Sure! Here's an example of a simple Tetris game implemented as a single HTML file using JavaScript and pictograms for smartphone operation:

This HTML file contains the JavaScript code for a basic Tetris game. To play the game, open this file in a web browser and use the arrow keys on your smartphone keyboard or on-screen controls to move and rotate the falling Tetromino pieces. The goal is to fill complete rows by arranging the Tetrominos without gaps. When a row is completed, it will be cleared, and the player earns points. The game ends when the pieces stack up to the top of the screen.
