Sure! Here's an example of a simple basketball game implemented as a single HTML file using JavaScript. It includes realistic basketball physics and can be played on a smartphone. The game uses pictograms to represent the basketball and the hoop.
To play the game, you can copy the above code into a new HTML file (e.g., `basketball_game.html`), save it, and open it in a web browser on your smartphone. You can drag the basketball (represented by a pictogram) to aim and release it to shoot. The goal is to throw the basketball into the hoop (also represented by a pictogram) as many times as possible before the ball hits the ground. The score is displayed, and the game is over when the ball hits the ground.
