This is how I used to play it.

Two people stand facing each other with their hands out. Both their right hands are on the top and left is on the bottem. They move their hands up and down clapping 3 times in between. They are chanting

"Concentration.64. No mistakes. Or hesitations. I'll go first. and you go second. The topic is --make up a topic--." Keep going on with the topic until someone messes up. The other person wins.


P.S. In the quotes, when you see a period(.) that is where you clap three times.
