I always dread this round most in the PR series (mostly something I should work on improving), but this was super fun, and also had a very neat theme. I loved how the thematic sets represented the correct difficulty too for the most part.

I got in my own head with the HARD Curve Data. I should have done it much sooner and omitted a key possibility visually which I shouldn't have. I came back to it with a fresh mind at the end and immediately saw it. Really dumb of me. Also, I have a phobia of Masterminds and so avoided them till the end but I probably shouldn't have as these were way more clearly logical than most Masterminds I have done in the past (or I may just have spotted it quicker) and I zipped through them right after the contest. Probably if the Curve Data mess up hadn't upset my rhythm I could have finished this set.

Other than all that personal drama, this was an excellent contest. My favorites were probably the Cross Words section. Thanks Amit!

Too hard but what an incredible set of puzzles. Most of the themes were fantastic and the answer key of that Word Nurikabe was a cute little touch.
It also looks like no one would have completed this set without Instant Grading (based on the first 13 players to complete it at the time of posting this).

Favourites: Hard Matchsticks, Medium Curve Data, Hard Curve Data.

Clearly I spent more time admiring the puzzles than checking my answer keys :D

Can't remember the last time I gasped 'Oh Wow' during the solve of a test.
Thanks Amit for the fun and hard puzzles as always!

Thanks Prasanna, for most of the puzzles I used the grid size to adjust the difficulty. The larger grid sizes also allow to introduce more subtle logic for solving.

Thanks Rohan.

Agreed on the instant grading. Till now there is'nt any full score without mistakes.

We tried to adjust the puzzle difficulty for the test. Word Nurikabe was introduced later to lend some balance.

Will post the slightly harder puzzles after the test.

Fantastic test! Even though i did not come close to finishing, the feeling of having attempted a good number of puzzles brings some satisfaction. The logic in the puzzles were very clean and thorough. Favourites were Word Division 2, Mastermind 2 and 3.
Not being able to complete the Word Nurikabe 6 ptr and the 9 ptr Letter scrabble was a disappointment. Look forward to finishing the set later.

Thanks Amit, Great puzzles!

Hi Grizix I respect you opinion on the puzzle quality and point distribution.
However I felt the answer keys for any online test cannot get simpler than they were for this round.
Do you have any specific suggestions on improving the answer keys?

That was a beautiful and high quality set of puzzles. It was frustrating at the end to have completed the Word division (11 pointer) but then having the timer run out before answer key entry.

I lost faaaaaaaaaaaaar too much time on the Letter Scrabble having put HARD in place of HERD and HERD in place of HARD and the ERA in R3C1-3. I checked and double checked to find where my error existed ?!.It took me a despair and agony filled 10 minutes to realize that the words are not connected in the above pattern.So swapped HERD and HARD and put the ERA in between.Lost a lot of time in the above process.Could have hit 70 barring this skirmish.

Very interesting set of puzzles.Would love to finish the rest later. Thanks a lot Amit!

Overall a very nice test. The theming is excellent (although it's questionable that the curve data has "easy" worth 5 points and "medium" worth 4 points...) and the puzzles themselves were mostly nice.

Matchsticks is a very weird genre, and I'm not sure it's logical. I'm sure most of the penalties by people are in this genre. One good thing about commonly encountered puzzles (Nikoli-style etc) is that you can verify your answer easily; here, verifying your answer to Matchsticks requires you to practically solve the whole thing again. (All optimization puzzles fall in this bucket too.) Not that it's a bad idea to include them, but you need to be really careful with how you do it. I'd say Matchsticks 2 is the most difficult puzzle in the test; Matchsticks 3 is in fact fairly easy (you have enough room to make practically any number you want, so getting a proof is really quick).

Some minor quibbles: Easy as Snake doesn't need the word separation (spaces are irrelevant for the puzzle), but it's fine. For Word Division, with how many native English words are used, I largely intuited the solves by trying to read some reasonable words I can see from the board; people not used to English won't be able to do this.

Double Cross turned out to be particularly enjoyable, compared to my first reaction of "huh, won't this be really trivial?"

With Matchsticks, sometimes you can get a lower number by moving less than N matchsticks. I assume this is ok?

For example: N=2, start="70". With 1 move I can get to 18, but if 2 matches have to be in new places then the answer will be higher.

Exactly N matchsticks need to be moved. Solution obtained by moving "Less than N matchsticks" will be invalid. I hope this clarifies.


Well that wasn't true.
The solution to #3 requires moving 4 matchsticks, not 7, and is therefore invalid according to your statement!

I spotted the 'obvious' answer (smallest number using 23 matchsticks) immediately, then spent a long time looking for larger numbers that needed more moves.
At least with instant grading I eventually gave up and put it in just in case I could move on.

There is a solution that gives the same number that moves exactly 7 matchsticks. It leaves a gap between some digits.

Thanks Amit for this enjoyable set! Word puzzles were very nice. In casuals, I did a blunder in mastermind 3 and lost a lot of time. My favorites puzzles were: word nurikabe and curve data.

You could reach the answer with 7 moves (or any n really) if some moves were transpositions. (Ie. Keep moving the D around until you have 4 moves left). I agree that it's a questionable inclusion.
A possible improvement would be making sure that the solution is reached by the minimum number of moves.

Thank you so much for this wonderful set, Amit!
I was dreading the casual and word round since the week where that I missed the object placement round, and realised that this round will be crucial to getting that 4/6 round base points. I was aiming to score about 30, so I am quite happy with the number of puzzles I could logically solve!

Absolutely loved the Easy, Medium Hard themeing, the cute easter egg answer key on the last puzzle, and the word puzzles were all very logical and enjoyable!

I think I spent a LOT of time trying to figure out puzzle 6 (mastermind), and I don't think I understand i even now :P, but other than that it was smooth sailing for me.
Loved the round!
