The MEGAMINX (/ˈmɛɡəmɪŋks/ or /ˈmeɪ-/ ) is a dodecahedron -shaped puzzle similar to the Rubik\'s Cube . It has a total of 50 movable pieces to rearrange, compared to the 20 movable pieces of the Rubik's Cube.

independently and produced by several different manufacturers with
slightly different designs.
DESCRIPTION The
There are two main versions of the Megaminx: one with 6 colors, with opposite faces having the same color, and one with 12 different colors. The purpose of the puzzle is to scramble the colors, and then restore it to its original state of having one color per face. SOLUTIONS The 6-color
This property is absent in the 12-color Megaminx, because all its edges are distinguishable, and it would be immediately obvious that there is another pair of swapped edges besides the pair one is working with. Besides solving a
VARIATIONS There are many similar puzzles with different numbers of layers, most
of which change the "mega" in the puzzle's name to another metric
prefix . They are the Kilominx (2 layers), Master Kilominx (4 layers),
Gigaminx (5 layers), Elite Kilominx (6 layers), Teraminx (7 layers),
Petaminx (9 layers), Examinx (11 layers), Zettaminx (13 layers), and
Yottaminx (15 layers). The highest order mass-produced variant of
the
Alexander\'s Star is equivalent to solving only the edges of a 6-color Megaminx. The
