Logic Masters Deutschland e.V.

• Normal Sudoku rules apply.

• Chess: Cells separated by a king's move or knight's move cannot contain the same digit.

• A gold cell contains its position within its row, column or box (in normal reading order).
For example the gold cell R5C7 contains either 7 (position in row), 5 (position in column) or 4 (position in box).

• All possible gold cells are given.
For example the white cell R3C2 does NOT contain 2 (position in row), 3 (position in column) or 8 (position in box).
