Thanks Prasanna, this one is a lovely test.

Sometimes I act so stupid, like I've acted here. I spent 10-12 minutes for the 2nd Rassi Silai puzzle because of the grey region. I thought that all nine regions should have own path, and of course I tried to make it happened. However, I couldn't accompish the my weird goal :D In 2012, in Croatia, there was a part and that part contains Battleship and Snake puzzles. I'm reall good at Snake puzzles, so I gave a shot, but after several minutes I couldn't solve, and I was sure that there was not any solution of that puzzle. It was obvious, it's impossible to place a snake into the grid. Then, I saw my stupidty, this was not a Snake puzzle, this one's a Battleship puzzle which were given only two one-unit ships of the fleet. I assumed those were the Snake's end points :D So, I did similar things in here, and lost so much times, because the grey region had to be empty :D

Thanks Prasanna, again!

Thanks for a beautiful set of puzzles! Hard to pick a favourite among them, but Araf squared was fantastic (and I normally dislike araf - or so I thought - so that's saying something...).

My only complaint is that some answer keys were a bit too long, four rows/columns for Fillomino seems too much to me. Also, the answer key for Slash Pack was super weird. (I guess it may have actually taken me longer to enter the answer code than to solve the puzzle...) Is there any reason for the choiche of f and b? I had to check the instructions every time because I couldn't remember which was which.

f = forward slash, b = back slash

Again, the feedback form leaves a lot to be desired. I don't think too many hard puzzles is a bad thing, and I don't know if you are measuring distribution by #of puzzles or #of points - but I think in either case hard puzzles accounts for much more than this supposed 10% target.

I also find it hard to believe that anyone gave an honest second opinion about those answer keys! Some were certainly not proportional to the points available for a particular puzzle.

Other than that, quite a nice test. Thanks!

Might this be pushing the boundaries of "culture neutral" a little too far? Was any consideration given to using / and \ instead?

You entered '-' instead of numbers. However, we will review your (and everyone else's) submissions for slash pack, as that is an error in entering a "given"

I normally really enjoy the PR sets but found this one VERY frustrating. Point distribution seemed off. Especially with unfamiliar puzzle types, I use point values to identify easier puzzles to start with. Here, it seemed the opposite. I thought the 2-point rassi silai was the hardest one. The 1-point place by product took a lot of trial and error for me. Could be my own experience though.
The answer keys for slash pack were extremely frustrating. I painstakingly wrote b's and f's on my diagonal walls and carefully typed them. All were wrong. Tried capital and small letters, turned my paper, quadruple checked solutions and rules. I still don't understand what I am doing wrong and wasted a lot of time. Ugh.
Aside from these issues I liked seeing new types. I really liked the rassi silai and (ragular) araf.

Yes. But that causes a glitch in the scores. We can mention next time such a case arises that we will accept the answer if b and f are switched too as long as they are consistent.
