The rules are simple. Keep the ball bouncing inside the circle.
WARNING : EXTREMELY ADDICTIVE!!
Your goal is to keep the ball bouncing inside the circle. All you need is one paddle and your reflexes. You can control only the direction of paddle movement just by tapping the screen. The rules are simple but still demanding.
Be careful not to become addicted. You have been warned.
In short this game can be described as mix of ping pong and squash.
