An introduction to playing Kakuro

Kakuro gives you a focused activity to play in your browser. Complete a 4×4 sum grid with digits 1–9, no repeats in any row or column, and the displayed totals. Use the example below to understand a decision. Check the rule that explains your first action. Look at what changes after your first action.

Practise sums on twelve small, unblocked 4×4 grids. These teaching boards use whole-row and whole-column totals rather than the blocked runs of classic Kakuro.

Build familiarity through play

After a move, check what changed. Decide which rule explains the new state before acting again. Keep the objective visible.

Understand the aim

Complete a 4×4 sum grid with digits 1–9, no repeats in any row or column, and the displayed totals. An attractive position is not enough unless the goal is met. Take a moment to understand the current position.

How a round unfolds

  1. Compare a row total with its fixed entries.
  2. Use the column total for the same blank.
  3. Enter digits 1–9.
  4. Check puzzle verifies totals and non-repetition.

The controls to know

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Keep the playing area visible while using these controls. Make sure you are interacting with the game rather than the surrounding page.

See the idea in action

A row total 18 with fixed values 2, 4 and 7 requires 5 in the remaining cell. Apply the same reasoning to the position in your own round. Look for the relevant detail.

Keep this in mind

Repeated digits in a run are forbidden even when the sum matches. Read the feedback to see why an action did not have the expected result. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
