Meffert’s David’s Gear Cube Puzzler – Level 8

Description

The Gear-cube is a brand new concept in cube design and has the following inventive steps. This puzzles combines a corner-and-center-turning gear cube with a twisty 2 x 2 x 2 cube. Whereas it is easy to return the puzzle to its cubic shape, it is quite a challenge to get all gear segments to their right face, and even harder to solve the puzzle as a whole.
