Build Your X-Sums

Rules:

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

2. Diagonals. The digits 1-9 appear exactly once on each of the main diagonals.

3. German Whisper Lines. Adjacent digits on a green line must differ by at least 5.

4. Kropki Dots. Cells seperated by a black dot are in the ratio of 1:2. Cells seperated by a white dot are consecutive. Not all dots are given.

5. X-Sums Variation. Each row, column and diagonal 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.)
