The only complaint in an otherwise perfect test was that the 6X6 puzzles which were expected to be most accessible were a bit tricky.

The points suggested that they would be difficult, and I used trial to get past them quickly, but that is something which newcomers are not accustomed/keen to do.

I totally agree with amit, 6x6 were really tricky but it is justified to have spent some 20 plus mins on 100 points.. Overall a wonderful contest.

Congratulations to Prasanna for excellent performance and good luck to Indians in Beijing.

Ignoring the Screen Test, I think we have to go back 3 years (Mastermind Twins) which I organized and you participated.
You had spent so much time on Times Sudoku that I really didn't want to ask you to pre-test this one. Thank you so much for being there all the time.

I take this opportunity to thank the authors for providing some wonderful Sudokus.

Classic Sudokus, Sudo-Kurve, Thermo Sudoku, Arrow Sudoku - Thomas Snyder
Pinocchio Sudoku, Diagonal Sudoku, Killer Sudoku, Renban Sudoku - Bastien Vial-Jaime
Smashed Sums Sudoku, Vudoku - Serkan Yurekli

I am indebted to the test solvers - Bram, Gotroch, Matus, Nikola - who gave very significant input and feedback in a really short amount of time.

Thank you everyone for your kind help.

Indian Sudoku Championship - Results

The Indian Sudoku Championship is officially over. Both the official Indian Score page as well as the International score page are now public. 15 participants submitted all 24 Sudokus correctly, including 3 Indians.

Congratulations once again to the trio of Prasanna Seshadri, Rohan Rao and Rishi Puri for a strong showing at the top again. Prasanna's score of 1232.7 points was good enough to defeat the defending champion Rohan who scored 1181.2 points. Times Champion, Rishi, had a close 3rd place finish with 1158.1 points. Some good performances from the experienced contenders, Gaurav Korde and Amit Sowani, and Kishore Kumar showing a lot of potential with a solid 6th place, building on his good performances in recent LMI tests as well as the Times Championship. The International top 3 places were taken by janoslaw, Kota and daisuke_t. Prasanna finished at an impressive 6th place in the international rankings.

Thank you all for participating, and please keep visiting the forum for more puzzle contests and discussions.

Good catch. I think that somehow, the Instruction booklet's Outside Sudoku solution has been added here into this puzzle

Thanks for having organized a beautiful test.

Having sudokus from different authors permitted to vary the difficulty and styles. I think I recognized some authors' style while solving a few puzzles (especially kurve, renban, vudoku) but it should have been difficult to "authenticate" authors for all puzzles (I was surprised that the killer was written by Bastien, for example).

This test was a bit particular for me, because my grandmother died sunday, so I was not looking to make a good result, only tried to think of anything else.

Puzzles created by Thomas were really easy for confirmed players. Kurve, thermo and arrow were very nice for beginners or less experienced players, (as there are many for a national championship), and a good sprint for others. (I created a lot of classic sudokus last month, so I could not help noticing the lack of symmetry of the second classic, with 2 digits added on the bottom left. I think it was possible to make a symmetric one with that pattern, without adding the 2 digits, but it's really a tiny detail).

I even didn't notice the theme of the 6*6 irregulars while solving.

Nice construction ! Overlapping, shifted and deficit were nice.
Diagonal was a nice construction, with only 18 symetric givens without clue on diagonals and a nice pattern

. I liked the logic of killer and renban. I was not fast on smashed sums, but it had a nice logical path, too. GT consecutive had lot of non-consecutive logic in it.
I was stuck for a while in outside sudoku, but that's quite normal as it is worth 115 points.
Like Prasanna, I was stuck in the even killer, but after having spotted the 5 odds in the 1rst column

I wasn't able to find the 9 in R3C7, which was quite easy. So I lost at least 10 minutes on that one (I left it and finished to solve it at the end).

Congrats to Prasanna, Rohan and Rishi, Jan and the "pack of hungry Japanese players" and thanks again to the organizers !
