Rules:

Normal Sudoku rules apply.

The grid is partially covered in fog. Placing correct digits reveals clues in the surrounding 3x3 area.

Digits joined by a red V sum to 5. Digits joined by a blue X sum to 10. Not all Xs and Vs are given.

Adjacent digits on a king line must form a valid king move on a 3x3 Numpad. For example, 1 can only be adjacent to 2, 4 or 5. A longer run on a king line could be 123685486.
