Very difficult. Not a good one to share with friends, because you know for sure that there is no chance for them to solve it quickly

I spent a few hours on it, handed it to a friend at work who took it apart within 5 minutes but now i can't get it back together!!! He is currently stumped on the Cast Elk puzzle which I was able to figure out. Just goes to show that peoples brains work differently.

This is truly Hanayama's hardest puzzle. It took me a week and a few quick looks at the solution to complete it, but it was very worthy. Even after removing the first piece, the remaining two would still make a decent 2-star puzzle (on Hanayama-scale). It looks quite average compared to the usually well-decorated Hanayamas, but the challenge it offers is unparalelled. The solution is so long, that it did not fit on one page (like any other Hanayama I know of), so it's quite difficult to learn. All in all, it's a must-have for any serious puzzler.

I never got the puzzle apart on my own, but my daughter disassembled it in 40 minutes. Nonetheless, it looks almost as though it had been designed by an alien intelligence. It is sleek, slick and mesmerizing with an interior logic all its own. It refuses to come apart easily...you must do it the right way.

Awesome puzzle!! A lot of fun to solve! Took me just over two hours to solve it and a about an hour to solve it back. This was my first hanayama puzzle. I was afraid that it would be too hard and maybe i should start with a lesser difficulty puzzle. But i was wrong. Didn't really take me that long to solve. So i would say that it should be around 8-9 level. All in all, quite a fun puzzle!!

It took me 5 minutes to take it apart and a little more to bring it back again. Vortex and Aqua are way more "Boggling" than this. It is a great puzzle compared to others, but the difficulty it's overrated, that's why i give this rating. (if you get the solutions first, you should be ashamed of yourself, and you shouldn't waste you'r precious time! )

This puzzle is just too much of a mess. Sure, it's hard and rewarding, but it's just not that fun. It seems like a complete cluster.

Great puzzle! I was a bit afraid of it after reading that it was by far the hardest of the Hanayamas, but I think it is of comparable difficulty to Equa, Vortex, News and Quartet, at least for me. I like it because the available moves seem fairly straightforward, but you gradually discover additional things that will progress you further than before, until you finally solve it. Quite satisfying.

Very nice puzzle. Took over 3 hours to disjoin and about an hour to assemble back. Perfect for killing time :)

I got my husband 3 level 10 puzzles for Christmas. He solved the 2 wire metal puzzles instantly, so those were a let down, but this one took him about 2 hours (two 1hr periods about 8hrs apart, although he says he was thinking about it a lot in that 8hrs). He has a gift for solving puzzles so it's quite hard to find ones that challenge him enough. I think this one had him stumped for the longest amount of time I have seen so far. I wish there were more difficult cast puzzles though, he really liked it but I would like to stump him for longer.

This is a very challanging puzzle and took me two days to get apart and back together. None of my friends can even come close to the solution. I really had to think about this one and keep track of my steps. It still amazes me that a person crafted this puzzle.

I love this puzzle. It took me many weeks to solve it. I needed a hint to solve this.

Absolutely the best ( read : most difficult) of cast puzzles. I love this. As well i like Quartet, Elk, Chain, Radix and Baroq. I just got Vortex in my hands about 1 hour ago........

davvero difficile complimenti

This puzzle was AMAZING!!! It was hard to figure out, and even after figuring this one out I still love playing with it... I guess I am easily distracted...
