There is a hole in the blackjack card because it is made of plastic. Blackjack is a game of chance that is played with a deck of 52 cards. The object of the game is to score as close to 21 as possible. A player’s hand consists of two cards, face down.
The player’s goal is to turn over at least one card that adds up to 21. If the player turns over two cards that add up to 21, they are awarded a “blackjack” and the dealer loses the pot. A hole in a card allows the player to win even if they get two cards that add up to 20.
