A year ago I published my first puzzle on this platform, and felt like celebrating that today. So, here is a direct sequel to that puzzle, with a similar theme but a trickier rule set.
Rules:
1. Normal sudoku rules apply: Place the digits 1-9 in every row, column and 3x3 region once each.
2. Digits along a line may repeat and must sum to the attached value.
3. XV: Digits separated by an X sum to 10, while digits separated by a V sum to 5.
4. Cells separated by a chess knight's move can't contain the same digit.
