The pins shall not be reset. The player will forfeit all pins downed by the foul ball or balls and score only those downed by the balls that were fair. If no pins are left standing by the foul action of the second ball, the player shall score only the pins downed by the first ball. Bonus balls rolled in the gutter on a strike or a spare. Both bonus balls foul, score zero for bonus.
First ball is foul, bowler scores zero for bonus.
Rolling extra balls in any frame will constitute a foul. Penalty of a zero for frame. All downed pins, called wood, remaining on the lane entirely behind the deadwood line are live and playable. Wood shall be judged live or dead only after it has stopped moving. Any questionable deadwood shall be removed by a designated official.
