TRIM
Every number counts + by default. Turn exactly one per row and per column − (red) so each line's signed sum hits its target.
How to play
- Every number starts + added. Tap it to toggle to − subtract, and tap again to switch back.
- Solve by turning exactly one number per row and column red (−), leaving the rest added.
- Each target shows its goal and turns green when the line's sum matches it, amber when the sum is too high, and red when it's too low.
- Every daily puzzle has exactly one solution — pure deduction.
