Mozhet li 2 byt' v zeljonoj kletke pri otrazhenii vpravo ili vniz ili tol'ko po diagonali? 3 mozhet byt' v zeljonoj kletke TOL''KO pri gorizontal'nom zerkale (vniz-vverh)? |

Try to find openings, applying the rules. Try to think "If .... then what happens, is any rule violated." And if you are stuck, save your work and come back later. |

Posts: 4 Country : The Netherlands | Eisbaer posted @ 2015-04-09 5:11 PM I have a little question about puzzle 10... In the requested sentence there are two "I' 's and one time the digit 1. But it looks like there are three same characters "I" (or 1?) in the grid? Could all three characters be used for the digit 1? |

Posts: 145 ![]() ![]() ![]() Country : France | auroux posted @ 2015-04-09 10:25 PM Just to make sure -- in "Tools", the answer key only describes whether the edges of the grid along the given row or column are occupied (and if so by what tool) or not, correct? More precisely: what would be the answer key for the second row in the example? Am I right that it would be -----HH---- ? (i.e. the edges that are "inside" the ladder are unoccupied and so remain "-" in the answer key, even though there is a ladder) ? |

Yes, for the second row in the example the answer is recorded correctly. |

Couple of notes 1. In Puzzle 10 (LMI Contest 2015 at LMI) we had to manually determine the end point of the line in several cases. Please check if your submission is different than what is intended. 2. Riad is still solving all the Puzzle 12 (ROMAN COOL-L-L) submissions. If you notice any grid is invalid, please post here. |

Posts: 187 ![]() ![]() ![]() ![]() ![]() Country : New Zealand | kiwijam posted @ 2015-04-12 2:31 PM The Player13 grid is interesting. The only way to get four adjacent 200s is with: LOLOOLOOL OOLLLOOLO OLOOLLLOO LOOLOOLOL or its mirror image. (this is not simple to prove!) So that fixes the top 4 rows, and if the bottom 4 are the same pattern then the solution must be: LOLOOLOOL OOLLLOOLO OLOOLLLOO LOOLOOLOL LCLLCLLCL LOLOOLOOL OOLLLOOLO OLOOLLLOO LOOLOOLOL If the mirror image option is used below then no solution is possible. So the Player13 grid is fine. |

I ask everyone to look at the preliminary results and report if something disagree. I congratulate James, Tomoaki and my Ukrainian friend Sergey with a victory in the April contest! |

Posts: 23 ![]() Country : Australia | flk posted @ 2015-04-12 5:37 PM Thanks Riad for many wonderful puzzles. These were certainly very difficult and had me frustrated for many hours! With so many unique rules, it was easy to make a careless mistake early on in a puzzle, not be sure where you had erred, and have to restart. But, it was certainly fun and had me focused intently for a long time. Unfortunately ran out of time to tackle the last optimiser! On the results: it looks like I did not receive any points for my COOL optimiser, and Christian may have been given the points in my place. Thanks again. |
