2. Edge-matching puzzle - Wikipedia

   en.wikipedia.org/wiki/Edge-matching_puzzle

   An edge-matching puzzle is a type of tiling puzzle involving tiling an area with (typically regular) polygons whose edges are distinguished with colours or patterns, in such a way that the edges of adjacent tiles match. Edge-matching puzzles are known to be NP-complete, and adaptable for conversion to and from equivalent jigsaw puzzles and ...
