AAAGGGHHHHHHHH!!!!!!!!! Off with her head! The only puzzle that I left unsolved at RPP that tormented me was Guillotine (aka Harun) designed by Volker Latussek. Just when I thought that I had left all that stress behind me, a package arrived from the UK. Allard Walker, somehow sensing that I would be starting to recover from my traumatic experience at RPP, strategically mailed me a copy to arrive just in time to prolong the frustration. I’m lucky to have such good friends.
It turns out that Guillotine was Allard’s exchange puzzle for the Edward Hordern Puzzle Exchange at IPP39 this year. For those not familiar with the exchange, each participant brings up to 100 copies of a new puzzle design that has not been released in the wild yet, to exchange with the other participants. This year there were just over 70 participants, so each participant left with 70+ new puzzles. In addition, a copy of each puzzle is donated to the Lily Library at Indiana University, which now houses more than 34,000 puzzles, generously donated by IPP's founder, Jerry Slocum.
As I explained in A Decade of Puzzling – RPP 2019, when I got back from RPP, I had an epiphany on how to finally solve this bugger. Overjoyed to finally be able to validate my hypothesis, I eagerly unpacked Guillotine and began to arrange the pieces. Unfortunately, epiphanies are cheap and this one wasn't worth much. It wasn't even close.
Guillotine consists of 12 pieces that have to be packed into a 5x5x5 box. There are 6 planks that are 4x2x1 and 6 additional 4x2x1 planks that have 2x1x1 pieces added on each end (or you can think of it as a 4x2x2 burr piece with a 2x2x1 notch taken out of the middle). The box has a sliding lid that covers half the box. It only covers half to allow the pieces to stick out in the unsolved state that it comes in.
After giving up on my erroneous hypothesis, I called it a night to get some sleep before attacking it again. I resumed the effort again in the morning, and after a short time finally managed to find a solution. Very clever puzzle!
Peter Wiltshire mentioned that there were 2 solutions at RPP, a hard one and an easy one. I assumed that after all the struggling that I did, I finally managed to find the easy solution. After another 5 minutes, I found the second solution. Having both solutions, I’m now assuming that I found the harder one first and that’s why I found the second solution so fast after the first one.
The copy that I played with was made by Eric Fuller and went by the name Harun, which I assume is the name that Volker Latussek gave the puzzle. Allard’s exchange puzzles were made by ROMBOL GmbH, and I’m told that they sometimes change the names of puzzles for marketing reasons. So Harun became Guillotine. Either way, this one is a tough one to get your head into, or maybe I should say out of.
Thank you Allard!
Glad you enjoyed it, Ken! Personally, I think it's a bit of a b*****d! :-)ReplyDelete
Brilliant choice for your exchange puzzle. I confess to referring to it as The B*****d, but only in the nicest way possible.Delete
the original Name of that puzzle given by Volker LAtussek himself was Guillotine, because the lid of the box is used as the guillotine´s sword; the name Harun was used by E. Fuller;
Thank you for the interesting feedback. I would have to assume from this information that Eric didn't see the value of the Guillotine box lid and received agreement from Volker to release the puzzle without it under the new name Harun.Delete
I’ve solved it and I can’t shake the feeling that there is some connection between the solution and the standard 6 piece burr. Another interesting thing is to consider how the holes are packed.ReplyDelete
But I disagree that the puzzle is b*****d! Any puzzle that can be solved by burrtools is not b*****d.
Funny you should mention the holes. I determined how many holes there were early on and even assumed that I knew where the holes were going to end up. Even though I was correct, it didn't really help me.ReplyDelete
I disagree with your disagreement. If you drew a Venn diagram of puzzle categories, I would suspect that there would be a significant overlap of BurrTools solvable puzzles and B*****d puzzles. In fact, I have a sizeable collection of B*****d puzzles and I'm sure that several of them can be solved by BurrTools.
Fair enough! In any case, I don't understand why we are bleeping the word "Bandaid"! ;-)Delete
It's a sticky subject involving a cover up.Delete
