Country : Indonesia | This is an annual contest. Forsmarts annual contests, and if I recall correctly Fillomino-Fillia 2, weren't counted for Puzzle Ratings, either. |

Country : Serbia | Nikola posted @ 2015-04-03 4:34 PM Very nice stuffs again! I have two questions:
4. MIRRORED SUDOKUS
I don't understand the rule: "All cells with digits which, after mirroring, become the same or other digits (in any of the other grids) are marked by green". Why in the solution of the example not all the same mirrored digits are marked by green? And how to solve an example when we have only one given digit? Also a thinking why digital shapes are given? Must be I miss something in this puzzle.
11. NUMBERED SNAKE
There is no limitation about sequence of the numbers for this puzzle. I suppose we need to place the numbers strictly from 1 to 45 in creasing order. Am I right? |

Hi Nikola,
4. In the example only 0 and 1 can be reflected itself in each of four grids. The number 3 may be mirrored in 3 or letter E. Therefore, one given digit enough to solve an example.
11. You are right.

Any cell will have three possible "mirror" cells, one in each quadrant. If any one or more of these three represent a valid number (0 to 5, digital shape ), then the original cell will be shaded green. If not, it will be shaded white. Edited by rakesh_rai 2015-04-03 8:49 PM

Country : Serbia | Nikola posted @ 2015-04-04 2:37 AM Clear now, thanks. Yes, "reflected" is key word and the rules always say "mirrored". I don't know why those two words are not synonyms in my mind.  |

Country : Serbia | Nikola posted @ 2015-04-05 3:54 PM To follow up on the previous question. Is it allowed to make the crossings on the cells with the letters? In that case, if the letter has remained out of the loop, is it an empty cell? |

Country : France | Hello. Very pleasant contest : I like !
For puzzle 11, the answer is controlled as "- or number (10 times)" but the grid is 11x11 : so I suppose it would be "- or number (11 times)" ? |

I have the same question. For example, along the line we must go through two letters 'A' : is it possible to go through the same letter 'A' 2 times (by crossing ), and to avoid the second letter 'A' ? |

No Stefano,
This is unacceptable. |

The line should pass through each letter. The letter can not be remained out of the loop. |

Perhaps such conditions would make the puzzle more difficult. But I assumed that the line goes through all the characters. |

Country : France | auroux posted @ 2015-04-06 6:25 AM In the answering form, for puzzle 11, I think the answer keys need to be of length 11 not 10 as claimed by the format verification code (which warns me that my answer keys are not of the right length).
(In general, many of the answer keys seem trickier than necessary -- really, counting the C's? diagonals that go in the opposite of the usual direction? --, but it's too late to change them). |

I'm a pronounced left-handed. Maybe because I offered unusual diagonals? |

It is not necessary for the line to start at cells with A and end at cells with I. |
