I made this puzzle for my friend jovi_al's birthday! She likes friendly cells so I came up with this ruleset. The difficulty is probably around 4.5/5 stars.
-) Classic Sudoku rules apply. (place the digits 1-9 once each in every row/column/box)
-) Green cells are friendly cells (they contain their row/column/box number; e.g. r5c9 could be 5(row), 9(column) or 6(box)
-) There is EXACTLY 2 friendly cells in every row/column/box of the grid
Solution code: Column 2 + Column 6, no extra characters.

Wow, that puzzle was awesome. The break-in is fascinating and even after that there are a few things to uncover, but with a very nice flow. Thank you so much for building this beauty, JoWovrin!

Very nice, but only 3 stars difficulty for me (and I made an erroneous assumption at the start, without which it would've been 2.5 stars).

It's really insane to see how restricted it could be, quite challenging continuous scannings but really rewarding. Wonderful puzzle! :)
