Sure! Here's an example of a simple billiards game implemented in a single HTML file, using JavaScript and pictograms:
Billiards Game
In this game, a red ball represents the billiard ball. The ball moves inside a canvas element and bounces off the walls when it reaches the edges. The game is automatically started when the webpage loads, and the ball's position is updated every 10 milliseconds.
Please note that this is a very basic implementation and does not include advanced features like player input, collision detection between balls, or scoring. Feel free to enhance and modify it according to your requirements.
