1-2 point puzzles need a much shorter answer key. I spent more time on Slash Pack trying to get the answer key right than I did solving the puzzles in the first place.

I join the crowd of people having trouble with the answer keys. Having to enter the numbers was very unexpected to me. But of course I didn't study the instruction booklet carefully here. But at least the description could have stated "Use digits for given numbers, '-' for an empty cell,, ...". F/B is not great but better than /\, since backslash can be really hard to enter if you're not on an English keyboard layout. On croco-puzzle we asked only diagonal/non-diagonal back in the day: https://www.croco-puzzle.com/Raetselspass/Ue-Raetsel/ue-raetsel2.php... I think that might give enough information?

Apart from that small bump, I had a lot of fun with the puzzles, thank you!

I also have the same complaint about Slash Pack answer keys, but I guess that's why there's Claim button.

I also wonder if N/Z (backslash and forward slash, see their diagonal lines) would have been better in avoiding the culture-based key.

I struggled a lot through the Araf Squared puzzles, which lost me a lot of time.

I messed up the answer keys to the Slash Pack puzzles. When I finally figured it out after going back to the instruction booklet, I didn't have enough time left to correct them all. I don't really understand the point of having to put in the numbers instead of just marking them as empty cells to be honest. It's the same thing within the rules of the puzzle as slashes can't be in numbered cells and the numbers are in set places. It could have been clarified to insert the numbers as well in the instructions as mostly clue cells are counted as empty cells in these types of puzzles that don't involve inserting numbers into cells.

Some really nice puzzles there. But again, I think this was too hard for a PR round.

The answer keys format was quite poor and cumbersome.

Solid puzzles overall, though I agree with the complaints about the answer keys. The Slash Pack keys were time consuming (e.g. there could have been just two rows/columns instead of 4) and confusing. The Fillomino keys were time consuming too. And the Rassi Silai key seems like it should depend more on the whole grid.

Again though, the puzzles were fun. My favorites were Rassi Silai (I'd never seen it before, but it was a fun variant of typical path puzzles), and the instructionless balance loop.

I would be curious to see a logical solution to the Araf Squared puzzles too, they fell reasonably quickly to intuition/guessing, but I couldn't find any good real deductions.

I really enjoyed the test especially the slash pack. I am wondering about the first Araf puzzle as I can't seem to figure out where the five in the top row goes. It is 5 or 7 away from the 7.

The Slash Pack answer keys were pretty bad, I felt it took me longer to enter 40 characters of digits, hyphens, Fs and Bs then solve the 2 point puzzle. I was constantly reminding myself which way F and B went, perhaps you can allow slashes next time? And making us fill in given digits is just annoying, as now I can't leave my fingers hovering over keys while I only look at the paper.
The Instructionless was interesting but no room in the black cells to write deduced numbers (I don't have a white pen like in the example solution!)
Anyway, the puzzles were excellent, and the Araf Squared weren't as scary as the WPC's. Thanks for a great contest. :D

i try to have the instructions on my computer screen during the test, just in case i am not sure about a certain point. keeping a printed copy handy or having it on your mobile phone could also work, depending on where, what which, etc
