Rohan, there were some exceptional puzzles in here and you deserve many congratulations for putting together such a clever set! Rarely does a sudoku really get the mind working so hard for so long, and for the designs to be so nifty is a nice touch as well. Thank you for the set.

Having said this, I found the Missing Arrow EXTREMELY difficult/impossible/guess-y (as did nearly everyone else) and the Parted Arrow felt similar to me (although 25 people solved it so I must have missed something, as usual). Until today, I had never ever torn up the page in a fit of absolute rage upon finding an error, so that must mean something! :) It is uncommon for a LMI sudoku test to have what feels like many necessary bifurcation steps, and in that sense I guess I am surprised. Of course it's very possible I just don't see the logic-based steps...

Missing Arrow was tough and guesswork was obligatory. An interesting fact: Missing Arrow Sudoku is the least solved individual sudoku in any LMI sudoku test so far. So, kudos to Hideaki, Minfang, Murat, Thomas and Zafer.

I will say that both Sum puzzles were terrific. The first one had a neat killer feel to it, and I felt that a necessary step was one I had never seen before in an Arrow puzzle. The second one had such a clean path to its solution that it will be remembered. A pity I spent 30-some minutes hitting my head against the desk on the three puzzles that stumped me midway through the test, else I might've gotten some points on #2!

I had created 5 Arrow Sums Sudokus for this test and I had to include two of them. I think I chose wisely :-)

Thanks a lot, and I'm glad you enjoyed.

i wish i had not attempted the symmetric arrow which ate up my valuable 25 minutes in which i could have solved atleast 2 more . but the puzzles were really good. thanks a lot rohan for such nice set of sudokus.

Thats unfortunate, I'm sorry. Thanks :-)

Thanks for the fun tournament ! Very nice variations. Missing arrow and parted arrow made me completely crazy ! I lost a lot of time on these both grids and at the end I had some mistakes...
I've to solve these grids again and the symetric, which I have not yet began. Others were very beautiful and nice grids.
