Kakuro
Number-crossword — fill each run so it adds up to its clue.
How to play
- Fill every white cell with a digit from 1 to 9.
- A clue sits on a dark cell: the top-right number is the sum of the run to its right; the bottom-left number is the sum of the run below.
- Every run must total its clue — and a digit can appear only once within a run.
Controls
- Tap a white cell, then tap a digit (1–9) to fill it; erase to clear.
Example
4→ 1 3
An across clue “4” means its run sums to 4 — here 1 + 3, all digits distinct.
Tip · Short runs with extreme sums have only one combination — a 2-cell run summing to 3 must be 1+2. Pin those first.
