Brian’s Big Baffling Bolt

Bolt: 65mm x 30mm, Brass
Box: 110mm x 50mm x 40mm, Papua New Guinean Ebony
I finally got done solving Brian’s Big Baffling Bolt (BBBB) from Brian Young of Mr. Puzzle and… just… wow! Mr. Puzzle announced the puzzle some months back and when my turn eventually came after several more months, I jumped on the chance to try Brian’s newest SD creation, following up on the interesting and uniquely broad challenges of Abraham’s Well.

In creating numerous, highly regarded SD puzzles, Brian has played with brass bolts in the past, having incorporating them into wooden designs: Three Wise Bolts, which I am fortunate enough to own, as well as his contribution to the amazing Lewis Carroll Project, Tweedledum and Tweedledee, which I was fortunate enough to try (but not fully solve) at the Puzzle Palace. This newest puzzle is meant as an homage to his 30 years of puzzlemaking, incorporating “hints” of tricks from some past designs in new ways, alongside novel mechanisms. Despite having solved several of his puzzles, I have to say that I did not recognize anything in particular, so I am not certain from whence these came but I do appreciate the sentiment: a cool way to share tricks that are now difficult to access due to the rarity of so many of his past SD designs.

BBBB consists of a rather massive brass bolt along with a lovely wooden puzzle box made of Papua New Guinean Ebony. The box has slots on either side, a hole on the bottom (alongside the Mr. Puzzle logo) and a resting place atop fitted to the bolt. The bolt has a washer along with two nuts (each with a hole), one of which spins freely without screwing in either direction. I was able to make a bit of progress rather quickly, always a fun start and one which belies the difficulty to come.
This bolt was by far the trickiest bolt I’ve ever seen, with secrets galore. Through starts and stops, I worked my way through multiple aha!’s – so much so that if this puzzle consisted only of the bolt, I would have been satisfied with it as a solid puzzle (according to Allard’s blog, this was initially the case). But no! – there is a puzzle box as well, one that integrates well with the bolt before the finale may be reached. The end reveals a “30th anniversary plaque with [a] pearl” so it is quite clear that you’ve finally solved the puzzle.
I must admit that I needed more than a little help to get through some of BBBB’s multitude of aha!’s and tricky moments, in particular to get through some of the final steps; this did not take away from the experience in any way – the aha!’s keep coming and things I was sure wouldn’t do much worked in interesting ways. Some steps are a matter of exploring everything you have to be sure you know what everything can do, as you discover multiple tools to help along the way. I found myself exclaiming in surprise more than once as unexpected turns occurred, finally breaking through to the end in a final sequence that kept on giving after I was sure I was reaching the end.


The puzzle does not require hitting, spinning, or any force at all. Everything works smoothly; more than that, at one point I knew what needed to be done and was sure it would be difficult to accomplish. I found myself getting a bit disappointed, thinking getting through a section would require stabler hands than mine, only to realize that Brian had foreseen this and incorporated help into the design, such that this was its own aha! moment, in addition to the joys of discovering its mechanisms and tools. Although there is a bit that is somewhat blind, you are provided with sufficient information (if you take your time) to get through.
Despite it having taken me several weeks to solve (and in addition to my terrible memory), it was not difficult to reset: you will have come to fully understand, if not always see, everything such that you know what to do. After putting everything back where it goes and marveling at my own brilliance, I went back through the solve one more time, appreciating the rhythm and flow from section to section, refining my understanding of one section in particular as I worked back through.
BBBB is still being produced by Mr. Puzzle, with a promise that he “will definitely make more of these puzzles in the future.” If you do go to their site to contact them, be sure to browse the site as they have some great puzzles, including a number of IPP designs and the very unique Abraham’s Well (and an excellent Black Friday Sale going on now – no, I get nothing from the plug, I just think it’s a great site from a great puzzlemaker). Be warned that the site is closing towards the end of December, with Brian going into retirement (I do not know how this might affect the production of BBBB unfortunately). Hopefully we will still see puzzles coming out from time to time, as most certainly appreciate his work!
