No Problem Puzzles, Update #7

No Problem Puzzles provided over 100 amazing puzzles designs for the community between November 2020 and April 2023 until the tragic passing of Symen Hovinga on 7 April 2023.  Theo Geerinck, the other half of the No Problem Puzzles duo, decided to graciously allow the puzzle designs to be made available to the puzzle community for anyone to print their own copy to keep the legacy alive.  Mr BurrTools himself, Andreas Röver, is currently in the process of verifying and publishing the stl model files over the next several months.  These are being made available on the Printables site under the No Problem Puzzles collection.  Another contributor, Crab on Printables, has also tweaked some of the models to improve them.

This post continues the review of the No Problem Puzzles as the models are being released.  Since the last review (No Problem Puzzles, Update #6), more No Problem Puzzles have become available.

Squeezy

Squeezy consists of 5 pieces that have to be packed within a holey frame made from 2 identical pieces that slide together.  And the sliding is hampered by all the pieces that have to be stuffed inside.  Of course, this is one of those puzzles where you don’t have much to start with, find some things to hang your hat on, discover some key moves, realize what you had been missing, and end up saying - of course.  The things that I got right didn’t hurt me whereas the things that I got wrong led me astray.  In the end, after discovering some rather nice movements, I managed to get past my short-sightedness and strangle, I mean squeeze the frame together.  Squeezy provides a really good challenge for a level 3 puzzle.

I lied when I said that the 2 halves of the frame were identical.  One piece has the puzzle information debossed on it.  Ohhhh, is that a clue?  Maybe, maybe not.  But I did reverse the 2 halves after I initially solved it.  Make of it what you will.  Just for the record, my wife believes that I have no clue what clue really means and that I don’t give out clues because I’m clueless.

I Box

The goal of I Box is to pack 5 pieces within a box with a v-shaped opening.  It has the same difficulty rating of level 3 as Squeezy but is completely different.  For this one, I would recommend that you solve it before you solve it.  In other words, have a well defined plan when adding the pieces to the box since it is a bit fiddly to get pieces back out once they are in the box.  Especially since the pieces need to be rotated and enter/exit the box at a 45 degree angle.  Also, unlike Squeezy, it doesn’t have a lot of finger holes for manipulating the pieces - 0 versus 18 unless you count the opening.  However, I did find the solution much quicker and with a solid plan, manipulating the pieces into place was not that difficult.

Mecon

A truncated octahedron by any other name, such as macon, would look as wondrous.
    - Not Shakespeare

Macon is a level 3 puzzle requiring packing 12 truncated octahedrons, or macons, into a cubish form that can be displayed in the provided stand.  But wait, the macons are split in half resulting in 24 semimacons.  Groups of 4 are then reattached to make 6 semimacon tetraclusters.  Except the process was botched and they weren’t reattached where they were cut.  Of the 6 tetraclusters, there are 4 of one type and 2 of another.  It’s up to you to rejoin the unmated halves.  To make it a bit more interesting, not all semimecons are mated to lend it a more cubish appearance.

The puzzle is not difficult, but it does take some time to adjust to the geometry.  And having done it more than once, it didn’t seem to get any easier the second time around.

But why were the truncated octahedrons made hollow?  Probably because they make a cool pattern when the puzzle is solved.  But of course, now everyone is going to wonder if you place a space-filling cuboid in each mated center, would you still be able to assemble it?  I would go with no but they tell me you never no.

Multiplex

Multiplex consists of 4 square chipped tiles that need to be packed within a square tray.  In essence, you need to map the pointy bits into chips.  The description says that Multiplex is a level 2 puzzle with 196,608 theoretical combinations to try.  Not hard, just takes a long time to solve.  I don’t know how the number of combinations was computed, but lucky for us, it seems a bit inflated.  Disregarding the edge details of the pieces, I think there would be 12,288 combinations.  And if you’re observant, you can quickly knock it down to 3,072.  After that, you will certainly avoid trying every possible combination and only check the ones with matching edges to converge on the solution.  I appreciated the thought that went into this design that rewarded the solver with a significant clue in the beginning to avoid a lot of unnecessary and tedious tile swapping.
