Both passwords are displayed in the submission page after you start the test. |

We have uploaded an updated pdf. So all participants who are yet to participate please download the updated version. 2) The Nurikabe 10X10 puzzle is incorrect. 3) The Numberlinks puzzle has multiple solutions. 4) The Heyawake marathon puzzle is incorrect. Password for marathon pdf is different than main puzzle pdf. Both passwords will be displayed after you start the test |

Posts: 7 Country : Bulgaria | Deyan posted @ 2010-10-09 11:15 PM I had the bad luck to solve the wrong PDF. This is what I found: #1 Numberlink - multiple solutions When I realized it, I just found a solution that is using all cells and got points #5 Akari - 4 solutions For luck, all solutions have the same answer, so no problems with it #12 Nurikabe - wrong image I spent a lot of time on it. After time limit I solved the bigger Nurikabe for about 1/3 of the time I spent on this. Actually, it's very easily fixable: just change '4' to '3' at R5C10 #16 LITS I also spent some time until found it's wrong (one small line, but a big difference) |

Posts: 11 Country : Bulgaria | StGeorge posted @ 2010-10-10 4:36 AM The heyawake marathon was wrong? I didn't notice. It did take me quite a while to solve it - about 75 minutes - but I didn't see any mistakes. I'm sure I can easily be missing something and the correct version that Tom posted looks quite a bit different. Can someone tell me what the mistake is? Or is it that the one in the booklet is still a valid heyawake, just not the one that was intended? That would be a weird happenstance :) |

Posts: 152 Country : United Kingdom | detuned posted @ 2010-10-10 5:37 AM I didn't notice either - until it was too late. There was a thing quite early on in the solve where you have a choice between either entirely surrounding an empty square with shaded squares, or else leaving 3 rooms empty in a row. The latter option was apparently quite subtle as I must have passed over it at least four or five times. Either that, or I'm an idiot. The new version is basically a fiddle to change as little of the solving experience (after wrongly assuming the 3 empty rooms in a row) as possible - I'd estimate about 80% of the puzzle solves the same.

Posts: 199 Country : United States | motris posted @ 2010-10-10 10:24 AM I obviously had the benefit of the "improved" test, but that won't keep me from my typical counting error (on the highest possible valued puzzle to boot). Got through all the solvable puzzles though. I think the marathon Kakuro was guilty of being too cute (not a good thing in a competition), but otherwise a lot of very fun puzzles to solve. Thanks for the puzzles Tom. Edited by motris 2010-10-10 10:25 AM |

Posts: 172 Country : ITALY | forcolin posted @ 2010-10-10 2:54 PM I made it too although my PC froze as soon as I copy/pasted the pw. Had to reset and reboot and lost 5-6 minutes. Therefore I guess this time motris will beat me Nice set of puzzles, although I did not always find a straight relationship between the points awarded and the difficulty level. Thanks Tom, better luck for the future stefano ps: how do I rate the puzzles? Edited by forcolin 2010-10-10 2:55 PM |

Or is that puzzle out of the competition like the incorrect ones? |

Country : India | debmohanty posted @ 2010-10-11 6:40 AM Results are published - http://logicmastersindia.com/M201010P1/score.asp We've followed a simple method Nurikabe = 0 points for all NumberLinks = 20 if player solved with old pdf and answer startsed with 1114, 0 if player solved with new pdf This may not be the fairest way, but I guess there is no fair way to compute how much time a player spent on broken puzzle to compensate them for that. We've disabled the ranks this time - you can sort by Points though. Thank you everyone for participating. And we (debmohanty, amitsowani, detuned) apologize again for the mistakes which could have been avoided. |

Country : India | debmohanty posted @ 2010-10-11 8:21 AM There were 184 participants - 151 of whom got non-zero scores. Here are some stats : of countries - 35. Top 3 (Based on #of non-zero entries) Ind - 21 Japan - 18 USA - 16 Beginning of last week there were many new users registering from Japan that at one point I was thinking there will be more participants than Japan than India. But Japan has highest Avg Score "754", and it won't be difficult to imagine how famous Nikoli is there. |

Country : India | debmohanty posted @ 2010-10-11 1:26 PM Please provide feedback about the puzzles. If anyone needs hints / steps to solve any puzzles, please don't hesitate to post here. From the score page, it looks LITS is the least solved puzzle (okay, after the new pdf is uploaded) No prizes for guessing the most solved puzzle - yes it is Sudoku! P18 - Slitherlink was most incorrectly entered puzzle. |

Country : India | debmohanty posted @ 2010-10-11 5:26 PM @Keshav : I assume you are talking about P06 Masyu, because that is marked as 0 for you. We are absolutely certain that the P06 Masyu is correct and has only one solution. You can upload your other solution (in image format) in this forum. |
