Sure! Here's an example of a simple billiards game implemented in a single HTML file using JavaScript and pictograms for a smartphone operation:

Score: 0

Swipe on the canvas to aim and shoot.

This HTML file contains a canvas element where the billiards game is displayed. The player can aim and shoot by swiping on the canvas. The cue ball's movement is based on the angle and speed set by the player's swipe. The goal is to pocket the cue ball into the pockets displayed on the canvas. Each successful pocketing increases the player's score. Note: This is a basic implementation and can be expanded upon to add more features and interactions.
