Location: Indonesia | I can't edit it; out of time. :(
Comments for every puzzle! In order from the one I did first.
Heyawake
I chose Heyawake first because this cute dinosaur thingy told me about "an insane Heyawake". Or because of this, I don't quite remember (did it yesterday). So I opened it...and totally didn't expect it. Impressive construction, and indeed extremely evil. It took me 50 minutes to notice the opening (I had split the puzzle into three branches by then, bruteforcing at the wrong place), and midway I had to branch again; it was by a lucky guess that the branch I chose to work on is the correct one. I'm still figuring out a logical way here. Easily becoming the best puzzle.
Yajilin
As a nice break, I chose an easy puzzle. Here we have a cute easy puzzle with a blatant theme. At first I feared about missing a few clues (hard to scan rows/columns in a large grid), and indeed it's a bit tough but still quite doable. Puzzle-wise, there's nothing particularly striking, although it's indeed a smooth, easy solve.
Nanro
Of course I had to visit one of my favorite genres, Nanro. Unfortunately this one is the worst in terms of aesthetics (along with Mini Coral), so let's go to the solving path. The solving path is neat and varied, with plenty of tricks indeed. Nice one, but not quite memorable.
Turning Fences
Before doing this, I have found that given all the dots where the loop turns, there is either 0 or 1 loop satisfying it. (The proof is left for the readers.) So I was focusing more onto the dots, finding where the loop turns...before realizing that the loop gives another kind of deduction: if a loop passes straight through a dot, the other two segments aren't used. And there I just realized how Turning Fences is practically a very good mix of two puzzle types, with a regular switch between marking dots and drawing loop segments. I used mostly Minesweeper rules together with this rule...and got stuck after resolving about 5 rows and columns. And since I was sleepy and the timer crossed 60 minutes, I put it off.
The next day, I tried bruteforcing a bit (only about 3 segments!), and things fall through. Dang. Continuing with this solved all of the puzzle.
Probably the difficulty lies more in the unfamiliarity of the puzzle type, and the tendency to think numbers Slitherlink-style. Also, impressive theme; took me a minute or two to get the theme, all done while the timer was ticking...oops.
4x4 Sudoku
Nice theme here, with MARATHON at the top, although I was expecting more than just a random symmetry at the bottom. Also, this puzzle got the award for the most profanity I shouted while working on this puzzle, to find yet another undetermined 2/5 pair... No particular thing in solving path besides that one; the solve is pretty smooth.
Araf
Ah, Araf. The puzzle genre closest to Numberlink among all I know. It has scattered clues without much global theme, but I can identify the powers of two, the Fibonacci sequence, the complex of 7s, the 23456/454545 digit sequences... Local themes while still maintaining an interesting solve. A very varied solve here, with those random large numbers giving a good laugh. I intuited somewhat at the endgame, with the bottom-left and the middle unsolved, just like Numberlinks, but I think there's a good logical path around there which I didn't find in the pressure of time. Well done.
Statue Park
Hmmm... What is the theme... And when it struck me, I was delightfully amazed. The solving path is also clean, with a couple small bruteforces required but not hindering the quality. Of course, I have to botch the solve up somewhere in the middle after 15 minutes, leading me to redo the puzzle again to find the same failure before retracing carefully to find a fallacious assumption. And of course, the final "put these pieces without any black circle around" phase is impressive.
Scrabble
Oh hey Winter Olympics. Is LMI planning the Marathon to coincide with the Winter Olympics or the puzzle is designed around Winter Olympics because the Marathon coincides with it? :P This one I couldn't quite get a clean path. After the first half of the puzzle, I just randomly tried words that connect to the required letters, tweaking things until they work. The theme SOCHI and the five rings is neat though, so I suppose that makes it up.
KakurOH
I was expecting a large amount of large cells. Oh well. The solving path is nice, with only basic Kakuro tricks, although they have to be tweaked somewhat to accommodate the large cells. And yes, there are a few tricks by virtue of the large cells. Only symmetry, but I guess it's hard to squeeze in good visual theme with Kakuro, so well done.
...oh. Who says this is easy. It takes a good squint to figure out where the next part is, a bit like Hitori's observation part. But yeah, if you're told where the next deduction can be done at each step, the solve is very smooth.
Mini Coral
No theme :( This is the second Mini Coral I solved (the first was the example). I discovered some tricks on the fly. Yet I can gloat over my 21-minute time, beating Prasanna. :P (He said he has to redo the puzzle once. Okay, your problem for botching up the solve. :P ) After all that self-boasting, I'd say there's almost nothing remarkable of the puzzle. The ending with the bottom-right, however, is indeed remarkable, close to being a Fillomino or a Nurikabe, and I like that part.
Marathon
Regarding the marathon itself! It's impressive. According to the "five major genres of puzzles" by Dr. Sudoku (number placement, object placement, shading, loop, region division), if you can take placing words to be object placement, all genres appear twice except region division which is only one (Araf), replaced with another shading instead. (I take Mini Coral as shading.) That's perfectly balanced, even though I desire way more shading puzzles due to it being the easiest to do on Paint. The difficulty range is pretty much perfect. I'm missing some global puzzles (puzzles where the deduction is done by observing the entire grid; Palmer's 320 and 334 are good examples) here though; perhaps the large grid is just prohibiting, but eh.
Uhm, that's all from me. Whoa, that was lengthy. I took one hour. :O

I really enjoyed all of the puzzles; ranking them was somewhat arbitrary and I ended up favoring the more original types. I am not the best speed solver; I like to look for logic rather than trust my intuition. Nice inclusion of Olympics theme in the crisscross puzzle. Many of the puzzles seemed to be composed of smaller puzzles in the corners and almost a different puzzle in the center (especially araf and statue park) which added to the fun. I like large format puzzles and look forward to this contest next year. Bob Herceg USA |

This was a very enjoyable puzzle marathon in which to participate. Many of my favourite puzzle types were represented, as well as some that were completely alien to me, which is always a fun challenge. Thank you very much to all the craftsmen who designed the puzzles and to LMI for making it available for free. |

Location: Thailand | A little question about scoring.
Only the best 8 results count right?
So it is out of 400 plus bonus points.
Which means person A solves 8 puzzles no bonus = 400 points
and person B solves 10 puzzles no bonus = also 400 points
Am I right? |

Thoroughly enjoyed. Thanks to all the setters and for these puzzles and to all at LMI for this marathon. As usual, I made some silly mistakes. |

You have entered bottom-to-top. We mentioned top-to-bottom (and left-to-right).
In any case we have accepted your answer. |

Flunked the two 'hard' puzzles. Personally I thought Mini Coral was at least a medium due to its unfamiliarity and the puzzle itself being quite difficult.

Great marathon, thanks to everyone involved! It's really hard to pick favourites.
The Heyawake was too hard for me, but that's fine. I still need to solve that one properly. And apparently, I need to practice Kakuro.
If there's anything to criticize, I felt the dots on the Turning Fences were so large that it was a little hard to mark them for turn vs. no turn, and that some puzzles used a little more of an A4 page than my printer can deal with. |
