  • Patent number: 7549643
    Abstract: A playing card system is disclosed comprising a face side displaying markings, which can be hidden and revealed by an adjustable barrier. A set of these playing cards may be used in the same games as those using a standard deck of cards. A shuffler randomizes the order and/or arrangement of the one or more sets through an agitation mechanism. The shuffling system allows for heightened randomization and secrecy of the markings, and minimizes opportunities for manipulation.
