very very nice logo, who designed this ? David ?

The logo was designed by my daughter Kate and now she's very happy the logo is liked.

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?

Can the Minesweeper puzzle have the possibility given below? The number satisfies each grid independently, but not together.

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.

Your picture is correct. Each grid is satisfy the rule.

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.

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?

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

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.

All rules must be valid for each single grid. But of course sometimes it implies some restrictions for whole puzzle.

Top grid of Hitori. Is there a 2nd solution by colouring the opposite 5 in row 3? Is there actually a 3rd solution there by colouring the opposite 1 (row 2) and 5 (row 3)?

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.

And you should have mentioned that it is me who suggested the 'correction' as well. Sorry about the blind suggestion.

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.
