Script

Sure, here's a simple implementation of Tetris as a single HTML file using JavaScript and enclosed in script tags. The game can be played on a smartphone and includes pictograms for better visualization.

This implementation provides a basic version of Tetris where you can control the falling pieces using the left, right, and down arrow keys. The game ends when a piece reaches the top of the grid. You can further enhance the game by adding levels, score, audio, and other features as per your requirements.
