Sure, here's an example of an auto Atari Pong game with lasers and 12 balls implemented as a single HTML file using JavaScript:
This code will create an Atari Pong game on an HTML canvas with paddle, multiple balls, and laser-like movements for the paddles. The game will automatically play itself with the computer-controlled paddle adjusting its position based on the ball's movement. The balls will bounce off the paddles and the top/bottom walls. The game will continue until all the balls go out of bounds.
