Country : Czech Republic | But in the IB there is NOT written, that all possible locations of pairs are marked, so I think, that the puzzle is correct. |

Country : Slovakia | In the 17th puzzle - Outside or Skyscraper - it seems that both possible choices may be used at once (the clue "1" in 8th column). Am I right? It is not so obvious from the instructions.
Thanks |

Thanks Yes, one clue can act as both Outside clue and Skyscraper clue. So, at least, one type of clue must be satisfied. |

Country : India | Same is true for for Odd Even Frame as well. For example, if 4 is the clue outside, the first 3 digits could be 1,3,4 in any order. |

Sorry for bothering you, I was just wondering what is the use of one single C in the whole grid?
Unless the instructions mean that 'if a 5 is used for pair D, it can't be used for pair C'. But that is not how I read the instructions; I interpreted it as 'if 56 is usded for pair D, the combination 56 can't be used for C. But 15 is possible for C, or 26.
So maybe I interpret the instructions not correct.

Hi Richard, this is correct interpretation. If D represents 56 (or 65 ), C cannot be 56. C can however be 15 or 26 (or 34 ).

You have answered that yourself. If you determine that D is 56 (or 65 ), C can never be 56. It does not matter how many times C is present in the grid. It could be once or more than once.
Hope that rules in the pdf are clear and they state the same thing. |

Is the hole monday included or only til noon? Or yet to be determined? It will be open entire Monday (GMT time ), like other LMI monthly tests. |

It's just to point out that only the marked 3x3 boxes count and not for example R2C4-R2C6-R4C6-R4C4. If they were to only say, somewhere in the grid there is a magic square, then this square could also be legal. |

Maybe the word "outlined" should be there instead of "given" |

Country : France | To answer a question that was asked on http://sudokuvariante.forumactif.com, although I am quite sure of the answer: on this same puzzle, is it allowed that two or more regions each form a magic square? Also, is it allowed to find a magic square somewhere else in the grid, as far as the initial constraint is fulfilled?
Thank you. |

Thank you. At least one 3X3 outlined box is a magic square. Once the initial constraint is fulfilled, there are no restrictions. |

Is it online solving Yes, online solving will be enabled.
However, please note that for some sudokus you might need external marking (e.g. Coded Pairs ). You cannot do those kind of markings with online solving. |

May I ask how we will need to do external marking? Since the sudoku type in question has all necessary markings already given to us in the puzzle. What I meant was :
In coded pair, you might want to write A = 23 somewhere. If you are solving on paper, taking these notes are obviously easy, but there is no facility to note such things in in online solving.
Similarly you might want to draw a line in Linked Classics between the duplicates rows across the grids. |

Country : Iran | Mahyar posted @ 2013-02-02 1:26 PM I have problem with Puzzle "Coded Pair".
In letters C and B, number 1 is common. I want to know that in different letters, all the pair numbers should be different or one them can be equal like the example?
i.e. you mean that only pairs "should not be equal" and if one number in the pair become equal, it is possible. |

i.e. you mean that only pairs "should not be equal" and if one number in the pair become equal, it is possible. As replied in above post, 2 letters can have 1 common digit. But both the digits can not be same for 2 letters.
If letter D represents 56 (or 65 ), letter C cannot be 56. Letter C can however be 15 or 26 (or 34 ) or whatever else.
