About this Product
Another one of Jos Bergmans' great 4x4x4 puzzle cubes. This one requires rotations and has a great surprise ending. Even though I have previously solved this puzzle, it still took me a good 20 minutes to refind the solution. If you haven't done this one before, I would allow considerably longer.
Presented in the new larger 4.0 cm open format.
