How to play Kakuro
Kakuro gives you a focused activity to play in your browser. Complete a 4×4 sum grid with digits 1–9, no repeats in any row or column, and the displayed totals. Look at what changes after your first action. Identify the playing area and the controls you need. 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.
Build a steady rhythm
Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round. Notice the feedback after each input.
Your goal
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. The example below illustrates a decision.
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. On a smaller screen, keep the active part of the board within view. Return to the rules if the result is unexpected.
A useful example
A row total 18 with fixed values 2, 4 and 7 requires 5 in the remaining cell. Focus on why the action is allowed, not only its outcome. Choose a deliberate next step.
Watch out for this
Repeated digits in a run are forbidden even when the sum matches. Take a moment to reassess the position before continuing. After a move, check what changed. Decide which rule explains the new state before acting again.
