Marsh/Row 3

Localization: In the metal structure upstairs.

Name of the puzzles in game files:.

Tutorial for: This set of puzzles with red backgrounds require you to master the idea introduced by Row 2, that areas can contain more than one polyomino and that these polyominoes will not necessarily be used in the same configuration than the cells containing them. However, in the puzzles of Row 3, it is mandatory to have all polyominoes in a same area (or possibly two areas, for the last puzzle of the row), and it is also mandatory to change their relative positions so that a polyomino covers the cell containing a different polyomino.

Heuristic learned: Row 3 is thus a tutorial for a new kind of puzzle that exploits the basic polyomino rule in a different way: here, you have to find a way to arrange all the given polyominoes so that they form a connected path going through all the marked cells. So the principle is to move the polyominoes so that they connect distant cells.

Manifestation of principles: This heuristic is exactly the principle of connecting distant or separated elements announced by the first moving platform (which connects rows 3 to row 2 where the heuristic is introduced), but here, it is a static implementation of that principle. Completing this row opens a door below, which is also a way to connect distant or separated areas. The idea to arrange the polyominoes so that they make a path is also reflected in the design of the Marsh by the way metal platforms are used to make walkable paths, in accordance with the puzzle/world analogy.
