Dick Gives Me Think 5 Things To Think About

Window Lock 4 by Dick Hensel

A few weeks ago I received an email from Richard Hensel, informing me that he was completing a batch of his latest wooden locks and suggesting that I might like to avail myself of the opportunity to look and feel stupid (my words not his). 

Having just paid for and received, over the last month or so, quite a large number of rather lovely puzzles (including the Stickman Midas Touch Box, the Angel's Wheel, Idan's I Need My Lunch, the latest releases from Mine and of course the large delivery from Jakub), I figured that discretion was probably a good idea and I asked Dick to wait for a new month before I bought and received yet another toy that would make "she who makes the world shake in fear" angry. I think it worked in that when it arrived, there was just a little muttering and no noisy shouting or pain in the back of my head.

This is the fourth in the series (obvious from the name I guess) and looks fun. It shares the family resemblance with an oak lock and acrylic window on the front allowing the whole thing to be seen. But seeing is not understanding as I was about to find out. I set straight to work after I had finished work yesterday (I missed an MPP yet again). As the title of the blog post says - this puzzle gave me 5 learning/thinking points:

1. Always take your photo before starting to play - I couldn't resist fiddling and managed to make things happen that I couldn't get out of and then I realised that I might not be able to take my initial photo.
2. Look at the damn thing properly before doing anything - it might help you plan what you can do and it might help explain why certain things move/change/happen.
3. Think© - stuff happens or doesn't happen for a reason!
4. Don't stick your fingers inside small holes - stuff can move and then you are in real trouble!
5. Dick is a sneaky bastard!

Having finally gotten back to the beginning, I took my start position photo and started again. needless to say I didn't really understand what I had done. Time to start afresh.

The first thing to notice is that on the left hand side of the lock (as with several of these in the past) can slide and it moves an obvious piece inside:

One edge sides and moves "stuff" inside

Ball bearing present

Having realised the obvious, I couldn't see how that would help. The slider is all very interesting, but it doesn't seem to engage with anything and after a few seconds of opening and closing it several times in various positions, I came to the conclusion that there was more to this puzzle than that. as you can tell, my level of genius is well below that of Derek. I gradually realised that there must be something else hidden inside that I needed to find. Memory of several previous Window Locks left me the feeling that there should be a ball bearing somewhere to help use manipulate internal parts. Rotating the puzzle from side to side, I could hear something rolling about but it couldn't be seen. I turned it over to look at the back and then when I had it right side up the ball bearing was visible. I had no idea where it came from! The BB could be moved around most of the right hand side of the lock where it did absolutely nothing. At this point, I obeyed the thing I learned in point 2 above - LOOK! 

It is relatively obvious what is locking the shackle in place but not what is stopping the locking mechanism from moving. I did find a channel or two for the BB and in one of them I promptly lost it. It went in and didn't want to come out again. There was a tantalising view of it peaking below part of the mechanism but it didn't want to return to the play area. Bugger! I am rubbish at puzzles! I figured that this must have been where it was when I first picked it up so I had better do the same thing again to get it out as I had initially. Except I didn't really know what it was. After 5 minutes of fiddling I eventually figured that out and I could make the ball disappear and reappear at will. Phew! I couldn't make it do anything but at least I had it where I could use it. 

I used learning point 2 and 3 again to decide where I could place the BB to try and manipulate the interior. There is a rather subtle feature that is easy to miss but if you notice it and do something then there is a click and something changes. I had no idea what had changed but the click was quite obvious. To me a click was very useful - all of a sudden, I could move the BB somewhere else and all sorts of stuff inside slid around and BINGO! The lock was open:

Solved it! No spoiler here

I had it open and was able to see the mechanism that had revealed itself. Very clever! But that's not all of it. We are now onto learning point 5 - Dick IS a sneaky bastard. Whilst I understood the last part of the unlocking mechanism, it didn't mean that I understood the puzzle. I was able to return the pieces inside to the initial configuration and the shackle was closed. BUT, when I tilted the lock, it spontaneously opened again. I had missed the critical part of the mechanism. The click had changed something and I didn't know what it was. I could put everything back but it wasn't actually locked.

At this point, I decided that maybe I had a couple of pieces in the wrong order of positioning (if you have opened it, then you know what I mean). I tried to change the order and gravity wouldn't do it. Time to put one of my fingers inside through a small hole to hold things in place whilst I used gravity. Here we arrive upon learning point 4 - I managed to rotate one piece that should not have rotated and then it fell out. Aaaargh! After a short panic, I managed to put it back and then rotate it into the correct position so that it wasn't going to fall out again. At this point I heard a clatter and had a race with a cat. Yes, the ball bearing had fallen out! Luckily I intercepted the ball before it was actually swallowed. I reckon a trip to the vet might have cost me my life - "she" doesn't know about that aspect of this puzzle and I'd be grateful if none of you told her.

Well, that wasn't terribly bright!

Having returned all of the innards to the lock, I was completely stumped. I could open and close the lock so that it looked like I had solved and reset it but I could not re-lock it. I was obviously misunderstanding a fundamental feature of the mechanism. Taking time to think© again. I tried to work out why the locked position wasn't holding properly and I had my lovely little Aha! moment. I could see part of what was happening and if I tried a specific manoeuvre then maybe...click! Oh yes! That click is absolutely crucial. Once I finally realised what the click had been, I was able to lock and unlock the puzzle at will. Fabulous!

Allard's review said that he took a couple of days to work it out and agreed about the sneaky aspect. Everyone can agree on learning point 5 - "sneaky bastard"!

If you get a chance to play with or buy this puzzle then jump at the chance. It really is a lovely design with not quite everything on show but enough to work out what is required. My set is now up to 4 of them now and I'm already looking forward to a future one. I still have one of Dick's locks that predates the Window locks - it has been sitting on my desk for years now and I have no idea how to open it!
