Locked Three Times Over!

The Vertigo Puzzlebox from Quizbrix
First up, I should let you know that this was sent to me for free for review.

In December 2022 I reviewed the aMAZEing Puzzlebox (also available from PuzzleMaster) and absolutely loved it. A few months later they released a follow up challenge called the Vertigo Puzzlebox and I had intended to buy one this time. Time went by and I got sidetracked by life, work and many many many other puzzles and it sort of fell by the wayside. The new one was reviewed by Steve (Boxes and Booze) reminding me that this was a great designer. Then, out of the blue, I was contacted again by Peleg to ask if I would be happy to review it. I cannot say no to a good designer and it duly arrived from Israel last weekend.

As with the previous puzzle, the challenge is to find and release the gold bar hidden inside the box, using only what is provided as you work through the sequence. The top of the box appears to have the letters QB on it superimposed on each other (I confess that I had to squint at it for a while to see it and thought it might be a D&G logo). The puzzle is made almost entirely using the ⅓ height lego bricks in various sizes and there are a number of voids visible and outlines of larger constructions that look like they should move as a single piece. In one place there is a clear brick and the ability to see right through.

Time to start - the only option available is to push and prod at various bits of the puzzle until you find something that moves and then you are off to the races. The first 4 moves are a nice unlocking sequence which leaves you with the lid removed and a tantalising view of the gold brick inside:

No spoilers here! I cannot reach that gold brick
Having seen the target, it is time to try and work out how to remove it. This is easier said than done. A single tool is found on the way and there appears to be a number of places that it can be used but none of those places seem to actually do anything. There are 8 possible places to use that tool and it requires careful attention to realise when one of them actually does something. after this there are more opportunities to use the tool in other places.

There is slow progress of finding things that move inside but it is not apparent what those movements actually achieve. It is an odd sensation of making progress without truly understanding that you are and only realising it when something else suddenly is possible. after the first few moves inside I hit a brick wall. I could see my target, I could move all sorts of things inside and tantalisingly the brick got closer but then it stopped. I was stuck at this point for several days. I was determined not to use the solution video they link to on their site and kept trying for the best part of a week.

After days of doing the same thing over and over again and then back tracking, I had one of my rare thoughts. What if I...Aha! I had moved a new part of the interior which I had not done before. Did this help? Well sort of except the brick still wasn't reachable. Having got to a new position, I was able to redo some of my previous steps and, of a sudden, I had my gold bar:

That was a real odyssey!
I had a sort of muscle memory of what I thought that I had done to release the gold and attempted to reset the puzzle. Everything went back inside and it looked perfect... or so I thought!

Of course, I usually do these puzzles several times before writing about them and on my second time through, I underwent the initial unlock process and then the second step using the tool. After this the gold bar was removable - something was not right! I looked inside the box and realised that the critical move that had taken me so long to find had not been undone when resetting. I duly went through that move a second time and it still saved too easily. What was I missing?

Continuing to stare deeply into the box, I noticed that the critical move that I had found wasn't a locking or unlocking move. In fact, I could not understand what it did. That is odd because I definitely remembered being absolutely held up before I found that move. I needed to understand what that move had enabled - time to look at one of the removed pieces from the puzzle.

Aha!

Oooh! That is very clever! After an extra day of fiddling with the puzzle in pieces I realised that this puzzlebox has at least 3 locking mechanisms (it might even have 4!). It is possible to open it without fully realising the extent of these mechanisms but only when working out the full reset do you realise just how much has been put into it. This is a tremendous puzzle made better by working to open and then reset without resorting to the solution videos. Take the time to explore and think© and you will be left with a huge grin on your face.

I might even go as far as to say that the vertigo puzzle is cleverer and more enjoyable than the original aMAZEing puzzlebox. You should definitely check it out. Those are the only puzzles on their site just now but I really hope that they continue to produce more - they both are absolutely fabulous.

A Puzzling Tribute to Christoph Lohe

Very sad news
After my last post (about Christoph Lohe's marvellous design, Neighburr) I received an email from both Laszlo Molnar and Goetz Schwandtner with the very sad news that Christoph had sadly passed away at the end of January this year. It would appear that his family had not had contact with him for a  few days and contacted the police and he was found in his flat. It has been judged to be natural causes. As many of us puzzlers are getting older this sort of thing should not come as a shock but he was only 65 years old. I guess that with what I do for a living, I should not be that surprised.

He was a significant scientist having  received a MSc in Experimental Physics from the Technology University Aachen in 1989 and a PhD in 1993. He worked as a Product manager Ferrofluidics, Nuertingen, Germany, 1996-2000. Project manager Aixtron AG, Aachen, since 2001. As a scientist of note he had been listed as a noteworthy physicist by Marquis Who's Who.

I considered Christoph a friend. We had never met and I was not constantly in touch with him but we exchanged emails every few months to discuss puzzles and his wonderful designs. You can still buy some of them from PuzzleMaster here or print them yourself from Thingiverse here.

His amazing skill as a designer is shown by the fact that I have reviewed 20 of his wonderful designs here on my little section of t'internet. I thought that it would be a nice think to look back at a few of my absolute favourite of his designs. 

Collaboration with the TICMaster, Andrew Crowell
Cyburr and Chamburr from Pelikan
Climburr from Matt Nedeljko               
When the first 2 came out from Pelikan, I wondered whether these two masters of puzzle design had created a completely new type of puzzle and raved about them. They made my top 10(ish) in 2021. The Climburr was felt to be too difficult to produce in wood by Jakub and it was only when Matt Nedeljkogot the courage to attempt them did we get to attempt the final one in the series. Spoiler alert - it was fabulous and made the top ten in the next year.

Locks, Locks, Locks!
Burrlock E
Key Trap
Christoph had a bit of a thing about locks and keys but not in the classical sense. He designed burrs in that shape. The fun thing is that rather than make simple 6 piece burrs where the pieces interact in the 3 axes, Christoph made the burrs with a frame to restrict movement and a key and shackle (and pieces) to lock up in at least 2 of the axes. The one amazing thing about all of Christoph's designs is that they are not terribly high level but are always challenging and fun without being too arduous. I absolutely adored these. The fact that even the late Eric Fuller thought well enough of these to make one of them, does show how good they were.

Framed Burrs
I adore a burr that has just the standard 6 pieces but is constrained in its movement and interaction by the presence of a frame. It makes them so much more interesting.

Neighburr by Brian Menold
Bouquet
Castle
Timburr
Again, we have puzzles that are so good that both Jakub and Brian Menold decided they were worth putting the effort into manufacturing in reasonable numbers. They all had something special and were all great fun without being too difficult.

Unconventional packing puzzles
Whenever I think of this particular type of challenge the names that always spring to mind are the incredible Alexander Magyarics and Osanori Yamamoto. But they were not alone, Christoph also had a fascination with these and designed some amazing puzzles:

Liliput
Trenta
Box with 2 balls
Kamelle Box
This is only a few of his great contributions to the puzzling world as well as to my collection but they include my favourites.

Do you have any favourites that you think should be given special mention? If so then please leave a comment below.

Rest in peace Christoph - I was proud to call you a friend.
