One of Wil Strijbos’ recent emails contained a couple of new puzzles: a new variant of an impossible dovetail joint and a blue box that sort-of resembled a tardis from Doctor Who – called First Box.
First Box as you might expect from the name was the first puzzle box that Wil designed many moons ago. When I visited Wil last year, he'd pointed out a black and aluminium box on one of the puzzle shelves that housed several other Strijbos originals and he'd mentioned that it was his first puzzle box and that he was hoping to have some produced in the future. He wanted to give me a shot at it, but sadly whoever had played with it last hadn't locked it up properly, so it was placed back on the shelf...
Since then Wil has taken the opportunity to improve on the design (read: make it harder!) and has also found a neat solution to an aspect that concerned him about the original version. The original came with a separate tool - which bothered Wil a bit - so he toyed with the idea of not including it and suggesting that puzzlers make a trip to their local hardware store and buy whatever tool they thought might be useful to get into the box - however recurring nightmares of puzzlers merrily heading off to their local ironmonger and purchasing a large hammer stopped him from trying that. So the new design dispenses with the external tool... :-)

My copy arrived literally days after I’d ordered it and first impressions were that this was a really heavy little puzzle – it’s very clearly not a box with a lot of space inside it … which probably means that it has a lot of gubbins inside there making sure that it stays locked closed. The lid has very little play in it to start with and has a large nut screwed into the top of it. The front of the box has Wil’s signature and a production number in the bottom right hand corner. There’s a small dark hole in the middle of the back of the box and a hole in the bottom that lets you see a small steel cylinder – which Wil has helpfully told us we are to get out of the box – although rather unhelpfully, that hole in the bottom of the box is too small to allow the cylinder out…
OK, so you have a seemingly impenetrable blue anodised box – you can see the lid has a little bit of play in it – there’s one obvious thing to try, so you do, and that’s not spectacularly useful, so you think for a while and explore a few more avenues before finding what one might loosely call “some tools”. Trying out various things with the tools you’ve discovered leads to some further discoveries – among them that sometimes the lid of the box feels a bit looser, sometimes there is a pin across that hole in the base, and sometimes there’s a pin across another hole.

Wil’s helpfully told us in his email that there are no magnets and that no bashing is required – yet I suspect that most folks will be tempted to try that, if only a little every now and then…
During the course of your explorations you can start piecing together some of what must be going on inside there – part of the clues come from the sounds inside when you tilt the box this way and that – but the confusing thing is that those sounds don’t always appear to behave the same way! [Pixies!]
Add in the interaction of the tilting with the use of those tools and there is more than enough to try and keep track of – and if I’m honest – the first time I opened the box there was more luck than skill involved and I ended up spending a long time examining the innards to work out what I was doing… and then even longer to work out why my method actually works! (There’s something a little disturbing about finding a method that works absolutely reliably- but realising that theoretically it really shouldn’t work …and it took me a couple of days to work that one out!)
This is a really good little sequential discovery puzzle – the tools are nicely hidden; the internal mechanism makes it virtually impossible to fluke a solution – the machining is really superb so everything fits beautifully (and slides around like steel on wet ice) … but once you’ve worked it out, everything is totally predictable – definitely a well-behaved puzzle – doesn’t leave anything to chance and doesn’t let you do anything you can’t undo … although I realise that until you’ve opened it, you might disagree with one or both of those wild allegations!
