How to play Kakuro
Take a moment with Kakuro before moving to another game. 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. Make your first input carefully and watch the result. Choose a clear next step rather than rushing through the instructions.
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.
Focus on one rule
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. 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. Keep that objective in view throughout the round. 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. Use the control method described here for this activity. Read the example below alongside these instructions.
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. Keep the controls nearby.
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. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
