How to Play Kakuro

THE PLAYBOOK · COEYSHOES

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. Check the relevant rule before repeating a move. Identify the playing area and the controls you need. 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.

Bring this focus to a round

Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Refer to the controls when needed.

What counts as success

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. Start with a deliberate move.

A walkthrough of the rules

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. On a smaller screen, keep the active part of the board within view. Contact us with the game and device if a control does not respond.

See how the rules apply

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.

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. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
