Normal Sudoku rules apply: place the digits 1–9 in each row, column, and 3×3 box.
The black arrows are A-Sums. The digit at the base of the arrow determines how many digits in the indicated direction must add up to the specified sum.
For example, if there is a 7 on an A-Sums arrow, 3▶1 2 4 is valid: the 3 indicates to sum the next three digits, and those do add up to 7. However, 2▶4 3 and 1▶7 also work.
Solution code: Top-left 3×3 box in reading order.
