Posts: 337 Country : Switzerland | Fred76 posted @ 2012-03-09 3:05 AM As there is a big majority in the poll who said that it were not better to have marked diagonal in the anti-diagonal sudoku (or it does not matter) , I'll not add them. Sorry for the 7 people who voted for marked diagonals in the anti-diagonal sudoku, I hope you'll have fun solving this grid despite that. Fred |

I got through this one by a complex work through of where the 9s can and can't be, first of all I'd suggest you put the 8 in R1C1, as the 5-7 pair take up the below row and the 9 in the middle omits a 9 in either of the main diagonals. After that, either just look at the 9s and think hard about the possibilities with the queen rule, or find another way and tell me as well |

Prasanna is right, you must study the 9's and try to find a contradiction. I think it's the only possibility to crack this grid. For example, if you try to put a 9 in R6C1, then you have a 9 in R9C3 (only option is that box), then it has to be in R8C9 (only option in this row), then in R4C7 and then you cannot place a 9 in column 8. So you know that R6C1 is not a 9, and then it becomes easier to finish the grid. (queen_swaroop.png) Attachments ---------------- queen_swaroop.png (19KB - 4 downloads) |

Country : India | Administrator posted @ 2012-03-13 6:34 AM Diagonal Vision is now over. Link to score page - http://logicmastersindia.com/M201203S/score.asp Congratulations to flooser, janoslaw and TiiT for taking the top spots. 196 players participated and 154 of them submitted at least one grid correctly. The grids were tough, but it is bit surprising to see no submissions from many regular players (Rohan / Rakesh / Stefano ) Thank you everyone for participating. And Thanks Fred for all your efforts. Will wait to hear more from you. |

Some impressively difficult puzzles here, thanks. Thanks for participating. I'll comment about the difficulty when the test will be finished. I hope you had fun nevertheless. Fred I did enjoy several of the individual puzzles, which showcased some pretty creative execution of some of these variations. The Pointing Evens was probably my favorite, with a 1,2,3,4 theme where each of the numbers actually mattered, not just the small ones. Many other themes were nice too even if the puzzles were less friendly. I guess my competition complaint is that I particularly would not advertise "top players will be able to solve all sudokus earlier than 120 minutes" unless this really was a 90 minute test for people like Jan and Tiit and Kota or the winner Florian. My expectations were for some easier grids and even the first Argyle is hardly a 4-5 minute puzzle at least for me. It's possible that I'm not as good at sudoku as I think I am, or it's possible these puzzles are insanely hard. Probably some amount of both is true. But I was left with the same feeling as after Crazy Arrows of "wow, that test is insane." I loved the puzzles, but I don't know if they all belong in a competition. Maybe my views of 10 minutes is as hard as a competition sudoku should be and X- or Y-wings are as hard as a competition sudoku should get are wrong. This test certainly pushed them to the limit.

Country : India | debmohanty posted @ 2012-03-13 8:49 AM I'll let Fred put more comments later (and Fred, correct me if I'm wrong), but from our earlier discussion, I figure that the intention was that top players should be able to solve around 100 minutes. At least the test solver's timings suggested so. Prasanna was the first player to take the test, and looking at his score, we really thought that it is possible for top players should be able to solve better than what the final results suggest. Little did we realize that Prasanna has improved a lot in recent times. I realize that a statement like "It is expected that top players will be able to solve all sudokus earlier than 120 minutes." look certainly misleading now. [ I had put it originally in Sudoku A/B, where I thought I should let players know that it is more like a Sprint test and not otherwise. ] May be because of that line you started solving from the end, expecting that you are anyway going to solve all sudokus. Obviously, Fred's intention was never to mislead any player. |
