Sure! Here's an example of a simple billiards game implemented as a single HTML file, using JavaScript and pictograms:
In this implementation, we have a canvas element where the game is drawn. The ball's position and velocity are updated in the `update` function, which is called repeatedly using `requestAnimationFrame`. The ball bounces off the walls of the canvas, and its position is updated accordingly. The ball is drawn as a blue circle on the canvas.
You can play this game on a smartphone by opening the HTML file in a web browser that supports JavaScript. By touching or clicking the screen, you can control the ball's movement indirectly by changing its initial position or velocity based on user interaction.
Please note that this is a minimal example and does not include advanced game mechanics or additional features typically found in a billiards game.
