How do online casinos make money?

A. Unlike online poker rooms, which take a flat percentage from each pot for hosting the games, online casinos offer games which are slightly in their advantage.

For example, if you played Blackjack Surrender at Casino Tropez, the casino advantage is a miniscule amount, less than 0.4%. This is a tiny edge for the casino, but over millions of hands, they can make enough to justify their expenses in buying the software and setting up their online casino.

All casino games have different House Advantage odds, with some games being more advantage to the house than others. A shrewd gambler might ask the online casino support team about the house advantage for particular games he/she wished to play.
