Kakuro: rules and examples
Read the aim of Kakuro, then make your first move. 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. 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.
A small practice goal
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. 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. The feedback beside the game helps you follow the round. Keep the controls in easy reach.
Start here and follow along
- 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. Read a button’s label before selecting it. Avoid pressing the same control repeatedly while a move is being processed.
Follow the 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. Choose a deliberate next step.
An important reminder
Repeated digits in a run are forbidden even when the sum matches. Compare the situation with the worked example. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
