Sure! Here's an example of an auto Atari Pong game implemented as a single HTML file using JavaScript:
This code will create a canvas element and render a ball and a paddle on it. The ball will move automatically and bounce off the walls and paddles. You can control the paddles' movement by modifying the `paddle.dy` variable.
Please note that this is just a basic implementation of the Atari Pong game. You can further customize and enhance it to fit your requirements.
