The Mortal is a Labyrinth game reserved for the experts. This is the final, punishing puzzle in Inside3's ZERO series and wow is it difficult. If the prospect of a dynamic, complicated puzzle that changes orientation and has blind corners wasn't enough - what about if there was no map (normally found on the Zero series embossed in to the side) and you couldn't take it apart? Once you move your puzzle ball from it's entry chamber, you run the risk of never seeing it again.

The Inside3 Series of Cube Labyrinths are some of the most cleverly designed toys we've come across.
