Puzzle was at first just a big fidget toy. After a couple days of twisting and pulling, randomly I was able to remove the pin. The insides are not whats expected. Have fun with it and enjoy the suprize when it finally clicks all together for ya.

I had already solved an older wood copy of Harun, but I was happy to see CD release it again so I could have my own. It's a great size; I appreciate these smaller builds since they take up less shelf space. The metal pieces are a pleasure to manipulate and not too heavy either. Watching these pieces slide into the box is so satisfying. Keep up the great work!

This puzzle is huge, bigger than the standard puzzle hamster! Having everything visible does not make this thing any easier. This is a lovely puzzle box made of lots of acrylic, and opening the box requires guiding the ball in the fully visible maze. Moving the ball around initially was fairly easy, since it was clear where to go. But then it gets complicated fast, and the various sliders to manipulate the maze add to the challenge. It was fun to try to slowly map out where to go, but I still ended up having to do this in sessions.

Aha Box is a fun trick box that will leave you puzzled until it reveals its secrets. Sturdy construction that will hold up to your non-puzzling friends and the fit and finish is excellent.

I have the original metal one by Wil Strijbos, and it's great. This CD version adds on top of the basic puzzle with their signature tolerances, wood choices and perfect finish. A real joy to play, and the magnets are VERY appreciated, coming from someone who has seen several people pick up my metal one and watched it all tumble out into pieces on the floor!

This is a beautiful little box. It's not the most difficult box to figure out but still very enjoyable. The he look and finish are top notch. This is a great addition to anyone's collection.

I'm more of a puzzle box guy but every once and a while I run across metal puzzle(s) that interest me and the Slump Cube, like the Impossible Dovetail trio is one of them. I like this one and someday I may even figure out how to reassemble it!

This puzzle is awesome! With multiple unique steps to get you to the solution, it takes a good amount of time and some creative thought to figure it out! That being said, the puzzle is challenging without feeling unsolvable, and each step that brings you closer to the final solution is all the motivation you need to keep going. Plus, this puzzle is very aesthetically pleasing. Just be careful while solving, because at a certain step some tiny pieces can fall out. I know from experience! :)

This puzzle has a beautiful presentation, it is not easy to solve, but the solution is very elegant. I recommend it 100%.

Wow! I must admit, this might be one of the coolest puzzle locks that I own. The solution is super rewarding when you get there.

If you’re looking for a fun sequential discovery puzzle, this one is great!

The book covers a wide history and geography of puzzles, laid out in an informative, conversational style. The author's love of puzzles is definitely apparent.

I was super excited to get the Eric Fuller sticker with my purchase this month. Eric was a 5 star guy through and through.

If you’re looking for a puzzle that is not only challenging but beautiful at the same time, this is it! With so many different types of wood and the precision that allows each piece to fit together, it becomes more that a puzzle. It’s a piece of art!

I’ve just recently gotten into puzzles and I must say this is a great puzzle box for someone new and seasoned. Quality was top notch, the solution was clever and I can’t wait to introduce it to some of my friends.
