Sure! Here's an example of a simple billiards game that you can play on a smartphone using pictograms:
To play the game, you can click/tap and drag the white cue ball (represented by a circle) around the canvas. This implementation provides a basic framework for a billiards game, including a way to interact with the cue ball.
Note that this is a very simplified version and does not include the full rules or physics of billiards. You can extend it further by adding billiard balls, collision detection, and other game mechanics.
