This is a quick wiki search "The puzzle was created by Franz Owen Armbruster, also known as Frank Armbruster and published by Parker Brothers in 1967. Over 12 million puzzles were sold. The puzzle is isomorphic to numerous older puzzles, among them the Katzenjammer puzzle,[3][4] patented[5] by Frederick A. Schossow in 1900, and The Great Tantalizer (circa 1940, and the most popular name prior to Instant Insanity). The puzzles use a subset of the 30 cubes devised by Percy Alexander MacMahon, but it is not known if the puzzle creators knew of MacMahon's cubes." I have a puzzle that does indeed have 12 different possible shapes and fits together in a rectangle. You have connected the ends together as if it will be folded like oragami. Why? |
