A-Sums Sudoku
(Published on 27. February 2026, 19:23 by Timwi)
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 sum specified on the arrow.
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.
