The edge of a coin is a 3rd side though
every other die has sides that aren't counted if you're doing that.
dice are just flattened spheres. they only have one weirdly shaped side
A side in this case is a specific area that allows for differentiating outcomes
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.

If you wanna get loosey-goosey with it and count the curved bit as a result, its still just a d6 lmao
Looks 4-sided to me
Agreed, but also weird as aren't d4 made from 4 triangles?
Fuck caltrop d4s, all my homies hate caltrop d4s (it's me, I'm all the homies)
Usually, yes. This one is effectively a d6 (a cube), but two of the flat faces have been replaced by curves that connect opposite flat faces. As such you've got four flat faces that the die can actually stop on. If you ignore the curved parts but consider all of the flats to be separate faces, it's a d4. If you consider two flats connected by a curve to be a single face altogether, it's a d2.

Or you know, a coin.
Coins are just really unbalanced three-sided dice.
aka really short cylinders
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.
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.
Even not considering that, they still aren't 50-50 odds. The stamped printing on both sides throws off the balance just enough to bias one side over the other.

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.
This website looks like it was made in 1999, but it documents a project from this year. I love it. It loaded nearly instantly on my phone.
thank you for this blessed website in trying times

This was my thought.
Mfers be out here debating whether the thing depicted is actually a "two sided" dice, meanwhile coins just be chillin over there getting ignored.
Y'all be trippin.
Too expensive.
Don't be ridiculous, obviously you roll a d20, subtract one, and then count how many digits the result has
Roll a d100, if it is odd 1, 2 if even
I like how you'd be rolling two d10's, and then completely ignoring one of them.
It keeps the statisticians happy
I need to get one of these sometime
At first glance I thought this was an AI generated picture of a roll of toilet paper..
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
One of my overdue projects is to disassemble a magic 8 ball, remove the dice from it and make a digital magic 8 ball. I plan to bequeath the removed “dice” to a DM I know.
Make sure to wear long gloves and short sleeves. The dye in that water is strong. I was purple for days after cracking an 8ball and people kept asking how I got hurt.

I've seen this shape uses as a D4. Nothing cursed about it. About as threatening to me as a Labrador puppy.
this is four sides??
That's a weird looking coin
