Fill cells to match the numbers. Each number is a run of filled cells in that row or column, in order, with at least one gap between runs. Tap to fill, hold the strip (or long-press, or right-click) to mark an X. Drag to paint a line. Numbers cross themselves out when their run is certain, and turn red when a line can no longer be finished. Wrong moves are allowed; the puzzle is solved when the picture is right.
