Marsh/Row 2



Localization: In the back of Row 1.

Name of the puzzles in game files:.

Tutorial for: this set of puzzles teaches that the puzzles can contain more than one polyomino, and that a zone can contain multiple polyominoes. So the basic rule should be rephrased: “in each area that contains polyominoes, there must exist an exact paving of this area with the polyominoes it contains.”

Manifestation of principles: Because only the first puzzle can be solved without putting the two polyominoes in a same area, this Row can be understood as being about union of polyominoes, a concept related to the one of connecting distant or separated elements.

Heuristic learnt: In the solution paving, a polyomino does not have to cover the cell that contains its symbol. In some occasions it is necessary to move the polyominoes around slightly to solve the puzzle.
