Improved Cam Box – Eric Fuller

Whelp, I caved in and bought another puzzle box. After feeling super excited about solving Topless Box, I decided to splurge again on Eric’s next offering – Improved Cam Box. My wallet is in trouble though because the next 3 months releases all have more boxes – Escalating Box, Secret Agent Puzzle Box, and Death Box. Oh My, that’s a lot of boxes to come!

Improved Cam Box is beautifully constructed of African Mahogany with a Black Limba top and bottom. It looks amazing and the construction is a masterclass in precision woodworking. The dark streaks in the Black Limba provide a striking contrast to the overall appearance of the box.

Beautifully precise construction makes this box special.

Straight off the bat, there aren’t too many clues as to how to open this thing. The construction is such that it appears that the sides will possibly slide up and down and the top and bottom both have a peculiar and distinct line cut into them. Otherwise, there is nothing outward to give away the secrets. There are no loose parts inside, no rattling pieces and the puzzle feels largely hollow. Time to investigate further.

The sides do in fact slide a bit, but only a little bit. I am able to slide one of the sides maybe a quarter inch, which then allows the top (or is it bottom?) to slide another bit, which then allows to the other side to slide a small bit. All these bits don’t add up to much however as they neither unlock the puzzler nor reveal any additional clues. The one thing that has my scratching my head is the purpose of a magnet that is revealed after sliding the side down (or is it up?) Why is this magnet here? What purpose does it server? And what do I do next?

The sides slide up to reveal a smallish visible magnet. But, what does it do?

And I’m thoroughly stumped. I can make the above movements happen, but after that there is nothing to do. I’ve repeated the steps forward and back, over and over, and still no realization about how to move forward. It’s at this point that I think I need to stop and analyze things. Why is this called the “cam” box. What is a cam exactly? I have a background in rock climbing, and to me, a cam is a device that sticks into the cracks in rocks and as a force is applied, the “cams” push out into the rocks. As more force is applied, the cams push harder into the rock, thus providing anchor points in an otherwise anchor-less crack. But, how does that apply to this puzzle… hmmm…

I spent another few frustrating sessions working on this box to no avail. And then, one evening I tried a new move that I hadn’t thought of before. (Isn’t this always the way?) And sure enough, I had a solution. Curiously, although I could repeat the process, I still wasn’t sure what the mechanism was or how it really worked.

Puzzle solved! Box Opened!

It wasn’t until many days later, after thinking about things for a while that I really understood what was going on (and the purpose of the magnet). I have to say that this is a very clever puzzle box! The thing I really appreciate is the subtle misdirection that is happening. I won’t say any more, but there is a reason why the particular move took me so long to try. Very clever indeed! One has to be very observant to solve these puzzle boxes! Which is another reason they take me a while – I tend to fiddle more than I tend to observe.
