Hey, I'm Asian and yes, I did play Chinese jumprope (called Chinese garter, since that was what we used instead of rubber bands) in my grade school years... I remember pestering my mom for shoes without buckles so I could get past the tricky bits...

Chinese jumprope - in, out, step on, in out, twist, out, twist, out, diamond, out, diamond, out.

Japanese jumprope - i know we called it japanese, but i have no idea what made it so japanese...all we did was jump over a rope (going progressively higher as the game goes one...the really good players were the ones who could cartwheel over the highest part)

There was another variation called 'triangle', but i can't remember the rules anymore.

Hope this helps! cleod
