(best d4 shape is dodecahedron with 1-4 repeated 3 times, fight me) 

Shit in a pinch that's not a bad idea.

Purple (number up) team for sure. The only alternative I'll accept is the ones that look like crystals, but I mean c'mon they're just so cool they get a pass, numbers up pyramid is clearly the *correct* choice.

But then you can't tell at a glance what kind of die it is.

I got mine from [Math Art Fun/The Dice Lab](https://mathartfun.com/thedicelab.com/index.html). I also got their Orbiform d4, which rolls nicely and looks and feels great.

AFAIK Zocchi's d4 do not have numbering on the truncated part of the pyramid. I got mine from [Math Art Fun/The Dice Lab](https://mathartfun.com/thedicelab.com/index.html). I also got their Orbiform d4, which rolls nicely and looks and feels great.

Can’t roll a 0 on a D4. I think you’d need: (D8 mod 4) + 1 ? But that gets confusing. I think /2 and round up is easier?

You're right. Off-by-1 error. Would be a Z4 then.

Fill the holes with a resin of the same density as the bulk material to balance it and I'd have no issues against it.

Who needs glances when you have organization? There's also versions that use pips or roman numerals or other symbols to make them visually distinct. You could also get them in a different color. Inferior shapes should never be accepted for convenience.

Hmmmmmm...I'll allow it

I still fuck with this, the numbers are still on top!

Truncated D8 / 2 for the win! 

But do you do d8 mod 4 or ceiling(d8/2)?

I found a dodecahedral d4 once and I have been looking for more of those ever since

Make it a rhombic dodecahedron for extra style points.

I may be the only one here who doesn't care. Long as it's understandable, it's good enough.

Or two coins.

Determining the correct d4 layout is left as an exercise for the reader.

Two coins isn't the same thing mathematically. If heads = 1 and tails = 2 then: 1+1=2 1+2=3 2+1=3 2+2=4 Average is 3, and the lowest is 2. D4: 1 2 3 4 Average is 2.5, and the lowest result is 1. d8/2 (rounded up): 1/2=1 2/2=1 3/2=2 4/2=2 5/2=3 6/2=3 7/2=4 8/2=4 Average is 2.5, and the lowest result is 1.
