This is endless ping pong single - player game. The ball will bounce to random places. You need to catch it with the paddle every time it's going to fall. If you can't catch it, it will touch the light pink line at the bottom. Every time catch and bounce it, it gives you a bounce point. Every time you cannot catch the ball and it touches the line, you will have to restart the game and you will lose your score.
I got it from a Scratch Team tutorial, thank you Scratch Team! And the number counter from Griffpatch!
