Bell Dice
Dice whose distribution is a descrete integer value aproximation of a bell curve. Bell dice designed to closely match the mean and standard deviation of a flat distribution polyhedral die, commonly designated Dn, and with m sides, may be designated as a Belln:m. While the mean and standard deviation may be a close match, the min and max may vary from the base Dn. Where a smooth distribution is desired larger number of side is desirable.
Curiously, Belln:n, where n <= 10, has the same distribution as a Dn.
Bell dice may be used to obtain the randomness of a difficult to obtain or physically impossible die size. A sampling of Belln:6 :
