Jump rope, also known as skipping rope or skip rope, is a game played primarily by children and primarily by girls in which one or more children jump over a spinning rope so that it passes under their feet and over their heads. This may consist of one child twirling and jumping the rope, or at least three children taking turns, two of which twirl the rope while one jumps. If the latter is played with two twirling ropes, it is called Double dutch, and is significantly more difficult.
