This 100 sided dice from Gamescience is a great way to use a simple single roll for generating a 1 to 100 number. No longer must you use two D10 and try and remember which one each player rolls first. One die, one roll, and no doubt.

The surface of the die is covered in clear plastic and the internal mirrorshade silver ball is numbered 1 to 100 with white numbers. This is not your usual solid die. The die is hollow, with loose weighting inside so that as it rolls the weight shifts to the bottom to help it come to a stop on one of the sides, and we suspect to assist with randomizing the results. When you shake the die, it will actually rattle. This dice measures 38mm tall.
