Blackjack is a card game that uses a deck of 52 cards. The number of decks used in blackjack is determined by the variation of blackjack being played. There are single-deck blackjack variations where only one deck of cards is used, and there are multiple-deck variations where four, six, or eight decks of cards are used. 

There are many reasons why casinos opt to use multiple decks, and they include reducing the shuffling time between rounds, increasing the house edge for the casino as multiple deck games have a higher house edge than single deck games, and reducing the effectiveness of card counting blackjack strategies by professionals.

The number of decks used in a blackjack game is determined by the variation and the casino. There is no set number of decks that can be used, and players can check the number of decks being used before they start playing.
