Multidodecahedron - Tom van der Zanden
Nested Cubes - Tom Lensch
I enjoyed this one: you sort of need to think of how you are going to approach it, since there are a few different options. Do you start with the smaller box and work your way to the larger ones, or the other way around? It is a bit repetitive, but I still found it fairly enjoyable. At one point I lost track of the orientation of one of the boxes that I had decided on, and ended up having to start over. Oops! Still, I think it ended up taking me about 15-20 minutes.

One Circle - Two Circles - Diniar Namdarian
One big annoyance with this one was how easy it was to jam things up: it is pretty easy to accidentally start to rotate the center with only 7 marbles rather than 8, which causes problems. With practice, this could probably be avoided, but I encountered it quite frequently. Still, I liked that it was a fairly manageable sequential movement puzzle that I could actually make a good effort at solving.
Pack-Man - Chris Enright
Peanut Gallery - Eric Harshbarger
I made some pretty good progress, but got somewhat frustrated fiddling with the little pieces. I think it would have worked better if they were quite a bit larger. After a little while, you get to understand what types of moves are possible, and see how to clear the way for the move that you want to make. It was pretty tricky!
Pearson Puzzle Pieces - Randy Pearson
I didn't find it too challenging to figure out, I think it took me about 10 minutes, but it was quite satisfying dropping the last piece into place. One thing I noticed is that the final cube didn't hold together particularly well. Perhaps a frame, magnets, or just a tighter fit would help. Still, a fun little assembly puzzle!
Perplexing Palace Puzzle - James Dalgety
This is a nice feature, I don't like when it takes you too long to figure that out, since many folks will just give up. In this case, it is fairly obvious, so I don't feel like I'm giving much away. For the actual trick, I thought that it tried a bit too hard to be tricky: somewhat less trickiness would have probably sufficed.
Prickly Burr 12 - Peter Conrad
Because of this confusion, I peeked at the solution to figure out what I was trying to do. With that in mind, I still didn't have a whole lot of luck actually making the assembly since indeed the holes are allowed to face the outside of the solution. Definitely a good challenge!
Puzzle in a Puzzle Box - Thomas Beutner
There's a bit of a trick to this part as well, that I thought was a bit too difficult to discover, though I didn't spend a lot of time trying. I think if you actually go through the full process of discovering the trick, it will be a nice surprise.
Well that's all for today! Stay tuned for Part 6 tomorrow!
