More OskarPuzzle at Print it yourself at Buy at or at Panex Junior is a simplified version of the classic Panex puzzle, invented by Toshio Akanuma and manufactured by Tricks Company in Japan in the 1980’s. Whereas the original Panex puzzle has two columns of ten pieces that need to be switched, Panex Junior has only a single column of six pieces. This makes it much easier to solve. The staircase design assures that each color can only be moved down to its specific depth. Copyright (c) 2021, M. Oskar van Deventer.
