It is fun like real juggling and you need the same timing as real world juggling.
The game is to juggle the balls on the screen by tapping balls. Ball will bounce to other side when it is hit by tapping with your finger.
When tapping alternates, as like right tapping, let tapping, right tapping, and so on, the juggling count will increase. When the juggling count reaches to 50 times, you will get another ball to juggle. If you reach another 50 times, you will get one more ball.
The game is very intuitive. Just try and improve the sense of juggling.
