The idea for the Escalating Box came from a couple different mechanisms I'd been fooling around with. I was going to release them as two fairly simple separate boxes, but realized that I could put them both into one trickier box. I made a poll on our Facebook Group and everyone overwhelmingly voted for a single, more difficult box. Done and done!

I got to the drawing board and realized not only could I put both mechanisms together, but that they would interact making the sum more difficult than the parts. Finally, just for fun, I added a third tricky lock before the final release move. Be careful what you ask for, facebook friends!

This is a fun solve, about medium in difficulty, and one that rewards progressive solving and manipulative experimentation. Construction is beautifully realized with a Curly maple box and several exotic wood options for the lid.

Challenging and worth the price.

I dont mind paying more for puzzles that take time and have quality. This puzzle is cool. I would fiddle with it while I watched reruns of Seinfeld. There were a few moments of surprise. I like it a lot. The quality, of course is top notch. Keep up the good work.

Excellent combination of multiple mechanisms

This box is very well crafted and nice to look at, especially with the Bocote lids, but also great fun to solve. It starts off easy with some moves that are not uncommon to Eric's boxes, and then quickly gets more complicated. Some parts of the mechanisms give visual clues about how to solve them, but then there are other parts making strange sounds and giving various feedback to the solver. A great combination of mechanisms not too easy, but it can be solved, and probably my favourite of the recent box releases.


This box is suitable for beginners to explore the use of gravity and sound to switch. For me, this box has a place that I was initially confused, that is, the two sides of the board (short side) are movable. How is the way of the long side of the box fixed?

Gorgeous and very fun

Title says it all. The woods used are stunning, and how can you not love a multi step box? Having so many tricks up its sleeve makes this one you must have in your collection.

Finally Solved a Fuller!

Yet again, he has brought us an excellent box with which to play. Excellent make - Perhaps not as difficult as Topless or Cam (I say this because I still haven’t solved them lol).

As always, this is a puzzle box well worth buying!
