The goal to keep in mind
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. Follow this game’s rules rather than another version’s.
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.
Choosing and moving on screen
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. Use the example as a guide rather than a substitute for reading your board. Keep the game’s format in mind.
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. After a move, check what changed. Decide which rule explains the new state before acting again.
