Sure! Here's an example of a simple game that you can play against an AI opponent on a smartphone using pictograms. Remember to save it as a single HTML file and enclose it within script tags.
Rock Paper Scissors Game
In this game, when you click on one of the pictogram choices (rock, paper, or scissors), the AI will randomly select one as well. The game will determine the winner based on the usual rock-paper-scissors mechanics, and display the result in an alert message.
