Blackjack is played with a conventional deck of 52 playing cards and suits don't matter. 2 through 10 count at face value, i.e. a 2 counts as two, a 9 counts as nine. Face cards (J,Q,K) count as 10. Ace can count as a 1 or an 11 depending on which value helps the hand the most.
All cards are at face value, except for the King, Queen and Jack which count as 10.
