Always my favorite annual contest!!! Many thanks to the authors for the beautifully crafted puzzles!

I found the puzzles on average harder than in previous marathon contexts though, so for average puzzlers it was hard to stay under an hour for any of the medium/hard puzzles. As a result, the final score and ranking was very much determined by the easy puzzles alone.

Could someone give some tips on how to start the summon (once the competition is over of course)? I was very lost on that one and basically made no progress on it.

There should be no restriction when a puzzle can be started. Currently, when one puzzle is started, other puzzles cannot be started for some time period. The only purpose this serves is to remove options and cause annoyance for people with limited time.

Great puzzles! Especially liked the Hidoku, Fillomino, and Statue Park. I'd say the Summon and RC Snake seemed too hard for an LMI contest, but they were fun anyway.P.S. I don't think the score sheet is sorting my 11315:21 on RC Snake correctly :P

One way to fix this issue would be to have incorrect answers add time to the clock instead of just giving a penalty. That way if people really want to skip puzzles they've already started, they could just submit incorrect answers until the timer is over an hour, as opposed to waiting however long.

There always have been a 1 hour wait period before one could start a new puzzle.
But since it is last 24 hours, the wait period is removed.

Thanks for your feedback about the regional coded snake. :) i never thought it would be so hard to solve it. being first puzzle contributed in LMI website for a competition, i was excited to make it something different and quite tough, but it went out to be more tough than i expected :) I will see to it that it never happens in upcoming future test. Thanks for all of your feedback :)

Nice puzzles. I thought Nurikabe was easier. The most puzzle I like is Summon even if it was hard, the least - Snake, I hate snakes, even more like spiders than those ba******. :) Can someone post the solution for this? (it can be priv message) After 2 hours of tortures I've got this http://i.imgur.com/PCQgIXt.jpg and wanted to throw my computer out of the window. Yeah, I know about the mistakes at the bottom and on the top...

The puzzles were all quite nice in the abstract, but the difficulties were poorly calibrated.

RC Snake was clearly a difficult puzzle, not a medium one, and Summon was just a monster (I broke it 3 times, but even after I understood my mistake it took me about 3 hours to work through it).

I would like to side with those who suggested that, in future years, the cut-off time for difficult puzzles should become longer than 60 minutes, or one should still be able to earn some bonus in some way for performing well. I am reasonably pleased with my time on Hidoku, and to a lesser extent on RC Snake, but rather disappointed that the scoring system doesn't make a difference between solving in 75 minutes and taking many hours. (Of course, if I had done really well, neither of those would have taken an hour and I perhaps wouldn't be complaining as much :)

Also, I know that's a very unfair/specific complaint but, as the author of a puzzle that was more carefully calibrated in terms of difficulty level, I feel very slightly annoyed that I only get to discard my performance on only one of the insanely hard puzzles rather than two of them like almost everyone else. That could create an incentive for authors to create hard marathon puzzles rather than easy ones :-) just kidding.

Upon reflection, I think both the original scoring system, and the revised one for 2015 (is it implemented?) are both pretty bad. If you look at it by rank, I got 32nd place on the summons, and 61st place and 86th place on the Meandering Numbers and Regional Battleships. Yet, the former is being marked as my worst one, and got bonuses on the latter two.

I think we should just use the top ranks to determine the bonuses as suggested by debmohanty. If there is a need for players to know when to give up, set a long cut-off time for no bonus, after say 3 hours, presumably after the top competitors would have solved the problem.

The restriction on starting just one puzzle at a time seriously detracts from the enjoyability of the contest. Participants should be in charge of their choices and times. Anyone who wants to play for bonus time is free do so. A starting restriction forcing everyone to play that strategy is unwelcome.

The 2015 system was implemented ( http://logicmastersindia.com/2015/03P/score2015.asp ), it has definite problems as pointed out by Stefano.

The key at this point is to realize that that there are thirteen different letters that must cover the numbers 1 through 13. Once you realize which letters have to represent "1" and "2" the rest of the puzzle follows pretty smoothly.
