How Card Counting Works and Why Casinos Dislike It

Card counting is a strategic technique used by players to gain an advantage over the casino in blackjack. Unlike pure luck-based games, card counting involves tracking the ratio of high to low cards remaining in the deck, allowing players to make more informed betting decisions. Casinos, however, view this practice as a threat to their profitability because it shifts the odds away from the house edge.

At its core, card counting requires a player to assign values to cards as they are dealt—typically +1 for low cards (2-6), 0 for neutral cards (7-9), and -1 for high cards (10-Ace). By keeping a running count and adjusting bets accordingly, the player can increase wagers when the deck is favorable. Casinos employ various countermeasures, from shuffling decks more frequently to banning suspected counters, in order to maintain their advantage and protect their revenue.
