BePuzzled | Quartet Hanayama Metal Brainteaser Puzzle Mensa Rated Level 6, for Ages 12 and Up

Good quality! Husband cracked it really fast though, in spite of being a harder one. Small in size. Looks as described. No instructions, because obviously that would defeat the purpose.

Super Brain Game: This Puzzle is a real challenge! It took my husband (a software engineer who loves puzzles) about 3 weeks to figure out. It's rated level 6 by Mensa, so it's tough but fun. If you like puzzles that make you think, this one's for you! Strong and Durable: This puzzle is really well-made. It's made of metal and feels solid. You can play with it a lot without it breaking. Fun for Everyone: Whether you're playing alone or with friends, this puzzle is a blast. It's a great way to have fun and test your brainpower. Overall, I'd say it's a winner!

Don't watch video if you want to solve it yourself. Very difficult and fun! This is the most difficult puzzle I've solved. Had a really fun time with it, the first 10minutes it felt impossible. I didn't time myself but it probably took me an hour of play time to solve it and I'm by no means a good puzzle solver. Mastering it took probably another 30mins, I can now take it apart and back together under a minute. Was good times, highly recommend if you like solving puzzles. Don't watch video if you want to solve it yourself.

This is a well made puzzle and feels good in the hand with no sharp edges.. however, the nuts did get jammed up on the threads while I was finessing it. I had to whack it with a wrench to get the nut loose. Overall it was fairly satisfying if not too tough puzzle.

Hard to solve! Exactly what I wanted!!

My review is a response to what many have described as their biggest gripe with this puzzle: I understand frustration. I also know that my strength becomes hulk like when pitted against a tiny adversary that won’t give up easily. Hard won experience has taught me the proper approach to take when tackling a difficult nut and bolt situation. Most of the time, a gentle hand is all the strength needed to thread Nuts on Bolts. And guess what has happened when I have taken the “I’m bigger than you!” tact when a bolt doesn’t want to screw on? Yea, that’s right. I’ve know the definition of cross-threaded when I was four. This puzzle was created to teach people, who otherwise would have never been exposed to the handyman life, how easy easy it is to cross-thread a nut and bolt. I’ve solved one or two of these Hanayama puzzles, and my biggest takeaway is the solution never requires strength. (Think about the physique of a typical puzzle-solver, and the stupidity of creating a puzzle that requires the user be able to bench their own weight) <— not gonna happen! If after the casting process, when the threads are cut (I suspect on a CNC) they used stricter tolerance, the puzzle wouldn’t be as susceptible to cross-threading. Why they don’t do that is a mystery to me. The only guess I have is for cost reduction. The same could be said for the nut size in relation to the bolt. I suspect the solvability isn’t changed either way if the nut and bolt fit wasn’t as sloppy. So yea… this thing is cool, and I’d buy it again. I was able to solve it in about ten minutes. Maybe I got lucky. Scratch that. I’m not going to lie to you. I got lucky. I’m kind of a halfwit, and if I were you, I’d ignore everything I’ve written here. And if you’re still reading this, then the joke’s on you buddy!! Ha!

I totally dig this puzzle. No, I haven't successfully undone it but it's still fun. I also love the sound of the clicks and feel of it, it's heavy and smooth if you're an ASMR kind of person. I did cheat and YouTube the solution but I think a bird flew by and I'm easily distracted so...

This is a tricky puzzle, but once you get the hang of it you try to solve it faster.

Ainda vou resolver, mas parece promissor.

Complicado de uma forma simbólica, porque você pode deduzir os movimentos corretos por uma abordagem mais observadora e "filosófica", senão você fica apenas em tentativa e erro e isso seria uma abordagem bastante demorada, imatura e desnecessária.

Despite my initial concerns when I started playing with this it is actually good quality. This will make more sense once you've solved the puzzle. I actually solved this accidentally. So that was awkward.

Hasta ahora es el que más he tardado en resolver, el mecanismo y la solución es tan original que al final, todo el puzzle tiene sentido. Hago una amplia recomendación a este puzzle de hanayama, no es nada fácil y parece no tener solución, ya con algo de análisis vas encontrando el camino correcto, en fin solo les puedo decir que es una especie de laberinto que no puedes ver, si no solo sentirlo al giro de sus partes. 10 en originalidad, calidad y diseño. Puzzle nivel 6 de 6. Until now it is the one that has taken me the longest time to solve, the mechanism and the solution is so original. I highly recommend this hanayama puzzle, it's not easy at all and there seems to be no solution, but with a little of analysis you'll find the right path, I can only tell you that it's a kind of labyrinth that you can't see, just feel it at the turn of its parts. 10 in originality, quality and design. Puzzle level 6 of 6.
