How Many Decks of Cards Do Casinos Use in Blackjack?

Most casinos use between one and eight decks of cards in blackjack. The specific number of decks used depends on the casino and the specific game being played.

For example, some casinos use multiple decks in order to discourage card counting, while others only use a single deck in order to speed up play. The number of decks used also affects the house edge in blackjack; the more decks, the higher the edge.
