Blackjack is an exciting and accessible card game that is played all over the world. It is also known as "21", because it involves the player trying to create a hand that is worth exactly 21. A player plays against the dealer, and if their hand is worth more than 21 they are bust and lose the round. In order to win the player must beat the dealerās hand, but if the dealer has 21 or a hand worth more than 21, the player wins. The main goal of the game is to use the basic strategy to beat the dealer.
