Hi, I have a doubt with respect to the puzzle "Arrow Connection". One of the rules mention "A direction is given if and only if it is used". What does this imply? Why are directions not shown in all boxes wherever the loop traverses?


This rule applies only to clued cells. So, for each cell in the grid, either "all possible directions are given" or "no information is given" must be true. I hope this is clear.

Yes, that cleared my doubt.

Not necessarily. There may be some unused cells.

In Arrow Connection if an arrow appears twice around a cell, is an arrow given twice or once. I know it's not possible in the example as the start and goal are in the corners, but with different start and goal points, this could happen. For example, when you draw a spiral.

Good question. An arrow is given only once even in such cases.

In Divided sum cross it says " no digit repeat within a single group divided by black cells".
so if clue is 7:_ _ _ _ _ :17 (5 cells blank in between). so is all 5 cells considered one group or is considered as two groups ?

All 5 cells are considered as one group. So, solutions like 7:1 6 | 4 7 6 :17 (two 6's in one group) are not allowed.

    I couldn't find elegant way to solve Yin-Yang top. (ToT)
    My favorites were Number connection bottom and Four winds with blanks bottom.

    Hello Ko (and others),
    Please see my diagram.
    I have put all the 'easy' logic in first.
    Then I see the two red rectangles have the form:
    B.B
    B.W
    which must become:
    B.B
    BWW
    Later, I use the same rule in the green rectangles.
    I think that is enough to finish.
