Cast O'Gear: Hanayama Mechanical Puzzle of the Week Review

Cast O'Gear  comes from Oskar van Deventer. I bought Oskar's first version of this which was all plastic made by George Miller.

The object is to swivel the piece inside the cube, then turn the big piece over to another face.

Keep doing this until you find the exit.

Naturally, I had to buy the metal version too.  

Brilliant concept.
