Posts: 1 Country : United States | alien2357 posted @ 2010-08-15 12:41 AM Great set of puzzles. Awfully difficult. I'm glad I was able to participate this time around. Can't always have 2 hours straight to do puzzles, but when I do, it's always FUN! Everyone at LogicMastersIndia should be commended. Your mock tests and other puzzle sets are typically high quality stuff. Thanks! -Allen |

I struggled on the higher point ones, maybe there is something that Im missing in solving the more difficult ones. Matchmaker was awesome. It was not too difficult to identify which sudoku goes where. The puzzles were high quality too, especially the anti knight sudoku. I broke the touchy sudoku, else would have had a few more points :( It might have been better if there were more time to solve, or maybe two separate sections, so that people do not have to choose between which section to solve. |

I'll be surprised if more than 2 people can achieve this goal. P.S.: I like surprises ![]() |

Posts: 42 ![]() ![]() Country : Serbia | skywalker posted @ 2010-08-15 4:45 PM I had no problem to identify puzzles in matchmaker (7-8 minutes for all eight), but some of them were really hard to solve and I lost a lot of time on them. Classics were as always from Chinese authors, beautiful & tough. I enjoyed after the test solving puzzles not solved during the test. Thanks for great puzzles Branko |

Posts: 42 ![]() ![]() Country : Serbia | skywalker posted @ 2010-08-15 10:07 PM I had only doubts about diagonal and 3 in a row (E/O) after about 5 minutes, but with small guess i resolved that. I was not well prepared for this competition, I haven't seen points table before the contest and I spent most of the time solving some difficult MatchMakers puzzles and not solving classic relay. But, anyway, excellent and enjoyable test. Branko |

I at least learned this time that I don't need to type in the whole answers but with so much typing at the end I forgot to hit submit on my nonconsecutive :(. Off to finish the last puzzle. |

Posts: 40 ![]() ![]() Country : China | Minfang Lin posted @ 2010-08-17 5:31 AM Thank you for every participant and your feedback, it help us to do better in the future. We will show you some design idea in Qixi: First, the classic relay part, please have a look at every puzzle's clues, they're from 20 to 27. but when solve them, you will find they become more and more difficult. In many people's concept, more clues mean much easier. In fact, count of clues and difficulty are not equal. We don't tell you the correct position of every stick digit, but you can determine them by logic. There are many players become puzzle designer, and the process of determine stick digit is also a design, no matter if you had tried design a sudoku, in this test, you had tried. Fulfill the puzzle, then solve it. That's why many players like the classic part. And we also do some thing about this: if you put digits to the wrong place, you will find no solution for the puzzle, or if you haven't decide all marked cells, you will find multiple solution. To the puzzles themselves(i mean when you put all stick digits in right place), when solve P01 from 1 to 9, you can get all 1, then all 2...all 9, maybe you never find solving sudoku is so happy. P02 - P06 are puzzles can be solved only by singles, but we make them difficulty in observing. P07 - P08 need intersection, pairs and x-wing, they are all basic advance techniques. To variants match part, at first you will find that you can't solve any number by clues, it's like mock test 11 last year. Then you must determine every situation's rule first, it's mostly like a sudoku, and hints are from eight situation. We make a diagram for you: ![]() (They are all from clues, no guessing or trying to solve one situation for finding a mistake.) There is a trap in P09, you can try to solve it by diagnol, it has unique solution, but it's a very tough puzzle and you will find another situation don't have rule to correspond. P13 and P15 have the same pattern, it's only for fun :-) By previous 16 puzzles effort, a "heart" bridge is built. In this twins suoku, you can only solve few cells in single grid, but when make them together(same meaning of "17" in Chinese), can be solved by single. It also means one need to support others. At the end, thanks for LogicMastersIndia give us the chance, and all you spend the wonderful Qixi time together. TTHsieh&Leafcard |

Posts: 774 ![]() ![]() ![]() ![]() ![]() ![]() Country : India | rakesh_rai posted @ 2010-08-17 8:05 AM Congratulations to the top 20. 600+ in this test is indeed a great score. I thought that Diagonal should be the easiest variant (as it is the most common variant) but after looking at the results, it (along with Touchy) proved to be the toughest of the lot. Was the 2-hr timing enough? The scores suggest it was not. |

Looking at scores and when I see that no one including Snyder or Janoslaw could complete it, its evident that 2 hrs was not enough |

I'm sure they have lot of time designing the Sudokus (e.g. in all MatchMaker puzzles it was not possible to solve a single digit without determining its type) [ That probably made it tough :-) and Niulang and Zhinv could not meet ) 2:30 hours test would have ensured that at least a couple, if not many, players would have got the bonus points. Thank you again. |
