The Megaminx or Mégaminx (, ) 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. History The Megaminx, or Magic Dodecahedron, was invented by several people independently and produced by several different manufacturers with slightly different designs. Uwe Mèffert eventually bought the rights to some of the patents and continues to sell it in his puzzle shop under the Megaminx moniker. It is also known by the name Hungarian Supernova, invented by Dr. Christoph Bandelow. His version came out first, shortly followed by Meffert's Megaminx. The proportions of the two puzzles are slightly different. Description The Megaminx is made in the shape of a dodecahedron, and has 12 faces and center pieces, 20 corner pieces, and 30 edge pieces. The face centers each have a single color, which identifies the color of that face in the solved state. The edge pieces have two colors, and the corner pieces have three. Each face contains a center piece, 5 corner pieces and 5 edge pieces. The corner and edge pieces are shared with adjacent faces. The face centers can only rotate in place, but the other pieces can be permuted by twisting the face layer around the face center. There are two main versions of the Megaminx. The 6-color variant uses the 6 colors common to puzzle cubes - white, yellow, blue, green, red and orange - with opposite faces having the same color. The 12-color variant uses a unique color for each face of the puzzle. The most common 12-color scheme starts with white bordered by yellow, dark blue, red, dark green and purple. Directly opposite each of these faces, respectively, are gray, beige, light blue, orange, light green and pink. Black is a common alternate face color, either replacing gray which improves color contrast on what is typically the last layer solved, or replacing beige, which typically shares two neighbors (red and green) with the white face which can make piece identification challenging in certain lighting conditions. The 12-color Megaminx is the only type legal in official WCA competitions (color scheme variations are legal as long as each face is uniquely-colored), and is therefore much more popular than the 6-color version. The objective of the puzzle, similar to that of a Rubik's Cube or related puzzles, is to scramble the
