Really nice puzzles with logical solving paths. Still, maybe I should have been a bit more intuitive here and there. :)
My favorites: TomTom 2, Top Heavy 1, Magic Summer 2, Top Heavy TomTom 1.
Thank you!

Set was very balanced in difficulty. Amazingly done!
Enjoyed Top Heavy (12) the most followed by Nanro (7).Thanks for the contest Rakesh. Couldn't have expected a better set !

Thanks to the 283 participants from 39+ countries.

Congratulations to Sam Cappleman-Lynes, Hideaki Jo and Nikola Zivanovic for taking the top 3 spots.

Congratulations to Ashish Kumar, Rohan Rao and Jaipal Reddy for taking the top 3 spots from India.

Thanks to Rakesh Rai for authoring this round!

Thanks to everyone who took the time to participate.

Stunning performance from Sam Cappleman-Lynes!. From the submission timings, it seems he got Magic Summer 3 answer key very very quickly (~3:38) and that made a huge difference. Amongst participants from India, Ashish Kumar turned up a very impressive performance - his approach of solving the puzzles in the reverse order worked well.

57 participants completed the set, with seven in the nervous 90s (and many on 84). So, it seems the set was of a decent approachable difficulty level. True to its name, Easy as 123 was the most correctly submitted puzzle - 240 correct submissions; and Magic Summer 3 was, as expected, the least solved - with only 93 participants getting it right.

Thanks for the feedback - Tiit, Rajesh, Rohan, Murat and Kishore. It was the first time I have created Nanro, Magic Summer, Top Heavy and the exploratory types. So the puzzles may have been a mixed bag. As noticed by Kishore, there was an attempt to balance the overall difficulty, although there may have been a skew towards some puzzles. There was an intended attempt to keep the puzzles easier - with inside givens in skyscrapers, lot of clues in Easy as 123, and small cages in tomtom and Nanro - and most participants breezed through them.

The initial version of puzzles had a 10x10 Top Heavy (Range 1-6), an easier / smaller Nanro 3, and less clues in Magic Summer 3. I think all the three changes worked fine.

PR4 is Regions by Swaroop. Looking forward to it.
