Matchstick Puzzle
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. Other matchstick puzzles require lateral thinking Lateral thinking is a manner of solving problems using an indirect and creative approach via reasoning that is not immediately obvious. It involves ideas that may not be obtainable using only traditional step-by-step logic. The term was first ... and are not just about making geometric shapes. Different three-dimensional matchstick arrangements are also possible as puzzles held together with friction. References {{puzzle-stub Puzzles ...

Matchstick Puzzle Examples
A match is a tool for starting a fire. Typically, matches are made of small wooden sticks or stiff paper. One end is coated with a material that can be ignited by friction generated by striking the match against a suitable surface. Wooden matches are packaged in matchboxes, and paper matches are partially cut into rows and stapled into matchbooks. The coated end of a match, known as the match "head", consists of a bead of active ingredients and binder (material), binder, often colored for easier inspection. There are two main types of matches: safety matches, which can be struck only against a specially prepared surface, and strike-anywhere matches, for which any suitably frictional surface can be used. Because of the substance used to coat each match, this makes them non-biodegradable. Etymology Historically, the term ''match'' referred to lengths of rope, cord (later cambric) impregnated with chemicals, and allowed to burn continuously. These were used to light fires and fir ...
