Sure! Here's a simple implementation of a billiards game that you can play on a smartphone using HTML, JavaScript, and pictograms. Just copy the code below and save it as a single HTML file.
This code sets up a simple billiards game on a canvas element. It initializes the game and sets up the game loop. You can add your own game logic to the `update()` function and draw your own graphics in the `draw()` function. The touch events are also included, which you can use to handle player interaction on a smartphone.
Please note that this basic implementation only includes a green table, a yellow cue ball, and a red ball as examples. You can modify and enhance the game to suit your needs. Let me know if you have any other questions.
