When entering the coordinates of the cells in TWIN CO-ORDINATES, is there any particular order/format we must follow?

Order does not matter. We expect players to enter like J2 (i.e. first the letter and then the digit). You have to strictly follow the letters/digits given around the grid to determine the co-ordinate.

There will be as many boxes as number of pairs. In each box, enter the co-ordinate of any cell in the pair.

Order does not matter.
By "order does not matter", I meant among the pairs order does not matter. For the example puzzle, any of the following keys will be accepted
J2, J4
H1, J4
J2, I6
H1, I6
J4, J2
J4, H1
I6, J2
I6, H1

Right, it is Sudoku, not Latin Square.


I'm happy to hear that sudoku and latin squares became different again in 2016.

Twins Co-Ordinates - Any 5 pairs

We have decided to announce the number of pairs in Twins Co-Ordinates. While there will be exactly 6 identical pairs, only 5 pairs need to be found. The submission page will accept any 5 pairs. Players should submit as soon as they find 5 pairs.

Instructions Booklet is updated accordingly.

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?

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!
