Posts: 30 Country : Poland | margareta456 posted @ 2014-07-23 8:54 PM have some question, because when i started i claimed as a begginer, because i was. now i have trained for some time and dont now if i should still start as a beginner or maybe seasoner. It's depend of our position in LMI ratings? Or i can change it due to my own feelings who i am? |

Posts: 145 Country : France | auroux posted @ 2014-07-23 11:19 PM The Arrow sudoku was indeed quite tricky -- not exactly beginner stuff in my opinion. Apart from that, on the classics I must have set a new record for the number of incorrect solves and broken puzzles. For some reason it took me 3 attempts to get each of the first two puzzles right... :( when I submitted all my answers after 12 minutes, little did I know that my final solve time would be more than twice that. Professional musicians often claim that a catastrophic general rehearsal is the best guarantee that the concert itself will go well, so perhaps I should take comfort in playing so badly just a few weeks before the WPC...

Posts: 80 Country : Canada | achan1058 posted @ 2014-07-24 3:45 AM The arrow was indeed quite nasty, especially near the end. I ended up having to use some kind of cycle strategy to eliminate a digit. This contest probably serve as my "most typo per question" as well, having entered 25% of the puzzles incorrectly. |

As far as I know, It's entirely up to you whether you want to compete as Beginner or Seasoner, depending on how you feel -- unless you have a high LMI rating, in which case you will be forced to compete as a Seasoner.Edited by auroux 2014-07-24 4:59 AM |

It's depend of our position in LMI ratings? Or i can change it due to my own feelings who i am? Once you have chosen to be a beginner, you can become a Seasoner in two main ways, 1. Using LMI ratings/performance on these tests/performance on Monthly tests, there are 4 criteria to get bumped up automatically. 2. If you want to make the change, you may request one of the admins to bump you up manually. |

Posts: 1 Country : India | coolsprite posted @ 2014-07-24 1:56 PM The arrow sudoku was the best. First time I am participating in such online sudokus. I could do all the other 7 online and had submitted and finished off yesterday. But today I took the Arrow sudoku on a printout and with a beautiful logic could complete successfully. Wonderful feeling... even if the timing looks awry.... Thanks once again. |

Posts: 12 Country : India | playee posted @ 2014-07-27 4:42 PM The arrow Sudoku was a real test to the logic. I submitted the classics well within time and also the 3 variants again in time but the arrow sudoku was a killer. The first time i submitted i got it wrong and then it took almost 100 mins extra to solve the puzzle correctly. I really enjoyed solving it finally though I lost on the time factor. Awaiting eagerly for the next beginners contest already. |

You can try in other browsers like chrome, mozilla or opera. Also you can try installing the browser Edited by Administrator : LMI does not use java. |

Posts: 739 Country : India | vopani posted @ 2014-07-29 7:41 PM This is the first Beginners Contest I've authored, and it was a sudden plan when Deb and I decided I should conduct one before the WSC-WPC fever sets in. I hate creating Classics (like many Authors), but since I had no choice, I pushed myself and created 3 Classics (Classic 1, 2, 3) each having a different kind of solve. I think I got tired then and created a simple fourth Classic with the 'triplets' theme :-) Trio Sudoku: It was my personal favourite. It took me longer to create with a 1~9 diagonal theme than any normal Trio, but I was satisfied with the puzzle. It had a nice solve and I'm sure all of you enjoyed solving this :P Diagonal Sudoku: I like Diagonal Sudoku with 3 blank rows, it forces solvers to put in those digits using the diagonal. Maybe next time I'll try 4 blank rows! Extra Region Sudoku: Nothing special here, just a pleasant design to see (I think!) and a simple symmetry of givens. I didn't want too many digits to be filled using Classic rules, and I think that stands true for this puzzle. Arrow Sudoku: There must be something to test solvers, right? I admit the Arrow was not trivial, it had a tight opening in the bottom-left of the grid, but after that, the solve is very smooth. Lots of players struggled solving this variant and I've posted one (the easiest I could think of) solving path. You can have a look here: http://rohanrao91.blogspot.in/2014/07/beginners-contest-on-lmi.html I'm glad to see 295 participants, though crossing 300 would've been nice :-|, but thanks a lot for participating and I hope you enjoyed. Congrats to the top-3 Beginners: sworls (USA), anti-inequality (Turkey) and ViRa (India) and the top-3 Seasoners: Kota (Japan), Timothy (France) and deu (Japan). Feels nice to finally conduct a Beginners Contest and hope to see many more contests and sudokus in future! |

Posts: 337 Country : Switzerland | Fred76 posted @ 2014-07-29 8:31 PM Rohan Rao - 2014-07-29 7:41 PM Lots of players struggled solving this variant and I've posted one (the easiest I could think of) solving path. You can have a look here: http://rohanrao91.blogspot.in/2014/07/beginners-contest-on-lmi.html I find your explanation about the 1 in R8C4 quite confusing. I imagine it can be struggling to try to "solve" these 2 arrows independently. If you take care of both arrows together it becomes very easy: Considering that the maximum of the sum of both cells R9C23 is 4+5=9, then the sum of the three cells R7C45 and R8C4 has to be <9, hence must contain a 1, which can be placed only at R8C4. There is even no need to write candidates ;) I liked this sudoku very much, and I remember I explained this "technique" about taking care of several arrows together in a Swiss federation newsletter (...a bit sad that other swiss players taking part didn't solve this sudoku). See you in London Fred |

Posts: 52 Country : India | gaurav.kjain posted @ 2014-07-29 10:13 PM The way I got it was R9 C23 could be from 3/4/5 so other than 5 , 3/4 has 1 in their addition combination. which has to in one of the cells even if 5 is one of the cells. so 1 has to be in one of the 4 cells(R7 C45 and R8 C34), which can only come at R8C4. Since only single 1 comes in these 4 cells which will also provide other clue, that is R9 C23, one of this should contain 5. Edited by gaurav.kjain 2014-07-29 10:16 PM |

There are multiple ways of figuring out the bottom-left... but either ways, I think it does take a while to identify the opening, especially when you are solving under time-pressure! |
