Sure! Here's an example of a simple billiards game implemented as a single HTML file using JavaScript and pictograms:
In this game, a cue ball (represented by the pictogram of a white ball) moves around the canvas. The ball changes direction when it reaches the edges of the canvas, simulating billiards' ball bouncing behavior.
To play the game, you can open the HTML file in a web browser on your smartphone and observe the movement of the cue ball within the boundaries of the canvas.
