Unfortunately not. Unlike in land-based casinos, where card counting techniques experienced a massive surge before they were made illegal, online blackjack games make use of a mechanism known as Continuous Shuffle Machines, which is responsible for shuffling card decks throughout gameplay. This software makes it highly tricky if not virtually impossible to employ card counting strategies, since it is much faster than a regular human dealer. In our opinion, there are far more superior blackjack strategies to choose from rather than resorting to card counting.
