This is honestly a legit die imo. I assume those balls are pretty well balanced.

[–] acockworkorange@mander.xyz 39 points 2 weeks ago (2 children)

Figuring out which number is up is PITA though.

[–] dfyx@lemmy.helios42.de 6 points 2 weeks ago

Even worse: with an odd number of sides, there are cases where none is up.

[–] Threeme2189@lemmy.world 4 points 2 weeks ago (1 children)

Roll it on a glass table and crawl under it to check which number is in contact with the glass.

I like the way you think.

I think the D120 is the maximum possible isohedral (geometrically symmetric) fair die. A golf ball is probably pretty close to fair, though number 327 seems like it might be more difficult to balance than 12, 20, 30, or 60.

A D326 with one face a reroll.

We have dice from them, the funny shaped dice are great to look at, terrible to stack

[–] HeyThisIsntTheYMCA@lemmy.world 1 points 2 weeks ago (1 children)

I'm just seeing a pattern here, but shouldn't you be able to go to 240? I mean, it'd have to be a big fuckin' die, but it seems like it should work.

[–] threelonmusketeers@sh.itjust.works 3 points 2 weeks ago* (last edited 2 weeks ago) (1 children)

shouldn’t you be able to go to 240?

Not really. The faces of the D120 are already asymmetric (scalene) triangles. There's no way to split these into additional faces while keeping them all the same shape.

Any larger geometrically fair die would have to be from an infinite family (prisms, bipyramids, and trapezohedra), which are "impractical in reality due to the tendency to roll for a long time".

[–] Hagdos@lemmy.world 2 points 1 week ago (1 children)

A tendency to roll for a long time would be true for any many-sided die, no? I can't imagine the 120 stopping quickly either.

[–] threelonmusketeers@sh.itjust.works 2 points 1 week ago (1 children)

Yes, but since faces are essentially distributed over a cylinder, rather than a sphere, it is more of an issue.

[–] Hagdos@lemmy.world 2 points 1 week ago

Ah yeah, that's a good point

[–] festnt@sh.itjust.works 8 points 2 weeks ago* (last edited 2 weeks ago) (2 children)

uhhh you can see there are gaps between some faces and there arent on others, so it really isnt well balanced

edit: i somehow typed f`ces

[–] unexposedhazard@discuss.tchncs.de 7 points 2 weeks ago (1 children)

Oh yeah u right, i didnt even look that close. I just assumed nobody would create such an asymmetrical atrocity. I can never look at golf balls the same. Not that i do ever look at them.

[–] threelonmusketeers@sh.itjust.works 2 points 2 weeks ago (1 children)

there are gaps between some faces and there arent on others, so it really isnt well balanced

But as long as all the faces are the same size, and the die never lands on the gaps (or is rerolled if it does), would that be a fair die?

[–] mipadaitu@lemmy.world 4 points 1 week ago

Unless some numbers are opposite of a gap, then it could never land with that number facing up.

Each side needs an opposing flat part, and I don't think that can happen with a die with an odd number of sides.

[–] Joeffect@lemmy.world 3 points 2 weeks ago

This is more of a spin down or a counting die than something you would roll

[–] chiliedogg@lemmy.world 14 points 2 weeks ago

Do opposing numbers add up to 328?

[–] kryptonianCodeMonkey@lemmy.world 13 points 2 weeks ago
[–] tourist@lemmy.world 9 points 2 weeks ago (2 children)

fuck it

I'd rather just fail the skill check

my head would burst trying to figure out which number is precisely on top

[–] SchmidtGenetics@lemmy.world 4 points 2 weeks ago (1 children)

Average the top 5 numbers?

[–] rain_worl@lemmy.world -1 points 2 weeks ago

that would be uneven, imagine averaging the top 327 numbers. would be better to add them up modulo 327

[–] Threeme2189@lemmy.world 1 points 2 weeks ago

Roll it on a glass table and crawl under it to check which number is in contact with the glass

[–] als@lemmy.blahaj.zone 6 points 2 weeks ago (1 children)

I wonder what opposite sides add to

In case it's a genuine a question, there isn't an opposite side to odd-sided dice. Had it been a d326 it would have been 326+1 in total, if it were a d328 it would be 328+1

[–] mobilehugh@lemmy.ca 4 points 1 week ago

Could also be used as 109 or 3 sided die.

[–] Jomega@lemmy.world 4 points 2 weeks ago (1 children)

I can't think of a single situation that would call for such a thing.

Game accessory shops have dispatched numerous assassins to your location. Godspeed.

[–] FinalRemix@lemmy.world 3 points 2 weeks ago

I bet he can't even roll for initiative!

[–] grue@lemmy.world 2 points 2 weeks ago

Why even use dice?

BURN THE HERETIC!

[–] Astronauticaldb@lemmy.world 4 points 2 weeks ago

Hey, now I know how many dimples the average golf ball has! (Plus a new way to torture my players!)

[–] Sam_Bass@lemmy.world 3 points 1 week ago

slow day huh
