Normal sudoku rules apply.
Digits on a green line differ by at least 5 with their neighbors.
Digits in a cage do not repeat and must sum to the number in the top-left corner.
Digits separated by a white dot are consecutive. If a dot is on a corner between four cells, it applies to both diagonal pairs.
Solution code: Row 5
