Kakuro: how a round works
Start Kakuro by looking at the playing area and its controls. Complete a 4×4 sum grid with digits 1–9, no repeats in any row or column, and the displayed totals. Keep the game area visible while you use its controls. 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.
One thing to notice as you play
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Make the next step deliberately.
The purpose of your moves
Complete a 4×4 sum grid with digits 1–9, no repeats in any row or column, and the displayed totals. Read that aim before choosing your first action. Take a moment to understand the current position.
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 to interact with the game
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.
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. Look for the relevant detail.
An important reminder
Repeated digits in a run are forbidden even when the sum matches. Take a moment to reassess the position before continuing. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
