I think that Twin CO is far less logical of a genre than I would have liked to see on an LMI test. I don't think that logic puzzles should be tests of visual acuity alone.

I'm quite surprised, as of the time of writing, that I've placed third on the LITS+ round. Had I been just 10 seconds faster, I'd have been first.

Had I known the Domino Loop and Hidoku were that easy, I would have done them earlier instead of trying to muster up the courage to plunge into them. I did however learn something from the Domino Loop about parity, and the breakins for the Hidoku, once spotted, almost made the puzzle solve itself.

The breakin into the Akari was well-hidden, and quite a bit of my time was spent wondering where it was.

Linked Poset Futoshiki is a pretty novel idea, but the rules were convoluted enough that I had to read the whole thing three times, and message Ivan about it in order to understand the rules.

Everything else was pretty ordinary but not noteworthy.

The Puzzle Marathon is always my favorite! It is so nice to be able to finish all the puzzles and get credit, and I love the big grids. The puzzles this year were very nice again, though nothing stood out as a particularly hard one .. I would rate most as easy or medium. And so I was mostly frustrated with myself for breaking each of the ESB, Galaxy, Futoshiki, Neighbors, Pentopia (I broke that one about 5 times, but it was one of my favorites nevertheless), and LITS+. Sigh. But a big thank you as always to the puzzles makers!!

Every single puzzle was excellently constructed, and even more impressively the difficulty seemed well-balanced between all twelve. I also thought that all of the rules changes for this year were for the best. Great job, everyone involved!

We thought it'd be nice to acknowledge some of the Marathon Solvers. There is some criteria for this list - We didn't consider solvers going more than 2 hours on a single puzzle, because they might have taken a break mid-puzzle. Also, the total accumulated break time in between solving is equal to or less than an hour.

I guess I should post a few comments about my puzzle (Linked Poset Futoshiki).

Congratulations for deu for solving Linked Poset Futoshiki the fastest at 12:29. Further congratulations for deu that has also won the entire Marathon. Also congratulations for Kota (15:50) and EKBM (16:03) as the podium finishers, along with those below 20 minutes.

Among the people so far that have posted their feedback publicly on this thread, 13 out of 49 liked Linked Poset Futoshiki. Since that's close enough to 1/4, I suppose I take it as good enough that my puzzle competes in the average. (I didn't actually count the others, so I'm not sure if there's any outlier).

Semax - 2016-04-04 6:02 AM

Now that I know the real rules of Poset Futoshiki, I am not very happy with the example. I thought that "X < Y" means I can only place numbers X and Y which are connected by an arrow. The fact that I can jump over numbers was not very clear.


Yes, this is unfortunate, and I apologize for that. I did have NEW, HUGE, AND CHALLENGING! that was hosted a month ago (about a hellishly difficult 16x16 Poset Futoshiki, but it also contains 6 practice Poset Futoshiki puzzles), but I think I forgot to remind people here to check it to practice Poset Futoshiki. (The linked part should be easier to understand.) For this particular question, I should probably have made a 2x4x4 example instead of a 2x3x3 one.

azrulnaut - 2016-04-06 9:02 PM

Hi, I'm new to this and I'm a little confused by Linked Poset Futoshiki. I see that there are 4 rules to this puzzle:
1. Assign one of the 3 diagrams to a small grid
2. Solve each small grid so each number appears once every row/column
3. Make sure all >/< signs are complied
4. Digits separated by gaps must be identical.

I get 2,3 and 4. But I don't understand no.1. How does the diagram relate to the grids? What do the diagrams mean?


I suppose it's no longer useful now that the Marathon has ended, but the answer below that post is correct. In a regular Poset Futoshiki (see above link), a puzzle is made of a grid and its associated diagram. In this puzzle, the diagrams haven't been associated to the grids; rule 1 in your numbering is to associate them (so each diagram is associated to one grid in each row/column).

bob - 2016-04-10 3:06 AM

The instructions were a little confusing to me--the arrows in the poset diagrams go in the OPPOSITE direction as the inequality signs in the puzzle.


A poset is usually represented as a Hasse diagram, which is exactly what you see: if there is a path from a lower number to a higher number that is going strictly upward, then the lower number is smaller than the higher number (and if there is no such path, then the two are incomparable). I chose to remain with this convention. On retrospect, it probably would have helped to remove the arrow heads and telling that lower number is smaller than higher number instead.

Linked Poset Futoshiki is a pretty novel idea, but the rules were convoluted enough that I had to read the whole thing three times, and message Ivan about it in order to understand the rules.


Yes, I probably should have linked NEW, HUGE, AND CHALLENGING! as described above, so that people can familiarize themselves with Poset Futoshiki first before going into the linked part.

Very nice set of puzzles. After missing last two years Puzzle Marathon, it was very nice and enjoyable experience for me. All the puzzles were very nice and has logical solution. Finding the same co-ordinates turns out to be very tough puzzle for me. Thanks to all the authors and LMI for this puzzle test.
