Complete the borders to make this a jigsaw sudoku solution ...



Is the completion unique if 180-degree rotational symmetry is not required?

Is wrap-around allowed (toroidal, cylindrical, Moebius strippial, etc)?

No, it's supposed to be "standard" jigsaw sudoku. That solid black line around the 9x9 is part of the given borders.

Even if symmetry is required, there are at least 2 solutions...

Solution 1

Solution 2

Don't know which one will produce a harder puzzle though...
