All sudokus were very good... enjoyed them all and yes they were on a difficult side as compared to other SM rounds... but very good mind boggling sudokus... We need such sudokus sometimes.
My favourites are antiknight, consecutive, and OE queen
Thank you Harmeet and Ramesh for such interesting sudokus

I had been trying to set things up for some days and had changed couple of browsers in the process. But the Start button does not show even for active running contests.
In some it says Plugin not supported and in others it does not even show anything. Could you please tell is it java applet plugin which is being used or something else like Flash?

These are nice sudokus; but in a competition, I think it is way too difficult.
Once the difficulty reaches a certain threshold, it becomes more beneficial to guess.
For example; hacking at the Antiknight and coming to dead-ends might still be faster than trying to find R2C5 (which I didn't see).
Or in my case, choosing one of the main early branches [2,4 in R5C1,R5C9] of the OE Bridge still allowed me to finish in time despite trying out all the wrong steps in the wrong path earlier on.

These grids would be fun to try to find logical paths to, but in a race, there's just no time for that.
Thanks for the puzzles again! Nicely made.

The set of puzles were quite good, though I felt many of the variant 9*9 puzzles were tough

Since I neither had a printer nor a mouse at home, i had to copy the digits for 9x9 sudokus and draw the grids for 6x6. That took a lot of time since I had forgotten to mark the answer keys and had to scroll up and down for marking them. I started with 9x9 classics . On the variants side, I started with consecutive , couldnt proceed after some initial digits. Then I was completely stuck in anti knight. To my bad luck , I broke the odd even as well. I even logged out when around 25 minutes were left. Then I thought of submitting the classics I had solved and also attempting some 6x6 sudokus. The test was definitely one of the hardest that I have seen in Sudoku Mahabharat.

I am seeing that SM2020 is on harder side except first round which was well balanced.
I genuinely feel that for this round is really on harder side specially, Antiknight which looked laborious to me unless I missed some obvious better deductions.
Overall puzzle qualities if I see are very good but may not fit SM theme.
Thanks Harmeet and Ramesh.

Really nice test, enjoyed the puzzles, puzzle quality was really nice, although I broke / got stuck on almost all the 9x9s and thus didn't score well at all. Hope to catch up in the last round a bit! Thanks Harmeet and Ramesh! Lovely construction :) also very heartwarming to see one more tribute to Shaheer :)
Thank you!

To start with we would like to thanks everyone who participated in the contest. We would further like to congratulate Prasanna Seshadri, Tiit Vunk & Seungjae Kwak for taking the overall top three places amongst the 337 participants and Rohan Rao, Rishi Puri & Ashish Kumar for bagging the next 3 positions amongst the 124 Indian participants.

We got mixed feedback regarding the quality of puzzles and their difficulty level. But overall, the general feeling was that the sudokus were hard. We agree. But our sole aim was to give good but challenging sudokus to everyone. Odd-Even Bridge-2 (9x9) has seen the least submissions. Interesting to note that the original Odd-Even Bridge-2 had lesser number of givens and while finalizing we decided to add few more givens to ease it. But still it turned out to be the least submitted Sudoku. The Odd-Even-2 (9x9) was made easier by adding more clues than what original was having because that is one variant which almost everyone likes whether the solver is a newcomer or an expert. While in the process of finalizing the sudokus for the contest we felt that Antiknight-2 (9x9), even though hard, can remain as it is. It was certainly hard but logically solvable and has some nice deductions which everyone will agree with. A walkthrough for solving the Antiknight-2 has already been uploaded in the site which will provide better insight to it. We felt that Consecutive-2 (9x9) was comparatively easier and can’t be compared with the difficulty of Antiknight-2. But, yes, with respect to points distribution it appears Consecutive-2 and Anti Knight-2 deserved more points than allotted. This is in the retrospective. May be we need collective results of more test solvers while point allotment.

Nevertheless, we will keep the overall feedback in mind and try our best to provide good and interesting sudokus. We would like to thank LMI for giving us the opportunity to author this round of Sudoku Mahabharat 2020. Once again we thank you all for participating in this wonderful event. Last but not the least, we would like to thank Rakesh Rai, who has been so supportive and patient to make this contest happen.

One more thing, though painful & heartening, we would like to remember our beloved friend and great Sudoku enthusiast, Shaheer Rehman, who is no more with us. But we will always remember him and hence would like to dedicate Anti-Knight 2 and Odd-Even Queen 2 sudokus to him. These are our favourite sudokus as an author of SM Round5 2020.

Thanks & Regards

Harmeet & Ramesh
