Kakuro: what to know before playing
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. Keep the game area visible while you use its controls. 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.
Practice beyond the first move
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. Refer to the controls when needed.
What you are aiming for
Complete a 4×4 sum grid with digits 1–9, no repeats in any row or column, and the displayed totals. The feedback beside the game helps you follow the round. Return to the instructions when a step is unclear.
Work through the instructions
- 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. Read a button’s label before selecting it. Read the example below alongside these instructions.
A closer look at one example
A row total 18 with fixed values 2, 4 and 7 requires 5 in the remaining cell. Compare this with the rule that governs the move. Verify the rule before continuing.
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.
