Your goal
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. The example below illustrates a decision.
Step by step
- 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.
Controls
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. Return to the rules if the result is unexpected.
A useful example
A row total 18 with fixed values 2, 4 and 7 requires 5 in the remaining cell. Your next round may have a different position, so inspect it before acting. Keep the controls nearby.
Watch out for this
Repeated digits in a run are forbidden even when the sum matches. Take a moment to reassess the position before continuing. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
