Kakuro: what to know before playing
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. Check the relevant rule before repeating a move. Check the rule that explains your first action. 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.
Take a closer look while playing
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Keep the objective visible.
The goal to keep in mind
Complete a 4×4 sum grid with digits 1–9, no repeats in any row or column, and the displayed totals. Keep that objective in view throughout the round. Try to explain the aim in your own words.
The order of play
- 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. Check any mode label before starting.
A useful example
A row total 18 with fixed values 2, 4 and 7 requires 5 in the remaining cell. Your next round may have a different position, so inspect it before acting. Choose a deliberate next step.
A mistake to avoid
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. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
