The brief
Standard sudoku rules apply: each row, column, and 3x3 box must contain all the digits from 1 to 9.
Digits on an arrow must sum to the digit in the attached circle. Digits may repeat on an arrow if allowed by the other rules.
Clues outside the grid show the sum of the digits along the indicated diagonal. Digits may repeat along the diagonal if allowed by the other rules.
