Kakuro: learn through an example
Open Kakuro, check the instructions and begin a round. Complete a 4×4 sum grid with digits 1–9, no repeats in any row or column, and the displayed totals. Choose a clear next step rather than rushing through the instructions. 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.

See the idea in action
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. Consider the next action carefully.
Notice this detail
Repeated digits in a run are forbidden even when the sum matches. Compare the situation with the worked example. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
