Sure, I can create a game for you using JavaScript and HTML. Here's an example of a simple rock-paper-scissors game that can be played on a smartphone. The game uses emoji icons as pictograms.
Rock Paper Scissors
To run the game, copy the above code into a file with a `.html` extension (e.g., `game.html`). You can then open the HTML file in a web browser on your smartphone or computer, and the rock-paper-scissors game will be playable. Simply click on one of the emoji icons to make your choice and see the result. The game will display the user and computer choices, as well as the winner or a tie. Enjoy playing!
