In case you missed the previous release, this is a BlackJack game, but not your ordinary BlackJack game. This one "aims to help you beat the casino by helping the practice of card counting and basic strategy."
Basically it helps you count the cards that have already been played. This will help you increase your chances of beating the casino with each round, as you have the advantage of knowing what cards still remain in the deck. Simple. Ingenious. Great practice before I go to a casino to burn my money.
