Kakuro: how a round works
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. 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 beyond the first move
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Make the next step deliberately.
Your goal
Complete a 4×4 sum grid with digits 1–9, no repeats in any row or column, and the displayed totals. An attractive position is not enough unless the goal is met. Review the board or playing area as it changes.
The steps to play
- 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.
How to interact with the game
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. A careful first action helps you become familiar with the layout. Read the example below alongside these instructions.

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. Take a moment to compare.
Where a round can go wrong
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.
