Rules:

Standard Sudoku rules apply. Fill in the grid with the numbers 1-9 so that the numbers are not repeated in each row, column, and each 3x3 area (box) separated by a bold line.

X-sum rules apply. Clues outside the grid indicate the sum of the first X digits in that row/column where X is the closest digit to the clue.
