The house edge for online blackjack is between 0.4 and 0.5 percent. This means that the RTP percentage on the table game is greater than 99%. If you deposit $100, the table will pay out $99 on average. When compared to other games such as slots, this is by far a higher RTP. This is, of course, assuming that you’re playing regular online blackjack. If you can understand the game, the rules and some strategy, you’ll have a good chance of winning.
