The puzzle is to remove the four pieces from inside the box.
Tadao Muroi (since deceased) designed this framed burr in Japan in the early 1990s and it is with the kind permission of his son we are allowed to make this puzzle. The puzzle requires twelve sliding moves to remove the pieces from inside the box. The real puzzle may turn out to be how to get them back inside the box again using these 12 moves, although there are other combinations.
The puzzle was given a difficulty level of 7/10. We really think that if you can master this one in a couple of hours you’re doing very well.
