Fun

This is probably one of my favorite puzzles of all time. You'll notice that there are many people (in these reviews and elsewhere) who note that they "got the solution but sometimes it doesn't work." Or alternatively "I got the solution because I have a different puzzle which works the same way." To those people: I encourage you to go back and when you have the puzzle apart, see if you can figure out why it "sometimes sticks" or why your normal solution sometimes "doesn't work". There is more than one step to this puzzle, and the one-step "solution" is just that sometimes the pieces align in just the right way to allow it to work. Try doing the puzzle on a very smooth surface and don't drop it. You'll probably find that you can't get it to open with your current solution; figure that out! If you know how this puzzle works, it comes apart perfectly every time without sticking in the slightest. This should take you at least an hour to solve if you're going to get it 100% right. Always remember the rule with Hanayama puzzles: it should take no force to open it. If it seems like it's stuck, you're probably not doing it right.

I figured there is only one way this could work... and I had it open in 10 seconds after ripping it out of the package. Disappointing as a puzzle. Fortunately it looks nice sitting on my desk.

This is the second one (after Cast Quartet) which I solved several times by chance and then I saw a video with the real/shorter/more logical solution. All I have to say is that this puzzle is TERRIFIC! Too bad I was not so cautious in physics classes.

I solved this preety quick because I also have the wooden X puzzle which is solved the same way. Overall an excelent puzzle.

This puzzle is fun. remember: inertia

Opened it in about ten seconds by shaking it and found that the east needle was stuck inside. fixed the needle by banging it on carpet. solved in one min after that. just place it a t a nice angle and slightly turn the loose parts

Centripetal force.

Can be brute-forced curiously enough.

omg friend showed me this puzzle. Solved it in a day during physics lecture and it was amazing. It makes alot of sense once you open it, its freaking great.

Fun puzzle. It just opened by accident and easy to figure out after that.

This one is quite clever, but it is also too obvious that you need some special trick to unlock it. BTW, the solution videos I have watched on youtube are unnecessarily complicated. There's a way to reduce the procedure by 50%.

Pretty object. Solve it in a couple of hour. It's vicious.

I like this puzzle its was clever, but I solved it in 30 minutes after getting it. I'd like to point out though i've been messing with puzzles most my life. The reason i'm rating it 3 is because I think the difficulty is mislabeled, it should be 1 or maybe 2 lower not top tier. With its rating I thought i'd be spending at least a few hours on it. Good luck :)

I got this one for my 19 th birthday, suprisingly i took it apart in 2 minutes, a half hour later i figured how it works... now i can take it apart in less ten 10 seconds, good engineered but to easy for me...

only by accident did they separate. It took some more time to figure out what I did and then it all made sense - because I knew "what" it was.....

Aaarghh. I normally like puzzles with pieces you can move around so this one needed more of my concentration than normal. The most bizarre thing is, is that after 10 minutes it just came apart on it's own. I put it back together and have been unable to figure out how to take it apart since. Haha. It's a great test of ones willpower. My second fave puzzle only to the enigma.

one of my favorite puzzles. it was the first hanayama one i tried. took about 5 or 6 hours to figure it out. the trick itself is very simple and i thought of it in the first 5 minutes. everyone who has solved the puzzle or will eventually can understand where the 5-6 hours came from... all tho i have seen people done it in less than 5 minutes i think it is just pure luck... enjoy :)

Great puzzle... The solution is quite unusual, it really makes you think out of the box. A child probably has no chance of solving it, unless by a happy accident. It took me less than 5 min to solve it, though. Actually, I once had solved this kind of a puzzle on a technical interview for an IT position. After monkeying around with it for 20 min, I was given a hint, after which the solution shortly followed. I am not going to share this hint with you here, though ;) And yeah, as you might have guessed, I got that job :)

I love this one even though I was only stumped for 15 minutes or so. I found "the secret" to devilish improvement from puzzles of the past. Mine was very well made, and can be reliably separated and rejoined. In fact it is the solid construction that pushes this not-so-difficult puzzle to a 5 star rating.

I agree with Rob below. This is is a clever idea for a puzzle but they are not made well and don't work like they should. at least mine doesn't. (I didn't get it from puzzlemaster BTW). I happened to solve it in 5 mins, but friends who also approached it correctly could not solve it, because the innards of the thing are built cheaply and don't work properly (on mine). Get a cast quartet instead.

I love the method for the opening of this puzzle. Unfortunately, it just doesn't always "work." What stinks is that when someone actually figures out how to do it and tries the correct method a few times, it just doesn't always work and they assume that the correct method is not the method. I don't think this is made as well as I'd like to see this puzzle made. There is a more expensive puzzle which uses the same method and it is amazingly made. I don't want to say any more and reveal anything.

i really love this one! its level MAX! and like Level 0 from all! totally UNIQUE! even i already open it from my friend! i still get one to collect!

I purchased all 6 of the level 6 Hanayama puzzles and began solveing them slowly at first, however this one proved a little more interesting. Though I knew the solution, the application was different. I enjoyed this particular puzzle and my co-workers are also entertained by it. I highly recommend this as well as all puzzles as great party and work conversation pieces and frustateing humor, though for those who have a little more difficulty solveing them. Thank you very much Puzzle Masters for the oppurtunity and enjoyment of your site.

I was really excited to get this one, but I solved it in less than 5 minutes. For a being the highest level of difficulty, it really let me down. The best part is watching other people try at it. I don't want to give anything away, but it was the easiest puzzle I've done from this set.

I didn't like this one as much as chain or quartet. That's because for me the solution was not intuitive. I expected a button to be hidden on the face of the puzzle,but not so.This one was maddening for a few weeks then I was playing with it, and it literally came apart in my hands!!! Half-heartedly recommended, but it's a stumper...

WOW. This one drove me absolutely crazy for months! I'd pick it up and fool around with it but I just couldn't figure it out. Then one day out of the blue I had a crazy idea and it worked! This is definitely my favorite cast puzzle, a must own.

This started an obsession for me. I now own around 25 metal puzzles. I opened this puzzle and engraved a message on the inside for my girlfriend. It took her two days to open it. Still the best and still my favorite puzzle...Get one now!

I solved this one in a unique way from the official solution. (Comment has been changed to omit the solution to the puzzle) Very ingenious puzzle.

I solved this in under 5 minutes with no hints but I guess I was lucky.

After reading all the great reviews, I was excited to take a crack at this one. Unfortunately, the one I purchased had a piece missing from the mechanism that made it pretty easy to solve, so who knows if I could have figured it out! Hopefully I can get a refund (I didn't buy through puzzlemaster).

This puzzle was very frustrating to me and no one at my school could figure it out either. (which is quite funny because they were a bunch of brainiacs then one day it just fell apart in my hands then i realized how to open it very creative and for me getting it open is just sheer luck.

Brilliant and fantastic. Truely unique solution. simple and elegant and well... WOW...

Clever and unique solution. I liked this. Quite demanding.......

This puzzle really was terrific. It was Very unique, and hard to solve. Though once you figure it out you feel so stupid at how easy it is to actually get the pieces apart!

This puzzel is brilliant, it really gets you thinking - frustrating at times - but brilliant all the same. I was fortunate enough to have all but abandoned it when a collegue moved it from my desk when it literally came apart in his hands. It was only then I could see the solution. You are well aware of the principle required to open it but are constantly stumped when it just wont open !! One of my favourite puzzles.

This is one of my favorite puzzles. Not only because it is one that took me more than 24 hrs to solve (there's few I can't solve in under an hour), but also because of the sheer elegance of the solution. You already know the principle required to solve it from grade school - but what's maddening is that even if you unlock the one piece, the other one locks. There's no way to see what's inside - you have to think about what's going on inside.
