Packing puzzle designed by mathematician John Conway and made by Tom Lensch in multiple exotic woods.

Excellent challenge, and sizable enough to be a fine coffee table puzzle. Minor damage to frame; see second photo.From Pluredro:This puzzle was designed in 1998 and Juno made only one at the time. Although the configuration of the puzzle looks relatively simple, it is very time consuming to produce the puzzle giving reasonable detail and finish, thus we believe not so many puzzles were produced in the past even by the second party. The puzzle has several challenges, making an 8 x 8 squa...

Dr. Volker Latussek wrote about it:“I have been thinking and working on FERMAT for more than two years. I had initially planned a puzzle with a box typical for me: a square base and centred opening and three triangles. Preferably equilateral triangles. Despite considerable effort, I could not find discover an exciting solution. So I switched to isosceles triangles, in the end the 45 degree angle imposed itself. The side lengths of the three triangles now had to be chosen in such a way that the...

"The Improved One Piece Packing Puzzle seems impossible. Based on Simon Nightingale’s concept, the goal is to put the square cube in the box. Easier said than done; strong magnets push it back out no matter which face you try. What next?"This puzzle is extremely satisfying to solve and even to play with. This puzzle should not be stored in the solved state as Eric has stated that this may cause the puzzle to break down over time.

The solution is quite difficult to find!For multiple items, combined shipping is available.

An inexperienced puzzler will stumble upon the solution eventually, but the sharp eye will find a clue in design that leads to the solution much quicker. Mr. Trevor Wood designed and manufactured this ...
