Rules:
Standard Sudoku rules apply. Put the digits from 1 to 9 exactly once into each row, column, and box.
Sequence Line: Each grey line contains digits in order with a constant difference. E.g. 1-2-3; 2-5-8 or even 3-3-3 are valid lines.
Little Killer: Digits outside the grid are equal to the sum of the digits along the indicated diagonal.
