Unfortunately, it’s highly unlikely for any kind of card counting strategy to work if you’re playing blackjack online. It’s easy to keep track of cards during a game of online blackjack, however, there’s no way of knowing if the deck has been reshuffled or not. Essentially, every new hand dealt out by a computer programme has been randomly generated and randomly selected from a full deck. Every hand that is dealt comes from a fresh card deck, making card counting nigh on impossible. There is, however, a reason to keep your card counting strategy alive, and that’s because it’s good practise for when you get to play a live game. There is one exception to this rule, and that’s live online casinos, where you can see the dealer and the cards and when the deck is reshuffled.
