Will it be possible to solve them online, like in the Mahabharat competitions?

Yes, online solving will be possible.

We always enable online solving when standard grids with usual rules are involved.

For the Renban puzzle, I think it would be good to have a precise definition of "group of shaded cells". The example requires cells which touch only diagonally to be considered as part of the same group for a unique solution. As the groups may not always be visually obvious, a tighter definition may help.

You're right. The instructions can be more specific.
But, we won't make any changes to the IB / PB. I can assure you the 'groups' are very clearly identifiable in the PB.

Please note that Unlucky13 starts earlier than the regular start time of LMI tests.

It will start at 10PM IST (GMT +5.30) on 31 March.

Going forward, regular LMI tests (unless explicitly mentioned otherwise) will also start at 10 PM IST - on Fridays.
(effectively 7.5 hours earlier than the current start time)

Are there any tricks to solving these puzzles? Aside from the fact that they are all classics, of course. The reason I asked is that for at least half of puzzles, I have got the answer keys by only solving part of the puzzle.

No tricks, maybe the AKs are badly chosen then. In general, for easy Classics its hard to chose good AKs since people tend to concentrate their solve towards the AKs and get them without solving much.
Anyway, this is just a fun sprint test :-)

Surprising and interesting! An excellent idea - especially the "surprise" sudoku ;-)
Thanks Rohan!

I wrote sudokuw like these before, so I actually knew from the IB that all the types could potentially be reduced to classics.
Given the test started 1st April, I was expecting exactly this, so I didn't bother printing them out.

Turns out to be a bad choice since solving online is much much slower :(

Oh well, happy April Fools everyone!

Finally scored full points for the first time. Took me almost 20 minutes to realise that it was all classics in disguise. Wonderful set of puzzles rohan. Was stuck in odd even for quite sometime . i think odd even took me the most time. Quite happy with my performance

Aside from struggling with resolving a few of the killer sums (my best type!), I found this to be a pretty brisk solve -- and amusing too. Thanks much Rohan!

All Sudoku's were nice.Starting 15 minutes of the test are quite good for me except the diagonal sudoku but after that I got breakdown in killer sudoku and done some silliness in surprise sudoku which I paid off as 5-6 minutes more to my timings.

This time few players from India only 65 participated since
from the IB its like full variant test but a suprise classic sudoku test.Its good if classic sudoku test like this difficulty held at least a month.

Best thing about the test is the password "LuckyYou".

All of the puzzles were extremely nice. After solving 2 puzzles, I checked all off them and got that all puzzles are classics and the most surprisingly was the 'surprise' one that was also a 'classi'c.
By the way happy to finish on 4th from India and first time in top 10 from India in any competition. Could make to the podium if did not do 'diagonal' wrong in first submission.
