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. 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.
Give this approach a try
After a move, check what changed. Decide which rule explains the new state before acting again. Make the next step deliberately.
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. Try to explain the aim in your own words.
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. A careful first action helps you become familiar with the layout. Use the visible help when you are unsure of the next input.
Try this 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. Consider the next action carefully.
A common point of confusion
Repeated digits in a run are forbidden even when the sum matches. Read the feedback to see why an action did not have the expected result. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
