The Silent E

The Silent E

Hi everyone! This blog post may well be a little less than my usual coherent standard. This is for 3 reasons: Firstly, I have been working my arse off (for you US citizens that would be ass!) and have spent all day at the hospital today and got home really quite late having worked for over 11 hours without any kind of break at all (My goodness, I needed the loo when I finished!) Secondly, one of my cats has just had a steroid injection and is now quite whizzy! He spent most of last night howling around the house keeping me awake with his zooming! At one point he ran across the pillows during the night and ran into my open mouth - yes I was on my back snoring my head off! I could swear that he had just been in the litter tray!!! Blech! But to really ensure that I am not coherent, the present Mrs S has served me an extremely strong Margarita when I got home and I am pissed as a fart as I write this. Luckily for you, some of the puzzling details have been jotted down in advance! So I do apologise!

Tonight I am going to review the Silent E puzzle from Puzzle Master's Wire puzzle collection. This is one of the few of their collection remaining that is a reasonable difficulty level and does not have string. It is a level 8 (Demanding) on their 5 - 10 scale. I initially thought that this rating was a little high but having watched others try it, I suspect it is correct. It arrived in the usual very nice clamshell packaging with the card insert saying just that the aim is to remove the brass ring from the puzzle. The actual description says:

"Are you going to spin or show some spine and solve this puzzle? Use the "E" to get it done. Easy for some; not for others. Where do you fit?"

his, as usual, is not in the least bit helpful! The picture says it all - remove the brass ring!! This is a pretty decent size of puzzle - 17.1 x 8 x 5.1 cm depending on which way you arrange the pieces. It is well anodised and very nicely made. All of these seem to have the same problem that the brass ring gets quite discoloured but that doesn't interfere with the puzzling. Gabriel enjoyed it, having reviewed it here. No solution is provided and if you need one it can be downloaded from here.

Ball in Cylinder II

Ball in Cylinder II

A few weeks ago I informed the world that Jerry had a new version of his Ball in Cylinder puzzle. Very imaginatively he named it the Ball in Cylinder II! I have known that it was coming for quite a few months; in fact I had been told that he had a new design in his head shortly after I communicated with him about having solved the first one.

This dummy thought
the stick was part of it!

To save on postage, Jerry gave a little bundle of these delightful little puzzles to Allard to bring back from the IPP in Japan and a few days after Allard returned, I received my copy and quickly told the world.

My initial pictures posted included the little stick which came with it. It was so beautifully finished that I could only imagine that it was to be part of the solution! It was made of bamboo and even had a nice clear rubber cap on the end. Allard suggested that it may have only been for transport purposes and this was confirmed by email from Jerry! Yes I'm a dope! But it just looked so perfectly made! The whole thing is just superbly made - these puzzles are designed by Jerry and he then takes the design to a local metalworker who hand fabricates them for him. The hand-made quality just shines through everywhere. To mark it out as BIC II there are 2 grooves around the top and bottom as opposed to the 1 on BIC I. The finish is stunning, really nicely polished aluminium with all edges smoothed so as to have a slight chamfer and nothing sharp to catch yourself on. This attention to detail is the mark of a fine craftsman and a fine designer. In fact I would say that the quality is as good as the puzzles I have collected over the years from Wil Strijbos. Unlike the puzzles from Wil, the BIC II is also available in copper for a slightly higher price. I have to say the copper looks stunning BUT really gets tarnished quickly with the handling required to solve it - You will need to make up your mind which you prefer and maybe choose to solve it whilst wearing gloves or polish it regulalry! Thanks to Shane for the photo of a copper version.

Stunning in copper!

Found a ball? It won't come out!

Like the last one, no instructions are provided but it is obvious that the aim is to remove the ball bearing from within the cylinder AND understand the process well enough to be able to do it repeatedly. I had mentioned last time that looking in the hole in the top there is a nice shiny and rather large ball bearing which slides back and forth in a track. It is far too large to come out the hole. Huh? If it won't come out of the hole then how are you supposed to remove it? Dope again! Holding the large ball still with the bamboo stick whilst inverting and swirling the puzzle reveals quite a bit of noise - more than I would have expected for just one bearing in a track. Now the rather dense penny drops! There is a second bearing inside (at least one - can there be more still?) so I had to assume that it was the aim to remove the other one that was hidden deeper inside the puzzle. Then, having been told it was not needed, I discarded the stick - I was on my own with no tools!

Parallel Dimensions

Parallel Dimensions

Another disentangle net puzzle from Puzzle Master! Yes I am totally addicted to all puzzles but even going back to the beginnings of this hugely expensive adventure, I loved the challenge (and the price) of the wire disentanglements - although that very first batch of Livewire puzzles really did cost a fortune up front and then I also had to pay the customs officers. In fact, to this day, Mrs S STILL doesn't know what that set cost me/us!

Last week's review was a relatively straightforward wire puzzle from Puzzle Master's own range and I am gradually working my way through as many as I can get my hands on! This time, I can finally write a review of a puzzle that I have been carrying around with me more or less everywhere for over a month! This one is the Parallel dimensions, rated as 10 (Mind Boggling) on their 5 to 10 point scale and like the review on the product page, I can whole heartedly agree with that rating. It arrives in Puzzle Master's usual plastic clamshell packaging and simply has the pictorial instructions to remove the yellow coloured metal ring. It is a good quality anodised wire and the string and wooden ball and cube are nicely painted. My only criticism is that the large brass ring seems to get tarnished quite quickly. It is 9.5 x 7.9 x 1.9 cm in size. No solution is provided with it but it can be downloaded from here - you may actually need it.

For those of you with wives (or even husbands) with laser stares this is not a good one for you!! I now have 2nd degree burns (i.e. partial thickness) over the whole of the right side of my body after playing with it and jangling away for over a month!!

Panic Attack

Panic Attack

Now I was going to review one of the latest Hanayama cast puzzles, the Cast Delta, but Gabriel got to it before me at the end of last week so I have put that one on hold for a while and thought I would delve back into the wire puzzles again. Today I am going to review the Panic Attack - one of Puzzle Master's own series of disentanglements.

I ordered this one because I wanted something a little easier than the level 10s that I had been trying previously. In fact I have been carrying one of them around with me (the Parallel Dimensions) for over a month now and have made no headway at all with it! I also wanted to try it because it bore a resemblance to the level 10 Eagle puzzle which I reviewed here and enjoyed immensely. I wanted to see how it differed and why it was considered easier. Panic Attack is a level 8 (Demanding) on the Puzzle Master 5 to 10 point scale. It measures 10.5 x 9.2 x 4.8 cm and is very high quality with the wire nicely anodised and the loop of orange twine nicely heat sealed. As with all of Puzzle Master's own range of wire disentanglement puzzles, it arrives in a clamshell package with pictorial instructions to remove the loop of string and the worded but not in the least bit helpful instructions:

"When having a panic attack, a person has to try to figure out the clues as to why this is happening.  You will also have to search for clues to solve the Panic Attack brain teaser"

Whilst you do need to think why it won't just pull off - this has nothing to do with panic! I actually prefer the original name (and description) for this puzzle given by it's designer, Kirill Grebnev, who also designed the gorgeous puzzle recently marketed by Hanayama, the Cast Harmony, which I reviewed here. It should not surprise anyone to find out that Kirill also was the original designer of the Eagle Puzzle which he called "Step in future". Kirill's original name for the Panic Attack was "Clear Heart", a much less macho name but definitely more evocative of the shape. It was designed in 2006 for submission to the IPP design competition and named because the aim was to remove something from the heart (sin? vice? string?) leaving one with a clear heart! Kirril's own rating is 3?s out of 5 which is the same as that given by the guys at Puzzle Master. At just $10 this is a nice easily affordable puzzle.

Gabriel reviewed it here and agreed completely with the rating. It took him several attempts before he solved it and was only able to solve it after returning afresh. He described it as a "perfect puzzle even if you are not crazy about wire puzzles". Beware his page has a photo and description of the solution. No solution is provided with the puzzle but it can be downloaded directly from Puzzle Master here.

200 posts - I have been VERY bad!

I really cannot believe it! This is my 200th post and, looking at my analytics data, I should achieve 200,000 page views in the next week or two! Is this a cue for a torrent of mushy nonsense from me? No! Yes! Alright - just a little bit. It hardly seems long ago that I passed the 100 post mark - this time I'm going to be:

"Wondering about wood,

being 'Fuller' it,

admiring the Pelikan,

being amazed at a burl

and finally, going CraaaazyBad with Traiphum"

I've not lost my marbles yet again - it will all make sense soon! Recently I have been buying new toys like there was no tomorrow so basically, to mark this occasion, I thought I would show off a few of the most beautiful and challenging puzzles that have arrived recently and describe my experiences with them. Many are still available for you to add to your collection. Hopefully this catharsis will make me feel better and help Mrs S forgive me!!!

Wood Wonders

Brian Menold is the head honcho at Wood Wonders (actually he's the only honcho) and I have been buying from him for 2 years now - his workmanship has developed during that period until it rivals some of the best in the business and like most (if not all) puzzle people he is a delight to communicate and do business with. During the penultimate sale, due to a quirk with the sales system on his site, I had all the puzzles in my basket snatched from me whilst I used my 2 factor authentication with PayPal - yes Nigel, I hope you feel guilty! As a result of this, he held the one puzzle I had managed to keep and when the next batch came out he contacted me to assure me that I would be able to get those I lost this time. Amongst a decent batch I obtained 3 particularly interesting puzzles from him:

Pyramidal Pile

4 Piece Pyramid

The first 2 are classic designs by Stewart Coffin and are beautifully made. It must be hard enough to make puzzles which are based on a cubic piece, but to make puzzles out of all sorts of other shapes just blows my mind! The pyramidal pile is, gulp, a sort of packing puzzle/construction puzzle. The lovely pyramid (made from Bocote with a Yellowheart tray) can be tipped out to reveal the pieces!

Cast G&G

Cast G&G - sorry it's really hard to photograph!

This may well be a little less lucid than my usual and may be a bit shorter due to fatigue - I spent all day yesterday on-call and writing several rotas too during the day. Unfortunately literally seconds after putting the light out at night, I got called in and had to work half the night. I slept late but an elderly man like me takes a very long time to recover!

Look a wood version!

Back in July I wrote about one of my Puzzle Master acquisitions, I mentioned my dwindling supply. Well I was very bad and placed an order for a whole bunch more so I would have some more reasonably priced puzzles to write about. This one, the Hanayama Cast G&G had been of particular interest to me since it had fascinated me when it won the Jury Grand Prize at the 2012 International Puzzle Party (IPP) in Washington DC for the designer Jin-Hoo Ahn. Firstly, the fact that it had won such a prestigious award really made it stand out and also the fact that it was a member of my beloved disentanglement group (from which you have seen me write so many reviews). Another reason for my fascination is that after discussing it with a friend from across the world, he made a copy for me in wood and sent it to me to play with long before the Hanayama version came available. Solving the wooden version confirmed to me what a great puzzle it is and that I would need to get the metal version too when it came out. He also made me a spare version which I gave to a great friend who organises the Midlands Puzzle Parties - I hope you have enjoyed it Nigel?

As puzzles go, and surprisingly for a Jury grand prize winner, it is not rated as terribly difficult - Hanayama rate it as a level 3 out of 6 and Puzzle Master as 7 (Challenging) in their scale of  5 to 10. Certainly, it is much less difficult than many of their wire and string disentanglements. As with all the Hanayama puzzles, it is beautifully packaged and the puzzle is firmly held onto supporting card to stop it jingling and getting scratched in transit. It is a perfectly portable size at 6  x 4.2  x 2.5 cm and feels nice and solid in the hand. It is a very reasonable $13 in price. Like all the puzzles made by Hanayama, it is beautifully plated in silver and gold metal and the gold piece also seems to be coated in a lacquer. I am not sure of the reason for the lacquer but it is not terribly robust and as you can see from my photos it very quickly chips somewhat spoiling the look (if not the puzzle experience). The instructions are to take it apart and put it back together again (obviously)! There is no solution supplied but it can be downloaded from Puzzle Master here.

A bonus for me - and so for you too!

Jerry's Ball in Cylinder II

I've been trying to keep my blog posting to just one a week so as not to overload you all. But today I received a nice little packet from Allard after his return from the IPP in Japan. It would appear that he had a great time and his exchange puzzle was well received. I know I am eagerly awaiting his and Rox's reviews of the exchange puzzles? This packet contained 2 wonderful goodies: Jerry's Ball in Cylinder II and Allard's own Magic suitcase puzzles.
A few days before the IPP was held, I received an email from Jerry Loo informing me that he had version 2 of his ball in cylinder finished and would appreciate my opinion of it. To save on postage across the world he proposed giving it to Allard who he would be meeting at the IPP so Allard could bring it back in his luggage. After a short humorous exchange about luggage allowance during which it would appear that either he had paid for many Kg of extra weight or, more likely, he had forgone any change of clothing and just taken empty suitcases! Can anyone report on how Allard smelled after several days of puzzling?

Eric Fuller! You are N times a genius!

Truly beautiful! From Eric Fuller

Idiot Alert!

I humbly stand corrected by my friend and fellow puzzle blogger, Tom Cutrofello! In my breathless delight at the genius craftsmanship of Eric I really did not adequately attribute the brilliant designers. Here is what Tom wrote:

"Go Pit and Bill are the design genii, Eric is the master craftsman! Amazing collaboration that would have been almost impossible before the IPP and the Internet. The puzzles are going to become even more elegant. We live on the golden age of mechanical puzzle world!"

Thanks for reminding me of my foolishness! Where would we be without the designers? I maintain that Eric is also a genius but I mustn't forget who enabled his genius. Apology over! Can I put my flagellation device (whip) away now?

Now those of you who are friends on Facebook will have seen that I have been making a very good attempt at bankrupting myself over the last few months! There just seems to have been a constant stream of absolutely fabulous puzzles coming out from all the puzzle designers and craftsmen. This is not just the wonderful wood workers but also the fantastic Chinese twisty puzzle makers who have made loads and loads of new twisties that are "absolutely essential" for my puzzling health!

Drool!

Double Drool!!!

It doesn't stop there either - there's also the fantastic twisty modders and Shapeways designers also keeping me sane .....! Yeah! really!

My original 3x5x7. New 5x7x9 (Traiphum) and 4x6x8 (Jeremy)

But despite all this, I have really been getting in to the N-ary group of puzzles and have been adding lots and lots of them to my collection. I established in my last blog post about them that there can never be too many of them in your collection and my aim would be to get a set as good as that of Dr Goetz Schwandtner. I am still a long way away from that but am certainly adding to my collection at an alarming rate - please don't anyone tell the present Mrs S how much they cost! No-one would even find my body!

Yin Yang Disentanglement

Helical burr

I've been a bit delayed recently due to work commitments and Mrs S going off up to Edinburgh to visit her parents meaning more chores for me to do! I've also not wanted to put out too much stuff when the deluge from the IPP is going to be out soon! First of all may I give my hearty congratulations to Derek Bosch for winning the Jury Grand prize in the design competition with his marvellous Helical burr which I gushed about here.

Jean Claude Constantin - Yin Yang

This week's post is about a disentanglement puzzle that I had thought was particularly attractive and involving string, I thought it would be a real challenge. I also would like to get more puzzles by the amazing and prolific Jean-Claude Constantin. This is the Yin Yang disentanglement puzzle (not to be confused with the puzzle of the same name made by Puzzlemaster that I reviewed here). It was originally rated as a level 8 on their difficulty scale of 5-10 and that was a major attraction for me - I was really hoping for a string puzzle that wouldn't hurt my head too much! Subsequent feedback from me has led to it being re-rated as a 5 (Easy) and is certainly good for beginners to this type of puzzle.

It is made from a nice quality anodised wire and a decent string with a bead on the end and arrived in just a small plastic bag with the name of the puzzle typed on a label. Certainly a decent quality and in size it is 6.2 cm in diameter and the bead makes it about 2cm thick. It is extremely cheap for such nice quality at only $5. The name is obviously related to the soothing Yin yang symbol it forms and it's not difficult enough to upset your inner peace! I haven't seen any other reviews of it anywhere and no one has commented on the PuzzleMaster page. Interestingly there is no downloadable solution on the solution site either but don't let this put you off! You really will not be needing it!

How many more N-ary puzzles do you need?

Just "N" more!

Today I want to tell you about some of my all time favourite puzzles - they combine maths, beautiful wood and puzzling. I want to start with a classic puzzle which has recently become available again and I think you should really consider picking up a copy. Following that I'll show you a few others in my collection.

Hexadecimal puzzle

Here you can see a brand new production of the Hexadecimal puzzle. The puzzle was originally made for one year only in 1986 by Binary Arts (now called Thinkfun). In that year 7500 were produced and only about 750 are estimated to still exist, most firmly in the hands of puzzle enthusiasts/collectors. They seldom come up for sale and command very silly prices. My good friend Michel has been searching for one for years and only recently managed to get hold of one. 

Presented beautifully!

He informed me that Dave Janelle of Creative Crafthouse has obtained permission to produce a limited run (max 190 copies) of this fantastic puzzle for us dedicated puzzlers. He has made them beautifully in Cherry and they are pretty much identical to the original. They are engraved, numbered and presented beautifully in a lined presentation box. The documentation includes that which came with the original puzzle. I managed to get number 6 which is the first to go to the public and can absolutely vouch for the quality and the puzzle enjoyment. They are available here for a very reasonable price.

It was designed and patented by William Keister (1907–1997) in 1986.  William was an engineer in the famous Bell Laboratories and one day he raided the Bell Labs’ stock room, gathering up pushbuttons, electronic relays, and light bulbs to build an electronic version of the Chinese Ring Puzzle.  After a few hours work, he realized he had wired it up wrong, but studying what he had done he also realized he had stumbled upon a whole series of binary code sequence puzzles, of which the famous Chinese Rings Puzzle was just one variation.  He went on to sketch out a whole series of logic puzzles and show how they could be solved mathematically with Boolean algebra, a precursor to today’s computer languages.

It consists of a sliding carriage and a stationary base.  The carriage is fitted with 8 rectangular switching bars which can pivot on their centres to angle in either of two directions.  The base, which holds the carriage during the puzzle’s operation, is fitted with an assembly containing 4 blocking keys. These keys can be present into any one of 16 positions. The object is to remove the carriage which contains the 8 switching bars.  By setting the 4 the blocking keys in various initial configurations, there are 16 puzzles to solve ranging from fairly easy (8 moves for position 1111) to extraordinarily difficult (170 moves for position 1110). It has been analysed (just like most mathematically based puzzles by Jaap here. Let me say that whilst I love Gray code puzzles and find most of them fairly easy, this is really taxing me! I have only done the first 6 so far and am very much enjoying it - you should really consider getting a copy because once this run is over, it is highly unlikely that they will ever be made again!

Here is Dave introducing this puzzle:

If you do own an original or buy one of Dave's excellent copies then it would be a great idea to enter your name onto the Hexadecimal hall of fame which is being kept for the world by Richard Whiting. See the list of owners here and toward the bottom of the page he has a link to email him to inform him of your acquisition. Richard also has an info page about these puzzles here.

Are there any other N-ary puzzles I can recommend whilst I am writing about the Hexadecimal? Indeed there are lots and many are available easily - read on:
