Clueless Sudoku 9
(Published on 12. June 2025, 20:42 by AlfSmith)
• Normal Sudoku rules apply.
• 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 R5C1 is either 1 (position in row), 5 (position in column) or 4 (position in box),
and the white cell R2C3 is NOT 3 (position in row), 2 (position in column) or 6 (position in box).
Solution code: row three

What a fun puzzle! Lots of digit hunting, but all the logic felt fair and I really enjoyed this! Deserves way more than 80%

How does the rule work in regards to box eight, since the digit 8 couldn’t be placed due to the box containing no gold squares? I’m a little confused on the negative constraint
AlfSmith> Gold cells are not friendly cells; they contain the cell's position rather than its row, column or box number. White cells must NOT contain the cell's position.

But for the author's yellow and white examples, I would still be struggling with this great puzzle. A sensational concept that should make a series. Thanks for sharing.

New rule for me, so it's a fun solve.
