A Nikoli puzzle type featuring a grid with circled numbers in some cells. The clues have the same meaning as in corral, each indicating the total number of squares, including itself, that you can see looking in the orthogonal directions up to the edge of the grid or the first wall. In this case, the walls are isolated black cells which cannot touch orthogonally. The white cells must remain a single orthogonally connected group.
