Does the Ripple Loop example have two solutions (see attached)? Or am I misunderstanding the rules?
Just reiterating what Feadoor already mentioned.
For every pair of adjacent circles, if the loop passes through one of them as straight, it must turn in another.
In your solution, R3C1 and R3C2 are adjacent circles and the loop is going straight in both of them, which is against the rules. |

Country : United States | ghirsch posted @ 2020-03-17 10:43 AM Oh, I see. My misunderstanding was the phrase "edge-adjacent", which I took to mean that two circles were adjacent on an edge of the path (e.g. in the example R1C1 and R3C1 share an edge of the path, and no other circles are between them).
Maybe change the wording in the instructions to simply "For any two adjacent circles, the loop must..."?

I thought the 7-pointer Trio cut and 12-pointeer Nurikabe were overrated though. On the other hand, I struggled 25 minutes to break the tricky loop closure in the centre-left center in the 10-pointer RL!

Lovely puzzle set, although I found it quite hard. That, however, is probably because I am weak at some of these shading variants, but I enjoyed it! Thanks, Swaroop! And thanks for dedicating some of the puzzles to Shaheer : ) wonderful gesture... |

Very hard for me as usual but i am just an average solver. Most were fun enough without the timer, except the ripple loop puzzles. I found even the 2 pointer to be impossible. I solved it several times and even downloaded the instructions/examples again during the test and do not understand where i am wrong. My solution is 320212 |

Thank you for the feedback. Sometimes the points can be varying based on the experience, as some of them find shading and loop puzzles easy while some find it hard, so there might be some minor variation in the Points to Difficulty experience. But I hope overall it was as close to its possible. Ripple Loop indeed was challenging. |

Country : United States | bob posted @ 2020-03-21 6:58 PM Let a = corner with loop arms going down and to the right, b = down and to the left, c = up and to the left, d = up and to the right, - = horizontal, l = vertical, . = empty.
My solution row by row is ..a--b, a-cabl, l..lll, la-cll, ll.acl, dc.d-c
This this leads to the code 320212 which is incorrect. I presume I misinterpreted the rules somewhere but I've never had so much difficulty with a 2-point puzzle.
Thanks for your time and for especially for providing something interesting to do during these crazy times. Please be careful. -bob |

May I know, which 2 point puzzle you are mentioning here? There are many puzzles. (Myopia, RL, Transparent Yajilin? ) |

Country : United States | Hey Bob. One misinterpretation you're having is that you're allowing empty spaces to occur. The puzzle instructions say that the loop must visit every cell.
The rule I was having trouble with was the horizontal/vertical adjacency stuff...mostly because I overlooked that in my first readthrough. I was originally thinking that it was path adjacent (like ghirsh) and not cell-adjacent. |

Country : United Kingdom | The instructions say 'Draw a closed loop that connects the centres of ALL cells horizontally or vertically', so your solution is wrong, namely because there are empty cells. Details like these are very important! |

In your solution, many given shaded cells are showing as unshaded. (Example R2C7). Did you solve the same puzzle?
Otherwise, it seems a valid windows solution. |

Thanks for finding my mistake. Even when re-reading my eyes gloss right over the little word "all" since I am assuming it is a Masyu variation (which it is not ). This makes the larger puzzles possible; thanks again. bob |

Great puzzles with a good balance of difficulty. I had a smooth run until I hit Windows (7 ) and Border Nurikabe (12 ).These 2 ate up a sizeable chunk of my time.In the end, I was just extremely lucky to submit the 12 pointer at exactly the last second !! Thanks Swaroop for a nice puzzle set.Favourites are Nurikabe and Myopia. |

I feel lucky for the instant grading, since my one mistake was a real mistake (I'd let some transparent yajilin clues unused by the loop) and not just an input error.

A very nice set. I was afraid of trio cuts eating my time, happily I got them fast enough. 12-pointer Border Nurikabe was pretty fun but maybe overvalued, after some initial progress I was convinced that the regions will mostly be "outlined" by borders (especially the 9 ) so it worked quicker than expected. My favorites are the large classic yajilin and the transparents. Thanks for the puzzles! Stay safe everyone. |

Country : India | Thank you, everyone, for their wonderful feedback and participation. I will divide my overall thoughts into different categories.
Puzzle Types:
I wanted to have a mix of some standard puzzles and some new variants which are bit unpopular or don’t regularly appear. So I choose Nurikabe, Windows, and Yajilin in the regulars. In the un-popular category, I was first trying to select Every Second Breakpoint and even created two puzzles of it, but was not satisfied with it, as they were coming out very trivial. Then I found Myopia Loop and really liked it, so I went with that. I also liked Transparent Yajilin and Ripple Loop very much.
Puzzle Difficulty and Quality:
Definitely I wanted the test to be on the easier side and accessible to newcomers but maintaining the puzzle quality, so that it doesn’t become trivial solve (Unless you are Ken Endo – Impressive performance). Looking at the performance with 88 solvers finishing the test, I think I achieved that. Based on the feedback from most of them, I feel happy that you enjoyed the test and really liked the puzzles.
Puzzle Points:
I think most of them agreed with the point structure, with very few of them concerning Nurikabe Borders being overrated. I partially agree with you that, this puzzle might feel overrated if you can intuitively see the areas (especially for numbers 8 and 9), then it becomes easy. But for newcomers, who are trying to solve step by step, it will definitely be more challenging. So I hope you understand our methodology of setting the points of this puzzle to be high.
Answer Keys:
I wanted it to be simple and consistent across puzzles. I know it might not be possible to do a similar thing in a lot of tests, but fortunately, it worked out here. I believe no complaints here from anyone.
Winners:
Congratulations to the top 3 Overall: EKBM, WA1729 and fff1015.
Congratulations to the top 3 India: Prasanna, Rohan, Ashish. (Special mention goes to Amit and Kishore too for finishing the test). Good performance by Priyam too, considering new in this field.
Statistics:
1) Most Submitted Puzzle – Windows 4 Points (250 Solvers)
2) Least Submitted Puzzle – Windows 7 Points (143 Solvers)
3) Most correct submissions – Myopia 2 Points (97.34%)
4) Least correct submissions – Windows 4 Points (70.4%)
5) Most Favourite types – Transparent Yajilin, Myopia, Border Nurikabe in order
It’s fascinating that most and least submitted puzzles are of the same type.
Thankings:
Thank you, everyone, again for their feedback. A special thanks to Rakesh, as always doing an extraordinary work behind the scenes, for bringing everything together, for testing, feedback, etc. Thanks to LMI for providing me the opportunity to author the round.
Final Words:
If any of you are stuck in any of the puzzles, please feel free to post in the forum, or message me directly, would be happy to help you. Best of luck for the next PR. Good luck to Priyam for Authoring Debut along with our veteran author Prasanna. |
