English: Notionally, there is no mathematical limit to the number of values from which a throw of a fair die may choose, if the die need not be limited to a single shape such as cubic. These are a few commercially available dice of various shapes: tetrahedral, hexahedral, octahedral, decahedral, dodecahedral, and spherical (which in this case gives any of six possible values, much as a cube does. Its internal structure prevents it from landing with an ambiguous value).
