You will never need that many icons, but I did them anyway. 230 icons included, 23 unique symbols, 2 forms & 7 colors (Yes, for this I'm counting black & white as a color)!

Some Icons were reused from the base game and included in the pack.

Currently included: Each type in 7 colors: Green, Yellow, Red, Purple, Blue, White & Black and square form
