It's a crossword made of numbers. Fill every white square with a digit from 1 to 9.
- A clue square splits in two: the number top right is the total of the white squares to its right; the number bottom left is the total of the squares below it.
- No digit may repeat inside one run (one unbroken line of white squares).
- Tap a square, then a digit. Notes lets you pencil in small digits. A few starter digits may be filled in for you.
- Each puzzle has exactly one answer.
Tip: some totals only work one way. Two squares that make 3 must be 1 and 2; two squares that make 17 must be 8 and 9.
