Play Blackjack like you would at the casino. Get a total of 21 (or as close as you can without going over) to beat the dealer. If the dealer gets 21, they win!
The cards 2 through 10 are worth their face value. Kings, queens, and jacks are each worth 10, and aces may be used as either 1 or 11. The object for the player is to draw cards totaling closer to 21, without going over, than the dealer's cards. The best total of all is a two-card 21, or a blackjack.
