Up, Damned Spot; Up, I say! PLOD by Joe Guarini

PLOD

Jo Guarini

A few months back, I was offered the chance to try a new puzzle by Joe Guarini (@jhoag), designer of Detective Box (and co-designer of some forthcoming designs from PI Puzzles, his puzzle partnership with Ross Feinstein, who is also known as our friendly discord-neighborhood @cryptosutra – they’ve got Bricked Lock coming soon, a 15 step puzzle lock that looks very cool). Obviously, I was happy for the opportunity (this post would otherwise be rather short and pointless, one of which might be strange for this blog) and I soon received a 3.25″ acrylic cube with a black rubber ball roughly the size of a racquetball ball (I debated whether that was redundant before going for it). At the bottom of said ball was a white dot, which must somehow be made to be stably pointing up for the puzzle to be solved.

Picking it up, it was immediately clear that this ball did not want to flip over for longer than a second or two; no matter what I did, the ball would just roll itself back, white dot down. And I did a great many things: I had a whole lot of ideas to try, one of which I thought must lead to a solution (it didn’t). I found myself caught in a feedback loop – that sense of “just one more try” had me staring intently at the uncooperative ball for quite some time, Happy Gilmore-ing that little b@$t@rd as if I could intimidate it into compliance.

The beauty of this puzzle is that it really lends itself to some of that thinking stuff I hear puzzlers talk about. After handling the ball for a while, I had developed some ideas of how it might work. Joe and I were chatting throughout the process, his initial curiosity turning into amusement (and perhaps, I imagine, a bit of pity) as I threw out increasingly strange ideas as to what was going on inside the thing. A few of those ideas might make for a decent puzzle, but none made the puzzle I was holding.

There were a few other puzzlers that had been given a copy to try (at least two of which I know managed to solve it) and Joe had decided that it made sense to use a smaller acrylic cube to contain the ball, and he generously (and sympathetically) sent out another version: same sized ball nestled in a cozier cubic compartment of 2″, same cruel and unyielding white dot laughing at me from below. Aha!, I thought, surely this was a clue as to what tricks could work in this smaller space, surely this would make the solution a bit more in reach for this dim-witted puzzler. Alas, while the first thought might be true, the second was not true enough to allow me to actually solve it unassisted.

As days turned into weeks turned into months (my puzzle passion generally outpaces my skill) and my ideas grew increasingly bizarre, I finally began asking Joe for some rather straightforward guidance; I would like to say that I truly figured it out on my own with just the help of his hints, but in all honesty I think he pretty much had to eventually spoon-feed it to me lol. Regardless, I was finally able to master that damn dot, which now stares upward, the laugher having become the laughee (sure, I stand there laughing maniacally in triumph at my defeated puzzles, so what? I don’t come into your house and judge what you do, do I? After all, people who live in glass houses shouldn’t throw stones…. people in glass houses probably shouldn’t throw much of anything, I guess… then again, people who live near people who live in glass houses should maybe try minding their own damn business…).

I turned a ball upside down! Glad I am finally putting all those student loans to good use…

The trick hidden within this seemingly simple puzzle, this ball in a box, is quite ingenious. I can imagine Joe getting the idea and laughing at its devious originality; it is not something that I think would occur to most people as it employs (as far as I know) a truly unique mechanism. Knowing the solution, I was able to solve the puzzle, which is one of its strongest features: a solution that is quite elegant and relatively easily repeated, yet elusive enough that it poses a challenge (to me, at least). The puzzle is so original, in fact, that categorizing it seems like a circularly fruitless enterprise, one that would likely lead to a questionably accurate spoiler, at best, while still being arguably incomplete, if not straight-up wrong.

Joe is still producing these, so find him on Discord if you are interested in trying one (@jhoag). And if you are able to solve it more easily than I, good on you – no need to share such information with me: please remember what I said about glass houses (which is to say, go live in a glass house and throw stones, jerk).
