Instruction:
Shade some empty cells to create a single connected group. Cells with numbers cannot be shaded, and the shaded cells cannot form a 2×2 square anywhere in the grid. Each numbered cell indicates the total number of shaded cells connected vertically and horizontally to that numbered cell, in a straight line till the next numbered/unoccupied cell, or the edge of the grid.
