How to Play Kakuro

THE PLAYBOOK · LAIDIANTUAN

Bring your attention to one round of Kakuro. Complete a 4×4 sum grid with digits 1–9, no repeats in any row or column, and the displayed totals. Check the relevant rule before repeating a move. Use the opening round to become familiar with the layout. 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.

Focus on one rule

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

Your goal

Complete a 4×4 sum grid with digits 1–9, no repeats in any row or column, and the displayed totals. Keep that objective in view throughout the round. Take a moment to understand the current position.

Step by step

Compare a row total with its fixed entries.
Use the column total for the same blank.
Enter digits 1–9.
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. Check any mode label before starting.

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. Take a moment to compare.

Watch out for this

Repeated digits in a run are forbidden even when the sum matches. Check the rule before repeating the action. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
