Rules:
Normal Sudoku rules apply. Shade some cells so that all areas of orthogonally connected shaded cells are rectangular and all areas of orthogonally connected unshaded cells are not rectangular. (Yes, a square is a rectangle.) A digit in a circle equals the size of its group of shaded/unshaded cells. Digits may not repeat within such a group, and a killer clue is the sum of the digits in the group. Note: a group can have zero, one, or more than one of each clue type.
Solve:
Lösungscode: Column 5 (top to bottom, no spaces, 9 digits)

Quite a lot of people have solved this so it's probably just me, but I found the rules ambiguous in that they don't exclude the possibility of different shaded/unshaded regions being adjacent, and yet this is clearly the case. So might be helpful to clarify for people like me.
