One Tɍough – Ditch

Ditch was designed by Alexander Magyarics and entered in the Nob Yoshigahara puzzle design competition at the 41st International Puzzle Party (IPP).  Although it did not win a prize, it looked like an interesting concept worthy of spending time on.  And spend time on it I did!

Ditch consists of 12 bi-color pentomino pieces where each piece is comprised of a tetromino of one color and a monomino of a different color.  The goal is to make a 4x4 square outline with the 12 monominoes.  The problem is that all those tetromino bits get in the way of accomplishing this.

The first Aha comes early on to get you started followed by a long period of learning how the pieces can interact with each other.  Some off these relationships will help form the solution while others will lead you astray.  There were some relationships that I was unwilling to ditch that kept me from finding the solution for quite a while.  I found myself reluctant to divorce myself from these poisonous relationships and I found myself in rut with Ditch.

I eventually gained the willpower to break off some of those relationships, giving me the freedom to engage in some new, healthier relationships.  With something old and something new, I successfully managed to extract the solution from the Ditch.

There were many times where I had one piece leftover that would not fit in the available space. The natural reaction is to start moving pieces around to see if you can change the space to something more receptive.  I can certainly attest to that.  However, if you end up with the same troublesome pieces multiple times, it's worth taking some time to find them a good match and treat them as a couple.

Much nicer versions of Ditch in a selection of exotic woods are available at Wood Wonders if you would like to acquire your own copy.

Lacking QC – Messing a-round

Messing a-round is a 2D packing puzzle was designed by Alexander Magyarics and made by alienpuzzles.  It was 3D printed and used by Alexander as his exchange puzzle at the 41st International Puzzle Party (IPP).  The tray is white and each of the 8 pentominoes is made with a different color giving it a vibrant look.

The puzzle consists of 8 pieces that need to be packed in the tray although not all at the same time since the tray can only accommodate 7 of them.  The pieces are rounded and fit together nicely with each other.  However, 2 pieces are missing a couple of rounds and the pointy corners don’t fit nicely in the inside corners of other pieces.  Really, what has become of quality control these days?  At least these unrounded corners were discovered before distribution and the solution statistics were duly updated.  With these unrounded corners, the number of solutions for packing all the pieces except the T piece dropped from 128 to 1.  Similarly, the number of solutions without the Z dropped from 95 to 2 and the solutions without the L dropped from 19 solutions to 1.  It’s almost as if the corners weren’t rounded on purpose.

Although those unrounded corners are initially awkward, you quickly get a feel for what pieces won’t go together well.  Given that roughly 99% of the potential configuration are going to be eliminated by the unrounded corners, you begin to suspect that finding the valid 1 or 2 working solutions is going to be tough.

I experienced the expected almost solved situations several times.  The case where the last remaining opening for a piece matches a piece that was already placed and not the one in your hand.  And the case where the last piece in your hand would fit if only one of those unrounded corners had been properly made.

Of course, I started with the missing Z challenge since there were 2 solutions and it would be like finding 1 of 2 needles in a haystack instead of a single needle.  And sure enough, even though it took some time, I eventually found 1 of the solutions.  Challenge complete.  No, I didn’t feel compelled to search for the other solution.  It’s always there if my conscious starts to nag me but she’s usually after me to do other non-puzzle related things.

I did the missing L challenge next since T pieces are usually a real pain in these types of packing puzzles.   I found this one much more difficult than the missing Z challenge and it took a lot longer to solve.  In fact, I sat down with it several times without success.  I was relieved when the last piece finally went in to complete this challenge.

I saved the missing T challenge for last since I find that the T piece in 2D packing puzzles usually don’t work well with other pieces.  However, the T is so restricted in how it can work with other pieces that it actually supported finding the solution.  There isn’t much you can do with that T so it helped to narrow things down rather quickly.

If you like Messing a-round, Alexander has designed other puzzles where he’s forgotten to round the corners of some pieces.

Entwining Pieces – Collator

Where other people say, please make it easier to put things in the box, puzzlers dare to say, please make the box opening smaller with malcontent contents that don’t like to work together.  Entwining pieces within a box with odd little openings is alluring.  Divining the correct sequence to bit-by-bit, slowly transfer objects that coalesce totally intertwined within the box - puzzle nirvana.

Collator was designed by Alexander Magyarics and made by Brian Menold at Wood Wonders.  It was made with a Flame Birch Box and the 3 pieces that need to be crammed in the box are made from Bolivian Rosewood (one of my favorites) with some very nice heartwood accents.

Putting the pieces in the box is as easy as 1, 2, 3 – or I should say 1.2.3.  However, that is not the true solution.  There are 10 possible ways to assemble the 3 pieces into a 3x3x3 cubic space.  Of those 10, 3 of them can be packed in the box.  However, only 1 of the 3 looks like a solid cube when it is inside the box.  It is this apparent cube configuration that is the objective and it has a difficulty level of 10.4.2.  The other non-apparent cube solution has a difficulty of 5.1.3.

I really don’t need to tell you that this is a good puzzle.  Designed by Alexander, made by Brian, 10.4.2 restricted opening apparent cube packing puzzle – you know it’s going to be good without even seeing it.  And it’s even better when you get your hands on it.  With a box at 3 cubic inches and pieces with a voxel size of 3/4 inches, it’s bigger than most apparent cube packing puzzles making it a pleasure to handle.  The beautiful Bolivian Rosewood pieces also have a nice heft to them.  And no, I wasn’t disappointed and thoroughly enjoyed the sequence of moves required to solve the puzzle.

An Attractive Puzzle – MagneTeam

You either like or don’t like apparent cube packing puzzles and MagneTeam is certainly a polarizing puzzle.  This puzzle doubles down on apparent cube packingness, giving you that much more to love or hate.

MagneTeam was designed by Alexander Magyarics and made by Cubicdissection.  The box is made from Ash with a - shaped opening on one side and a + shaped opening on the other.  The Cubicdissection team thoughtfully beveled the 4 inner corners of the + opening for when you poke your fingers inside.  The 4 pieces to be packed are made from Granadillo and Morado.  Why 2 different types of wood for the pieces you ask?  Because there are 2 objectives.  The first objective is to pack the 3 Granadillo pieces into the box making an apparent cube (as a quick reminder, an apparent cube is a shape that looks like a cube but may not completely be or be completely a cube.  It just fills all the openings of the box and looks like one.  You can think of it as a cube wannabe/impostor/impersonator – you get the idea).  Once you have apparent( cubic)ly solved the first challenge, the second challenge is to add the Morado piece and pack all 4 within the box to make another apparent cube.  Since the first challenge was already an apparent cube, chances are that you can’t just simply add the additional piece for a quick win but I’m pretty sure that you guessed that already.

So what do you need to know to solve this puzzle.  On the negative side, it may be daunting if you’re not used to apparent cube packing puzzles and unaware of how to utilize small openings to solve the puzzle.  On the positive side, this puzzle has a big opening that easily permits pieces to enter the box.  Both challenges are fun and can be solved like most apparent cube packing puzzles.  No rotations are required but each has a nice difficulty level: 9.4.4.3 and 7.6.6.  

The biggest challenge for the 3 piece apparent cube was quite unexpected.  The Granadillo looks nice and the Morado looks just as nice, so much so, I couldn’t really tell them apart.  You say Granadillo, I say Morado, let’s call the whole thing indistinguishable.  Maybe it was a third challenge, maybe it was Eric Fuller’s sense of humor, but I spent some time trying to convince myself that one of the pieces was made from a different type of wood.  Of course I wouldn’t deprive you of figuring out which piece it is by mentioning it here.  Although if you are curious, you can check it on the puzzle will be played site.  For the record, I would have been perfectly fine if all the pieces had been made from the same type of wood with the challenge being to find which 3 pieces that still made an apparent cube.  

Two very nice challenges for the price of one.  Well done Alexander!
