A practical guide to Kakuro
Make Kakuro your next activity in the game library. 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.
Practice beyond the first move
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Use the example to check your reasoning.
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. Use the instructions to see which actions move you towards it. Keep the controls in easy reach.
How to proceed
- 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.
Getting comfortable with the controls
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Use the control method described here for this activity. Use the visible help when you are unsure of the next input.
Follow the example
A row total 18 with fixed values 2, 4 and 7 requires 5 in the remaining cell. Use the example as a guide rather than a substitute for reading your board. Consider the next action carefully.
Keep this in mind
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.
