Country : Indonesia | To clarify in puzzle 2 (Minefields), the numbers are treated as empty spaces, right? (And hence a numbered cell in the small grid doesn't have to correspond to a numbered cell in the large grid; it just needs to correspond to an empty cell in the large grid, numbered or not.) Otherwise there's an obvious contradiction. But clarifying...
And for puzzles 10 and 11, are the bounds M,N included? Or to be more explicit, take puzzle 10 (Loop Between the Polyominoes): is the maximum allowed grid size 26x26 or 27x27?

With my knowledge of English is hard to understand a question about Puzzle 2. I hope that Prasanna understand it and respond.
In Puzzle 10 the three maximum allowed grids are 26 x 26, 25 x 26, 26 x 25. M, N in puzzles 10 and 11 are not related. |

Country : Indonesia | I mean, can a number inside the small grid correspond to an empty space in the large grid or must it correspond to another number? |

Country : India | For My Line of Puzzle 4, does the reverse rule apply? In the sense, if the line makes a turn at a cell, should that cell definitely contain a number? |

A number inside the small grid can correspond to an empty space in the large grid. |

I answered a similar question from Matus:
In cells without digit or "?" where the line turning angle lengths may be different. But may also be identical. |

In example pentominoes can be only into 4 x 4 area. |

Then why does the last column contain 3 at the top when it is not part of the 4x4 area? What is the significance of that 3?

The Astronomer, as is normal vision, can see in (tending to ) infinite angles. So the only thing to keep in mind is that there should be X number of visible planets and X number of invisible planets blocked by the visible ones. The angles in the example are just to get a better understanding of the visibility block. |

Country : United States | Just as a formatting note, it would be awesome for puzzles like 3 if the numbers were printed smaller and in a corner so you could write the translation in the box without trying to overwrite the digits. Going well so far, but that will end when I reach the optimizers. :) |

Country : Indonesia | In puzzle 4 (Across 4 Grids), might the quadrant with black cells actually be My Line? Like, it's just a regular My Line with some removed squares, and the other quadrant is actually the Diayajilin. |

Yes this is possible. You need to prove which is which. |

Just saw this. That 3 would come into play IF you prove that the 4x4 area is inclusive of it. It can also act as counter-proof that it cannot be a part of the 4x4 area. The important part to remember in both cases is you first need to prove where that area is, so the added clues help in restricting that. |

Country : India | I have been participating in your sudoku contests since couple of years and love them. Actually they are the highlights of every month. I have a request please. Could you have the sudoku Classic and Variants contest every month in addition to whatever puzzle contests are on ? The puzzles are quite beyond my ken and almost all of them have to be solved offline which is a bit of a challenge for me. Could you please bring back the monthly online sudoku contests ? |

Country : India | A doubt in 10th Puzzle Optimizer.
It says maximize the are of rectangle. So does that mean if someone has area 26*26 and other has 25*26 but later one has more empty squares.
Does still 26*26 best ? |

Some part is fine. The invisible ones must be fully invisible. |

Hi. We will definitely continue with the Beginners Contest in Sudoku and Puzzles in the forthcoming months. In the meantime, you can participate in the Monthly contests so that you will be able to know the different types and difficulty levels in World Championships. Also, you can participate in April Contest by Riad, which is currently running. This has few Sudoku variants, which will definitely interest you. |

Country : Indonesia | In the quadrant with My Line, all cells (except the black ones if it happens to be the bottom-right) should be passed right? As in, there's no extra "black square" or anything to the quadrant with My Line? |
