• Normal Sudoku rules apply.
• Cells in a cage contain different values.
• A gold cell contains its position within its row, column, box or cage. Position is read from left to right, top to bottom.
For example the gold cell R3C6 contains either 6 (position in row), 3 (position in column), 9 (position in box) or 5 (position in cage).
• All possible gold cells are given.
For example the white cell R8C1 does NOT contain 1 (position in row), 8 (position in column), 4 (position in box) or 2 (position in cage).
