       Shade some cells so that each orthogonally connected area of shaded cells is in the shape of a rectangle. The shaded rectangles must all form a single loop through diagonal connections, with no branches. All cells with circles must be shaded, and if a circle contains a number, its shaded rectangle must contain the indicated number of cells. Solve online

       Shade some cells so that all areas of orthogonally connected unshaded cells are rectangular and all areas of orthogonally connected shaded cells are not rectangular. The unshaded rectangles must all form a single loop through diagonal connections, with no branches. Clues cannot be shaded, and represent the number of cells in the unshaded area they belong to. An unshaded area of cells cannot contain more than one clue. No 2x2 region may be entirely shaded.      In this puzzle, a question mark can represent any positive integer. Solve online
