- Cylinder Hanayama Metal Brainteaser Puzzle Mensa Rated Level 4, for Ages 12 and Up

I absolutely love this mind game puzzle! It’s both challenging and engaging, keeping me entertained for hours. The design is clever, with intricate pieces that fit together perfectly, and the quality is outstanding. Each level of the puzzle offers a unique challenge, making it fun to solve progressively. I’ve found it to be a great way to unwind and exercise my brain at the same time. It’s perfect for both solo play and group challenges. If you enjoy puzzles that make you think outside the box, I highly recommend this one! It’s a fantastic addition to my collection.

This puzzle toy is a challenge but in reverse. Yes, it takes a while to solve but it takes EONS to reassemble and for that I would grade it at a level 6 difficulty. But we survived and so will you. It is very well made and sturdy. Definitely of good quality. The directions were intentionally vague. We are already looking into purchasing our next one. This would make a great gift to either make or break someone's confidence.

Took husband about 10 minutes to take apart but an hour to put back together.

Fun to fidget with but I was never able to solve it until I read another review suggesting to get out the lubricant and once I gave it a spritz with the WD-40, I was able to get it apart in about five minutes. It seems less of a solving puzzle with a logical solution than just a trial and error to puzzle that will eventually come apart from playing with enough times the right way and it comes apart. Still like fiddling with while watching TV or on the train etc but not sure there's much thought needed to solve it

This has been my favorite puzzle yet. I own quite a few hanayama puzzles and have loved them all (despite wanting to throw some of them at the wall out of frustration), but this one takes the cake. Despite what others have said, it’s not all luck. With some attention to detail, you can figure out how it works and solve it. However, it’s not for beginners. It’s quite meticulous and precise, and it took me about an hour of continual effort to crack it. So I would say the rating is true, it’s a 4 out of 6. It’s well constructed, has a good weight to it, and is just a lot of fun and satisfying to solve. 10/10 recommend this puzzle.

Gifted my father this who doesn’t like or want anything and loves building making things. He used it immediately and silently played with it. For perfectly in your hand easy to bring and perfect for grown ups and teens. Good material that doesn’t break quick.

The puzzle is amazing, both in craft and in playability. The puzzle's solution was well enough to figure out, and it kept me engaged to solve it for quite some time. Even after I had memorized how to solve it, I have been playing with it to keep my hands busy and engaged as I would wait, or think, or watch. The puzzle is very sturdy in craft. As per the company's clarification, the puzzle is made from a zinc-metal alloy. It's weighty as well, which in my opinion, gives it more value in the importance and mystery of the puzzle. Hanayama has a plethora of amazing puzzles to choose from. This puzzle is a testament to Hanayama's amazing quality and design. If you wish to buy a puzzle from Hanayama, I would say this is a specific puzzle to invest into.

At first I thought I would never solve this one, until I figured out it's just like any combination Master lock. When I opened the box I could feel it was a solid puzzle. Again Hanayama made a solid, die cast puzzle. This one took me about four hours to solve once I figured out how to approach it. Even after solving it, I still need to take my time to solve it again. Unlike the Padlock, Donuts, or even the Dial, you cannot see where the line up is. It's all trial and error. This is a great introductory puzzle from Hanayama. I would recommend this as one of the first puzzles you purchase.

I love these type of puzzles. I own several Hanayama Puzzles, and they have never been disappointing. Always High Quality, Beautifully Designed, Wonderfully Polished, and Hyperbolically reviewed. I can't wait to order another one...

This is a beautifully constructed puzzle, it's solid metal with a decent weight to it. Even if you can't solve it, the spinning pieces feel good to manipulate. As for the challenge, it's quite tough given you cannot ever physically see how the puzzle is being solved. There's a lot of feel work involved as you rotate it around like you would cracking into a safe. Definitely challenging putting it back together as well, as the solution can come quite rapidly, leaving you a bit stumped over the correct order. Great puzzle. Looking forward to checking out more!

Finally solved it! Took me a few hours spread over many many days.....solved it.....and reassembled it as well. Well spent money.

Generalmente prefiero los hanayamas en que puedes ver lo que estas intentando para resolverlo, en este, todo es a ciegas hasta que lo desarmas puedes entender lo que pasa adentro. Pero realmente me gustó este modelo, es mejor que el Padlock en mi opinion. Para facilitar mientras buscaba resloverlo use una cinta para marcarlo, en lo que haces prueba y error es de gran ayuda.

Gifted it to my niece, he loved it!
