Cross out numbers so each row and column sums to its target. 0:00

Click cycles: unmarked → keep → cross out → clear 7 7 7

How It Works

Cross out the extras

Every row and column has a target sum shown outside the grid. Cross out numbers inside so the remaining values add up to the target on every row and every column.

Click a cell once to mark it as a keeper (circled). Click again to cross it out. A third click clears it back to unmarked.

The live "current / target" readout next to each total tells you where you stand. When every row and column glows green, you've solved it.
