Unfortunately, online casinos don’t display their house edge anywhere. But you can always check the list of RTP rates of all games. If you can’t find it on a casino site, ask your customer support manager. Or you can manually check the RTP of a game you want to play in its game rules. The opposite of the RTP rate will be the house edge. For example, if a game’s RTP is 95%, then 5% is the house edge of that game.
