• Normal Sudoku rules apply.
• Disjoint Groups: Cells with the same position within the boxes contain all the numbers 1 to 9.
• A gold cell contains its position within its row, column or box (in normal reading order).
For example the gold cell R4C6 contains either 6 (position in row), 4 (position in column) or 3 (position in box).
• All possible gold cells are given.
For example the white cell R7C5 does NOT contain 5 (position in row), 7 (position in column) or 2 (position in box).
Solution code: row seven

Brilliant - I really clueless Sudoku and the disjoint set made a challenge for me (as usual :) ). Thanks for sharing and keep them coming!

Lovely! I'm a sucker for disjoint groups, and the golden cells were a nice new twist! :)

It would have helped my solve if i didn't keep confusing the box NUMBER with the box POSITION. ;)
