Matchstick puzzles are rearrangement puzzles in which a number of matchsticks are arranged as squares, rectangles or triangles. The problem to solve is usually formulated as: "move n matchsticks to make m squares, triangles, or rectangles". Some match stick problems are solved with planar topological graphs.[1][dubious – discuss]
Other matchstick puzzles require lateral thinking and are not just about making geometric shapes.
Different three-dimensional matchstick arrangements are also possible[2] as puzzles held together with friction.
