In typical dungeons and dragons notation
, a d100 is a hundred sided die. Normally this is emulated by rolling two ten sided dice and having 0/0, or 10/10 be one hundred. It's a fairly good system for determining raw percentages.
I have however at one time, seen an actual one hundred sided die. It was this weirdly shaped plastic ball
, that contained sand. It was rather strange and hard to roll
. It was about the size of a half dollar
, probably a little bigger if memory
serves. The point was to roll it, and it would magically stop on some number. It was weird and a freakish novelty for some RPG
gamer somewhere. I never bought it, since it was a little over ten dollars for a piece of cheap plastic that would eventually break.
My advice: Stick with 2d10 for getting a percentage
; although you could impress all of your friends with this large and strangely amusing device
