Project Genius Constantin Waiter's Tray Wooden Puzzle – Unique Brainteaser for Ages 14+, Enhances Problem-Solving, Ideal Gift for Puzzle & Wine Lovers

Like another reviewer, my puzzle came without a critical slot in one of the pieces which has rendered it unsolvable. (The wooden piece on the right). But on the bright side, I’ve enjoyed beating my head against this puzzle for over two years—not realizing it was unwinnable. It was only because the screw backings came loose enough that it nearly came apart that I finally looked up for images of how it’s *supposed* to look. And that’s when I notice the manufacturing flaw. So, for anyone purchasing the puzzle: be sure to doublecheck that all the correct slots are present before giving this as a gift.

It took me about an hour to solve but once you get the pattern, it's so exciting to start moving everything with purpose. Once you solve it, it takes maybe 5-10 minutes to reset it and do the pattern in reverse. The only sad part is now the secret is ruined and it's not as fun to play again, but fun to watch others try!

Great puzzle. Once you figure out the pattern, its easy to solve. But, that doesn’t make it any less fun. The two step forward one step back pattern is satisfying. About an hour to complete. Overall nice.

I bought this for my husband for his birthday- while it is a little smaller than I expected, it’s a beautiful puzzle and makes for a great decorative conversation piece.It took my husband a little over an hour to solve and a half hour to put back together. I was able to solve it in just under an hour, but it took about an hour and a half to put it back together (you’re more likely to accidentally solve it again than get it back to starting)!Our family were all pretty captivated by it as well- everyone wanted to fidget it with while visiting and loved how it looked!I highly recommend this for anyone who loves a good puzzle!

This puzzle is ver nice, it would make a great gift. It is a very high quality product. Nice weight, high quality wood, acrylic and metal connectors. Smooth to glide and slide moving pieces. The color finishes on the different bottles are also nice. I don’t think it is difficult to solve, just fiddling and frustrating. But, once you solve it you get a great feeling of satisfaction.

Great puzzle. I bought it for my 13 year old son who recently got hooked on all kinds of different puzzles. This one challenged him but was not unsolvable for him. Eventually everyone in the family tried it and was challenged. I recommend it for 10 and up.

Was a birthday present for my brother he solved it in 20 minutes but he is really good at puzzles very sturdy the gift box was a little broken but the puzzle was in good shape and looks good as an arsty piece

Would like it to made with a little thicker wood and to have the bottles slide more smoothly
