Basic Play\n\n If your cards total higher than the dealer's cards without going over 21, you win. If your hand goes over 21, you "bust" and lose your bet. If the dealer busts, you win. It's an interesting feature not only of blackjack but of all casino games that the house or casino  always has the advantage.
Introduction: How to Play 21/Blackjack\n\n The goal of 21 is to amount your card values as near to 21 as possible without exceeding or 'busting' it. Moreover, you have to beat whatever hand both the dealer and other players have drawn; if they have 20 and you have 19, you lose the hand.
