How to Play Kakuro

THE PLAYBOOK · HRZBANJIA

Learn the rules of 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. Keep the instructions close while learning this activity. Check the relevant rule before repeating a move.

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.

Practice with a purpose

Read one step at a time and try it on the playing area. Match the instruction to the control you use. Notice the feedback after each input.

Your goal

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. Keep the controls in easy reach.

From the start of a round

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.

Keyboard and screen controls

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. Use one clear input at a time.

A closer look at one 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.

Notice this detail

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. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
