Any regular bi-pyramid would be technically fair. I think it's just that you tend to get rounder dice by using platonic solids or tesselating / modifying platon

By the way, you can get d100 dice.

I know the “Zocchihedron”, one of the first and best known commercial ones, is not fair (after this was proven, they were renumbered so that the over-/under-weighted results were better distributed over the range, but it's still not fair.)
- ummonk 5y agoWow, I'd seen one but never actually checked whether it was fair.
- JohnHaugeland 5y agoYes. By trivial example, two fifty sided pyramids joined at the base. These can be purchased. Most players use d10 pairs with a tens die, though, because they roll better.
- mkl 5y agoAlso a 100-sided cylinder. Probably hard to read though. Do you have a link for the pyramid one?
- JohnHaugeland 5y agoNo. I bought it 25 years ago in a game store called "Games Unlimited" in Pittsburgh, PA.
- ajuc 5y ago> Most players use d10 pairs with a tens die, though, because they roll better. There's also a nifty trick used in many RPGs based on d100 to roll once and have 2 d100 numbers (by inverting the result). So for example in Warhammer you roll d100 for attack, you hit if your result is lower than your Melee Combat attribute, and the inverted result shows which part of the enemy body you hit (that influences critical hits and armor).
