• 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).
For example if cell R4C8 is gold then it contains either 8 (position in row), 4 (position in column) or 2 (position in box).
• All possible gold cells are given.
For example if cell R7C9 is white then it does NOT contain 9 (position in row), 7 (position in column) or 3 (position in box).
Solution code: row nine

It‘s not about the box number but the position in the box @wuc

Tell me what am I missing. Since r6c4 is white it cannot contain 6 4 or 5...
