Posts: 170 Country : Germany | rob posted @ 2019-01-25 7:59 PM Great concept, and pretty good test, thanks Prasanna! I tripped up a bit on the first Twopa, thinking I couldn't get out under the 13s in both puzzles. I feel like they were quite tricky anyway, an easier starting type would have felt more friendly. The Fillomino relay types are really fun ideas. Some of the types were a bit low on interaction, with the connection rule mostly coming in towards the end of the solve. But keeping them easy seems appropriate for the PR. * The Twopa disambiguation via shaded cells late in the solve were a bit of a pain. If you want to do it like this, at least ask for the same rows/columns in both grids, so it's easy to read off if you've solved the other way around? Or ideally just accept both combinations. * The code order and direction on the right grids in the 4-by-4 types is confusing. Intuitively, I'd want to fill the "top" codes before the "right" codes, and read the "right" codes right-to-left. Improvement (but not perfect): point the arrows on the right and below the grid right and down, respectively. | ||||||||||||||||||

If you want to do it like this, at least ask for the same rows/columns in both grids, so it's easy to read off if you've solved the other way around? Or ideally just accept both combinations. Valid point. If a solver ended up solving the other way around, answer keys for 1 go into 2, and answer keys for 2 go into 1. Of course, you would have to select the correct rows/columns. But that should not be a big constraint (we thought so). We had a discussion on this exact point before the contest and then decided to go ahead with the current approach. If it was an offline contest, there would be no issue but this adjustment was only because the contest is "online." * The code order and direction on the right grids in the 4-by-4 types is confusing. Intuitively, I'd want to fill the "top" codes before the "right" codes, and read the "right" codes right-to-left. Improvement (but not perfect): point the arrows on the right and below the grid right and down, respectively. If someone enters top code before right code (that is intuitive), it will still be marked correct (although it is not mentioned anywhere). We have emphasized left-to-right and top-to-bottom wherever possible. And the IB examples also illustrate that. We just wanted to stick to the "rows before columns" mentioned under the generic section ("If one row and one column is marked, enter the row first and then the column"). Your idea about the arrows' direction is also a good one, perhaps better than the current depiction. We did not want the arrow to point outside the grid, as that may have also introduced some confusion. Thanks for the useful suggestions! | ||||||||||||||||||

Regarding answer keys I think backward arrows are confusing. I would also prefer if Twopa did not have shaded squares to force each solution to go in a specific grid, since that gives a potentially undesired break-in, and it makes it hard to plan answer drawing. I don't know if the scoring setup allows for multiple possible answers though. I also don't like that the answer keys were separate for each grid, since if you guess to finish one piece of the puzzle I don't think you should be able to confirm that it's right until you finish the other grids. Otherwise, I loved this contest though! I think connected puzzles are always really fun, and it's cool to see a full contest of them. EDIT: Looks like rob already said a lot of the same things.

Posts: 4 Country : United States | boing posted @ 2019-01-26 12:32 AM ghirsch - 2019-01-26 11:13 AM Regarding answer keys I think backward arrows are confusing. Very! In some of the puzzles the answer key instructions made it clear that the reading order was still left-to-right and top-to-bottom but not in all, and I happened to start with Norinori which did not include those instructions so I lost points because of this. I hope admins will consider retroactively awarding points for backwards answers on those - I'm sure I'm not the only one!

Mostly the same comments as ghirsch. I got tripped up by the left arrow in the norinori (like boing) and found the twopas confusing because of the one shaded cell. In the twopa rules: "This means, in a multi-digit clue, some of the digits can have the same behavior, but not all," I would have liked the example puzzle to clarify whether a single-digit clue could have identical behaviour between two grids (I guessed not but couldn't solve the puzzle). With partial marks I noticed one of my mistakes by submitting an incorrect subpart which you wouldn't usually be able to notice, so I felt like having separate answer keys was bad - perhaps you could still submit separate answer keys but only mark them individually at the end of the contest / when all other subgrids have also been submitted. A very nice test though - the logic was nicer than I was expecting in the puzzles I did solve (especially the linked skyscrapers-easy as 123). | ||||||||||||||||||

I also got tripped up by some backwards arrows, and I couldn't finish the harder Linked Maxi Loop! Still, nice puzzles overall. Personally, I think the Fillomino/Star Battle relay was worth (a lot) more than 2+2 points. Edited by mstang 2019-01-26 10:48 AM | ||||||||||||||||||

Posts: 74 Country : United States | mstang posted @ 2019-01-26 10:45 AM @2 above: Yes, the rules for Twopa as I would state them are: "for any pair of corresponding clues in the two grids, the arrangements of shaded/unshaded cells in the (usually 8) neighboring squares cannot be exactly the same." So that applies to single-digit clues equally well. Edited by mstang 2019-01-26 10:47 AM | ||||||||||||||||||

Very interesting, novel theme. Many interesting uses of connected puzzles. I'm not sure if it fits for PR, but seeing the many easy puzzles I think it works well enough. Some problems: - Connected puzzles should be considered as a single puzzle. Answer keys should span over the many grids, otherwise solvers can check partial work by submitting the answer for a grid, and if it's correct work from it for the other grids. Unless this is intentional. - Some grids are (mostly) solvable without using the connected gimmick. Again, this might be intentional due to this being PR, but I see that as a downside. But overall trying a new mechanic like this is interesting and I'd like to see more. Maybe variants like "liar" or something as a theme? Edit: Apparently this echoes a lot of similar comments. Well.

For some reason I kept making mistakes, especially on the large Maxi Loops, which I printed out again. Still happy to have finished the round. There were some great puzzles here, and I generally enjoy linked or relay puzzles. I hope this becomes a regular round in PR. Thanks Prasanna for the very enjoyable set! | ||||||||||||||||||

Instead of guessing you could have read the rules where it mentions "every clue must behave at least a little bit differently." and a single digit is also a clue.

I have also been confused by the right-to-left arrows with the left-to-right key. Nevertheless, these puzzles really gave me some kind of flow. Good job! | ||||||||||||||||||
