Jump rope (American English) or skipping rope (British English) is the primary tool used in the game of skipping played by children and many young adults, where one or more participants jump over a rope swung so that it passes under their feet and over their heads. This may consist of one participant turning and jumping the rope, or a minimum of three participants taking turns, two of whom turn the rope while one or more jumps. This is called long rope. Sometimes the latter is played with two turning ropes; this form of the activity is called Double Dutch and is significantly more difficult. Jump-rope rhymes are often chanted beginning when the skipper jumps in and ending when the skipper is tripped up.
