When I was a kid in France we used to play “elastique” which is the same as Chinese Jump Rope, but there weren’t any set patterns to jump. Part of the game was that you made up your own pattern, after agreeing on a certain level of difficulty, like there had to be some point in it where you jumped on the line. So you couldn’t really get out on ankles, but then you had to repeat the pattern at knees etc. If you changed anything, you lost your turn. So it was partly a memory thing.
