Elastic rope games, Wow, a chineese jump rope is what we knew them as. They started with two people putting them around their anckles and standing far apart, the third person would jump in a certain way, like this.
They would jump(In, Out, etc.)of the rope and say out loud at the same time;

In
Out
Side
Side
Step
In
Out

The next set was you had to click your feet each time together and do it again.
Next was spin around and so on, I'm sure you get the idea.
I Loved that game.
