Thanks a lot Rohan!A delightful test with some really novel ideas in solving and construction in particular.I had great fun!!

Thanks Kishore. I had predicted you would score 85 before the contest began :-)


Ah really? That's interesting.Next time,if you do, predict that I complete the test in 'X' number of mins :-p

Haha! Well, I can only predict in tests that I author! So, next year :P

 How well did the variants represent the theme of the test ? variations represented the theme well
 What was your opinion of the distribution of easy/hard puzzles? Too many hard puzzles
 What did you think about the puzzle quality of the test? Very nice
 Of the puzzles you solved/attempted, how well did the point values reflect the difficulty? Most puzzles were worth the right amount

How on earth are the small puzzles worth that many points? I solved quite a few of them quite a bit faster than I solved the classics.

I'm not quite sure what is trying to be achieved with the 50% easy, 40% medium, 10% hard distribution - the last few competitions have felt very disjointed with many puzzles you can breeze through before getting held up by one or two much harder puzzles. My personal preference is to have a much more even difficulty level.

This is to take nothing away from the individual quality of the puzzles - in isolation each was very nice!

Congrats to Kishore, Jaipal and Rajesh for the top Indians and to Tiit,Kota and Nikola for the top international players!
I really enjoyed creating this set, and personally liked it much better than most of my previous sets I've authored on LMI.

There is some feedback on sudokus being hard. Yes, that was intended. Since this is mainly targetted for the Indian audience, we are trying out different approaches to see how best to expose and challenge the players with different sudoku variants. When we initially started SM last year, we had a thumb rule that Classics should be ~ 20% of the points. It worked really well in my opinion. Now that we've changed the scoring system to normalize the points, tests can have varying difficulty without much effect on the score distribution of players across the rounds.

(1) Some of you voted for 'representation could have been better' -- Any comments on this will be helpful. Though, its likely the question is misunderstood :-)
(2) Many of you voted for 'too many hard puzzles' -- Totally understandable.
(3) Most of you voted for 'very nice puzzle quality' -- Thanks for that and glad you liked it.
(4) Few of you voted for 'many puzzles being worth too much or too little' -- I disagree here. If you look at the score-page and sort by # correct submissions, it is almost in reverse order of points. Which is the ideal scenario!

I also realize (4) can be interpreted in multiple ways:
-- Easy puzzles had more points and hard puzzles had less points
-- Very few puzzles contributed to large proportion of points and too many puzzles contributed to less proportion of points

I'm not sure what players are thinking while choosing this, but we expect the first one. Any feedback here will be useful. We might change the wordings :-)

Overall, I'm glad most of you enjoyed the puzzles. Nice to see 340+ participants with over 100 Indians.
Looking forward to the next SM round of 'Outside' by Rishi.
