Nurisquare
Shade square blocks so every white region has exactly one size clue.
Controls
Shade cells so every orthogonally connected group of shaded cells forms a solid square. The remaining white cells split into regions; each white region contains exactly one number equal to its area. Tap a cell to cycle empty → black → white; use Clear to reset and the answer button to reveal or hide the full solution.
