Posts: 102 Location: United States | Regarding the booklet formatting, I somewhat prefer the bank in domino puzzles to be formatted as below (or flipped) rather than the way they were in this test. The disadvantage is that it takes up more space, but for me it makes it much easier to think about which dominoes I have already found and which I have left. I don't know what other people's opinions about this are though, so maybe this is just me. Edited by ghirsch 2015-11-01 11:29 AM | ||||||||||||||||||

(I could place only 3 magnets in the entire grid after lot of struggle) ? The fourth magnets puzzle uses minmax constraints. Look at columns 3,4 and 5. A column with few signs filled (2,2) is surrounded by two heavily filled columns (4,4) and (4,3). This should give you a start Thanks amit. But I guess you are explaining it for Magnets 8 pointer (3rd puzzle). That I already got. I am asking for last one (4th Puzzle - 9 pointer) ? The fourth one is based on transfer of polarities across rows (transfer = number of unbalanced vertical magnets across the two rows). Look at the number of vertical magnets required across rows 4 and 5, 5 and 6. Also look at columns 6 and 7. | ||||||||||||||||||

Thanks Amit for a challenging set of puzzles. Definitely harder than normal. (And this set was difficult to solve without paper.) Most puzzles would need some tricks and techniques - a good test from a learning perspective. | ||||||||||||||||||

Got through most fairly quickly, but got completely stumped by the hard Hashi's and Magnets and ended up scoring no points in the last 15 minutes. Given the relative short test, and relative to the difficulty levels of the others, I thought those were a bit too hard. My favorite puzzle was Multiple Anglers: very nice! | ||||||||||||||||||

Great test, thank you! It turns out I have some things to learn about Arrows, and also some things to practice -- I missed so many of the "obvious" deductions at first. Edit: I think I should retract my judgement on the point distribution. I just went through my results, and things seem pretty even: * hashi: 1.6 points/minute * magnets: 1.4 * arrows: 0.6 * anglers: 1.6 * dominos: 1.8 The low arrows score is due to a bad performance, not due to difficulty. I did think I got through the magnets very cleanly and found the somewhat tricky deductions immediately, so that one might be a little undervalued. The dominos felt quite easy, but were low-valued accordingly. Edited by rob 2015-11-01 11:03 PM | ||||||||||||||||||

Hex Slitherlink Author Posts: 145 Location: France | Hmph. Assuming that one will be able to finish a PR round within 90 minutes is the wrong strategy. I never figured out how to do Arrows #3 and by the time I decided to move on it was too late to catch up. | ||||||||||||||||||

Arrows #3: I spent over 15 minutes on it and never found the solution or even a reasonable solve path. Hashi #2 and #3 (4 and 5 points) took much longer than any of the Magnets puzzles (8 and 9 points). I am not sure if the point values are aimed at beginners or at seasoned players; if the latter, then they are problematic (Magnets is easier than you seem to think it is), if the former then the overall difficulty of the round is problematic. That said, it was still fun. Apart from Arrows #3. | ||||||||||||||||||

Posts: 102 Location: United States | auroux - 2015-11-01 12:35 PM Arrows #3: I spent over 15 minutes on it and never found the solution or even a reasonable solve path. If you're still looking for how to start it, I think the break-in is meant to be the 3 in the middle. There are only four possible arrows that can point to it (no diagonals), and you can quickly find that two horizontal arrows doesn't work, so you need to do two vertical arrows. From there I don't remember running into many difficulties. | ||||||||||||||||||

Posts: 187 Location: New Zealand | I have learnt that I find it surprisingly difficult to (correctly) count the number of line corners in a row or column... :) Thanks Amit! | ||||||||||||||||||

I liked the (new to me) 5s interaction logic in the Hashis. I thought Magnets 3 was hard/undervalued. | ||||||||||||||||||

Hex Slitherlink Author Posts: 145 Location: France | Thanks -- yesterday I just didn't see that 3 in the middle. I was obsessing over the 4's on the diagonals for exactly the same reason, but somehow didn't think of the 3 even though it's obviously a better place to start. Okay then, I have to take back some of my negative comments about the puzzle difficulties. I was just being stupid. (I still found Hashi and Arrows to be huge time sinks compared to other puzzle types for equal point values, but possibly it's because I'm just not good at those. My answering timeline doesn't quite reflect solve times due to my computer crashing partway through and needing to be rebooted twice). | ||||||||||||||||||
