Kakuro: what to know before playing
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. 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.
A small practice goal
After a move, check what changed. Decide which rule explains the new state before acting again. Refer to the controls when needed.
Understand the aim
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. Check the rules when you are unsure.
The order of 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.
Keyboard and screen controls
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. Contact us with the game and device if a control does not respond.
See the idea in action
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. Look for the relevant detail.
Avoid this misunderstanding
Repeated digits in a run are forbidden even when the sum matches. Check the rule before repeating the action. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
