Product Description

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.

True bonds has always been hard to form, but once formed such bonds are eternal and hard to break. My original version was created with this image in mind, but the puzzle was completed into a cast puzzle with a bond that is truly difficult to unravel. How would you go about breaking and forming this bond? There are two approaches to this puzzle and I challenge you to both! The key word is "Bond."

Thinking that Iw as purchasing the Hanayama Cast Coil (easier than tis one), I ended up purchasing this one. First, let me state that it intentionally doesn't come apart easily, like some of the other metal puzzles, allowing you to reverse engineer the solution. Second, once you have it apart, good luck ever getting it back together. I tried for over 4 days, playing with different techniques, assemblages, etc., but never got close. Sadly, my wife thought that my frustration level was too high, and threw this one away. :( So, I'll go on other's reviews to tell me how great this one is/was. For me, it's merely a fond memory.

Interesting design, but not one of my favorites. After finally getting it apart, I cannot get it back together.

While some report this being easy, it has been very difficult for me. I have played with it on and off for months and it is still together. I have it so twisted that I cannot even get back to the start. Don't think of this as a bad thing, I have trouble fining puzzles that take a long time to figure out. The only negative I see is the smaller size make it a little difficult to work with, but don't let that stop you from trying it.

Had apart in 20 min., reassembly,! another 20. I love a good challenge, looking forward to many more.

A lot of eye candy when you realize you can make a large square out of the two parts once you disassemble it. It took me a year to get it back together. Toughest one out there save for News, which I think is an unfair puzzler.

This thing is pure work of art! It has few states, assembled it to second state (which looks extremely cool) so easily and just out of nowhere. Was very surprised to find this solution and extremely pleased with the puzzle! Great!

Great puzzle. Love the starting shape. Solved it within 30 minutes from mindless tinkering. Although, putting it back together is the hard part

Finally got it back together after a year of tinkering with it. Without a doubt the most difficult Hanayama puzzle I have ever solved.

The puzzle is very well made, and is quite a challenge. Not for the faint of heart.

it's a great puzzle, i managed to solve it four times (disassemble & reassemble), but i still have some hard time learning exactly the solution... thank you for this very very cool puzzle!

This is my most favourite Hanayama cast puzzle (at least for now from the ones I got)! I could write a novel for me and it. I just managed to solve it completely - the second form that could be created from the four parts is so logical! And assembling and disassembling the first form (shown on the screenshot above) is indeed very hard. I still have difficulties putting it back together. Summing it up: a GREAT puzzle!

I really enjoy this puzzle. I've had it for 3 days, and I've been playing with it off and on. I got the pieces apart in about 20 minutes, purely by chance. Now I'm trying to reassemble them using logic. It's a tough puzzle that should keep seasoned puzzlers entertained for hours. Highly recommended!

Wow this is by far the hardest one of the Hanayama puzzles that I have tried but also great and cool to look at.

this thing is a MARVEL. It feals beautiful in the hand, It looks wonderful. Solid weight and build. and is worthy of the lvl 6 difficulty. I spent over a day taking it apart. and had to cheat to get it back together. I d not see this being the type of puzzel to share, or bring to an event.the difficulty crosses the "too hard" boundry. I am looking at another couple days before I can actualy figure out how I got it apart and back together. the 2ndary assembled form is pretty cool.

I'm not usually into puzzles but i got this one for birthday so i gave it a try and i loved it. This is really amazing puzzle. It took me days to disassemble it and when I got it apart i couldn't put it back together. this is not one of those puzzles where if you got them apart you know how to put them together. It took me even longer to assemble it than it took to take apart. Great puzzle!

Not really fond of this one. The only way you can do this without cheating is just by luck pulling the pieces in the right direction. Not really a puzzle, just trying lots of times.

I was actually able to undo this puzzle in 20 minutes. I was so into it that I even forgot how long I spent on it. I love it, difficult, fun, elegant, and the construction itself is not too complex. In my opinion a good puzzle has few peices yet is very difficult to solve. This is a must have.

this is my most favorite puzzle. It is truly difficult to take apart and put back together. It also has a very sleek design and looks very cool. I'd recommend this puzzle to anyone really seeking a challenging puzzle.

This is the hardest puzzle i have ever solved. It took me around 1h to put it apart, then about 15 min to put it to alternative assembly-method. The hardest part was to put it back again to original starting point. After 4h during 3 days, I put it on the shelf and forgot about it. I tried 3 more times, but finally i put it back after around 4 months after disassembling it took me another 4 hours. It has two ways of disasembling it (maybe more), I put it apart with one, and assembled it again in second way.

Are you kidding? I have got to the point where the whole thing looks like Hiroshima! I can't get them apart, nor put it back together! This is a really frustrating puzzle! A must-have!

this puzzle's great--rather tricky and probably the most elegant of the 3-D disentanglement/disassembly puzzles I've seen. definitely give it a shot.

If there was a 11 Stars rating, this surely would be the winner - for frustration! Oh sure, fiddling around with it in front of TV, it literally fell apart and hour or two later. But that wasn't even near the half-way point. Consider it an introduction! There are multiple solutions. Multiple dead-ends. And you're faced with dilemma of turning the large square back into the two links... In hindsight should have paid attention during disassembly. After several extremely frustrating nights working through commercials and even the whole movie, still got nowhere. By 5am resorted to youtube, but the pieces kept binding and refused to give up, driving me insane. But in the end, when placed in the exact correct positions, the pieces do indeed seem to melt together or flow apart. Truly beautiful. PS: Definition of insanity is repeating actions expecting different result. If claiming insanity in criminal case, can use video footage of attempt to put Quartet together as evidence.

There's something really elegant about the clean look of this puzzle. It looks equally cool when together and apart in four pieces. This one took me many hours to complete. As others have said, taking it apart is tricky but reasonable. However, getting it back together is where the frustration really begins. There was one moment where I could swear I had to force it more than I should have, but sure enough, that's how it worked. Even after solving this one, I have doubts that I could easily do it again. I'm almost afraid to take it apart again! One of my favorite puzzles.

Really great puzzle! It's pitty that i solved it in about 10 min. but it took me longer than the other hanayama puzzles. Usually I slove one in 5 min., but this one was really fun!

Fine puzzle ! Really hard to put back together.

This is one of those great puzzles that is more challenging to put together than to break.(pay attention when dis-assembling!!) The pictures provided don't show that there are two assembled versions. The two linked squares, or one large square. I have 5&6 star Hanayamas that I've solved in hours or even minutes, but this one has had me stumped for days. Good value for diehard puzzlers.
