I have been wondering if anyone ever made the Cannon and Ball Puzzle from Professor Hoffmann’s book Puzzles Old and New. I am so glad I found it here. I am planning to get one for every puzzle lover in my family, which is everyone except my loving wife :) They are going to love it.

I’m certain that the person receiving this for Christmas will really enjoy it.

This is the second kit we have gotten from Kubiya and it has become our favorite project for our kids, ages 10 and 12.

This puzzle will make the perfect gift for my puzzle-loving partner.

Can't wait for my son to find it in his stocking from Santa and enjoy it!

I keep it on my desk at work and everyone in my office loves it. Just got a few more for the family to play with at Christmas.

My husband loves to solve those puzzles, and he's always looking for the hard ones - I think I found it :)

It’s really tricky and makes you think all the time. I solved it a couple of times but every time you connect 2 M’s together you have to think again how to solve it.

I love mechanical wood, math and jigsaw puzzles. This box is the best gift I have received in a long time. I am so excited for the next box to arrive.

Can't wait to give it as a gift!

I really did not expect such a high quality product though I knew it would be great. It will be fun to watch my brother battle with it for Christmas.

The Cannon Puzzle is now one of my favorite puzzles to display on my desk at work, and I just got five more to give to friends and colleagues. I know they will love it as much as I do.

A very nice game, similar to checkers but it makes you think outside the box. The board is beautiful and looks great on our game shelf.

These puzzles look very simple, but they are actually super difficult. You may convince yourself they are not possible to solve. I am going to give them to family and friends to see how they do.

I finally solved the Boltrix puzzle after two months of working on it. Now I’ve mastered it and can screw the nut to the bolt and reset it.
