I used to think I'm horrible at snake, and leave it whenever it appeared in competitions. Not gonna do that from now, found these solvable and fun and got quite a morale boost. :) |

Posts: 183 ![]() ![]() ![]() ![]() ![]() Country : Turkey | yureklis posted @ 2011-11-29 7:29 PM Hi, You were very kind about my puzzles, thank you very much. Last year I wanted to organise a Snake puzzle competition. I don’t know why, or I don’t remember exact reason in my mind, I asked some puzzlers from LM Deutschland, and Jörg Reitze agreed to help me about holding Snake competition under LMD. Because there are some rules, that only LMD members can hold a competition under LMD title. By the help of Jörg I had a chance to show my Snake puzzles. After the competition I was sure that I would make again, and this year Deb and LMI give me a chance to hold Snake contest 2. Thanks a lot! About Instructions: From my side, the most boring thing in preparing a competition is arranging a proper instruction booklet. So mostly I try to use available instructions which I used in previous contests. So most of the examples and explanations in this contest are coming from previous one. So this is the reason of diagonally/at a point differences in explanations. Answer Format: I remember that last year, some competitors (I remember Nils’ comments, and he was right) mentioned that some puzzles’ answer formats are annoying, it is easy to make a mistake. So this year I wanted to be clear about answer formats. First idea in my mind was to use Tapa answer format. But after Thomas Decathlon 2011, his answer format seemed better to me. So I used it. I tried to make submitting answers easier for competitors. Of course I had to be sure that all arrows referred to last solving steps. So some competitors made tiny mistakes (one or two wrong digits) even if they almost solved the puzzle; like Masyu Snake, Sea Serpent, Calculusnake. Instant Grading: If I remembered the availability of this system before the competition, I’d surely want to use in this competition. Congratulations to Ulrich! He is a great snake solver. Also last year he got the first place, he solved 16 snake puzzles in 90 minutes (1.31.27 exact time) [2nd Michael Ley 1.32.45, and 3rd Philipp Weiß 1.45.21]. This year Ulrich has solved 16 snake puzzles in 95 minutes. As last year, 2nd and 3rd top solvers finished all puzzles in 120 minutes. Congratulations to Palmer and Nikola! Some statistics: - The puzzle solved by least competitors was Serpentine. It was solved by 31 competitors. - The puzzle solved by most competitors was First Seen Snake. It was solved by 109 competitors. - The puzzle with the highest rating was Calculusnake (9.0) and the puzzle with the lowest rating was Serpentine (6,69). - The puzzle submitted with the highest accuracy was Schlange (%100, 59 competitors), lowest was Masyu Snake ( %76.2, 32/42 competitors) Thanks a lot for participation, Best, Serkan |

I don't know what it is with me and extra time, but somehow it brings out the best in me. I pushed out the 2 highest rated puzzles in the last 10 minutes. This seems to keep happening whenever there is extra time. Guess I work better under pressure. |

Posts: 1 Country : Australia | nathanm posted @ 2012-02-08 2:50 PM Is there a solution booklet available? Just going through these old tests for fun, but found the solution for "The Persistence of Memory" is not unique, which makes me think I may have something wrong? The two grey shapes on bottom right i'll call 'd' and 'NE arrow' can seem to have a number of routes through, and since there's no other shapes like them on board, doesn't seem to constrain this? |

Posts: 23 ![]() Country : Australia | flk posted @ 2012-02-10 1:50 PM Here is my solution. I haven't verified that it's correct but I believe so. I think those two areas were the last to be placed, starting with the bottom left square of the 'd' as an x, as it is touched by the snake, and then the whole path is constrained.
