Wil Strijbos’ Revenge Lock, aka The Wanderer

Emails from Wil about the release of a new puzzle are always cause for excitement and generally result in a response of “Hit me up!” almost seconds later… the announcement of his new puzzle lock in the style of Gary Foshee’s well-known Lunatic Lock was no different… I was never going to pass up on getting it, and Wil made sure that the serial number matched most of my other recent Strijbos treasures – I am 002 – licenced to ponder…

“The Wanderer” is a further development on his earlier “Revenge Lock” produced many years ago to reprise the Lunatic lock and confound puzzlers: it looks pretty similar to the Lunatic Lock but the internals are somewhat more challenging…

Now I’d been fortunate enough to see an early prototype of “The Wanderer” over a year ago at Wil’s place – Louis had been test-solving and advising and there was a new prototype so we all had at it… Louis had followed the text-book solve and I’d tried a few slightly less orthodox approaches and was somewhat amazed when one of them paid dividends and I was able to open the prototype… sadly news of my success reached the puzzle designer (at the other side of the room!) and he decided that a thorough redesign was in order… and when I next saw it, it had grown a casing and I was assured that the internals had been thoroughly re-jigged to stop me solving it “my way”… 

Right, so get the puzzle home and explore.

First impressions – it's beautifully made and it looks like a lovely lump of aluminium (No, gentle reader, that "i" is not superfluous!), with a little brass and steel to make it look like a lock… 

Wil’s instructions are to first find your serial number, then open the shackle and remove the key (a brass bolt in the centre of the lock) and finally, release the wanderer, before returning everything back to its starting state. 

The first step effectively involves releasing the lock from the casing as the serial number is on the back of the lock… that’s not too challenging and shouldn’t take a puzzlist particularly long…

Your next step is to open the shackle – that is a significantly harder step in the process… one that took me weeks! 

And thereby hangs a salutary tail, dear reader… you see, it was my own fault entirely – having seen the prototype, I knew what I was planning to do to solve this lock, and as soon as I’d separated the lock from the casing, I went off down a particular path that I’d pre-planned… only to find it wouldn’t do what I wanted it to do. 

I then spent many, many evenings trying to prove the Einstein quote wrong and indeed extract a different outcome from trying the same things over and over again… just in a different order, or in a different orientation, or while in the shower – you get the idea. 

Eventually I was getting goaded by news of my friends all solving theirs and how great this puzzle was – and I had a pretty lump of aluminium for all I knew…

…until someone made me think (c) a little, and I found something I really hadn’t expected – and it was entirely my own fault – because I “knew” what I was trying to do, I ignored a bunch of possibilities and didn’t look for some things I really should have – most of all, because one of those little things was stopping me from doing what I wanted to do…

Going back to basics helped me spot something interesting which turned into a fantastic “A-Ha!” moment – one I had totally overlooked and I had been thoroughly underestimating this puzzle – and I paid the price – for several weeks!

Moving on from there was an utter joy – not only was there a wonderful discovery, but there was so much more to explore now… and that changed everything… and about an hour later I had extracted the key and the shackle, retrieved the wanderer and had a neat little pile of pieces on my desk…

So I did the obvious thing and sent Wil a picture of the bits – he replied pointing out I was halfway there now… Uh-oh…

Next evening I sat down with the bits and attempted reassembly – for several hours… along the way learning an awful lot about the mechanics inside, and just how devious they are – there are plenty of ways to put this thing together wrongly, but none of them will allow you put the lock back in the case with everything immobilised as it is in the start-position… time and time again I’d try a series of things only to find myself blocked and having to go back to the start again… reassembly is tough – and you can see everything and it’s pretty clear where it all has to go… yet…

By the end of that journey I’d found little ways of making some of the process simpler, more predictable, and importantly for me, less reliant on dexterity, until I finally managed to get it all back in the casing, neatly locked up.

This is a pretty darn amazing little puzzle – even if you haven’t had the “advantage” of seeing the prototype, this thing will confound and entertain – there is some beautifully hidden engineering in there that will surprise you and a wonderfully simple, reliable mechanism to lock it all up – several times I thought I’d damaged something or bent something and that things weren’t behaving properly, only to realise I hadn’t quite understood something or not got it quite right… you have to do everything properly or you don’t progress… nobody is going to manage to fluke this one like I fluked the prototype – this is a well-thought-out, beautifully executed puzzle… instantly one of my favourite Strijbos puzzles!

A cool cultural reference and the puzzle’s goal encapsulated in a simple name – Pac(k)Man is another neat little aluminium puzzle from Gary Foshee’s workshop. It comes in one of his customary purple velvet drawstring bags and it’s most definitely pocket-sized.

In its unsolved state it has a large screw-head protruding outside of the little aluminium cube and you’re told that your goal is to get everything either inside the cube or at least flush with the sides. The projecting screw-head is nicely knurled, making it pretty easy to unscrew it with just your digits. There’s an obvious place to put this screw, except that it’s pretty clear that there’s something blocking the hole so the screw can’t get all the way home, leaving it projecting a bit.

Well it was never going to be that simple, was it?!

OK, so what else have we got? Well there’s another screw in there, but it’s flush with the surface and unless you have Chris’ weird fingers, you’re going to need a tool to get that one out… it needs a hex wrench… but you don’t seem to have one… examining things a bit more and you’ll see that there’s an exit hole for what appears to be the goodie partially blocking the screw hole you want to use for the big screw…except it’s being held in place by that flush little hex-headed screw… so where is that hex tool?

Depending on how you approach these things it might only take you a couple of seconds, or it may take quite a while, but when you find it you’ll grin a bit… that lets you make a little more progress but pretty soon you’ll find yourself stumped again – and I really loved this second little brick wall that you hit – you think it’s all plain sailing from there only to find another road-block that requires an altogether different approach to problem-solving!

Great little puzzle!

[In answer to the inevitable question: privately – they haven’t been generally available for many years!]

Classic Foshee!

Ring Box was Gary Foshee's IPP29 exchange puzzle. 

It is a classic Foshee puzzle!

Beautifully machined in aluminium, the Ring Box resemble a sub-C battery – just about the same size with a little button on one end. It arrives in a pretty little purple velvet drawstring bag with a folded piece of paper clipped to the drawstring that says “SOLUTION” on the outside. Clearly this is meant for amateurs! People who might actually resort to peaking at the solution… Perish the thought!

The first time I came across this little beauty was at a Dutch Cube Day in Eindhoven… Nigel had picked up a copy from someone and he was handing it around to annoy people… he succeeded on me and I managed to get absolutely nowhere – so I knew I needed to pick up a copy of my own at some point… and one finally came across my path recently.

This time I managed to spend a little quality time with it and solved it reasonably quickly and it has become an instant favourite. At first, the only interesting thing it will do is allow you to press the sprung button… over and over again… with not a lot of result. Examine things a bit more carefully and you might notice something interesting… but then you’ll probably hit a wall…

If there are some helpful puzzlers nearby, they might even ask if you’ve tried spinning it or blowing on it… but once you find its simple little secret (and grin broadly at Gary's impish sense of humour) you will be able to retrieve the brass ring safely hidden inside the Ring Box.

Brilliant bit of humour wrapped in a lovely puzzle.
