You and fellow players are dealt two cards each whilst the dealer is dealt one face up. If your first 2 cards add up to 21 (an Ace and a card valued 10), that's Blackjack! If they have any other total, decide whether you wish to 'draw' or 'stay'. You can continue to draw cards until you are happy with your hand.
After all players are satisfied with their hands the dealer will turn his or her down card face up and stand or draw as necessary. The dealer stands on 17 or higher. All winning bets are paid even money (1 to 1), except for Blackjack, which pays you one-and-a-half times your bet or 3 to 2. basic game of Blackjack.
