Sure! Here's an example of a basic billiards game implemented as a single HTML file using JavaScript and pictograms:
In the above code, the game canvas is displayed with two pictograms: a cue ball and a cue stick. The cue stick can be moved using the smartphone touchscreen to aim at the cue ball. However, this code is just a basic structure to get you started. You can enhance it with game logic, rules, and multiplayer functionality depending on your requirements.
Note: For the code to work properly, you would need to have the `emozi_all/ball.png` and `emozi_apple.png` images available in the same directory as the HTML file for the pictograms to show up correctly.
