Know the goal in Kakuro

Make Kakuro your next activity in the game library. Complete a 4×4 sum grid with digits 1–9, no repeats in any row or column, and the displayed totals. Look at what changes after your first action. Check the rule that explains your first action. 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 beyond the first move

Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Keep the objective visible.

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. Use the instructions to see which actions move you towards it. Take a moment to understand the current position.

Step by step

  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.

Making selections and moves

Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Use the control method described here for this activity. Contact us with the game and device if a control does not respond.

An example before you play

A row total 18 with fixed values 2, 4 and 7 requires 5 in the remaining cell. Compare this with the rule that governs the move. Look for the relevant detail.

Pay attention to this rule

Repeated digits in a run are forbidden even when the sum matches. Check the rule before repeating the action. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
