<Li> Let the dealer draw additional cards until their hand exceeds 21 . </Li> <P> Players are each dealt two cards, face up or down depending on the casino and the table at which you sit . In the U.S., the dealer is also dealt two cards, normally one up (exposed) and one down hidden). In most other countries, the dealer receives one card face up . The value of cards two through ten is their pip value (2 through 10). Face cards (Jack, Queen, and King) are all worth ten . Aces can be worth one or eleven . A hand's value is the sum of the card values . Players are allowed to draw additional cards to improve their hands . A hand with an ace valued as 11 is called "soft", meaning that the hand will not bust by taking an additional card; the value of the ace will become one to prevent the hand from exceeding 21 . Otherwise, the hand is "hard". </P> <P> Once all the players have completed their hands, it is the dealer's turn . The dealer hand will not be completed if all players have either busted or received Blackjacks . The dealer then reveals the hidden card and must hit until the cards total 17 or more points . (At most tables the dealer also hits on a "soft" 17, i.e. a hand containing an ace and one or more other cards totaling six .) Players win by not busting and having a total higher than the dealer, or not busting and having the dealer bust, or getting a blackjack without the dealer getting a blackjack . If the player and dealer have the same total (not counting blackjacks), this is called a "push", and the player typically does not win or lose money on that hand . Otherwise, the dealer wins . </P> <P> Blackjack has many rule variations . Since the 1960s, blackjack has been a high - profile target of advantage players, particularly card counters, who track the profile of cards that have been dealt and adapt their wagers and playing strategies accordingly . </P>
