Country : France | auroux posted @ 2017-02-15 8:50 AM Hmm, I know it's too late to change things now, but I'm not so happy about the design of the answer keys. Why make the answer key different for Bosnian road vs. Bosnian snake? Clearly in Heyawacky you wouldn't need to ask for the lengths of the "groups" of black cells (always 1) if you didn't want to have a uniform answer key system for all shading puzzles, so why throw that away for Bosnian road? (The answer key isn't consistent with the other loop puzzles either since those only ask for the longest segment, not for all segments). I feel that we're just going to get very confused.Denis

This is a valid point. The answer key for Bosnian Road will be made consistent with other loop puzzles and this will be updated in the IB and PB. |

Very nice test. Heyawacky 3 is my favorite for the amazing break-in. I need to figure out a logical solution for Yin-Yang 3. But in general, all puzzles are of high quality, with pleasing aesthetics (Yin Yang 2, Lakes 1, Bosnian Road 3, Lakes Loop 2 ) and nice solving paths. |

This was a beautiful set of puzzles. I got a bit lucky with guessing but the solving paths are just fantastic.
Perfect balance of puzzle difficulty and types. I think this is easily my favourite PR round across the two years. Great job and thanks a lot Walker! Looking forward to more of your puzzles in the coming years !!! |

"NOT touching" means not touching at a point. If this restriction is not there,then the loop can possibly touch at a point in a cell. |

Fun test, as are all of the Puzzle Ramayan series. It is satisfying to finish more puzzles within the time limit. I also enjoy the intructionless puzzles (none on this set ). Looking forward to the next one. |

Country : India | In Heyawacky, does "the white area cannot span across 2 consecutive borders (thick lines)" mean a horizontal or vertical segment of white cells cannot be in more than 2 regions?

Apart from the first one, Almost Simple Loop felt more like Outside Yajilin. I thought Bosnian Snake was a bit of an odd choice as a shading puzzle, particularly with Bosnian Road in the second part. Speaking of Bosnian Road, it would have been nice to avoid the differing notions of loop length for the answer code.
Assuming Lake Loop is original (I don't remember seeing it), that one might have been a fun instructionless puzzle, too, though I guess it not being a variant of another of the loop puzzles is an argument against.

Excellent set of puzzles. Exactly suitable for PR environment. Thanks to author and LMI for conducting this test. Apart from 10min waste of time at start due to printer issue, everthing else went smooth. I really enjoyed the test. I am happy I completed the set, after missing the completion of 1st PR round closely. YinYang 3 was the one which took most of my time. Rest all were smooth solve. Heyawake was nice logic. Fortunately i created some Heyawake with similar logic so found it quickly. |

I think Lakes Loop is the same as Nurikabe Loop (Akil Oyunlari Magazine Competition), no?
Most of these were intuitive types - so I think guessing is probably more efficient than finding logical paths. |

Thanks for the fun puzzles Walker! I spent way too long on Heyawake 3, but once I found the break-in I was very impressed, and it ended up being the most memorable one from the test. |

Great test, thank you Walker! The biggest Heyawacky is the best one I've ever seen : ) Anyway, I should have done better, but my printer has decided to print only 4 out of 8 pages : ( |

Country : India | Thanks to Walker for authoring this test. Also thanks to Bram for test solving.
Congratulations to Endo, Rob and Hideaki for finishing the test with a combined time of less than 90 minutes. Endo's score is the best ever in any SM or PR episode so far.
Congratulations to Rohan, Swaroop, Rajesh, Ashish and Kishore for taking the top India positions.
Heyawake 3 was attempted by the least number of participants, but it was the most accurate submission too (82/83 correct answers). It had a nice solving path/trick. Those who have not attempted it yet should try it at leisure. |

There was a slight issue with the differing entry style for the solutions of the Bosnian road compared to the other loop puzzles. I spotted it beforehand but it could have been easier if they all had length of line or number of squares, rather than a mixture. |

The Almost Simple Loop feeling like Outside Yajilin was intended - we wanted to transition from the Simple Loop in last year's PR to something that is like another loop type, but still keeps the link to last year clear.
Last year, when we had a Snake round, some people noted that Snake is also a sub-genre of shading with a mixing in of path constraints. This year we have Pentomino instead of Snake as the specialized round, so it was good to have one snake somewhere and this seemed like a good spot : ) Both variants are meant to take something from the other part, Lakes Loop was a step up from Lakes in the Shading side and Bosnian Road was a step up from Bosnian Snake in the Loop side.
Lakes Loop is indeed Nurikabe loop as Tawan pointed out. Since it doesn't have the 2x2 constraint we thought it was ok to name it Lakes loop here, especially to maintain the link to the Lakes type instead of making it feel like bringing in an entirely new type.
These weren't planned beforehand, but after some of Walker's initial submissions it just developed into these ideas. |
