Can someone post the solution to Outside Killer, if the test is now over? I'm really getting muddled up somewhere, even though I feel I've used solid logic am getting a column repeat.

As for the test, some really nice Sudokus. My best rank on LMI, so I'm quite happy with my performance even though I can still improve(my classics speed is horrible, believe it or not I took 3 min each for both the 25 point classic and the 80 point Nonconsecutive killer [:s] ).

Results are public now - Congratulations to janoslaw for winning Best of LMI Mocks. motris is close 2nd. Nikola takes the third position and also wins Serbian Championship.

Rohan, Prasanna and Tejal take the top 3 Indian ranks.

199 players participated, out of which 173 players submitted at least one sudoku correctly.

There were way too many submission mistakes this time, possibly because there were so many sudokus (usually we have 12, but this time we had 18). There is some leniency in accepting typos which in other tests had been rejected straightaway.

Thanks to Zoltan for all his help before/during/after the test, and also to Umit for creating a nice logo.

I wrote the steps of sum or product frame here.
And it seems 10 for r8c123 and 24 for r789c6 did not be used.
Maybe it will become a harder puzzle.
I like the logic in Block9 that r7c789,r8c789,r9c789 only one is product.

Thanks, I got where I went wrong :) Silly error of eliminating the 1 in R6C6 for no reason.
