Kakuro: instructions and practice
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. Check the relevant rule before repeating a move. 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.
Practice with a purpose
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. Notice the feedback after each input.
The challenge in front of you
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. Keep the controls in easy reach.
From the start of a round
- 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.
The controls to know
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. On a smaller screen, keep the active part of the board within view. A new-round button replaces the current round.
Try this example
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. Take a moment to compare.
Watch out for this
Repeated digits in a run are forbidden even when the sum matches. A different version of the game may use a different rule. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
