The answer to this question is not as clear-cut as one would think. In fact, many casinos use more than one deck of cards for blackjack.
This is because the game of blackjack can be played with a variety of different decks, and each deck has its own set of rules.
Some casinos use only one deck of cards for blackjack. This is the most common type of blackjack, and it is also the simplest. This type of blackjack is usually played with 52 cards, including two jokers.
The dealer starts by placing a single card face up on the table, and then everyone else in the game must either draw or place a bet according to the rules of blackjack. If a player has a better hand than the dealer, he or she can win the hand by taking all of the dealer’s chips.
Some casinos use two different decks of cards for blackjack. The first deck is used as the basic or foundation deck, and it has standard playing rules. The second deck is used as the wild card deck, and it has special playing rules that are different from those of the foundation deck.
For example, in some casinos, any card can be used as a wild card, while in others only certain cards can be used as wild cards. When a player plays blackjack with a two-deck format, it is important to remember which deck contains which playing rules.
Many casinos also use a three- or four-deck format for blackjack. In this type of game, there are usually three or four different decks of cards that are used simultaneously.
This allows players to have more opportunities to win hands, since there are more ways for them to get ahead in the game.
