Phenomenal performance by Nikola. I'm glad I competed even though there wasn't enough time left. Some of the puzzles took a long time to solve. Battleship Sudoku was tough, as expected. However, I also spent a very long time on Sequence Sudoku. Anyone got any nice logic for solving this one?

Hope to rate the puzzles soon.

Thanks Rohan. Good fun.

Aditya,
The future Monthly tests will not be this long.
We'll be having max 120 minutes.
Top solvers should be able to solve most puzzles in 80 minutes, and average solvers in 120 minutes.

@David
Thanks a lot :-)
Sequence was so easy! (The 6-cell sequence on the left has to have R2C1 = '1'. If you put R2C1 = '6', you will get stuck with R6C1. For the other 6-cell sequence, R5C5 cannot be '6' since '6' will be present either in R5C2 or R5C3. So, R5C5 is '1'. Then finish it! )

@All
Solution Booklet has been uploaded. You can download and check the solutions.

Thanks for this wonderful tournament !

It was a very nice concept. You had to know lot of variants to be in a good place.
Perhaps it was a little bit too long, but it was interesting to see how I can continue to be concentrated after 2 hours.

I'm glad to see so many participants and very happy to be in the top 10. I should have better prepared some puzzles to be in my top form (like perfect cube, perfect square and distances sudoku, which were not so tough, but I could not solve them during test).

It was interesting to see some tough 6*6 puzzles, and I like the fact there was a wide range of difficulty.

Thanks !

Fred

Thanks for a great contest!

I have a question about "EQUAL SUM SUDOKU" in Group2.
Solution in "Solution Booklet" seems invalid since
3+3=2+4 holds in R4R5C2C3. Does this puzzle have a solution?

Thanks a lot Fred/Hideaki.

@Hideaki
Yes, I missed the 'X' where you mentioned. Thanks for informing.
My apologies. I hope it didn't cause you (and others) too much trouble.

I don't have any other problem with longer Mocks. It is only that in our locality there is frequent load-shedding, and I don't have a laptop to overcome that problem.

I can only say that this was one of the best mocks so far.............CHEERS!!!!!!

Most of the puzzles were quite challenging and congratulations to the authors for coming up with nice ideas. Of course, the duration was a bit longish and did test "human concentration levels".

@Neeraj
Thank You very much! :-)

@Rakesh
You chose the wrong time :P (But yes, it was longer than a normal test)

Glad to know you all enjoyed the test! :)
