Dice

From MagicPedia

Dice are often used as a substitute to balls - for example, doing a cup and ball routine with dice instead of balls

However, certain effects are unique to dice:

Dice Stacking - A cup is used to shake the dice, and when the cup is lifted, the dice are stacked on top of one another in a single column. Often perceived by magicians as a juggling trick.

Seems to be described first in Shoot the Works by Edward Marlo in 1943.

Number Tricks - Tricks that rely on dice properties (eg, that opposite sides add up to seven)
