Sure! Here's a game of Tetris implemented as a single HTML file with JavaScript. You can play it on a smartphone and it uses pictograms for the gameplay elements.

Save this code in a file with the ".html" extension (e.g., `tetris.html`), then you can open it in any web browser to play the Tetris game.
