Triple Yolk
Lewis Evans
EGG!!!
@loderman & the MPD
There is something about egg-shaped puzzles that is just fun: Unstable Eggs by CoreMods (reviewed by me here), several eggs by Stephen Chin (including the very cool take-apart puzzle, Ze Tomago), Akio Kamei’s Egg, Rik van Grol’s Egg Balance series, and the many, many, many other egg-shaped puzzles out there (ok, that may be most of them, but those are some fun puzzles).

And now, the ultimate egg (and all-around great) puzzle: Triple Yolk (TY) by Lewis Evans. TY is a sequential discovery take-apart puzzle that relies on a good amount of sequential movement to accomplish its goals (this is how I would categorize it anyway). Amazingly, this complex, challenging, and well-crafted puzzle is his first to be brought to the puzzling public! His skills as a professional product prototyper are on full display: the puzzle is plastic, but this is not the filament of 3d prints. Rather, you will find that it is smooth to the touch, with none of the inconsistencies in even the best PLA prints. At approximately 3″ at its widest point and 3.5″ tall, this is more akin to an ostrich egg than your typical chicken-based puzzle eggs.

TY’s goal is to remove the three yolks – of course, we initially have no way to know what exactly this means, but it is ever so obvious once they have been found. First impressions are very positive: his attention to detail is evident in the professional packaging with a perfectly molded rubbery plasticy base surrounding the puzzle inside the box. Picking it up, its weight belies the internal complexities of the design; you find yourself able to freely rotate the uppermost sections (not a spoiler – it’s readily apparent when picking it up). The movements are wonderfully smooth – neither loose nor tight and sliding around easily and intentionally. TY makes a bit of noise, giving you an early idea of some of the internal mechanisms that will only make sense upon further close observation.

The first yolk is discovered fairly quickly; an early win that gives you no sense of the legitimately difficult challenges that follow. This is by no means an easy puzzle, and will require your full attention if you hope to solve it. There are some really neat things that happen as you move through the solution, and plenty to discover and experiment with as you struggle to determine what’s what. A fair amount of the process is semi-blind, requiring close observation to make sense of what is happening; there is ample feedback to allow you to slowly develop an understanding of what is going on inside, in addition to the well-planned glimpses inside that help develop this mental map (again, this is apparent from looking at it, so no spoilers).
I hit a big wall towards the end of the puzzle – from what I can tell, this is not an uncommon experience. As with any good puzzle, when that aha finally hit, it was a major puzzle rush. There were plenty of aha moments that preceded these final discoveries, and the final steps are especially satisfying.

Suffice it to say, this is a great puzzle. Lewis takes every opportunity to display his commitment to puzzlers’ enjoyment, happy to help should you get stuck or encounter any issues (it was discovered that fully re-inserting the second yolk could lead to a bit of an issue and Lewis responded quickly and thoroughly, mailing out aesthetically-consistent, pro-grade cards with a nice warning, following up on his email to all those who has obtained a copy – I personally fell prey to this genius move and Lewis even mailed out a tool that I could use to get myself back on track – a seriously considerate and generous act).
There are only 50 copies of Triple Yolk (mine is #8) and the price was reasonably set at a place that reflects the complexity of the design and its production; it wasn’t cheap by any means but it was completely worth every penny and I haven’t heard any complaints from any of the other puzzlers who landed a copy.
Now we must eagerly await Lewis’s eventual follow-up: no pressure 😉
