Kakuro: instructions and practice
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. Choose a clear next step rather than rushing through the instructions. Check the rule that explains your first action. Check the relevant rule before repeating a move.
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.
An idea for your next attempt
After a move, check what changed. Decide which rule explains the new state before acting again. Refer to the controls when needed.

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. On a smaller screen, keep the active part of the board within view. Use one clear input at a time.
Try this example
A row total 18 with fixed values 2, 4 and 7 requires 5 in the remaining cell. Apply the same reasoning to the position in your own round. Choose a deliberate next step.
A common point of confusion
Repeated digits in a run are forbidden even when the sum matches. A different version of the game may use a different rule. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
