Use the mouse to move your paddle up and down. Your paddle is the green one on the left. Angle your shots just right to get the paddle on the right to miss. The only way to get to the next level is to get four balls past your opponent - you lose if you miss four balls. There are bonus blocks that pop up in the screen that give you extra points if you're able to hit the ball into them. Just like the game says, you wouldn't be wrong if you said this game is like Pong! Each level gives you extra challenges. You won't want to stop trying to beat your highest score with Po- I mean, Ping!
