This game delighted my twelve year old, who taught it to dozens of other children at a living history event on Fourth of July. So nice to have a good wooden one that will stand up to hard use.

This beautiful puzzle makes a great desk toy. I love that every time it's like a new challenge.

This puzzle was extremely satisfying to complete and remarkably simple actually in its final execution. I was expecting some jaw dropping idea to be the solution, but it actually looks like common-sense when it’s finished. Warning-The 4 hour play time is misleading if you’re just an average joe like me. It took me at least a week of tinkering an hour or more each day, and really I would chalk my success up to trial/error and luck. There are just so many ways to do it wrong, it’s staggering. Cheers and good luck on this one puzzlers! You can do it with some patience and staying motivated!

We decided to try solving a puzzle every month as a household challenge and this subscription has it all, with great puzzles that are very challenging and fun to have around.

Wife loves the challenge - she will probably solve them all and move to the next level.

Buyfriend loves it and thinks it's a very cool puzzle. We do try to surprise each other whenever we can and I feel this puzzle did the job... He still hasn't solved it.

Nicely made, will definitely be handed down in my family. Sons are enjoying it

Very detailed puzzle with a high level of complexity

This is well made and simple. Thank you!

I love how simple the solution is, yet it is cleverly designed, making it a perfect addition to my puzzle collection.

This is a great mechanical puzzle. I really like the challenge and how the puzzle is built, which makes sense once you solve the internal mechanism.

I spent several hours trying to crack this puzzle and eventually used 3D modeling software just to understand what was happening inside. The complexity is remarkable, with countless looping paths and no obvious dead ends.

I gifted this to my son who is a Mechanical Engineer, and he loved it.

They look the same but have completely different solutions and are not so hard to solve, with the haaa moment coming in the form of the varied dovetail mechanism.

Love those kinds of puzzles. They make you really think, and it's so satisfying to play with. One day I'll solve it:)
