a two sided die is called a coin

[-] binomialchicken 8 points 3 days ago

The edge of a coin is a 3rd side though

[-] mikesizachrist@lemmy.world 14 points 3 days ago

every other die has sides that aren't counted if you're doing that.

An ideal coin is perfectly flat with no thickness.

Coins are just really unbalanced three-sided dice.

[-] Rhaedas@fedia.io 32 points 4 days ago

The odds of a US nickel landing on its edge is about 1 in 6000. If there are any other country's coins thicker the odds would probably get better.

[-] porksnort@slrpnk.net 25 points 3 days ago

A standard US nickel, yes.

I prefer better odds than that…

Thick Nickels

[-] HakFoo@lemmy.sdf.org 14 points 4 days ago

The old UK £1 was similar in size but twice as thick. It's now 12-sided but not sure how that impacts the odds.

[-] Rhaedas@fedia.io 17 points 4 days ago

I know there's a way to figure that out, but I have no idea where to start. So I'm going with 1 in 3000, plus or minus 42.

That extremely rare, almost-never chance of landing on the edge is exactly what I would program into a game if I made one, instead of exactly 50% odds.

[-] Evil_Incarnate@sopuli.xyz 2 points 2 days ago

I brought this up in maths class once. The teacher agreed that the edge was a possibility and since he was involved in football, they used to flip the coin and let it land on the ground. More than once it stuck in the mud in the edge.

Then told us to ignore that possibility.

[-] Remember_the_tooth@lemmy.world 7 points 3 days ago

It should come with some bizarre consequence, too. If it were the Oregon Trail game, there should be a tiny chance that the player finds an ancient artifact that glows and hums when touched. An alien ship swoops in and abducts the party, forcing them to join the crew. From there on, it's a space pirate game with zero explanation why and no references in the product literature. Also, customer service pretends not to know about it, if contacted.

Don't be ridiculous, obviously you roll a d20, subtract one, and then count how many digits the result has

[-] programmer_belch@lemmy.dbzer0.com 15 points 4 days ago

Roll a d100, if it is odd 1, 2 if even

[-] Archpawn@lemmy.world 24 points 4 days ago

I like how you'd be rolling two d10's, and then completely ignoring one of them.

[-] ExplosiveLynx@lemmy.world 14 points 4 days ago

It keeps the statisticians happy

The picture is of a d4. Dice are measured counting the flats (and therefore possible number of different results) not mathematically defined "sides".

No, dN means there are N different outcomes. Does not matter if they are flat or anything. Cube with two of each number from 1 to 3 is a d3.

This gave me an idea for a gimmick die. Transparent die filled with dark liquid. The exterior of the die has the usual numbers in white lettering. Inside the die, there is a smaller cork die that rises like a magic 8ball. It’s 2d(x) in 1. Interesting for tension building, if nothing else.

Edit: looked it up and I’m not original, and they’re largely as bad as I thought they’d be

It's four-sided, not two-sided. If that one counts, you can also just use a regular six-sided one and just put three 'ones' and three 'twos' on it.

[-] DmMacniel@feddit.org 25 points 4 days ago

This die can only ever land on two distinct sides so it has two sides.

[-] Rhaedas@fedia.io 16 points 4 days ago

Incorrect. It can land on two different sides. Or it can roll off the table and under something, leaving you in a state of limbo.

It has two sides. They're curved, and it doesn't stay on the curve part, so you can effectively use it as a d4, but it's still only two-sided.

Sort of like how you can flip a Mobius strip like a coin and it will land one of two ways, but it still only has one side.

At first glance I thought this was an AI generated picture of a roll of toilet paper..

[-] mydude@lemmy.world 20 points 4 days ago

That's a weird looking coin

[-] Abrinoxus@lemmy.today 15 points 4 days ago

this is four sides??

[-] Iron_Lynx@lemmy.world 15 points 4 days ago

I've seen this shape uses as a D4. Nothing cursed about it. About as threatening to me as a Labrador puppy.
