  • Patent number: 4170358
    Abstract: A pack of playing cards comprises forty eight split-value cards, the front face of each of which is divided into two visually distinctive zones by means of a diagonal dividing line. Each of the visually distinctive zones represents a different playing card suit-value combination, the arrangement being such that, through the forty eight split-value cards, there is a first zone representing each of the card values ace through three of each of the four suits clubs, diamonds, hearts and spades, and similarly there is a card with the second visually distinctive zone representing each of the same forty eight card suit-value combinations. There is no coupling of similar card-values on the same card of the forty eight split-value cards. The pack is completed with four deuce cards, each having two visually distinctive zones, but both of the zones representing the deuce of the same suit. The pack may also include one or more jokers of conventional design to be used as wild cards.
