The one thing I disliked was that there were two antisymmetric puzzles in this set: Untouch 2 and Extra Region 2. They are never enjoyable to me, because any deduction for one digit is also automatically true for another digit on the other side of the grid.

Really nice set of sudokus. My favourites are:

Extra Region 9x9
Diagonal 9x9
Quadruple 6x6

Thanks Hemant and Swaroop. Excellent stuff!

One small feedback on formatting: The extra region shaded cells are too dark in my printouts.

Thanks Kumaresan.

Congratulations to Jan Zverina, Seungjae Kwak and Tiit Vunk for taking the top three places. Also congratulations to Rohan Rao, Rishi Puri and Kishore Kumar for taking the top 3 places amongst the Indians.
Thanks to LMI for giving me this opportunity. It was a lot of fun creating the Sudokus. From the set my personal favourites were 6x6 Quadruple and 9x9 Untouch. And the Quadruple actually got most attention out of the entire set :P
Also thanks to Swaroop. It was a very nice experience of authoring with you. Apart from the sudokus you created, you also helped me a lot in making my creations better by your suggestions :)

Thank you for the feedback. This being my first time as an author, I have a lot to learn. And this feedback will surely help me.

Congrats to top 3 overall as well as Indians. It was great experience supporting Hemant. Its so good to see youngsters rising in solving and creating.
Sorry to Hemant if I was too strict mentoring(rejected lots of his creations) just wanted him to learn as much possible and create a good round.
I was very much aware of the half solve of Untouch 9x9 due to symmetry, but I let it through because I like his design and idea. Thanks to LMI for the opportunity and all testers.
Thanks to all participants and their feedback, will surely keep that in mind during next contest. I hope you all enjoyed.
Any participant if they feel they could not solve any particular sudoku, please feel free to post here we will be happy to help you.
Good luck with upcoming contests. :)

Generally, the 9*9 version carries more points than the 6*6 version of each variant. Is it because of the difficulty level of 6*6 is greater than 9*9?

The points are an indicator of the level of difficulty of the sudoku. So, yes; the 6×6 carries more points because of difficulty.
