Do(o)ts and Sum Blue
by Sandra & Nala
- Kropki dots
- Region sum lines
The brief
Normal 6×6 Sudoku and „Sudooku“ apply.
Blue lines are region sum lines. For each line, digits on the line have an equal sum N within each box it passes through. There are 4 lines that cross another line in this puzzle. These are to be treated as independent lines. (So there are 8 lines in total here)
Cells separated by a black Kropki dot are in a 1:2 ratio. Sets of digits separated by a black Kroopki Doot (a long, ellipse-looking shape) must have their respective sums be in a 1:2 ratio.
Cells separated by a white Kropki dot are consecutive. Sets of digits separated by a white Kroopki Doot must have their respective sums be consecutive.
Not all Kropki or Kroopki Do(o)ts are necessarily given. There is no negative constraint.
