In Blackjack you and the dealer start with two cards. Yours will be face up and the casino dealer will have one face up and one face down. You are allowed to hit until you are comfortable with your number or until you bust. This is also the time when you decide to double, take insurance, or split a pair. After that time it is then the casino dealer's turn. They can hit until they have beat you or until they bust. You then take your earnings, or not, based on who had the best hand.
