 Solving it cleanly took me quite some time. On the other hand, the post-mortem analysis showed that the solver requires only one correct digit to solve it. Meaning that the puzzle is objectively (?!) rather easy.

I don't know how to provide a hint that doesn't give too much away. Maybe this one: Neither row F nor column 7 do contain a 2.

  • I'd prefer hints like: single pair in col or xwing on ... So I could find the way instead of cell solutions.
