- Normal sudoku rules apply, i.e. each row, column, and 3x3 box has to contain the digits from 1 to 9 once each.
- Killer Lines: Digits on a line may not repeat and must sum to the clue attached to it.
- Up to N-sums: A clue outside the Row or Column N indicates the sum of all digits up to the cell that contains the digit N. (The digit N itself is not included in the sum.)
