Posts: 170 ![]() ![]() ![]() ![]() Country : Germany | rob posted @ 2015-11-03 1:57 PM The rules for the classic snake state that the centre will be given, but the example doesn't show it. Is it correct that all four classic snakes will have head, tail and centre given, but no total length? Just to confirm, for the loop snake, you put in a snake, and then the puzzle is solvable as a "simple loop"? For the coded snake, may there be gaps in the set of clues, and is 0 permitted? For the linked snake, does the masyu white pearl rule extend into the neighbouring quadrants? I.e., if there's a white pearl on the edge, and the snake passes this orthogonally to the grid edge, does the cell in the next grid count as a possible turn? Thanks! |

Is it correct that all four classic snakes will have head, tail and centre given, but no total length? Good catch. I believe the instructions need to be corrected. The example is correct, the centre will NOT be given. Just to confirm, for the loop snake, you put in a snake, and then the puzzle is solvable as a "simple loop"? Yes, that is correct. For the coded snake, may there be gaps in the set of clues, and is 0 permitted? The range of numbers possible for the alphabets will be given. Eg: If there are 8 alphabets, range can be 0~7, 1~8, 1~9 (with one missing), etc. It will be given. For the linked snake, does the masyu white pearl rule extend into the neighbouring quadrants? I.e., if there's a white pearl on the edge, and the snake passes this orthogonally to the grid edge, does the cell in the next grid count as a possible turn? The rules apply ONLY to that particular quadrant. The puzzle is such that there won't be any confusion/discrepancy like the example you mentioned :-) |

Also, croco-puzzle is currently running a series of snake variants: http://www.croco-puzzle.com/Ue-Raetsel/serie.php?serie=60 (though the rules are in German, but feel free to ask). |

May the loop go through black cells (the given ones, not the snake)? The loop is not necessarily unique. The loop CANNOT go through given black cells. However, for this contest, the loop WILL BE unique in all the puzzles, and this has been added to the instructions. |

Maybe you can show us a solution which doesn't match the answer key? I cannot see an alternate solution. |

Posts: 668 ![]() ![]() ![]() ![]() ![]() Country : India | swaroop2011 posted @ 2015-11-07 11:43 PM Nice set of puzzles. Fun test. I felt as this test anyway doesn't count for ratings, I would have preferred bit more time (90 min test). I was able to solve all puzzles but may be slow, but i continued solving after the time is over and I realized few of the high pointers later were very easy in comparison to few other low pointers. But anyway completed all puzzles. May be took 30-40 min more considering I took 20 min to do Coded Snake big pointer (was doing lot of mistakes due to some un-necessary assumptions). Thanks ashish for this set. |

Oh it doesn't? That's a pity, why not? Annual contests have never been included in ratings. I'm sure there has been a discussion somewhere hidden deep inside the forums, I don't quite remember now. Will let someone else answer :-) |
