Standard sudoku rules apply: each row, column, and 3x3 box must contain all the digits from 1 to 9.

Digits in each cage must sum to the number in the top left corner of the cage. Digits may not repeat within a cage.

Clues outside the grid give the sum of the digits along the indicated diagonal. Digits may repeat if allowed by other rules.
