Kakuro: how a round works
Start Kakuro by looking at the playing area and its controls. 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. 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.
Give this approach a try
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Refer to the controls when needed.

Getting comfortable with the 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. A new-round button replaces the current round.
See how the rules apply
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. Take a moment to compare.
A common point of confusion
Repeated digits in a run are forbidden even when the sum matches. Take a moment to reassess the position before continuing. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
