Location: India | greenhorn's long post about Araf
So when Matus mentioned early last year that he wants to make an Araf for Marathon, I asked him for few samples of the puzzle, since I wasn't aware of it. Even after solving the samples, I wasn't sure how it will work in a big grid. But having worked with him multiple times in the past, I was certain that he will make a perfect puzzle for Marathon, and he did.
The hardest puzzles for me were Star Battle, Fifty-Fifty and Skyscrapers. I was not able to find out the logic of these puzzles, but it is just because I am not so versed in these types, so I solved them only by using brute force (guessing, guessing and one more guessing).
We listed Star Battle at the top of the list because of Star Battle's familiarity and the particular puzzle was not difficult at all (just focus on the 2X2X3X3 boxes). And for Fifty-Fifty, check Zoltan's solving guide which was posted in forum.
Couple of puzzles were made easier than their previous version, and I always wanted to upload the original versions. (That got delayed because I am not able to locate the pdf of original Masyu). But here are 3 others.
Nanro (After solving the puzzle in the competition, you might not find the original one much difficult. But I thought solving the original one first time could have been challenging. So we decided to add few hints and change couple of regions but the finishing with 8s remained as-is)
Mintonette (The regions belonging to 0/1/3 are same. All test solvers and me were finding the 2s region extremely difficult to solve. Considering its unfamiliarity, we thought might make the 4s region bit easy also. Thanks Fred for quickly revamping this one)
Fifty Fifty (The original version has fewer shaded triangles. I don't know if it would have made much difference to top solvers' timings, but from average players' point of view, it was good to have more shaded triangles)

I like the concept of one hour with bonus points and then "infinite" time for finishing later. I do not want to have this longer, even when I could finish some puzzles with only slightly more time. But so I know I have to reserve one hour and then I can do something else again. Exactly. That precisely is our motivation to restrict bonus to 1 hour. |

Location: United States | Enjoyed the puzzles I could solve during the week and glad that you made the rest available for those of us who couldn't devote too much time to solving. (I think one of my times was over 3400 minutes because I went to bed and then to work in between solving attempts!) Are the answer keys available anywhere? |

How is the alternate key for the Slitherlink retrieved?
I figure it's top to bottom instead of left to right. |

I didn't have time, this week, to do all of these puzzles -- such a shame. I will finish them off over the next little while. I really enjoyed the ones I did, though I got terribly stuck on skyscrapers in particular. |

Location: ITALY | It has been a wonderful contest. Better than last year because (1) the puzzles were more balanced and (2) the bonus mechanism was better. This is what I presume because I could not see a calculation of the bonus for each individual puzzle but only the sum.
Pity it came in a period in which I was very busy and in many cases I rushed a bit to solve some puzzle when I was a bit tired. In at least 3 cases I could not see the light and wasted a lot of time before getting through. But I am already looking forward to the next marathon.

When you open the score page, there is a banner with submission time. If you select points instead of submission time, you can see the score of each puzzle for each player and so see how much points/bonus you got for each puzzle. |

Location: India | Feedback page is now disabled. The top 3 voted puzzles are Nanro, Araf, Mintonette. The difference between Minotnette and Star Battle is smaller than that between Nanro and Araf.
We will try to include as many of the favorite puzzles as possible in next year's marathon, just like we did this year.
The overall score for Marathon is 2.75 which is much higher than any other test we had after we introduced the new feedback system. Thank you everyone for voting. |
