Maybe this is a dumb or off-topic question, and please see beyond my flippant language: but since dice are such an ingrained part of this hobby...

Recently I got in a fit of nerd-rage at the ungainly d4, and bought some blank d8s from my friendly local game store. A permanent marker and some spots later and I have 3d4 that actually roll...

...Much like the double-number d6s that some companies print for d3s, why isn't an 8-sided d4 simply the standard?

    \$\begingroup\$ I don't know, it seems like a matter of basic physics (mechanics) that an 8-sided polyhedron rolls much better than a pyramid? Please don't penalize my admittedly flippant language. \$\endgroup\$ – Michael Nov 24 '16 at 16:16

    \$\begingroup\$ We're not penalising the language. The problem here is that the question is asking “why isn't our reality different?” The only possible answers are speculation or personal theories — hence, the question (and its answers) are primarily a matter of opinion. This would be a fine discussion prompt for a discussion forum — it's not an inherently bad or inappropriate question — but pure opinion/speculation doesn't work on a Q&A site where we have to rank the resulting answers. \$\endgroup\$ – SevenSidedDie Nov 24 '16 at 19:25

    \$\begingroup\$ Why is this tagged accessibility? Is there an argument that d8 labeled 1-4 twice would work better for some disabled players? \$\endgroup\$ – nitsua60 Dec 14 '16 at 16:14

    \$\begingroup\$ @nitsua60 I answered you in chat as well but commenting here for the benefit of others. Pyramid-shaped d4s are difficult to pick up from a flat surface, even moreso if one lacks fine motor skills. It remains to be seen if that is the reason for the tag here, but it certainly could apply to the problem. \$\endgroup\$ – LegendaryDude Dec 14 '16 at 17:51

    \$\begingroup\$ I totally see what you're saying, @LegendaryDude. I guess I'd feel better if either the question were edited to explicate the accessibility issue or the tag were removed. (One hope I have for the tag is that one browsing the questions could learn a bit about how to make small, no-cost changes that improve accessibility, even in the absence of a disabled player. This question... doesn't seem to help one understand accessibility in RPGs at all.) \$\endgroup\$ – nitsua60 Dec 14 '16 at 22:06

There certainly are some rare d8 with two times 1-4 floating around, just like there are more common d20 that have 1-10 twice. However, games like D&D and Pathfinder that use both d4 and d8 or d10 and d20 don't gain a considerable benefit from these, even if they are better to roll:

You buy the better performance at actually rolling with the awkward situation of mixing up the d4/d10 for a d8/d20 or vice versa.

This means possibly wasting a perfect 4/10 on a d4/d10 roll by simply having grabbed a d8/d20 or trying to negotiate a reroll when you realize you rolled the d4/d10 instead of the d8/d20.

  • \$\begingroup\$ I just painted spots on my blank d8s, so it's easy to see the difference. My cubic d3s likewise have numbers whereas the d6s have spots... \$\endgroup\$ – Michael Nov 24 '16 at 15:36
