ABSTRACT:
12-sided and 20-sided dice are disclosed which have a suit symbol and a value symbol on each surface representing one of the various playing cards in a standard 52 card playing deck. The 12-sided die will carry 3 different value symbols for each of the 4 suits and, accordingly, will depict 12 different cards, one on each of its surfaces which are identically shaped pentagons. A game is disclosed which employ three or more of such dice, all identical. In another embodiment a 20-sided die is provided which carries 5 values of each of the four suits. In all embodiments, parallel, opposing surfaces will bear the same value symbol and no two surfaces adjoined together along a common edge will bear the same suit symbol. This symmetrical arrangement provides for integrity of change in re-rolling the dice and complete randomness of chance.
