A foul (scored by an F on some computer scoring systems) refers to a ball that first rolls into the gutter and then strikes deadwood (felled pins resting in the gutter) or hops out of the gutter and strikes a standing pin, a "lob"-bed ball that touches neither the approach, nor lane in the three meters' distance of lanebed before the lob line, or as in tenpins and duckpins, a roll made by a bowler's foot crossing over the foot foul line shared by nearly all bowling sports. Special scoring comes into play.
