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.
Blackjack is a classic casino card game, also referred to as 21. The object of the game is simple get your hand total to score as close to 21 as possible, without exceeding 21. There's no greater feeling for a player than getting a natural blackjack!
