Cast Cage is a medium difficulty puzzle. It is not particularly intimidating, and a puzzle others will want to “try”; especially if they’ve just seen someone else solve it. Like many puzzles of this type it is much more of a challenge to remove the star than to replace it. Obviously the star must be in the right position to get out and it will come out of only one opening. It is also obvious that it cannot exit via either hole in the ends of the cage. Other than that, you’re on your own.
The other two reviewers have made comments that this product is not as strong as most puzzles in the Hanayama series. They claim the cage is not made of cast metal. I can’t comment on that. The puzzle I have is made by another manufacturer, Noese,and is all cast metal and silver colored rather than bronze, and certainly heavy, and strong, as is usual with Hanayama.
It will stand up to lots of use and provide much entertainment without breaking. For an additional challenge, once you have solved this puzzle, is to attempt to do it blindfolded or without looking at it.
