Is 0-5/0-8 Difference Sudoku a new variant? Shouldn't it be 1-5/1-8 since N can't be 0, or am I missing something?
The box with N=0 is like a "classic sudoku" box, with no circles, as difference 0 is not possible.

Thanks for both the replies, it confirmed my line of thinking. I wanted to be absolutely sure, being new to SM.
Also I accept that having 1-8 in the name may imply that each and every box must have atleast one circle, so 0-8 is fine

Require more information on the linked line sudoku...?
Which same order is to be followed across the line?

The numbers along the line in one grid are in the same order as along the line in the other grid, but from which endpoint of the line you've to look for this order is not predecided and is to be determined as part of solving. Please take a look at linked line example sudokus in the IB.

Very nice set of sudokus to finish SM for this year. I struggled on the AntiKnight 9x9, but otherwise it was a smooth and enjoyable solve.

Favourite sudokus: Linked Line 9x9, 0-8 Difference, XV 9x9

Thanks Harmeet and Gaurav!

Looking forward to the offline finals.

Wonderful finish to SM.
Sad that I couldn't finish it. But the Linked 17 pointer and the Antiknight 9x9 was a grinder for me. Took most of my time in those 2 puzzles. Other puzzles were smooth. My favourite was Difference. I really enjoyed solving that.
Thanks LMI and Authors for wonderful test.

Any particular aesthetic/symbolic significance other than emphasizing that it has indeed evolved from Classic sudoku?

A very nice contest to end SM.All sudokus were challenging and very enjoyable.Sadly, I couldn't do my best because of breaking sudokus far too often with minor errors and being engaged by guests for a couple of minutes at the start didn't help either.Ironically,I needed those minutes to finish the 2 left out 1 pointers.Arrghh frustrating.....I expect my score to fall out of Indian podium as there are many good and fast classic solvers from India.

To conclude, a tremendous contest superbly constructed.My favourites are 0-8 difference (12 points) and Anti knight (12 points)

Thanks a lot Harmeet and Gaurav for a very enjoyable round.

Thanks to Harmeet and Gaurav for some fantastic sudokus.The set was really a tricky one.I broke both the Linked Line 9*9 and the Differences 9*9 after spending arund 10 - 15 mins on each,and that effectively ended my contest.
I felt the Anti Knight was a monster and deserved more points.
Really good quality set,and a horribly disappointing end to SM 2019 for me.

No clear favourites in this round,although if i had to pick one,it would be the Linked Line 9*9.

The variant 9x9s were really hard for me; I got only the Antiknight after some guessing. It might have been unwise to start with all the Classics. I'm disappointed in my result, unfortunately.

In my opinion AK wasn,t worth so little points. It was a very tough puzzle. But there is a chance that I missed some trick there. Anyway the test was very nice!

I just loved this test. Kudos to Gaurav and Harmeet. I just loved the 0-N difference sudoku. Linked was time consuming but really well crafted. Great job guys.

I am thrilled that I managed to complete all classics and all 6x6 variants. I expected to struggle with the 0-5 but found the xv 6x6 quite difficult. I feel motivated by this peformance, usually I end each test with a vow never to attempt another !!
