Sure! Here's a simplified version of a billiards game that can be played on a smartphone. Just save the following code as a single HTML file and open it in a browser to start playing:
In this game, there are several balls represented by red circles. They move randomly within the canvas, bouncing off the boundaries. The game continuously redraws the balls to create an animation effect using the `moveBalls` function.
Feel free to add more features and customize the game as per your preferences.
