How to play 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. Choose a comfortable screen position before beginning. 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.
Try a deliberate move
After a move, check what changed. Decide which rule explains the new state before acting again. Use the example to check your reasoning.
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. Review the board or playing area as it changes.
Step by step
- 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.
Controls
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. Avoid pressing the same control repeatedly while a move is being processed.
A useful example
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. Verify the rule before continuing.
Watch out for this
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. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
