N-dimensional sequential move puzzle have succeeded in finding them on all similar puzzles that have so far been solved. A 2-D Rubik type puzzle can no more be physically constructed than a 4-D one can. A 3-D puzzle could be constructed with no stickers on the third dimension which would then behave as a 2-D puzzle but the true implementation of the puzzle remains in the virtual world. The implementation shown here is from Superliminal who call it the 2D Magic Cube. The puzzle is not of any great interest to solvers as its solution is quite trivial. In large part this is because
Missing square puzzle under the mark in the upper image, but goes through it in the lower. Overlaying the hypotenuses from both figures results in a very "thin parallelogram" (represented with the four red dots) with an area of exactly one grid square, so the "missing" area. According to Martin Gardner, this particular puzzle was invented by a New York City amateur magician, Paul Curry, in 1953. However, the principle of a dissection paradox has been known since the start of the 16th century. The integer dimensions of the parts of the puzzle (2, 3, 5, 8, 13) are successive Fibonacci numbers, which
