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

First things first, this puzzle says "these pieces have a secret: each time their arrangement is changed when recreating the original shape, the solution changes." This is mostly false. It's true that the pieces can be put together in different ways, however the solution is the same no matter how they are assembled. It might *technically* be different, but not in any meaningful way. In terms of build quality: This is a great piece. It looks good, fees heavy and strong. Mine came slightly scuffed up, but it's very minimal to the point where you wouldn't notice unless you were examining the finish of the pieces. The puzzle is smooth and built to last. In terms of the puzzle: This is my first ever puzzle of this type, so I wanted to start strong with a difficult challenge. That's why I bought this puzzle, it is rated 6 of 6. I was able to take this puzzle apart and put it back together within 20 minutes. I'm a little disappointed because I was expecting it to take me an hour or more, but maybe my expectations were set too high. I wish I hadn't read the puzzle's theme before attempting to solve it, as the theme served as a one-word hint which made the puzzle a little easier. The theme is given on one of the paper inserts describing the puzzle that comes with the packaging. I found this puzzle on Puzzle Master and they give it a 9/10 difficulty rating, so if you are looking for the hardest Hanayama cast puzzle I suggest you try the hourglass puzzle. That one gets a 10/10 difficulty rating and is a common result I found when searching online for the most difficult Hanayama puzzle. I can't personally attest to its difficulty, however I liked this square puzzle enough that I've already purchased the hourglass puzzle. At around $10, this isn't a bad deal. You'll get at least 30 minutes of enjoyment and a cool puzzle to toy around with and show to friends. Overall, I'm satisfied with this puzzle though I do with it were more challenging.

Very well made of quality materials. Heavy for its size which adds to the fun. My incredibly smart wife has yet to solve it. Which she insists is a good thing since she finds these types of puzzles intriguing but often too simple to solve.

All Hanayama puzzles are of excellent build quality, this one is downright pretty. Mirror polished two-tone finish. Having a collection of MANY Hanayama puzzles, I notice sometimes the "Difficulty Level" is deceiving. Personally I would rate this one a level 4. This does not compare in challenge to other level 6 puzzles, but it still might be worth the buy. I solved this fast but still happy I bought it. It looks very simple, and it kindof is... but it's also TRICKY. If you're new to Hanayama this is a good one. If you've got a collection and conquered other level 6 puzzles, you might solve this fast like i did. Either way it's a very nice one to display after you've solved it. To better test your puzzling skills: "Padlock" is fun and difficult, one of my favorites. "CHAIN" another fave, is tough, simple, but clever. "Quartet" and "Hourglass" are extreme small parts manipulation challenges : ) ~Have fun

It really is a unique device, fits in the palm and is hard but perplexing to figure out simply because there is not very many moving parts. It is a cool nick-nack which can be figured if held for some time and dimensions understood. The metal is a nice material which has faint engravings throughout its body, if I recall correctly.. Enjoy this if these masterful brain busters are your collection or forte. Very interesting to understand the dynamics of this physical object combined together which lasso reality in challenging ways, though not undermined of natural dimensions. Believe it to be a chain hanging loosely upon the open lock over our world. Twist and turn to reveal the simplicity which greatness of freedom lives upon. When you first pick this one up it appears that all the pieces are identical but in reality they are not - they are actually 2 pairs of identically shaped pieces and within each pair 1 piece has the maker's name stamped and the other has Quartet stamped on it. Initial attempts rapidly lead to the conclusion that this is not going to be a quickie! One movement is possible on either of the pairs (one easily and one with more difficulty) and after this you meet a dead end! At this point it dawned on me that being systematic may be important - I decided to try each of these movements with the other pieces starting in different positions. I decided to try each of these movements with the other pieces starting in different positions but now moving in different directions! Many things are possible and they all seem to end up more or less with the same impasse! At some point during this laborious trawl through multiple orientations and directions I managed to get 2 pieces rotated, progress 8) Again I could go no further and this time I struggled to put it back the way it came! So far I had been at it for about a week (not continuously, you dope! I do eat and drink and unfortunately have to work! about 3 or 4 hours in total). Just try not to drop it around

Not sure I would rate this one's difficulty at level 6, which is supposed to be the hardest puzzles they make. That being said, it was fun to do decipher and it also makes a great fidget toy once you figure out the solution. All of the Hanayama products are extremely well made with exacting tolerances. I have gotten pretty much every one that is available on Amazon and I have not had an issue with any of them being slightly off on the dimensions which then breaks the puzzle.

well made. Easy to solve, difficult to reassemble.

Bought several puzzles by the company. Good coffee table items for guests. They look so artistic that several parents told their children not to touch them as they thought it was for decoration only. Very durable quality. Suggestion: get an easy puzzle or two to go with the hard ones for the kids to not feel stumped.

My husband does these puzzles all the time but this one was by far the hardest for him. It was a good challenge that he enjoyed.

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

Interesante y entretenido juego en nivel 6

Es dificil de resolver y muy entretenido. La calidad del metal es optimo y no se maltrata con facilidad.

Ainda vou resolver, mas parece promissor.

My son loves these puzzles. I got him some level 6s for Christmas and he is still working on them. I find them a little pricey but they are solid construction and do keep these young adults entertained. Good thing they have a leaflet w all of the models offered.... I cross them off as time goes on, so I don't buy the same ones again.
