The player can continue to ask for one additional card at a time (by saying “Hit”) until s/he decides to stop, or until s/he goes bust. The goal is to get closer to 21 than the dealer, without going bust. So the player is asked if s/he wants another card or not, in an effort to get closer to 21 (without going over also known as going “bust”).

For example, if the player has a Three of Hearts and a King of Spades, the value of the hand is 3+10 = 13.Īlthough we do not know the value of the dealer’s hand at the beginning of the round (because one of the dealer’s cards is face down), we do know that in our version of the game neither the dealer nor the player can possibly have a hand that sums to 21 after the first four cards have been dealt. The value of each hand is determined by summing the value of the face-up cards in the hand together. The dealer then deals a second card (face up) to the player, and a second card (face DOWN) to the dealer. In our version of the game, the Ace always has a value of 1.Īt the beginning of a round, the dealer deals a card (face up) to the player, and a card (face up) to the dealer. If is it a Jack, Queen, or King, its value is 10. two of spades have a value of 2, ten of hearts has a value of 10). If the rank is numeric, the value is its rank. In 21, each card is assigned a value based on rank alone.
