If you are a regular casino player, then surely you have read or heard about the house edge. It’s a truism in the gambling industry- you can’t beat the house over the long term. Casino operators still run a business, and they make sure online casinos remain profitable. This is possible thanks to the concept of a house edge. Simply put, the online casino house edge refers to the theoretical advantage of the casino in a specific game.

Let’s use the popular online slot as an example to explain this concept. Online slots have Return to Player (RTP) percentage, and it normally ranges from 95 to 97%. It describes the percentage of the amount that a slot game theoretically returns to players over the long term in the form of winnings. A game with a 97% RTP means that it will theoretically return 97% of all wagered money to players in the form of winnings. Simply put, for every $100 wagered, the games pay out $97 over the long term. 

The house edge is simply the opposite of the RTP. Going back to the slot machine with 97% RTP, its house edge is 3%, which acts as the casino’s advantage. It means that the lower the house edge, the smaller the share of the operator. To improve your chances of winning, look for the games with the lowest house edge.
