Counting cards in online Blackjack is much harder than in land-based casinos due to the way online games are structured. In online RNG games, cards are reshuffled after every hand or several hands, making it impossible to track card distribution. Even in live dealer games, continuous shuffling or the use of multiple decks complicates card counting. In contrast, land-based casinos allow players to observe the shuffle and track deck penetration, creating a more favorable environment for card counters.
