The second solution was a bit more difficult, but due to Coffin's note about the pieces of the same color being parallel in this solution, it was quite a bit easier than I think it would have been otherwise. The third solution eluded me for a little while, but after playing with the other puzzles that John sent me, I was able to figure it out as well. Overall, a fun puzzle!
It is a nice looking puzzle made out of African Avodire and comes apart into six pieces (photo by John). There are three pairs of identical pieces. Interestingly, all of the twelve sticks that make up the pieces are identical. One pair contains just one stick each, one pair contains two sticks each, and one pair contains three sticks each. A very elegant design!
I played around with this one for many hours, probably approaching 10 or so. I kept going around in circles and couldn't figure out what to do with one piece that was particularly tricky to place. (I just noticed now that this is the same piece that makes up all of the pieces in Hextasy, I wish I had noticed this before!) I had a hypothesis for how it needed to assemble, but I couldn't quite figure it out.
Eventually I yielded and asked John for a hint. When giving me the hint, John mentioned that he and Stewart Coffin also needed a hint from Bill, so I didn't feel too bad. After getting the hint, I could see that I was pretty close. Due to the many hours I had already spent on it I was able to finish it up in about 10 minutes with this additional info. Phew! It was quite a relief to finally have this one back together.
Of the four, I think Hectix Revisited was my favorite. Four-color Hexsticks is a close second, I really like the multiple solutions, but it doesn't come together quite as nicely because there are three redundant notches in the design to facilitate the multiple solutions. Hectix Revisited has exactly as many notches as are necessary, which gives it a snugness that I liked. Plus, it was a real challenge!
A big thanks to John Devost for loaning me these puzzles, I had a great time with them. He is an excellent craftsman!
