Kakuro: what to know before playing
Choose a round of Kakuro and settle into its rules. 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. 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.

Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Use the example to check your reasoning.
The objective of a round
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. Review the board or playing area as it changes.
How a round unfolds
- Compare a row total with its fixed entries.
- Use the column total for the same blank.
- Enter digits 1–9.
- Check puzzle verifies totals and non-repetition.
How to use 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. Keep the playing area visible while using these controls. Read the example below alongside these instructions.
One way to understand the rules
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. Notice the change in the playing area.
Notice this detail
Repeated digits in a run are forbidden even when the sum matches. Take a moment to reassess the position before continuing. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
