Abstract

A playing card deck for playing blackjack or casino twenty-one. The cards preferably have diagonally opposing primary and secondary corners. All cards in the deck have indicia or markings at the primary corners which indicate the nature of the card (suit and card type). The deck has two groupings of cards. The secondary corners of the first group do not indicate the specific nature or count of the card. The secondary corners of the second group, such as aces, have secondary indicia. This allows a dealer to selectively peek at the secondary corner of his face-down card to determine whether a blackjack hand exists. If blackjack does not exist, then the dealer does not know the face-down card and cheating or unintentional disclosure is prevented.
