• Normal Sudoku rules apply.
• Solving a cell clears any fog from its immediate vicinity.
• A gold cell contains its position within its row, column or box (in normal reading order). All gold cells are given.
For example the gold cell R5C9 is either 9 (position in row), 5 (position in column) or 6 (position in box),
and the white cell R5C7 is NOT 7 (position in row), 5 (position in column) or 4 (position in box).
Lösungscode: row three

This got easier when I read the rules correctly

Time-wise, this was 2 stars for me, but that was mainly due to an extended "hunt the pixel" session towards the end before I found what I had neglected way earlier. Still enjoyable.

Maybe I did this the wrong way, because I liked the idea but I ended up just pencilmarking all white cells in bulk and then doing normal sudoku

Not too difficult but some deductions using the negative constraint felt well earned. Really loved it!!

I was going to say "I don't think it warrants four stars" but I see the group tally already agrees with me. However, what it was was enjoyable and fun to see how one simple rule set slowly unraveled the 81 digits.
