Today I have ODD packing puzzle. The name comes from the shape of the pieces which in fact spell out O D D. This puzzle won the Puzzle of the Year award at IPP28 and I am very excited to see what it is all about.
Holy shit these are big pieces! That was my first thought upon unwrapping this latest puzzle from Cubicdissection. And indeed, the pieces are big. Each of the “Square-ish are almost 2″x2″ and the box itself is 4″x4”. The rectangular-ish piece is almost 3″ long too. Those are some big pieces to cram into this big box. Is the large size a bad thing? Nope. I don’t think so. Does it enhance the puzzle? I don’t know yet – lets find out!
The first thing I notice is that the Square-ish pieces are in fact not square. The will slide into the box in certain orientations, but not others, thus one side is longer than the other. This will likely matter when solving and I’m certain that there will be a fair bit of manipulation and/or rotation going on when solving. Ok, time to put in a little work and see what can be discovered.
Ok, ten minutes in and I haven’t gotten very far. It has become quickly apparent that dimensions matter. Those 2 little square-ish pieces have very strategically bevelled edges and very precise dimensions that have made this puzzle anything but trivial to solve. At this point, I can get any 2 pieces into the puzzle, but not all 3. It took a few tries to figure out how to get the 2 squares inside, but it is then impossible to get that last large piece in. Seems reasonable that one of the squares will be the last piece to enter. But, that isn’t really helping me any. Lets see if another 10-15 minutes will yield any further results.
Yes! Yes ! YES! Boom! I’ve done it! And with a verbally shouted “YES!!!!” that awoke the dog from her slumber, I stand triumphant! Whew, that was pretty fun.
I went back to the puzzle for another 10-15 to see what I could see and I quickly discovered something about the large block and a previous assumption. Once I had this piece of information, I knew what had to be done. Suddenly the puzzle looked achievable and it was only a matter of time.
I now knew the order in which I had to insert the pieces, I just had to figure out how to get the first 2 pieces into the correct place. I tried and failed and tried and failed again. I used the bottom of the box to try to figure out this tricky move and still couldn’t do it. I decided to just sort of “brute force” the solution and was sticking the first two in at various orientations to see if something would budge. When it didn’t work, I’d try a different orientation. At some point, I remembered lessoned learned from a particular Pit Khiam Goh puzzle and tried again. This time, things moved the way I wanted them to and that final piece was inserted and BAM, it was solved.
What a fun puzzle! I can’t wait to share this with some friends and family and see how they do! While not overly difficult, this puzzle definitely requires focus and thought and feels great when that “ah-ha” moment arrives.
I can now adequately, judge the size of this puzzle and have to say that I am very happy with the choice to make this one “big”. It is very satisfying to manipulate these big pieces and I imagine that a smaller sized version wouldn’t have the same appeal. The loud “thunks” of these pieces falling into the box is very satisfying and given that there are only 3 packing pieces, this was a smart choice.
Zebrawood is an excellent choice wood for the pieces and it is joy to handle and manipulate these pieces while solving. The large size adds a nice heft and also provides a larger canvas to really appreciate the striking grains in this beautiful wood.
Overall, a very pleasing puzzle to work on and solve that I am very happy to have in my collection. I will definitely hand this one over to friends and family with confidence that they can solve it if they put their mind to it.

I would not have referenced ********* at all… It does amount to a hint.
thanks for the feedback. I updated the post to be a bit more obscure.
Well done. Thanks for listening. Now can I delete my comment, since it mentions something by name…?
I have edited your original comment to remove the puzzle name. Thanks!
Cool. I could not edit it myself, nor delete it. You done good. Excellent puzzles, both of them. And Casino. And 4L. And Pin Block.
I got this puzzle in the Philos edition and, unfortunately, they package it as a disassembly puzzle. For me, it was pretty obvious how to proceed, since the pieces were positioned. It was kinda cool, but I wondered why it had won an award.
I decided to get one from Eric when this edition came out and I was surprised when it came disassembled – even though I remembered the basic concept, it was harder to remember where to start and what to do – then I realized how brilliant it is.
I wish I’d been able try it without the “hint” of having disassembled it. I’ll pass along my Philos edition to a friend in an unsolved state.
Interesting – I’m not familiar with the Philos edition. Seems to be a bit of a blunder to ship it out assembled.
