How Online Casinos Make Money from Games
Online casinos generate revenue from games through the house edge. The house edge is achieved through the combination of the return-to-player (RTP) rate and the volatility of the game. Slot games, for example, have a high house edge due to their high volatility and low RTP rate. Table games, on the other hand, have a lower house edge due to their lower volatility and higher RTP rate.
The house edge for slot games can range from 5-15%, while table games have a lower house edge of 1-5%. This means that for every $100 bet on a slot game, the casino can expect to win $5-15 in the long run. For table games, the casino can expect to win $1-5 for every $100 bet.
Slot Games

Table Games
Table games, such as blackjack and roulette, have a lower house edge than slot games. The house edge for table games can range from 1-5%. The house edge is achieved through the rules of the game, such as the number of decks used in blackjack or the presence of a zero in roulette.
