Rules: Shade some cells in the grid, so that no two shaded cells are orthogonally adjacent and the unshaded cells form a single orthogonally connected group. Cells with clues can be shaded: if a clue cell is unshaded, it must give the number of shaded cells in that direction, but if a clue cell is shaded, it might or might not be correct.
