Sure! Here's an example of a simple Snake game implemented as a single HTML file in JavaScript:

You can save this code in a file with a .html extension and open it in your smartphone's web browser to play the Snake game. The game board will be displayed as a 20x20 grid, and you can control the snake's direction using the keyboard arrows. The game loop updates the game state every 200 milliseconds, making the snake move and checking for collisions with the walls, itself, and the food. Enjoy playing!
