Hi,

I am new to Penpa and was looking for a way to enter a number and draw an edge without having to switch between the two repeatedly, mainly for Filomino.

Is there a way to do that?

Thanks,
Nikhil

Currently there is no hybrid mode. But I hope you are aware of Tab feature. Pressing Tab allows you to quickly switch between Number and Edge.

Wow, pretty difficult round! The Fillominos in particular seemed quite tricky (especially Fillo 1; I didn't expect to need a maximality argument for a 4 point puzzle). Solid puzzles though; I'll get around to the ones I didn't do someday :)

Will solutions eventually be posted? I have a blind spot somewhere and just cannot solve the right hand side of Fillomino 3 (the 12x12) Obviously after the test is over :)

Thank you, it was a very fun set of puzzles! I'm glad I continued on to solve the ones I didn't get to during the test, Compass #3 was a standout for me.

Thanks Swaroop for the delightful puzzles. My performance was below par. I got stuck with Fillo-1 & 2 at the beginning and got too late to pull back.
Nevertheless, the puzzles were thoroughly enjoyable. My favorites were Double Choco-3 and CombiBlock-3.

Thanks Harmeet. Unfortunate that you got stuck.
I hope you solve all the remaining puzzles at your leisure and enjoy them as well.

Had fun solving these puzzles. The practice links and videos provided were very helpful. I practiced a lot and was pretty confident with filomino, shasigane, spiral galaxies and combi blocks and had decided to attempt these ones first. but as it turned out, I got stuck in the filominoes at the very start and wasted a lot of time there. Headed straight to shasigane and spiral galaxies and got them out of the way and then their Max versions. didn't expect to get stuck in combi block but I had very little time left when I got to it and so made a mistake in hurry. Could not get to the compass puzzles at all.

First time, I tried solving on Penpa. Was fun.

Fantastic set of puzzles but extremely hard for PR. Could have been more enjoyable otherwise.

No particular favourites since most were high quality but generally liked the Combi-Block and Double Choco sets.

Thanks Swaroop!

High quality puzzles but found them way too hard. Heavy dislike for the contest. No fun at all. More easier puzzles would have made the experience better.
Also one feedback regarding formatting. Dotted lines and (dots as well) got wiped off when I erased to fix a broken part in Combi Block (7 pointer)and that left me stranded for the last 20 mins...

Nice and hard puzzles. I practiced most of the types before starting this test and was very (over) confident to complete this test. However, my confidence was shattered with the first Fillomino puzzle itself.
Loved each of the puzzles in this test. Thanks, Swaroop for these great puzzles.

Very nice puzzles! Got spooked a bit by the opening fillominos :) But everything went more or less smoothly except compasses. Glad I got them eventually but I really need to improve at the genre.
Favorites: Double Choco 2, Sashigane 1, Compass 1, Spiral Galaxies 3.
Thank you!

Congratulations to all the winners.

Brief background of the contest:
We selected only those types which were available on puzz.link with a thought that it will allow solvers to practice these genres.
I also wanted to challenge myself and so I picked all the new genres except Fillomino. New in the sense, I created these genres for the first time. One thing I realized while setting these genres was, they are so uniqueness prone. I created multiple versions of puzzles which would break at the end because of non-unique. Eventually the struggle came through and I was happy with the logic behind all the puzzles.

Statistics:
Most submitted puzzle: Spiral Galaxies 2 (205)
Most correctly submitted puzzle: Spiral Galaxies 2 (99.51%)
Least submitted puzzle: Compass 3 (76) - Expected
Least correctly submitted puzzle: Max Spiral Galaxies 1 (73.54%) - Shocking

TakeAway:
Firstly Sincere apologies for the minor mistake in the Spiral Galaxies at the start of the contest, which may have affected 4 to 5 solvers. Apart from that, Most of you liked the puzzle quality and enjoyed solving the puzzles. I understand the difficulty became harder than usual PR rounds. I guess being new genres, I couldn't accurately gauge the difficulty and there was less time to do multiple iterations but will surely keep this in mind for next time.

FinalNote:
I hope you solve all the remaining unsolved puzzles in your liesure and maybe also the puzzles you may have guessed through during the contest and would like to discover a nice logical solving path. If you get stuck, feel free to post here and would be happy to guide the next step.
All though I am really happy with the way the puzzles turned out, my personal favourite was the entire Compass Set.
Thanks to everyone for providing their feedback here as well as in the Discord servers.

I now pass the Ball to Priyam for the next PR round (Object Placement). Best of Luck! Eagerly looking forward for the test.
