Assembled puzzle in hand.
A tricky two-piece puzzle invented by Tom Jolly. Tom receives a share of the profits in the sales of this puzzle. Made from 1cm cubes, the completed puzzle is a 4cm cube.
The puzzle pieces are hollow but have "extra thick" 1.5mm walls for greater stiffness. This prevents "illegal moves" that can be done by flexing the pieces.
The most difficult task is putting this puzzle together, and unfortunately it will come unassembled. Somewhat easier, but still tricky, is taking it apart.
