You have to hit a ball using the black square.
If the ball hits the top you will get 1 point, if the ball hits the circle in den middle of the top you will get 5 points!
But if the ball hits the bottom the game will be over and your score and highscore will appear.
Unfortunately the name of the app on your iPhone is "Ping Pong" instead of "Flip-Ball" but anyway I hope that you will enjoy my app and write a good review.
