Solving Tip: Start with the shortest diagonals (2-3 cells) as they have fewer valid combinations. A 2-cell diagonal with sum 17 can only be {8,9}, immediately placing both digits. Use these anchor points to constrain longer diagonals.
Constraint Tip: When two diagonals intersect at a shared cell, the digit in that cell must appear in valid combinations for both sums. Cross-referencing intersecting diagonals dramatically reduces possibilities and often unlocks the entire puzzle.
