Prasanna,

Are there 2 solutions for the Polyominos example? Or am I missing something?

I'm a bit unclear on the rules for Doubled Japanese Sums. In particular, the central black cell appears to break the 12,? direction into 2 parts. In such a situation would it be possible for there to be a repeated digit in the two parts. In other words, if the outside clues were different, would it be possible for the cells containing 4 and 7 in the existing solution to contain the same digit?

You are right. It will be fixed in version 2. Thanks!

It would be possible for the cells containing 4 and 7 to contain the same digit. I'll add a note making it explicit that the black cells break cells in the relevant directions. As an extension, the cells containing 4 and 9 in the existing solution cannot contain the same digit.

5 hidato. what do you mean with "every two consecutive numbers must be placed in cells sharing edges OR SHARING CORNERS ? can two such cells be in contact only in a point? can you give such an example?
8 double japanese sums. why the clue 12 is not followed by the clue ? and this is instead repeated on the opposite side? Is the black cell in the middle not a shaded cell, but rather has something special?

Can you check the round notes? An example is given of how cells could share just corners (the right and left cell, and the top and bottom cell each share just a corner).

I assume that in Polyominos shapes must not be places in cells containing numbers. Is this correct, because I think it is not stated in the rules.

Also, I'm a bit confused by the general round note regarding structures that allow for solely diagonal touching of cells: In the example image, would each cell would still be considered to touch two other cells by a side (as in the last sentence of Polyominos). And also in the example: would the right and left cells be considered touching each other (maybe diagonally)?

For puzzle 6 Adjacency Loop I assume, that the loop must not cross itself, as otherwise the example wouldn't have a unique solution. However, it is not stated in the rules, so maybe you could clarify that?

Regarding Doubled Japanese sums: From above I understand that black cells (or parts in the diagram) split the diagram in separate parts with regards to clues and repeating digits. However, I think it should say "each digit appears at most once in each direction" not "exactly once". Or do I miss something due to limited grasp of the language?

(Sorry for posting the questions one by one. I immediately wrote a comment once I stumbled on the question.)

Ah right, the 3 should become a 2. Will get this fixed. Thanks!

Polyominoes: The rules say "different shapes can't touch each other by a side", however, they don't say if SAME shapes can touch each other by a side. I'm assuming the intended rule is that no shapes touch on an edge, regardless of whether they are the same or different shapes.

Simple Kompass: The rules should probably make clear that every cell is part of a region, and every region has exactly one cell that is divided into triangles.

Adjacency Loop: Can the loop cross itself in shaded cells?

As a separate question: Does the solver have to indicate how the loop behaves in shaded cells to get full points?

Simple Kompass:
A little confused by the count of the bottom-left hexagon.
If this is based on Compass, shouldn't the "1" count be 3 or 4?
Which segment of the divided hexagon pie would the last two cells (of the long tail) count for?

Hidato:
Is it sufficient to draw a path instead of filling out every number?
