Sure! Here's an example of a simple Pong game written in a single HTML file, using JavaScript and embedded within script tags. The game is playable on a smartphone and uses swipe gestures to move the player's stick, while the opponent's stick is controlled by AI. The score is displayed on top of the game using pictograms.

0 - 0

Save this code into an HTML file and open it in a web browser on your smartphone to play the Pong game. Swipe left to right or right to left to move your stick and try to score against the AI opponent. The score is displayed on top of the game using pictograms (numbers). Enjoy playing!
