How to play Kakuro
Kakuro is a number crossword. Each run of white cells adds up to its clue, and no digit repeats in a run.
Controls: Tap or click a cell, then a number on the pad (or type 1–9; 0 or Backspace clears). Arrow keys move between cells. H gives a hint, which costs points.
Tips
- Some sums have only one set of digits: 3 in two cells is always 1 + 2, 4 is 1 + 3, 16 is 7 + 9 and 17 is 8 + 9. Start there.
- Where an across run and a down run cross, the digit must belong to both. That often leaves only one choice.
- Long runs with big sums leave out only the small digits. 45 in nine cells uses every digit once.
- Runs turn red when a digit repeats or the sum is wrong, so mistakes show at once.
- Hints fill a cell for you but cost points. Use them only when you're stuck.
