the house edge?<br>In the short term, yes, due to statistical variance (luck). In the long term, the house edge is a mathematical certainty. The only exception is through advantage play like card counting in Blackjack, which is not possible in online games governed by an RNG.
