What a Compass puzzles, absolutely brilliant :D

I agree.
The compass puzzle was really a brilliant one!

Awesome puzzles. Thanks to Puzzle authors and organisers for such a delightful IPC 2020.

A big thanks to the organizers for putting together the five rounds for this IPC. Each and every round was very enjoyable and had loads of memorable puzzles.
The points and time allocation for each round was spot on.

Special thanks to Rakesh, Priyam and Deb for putting in so many hours of effort and for the perfect execution even with limited support. (I hope I am not missing anyone out.)
Also thanks to all the authors for the fantastic puzzles. I will share my thoughts on the puzzles after solving the ones that I missed out during the contest.

Thanks to everyone involved for the amazing contest and puzzles! I had a lot of fun with this! :)

Beautiful Set of puzzles. Thanks to Testers, Authors, and Organizers (Priyam, Rakesh and Deb, and whoever else I might be missing). It was a day well spent.

Favorite among the puzzles I solved:
Round 1) Rassi Silai - That 6 was pretty tricky
Round 2) Compass
Round 3) Double Choco and Fuzuli
Round 4) IPC CrissCross
Round 5) Tapa Nurikabe (155 Pointer)

Thank you.

Enjoyed puzzles a lot. Will be doing left overs soon. We should have 5th round kind of monthly contest, it will help guys like me.
Big thanks to all organizers and authors and test solvers.

Brilliant puzzles, very well organized. I absolutely loved Round 5, and other rounds were great too. Like ISC, another great experience that gets as close as we can to mimicking an offline event.

Like Amit said, special thanks to Rakesh, Priyam and Deb for putting this together.

Lastly thanks to the authors for providing such a high quality of puzzles throughout the event.

On a personal note it would have been great to finish round 4, I was so close and I don't usually finish the casual round. Other than that, it was largely a smooth and enjoyable run.

Thanks to Rakesh, Priyam, Deb and all the foreign contributors for this fantastic IPC. High quality puzzles and just like the ISC, very well organized.
Really appreciate all the efforts in making these championships happen during a difficult year.

Congratulations to Prasanna and Swaroop for the podium and to Jayant, Gaurav and Nityant for topping PR.

Favourite puzzles:

R1: Pentominous
R2: Araf
R3: Double Chocolate
R4: Banners
R5: Ayeheya Yajikazu 2

Thanks a lot to the Organizers and Authors for such a wonderful puzzle rounds. It could not have been better quality puzzles. Enjoyed every puzzle.

Congrats to all the winners.

That was incredibly enjoyable, many thanks to all authors and organisers! A few comments on each round:

Round 1: All of the puzzles were very nice. Especially liked the Yajilin, Kakuro and Pentominous.
Round 2: The compass was a really stunning puzzle. Statue Park felt over-valued.
Round 3: Tough round; had quite some difficulty with numerous puzzles, including the domino search which I ended up effectively brute-forcing. The Kurotto was excellent and I also enjoyed the Aquarium quite a bit.
Round 4: A fun, different round. Hard to pinpoint favourites here. Was rather lucky to solve the 'three steps' puzzle in about 30 seconds.
Round 5: A bit annoying to solve on paper; ended up having to resort to coloured pens, which ended up working ok. Perhaps it's fortunate that the puzzles here weren't too difficult... I really loved the concept though!

Thank you to organizers Priyam, Rakesh and Deb for putting together IPC ! Fantastic set of puzzles ! Can't imagine the amount of work that must have gone in the background to organize another week of contest and special applause for that. Thank you to all authors too for creating amazing puzzles !

My story of the day was wasting the last 10-15 mins of each and every round by jumping from puzzle to puzzle or getting stuck on a puzzle. It started with Rassi Silai in Round 1 where I had 17 mins when I approached the leftmost region having 6 turns and could never get it to work . Spent about 15 mins on that and still couldn't see how to place it.

My favourite of the day was Ayeheya Yajikazu (100 points) from Round 5. I simply loved how the logic unfurled in that. Will look to solve the leftout ( and that's quite a few) in the coming days.

Regards,
Kishore
