Is puzzle 3 supposed to have 10s in the lower left and lower right corner? It didn't seem unique to me but worked nicely with those added. Maybe I'm missing something.

Thanks for a good test!

Puzzle Booklet updated

During a change in puzzle booklet to optimize some formatting elements, some givens were missed in a puzzle making it non-unique. This change has been rolled back and we have reverted to the earlier version at 2:55 AM IST (5 minutes prior to this post). As no Indians were impacted, this is the best solution possible at the moment. We apologize to the international participants who tried out the puzzle while it had multiple solutions. If you wish, we can remove your score from LMI ratings consideration.

Explained above. Apologies for the inconvenience. We request that this isn't considered in the puzzle quality rating since there is a best author prize this year! :)

I don't mean to be unappreciative, but I didn't particularly enjoy the mechanics of all the grids were one idea was repeated over and over -- it is funny once in a while but here it made solving quite repetitive and not so enjoyable. (Hitori 5 and 6, tents 8 and 9, loop finder 15, doors 17: each of them had a very nice and rather original underlying idea in principle, but in practice these grids were just not fun to solve). This is a case where trying to have original aesthetics / themes in the puzzle construction actually hurts the puzzle quality in my opinion.

Wonderful Test !!
Actually went smooth for being starter.
I completed 20 puzzles in 40 min but took like 15 min in just the Doors and BWG big ones.
At the end entering answer keys was little hectic.

My favourite was of course Doors Big and BWG big.

Thanks Rohan for wonderful test.

I was disappointed with the raster graphics on Black and White and Grey and on Tents (pixellation was really ugly to look at). Also, the interior grid lines in Doors were too dark and thick to be solved in the manner the IB suggests. I ended up drawing X's over borders that contained closed doors and perpendicular lines through doors that were open to create a network of lines. Perhaps slitherlink-style dots would have been better?

Thanks for a great set!

So, clearly there are a bunch of easy puzzles. I know it's for Puzzle Ramayan, though, so on retrospect it's fine, even though I was hoping for better.

My favorite puzzles were the two hardest puzzles: Doors 3 and BWG 2. There are several puzzles that are less than ideal: Numberlink 3 had very similar halves; Hitori 3 had a big frame that ended up not doing anything, just artificially making the puzzle larger; Tents 2 had an answer key that was completely independent from the trees (because the only two solutions before including the trees gave the same answer key); Tents 3 had an obvious solution (there were several other no-number Tents puzzles I've done that were more appealing than this); Loop Finder 3 also ended up just having an artificially larger puzzle size, although it's definitely an interesting parity problem; Doors 2 was extremely repetitive.

Answer keys were mostly good, although I expected "leftmost tent for each row" for Tents and "lengths of segments up until closed doors" for Doors. Whether puzzles are worth the right amount, I can't say since I blazed the test, but I think a few puzzles can have their values adjusted.

Anyway... Well, an okay start for the season. I hope it's going better forward, though.
