It represents the mathematical advantage built into the rules of the game, ensuring that over time, the casino will make a profit. The house edge varies from game to game, with some having a higher percentage, which means players are more likely to lose in the long run. It is calculated based on the difference between the true odds of winning and the payout offered by the casino.
House Edge Example
For example, in European Roulette, the house edge is about 2.7%. This means that for every $100 bet, the casino expects to make $2.70 over time.
