There are many different shaped / sized / colored / textured puzzle-cubes similar to the standard 3x3x3 Rubik's Cube, but which provide entirely unique challenges.

Note that this category is strictly for puzzles which are in the form of a cube when solved (such as the Mirror Cube) or which have a cubic mechanism (such as the Pyramorphix, which is a shape mod of a Pocket Cube). Puzzles which are neither of these. such as the Megaminx, do not belong here (the Megaminx should be in Category:Dodecahedra).
