Empty X-Sums

Rules:

1. Normal Sudoku rules apply. The digits 1-9 appear exactly once in every column, row and 3x3 box.

2. X-Sums Variation. Each row and column marked with an arrow must have the first X number of cells sum to a specific two-digit total. The two-digit total reads as the first two digits from the clue. The closest cell is the tens value, the second closest is the ones value. The number of cells that add to this total is the digit in the third cell from the clue. (e.g. A row with digits 2-1-6-3-4-5-7-8-9 would be valid as the first 6 cells sum to 21.)

3. Box and Row Correlation. Boxes are numbered left to right, top to bottom. For each of the digits 1-9, in box 'N', the digit 'N' is in Row 'N'. (e.g. In Box 1, the '1' is in Row 1.)
