I am a beginner and my opinion is not so important for the general good of the game, because I would never became a representative player. Also I am not a fast person in any aspect so probably I will never be a fast solver, even let assume experience in the end will give me some improvement. Still, I feel most of the tests are build on a difficult or very difficult side and the target diistribution of puzzles (mentioned in the feedback form - 50% easy, 40% medium, 10% hard) is not respected in most cases. Maybe I misjudge the difficulty and maybe this kind of tests are excellent for the top solvers - which is good in perspective of National & World Championship.
Did you tought of a B-division kind of? I mean something like a preparation stage for medium or beginners solvers? Maybe this is not a purpose of this project, in this case my question is pointless. And I am not an Indian player, maybe this is also biasing me and is not relevant. I am just curious how you, the experienced players, see this matter.


Firstly, we value opinions and feedback of all the solvers here and if anything encourage more of them. So thank you very much for your thoughts.

It is generally difficult to know how easy to go and how much to go towards the other side. Just for example, define what a "beginner" should be able to solve here. Any definition you give will probably be discouraging for someone who solved less than that. So we can't possibly say that we target that a beginner should be able to solve this many puzzles - everyone is different in their development.

So the most important thing we target is - there should be something for everyone while also being a bit of a challenge for the top solvers. What a first time solver should aim for is to solve what they can, get some points and then solve the remaining puzzles outside of the 90 minutes to prepare for next time. Look at Round 3 vs this round or Round 1. Round 3 was objectively easier than both the other rounds, but there are many beginners who still got around the same score. The target distributions and feedback on difficulty are probably more useful for our authors, many of whom are also new and learning as the solvers are, to see how their round is received by different people.

So what is the solution? Well, not many do it but we do encourage asking for solve paths and tips for the puzzles after the contest too. Its a bit difficult to prepare full walkthroughs but I am sure there are enough people on the forum to answer about the next step or approach if someone is stuck on a particular puzzle - these are the discussions that should ideally dominate the forum over whether a contest is suitable for an audience or not, in my opinion.

Rather than try to make contests easier and easier which becomes a never ending endeavor, I would prefer letting the authors of Puzzle Ramayan, some newer and some experienced, to express themselves within slightly broader parameters, and instead focus on teaching solvers who are interested in seeing the logical paths of these and other puzzles and helping them raise their level through that. Some comments do make it seem like we are taking the puzzles away once the 90 minutes are done which I'd just like to remind everyone, isn't the case :) We keep a restricted forum for the contest duration for a reason. We are here to help solvers once the contest is done for them too.

Eventually this round and other PR rounds should also work as worthy qualifiers to the Indian Championships - which have both sprint rounds as well as more think-y rounds. We will surely consider all the feedback here. Thank you and everyone else for providing it.

Thanks for the puzzles, glad to finish this in time. Phew.

The 7x7 Skyscrapers was hardest for me.
The IB had a blank cell in Anglers so I thought that would apply to the puzzles here too - hence I wasted a few seconds
adding up the Anglers to make sure there were no gaps (and there were none). And made quick work on those.
I took around 2-3 minutes for the 8-point Anglers (compared to 10+ minutes on the Skyscrapers) - so not sure how others found the point balance there.

The Magnets (both classics and the variant) were very nice. I think I managed to find the intended paths and they were pretty.
Thanks again!

The quality of the puzzles were Awesome. I really liked the logic of each and every puzzle. The test was quite hard but enjoyable. It does not seems to be your first round Priyam :) Prasanna is one of the best authors so no need to mention him ;) .

unfortunately i solved 2 magnet puzzles and did not type the answer key. 14 points less from the total score :(




Thank you so much Ashish! Means so much coming from you! :)

As a lockdown exception, I participated in this round. Superb puzles. Quality and logic was amazing.
Of course as others have already stated, its definitely hard round. I broke skyscraper 7 pointer and Hashi 10 pointer at the end. Could have been 17 points more.
Didn't get time to even touch Magnets.

My favourites were:
Skylines and Magnetic Fields

Awesome Job Priyam.
Quality was excellent though difficulty was hard.
Thoroughly Enjoyed.


Glad you made an exception for our round :D
Thanks a lot, Swaroop! :)

Fantastic puzzles, great quality.
Laptop shut down midway for some reason,and wasted ample time to boot it up again.
The difficulty level was pretty high for me, as even the medium pointers took too long to fall.
Loved the anglers 8 pointer especially and the magnets set. Slitherlink was a good solve as well.
I feel answer key for magnets can be kept as P,N rather than +,-.
Thank you Priyam and Prasanna !


Ah the electronic misfortune! Great job anyway! Thank you so much, Pranav! :)

Very nice test as usual! Thanks for putting this together.

I'm not a huge fan of the magnets answer key because you have to alternate between holding shift for + and not holding shift for -. Could we use P and N instead?

Favorite Puzzles:

4 Skyscrapers - I like the almost symmetric grid.
12 Anglers - The 2x2 blocks of fish made the solve interesting.
19 Skylines - This had a lot of loop / skyscraper interaction.
22 Magnetic Fields - I like this variation a lot.


As a first time author, it's surreal to see postive feedback on puzzle quality from some amazing solvers and some of the best puzzle setters in the world! Thank you so much, Walker! :)

Had some trouble with big hashi. Also hoped to finish the set and it was close. In general nice and logical puzzles.

But the points distribution was a bit off for me.


Super close!
Thank you for your feedback, TiiT! Means a lot :) glad you enjoyed the puzzles

Very nice set of puzzles! Can't think of a puzzle I didn't enjoy.

I just think some answer keys could have been friendlier:
-Admittedly tents uses number clues but I still think number keys would have been better.
-Hashi keys were of different lengths but the red border for each line goes away after (I guess) you input the minimum length (for example, 6 for the large one). I was typing looking at the screen and got a bit panicky as I thought I had overly long answers. Also, not requiring zeroes might be an improvement, I corrected a row with an extra imagined zero at the last second.
-Allowing P&N for magnets would be nice.

Hopefully I don't come across as nitpicky, as I really liked the puzzles. My favorites are 12, 18 & 20. Thanks Priyam and Prasanna! :)


The first 2 lines made my day! Glad you liked the puzzles, and thanks a lot for the feedback! Means so much coming from one of my favourite puzzle authors!

Thank you, I'm really glad you liked the puzzles in this round! :)
Skyscrapers are my favourite and best type and probably why I cannot gauge the difficulty accurately! Thanks for the feedback Tawan!

Thank you everyone for participating, and again thank you to everyone who provided feedback on the round.

Like last year, I got to work with a debuting author. Authors maybe don't have as much leeway as solvers do :) While a solver can take multiple rounds to improve, an author has to hit their stride pretty quickly. Like last year I think the debuting author really did that in terms of puzzle quality.

A lot of you liked the 3rd Anglers and the Magnets set - these were my favourites of the set too when Priyam first sent them to me.

Last year's "rookie", Harmeet, returned this time for PR Round 2. I hope Priyam is a returning author too.

Its always a rewarding experience to see a new author find their steps and grow in confidence after a few initial tries. I hope I can continue to guide new authors into this in future years too.

Congrats Priyam, and well done :)

The round seemed to be on the hard side but as I have said above, this may be the opportunity to learn to solve harder puzzles and we welcome any posts of doubts and queries for approaches to the puzzles on this contest.

Thank you all once again for participating :) Over to Amit and some Casual and Word puzzles in Round 5!

Hearty congratulations to all those who topped the charts, and thank you to all the participants, so many more than I was expecting!

Thank you so much for summarising the results, Prasanna, it's been an absolute delight to work with you!
Prasanna's mentoring has been invaluable to me, and I cannot believe I've learned so much so quickly, all thanks to him :)
It's very encouraging to see positive feedback on puzzle quality from solvers and authors that I admire so much! I agree the round was on the harder side, and I hope to take the feedback into further authoring opportunities.

It's been a very unique and wonderful experience co-authoring my first PR round, and I look forward to many more!

A special word of thanks to Rakesh for putting in so much work into organising and facilitating the contest. Getting a close-up view of all the works really makes me realise how much effort and care goes into putting together contests like these at Logic Masters India!
Much love to all the admins!

Thank you all :)

Eagerly awaiting PR round 5 (Casual and word) by Amit!

I don't understand why letters are used for columns: using numbers seems like a better option.
Tents: Quite a few opinions emphasizing that the column number should be 123 instead of ABC. The main reason is not to cause confusion with tent clues. We agree that ease of entering is better with 123. So this can be considered next time, ensuring visually that there is no chance of confusing them as tent clues.

WA1729 - 2020-04-18 8:06 AM

OK. We can consider both options in future.

Grizix - 2020-04-18 9:44 PM
Maybe its just me, but I find answer keys with letters for the column numbering (instead of numbers) really painful.
And I cannot see the point of having to put letters instead of digits.
The digits are ordered, and the letters are thrown on the keyboard randomly, so I have to put one hand on the grid to check the alignment with the top letter, and the other hand on the keyboard, trembling from one letter to another, eyes staring wildly to find the good letter.
This point has been answered already.

kishy72 - 2020-04-19 5:43 PM
Entering answer keys were a chore.In particular, Hashi's was very difficult to enter and I kept putting more digits than needed in the answer key due to wrong interpretation until I figured how it works.Maybe specific clues can be marked above by a letter and asking the number of clues connected to them would have been better ?
Not sure if that would work better. We considered the current key as against "number of double bridges" as counting is too error-prone and maybe guess-friendly too.

pranavmanu - 2020-04-22 1:35 PM
I feel answer key for magnets can be kept as P,N rather than +,-
Magnets: The advantage with + and - is that we enter the same characters that we used during the solve. Also, + and - are next to each other on the keyboard. Probably we can allow both options next time.

A Carton Mutant - 2020-04-22 8:45 PM

Hopefully I don't come across as nitpicky
These are good points. And if it is called nitpicking, that is welcome. Good observation on the Hashi key. Yes, the red border goes away once the minimum was reached, and we kept the message also that way (6-8 letters, 3-4 digits). Not ideal, but not a big issue either. If we dont ask for zeroes in the answer key, the effectiveness of the answer key gets diluted. But this is something which we can discuss in future.

I finished all the puzzles later even though my performance was not good. Points distribution could be better. I have started enjoying puzzles lot now than earlier. This may be after solving group which helped in understanding and the idea of having focused group on single round was awesome and helpful. Thanks Priyam and Prasanna for initiative. I wish we could do same thing for each round. This is so much so I am waiting for next GP/PR round now.
The logic on Magnetic fields-Highest pointer was amazing and being author helps to decode those logic fast. Solved Anglers first time, they look numberlink to me with additional length constraint and could solve them without much trouble
Magnet 10 pointer, I could have submitted but I think answer key is very complicated, I wrongly entered in hurry and missed it, I like GP option where there is option given even to put P/N. I think we make answer keys easy and that should be worked upon.
I like skyscrapers highest pointer a lot, Priyam, I think this is your creation and it doesn't seem from 1st time author.
My other favorite puzzles [As i solved almost all offline] in no particular order

-- Skyscraper - Highest pointer
-- Hashi - 4 pointer
-- Magnet - 10 pointer
-- Anglers - 4 pointer, 8 pointer
-- All Exploratory puzzles -- I think they were just having awesome logic and wonderful creation

Thanks Priyam and Prasanna for the wonderful test.
