After seeing my Gear Cube, several people have suggested to me to build gears into a Megaminx. Such suggestions have been done both privately and publicly. While just saying "hey, build a geared Megaminx" may be easy, there is a fundamental question to the design: how many edges should have a gears

It is important to understand that not all edges can have gears. If more than 12 of the 30 edges have gears, then some parts of the puzzle can never move. This would make those parts non functional. Even with fewer edge gears, there will be situations that some turns are blocked. This is similar to a bandaged cube, like the Bicube. Total prevention of blocking would require zero or at maximum one gear. However that would not be much more fun, compared to a classic Megaminx. I chose to have the golden mean of six gears, as that number can be symmetrically spread over the edges of a dodecahedron.
