Dear Admin,
Twopa: I believe behaving differently is only limited to the fact that cells that are shaded may partially differ for the same clue between two grids. OR, do I also need to consider the shape of the shaded block?? As I see in the example, the shapes are identical! that's why I am a little unsure.

Also, just curious,
Ep 1 was PR201901.
'PR2019012' follows the same nomenclature? Or was it supposed to be PR201902?

Cells that are shaded should partially differ. If you compare all eight cells surrounding a clue, at least one cell should differ in the shading between the two grids. Shape(s) may or may not be the same.


You should have been able to figure this out. Nomenclature is PR2019XX where X denotes the month in which the test starts. If there are 2 PR tests in a month, the second test has a 2 appended.

Despite not being able to finish due to issues with my printer (small downside of being on holiday), I really enjoyed this test !

The "connected" logic was nicely used, at the right level for PR imho (thas is, it was necessary to finish all grids of a group, but used only a few times so that the flow of classic solving isn't broken).

Looking forward to see this category again next year :)

TWOPA 1 i send in the last seconds, and i arrieve 4 points.
Total 35 points minus penalties
Please chek

Too complicated and frustrating for a timed test. Spent half my time on Maxi Loop 11 and 12 (which was favorite type out of the ones I tried) and checked and rechecked and rechecked and rechecked my answers. I either don't understand the rules or I don't understand the solution codes. Unsatisfying to say the least. Even after more time I still don't know what's wrong. I might be ready for a new hobby.

prezensky: Your solution was received 16 seconds after time was over. We have similar cases with many other participants too. And there are still other participants who do not submit once time is over, even if they finished just in time. So, to be fair to everyone, this submisson (1-Twopa) will not be awarded points.

Overall the test went very smoothly. But I got tripped on the "slighly" different rul of Twopa and wasted 15 mins on the first one and had to come back and solve it later.

Answer Keys were mostly perfect but the arrows pointing from the right/ bottom were confusing and I was not sure whether to enter left to right or right to left.

The size of the instructions impacted the puzzle grid size in a few cases. One possibility could have been to ask participants to refer to the instruction booklet

Hello! First-time participant here!
How do we fill out those questionnaires for feedback on the puzzles? I can't seem to find any links to them.

I felt the contest was on the harder side.Being a new round in PR, I would have preferred somewhat easier puzzles.I did my first submission at 26 mins having started with the first puzzle of the contest (Twopa) which went nowhere no matter what I did and had to drop and move on.Point distribution was certainly off for that puzzle and for Fillomino & Star Battle as well wherein I spent a considerable time.
Regarding the Twopa, my opinion is that the added shaded cell made the solve much more complex as now you have to determine which pattern fits exactly where.I would have preferred a loose start wherein you can shade some cells and shade the opposite in the other and then figure out.
I enjoyed solving Sky/Easy as ABC and Maxi loop puzzles (which were accurate in depicting the difficulty level by means of points).
Overall an okay contest where I couldn't enjoy puzzles much because of the difficulty(was depressing at the start itself).

Nice concept and excellent Puzzles.
As others have already mentioned, answer keys pointing right to left were confusing.
The difficulty was definitely on higher side compared to previous tests. The first twopa and also star battle one were definitely worth more points.
I indeed ended up making mistake in Twopa and needed 1 extra minute to finish all puzzles.
Nonetheless very fun contest.
Thanks Prasanna and LMI.

Puzzles were great!
I also had issues with the answer key arrows pointing the wrong way.

Also in the Twopas, this new shaded cell approach is a problem for answer entering. We have to guess early anyway, and solve on both grids like a normal Twopa, ignoring the shaded cell until we work out which grid it is part of. In my case my solutions ended up on the wrong side, and then I got confused (needed 5 submissions, my own fault). At least you could have made A and C the same row?

There will be a link from the score page.

Clean set of puzzles. Enjoyed it.

While the puzzle difficulty is good for a PR, just the new theme might make it a bit hard and unusual for the newcomers.

Felt the StarBattle was undervalued and the shaded cell in Twopa was just inconvenient. Some of the grids were quite small, I don't think competitors will have a problem printing more pages for larger grids.

Favourite puzzles: Maxi Loop, Minesweeper-Nanro, Fillomino-NoriNori
Thanks Prasanna!

A lot of the puzzles seemed very suscepible to guessing, e.g. fillomino-starbattle or some parts of the skyscrapers, because you could finish 95% of the first puzzle, and then guess instead of relying on the second puzzle to disambiguate between two final bits of the solution. Not sure how I feel about this.
