I still see no chance to get into one of the word search sudoku examples. Could anyone give me a hint how to start, maybe which word can be placed first? In the big one, I only got the "trivial" mini-sudoku-conclusions. In the 9x9 one, I only saw that "mocktest" has 3 possible positions and "sudokus" about 10 (I counted both directions seperate), both of course diagonal. Thank you... Silke

For the big puzzle, are you remembering that the whole grid is also a Latin Square? You should be able to assign all letters to the grids at which point the word search starts.

Yes, I know for every 4x4 sudoku, which four letters it contains. But after this, now I have to find a word which has only one possible place, or something like that, I think? And this is the point were I can't find something to go on.

For example, there's just one way to place NORTH (and to get there, only one pair of 4x4 boxes with N and H where you can find ORT between them). It helps to write down a 3x3 grid with the letters per box.

All password protected puzzle pdfs are zipped into a single file. The same can be downloaded from the submission page. Hope it is more convenient than downloading 12 different files.

One more short question. In Word Search Sudoku can a given word appear in the grid twice or multiple times?

Each given word has to appear at least once.

The puzzles actually were all reasonable in terms of difficulty. They were comparable with each other. Last year you never knew how long it takes and it was hard to plan solving them. This year it was nicely done.
I was also afraid a bit of the Twin Coordinates puzzle but it actually took about the same time as others - so perfect. Some got a jackpot with this but if you consider that you can throw 2 away, it's not a big problem if you fail this.
Anyway, cheers to the organizers for such a great competition. It'll be interesting to watch where I end up.

I think my copy of that puzzle was broken, it had just three twins. :)

Before the contest, I thought the scoring change which allowed authors to also skip two was unnecessary, but now I'm quite thankful for it!

Great puzzles! Thank you.

Now that I know the real rules of Poset Futoshiki, I am not very happy with the example. I thought that "X < Y" means I can only place numbers X and Y which are connected by an arrow. The fact that I can jump over numbers was not very clear.

But that's just a minor remark.

All in all it was a nice contest, I can't even choose my favorites, because each one of the puzzles was really cool.

Thanks to all authors for knitting together a beautiful contest . I greatly enjoyed the aesthetics and the solve path in all the puzzles with the exception of 1 or 2 puzzles which I hated. I also like this concept of slightly lesser difficult marathon puzzles enabling bonus. I hope this formula continues from next year .Thanks to Prasanna for helping me out with the example puzzles of Hex slitherlink and domino loop snake. These were new types to me and without solving the examples,I couldn't have solved the contest ones.

The marathon is becoming better and sweeter each year and this year was no exception !!
