Thats a really vague question. Do you want tips on how to solve? If so, do post a specific grid on the forum where you're having trouble, and one of us will surely help. Do you want to know how to participate in the Classics vs Innovatives contest? Read through this topic - http://logicmastersindia.com/forum/forums/thread-view.asp?tid=381, I think it covers everything. If you still have doubts feel free to post again.

Nice test this time. I would have to still improve of a lot though.
Thanks to authors and LMI for organizing test and such beautiful puzzles. I really liked the innovatives and will solve the remaining later. :)

I was unable to print. Just i got blank pages. May be i used black ink only option. I submitted the answer for C3 in C2 .

Did anyone else face this problem?

You get points for this. Refresh score page.

I have been struggling to see any sudoku puzzles after I start the test ... There is no flash page to solve it in online mode available in the link,
http://logicmastersindia.com/M201208S/

However, I am able to download the pdf but since I don't have a printer, I cannot print it out and solve it. It's more than 20 mins already since I started the test and it's really frustrating not able to solve it.

Hi krisram, We had announced (here and here earlier in this thread) that there won't be any online solving this time because of some complex sudokus.

I liked most of the grids. Hit a road block in between, but got through a bit at the end thankfully.

Capsules is a great variation.

It has been appearing with different names for a while now. For example, it appeared as Odd Sum Pair in WSC 2008.

Absolutely beautiful and elegant puzzles, whether you are a fan of classics or innovatives. Thanks so much for this incredible test.

I have trouble with the killer sudoku in Instruction booklet. Looks like the font used for the cage sum (Swiss??) is not embedded into the document. I'm afraid it will be the same in the puzzle file. And I might have more things missing, this one is quite obvious.

Wonderful puzzles. Thanks!

superb quality from japan as always. great puzzles. great presentation. great format.

With no more players participating now, Classics vs. Innovatives is now over, and the score page is open.

Thanks for this nice set! After reading the IB I thought a few puzzles were a bit too innovative/ error sensible for my liking, but when you are a solver competing halfway the pack, you are allowed to make choices.
I had fun with the six puzzles I solved and also with the one that kept me busy for the last 24 minutes without succes.
The killer was my absolute favorite. Really a brilliant, narrow solving path! Took me a long time, but was very happy to complete it finally.

A bit more detail about my performance now - I started off pretty well, and made a mistake in inequality around the last bits of the solve and left it. Then Killer went pretty well, and I got my speed back with that. Around the halfway stage something went wrong and I was just staring blankly at the Capsule for 35 minutes. When I finally regained my bearings, I solved 4 more at the end, only to see that the Co-ordinates had an error, and looking at the other submissions, quite a common one. All in all, not one of my better days, so pleased enough with where I stand.

My favorites were Killer, Sum of them, Inequality, Irregular, Capsule in that order. I liked Co-ordinates, but it had a lot of different places to keep track of, so maybe not the best in a competition atmosphere.

Thank you for the very fun and challenging set of puzzles. I am always impressed by the cleverness shown by the authors, and this is certainly no different. I will single out the Greater-Than Sudoku among many worthy choices -- it was amazing in its construction!

As a Japanese, I'm proud that they provided an excellent set of puzzles!

BTW, I'd like to know the influence of difference in answer key: between this style (only 4 digits) and usual one (all digits of particular row/column).
Is there any hint from the result?

Thank you everyone for participating. 235 players participated, out of which 180 got non-zero scores. Congratulations to Thomas Snyder (all 16 puzzles, 95:54), Kota Morinishi (15 puzzles, 95:32), Tiit Vunk (15 puzzles, 110:20) and Jan Novotny (15 puzzles, 119:36) for topping this test. Kota was the fastest, but he made a mistake in one puzzle.

Here are some statistics:
- Most solved puzzle: (C1) Classic Sudoku was solved by 149 players.
- Least solved puzzle: (I10) Sum of Them was solved by 14 players.
- Puzzle with highest rating: (I8) Quad max-min has 9.33 points.
- Puzzle with lowest rating: (I2) Odd Labyrinth has 7.40 points.
- Most common wrong answer: 11 competitors sent "3619" in (I9) Coordinates Sudoku. 2 players missed bonus points by that.

I hope everyone enjoyed the test. Which was the winner for you, Classics or Innovatives?

I allways prefer to solve (and also create) new and interesting puzzles more than Classic puzzles (which I sometimes find boring). But this was not the case in this test. Authors did great job with Classics puzzles here so I can say the Classics were as excellent as Innovatives in the test. My favourite was Killer - really great "10 stars" puzzle.Thanks for the test!

Now when the contest is over..can some one please post the step by step solution to Sum of Them
I could not even get a start

The start (as far as I know) is the fact that 1 can never be in a cell with a square, and a 2 can be in such a cell only at the edges of the box, because it'd have to have 2 1s diagonally adjacent around it to make it work. This all helps in the top left box to get that 1 and 2 can't be in R1C2 and R2C1, so 3 has to be in one of them, because otherwise you can't have the sum of 2 numbers <9. So 3 is in R2C1, with 1 and 2 around it, and R1C1 has to be either 8 or 9 with R1C2 being 5 or 6. For the sum rule, it has to be 6, with 1 at R2C2 and 5 at R1C3. Similar stuff should take you through it.
