In any legal position (reachable from the solved state without disassembling the puzzle), there is always an even number of swapped pairs of edges. However, since swaps may be between visually identical edges, one may find that having solved almost the entire puzzle, one is left with a pair of swapped (distinct) edges that seems to defy all attempts to exchange them. The solution is to swap a single pair of 'identical' edges to resolve the parity issue, and then restore the rest of the puzzle. 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 Megaminx the regular way, patterns can be made on it just like a Rubik's Cube. Examples of these include a star, checkerboard, and pentagon in a pentagon patterns. Variations [ edit] 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.

A 6-color Megaminx, solved A 12-color Megaminx, solved A 12-color Megaminx in a star-pattern arrangement 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 [ edit] 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. [1] It is also known by the name Hungarian Supernova, invented by Dr. Cristoph Bandelow. [2] His version came out first, shortly followed by Meffert's Megaminx. The proportions of the two puzzles are slightly different. Description [ edit] 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.
