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
