David's Gear Cube - Black body

David’s Gear Cube – Black body David’s Gear Cube is a geared twisty puzzle inspired by the Gear Cube. It was conceived by David Tzur (previously known as Alex Polonsky) and developed by Oskar van Deventer, one of the world’s most prolific puzzle designers. This puzzles combines a corner-and-center-turning gear cube with a twisty 2x2x2 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.

The simplicity of the puzzles is misleading. Although the concept is quite simple – finding the pieces and repairing them together – an amazing level of mental activity is required to complete the necessary steps to complete a puzzle. Psychological studies have identified a number of thought processes that are necessary to achieve what is in fact a complex process of identifying shapes and images and relating them to a general pattern. More importantly, solving puzzles is great work for the brain and can have therapeutic benefits.
