Cave (Inside+Outside) (1130)
Instruction:
Shade some cells to leave behind a single orthogonally-connected group—the cave— with no shaded cells enclosed within the cave. In other words, all shaded cells must be connected edge-wise by other shaded cells to an edge of the grid.
Each number inside the cave indicates the total count of unshaded cells connected in line vertically and horizontally to the numbered cell including the cell itself.
Each number outside the cave indicates the total count of shaded cells connected in line vertically and horizontally to the numbered cell including the cell itself.
