Read before your next round of Kakuro
Bring your attention to one round of Kakuro. Complete a 4×4 sum grid with digits 1–9, no repeats in any row or column, and the displayed totals. Look at what changes after your first action. Check the rule that explains your first action. Use the example below to understand a decision.
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.

After a move, check what changed. Decide which rule explains the new state before acting again. Use the example to check your reasoning.
What the game asks you to do
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. Take a moment to understand the current position.

- Check puzzle verifies totals and non-repetition.
Your inputs
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Keep the playing area visible while using these controls. Avoid pressing the same control repeatedly while a move is being processed.
Work through an example
A row total 18 with fixed values 2, 4 and 7 requires 5 in the remaining cell. Your next round may have a different position, so inspect it before acting. Check the stated objective.
Pay attention to this rule
Repeated digits in a run are forbidden even when the sum matches. A different version of the game may use a different rule. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
