- Region sum lines

The brief
- Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box. - Little Killers: Clues outside the grid are the sum of the digits along the indicated diagonal. Digits may repeat if allowed by other rules. - Sum Line: Box borders split blue lines into sections, and the digits on those sections must sum to the same value.
