>a triangular prism
>fair as a die

There is a Goldilocks zone where the prism is just long enough to land on its rectangular faces as often as it lands on its triangular ones, but where that zone is varies depending on what the die is made of and what the surface you're rolling the die on is made of. You know that superstition that says you have to reroll a die if it rolls off the table? With a triangular prism d5 you might actually need to do that to make sure the roll remains uniformly random, MAYBE unless the floor is made of the same material as the table.

It's a reasonable conjecture to say that the same thing goes for the other irregular dice, so at my table, the burden of proof is on you when you say that you're fair.

>>52515856
If you want to bitch about the dice players use, don't play a system that would make them need irregular dice. Any company that makes dice should design their dice to be truly random.

You should always reroll dice that fall off the table anyway.

>>52515856
>>52515204
The d7 is patented by Zocchi of GameScience dice.

It's actually a fair die, the patent is the ratio/length of the prism being the "Goldilocks" zone where all faces are equally likely.

No idea if it was calculated or determined by experimentation, but I've seen people test it.

>You should always reroll dice that fall off the table anyway.
Why? If the die is fair and a single side is facing upwards, as long as it's a fair die, the outcome will have been probabilistically equivalent irregardless of where the die landed. You're right that companies *should* make their dice random, but that doesn't mean they will. They'll make whatever people will buy.

Eh.

We've got d% for d100, I think there could be a medium between coins and golfballs.

d% works under non-base10 for literally anything. Eg, dHexadecimal

>>52516921
The icosahedron is a platonic solid and therefore better.

>>52516981
Doesn't classic Traveller actually use dHexadecimal for one thing or another?

>>52517032
Dunno.

Square numbers only though?

dBase2 = d4
dBase3 = d9
dBase4 = d16
dBase5 = d25
d36
d49
d64
d81
etc

dHexadecimal like d% would be a d256

>>52517119
As long as you have a dN and dM for such that MN = X, you have a dX.

d8 + 8(d2 - 1) = d16.
d4 + 4(d3 - 1) = d12.
d10 + 10(d3 - 1) = d30.

It's the higher prime numbers and the multiples thereof that give you trouble. But even then you can just have a die designed like pic related with twice that many sides and then modulate it by 2.

>>52517119
Oh, and by dHexadecimal I meant Traveller used a d16 expressed in hex, from 0 to F.

Do you also believe that global warming is a hoax?

If you have to flip through the [DCC] book to remember which dice to roll in a particular situation, then maybe you should be looking at a more commonly utilized probability, and then choose the dice to match.

>>52516170
Did you even read my post?

As soon as you introduce geometrical irregularities to the die, the result starts to depend on outside factors such as what surface you're rolling the die on and what the die is made out of.

Is chessex a meme?

>>52524966
Nah. Gamescience is the meme dice brand.

I don't care about "fairness" of a dice brand, but I unironically like gamescience dice from an aesthetic standpoint.

Pic related has a combat system remarkably similar to dnd, except the damage dealt by each attack is a random amount from zero to the maximum possible with whatever weapon and strength is used.

So if you made a game which modeled that with dice, you'd need every dice up from d2-1 to d135-1.

Don't know why I even bought it. Just for a 'weird die' I think. Never used it.

Metal dice seem like a good idea before you get them, but they are seldom worth it. They are almost always more difficult to read, and sometimes you can't use them due to whatever surface you are rolling on.

And how would you do go about that, adding up the values of the faces? That wouldn't work; see pic related.

>>52531777
The latter. It has more symmetries -- on the platonic icosahedron, every face, edge, and vertex is identical to every other both in its dimensions and in its relative position to every other face, edge, and vertex; whereas on the pentagonal bipyramid, that's only true for the faces. It's still pretty hard to throw deliberately though.

Numberphile's series on dice geometry should be required viewing for anyone who wants to talk about the fairness of dice on this board.

>>having a dedicated D4 and not just tossing two coins

I know this is bait, but tossing two coins has three possible outcomes not four;

Heads-Heads
Heads-Tails
Tails-Tails

It is.

>>52539050
Heads-Heads
Heads-Tails
Heads-Edge
Tails-Tails
Tails-Edge
Edge-Edge
Coins have three sides.

>>52539050
With combinations that's true, but not with permutations. That's like saying there are only 55 possible outcomes on d%. If it matters which coin is heads and which coin is tails, you have four outcomes: HH, HT, TH, and TT.

I hate the loose/non matching sets like you get in pound o' die

Curious if anyone knows of a place I can order custom die? of course 3D printing is an option, but those die are unbalnced pieces of garbo.
