Hidden Passage: Wooden Puzzles for Adults - 3D Brain Teaser Interlocking Game Handmade Organic Educational Problem-Solving Game for Adults & Children. Corporate Desk Accent for Office.

This is a beautifully-crafted puzzle. It came with me on a recent family vacation, and the kids (and some of the adults!) loved it. My brother-in-law, in particular, was fascinated with it as he took it apart for the first time. It's not an easy puzzle to solve - but once you learn how to solve it, it's pretty easy to put it back together again (so that you can torture someone else with it).The included solution diagram is rather tiny and difficult to follow, but you can figure it out if you get really stuck. This is definitely one of those puzzles to leave out for visitors. It's both beautiful and fun. Well done!-- Updated --I purchased a second one for a friend a few months after I bought my first one. The instructions had been updated, and they are more detailed and clear than the original version. They are also a bit larger, aiding significantly in their clarity. Nice improvement! Well done!

Made from solid wood pieces so it looks nice as a decor item. Very difficult puzzle, but thankfully the instructions were included

Love this.! This was for my young (26 year old - he is young to me) adult son. This was part of his Christmas box. Several people enjoyed trying, ranged in ages from 14 up to 50's. This is a well made item, to withstand this family.

It's very much like the cylindrical shaped one we got, just squared. That is, the puzzles go together exactly the same way essentially, so it took my kids about 2 minutes to solve. they now have it down to under 30 seconds. This puzzle loses a star only because the pieces stuck a bit more compared to the rounded version we bought a couple weeks before. those pieces went into place much more smoothly. My kids even noticed. Otherwise a fun little puzzle. Really small so easy to leave on a desk or something. But not so small that it's tough to work on. It's about the size of a rubic's cube. My boys age 9 and 11 compete to see who can do the puzzle the fastest. less than 30 seconds is the goal.

A fun little puzzle. Very well made.

Bought this for my husband on his birthday and he had it solved within a day. But it is a great ice breaker to stump guests when they come over! Only complaint is that one of the pieces cracked, and we had to glue it back together.

This one is quite complex, and it took me a while, and a great deal of memory to manage to put it back together without looking at the instruction. Fun, fun, fun!!!

This product is amazing for when you have nothing to do. You can give it as a gift and use something sharp to engrave a message or something onto the product. It is amazing for kids and can give them a slight challenge. One down side is that one side is slightly loose. Not that it would fall apart or anything but it can slightly move around when intact.
