How to play Kakuro

Use a short break to learn the rhythm of Kakuro. 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. Make your first input carefully and watch the result. Use the example below to understand a decision.

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.

Notice the feedback

Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Refer to the controls when needed.

Your goal

Complete a 4×4 sum grid with digits 1–9, no repeats in any row or column, and the displayed totals. The feedback beside the game helps you follow the round. Start with a deliberate move.

Step by step

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.

Controls

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Read a button’s label before selecting it. Use the visible help when you are unsure of the next input.

A useful example

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.

Watch out for this

Repeated digits in a run are forbidden even when the sum matches. Take a moment to reassess the position before continuing. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
