Shift Happens

This puzzle has a very nice design and can be enjoyed by both young and old. It can help improve your learning and memory.

You can see a set of gears all locked together on the front side of the puzzle. There is a complete jam and nothing moves. It can only move because of the clever mechanism inside, allowing the back pieces to move.

You can scramble this puzzle by turning the pieces and shifting it back.  I can be thoroughly scrambled and even though it is a linear puzzle, it is quite hard to solve.

Shift Happens is a meshing-gear puzzle in the same vein as Pentafold and Gear Fold. Bram Cohen wanted a set of six gears with an unequal number of teeth. After some discussion, he proposed the numbers 10-20-16-12-18-15.

The original idea was to have the gears in a triangle, but the gear set would not mesh that way. The alternative was a hexagonal pattern. As Pentafold and Gear Fold are rather floppy due to their hinges, Shift Happens uses a shifting mechanism similar to Gear Shift, but flat instead of spatial.

It is a totally fun puzzle to play and will definitely keep your brain active. You can purchase the Shift Happens at Puzzle Master.
