Sure! Here's an example of a simple block game implemented as a single HTML file, using JavaScript and enclosed in script tags:
To play the game, you can open the HTML file in a web browser on your smartphone. You'll see a grid on the screen and can tap on the grid to place blocks. The goal is to fill up the entire grid by placing blocks in the available spaces. Once the grid is completely filled, you will receive a congratulatory alert message indicating that you've won the game.
Please note that this is a basic implementation for illustrative purposes, and you can enhance it further with additional features and styling based on your requirements and preferences.
