Abstract
A deck of playing cards preferably comprising sixty two-value cards, whereby the deck consists of three different suits with four different number values per suit, and twelve half-wild cards consisting of a fifth number value which is wild in terms of its suit. The deck is uniquely designed so that every number value of a given suit is paired once with every number value of the other suits. In this manner, the deck constitutes a fair deck in which the probabilities of any given dealt hand can be predetermined so that successful winning stratagies can be developed. The deck is mathematically designed to overcome the statistical inadequacies of two-valued cards of the prior art. The deck may also be supplemented with a die representing the different suits, for games in which one suit ranks differently than another suit.
