About Die (plural DICE) according to wikipedia.org:
A die is a small throwable object with multiple resting positions, used for generating random numbers. This makes dice suitable as gambling devices for games like craps, or for use in non-gambling tabletop games.
A traditional die is an often rounded cube, with each of its six faces showing a different number (pips) from 1-6. Its design assures a randomly determind integer.
