The puzzle is a set similar to the
Penultimate Burr with
multiple problems to be solved. The set consists of a 4×4×4 cage with a
2×2 opening on each face and 14 non-planar penta/tetracubes. The
objective is to fill the cage with four of the pentacubes and three
tetracubes to complete a 4×4 cube. A jig is provided for testing
possible solutions outside the cage, as well as a box which doubles as a
display plinth for the solved puzzle. This is a difficult puzzle, with
two assemblies having a unique sixteen move solution!
