Blackjack is a popular casino card game that is played with one or more decks of standard playing cards. The objective of the game is to have a hand value of 21 or as close to 21 as possible without going over 21. Here are the basic rules for playing Blackjack:

The game begins with each player placing their bet on the table.

The dealer then deals two cards to each player face up, and two cards to themselves, one face up and one face down.Players then have the option to "hit" (take another card) or "stand" (keep their current hand).

The value of each card is determined by its number, with face cards (King, Queen, Jack) worth 10 and Aces worth either 1 or 11, depending on which value would be more beneficial for the player.
