An introduction to playing Kakuro

Choose a round of Kakuro and settle into its rules. Complete a 4×4 sum grid with digits 1–9, no repeats in any row or column, and the displayed totals. Choose a clear next step rather than rushing through the instructions. Check the rule that explains your first action. 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.

What you need to achieve

How to interact with the game

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. A careful first action helps you become familiar with the layout. Make sure you are interacting with the game rather than the surrounding page.

A useful example

A row total 18 with fixed values 2, 4 and 7 requires 5 in the remaining cell. Focus on why the action is allowed, not only its outcome. Look for the relevant detail.

Check this before moving on

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. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
