CHX XSDC15 Speckled Lathyrus 8-Sided Doubling Cube

Although called a cube these dice can be any shape with sides that start with the number 1 or 2 and then the other sides are in multiples of 2 from the lowest numbered side (such as 1, 2, 4, 8, 16, etc. or 2, 4, 8, 16, 32, 64, etc.). The doubling cube can be added to any game where multiple games are being played, like speed chess, cribbage, checkers, etc.
