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?
Sorry for the very newbie question, and sorry if this is in the wrong place. Found this puzzle via Reddit.
Lets look at the example below. By "diagram", we mean one of the trees (colored for your reference ).
So, each small grid (3X3 in the example and 6X6 in the actual puzzle ) will be assigned one diagram.
i.e. the "Inequality" rule in each grid will be governed by the "tree diagram" associated.
If you look at the solutions on the right, the top left and bottom right grids are assigned with tree diagram marked as "Maximum". Similarly, the top right and bottom left grids are assigned the tree diagram marked as "Minimum"
If something is still not clear, let us know.
What does this means
"Additionally, digits separated by a gap (between two adjacent small grids ) must be identical"
please clarify |

please clarify
In the example, look at the 3rd column of the first box and the first column of second box. They are separated by a gap and are identical. Similarly look at the 3rd row of the first box and the first row of the third box. Again they are separated by a gap and are identical. |

The Marathon contest is always my favorite of the year and 2016 was no exception. I really enjoyed all of the puzzles and maily chose my three favorites based on what had stuck most in my memory. I really did not think I was going to like linked poset futoshiki and did it last in case I found it unsolveable. 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. Once I made that leap, the puzzle was not only solveable with logic, but very fun as well and it made my favorites list. I remember Neighbors from Breinbrekers puzzle magazine and really like it. I wish I could find more of these. Same with Pentopia. All of the puzzles had lots of delightful aha moments and generally linear solves for me. My fastest puzzle was about 40 min and my slowest about 70 so they all seemed "medium" to me. My least favorite was probably the akari, it seemed a little guessy to me and I never developed a good way to do trial and error with pencil and paper akari (I usually just do Nikoli ones online which are much easier ), I kept entering wrong solutions only to later find a single unlit cell somewhere. Oh well. Overall, 10-12 hours very well spent. Thank you LMI. |

Choosing favourites is impossible, I really enjoyed almost all of them. The exception being the Twin: I like that it was included, I just had a really rather frustrating experience with it. Didn't even think I was that bad at such puzzles before, but I found roughly one pair per fifteen minutes, and decided to shelve it after 45. I think it was fine as is, but perhaps having to find more but easier pairs would have helped (me ). Other than that, a few too many mistakes, but overall a very fun contest. It was great to be part of it. The Akari is solvable logically by the way, though I can see it being a bit painful if you miss the central deductions. |

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. Edited by edderiofer 2016-04-10 1:46 PM

Enjoyed the contest. Congratulations to all the authors for creating a nice set of puzzles. I like the format: there is no time limit for each puzzle. |

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!! |
