About Sumline: Cross Sums

Sumline is a cross sums puzzle you can solve at your own pace. Choose from three board sizes, use notes to explore possibilities, and return for a date based daily challenge.

How to play

Select a light square and enter a digit from 1 to 9. The clue at the left is the sum of the across run; the clue above is the sum of the down run.

Rules in this version

  • Each light square holds a digit from 1 to 9.
  • Each across or down run must add up to its clue.
  • A digit cannot repeat within the same run.

Tips for playing

  • Begin with two square runs whose sums are very low or high.
  • Use intersecting runs to rule out candidates.
  • Pencil in possibilities before committing to an answer.
