 Rules:   Shade some cells so that all shaded cells form one orthogonally connected area. No 2x2 region may be entirely shaded. Clues outside the grid represent the lengths of the blocks of consecutive shaded cells in the corresponding row or column, in order. A question mark represents one block of an unknown number of cells. An asterisk represents any number of blocks of shaded cells, including none at all. Solve it online

 Rules:   Shade some tetrominoes of cells such that no two tetrominoes touch each other orthogonally, but all tetrominoes form one diagonally connected network. Two tetrominoes of the same shape may not touch diagonally, counting rotations and reflections as the same. Clues cannot be shaded, and represent the number of shaded cells in a straight line in the indicated direction. Solve it online
