- 2Leave at least one empty square between two blocks. For example, 2 1 means two filled squares, a gap, then one filled square.
- 3A 0 clue means the entire line is empty. Cross off empty squares to help your reasoning.
- 4Fill every correct square to finish the picture. Empty squares do not need crosses. Undo is always available before finishing.
