A question for my math-inclined brethren:
I'm trying out a game mechanic that uses Spot It's "Ray-Chaudhuri–Wilson theorem." First off, if you have never played Spot It it is simply designed and mathematically complex!
What i need is a card that has 5 items on it, and each item matches one on exactly one other card. Does anyone know how to do this? I'm lost in the math :)
