This is terrible, the RNG should be more like a game rather than using a Game that got created by Giant companies to rigg out peoples money. "The House always wins". Thats no other in this Blackjack version, because the Player always needs to make the first move, so the dealer Wins more rounds with bad cards than the Player. Without some fairness balancing this just feels so unfair.
Best brute force is to start with 150 bet and pray that you have 3-4 good rounds back to back. if not, get bankrupt and start over with new 150€ you start with
