Kakuro: rules and examples
Open Kakuro, check the instructions and begin a round. 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. Check the rule that explains your first action. Look at what changes after your first action.
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.
An idea for your next attempt
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.
Aim for this result
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. Check the rules when you are unsure.
A walkthrough of the rules
- 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.
How your actions work
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Keep the playing area visible while using these controls. Use one clear input at a time.
See how the rules apply
A row total 18 with fixed values 2, 4 and 7 requires 5 in the remaining cell. Apply the same reasoning to the position in your own round. Look for the relevant detail.
Watch out for this
Repeated digits in a run are forbidden even when the sum matches. Compare the situation with the worked example. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
