How Many Decks Does Vegas Use for Blackjack?

In the early days of Vegas blackjack, casinos used a single deck of cards. This made it easy for card counters to keep track of which cards had been played and which remained in the deck, giving them a significant advantage over the house.

In response, casinos began using multiple decks, making it much harder for card counters to keep track of which cards had been played.
