I have a grid of 25, I changed the colors to make it easier to visualize for this post. The white underneath is the root prim, and I don't want it to speak when clicked. Green is the prize giver, link 7. Orange is the hot range, link numbers 2, 4, 5, 6, 8. Cyan is the warm range, link numbers 3, 9, 17, 19, 22, 24. Blue is the cold range, link numbers 10, 11, 12, 13, 14, 15, 16, 18, 20, 21, 23, 25, 26. The ordering of the links in comparison to the grid is a bit random because that's just how I selected things while I was building it.
You don't have to use these numbers or anything, they're more outlining what I'm working with. I'd be happy enough with just being pointed in the right direction for using a list to compare against. I wanted to use a list of the ranges because I think it'd be useful to know for future projects, plus I didn't want to redo my entire linkset haha.
