Kakuro

Number-crossword — fill each run so it adds up to its clue.

How to play

  1. Fill every white cell with a digit from 1 to 9.
  2. 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.
  3. Every run must total its clue — and a digit can appear only once within a run.

Controls

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.
