Grid Shading

How to Play

1. Click cells to shade them black (borders between rectangles)
2. White cells must form rectangular regions
3. Each rectangle must contain exactly one number
4. The number shows the area (cell count) of that rectangle
5. No 2×2 area can be entirely black

Example

A cell with 6 means it belongs to a 6-cell rectangle (e.g., 2×3 or 1×6). A cell with 1 means it's a single-cell rectangle completely surrounded by black.
