Product Info

Note: Our level rating system is different than Hanayama's.  Hanayama's level 1 is equivalent to our level 5.... level 6 is equivalent to our level 10.

Four pieces of the same shape are loosely interlocked together to make up this puzzle.  All of the pieces fit loosely and it seems as though they would be easy to take apart.  However, one is soon at a loss, as the puzzle give no hint about how it is solved.  The trick is to not think too hard, but to ease your mind as you take up the challenge.  The American Bram Cohen designed this puzzle. 

The theme is loose.

A very nice puzzle but which is finally far easier than expected! The thing I appreciated the most was the impossible object look of it you discover by fiddling and is not obvious at first look. It is a good hanayama puzzle but it was a bit deceptive because this puzzle won an honorable price at IPP design competition and it was not as amazing as I was hoping it to be.

Lots of fun. Difficulty rating seems right to me. The falling-apart quality is great, almost to the point of being funny. This one reassembles more easily than it comes apart; the reverse is the case with most puzzles. After initially solving, a little practice and study can reveal some techniques to make it easier. Dexterity is definitely a factor.

I enjoyed this puzzle more than other Hanayama puzzles of higher level. The solution is very precise and I think I managed to find it because I had already solved cast Quartet. At least to me something similar is used in the solution and the thought of it helped me solve this one.

I had to admit defeat on this one and find a youtube video demonstrating the solution. I'm not surprised I didn't solve it. It's not particularly complicated, but it's precise. The Hanayama product line always lives up to my expectations.

Al first touch it might seem that it will fell apart at any moment. But then after examining it will be revealed that how it works. Working out towards the solution is not hard, especially since yo can see the inner mechanism pretty well. Not too hard a puzzle, but definitely worth buying.

First I really had to examine this how it works, but when you get it it´s fast to open. Many of my friends have not even got it open. Not bad puzzle.

Very nice puzzle which may take you 5 minutes to 1 hour. The harder you try with this one, the more it resists! A logical approach (thinking about it) works better ...
