Logic Masters Deutschland e.V.

• 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 R6C4 is either 4 (position in row), 6 (position in column) or 7 (position in box),

and the white cell R3C5 is NOT 5 (position in row), 3 (position in column) or 8 (position in box).
