Sure! Here's an example of a simple game implemented as a single HTML file, using JavaScript and pictograms to represent Minecraft blocks. This game allows you to place a block in a 3x3 grid by tapping on the grid cells on a smartphone.
To play the game:
1. Copy the above code and save it as an HTML file (e.g., `minecraft_block_game.html`).
2. Open the file in a web browser or any HTML viewer on your smartphone.
3. You'll see a 3x3 grid of cells.
4. Tap on any cell to place a Minecraft block (represented by the "◼️" pictogram).
5. You can tap on multiple cells to add more blocks.
6. Have fun playing with the Minecraft blocks!
