Sure! Here's a simple implementation of Minesweeper as a single HTML file using JavaScript. This game is designed to be played on a smartphone, and it uses pictograms to represent the mines and numbers.
To use this code, please save it as an HTML file (e.g., `minesweeper.html`), and open it in any web browser on your smartphone. The game will start automatically, and you can click on the cells to reveal them. If you click on a mine, the game is over, and all cells will be revealed.
Note: This is a simplified version of Minesweeper and does not include features like flagging mines or timers. You can enhance the game by adding those features if desired.
