The player can hit, stand, double down, or split their hand.The value of the cards is determined by their face value, with numbered cards worth their numerical value, face cards worth 10, and an ace worth either 1 or 11.Here are some of the key things to keep in mind when playing blackjack: If the player and dealer have the same hand value, it is a push and the player’s bet is returned. If the dealer busts, all remaining players win. The dealer must hit on a hand of 16 or less and stand on a hand of 17 or more.
