Cross-sum logic — fill 1–9 to hit every clue
Tap a white cell, then tap a number.
How to Play
- Fill every white cell with a digit from 1 to 9.
- Dark clue cells show sums: the number in the bottom-left is the target for the across run to the right; the number in the top-right is the target for the down run below.
- Digits in a single run must be unique — no repeats in any across or down sum group.
- Tap a white cell to select it, then tap a number (or press 1–9 on a keyboard). Use Erase or Backspace to clear.
- Mistakes highlight in red. Fill every cell correctly to win — faster solves earn more points.
15 = the down run sums to 15. 11 = the across run sums to 11.
