Wow, this is ... something. And I mean this in the best way possible. Brilliant idea, excellently executed! I think one of the hardest things was figuring out how to pencilmark digits in the least confusing way :D

Mind-bending but some very nice logic comes out of it.

I feel the logic needed to break through this puzzle is very unintuitive, so it's probably 3* for me. Very mind-bending but interesting puzzle, so thanks .w.
