The 20 white tiles are identified with their black dots; for example (2,2,0) represents the tile with two black dots in the first and second corner and zero dots on the third.If the solution says put tile (1,2,3) on face [11,12,7], then you must put the white tile on the bottom-left face, and rotate it until 1 black dot is on yellow pin 11, 2 black dots are on yellow pin 12 and 3 black dots are on yellow pin 7. You can also generate a random yellow pins configuration clicking “Random IcoSoKu”.
Pin B: Pin C: Pin D: Pin E: Pin F:
Pin G: Pin H: Pin I: Pin J: Pin K:
I didn’t tested the solver too much, so if you find a wrong solution or a pin configuration that doesn’t produce a solution, please post a comment below to help me fix the bugs.
UPDATE 14/08/2021: since my solver was published on this blog, a few papers have been published about IcoSoKu:
