A practical guide to Kakuro

Something to practise

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

What the game asks you to do

Complete a 4×4 sum grid with digits 1–9, no repeats in any row or column, and the displayed totals. Use the instructions to see which actions move you towards it. Check the rules when you are unsure.

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.

Getting comfortable with the 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. A new-round button replaces the current round.

Try this 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.

A useful caution

Repeated digits in a run are forbidden even when the sum matches. Compare the situation with the worked example. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
