A playing device, in particular, a die having a body shape as a regular dodecahedron having twelve faces and a plurality of countable indicia one to six. Each total from one to six appears on precisely two opposite faces. Moreover, the two faces containing a given total lie on parallel opposing faces so that each opposite face is provided with the same number of recesses and therefore the die will be evenly balanced at all parts from its center. Each indicia is conical in shape and is recessed in the body adjacent to the dodecahedron faces. The faces of the die are pentagonal in shape and the placement of the indicia are such that the indicia on each planar face is identical to the number of indicia on the opposite planar face parallel to the first mentioned planar face. Thereby providing a perfect balanced die with its center of mass coincides with its geometrical center whereby greater random playing results are achieved and less chance for trickery.
