Sure! Here's an example of a simple Snake Game implemented as a single HTML file using JavaScript. It includes pictograms and is designed for smartphone operation:

Snake Game

This code will create a Snake Game where the player controls the snake using the arrow keys on their smartphone. The snake must collect apples while avoiding hitting itself or the game board boundaries. The player's score is the length of the snake. If the snake hits itself or goes out of bounds, the game ends and the player is presented with a final score. They can then restart the game by clicking "Ok" on the alert box.
