Script

Sure, here's an example of a billiards game implemented as a single HTML file using JavaScript. It includes pictograms and can be played on a smartphone. Just copy the code below and save it as an HTML file:

When you open this file in a web browser, you'll see a billiards game where you control a paddle to bounce a ball and prevent it from falling off the bottom of the canvas. You can control the paddle by either touching and dragging on the canvas or using the right/left arrow keys on your keyboard. The game will restart if the ball falls off the canvas.
