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.

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.

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?

Update - E-certificates sent

E-certificates have been sent to all official participants with non-zero scores. If anyone has not received an e-certificate, please let us know here.

Also, an email was sent to the respective top 10s of IPC and ISC requesting for their address in order to send their prize. The ones whose address was already given to the organizers (either as a prize claim or a certificate claim) weren't included in this mail, but for others who secured a top 10 Official ranking, this is another reminder about the same.

Tomorrow, all the participants who've ordered a hard copy of the certificate will be sent details to transfer the cost to LMI. Once transferred, the certificates will be sent to the given addresses.

Just for reference, here is a sample of the hard copy of the ISC certificate - https://logicmastersindia.files.wordpress.com/2014/06/2014_isc_rank_...

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.

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.
