Anti-Gravity BoxFrederic Boucher, 3D Packing Puzzle, 2.25″ x 2.25″ x 1.5″
A few months ago, I wrote to Frederic in the hopes that he might happen to have a few puzzles that were seemingly unavailable. Most were, but he did happen to have a last copy of Anti-Gravity Box, which I happily requested, along with a few other new puzzles that he had on hand.
March 2022 Update: CubicDissection will be releasing a new version of AGB (titled: “Anti-Gravity Box+”) in it’s upcoming March 21, 2022 release – not only will this feature the ever-awesome craftsmanship and woods CD is deservedly known for, but, according to Frederic: “This new version includes a 2nd set of pieces with a solution that includes a trick that I think has never been seen in any other design yet…” This presumably constitutes the + in CD’s AGB+. So get your clicky finger ready as I don’t expect that these will last long: (EF + FB)CD = Awesome Sauce!
I have solved several of Frederic’s puzzles in the past – 3D and 2D packing puzzles that offer a serious challenge, comparable to pieces by Osanori Yamamoto, Koichi Miura, and Volker Latussek, and featuring elements such as interlocking elements and restricted openings.
Anti-Gravity, however, adds new mechanics by introducing a number of magnets into the mix. This makes for a unique and novel puzzling experience; it is no longer “just” about finding a way to get the pieces into their frame, as the magnets throw one’s general approach out the window.
The box is a 3×2 voxel frame that features a removable, acrylic top, allowing you to easily reset the puzzle and view your progress. The box has two, single voxel openings at 90 degrees to one another; both are in the middle of the bottom level, allowing you to enter each axis, but offering no room for angles of any kind. You must fill it with 6 identical rectangular 3×1 blocks; 2 have two magnets on one side, 3 have magnets on one end, and one block has none.
There are rules, of course: you need to place it on a flat surface and you are not meant to pick it up or tilt it (of course, you may hold it while you insert other pieces); you cannot poke your finger into either of the openings to push the pieces; it goes without saying that you cannot just lift off the top and place them in. The removable top is a kind addition, as it avoids the need to struggle to remove pieces when you have eventually found you had made a mistake. The puzzle arrived with the pieces stacked neatly inside. It is kind of cool to have a puzzle so confident in its structure, that it can come fully solved without having spoiled anything.
While by no means simple, neither is it an overly difficult puzzle – in my experience, one of his other packing puzzles was more challenge than I could meet (I am admittedly not so great at packing or interlocking puzzles generally – my interest far exceeds my ability when it comes to these types of puzzles).
More importantly, this is a very fun puzzle, and one with which trial and error will not get you very far; knowing the pieces you can eventually figure your way through it.. After spending a few minutes playing with it, experimenting to get to know the pieces and what they can and can’t easily do, I had to stop and think. This led to the first big aha moment of a series of such moments, leading to the full solution. Each step is its own planned approach, each piece requires forethought once a workable order has been determined. Apparently, this has two approaches that lead to similar solutions; I have found one and will undoubtedly spend some more time to find the second.
TL;DR: Anti-Gravity Box by Frederic Boucher is an original approach to a 3D packing puzzle, with magnetic pieces needing to be stacked using entries that allow for little margin of error. While not Boucher’s hardest puzzle, each move must be planned and purposeful through thoughtful approach and not just trial and error. It features a convenient removable top to reset after you inevitably make a mistake, and is so confident in its own puzzling, that it can arrive solved without lessening its challenge.
