Questions tagged [dice]

Dice are small objects thrown by hand that land in different positions, used to generate random value for games, particularly gambling.

A die (plural dice) is a small object (most commonly a cube) designed to be thrown onto a surface. Markings on the face of the die chosen by how it lands indicate a value that is thereby chosen randomly. Dice have been used for centuries--even longer than playing cards--for gambling and other games.
