Reposting to make sure that everyone has read this post:

1) The LITS image in the pdf is incorrect. We have uploaded an updated pdf. So all participants who are yet to participate please download the updated version.
2) The Nurikabe 10X10 puzzle is incorrect.
3) The Numberlinks puzzle has multiple solutions.
4) The Heyawake marathon puzzle is incorrect.

Password for marathon pdf is different than main puzzle pdf. Both passwords will be displayed after you start the test


So for the Numberlink puzzle it means that any correct solution will be accepted and points will be awarded?
Or is that puzzle out of the competition like the incorrect ones?

Since you uploaded a new test booklet with a corrected LITS, are you going to somehow adjust the scores of those who completed the test before the new PDF was uploaded?

If you start the competition now, should you just skip the broken puzzles or are there still points available for these anyway?

We will consider points only for the updated puzzle booklet.
Points will be adjusted for all participants who participated in the test before the updated booklet was made available.

Results are published -
http://logicmastersindia.com/M201010P1/score.asp

We've followed a simple method
Nurikabe = 0 points for all
NumberLinks = 20 if player solved with old pdf and answer startsed with 1114, 0 if player solved with new pdf

This may not be the fairest way, but I guess there is no fair way to compute how much time a player spent on broken puzzle to compensate them for that.

We've disabled the ranks this time - you can sort by Points though.

Thank you everyone for participating.
And we (debmohanty, amitsowani, detuned) apologize again for the mistakes which could have been avoided.

There were 184 participants - 151 of whom got non-zero scores.

Here are some stats :
of countries - 35.
Top 3 (Based on #of non-zero entries)
Ind - 21
Japan - 18
USA - 16

Beginning of last week there were many new users registering from Japan that at one point I was thinking there will be more participants than Japan than India.
But Japan has highest Avg Score "754", and it won't be difficult to imagine how famous Nikoli is there.

Please provide feedback about the puzzles.
If anyone needs hints / steps to solve any puzzles, please don't hesitate to post here.

From the score page, it looks LITS is the least solved puzzle (okay, after the new pdf is uploaded)
No prizes for guessing the most solved puzzle - yes it is Sudoku!
P18 - Slitherlink was most incorrectly entered puzzle.

@Keshav : I assume you are talking about P06 Masyu, because that is marked as 0 for you. We are absolutely certain that the P06 Masyu is correct and has only one solution.
You can upload your other solution (in image format) in this forum.

Announcements

1. For HEYAWAKE in main section -
The answer key will be different that what it is specified in the IB

New Answer key: Enter the number of shaded cells in the 3th row, followed by the number of shaded cells in the 3rd column.

For the example the answer is 0,2

[...]



This post sort of tripped me up. Apparently, it was not the 3rd row and column but the ones specified in the PB. I guess I must have misunderstood, I actually had the correct answer until I noticed the huge red announcement in the sidebar. :D Oh well.

I've never solved Nikoli puzzles, and keenly realized the importance of experience.
Especially, Akari and Heyawake (which I couldn't solve within the time-limit) were thought to be tough for non-Nikolist.

Anyway, Thank you for the nice puzzles!
