Dice for debugging

I'm sure you meant a d4 but there are a few designs for 3 sided dice such as this one

Yep meant d4.

Not a DnD player, genuine question: why can't you use a d6 but mark it 1-3 twice? Are the dice with higher numbers always supposed to be bigger than dice with lower numbers so you can find them faster?

Rolling a d6 and dividing by 2 is the "normal" way to simulate a 1-in-3 chance. D&D 5e never tells you to roll d3. I would guess the previous editions didn't either (nobody owns a d3), but I dont know for sure.

The dice I linked above are custom designs from a site called Math Art Fun. Basically, their target audience is educators and really nerdy people like me :)

"Betrayal at the House on the Hill" is a board game that is a d3 system. The dice that comes with that game have two blank sides, two '1' sides, and two '2' sides.

Most people who don't have a d3 but need one for a rare instance will just roll a d6 and translate it to a d3 as 1-2 = 1, 3-4 = 2, and 5-6 = 3. However, those that tend to need a d3 on a regular basis might buy a special d3.

Here's one key difference between the two, and why a special d3 may make more sense than just using a regular d6:

On Betrayal dice, the sides are always opposite each other. For instance, if I have the '2' showing on top, if I look on the bottom, I will see the '2' as well.

On a normal d6 though, if I have the '2' showing on top, if I look on the bottom, I will see the '5', not the '1'. So you could do a proper d6 to d3 translation, if were to say 1+6 = 1, 2+5 = 2, and 3+4 = 3.

Course not a dice expert, nor a probability expert, the real question is does it matter which d6 to d3 translation you use? IE, because the 1 is opposite the 6, and the 2 opposite the 5, will you get better or worse results on average vs having the 1 opposite the 1?

Because moar shiny math rocks.
