Abstract
Dice are disclosed which are generally spherical and which have a multiplicity of flat faces bearing indicia--symbols, letters, numerals or the like formed thereon by cutting, etching or engraving. The faces are arranged in opposed identical pairs with their centers lying on axes passing through the center of the die. In passing through the center of the die the axes may be symmetrically spaced one from the other or be arranged such that their angular spacing in both bearing and elevation is maximized.

A die comprising a center and a plurality of faces arranged in opposed pairs on opposite sides of said center, said faces being substantially identical and substantially equally spaced from the center of the die, each of said faces including a center point substantially lying on an axis passing through the center of the die, said axes being substantially symmetrically spaced one from the other relative to the center of the die, wherein said plurality of faces comprises fourteen substantially circular faces defining seven equilength axes, said axes having bearings and elevations relative to a reference axis substantially as follows:
