Puzzle Meta-Storage - Clip Box

Clip Box by Yavuz Demirhan
I store most of my puzzles in clip boxes and I find it amusing that I will now have to store a Clip Box in a clip box.  In one fell swoop, my storage solution just got elevated to a meta-storage solution.

Clip Box by Yavuz Demirhan was Klaus Kestel’s exchange puzzle at the International Puzzle Party 41 (IPP41).  The Wenge box is nicely made with corner lap joints and a Mahogany floating bottom.  Each of the 2 Padauk (if it’s not Padauk, let me know) clips are cut as a single piece of wood and then beveled.    It’s possible that the 4 pieces are made from White Oak.  But of course, it’s just as possible that they’re not.  Lastly, the steel ball bearing may be made from …. Steel?


Step 1: Figure Out What The Objective Is

The puzzle doesn’t come with written instructions and after hearing 72 puzzle descriptions during the exchange, I hope that I can be forgiven for not remembering the directions for each.  The puzzle consists of 4 wooden pieces and a ball bearing that need to be packed into a box with a clipped opening.   It comes with one of the pieces sticking out of the top of the box.

My assumption was that this is an apparent cube puzzle (good guess considering all the voxels are filled) and that the ball bearing would be on the bottom layer (or at least under one of the clips).  With all the voxels filled, you know that the last piece will just drop in with 1 move.

Step 2: Solve The Puzzle

The first assembly that I tried had a piece in an impossible orientation within the box, so I decided to analyze the various orientations for that piece.  For this particular piece, I found a nice rotation that I thought would be integral to the solve, but of course, I was wrong.  After looking at some possible assemblies, it turned out that the solution was straight-forward and didn’t require any fancy moves.

Clip Box Alternate Objective
Step 3: Doubt The Solution And Perhaps the Objective And Make Up Some New Objectives

I felt like I was missing a constraint with this puzzle.  The solution that I found required only 5 of the 7 open voxels at the top of the box.  So I thought maybe I should try to make an apparent cube with any 3 of the four pieces with the ball bearing trapped inside.  Although all 4 combinations are possible, none of them were very challenging.

Step 4: Continue Doubting And Keep Strategizing New Objectives

I then used that nice rotation I found and built an apparently overflowing cube with pieces sticking 1 voxel higher than the top of the box for the 7 voxels not covered by the clips.  However, there were other solutions to this format that didn’t require that fancy rotation.

Step 5: Seek Advice And Completely Solve The Puzzle

I reached the point where I thought it best to get some advice and placed a post on the Mechanical Puzzle Discord (MPD).  In hindsight, I should have guessed the response that I received.  My assumption about the objective was correct but there are 2 solutions!

Dedicating a little more time, I discovered the second solution, which turned out to be more interesting than the original solution that I found.   Altogether, I got a lot of puzzling out of this little guy.

Not Curly Burl – Curly Burr N8

Curly Burr N8 by Frans de Vreugd
I like all sorts of puzzles, but I still consider myself to be a burr guy.  As such, I always look forward to Frans de Vreugd’s International Puzzle Party (IPP) exchange puzzle every year.  This year’s puzzle, Curly Burr N8, was designed by Frans himself and made by Pelikan using Maple and Merbau.  Should have been Curly Burl Maple – just sayin.  However, one of my pieces is curly on the end.

The information that comes with the puzzle indicates that it has a unique level 8 solution.  This means that it takes 8 moves to remove the first piece from a fully assembled puzzle.  Unfortunately (or fortunately), it comes unassembled and there are quite a few required moves before the last piece gets put in.  And they forgot to mark the piece the goes in last.  Of course, being the expert burr puzzler that I am, I started with that piece as the first piece.

I always enjoy solving 6 piece burrs.  I start by taking the pieces and examining them.  Each piece is new and has its own specific role to play in the solution dance.  This ensemble has a pair of twins, which helps to reduce the complexity a bit.  While experimenting with the pieces, you develop a feel for how the notches and nobs are used and given the nature of these particular pieces, how the pieces have to move to start a disassembly process.

Curly Burr N8 Pieces
I worked on one assembly for a while, but was not able to get to the finish line with it.  As difficult as it is to break away from a potentially promising assembly, I reversed some of the pieces to successfully solve the puzzle.  Along the way, I discovered that the piece that I started out with needed to be the last piece, and I found it a bit of a dexterity problem to hold all the pieces in place as I juggled the remaining pieces to swap it out and then reintroduced it later.  Once it was added, it was just a matter of manipulating the pieces to close it up.

This puzzle does have a red herring.  I was continually puzzled by an aspect of one of the pieces.  After solving the puzzle, I was left wondering if it had been used without me noticing it.  So, I carefully disassembled it while keeping a close eye on this piece and I was left with the impression that it had more capability than was being used.  Next, I looked at all the pieces.  It was then that I realized that this feature was not there for the solution but for the manufacturing.  I approve - well done!

As of this writing, there are still copies available for purchase on Pelikan’s website.  If you are a burr person like myself, I highly recommend getting it.

SPLIT ASUNDER, RE – CONNECTING CUB3S

This puzzle is cubular dude!  Albeit a bit broken.  

You might be able to determine the number of cubes from the name of the puzzle.  Each of the cubes is split in twain and your mission is to reform the cubes asunder.  There are also some rectangular tubular pieces to be cached in rectangular receptacles of the cubic halves, each half having half of a whole hole.  Magnets were also added to make this a very attractive puzzle.  

This puzzle was designed by Tanner Rayes, that famous celebrity from the YouTube show What Did I Get Myself Into? and used as his exchange puzzle for IPP41.  New episodes of W.D.I.G.M.I.? have been temporarily put on hold for the development cycle of this puzzle, but I’d expect them to restart again after Tanner and his co-hostess Geneva open their new studio.

When I first saw the pieces for CONNECTING CUB3S, I was immediately reminded of the Impossible Triangle of Three Cubes puzzle by Andrey Ustjuzhanin and thought it would have a similar solution.  It didn’t, so forget that I mentioned it.

Tanner 3D printed the CONNECTING CUB3S himself and they came in a sturdy plastic box for storage.  The cubular pieces were black and the tubular pieces were Red, White, and Blue, keeping in theme with IPP41 which was held in the US.
 
Although constructing the attractive tri-cubular-cached-tubular shape was not difficult, the though process was enjoyable.  To be honest, I think that I found it easy because I had a good guess what the target shape would be.  For less experienced puzzles, it may provide more of a challenge.  My biggest problem was 2 pieces not wanting to go nicely together.  This was due to a rogue magnet that crashed the party and was hanging out with a buddy in one of the hole halves.  Once it was removed, the pieces slide nicely together.

I ended up laughing during the second challenge, which is to place the pieces back in the box.  I thought I would be able to just dump the pieces back in, but it required placing them inside with a little thought.  Not difficult, but you can’t just drop them in either.

Altogether, a nice package from W.D.I.G.M.I.? H.Q.

Don’t Sleep On This One – InsomniAC1

InsomiAC1
Wow!  Just Wow!  What a ball buster!

Given the way the title is presented and the fact that this puzzle is not a lock, you figure there is a good chance that this puzzle was designed by Andrew Crowell.  And you would be right.  And being designed by Andrew Crowell, you know it’s going to be great.

InsomniAC1 was Yacine Boucef’s exchange puzzle for IPP41.  It is an apparent cube (or squat cube in this case) packing puzzle where all the openings need to be filled.  The woods are not provided on the packaging but I would guess that the pieces are made with Wenge, Padauk, and Mahogany with a Maple box.

I found the assembly early on but that was the easy part.  I’ve learned with these types of puzzles that if it looks like a good assembly and has a couple of good moves, it’s probably the one you are looking for.  All you need to do now is discover the sneaky moves that are required to complete the insertion sequence.

This one was tough.  Not only was the solution a challenge to find but the required rotations, were not simple to perform.  This was exacerbated by the diminutive size of the puzzle.  It’s not easy to manipulate the pieces through the opening and of course the pieces conspire against you by getting in each other’s way.  And no, this is not one of those puzzles where when it’s solved, the first piece drops right out.  Far from it.

Usually, I store these puzzles in the solved state so they take less room but for this one, I’m a little concerned that I may forget how to get the pieces out.  I may store this one in an alternate configuration.

I recommend getting one if it becomes available.   And if you have the opportunity to acquire a larger one – go for it!

Gratitude For Those Who Work Up Through The – Eleventh Hour

Eleventh Hour
Having just returned from this year’s International Puzzle Party (IPP41), I’m extremely grateful to have had the opportunity to reconnect with friends that I haven’t seen since before the pandemic.  After a long hiatus, being immersed back in the community has helped rekindle that puzzling spirit and revitalize the pursuit of designing and solving new puzzles.

Note that I didn’t start to talk about puzzles.  The puzzles are a means – the friendships are the ends.  It’s about meeting and spending time with like-minded people that share a common interest.  Of course, this is not to say that I didn’t come back home with a suitcase full of new puzzles.

To successfully pull off such a large undertaking as IPP requires a dedicated host, committee members, and a cadre of volunteers.  All these people work extremely hard to establish a welcoming environment for everyone to enjoy.  Many of these people have invested years of effort to provide a smoothly run event lasting only a few days.  They work so hard and make it look so effortless.

On the last day, it is customary to honor these people that created, managed, and upheld the support structure of IPP.  And what better way than to award each with a puzzle.  Apropos for the volunteers who worked so hard to the very end, this year’s puzzle was: Eleventh Hour.

Eleventh Hour partially disassembled
Eleventh Hour was designed by Goh Pit Khiam and was materialized in Maple by Tom Lensch.  The puzzle is a classic 4x4x4 cube consisting of 4 pieces and as you would expect from a puzzle made by Tom, the fit is excellent.  My copy came unsolved, and I found the solve to be straight-forward without any twists (i.e. there are no rotations; this is not a Turning Interlocking Cube (TIC)).  Having designed a volunteer gift in the past, I know that one of the design goals is to avoid providing a puzzle with a difficult solution.  I won’t tell you how many moves it takes to remove the first piece when it’s assembled but if every move takes an hour, there is a clue on how long it will take.

I’m certain that the volunteers will cherish this token of the hard work that they dedicated to make this IPP a success and it will bring back fond memories of the good times that they had.

Ménage à Trois – Two Guys & a Gal (Free Me 9)


With a name like Two Guys & a Gal, you know that the situation will be complicated and you’re in for a protracted fight.  As the name suggests, this puzzle houses a lady flanked by 2 Johns.  More specifically, Lady Liberty and 2 John F. Kennedy’s.  I’m sure every puzzler’s favorite part will be Lady Liberty’s backside featuring a nice selection of gears symbolizing American Innovation.

Two Guys & a Gal was designed and made by Joe Turner.  This is the 9th puzzle in Joe’s Free Me series.  It is a sequential discovery (SD) puzzle concealing several imaginative and tricky mechanisms that need to be overcome to release the 3 trapped coins.  The puzzle was made with Cherry, Maple, Coins, and assorted hidden attractive and unattractive metal bits.  The attention to details like ensuring that the grain flows across piece boundaries makes the puzzle a work of art.

The puzzle houses an amazing 3-part journey to release the coins from their resting place.  This SD adventure uses several tools discovered along the way allowing you to continue the journey along the solution path until you finally arrive at the destination.  Of course in the beginning, it’s just you and the puzzle.  Just keep repeating to yourself: I’m just a tool.

This puzzle was so good, I couldn’t put it down.  Once I started, I didn’t stop until I had freed each of the coins and then reassembled it.  When I initially reset it, it seamed right but didn’t quite seem right.  One of the coins appeared too loose and I thought that maybe I had worn out one of the mechanisms.  After analyzing the associated mechanisms closer, I realized that I failed to properly reset it.  Once properly reset, it was back to the state that it arrived in.  So if it looks like you’re done but it’s loose, you’re not done.

From start to finish, the tools and mechanisms never ceased to amaze and delight me.  I can’t wait to get my hands on Free Me 10 next year! {insert seed of rumor here - done}

PPing in the Big Apple - NYPP 2024


After a long hiatus, I’ve finally gotten back to PPing.  And what better way to start than with the 2024 New York Puzzle Party (NYPP).  There’s nothing like a good PP to brighten your day.  The best part is reconnecting with all the other puzzlers you haven’t seen in ages.

The NYPP used to be held in February to align with the World’s Toy Fair, but has now been moved to the end of April to celebrate the end of tax season.  No more sloshing through wet snowy drifts in the middle of the Big Apple, but no one is complaining.

The best part of NYPP is seeing all the puzzle displays and getting the opportunity to play with new puzzles.  There is always a nice variety of puzzles and puzzly things to fiddle with.

Geared Mechanisms

NYPP 2024 was held on 20 April.  My goal this year was to ensure that nobody bought one of the Completely Broken Soma copies that I brought, and I’m proud to say that I successfully accomplished my mission even though the best part of NYPP is the opportunity to buy/sell/trade puzzles.  That reminds me that I need to post another Completely Broken Soma warning update.

Of course the best part of NYPP is the schedule of presentations.  This year’s speakers covered a variety of topics:

Josh Rosenfeld
Giving Puzzly Gifts – Josh Rosenfeld, ODES UNBOXED:
Josh shared the story of his journey in developing personalized puzzles tailored to the recipient.  A journey starting with a birthday puzzle adventure through hundreds of gifts later as a business.  Josh’s presentation centered on his approach to developing these gifts and highlighted 5 stages:

  1. Identifying what you want the gift to convey.
  2. Crafting the giving of the gift.
  3. Building a world for the recipient to inhabit.
  4. Shaping the puzzles around what a person loves.
  5. Revealing meaningful rewards.


Henry Segerman
Geared Mechanisms – Henry Segerman: Henry started with an update on his work with Holonomy and its application to puzzles.  He started with the pursuit of complexiturizing the flat 15 puzzle until it morphed into “something that you don’t want to play with”.  Several holonomy examples were shown, demonstrating that a moving piece following a complete circuit will have a different orientation at the end of the circuit from when it started.  Examples included the Dodecahedral Holonomy Maze and the Continental Drift Puzzle.  Henry did confess that the next generation 3D rotational holonomy puzzles are not fun to play with.  Sounds exactly how I market my puzzle designs.  After the holonomy update, the main portion of the talk was on geared mechanisms.  Best of all, Henry had table full of examples on display that could be played with.

Michael Cahill
Games Magazine Archive – Michael Cahill:
Mike picked up where he left off at the last NYPP that I attended (back in 2020) with some more game show trivia.  This year, Mike gave an overview of:

  1. The Devil’s Plan – Korean game show featuring a reality competition based on strategy games.
  2. The Floor – Time based trivia show.
  3. Generation Gap – Cute game with a psychologically damaging endgame.  Mike pointed out that this game scarred family relationships for life.

The main portion of the discussion focused on contests that went awry and one in particular that was put out by Games Magazine.   Mike researched this by going through old issues of Games Magazine on archive.org after seeing a news reference to a large contest payout due to an error in the execution of the contest.

Glenn Iba
Waffle Puzzle – Glenn Iba: I believe that the title of this discussion was Cuyler Cannon but my faulty memory failed to produce a reason why.  The discussion centered on the process of creating a program that could solve the daily Waffle Puzzle.  Glenn provided a step by step approach on how such a program is constructed.

Haym Hirsh
The Soma Renaissance – Haym Hirsh:
Haym provided an overview of the multitudinousation of the Soma cube developed by Piet Hein in the 30’s that has spawned and continues to spawn Soma variants with no end in sight.  Haym fessed up to contributing to this pandemic but cast blame on others as well including Theo Geerinck, Oskar van Deventer, Lucie Pauwels, Frans de Vreugd, Brian Young, Rick Eason, Martin Watson, Volker Latussek, Andreas Röver, and even that Soma mangler, Ken Irvine.  As fascinating as the Soma history review was, it was overshadowed by Haym’s mastery of hand puppetry.

Dick Esterle
Still Amazing, The Windy Windy Twisty Route – Dick Esterle:
  Dick presented some material that he had shown at G4G.  The presentation provided a Glimpse of the geometry that Dick uses to create puzzles as well as the Amazing Geometry Machine


I must confess that at one point I was that annoying audience member making those clack, clack, clackity, clack sounds during one of the presentations as I tried, mostly unsuccessfully, to cram 3 simple (but oh so complex) pieces into a box.  One of those, looks simple but not possible, puzzles.  The fact that the 3 pieces, Curvy, Bendy, and Wavy were not too steady on their feet caused them to tumble down in a rather noisy fashion.  Undeterred by venomous stares, I continued to clack away.  At least I assumed that there were venomous stares since I sat in the back and could only see the back of everyone’s heads.  However, I did manage to get most everything back in the box.
