Sure, here's a simple implementation of the Snake Game using HTML, JavaScript, and pictograms for smartphone operation:
Game Over!
This implementation creates a game board using HTML and CSS, and uses JavaScript to handle the game logic. The snake is controlled using the arrow keys on a smartphone, and pictograms can be added to represent the snake and apple in the CSS styles. The game starts automatically and ends when the snake collides with the wall or itself. The game over message is displayed when the game ends.
