You have your cup upside down. So first, you're gonna clap your hand's two times to start. Then you bank the cup three times and clap one time again. See the video on next page.
After that, you're gonna lift the cup and like move the cup to the side (but I didn't move that to the side cause I played alone). And then you're gonna clap one time. Video next page.
So now you know how to play the cup game!
