Blackjack is a card game where the object is to get a total as close to 21 as possible without going over 21. Each player is dealt two cards, with values ranging from 2 to 10, J, Q, K being 10, and A being either 1 or 11. Players can choose to "Hit" (draw more cards) or "Stand" (stand). If the total goes over 21, they lose. After the player completes their turn, the dealer turns over a second card and must "hit" if it is under 17. The player wins if the total is higher than the dealer without going over 21.
