HOW TO PLAY

1. Fill every white square with a digit from 1 to 9.
2. The dark squares hold the clues. A number above the line is the sum of the white squares to its right. A number below the line is the sum of the squares underneath.
3. No digit may appear twice in the same run of white squares.
4. Tip: some sums can only be made one way! 3 in two squares is always 1 + 2, and 17 in two squares is always 8 + 9.
5. Tap a square, then a digit. ✏️ Notes keep track of maybe-digits. A clue turns green when its run is right.
6. Solve it without hints for 3 stars ⭐⭐⭐. Every puzzle has exactly one answer.
