• Normal Windoku rules apply (place the digits 1 to 9 without repetition in every row, column, box and window).
• A gold cell contains its position within its row, column, box or window (if applicable). Position is read from left to right, top to bottom. For example the gold cell R2C8 contains either 8 (position in row), 2 (position in column), 5 (position in box) or 3 (position in window).
• All possible gold cells are given. For example the white cell R6C1 does NOT contain 1 (position in row), 6 (position in column) or 7 (position in box).
Solution code: row one

A very nice puzzle with interesting interactions between gold cells and Windoku.
