Top grid of Hitori. Is there a 2nd solution by colouring the opposite 5 in row 3? Is there actually a 3rd solution there by colouring the opposite 1 (row 2) and 5 (row 3)?

Yes, there was a mistake in this example, which was found by Deb at the last moment and I've corrected picture without checking uniqueness.

And you should have mentioned that it is me who suggested the 'correction' as well. Sorry about the blind suggestion.

PS : A wrong date was entered as the start time of the test, and 4 players have participated in last few hours. This has been rectified, but those players' scores will be valid.

The score page doesn't handle the extra time related computations yet. Please allow us some more time to make it complete.

The webpage is not showing me the start puzzle button at all or the timer...how do i start solving the puzzle and submit my answers.

Are you logged in on the puzzle page? If you're not, there won't be a start button yet. If you have three boxes to fill in name, password and country, you have to log in first and then the start button will appear.

The three boxes you are mentioning are also not displayed on my webpage. What do i do?
when i open this discussion thread, its showing me as logged in on the top right hand corner..." Welcome, supreet...", but not on the puzzle page.

I'm no admin, but as far as I have noticed so far, the forum and the test page aren't directly linked with being logged in. So it can occur that you are logged in on the forum, but not on the Test page. So to play a test, you have to make sure you're logged in on the Test Page (here: http://logicmastersindia.com/M201206P ). If there are no boxes to log i on that page now AND there is no start button, then you should contact Deb, as I have no better information available.

what is tghe pasword for the pdf????, am not able to open it

The password will be available when you log into test page and press "Star Seven Samurais" button. After the end of test (on June 19) the password will be available without logging.

As always thank you very much to everyone for an enjoyable set of puzzles - plenty to keep me going now!

The puzzles were all excellent as expected, but what was absolutely superb is the logo.
Thanks Andrey and Kate

the pasword for the pdf :F

I like the puzzles, but I have no idea with the YINYANG

Isn't it interesting why the admins / organizers / author didn't post the password?
May be they didn't have the password!

Respected Sir
I want to organise prelims of any kind of world sudoku championship at my college from 2nd to 4th of November at MNIT,Jaipur during our fest.It would be a matter of great pride for us.

Please do reply at viveknandwani2@gmail.com

Why is the Minesweeper puzzle showing 20 per each grid instead of 25 on the answer submission page?

Minesweeper costs 20 point for all solvers. 25 is the number of minus to be placed, not points.

Thanks for some amazing puzzles. I had no idea the overlapping grids concept could result in challenges like what we got here. Yin-yang and Fences/Slitherlink were probably my favorites.

Surprised (in a positive way) at my performance, given how little energy I've had to devote to puzzles in the last month.

Seven Samurais is now over. Results are as usual available here

deu had a perfect 7. He finished with 01:57 to spare. Several others came close, but had typos. ppeetteerr and nyuta take next 2 positions. Congratulations.

Out of 229 players, 157 players solved at least one puzzle (and 1 player was disqualified). Thank you everyone for participating.

Not very encouraging results among Indian players. Rohan, Harmeet and Prasanna take the top spots.

About partial scores : Given the nature of the answer keys, there were lots of wrong submissions. We believed that some of them are typos. So we have been bit lenient this time and awarded 80% to some entries which we thought are typos with some amount of certainty.

Thanks Andrey for all the effort you have put for the contest. Request you to share your thoughts about first contest at LMI.

ETA : deu's score is 815.63, not 815.91

Although my performance was pretty bad, I really enjoyed the interlocked puzzles; it is something like "1+1+1+1 is more than 4".

Thanks Andrey so much!

Congratulations to Hideaki, Peter and Nagata for taking the top three in this test. Thanks to all participants.
The durations seemed to be too small and after first participants I was afraid nobody could solve all puzzles. So I'm glad to see seven solvers with 28 submissions. But only Hideaki solved all puzzles in time and without mistakes.
It was my first test at LMI and I'm very impressed by Deb's efforts on holding it. He changed scoring system especially for the contest and helped me a lot in all matters. Thanks Deb very much.
I hope to repeat this experience in future and make at least one more contest here.

Yin-Yang is my favorite too. It was a first samurai which I prepared for Moscow Cup competition and it starts the idea.
My second favorite is Easy As ABCD - I had most troubles creating it. Every second clue added to the puzzle led into conflict with previous and I discovered new solving idea. Of course most clues in the final puzzles do not need for unique solutions, but puzzles so was hard enough.
Fences was the most doubtful puzzle - the loop at overlapped parts seems to break rules (it even not a loop :) ). But I think example gives complete picture of the idea.
