Chrome 7.0.517.41 on a Mac. I got a score of 9135 (I stopped when it exceeded 9000). http://img201.imageshack.us/img201/8486/screenshot20101102at305.png http://img201.imageshack.us/img201/8486/screenshot20101102at... Method: Get the ball to hit a paddle on the top or bottom. It seems the code that deals with paddle collisions only imagines horizontal collisions, so, every frame (or whatever unit of time it uses), it registers a collision and reverses its horizontal direction. This is the "sticks to the paddle, vibrates, and travels up the paddle" behavior you describe. Move the paddle up and down to follow the ball's vertical movement, so it doesn't fall off. You rack up a lot of collisions very quickly like this. This works much better on the left side, for whatever reason. I've succeeded twice in getting the ball to vibrate on the paddle while moving slow enough vertically that I can follow it and prevent it falling off. I haven't managed to do it on the right side; I have gotten it to vibrate, but only for a short time before it gets flung away. Also, sometimes the ball vibrates on the top or bottom surface for a little while (fraction of a second). This has happened only on the left side so far.
