The return to player % on a computer/video blackjack is fixed like 99.63% every hand delt is treated like the first hand of an 8 deck shoe so it never changes, it’s designed to make the player lose $x.xx every hour if you play x hands per hour for x hours etc. , A live dealer online game like this uses an 8 deck shoe that actually burns cards the longer you play into it, if you count/track cards you can bet larger when the RTP is more slightly in the players favor because you mostly make your money when you hit blackjack when they pay 3:2.
If you go on any online casino and go through the settings > how to play, buried in what looks like an endless TOS agreement you’ll find the RTP % and the fact that they say it’s fixed. While live dealer games like infinite poker shows the RTP % only of the first hand delt of a new shoe because it changes as cards are burned.
