Pack 3 – Osanori Yamamoto

This week, I tackle the Pack 3 designed by Osanori Yamamoto and crafted by Eric over at Cubic Dissection. This one had me tearing out my hair, screaming into the night and storming around the house. My family was concerned for my well being and I attribute last night’s nightmares to this diabolical puzzle.

I’m clearly not very good at packing puzzles – in fact a majority of my unsolved puzzles on the shelf are of the packing variety. I’m not sure why they don’t click with my brain, but they are always a struggle – and Pack 3 was one of the worst (or best?) that I’ve worked on.

This particular puzzle is so deceptively simple and that may be what lead to my frustration. It consists of a beautifully crafted box with a unique opening along with 3 simple looking pieces. All you have to do is stick those pieces into the box. It should be simple, but it is not. The description says “The level 8.2.2 solution is satisfying without being too frustrating.” Well, I’d agree with the satisfying part, but for me, this was extremely frustrating, I dubbed it “the box from hell” along with other more colorful, non-family appropriate names.

This puzzle arrived along with 6 others the other day and I naively started work on it thinking – “I’ll start with the easiest of the bunch!” So, I casually began tinkering with the pieces, trying to insert them into the box. I spent 5 minutes here and 5 minutes there trying haphazardly to cram them all in. But, it didn’t work – furthermore, I couldn’t wrap my head around the idea that it required 8 moves with the first piece. How could that be? 8 moves seemed like way too many for the options I was faced with.

All you have to do is stick those 3 pieces into that box!

Within about an hour, I had a solution – only my solution was 2.1.3 and it left a visible gap. The solution didn’t feel right or satisfying and clearly didn’t match up with the description so I fired an email off to cubic dissection to see if I had done it correctly. The reply came back shortly after “You are close but that is not the correct solution.” Ugh, well on one hand I was happy to continue working on it, but on the other, I had hoped that it was correct. Back to the drawing board.

For two days, I worked on this thing. I was obsessed, I was driven, I was thinking about it in my sleep. I focused all my energy, I used all my logic and I failed over and over again. I decided to get systematic and try every possible combination of inserting the pieces, whether they were logical or not, I had to cross off all the non-working ideas and focus on what was left, but again, I failed. I cried, I cursed, I put it back on the shelf, but I couldn’t just walk away. I had to solve it.

One of the many ways to incorrectly pack the puzzle together.

And then, after setting it down and picking it up over and over, I finally saw the light. I was so in tune with the geometry of the pieces and the box that I literally solved it in my head while staring at it. Finally, I smiled and pronounced “I’ve got it!” And sure enough, just like that, I put the pieces in and solve this wicked and cruel little puzzle. The feeling was tremendous and the 2 days worth of built up tension was finally released. Ahhhhh. 

What a wonderful little puzzle! Yes, I wanted to burn it with fire and smash it with a hammer but now that I have solved it, I feel nothing but pure joy. It’s truly astonishing how many possible variations there are to work through. It is, without doubt, the most frustrating and rewarding 3 piece puzzle I’ve every worked on. I can’t wait to spring this on an unsuspecting friend. I will giggle with delight as they struggle with every possible combination they can think of. Awesome puzzle. Now… on to the next!

The completed puzzle. Beautifully constructed.
