Frequently asked questions
What is a d%?
A d% is a ten-sided percentile die marked 00, 10, 20, 30, 40, 50, 60, 70, 80, and 90. It is not a 100-sided die — it is the tens die in a 7-piece set.
Is d% the same as d100?
No. d% rolls one tens face (00–90). 1d100 rolls a single result from 1 to 100. To mimic physical percentile dice, roll 1d% plus 1d10 (or roll both from the quick tray).
