Note: Some of you may have noticed that Amit Sowani was listed as the author for this round. Unfortunately due to time constraints he could not work on it. Fortunately, Nityant Agarwal filled in capably and we have another first time author for a PR round this year. We hope you all enjoy the collection that Nityant has prepared.

Also, forgot to say, points table will be announced in the next version of the IB closer to the contest.

Excellent contest ... had fun solving all that I could solve :)

Great set of puzzles Nityant, excellent job constructing these, especially given the circumstances. Happy to have been able to finish a puzzle round for once as well :P

Thank you professorX! Glad you had fun :)

Haha thank you! Glad you enjoyed them :)

Lovely set of puzzles! Enjoyed the Easy as LITS and Kurotto Connections a lot, and I'm glad I finished a contest for once XD. Great work Nityant.

Pretty interesting set of puzzles. Definitely really enjoyable one. Favourite ones were TAPA and LITS, and also Easy as LITS is pretty interesting puzzle type. Well, I believe all the estonians should love these because they are very popular puzzle types in here.
Actually the others were also nice and enjoyable - just with more boring puzzle names :)

The solving time of the top players is really impressive. Usually I'm somewhere double of the time comparing to the winner. But I think I understand how it works. At some point of your practice you get this intuition and enough knowledge and everywhere you find the solution really fast. I also felt that with few types, which were very easy and fast for me. But with the others you start slowly to do them and trying to understand them and time just flies :) That's where the big difference comes. And these shading puzzles are the ones where you can gain a lot of time if you are good enough.
But again, big respect to the top players in here !

Thank you :)

Thank you for the kind words, sir. I'm glad you enjoyed the set

Thank you for taking part! glad you like the set :)

Not sure if it was efficient but my plan of distributing solving between paper and Penpa worked kinda well :) Rushed through lower pointers on computer, did some of 6-8 pointers on paper in case I needed more notation.
Very fun and smooth puzzles overall. My favorites were Norinori 1, LITS 2, Kurodoko 3, Easy as LITS 2, Kurotto Connections 2.
Thanks Nityant!

Very nice set of puzzles Nityant. I enjoyed all the puzzles. Each puzzle was logically solvable without any guesswork.
Thanks for these puzzles. Looking forward to more puzzles created by you in the future.

Excellent set of Puzzles Nityant. Really enjoyed the test even though my performance was below par. My favorite sets were LITS and Easy as LITS.
Regarding Kurotto Connections 1 answer submission of 3rd column, I think I misinterpreted dark circle and treated alongside shaded cells. Not sure if it can be waived.

Unfortunately, the point of instant grading is that these errors get spotted and the solver has an opportunity to fix them, so I can't award points here.

I really loved the 3rd Heyawake, all Tapas and LITS (along with its variant).

Great work Nityant!
Hope to see more puzzles from you :D

Really enjoyed these puzzles, they felt very much human made which I liked.

Great set. Enjoyed all the puzzles.
Looking forward to more puzzles from you Nityant.
