Location: The Netherlands | One question for the battleships puzzle. Can a ship cross over the edge of a grid into another grid, so that in one grid it is a smaller size than in another grid?
So say in the example puzzle: in the right top grid a size 3 ship lies in R5C123 and then at the same time in the left bottom grid a size 2 ship lies in R2C45.
Also a clarification about the star battle puzzle, I assume that stars which belong to different grid can touch diagonally, like in the battleships example?

Location: Russia | One question for the battleships puzzle. Can a ship cross over the edge of a grid into another grid, so that in one grid it is a smaller size than in another grid? Yes, it can. Ships don't have rounded corners and you could consider it as a simle set of marked cells for each grid.
Also a clarification about the star battle puzzle, I assume that stars which belong to different grid can touch diagonally, like in the battleships example? Touching of stars which don't belong to the same grid is possible. |

Location: Russia | All participants could try the puzzles of the last Moscow Cup. See here. I made this round using the same idea of overlapping grids. The file is in Russian but mostly puzzles are well known:
1. Tents
2. Yin-Yang
3. Batleships
4. Heyawake
5. No touch - Write digits 1 to 7 into the grid (each digits could be used any times). Digits cannot touch each other. Numbers outside show the sum of digits in the corresponding row.
6. Tetroscop - Place the complete tetromino set - elements cannot touch each other even diagonally. Clues show the number of occupied neighbouring cells. Pieces could be rotated and reflected.
7. Minesweeper - 17 mines for each grid. |

Location: United States | In the bottom grid of the battleships example, if we toggled the first two cells each of R3 and R5, would we have another solution? |

Location: India | I guess the Moscow Cup puzzles were of an easier difficulty, which is good for practicing the basic steps in the samurai grid. I have fun on Samurais, though I'm not that good at the sudoku version. Hopefully I'm good at the puzzle version :P |

Location: Slovakia | In Hitori, the instructions say that all the unblackened cells should be connected. Is it valid for the whole puzzle (5 grids) or always for one small puzzle? |

After thinking about it, it seems to be slightly impossible to have one grid without connected white cells and the others with connected. So sorry for stupid question  |

I had the same doubt earlier. But, I wanted to ask by posting an image and thats when I realised I couldn't create such a case (unless the overlapped region consists of just one cell).
Same goes for Yin Yang too. |

I couldn't find alternate solution. Describe if you have it.

Yes, there was a mistake in this example, which was found by Deb at the last moment and I've corrected picture without checking uniqueness. |

Are you logged in on the puzzle page? If you're not, there won't be a start button yet. If you have three boxes to fill in name, password and country, you have to log in first and then the start button will appear. |
