Mirror Mosaic
One half of this glass window is lit. Tap cells on the dark side so the whole window is a perfect mirror across the glowing seam — then fold it to check.
🎯 Every lit tile lands exactly on its mirror partner: same distance from the seam, same row (or column). No extras.
✓ Solved!
Line symmetry: a shape is symmetric about a line if folding along that line lands every part exactly on top of a matching part. Each glowing tile needs a twin the same number of squares on the other side of the seam. Tap a cell to light it; tap it again to clear it.
