ISC 2014 is over, even for International Participants.

The result pages are all linked to here and here. Congrats once again to the Indian top 3 of Rishi, Rohan and Gaurav. Rishi has ended it on an impressive 2nd place Internationally.

The International top 3 were Kota, Rishi and Jaku111. Well played, all 3 of you.

ISC 2014 doubled as the Campionato italiano di sudoku. Congrats to the Italian winner, Giovanni Frugoli (Akuma21).

We hope all the new participants (and the regulars too of course!) enjoyed this contest. The solution booklet will be released tomorrow.

My general thoughts on picking the types for this contest was to categorize it in the following way -
Classics (1-4)
Smaller grids (8 6x6s)
A variation in presentation (Expanded)
Classic Lookalikes (Mirror, Irregular, Untouch)
Common variants (Diagonal, Odd)
Math variants (Killer, Arrow)
Relation variants (Thermo, Fortress)
Converse-Rule constraint variants (Consecutive, XV)
Uncommon variants (with "varying concepts" like distance (Search 9), heights (Inside Skyscraper) and positions (Descriptive Pairs))

Overall I feel ISC covered most of the broad categories appearing at a WSC and will surely prepare the winners well. At the same time I also feel it had enough classics to keep newcomers interested. I mainly followed Deb's format from last year which has proved to be well received for 2 consecutive years now. With minor changes, I think this is a good format to stick with. However, if the participants have any thoughts/feedback on this please feel free to let us know.

The individual scores of the Guess the Author game are attached.

greenhorn has the most correct guesses. Some entries are highlighted in yellow because these were just partial entries (only some Sudokus' authors were guessed). Bit surprised Bram is so low

The author details will be revealed soon.

And now the Author details, with the number of guesses for each author. Some funny stats: No one guessed that the XV is Bastien's. Fred's Classic style seems to be close to Deb's for some of you. The most accurate ones (with 2 or more guesses than the next highest number for the puzzle) were 6x6 Sudokus, Irregular Sudoku, Odd Sudoku and Descriptive Pairs (I thought Inside Skyscrapers would be my obvious sweep but it seems that was unanimously voted as Nikola's puzzle).

Hope everyone enjoyed this little added game. Thanks for playing.

The scores at http://logicmastersindia.com/2014/ISC/score.asp are incomplete (no USA participants for example), you apparently need http://logicmastersindia.com/2014/ISC/score.asp?mode=complete to get full results.

Just realized I forgot to link to the relevant comment in the forum in my summary above (added the link now), but this was mentioned before.

Wow! 7 correct guesses are fine, but I was pretty sure that Deb is the author of Classic sudokus and Nikola author of the Inside skyscrapers. By the way, I have never seen Diagonal sudoku by Zuzana, that really surprised me ...

Did the Instructions Booklet (IB) provide enough information about participating in ISC?	Yes, mostly.
Did you understand the Sudoku variations rules and examples from the IB?	I understood all of them.
Did you find enough easy Sudokus to solve during the championship?	Yes, there were many of them.
Did you find enough easy / familiar variations to solve during the championship?	Yes, there were many of them.
After your experience in ISC, are you going to participate in future championshiops or contests at LMI?	Most likely

The Inside Skyscraper Sudoku should have been worth a million points, since it appears unsolvable. Seriously, though, I have been struggling with it for a couple hours and have only placed 6 or 7 numbers (some 1's 2's and a 3) but hit a solid impenetrable stone wall. The other variants were quite fun.

One of the test solvers missed an important corollary here that doesn't apply to normal skyscrapers. This is the fact that the number which is placed in the cell with the arrow cannot appear in the buildings it sees. So where in normal skyscraper a "7" clue can "see" a 3 at the start (going to 3-4-5-6-7-8-9), in Inside Skyscraper, this cannot happen since the 7 is taken away from the buildings and can at most see (3-4-5-6-8-9). Once I pointed this out to my test solver it all fell in (still a work-through, but not impossible at least). Maybe this tip helps you too?

The Puzzle Booklet without password and with Solutions appended at the end is here.

Thanks for reminding me of that corollary...it did help me unlock the puzzle. Very challenging. And fascinating that a sudoku with just two givens and a smattering of random-appearing arrows can have a unique solution.

I did not get my certificate yet. Please provide at jagranihospitallko@gmail.com

Just checked, and I've definitely sent a certificate to this email address and can see it in my sent-mail folder. Maybe you can check your spam folder? If its still not there I'll re-send.

Is there going to be Times Sudoku Championship this time ??
