Kakuro: rules and examples
Take a moment with Kakuro before moving to another game. 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. 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.

Your goal
Complete a 4×4 sum grid with digits 1–9, no repeats in any row or column, and the displayed totals. Use the instructions to see which actions move you towards it. Return to the instructions when a step is unclear.

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. Use the control method described here for this activity. Return to the rules if the result is unexpected.
A closer look at one example
A row total 18 with fixed values 2, 4 and 7 requires 5 in the remaining cell. Use the example as a guide rather than a substitute for reading your board. Read the matching step again.
An important reminder
Repeated digits in a run are forbidden even when the sum matches. Check the rule before repeating the action. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
