Hanayama Cast Shift

Update 24 October 2017 - Dear Reader, please check out my new puzzle blog and e-store at http://mechanical-puzzles.com

One of Hanayama's latest Cast Series puzzles, the Shift was released in February 2017 with their updated and contemporary packaging bearing the name "HUZZLE", a combo of the words Hanayama and Puzzle. I was very fortunate and had the great pleasure of receiving the Shift (and Box Dice puzzle) over a nice Japanese dinner from the management folks of Hanayama, namely Kunihiro Kobayashi and Takeshi Onishi, the President and Sales Manager respectively, when both gentlemen were in Singapore for a business trip early this week. 



Measuring 4cm all round, the Shift at first glance looks somewhat like a 4-piece interlocking board burr made of metal; and there are a couple of other such similar looking wooden designs such as the Lattice and Four Frames designed by Andrey Ustjuzhanin. The Shift is cut from sheet metal (thanks to fellow puzzler/collector Michel van Ipenburg who pointed this out) and chrome plated to a glossy shiny surface. The 4 pieces consist of two congruent pairs with slots and corner triangles cut into them. If it's any help, let me say the triangles are cosmetic only and doesn't affect the solve. For better grip perhaps. 

The Shift was designed by Russian designer Kirill Grebnev who, together with Dmitry Pevnitskiy, was also behind the Cast Harmony puzzle. Apart from physical appearance, there is no other similarity between the Shift and the type of wooden board burrs named above. Certainly not the solving! Quality wise it's up to the usual Hanayama standards which is very good. Takeshi-san, the Sales Manager was telling me that Hanayama has a stringent quality control programme particularly for their puzzles that are manufactured outside of Japan. I don't own many Cast Puzzles but for those that I do, rarely have I encountered any real quality issues. The tolerances for the Shift is just nice and the pieces slide and move smoothly.

The Shift is rated 3 stars for difficulty, meaning it is of average difficulty. Give the Shift to an experienced puzzler and the difficulty quotient would probably be, well, average. But to a pure novice, it could mean "damn difficult" or impossible. IMHO, I think the rating here is about right. It's not too difficult, but certainly provides a fair measure of challenge. It took me a good 10-15 minutes before I figured out how the pieces interacted to unravel them. Oh, Burr Tools won't work here for sure, cos you can't solve it the normal burr way.

Once the prices came apart, to put them back together again was just the reverse procedure. Just make sure the right pieces are slotted against each other or you'll find yourself getting a bit stuck. With practice, the puzzle can be easily repeatedly solved. Like most of the Cast Series puzzles rated 3-star for their difficulty, the Shift is good for both the casual and experienced puzzler alike. For me personally, I like the Shift because I can see all the pieces and nothing is hidden from view, and the solution is pretty elegant. A fun solve no less.

And for the very reasonable price of the Cast Series puzzles, typically around US$11.50 to US$12 each, you would be hard pressed to get better value elsewhere, both in terms of overall quality and puzzle experience.

Seven & A Panic Attack

The last couple of evenings I had the opportunity to play with two very different puzzles. Both while challenging, were not unduly difficult. Fun (not frustration) was the order of the day.

Seven

The last time I came across something entitled "Seven" was the thriller movie with Morgan Freeman and Brat Pitt. If you have not watched it, do so...you won't regret it.



Seven (the puzzle) is no less thrilling. It is a 2D packing puzzle by Minoru Abe, who is very well known for his cute and whimsical, colourful and some extremely difficult sliding block puzzles. Minoru Abe puzzles are retailed by Torito in Japan. Unfortunately they do not ship internationally. Your best bet is to buy from CU-Japan unless you happen to have a friend who lives in Japan who can get it for you. My copy came to me courtesy of puzzle blogger Roxanne Wong, who got me a copy while in Tokyo last year during IPP33. 

As far as I know, Minoru Abe designed only two packing puzzles, the "Seven" and the "9 Puzzle" (the latter which I will review another day). If anyone is aware to the contrary, please drop me a note, thanks.

The Seven consists of 7 pieces (all Hexominos; ie 2D or 3D shapes made from 6 square units) and the accompanying tray. Object is to fit the red piece outside of the tray into the tray with the rest. None of the pieces are identical. The pieces and tray appear to be made of pine with the pieces painted over to give them that colourful look. Very well made with both the tray and pieces really thick and chunky and nicely packaged in a blue cardboard box. One corner of the tray has been deliberately cut away to leave space in the packaging for the red piece that needs to go in.

It took me about 5 to 10 minutes of fiddling with the pieces to solve. Only one solution I think. A rather pretty and fun packing puzzle that is not too difficult.

Panic Attack
I am not a fan of wire or string type puzzles. In fact I have only a few in my collection, one of which, the "Tricky Dick" which I had blogged about quite while back and the others are several handmade jungle puzzles.



Panic Attack was loaned to me by puzzle designer Goh Pit Khiam. I had mentioned to Goh that I found wire puzzles too difficult and frustrating and he told me to give Panic Attack a shot. And I am very glad I did. And I also did not for a moment panic while playing with it.

Panic Attack (as marketed by PuzzleMaster) was designed by Kirill Grebnev and was entered for the IPP26 Puzzle Design Competition under the name of "Love Secret", which subsequently was changed to "Clear Heart". Check out the interesting reasons for the change on Kirill's site.

The object is to get the yellow loop completely off the wire heart. At first glance Panic Attack seems like its impossible to solve; no way out for the loop. But this "impossibility" is more illusory than anything else! I am not sure if readers here would agree with me, but wire and string puzzles are probably the biggest group of puzzles which resemble "impossible objects" (things that appear to defy physical laws)....at first sight.

The first evening playing with Panic Attack, I couldn't figure it out and left it. However the next night, out of nowhere I extracted the loop within minutes of trying! With a bit of practice I even managed to repeat solving it in seconds!



It is not too difficult as a puzzle, but pretty tricky. A nice a-ha moment when you solve it. What I like about it is that the design is relatively simple looking. You know its probably hard, but It doesn't intimidate and put you off....unlike the wood and rope puzzles where the rope is so long, it entangles even before you start to seriously work on the solve. And certainly Panic Attack is also nowhere near the difficulty of a puzzle like Tricky Dick.. I am now even seriously considering other similar type wire puzzles to buy!
