Hanayama puzzles, yet another update on the museum, and a job advertisement

Carrying on from my recent article in CFF, I would like to post a bit more about Hanayama.  I'm not an expert in the company, but do have a bit of insight and would like to provide it in today's blog posting.  The first thing I would like to do is to post a list of puzzles and their designers.  I've seen many people asking about these and thought it might be helpful information to have it posted here.  

Hanayama works with a number of designers the most prolific of which has to be Akio Yamamoto (Dot 2017, Dolce 2002, Baroq 2001, Amour 1992, Radix 2005, Helix 2009, Vortex 2008, Seabream 2010, Shark 2010, Claw 2010, Starfish 2019, Seahorse 2010, Reef 2010).  

Of course, the first puzzle designer was was Nob Yoshigahara (ABC 1983, Flag 1994, Horse 1984, Star 1983, S&S 1984, Ring 2000, Elk 1986, Devil 1994, Laby 1997, News 2003, Plate 2005, Cage 1997, Key 1983, W-U 1995).  Many of these were old designs which were later produced by Hanayama. 


Other designers include Oskar van Deventer (O’Gear 2002, L’oeuf 2004, Disc 2001, Twist 2013, Möbius 2015, Duet 2005, Equa 2008, Marble 2009, H&H 2010, Chain 2002, Cuby 2005, Nutcase 1987), 

Vesa Timonen (Loop 2007, Hook 2009, Square 2010, Ufo 2019, Donuts 2011, Keyhole 2015, Cylinder 2013, Dial 2016, Infinity 2016, Slider 2019, Valve 2021),

Marcel Gillen (Pawn 2015, Rook 2015, Knight 2015, Bishop 2015, King 2015, Queen 2015),

Kyoo Wong (Delta 2013, U&U 2014, Trinity 2018, Rotor 2019, Snow 2020), 

Jin-Hoo Ahn (G&G 2013, Padlock 2016, Hourglass 2018), 

Bram Cohen (Galaxy 2014, Marble 2009, Rattle 2010, Cake 2016), 

Kirill Grebnev (Harmony 2012, Shift 2017) , 

Dmitri Pevnitskiy (Harmony 2012), 

Edi Nagata (Coil 2011), 

Serhiy Grabarchuk (Coaster 2006), 

Eldon Vaughn (Enigma 2004), 

Harry Nelson (Spiral 2003), 

Scott Elliot (Love 2018, Diamond 2016), 

John Lynn (Bike 1994), 

James Dalgety (Medal 2009, Cricket 2002) 

Joseph Litle (Violin 2003), 

Andrei Ianov (Arrows 2018), 

Mineyuki Uyematsu (Quartet 2007, Hexagon 2015), 

Ken Walker (Spiral 2003), 

Jose Grant (Cast Ring 2 2004), 

Yoshi Kotani (Shift 2017), 

Yuta Akira (Box 2012).

Timothy Collins (Dice 2021)


There are also a number of puzzles that are no longer produced.  These include Oskar’s Key, Bike, Cast Key 1, Winnie the Pooh Horse, and the Ultraman marble. There were also a few puzzles produced in the early days that were much larger than they are now. Bike, W-U, Nutcase, News and Radix.  Of course, even though many of these are no longer being produced, they can still be purchased through different online retailers. If you notice any that I have missed, or mis-dated, please let me know.


The company experimented with plating the pieces in different colors.  Again we are fortunate  to have a number of these color variations in our collection.  


Over the years we have had the pleasure to visit not only the offices of Hanayama, but also a number of the factories.  We have seen the entire process from smelting to final packaging.  Photographs of our first trip can be found at My facebook album.


At first the company made molds of wood or clay.  Around 2010 they changed to puzzles made by CAD and 3D printing.  Many of the new puzzles have been made in CAD first, then produced using Injection Molding.  One puzzle, Cast Möbius was produced using spin casting and silicon molds.  A number of the puzzles are made of cut steel-Slider, Snow, and Hexagon are a few examples. The puzzles are mostly made of a cast zinc alloy. Once the puzzles are cast, they are removed from the sprue and hand sanded to remove any sharp edges.  After this, they are tumbled to remove any further imperfections before moving on to the metal plating process.  When we visited the Hanayama factory, we counted no less than 12 people who touched each puzzle during the manufacturing and 6 people in the boxing process.  When you think of it, they are incredibly inexpensive puzzles.  


Hanayama Cast puzzle was renamed Huzzle in 2015.  It is a combination of Japanese words that means “hugs and puzzle” (actually, these don’t look too Japanese to me).  Kyoo told me it is easier for Japanese to pronounce.  But then he teases me a lot so I don’t know if that is truthful.  George is reminding me of a time that Kyoo sent us to the wrong train station in China when we were going to go visit his factory.  No taxi driver would pick us up when we got off in the middle of nowhere. George had to run out in the street, stop the taxi by jumping on the hood of the car and then jumping in the cab before the driver could run away.  When we returned from the factory that night, the train station we should have gotten off at was 1 block away instead of 5 miles! What a jokester. 

 

Prototyped Puzzles
We have had the good fortune to be involved with Hanayama and their staff in one way or another for many years.  George was an early prototyper for the cast puzzles.  He worked on 14 puzzles in the early stages.  These include:  L’oeuf, H&H, Nutcase, Loop, Donut, Medallion, Duet, Square, Rattle, Twist, Hook, O’gear, Möbius, and Marble. This comes to around 19% of the puzzles produced.  I’ve been friends with the chief engineer in Hong Kong for many, many years. Because of this, we have been lucky enough to have many Hanayama prototypes in our collection.  In the photo below, only three were not made by George.  The Radix, Delta, and Keyhole were all gifts.  The Radix is made of compressed paper and is very solid. It was given to George when he held a puzzle exhibition in Sonoma, California.  Delta and Keyhole were given to me by Kyoo during visits to his office.  In the earlier days, George used a laser cutter to make the prototypes.  Later on of course, he went to 3D printing.  
Prototypes


All of these are on display and play terms for visitors to Puzzle palace.  Many of the puzzles prototyped by George are available for visitors to choose from the treasure chest.  The cast marble seems to be the favorite of most people.  


On to the weekly update of the museum build.  As of Friday, all of the cabinets have been placed and mounted.  The pool heater and pump are now both working beautifully. The outdoor recycling/garbage closet has been covered and is awaiting roofing.  The garage floor has cured and we are now just waiting on the puzzles to arrive.  We are more than ready for them.  

One container has been sitting down at Port Everglades since the 14th of May, the other is still on its way to Halifax.  In the mean time, I have shifted all materials from the main rooms so that we have area to place the moving-boxes when they come in.  I have developed a display system and each room in the museum will hold a specific type of puzzle. Being me, I have Roxified (color coded) the manifesto so that we know which room each puzzle should go into upon entering the house.  This will make the process of unboxing and displaying much quicker.  

I have also purchased a new camera and light box to photograph the puzzles as they are opened.  George has developed a cataloging system to ease the problem of display in the online database he is slowly working on.  Expect it to be completed sometime around July 2022 and be online and searchable by Christmas of the same year.  

When we contacted James about obtaining this, we were not thinking.  It was the most whimsical of purchases one has ever made.  Well, we've managed to accomplish nothing short of a miracle.  We managed to purchase a house, build it out, and have it all but ready for installation of the puzzles in less than four months time.  

Next up?  Hiring a couple of students to aid me in the photographing and cataloging of the puzzles.  Does anyone want a summer job?  Photographic knowledge required. Use of Macbook necessary.  Your own vehicle is a must. 6-8 hours a day from date of hire until puzzles are all on display or end of summer holiday. We prefer a student who is looking for experience. Pay?  Who needs money when you have puzzles? :) Oh yes, room and board included. I'm a very good cook and you can't beat the accommodations.

Flippe Ball and Exciting news!

 This week we had quite a few puzzles come in but since George is writing articles for CFF I'm not allowed to write about them here.  I chose to block him and today I give you the Flippe Ball puzzle by George Bell.  

I love it!  It's a fun little puzzle.  When it came in the mail, I knew it had to open through a spin.  I'm not giving away any secrets here as George Bell has recently written an article in CFF 114 about this puzzle.  I have to say, I was disappointed when I first tried to open it because nothing happened.  I sadly walked into the bedroom and gave it to my lover. He had the advantage of having read the article before the puzzle came in, he walked back into the kitchen, grabbed a plate and opened the puzzle!   I played around with it a bit.  Looked at it and realized what the trick was.  
I managed to finally open it after about 20 tries.  It's a fun little puzzle and I can see non-puzzlers enjoying it.  We are having a few visitors to Puzzle Palace next week, I think I'll take it out and see how it goes over.  This little gem along with other designs made by Mr. Bell can be purchased here

Flippe Ball


Speaking of CFF, this month according to Rik is unique.  They have more than enough material for the magazine.  Another first is that this is probably the first time they have had a husband and wife each write an article.  I gave a look at the Hanayama collection we have, and George introduces his die-cutting machine.  I have a feeling this will not be the last time we both have an article in the magazine.  I'm pretty sure we have both sent off a few more for publication.

On to the weekly update on the Puzzle Palace Museum.  We got some bad news this week.  The guys who are doing the epoxy floor came down with COVID-19 and will be out for another week.  This means the floor base coat will not be done when the decals arrive.  One has been completed and is sitting in George's office, the other is at the printer here in Boca.  The men putting all of the shelving up are working down in Miami finishing up a job and have put us on hold so not much going on there.  My daughter and a few friends from college spent a weekend here and it made me aware of what still needs to be purchased to make the museum habitable so I have spent a great deal of time shopping for the small essentials.  

I also realized we don't have any furniture in the Museum so I spent a few days hunting down coffee tables and large tables for the house.  It's not an easy task to find items we both like that keeps with the theme.  Then I stumbled across the Lost Day Burr Table.  This would be perfect! I wrote Sue right away hoping beyond hope that there would be an extra one sitting in the dark corners of Brian's workshop but there wasn't.  If anyone has one they want to sell, please let me know.  I'm looking to purchase.  We are also looking for a design for a larger dining room table.  It has to be a puzzle of course, and it has to be big. I need a rectangular one that will hold at least 6 people. It will probably not ever be used for that purpose, but rather it will be used to play with the puzzles that are in the museum.  

Our Castro Convertibles arrived 2 weeks ago and the chaps who were paid to install them dumped them in the great room and told us they would be back in a few days with more workers because they were too heavy for them to get up the stairs.  After a lot of unanswered calls by the delivery company, I called the manufacturer to complain.  15 minutes later our $400 was returned to us and we had to look for movers locally.  Well, not us. George decided we would take all the mattresses and cushions off and move it ourselves.  It almost killed us, but by golly, three hours we got them installed.  We slept well that night!

Halfway house looking over the golf course

Over at Puzzle Palace, the tree removal men came on Monday to grind down the roots that they didn't do the first time around.  The man said it was too much work for him and he'd be back with more guys after he had his lunch.  He never came back.  I called the landscaper and exploded.  We got the roots ground out on Tuesday and I had to miss golf again, but no landscapers or irrigation pipe fixers came this past week.  I have a very muddy front yard waiting to be beautified.

With everything going wrong this week, I was just ready to give up.  And then we got the best email ever.  Out puzzles were being loaded on the ship!  They leave the UK on Tuesday the 27th and should arrive in Port Miami on the 16th of May!  Now we know we won't get them for another 2 weeks after that, but at least they will be on the right side of the globe for us.  This dream is getting closer to completion.  Now to go make some phone calls to get those workmen back in the museum.

Heptagonal Star


This article was published in CFF #113.  We've attached it here with the Burr Tools files accessible to anyone.  Please enjoy the read.  


Solving Heptagonal Star Using BurrTools

by George Miller, Aug. 2020


Heptagonal Star was exchanged at IPP-18 in Tokyo by Yoshiyuki Kotani.  I was able to purchase a copy recently and it arrived as 7 flat pieces.  I wanted to display it as part of my IPP exchange puzzles collection, but did not know the exchange year, the designer or even the shape it was supposed to take.  By looking through the IPP-18 book I discovered the designer and the date of the exchange.  Sadly, Kotani san’s page neglected a solution or even a picture of the puzzle.  I was able to deduce the final structure of the assembled puzzle by its name, Heptagonal Star.

I quickly managed to piece together 6 of the 7 pieces, alas, the 7th piece stubbornly remained allows for man-insertable.  I decided to move on to the other puzzles that had come in the mail, but, decided to “cheat” by programming the solution using BurrTools.  After all, this is an interlocking combinatorial puzzle.


BurrTools allows for many different grids, but certainly not one with seven fold rotational symmetry.  I tried to simplify the programming effort by imagining this puzzle as a ring that has been cut vertically and spread out flat.  Each piece could be rendered rectangular by cutting the top and bottom of each hexagon.  Each piece had blockage at the top and/or the bottom in four places.  I chose a 5x3 rectangle to represent each piece. The first two blockages of each piece are represented by voxels in the first two columns.  The last two blockages are represented by voxels in columns 4 and 5.  The middle column is left empty as part of the weaving.


The resulting shape will be a flat 14x3 rectangle assuming I could connect the end of the rectangle with the beginning.  But, Burrtools has no such notion so I had to “fake” it by adding 3 variable voxels on both ends of the rectangle as such:






I know this will produce too many “solutions”, but I can go through the results by hand and pick out the real ones.  BurrTools gave 13 “solutions”.  I picked this one as the best one to try:



As you can envision,  the rectangle can be bent in a ring with the blue end fitting neatly under the yellow end.  Both the blue piece and the yellow piece have their blockages on just one side and thus could be dropped in as the last piece.  I started with the blue end and moved towards the yellow end by putting the blue into the red piece, the two green pieces together before putting the pair on top of the red and blue pair next the cyan and then the pink before dropping in the final yellow piece.


Realize that BurrTools is an advanced programming language which is “coded” in BurrGui, a graphical interface.  BurrTools solves the problem.  BurrGui describes the problem. The trick to coding this program lies in transforming the physical puzzle into the BurrGui language.  The language allows for disjoint pieces and variable voxels which used wisely can transform most any combinatorial problem into a BurrGui program which can be solved the companion BurrTools engine.


Below is the .xmpuzzle file.  This is a text file.  BurrTools can read both the text version or the binary version.  To get a text version, I opened the .xmpuzzle file in the BBedit application.  After loading it into BurrTools, go to the START tab and press the START button.  You should see 13 solutions.  Move to the 10th to see the above mentioned solution.
