Kakuro
Fill crossing runs to match their sums.
How to play Kakuro
Each white run uses distinct digits 1–9 that add to its clue. Crossing runs share a digit.
Below-diagonal clues sum downward; above-diagonal clues sum to the right. Notes help track possibilities.
Example: Across 4 in two squares → 1 + 3; 2 + 2 is invalid
