Hitori #840

#840 · Oct 20MediumArchive: not ranked

How to play

Shade squares until no digit appears twice in any row or column among the white squares.
Shaded squares never touch side by side (corners are fine), and all the white squares must stay joined in one group, side by side.
Tap a square to shade it, again to circle it (your note for “this one stays white”), again to clear it. Drag across squares to paint several at once.
Easy grids are 5 × 5, medium 7 × 7 and hard 9 × 9. Every grid has exactly one answer, found by reasoning alone. Fastest time wins; fewer changes break ties.
