I put puzzles in order about how I liked them and add my comment to explain why so:

1. Regional Battleships - There was beautiful logical solution. It was possible to solve it fast and fly over the grid. On the same time there were plenty of places where needed to think a bit longer but still found a nice logical path. It was just excellent and with nice outlook.

2. Statue park - Same thing as previous, very nice and logical path for me. I really liked the end part how last pieces combined together. The outlook wasn't so nice, than in battleships, but in a wider view it made sense.

3. Regional Coded Snake - It was a hard puzzle and I even might say that too hard, because if you give 60 minutes and even many top solvers aren't able to solve it within that time limit, then I think it's too hard. Still I found it enjoyable and I liked how finding the code came out to be an important thing in the middle of the solving. After that it was pure enjoyment.

4. Scrabble with loop - It's rank rised firstly because there was my name in there and secondly because despite of being very bad at word puzzles I was able to solve it logically. Yes, it took some time, but I enjoyed it. Ironic is the fact, that I messed up once and I figured out that I had messed up exactly when I used "Kota". Thanks to Kota I figured out that I must go 3-4 steps back and do it differently. And on the same gray square where Kota started at the first place, my name went through it :) Riad, excellent puzzle.

5. Meandering numbers - I think I made my best performance in that puzzle. It really went smoothly most of the time and I really like number puzzles, but I had to guess in one place. I really didn't find a logical solution there and that ruined the thing a bit. But the puzzle was nice.

6. Turning Fences - It was much about knowing the tricks Bram teached us last year. That's the thing with that puzzle. that's why it feels that part of the puzzle is solved by someone else and during the whole time you must use the same tricks. It's not very sexy puzzle type, especially with large grid.

7. Nurikabe - The problem with nurikabe is that you need intuition to solve it fast. You need some experience and it's very important to see where the large areas reach. And that's what I don't have. It's my cumblestone and it's not the first time. It just didn't feel enjoyable to solve it although it might be a good puzzle. Maybe I would appreciate it more If my time was without searching half an hour where I did wrong.

8. Fillomino - It was just a fillomino.

9. Summon - I think it's a great puzzle type, but it was too hard. The times of best solvers are showing that too. Maybe it was intended, I don't know, but it's really annoying to do a math with small numbers in a really large grid. It just isn't suitable type with large grid.

10. Hidoku - same thing. It's really annoying to do that counting. It drives a solver crazy. I think it would actually have been even cool if it was easier. But what's the point of doing large hidoku to make solvers do that mononotous counting from 1 to 400 and then you make it hard too. I felt really tired after solving it, but maybe that's what a marathon should be.

Some of the puzzles were way too hard - Yes summon I am looking at you - and didn't really make it possible for those to affect scores much for many players. I think the "1 hour" time limit may need to be different for the easy puzzles vs. the hard puzzles. Really enjoyable puzzles nonetheless.

Very nice set of puzzles, very challenging and of excellent quality, thanks to all the authors (particularly to Riad for using my name)

In reply to other earlier comments: I do not find anything wrong in the puzzle being hard. It's a marathon. The balance of the difficulty level is excellent.
What can be improved is the bonus mechanism. It is unfair that for at least 4 cases the 20th fastest solver has no bonus (in the case of summon even the SECOND fastest solver has no bonus!). I know that in the past there have been long discussions about the bonus mechanism. IMHO the rank bonus should not have any connection with the time bonus. also, in this case, perhaps setting a time bonus level different for different difficulty level of the puzzles (for example: 45' for the easy puzzles, 1 hour for the intermediate, 90' for the hard ones) could have been better.

At last,the Puzzle marathon has come to an end.I am relieved that I managed to complete the contest as I seriously doubted whether that would happen after experiencing the difficulty of some of the puzzles in between the test.The mental energy that I had to put into some of the puzzles to get them to completion was so tremendous.Also,I opine that the contest overall was skewed towards the harder side in difficulty.Some of the puzzles were so difficult....

It may be the marathon.I agree with that but personally, I feel that in a marathon, I should be intimated by the size of the puzzle rather than by it's difficulty.If the size of the puzzle is one thing that stands between the solvers and their quest for completion, the difficulty quotient in this test made that task doubly difficult.

I wonder what might have forced Nurikabe to be graded an 'easier puzzle'.Of course there is the standard argument which goes: puzzles are ordered based on difficulty and personal experiences may differ.Despite accomodating that statement,I would still have thought that it should end up in the hard category even if I were to say at the least.I found it extremely difficult to find continuous strings of logic in that puzzle.The logical continuation from a particular stage of the puzzle to the next seemed incredibly far fetched.I felt that the puzzle could have been more easier with additional givens to work with particularly given the fact that it was in the easier category....

On a positive note ,I was completely fascinated by the design of some of the puzzles especially of that of Regional Battleships.To be candid,right after solving the Fillomino, I decided that I would include it as my most favourite puzzle of the marathon but Battleships just totally took it away.The solve path in Regional Battleships was highly pleasing and the theme(5 all over the place! and the LMI design) and the aesthetics is just too good to describe in words!!Amazing puzzle!!.I plan to solve it again just to relish the piece of quality logic hidden intricately in the puzzle.I enjoyed solving the Fillomino too which I had described in an earlier post in the forum.The puzzle was enjoyable with the logic completely free flowing and should not pose much of a difficulty to solvers familiar with Fillomino.I had great fun solving the statue park puzzle too.The way in which the puzzle worked out in the beginning and at the very end when it came to placing the last 4 pentominoes was just a treat.

I enjoyed the marathon a lot although I felt that some of the puzzles were just unreasonably hard (atleast to me) and could have been easier or should I say
not that much laborious.

Finally,a mighty thanks and sincere felicitations to the authors for creating some quality puzzles and making this marathon 2015 a great contest!!

The scores were using 2014 scoring earlier; perhaps it has changed to 2015 scoring.

All of a sudden, all the scores have changed. I notice there is a new set of instruction for the calculation of the bonus.


I strongly disagree with this change for two reasons:

1) In my opinion, it is never a good idea to change the rules of the game during the play;
2) the "new" structure is much more skewed and by far more unfair than the previous one. Instead of fixing what can be considered a potential unfair score on the summon, unfair scores are introduced for practically every puzzle. For example, lets consider the score of the snake. The fastest solver (with 35'44") gets 100 points; the 12th fastest solver (with 59'48", so 24 minutes slower), gets 97.3 points; the 13th fastest solver, with 60'02", gets 50 points. The fastest solver only gains 2.7 points advantage over the 12th for an advantage of 24 minutes; the gap between the 12th and the 13th of 14" is worth 47.3 points. Crazy. And the same applies to practically all the other puzzles, except of course fillomino, and in lower extent to statue park.

I believe that this contests should finish with the same score structure with which it started; if there are some defects which need rectifying (and there are) there should be a discussion immediately after the end of the contest to discuss the changes to be introduced in the NEXT marathon (perhaps a poll between various options discussed). This discussion should take place immediately while we still remember what was good and what was not. If we wait until next year we will have forgotten everything.

In my opinion, too many of the puzzles weren't solvable within one hour for average solvers. Unless the puzzles are made easier, I think it would be a good idea for the bonus period to be extended to 120 minutes per puzzle. This would ensure that the rankings are more accurate for average solvers.

I do not understand why EKBM, deu, and willwc do not have score equal to 400 plus their bonus. The rest of the top 20 have bonus+400 as their score and I can't find what separates those three. In fact, it looks like they are the only three people for which their score and their bonus do not differ by a multiple of 50.

The "Bonus" field is the total bonus in 10 puzzles, without discarding the two worst. As of now, these are the only three players who have got bonus in 9 or 10 puzzles. So "Points" is not equal to bonus+400 for them.
