Script

Sure! Here's an example of a Tetris game implemented as a single HTML file using JavaScript and enclosed in script tags. Please note that this code is a simple implementation for demonstration purposes and may not have all the features of a traditional Tetris game. Additionally, for a fully functional game, additional CSS and HTML elements are needed to create the game layout and controls properly.

To play the game, you can copy this code into an HTML file and open it in a web browser. Use the arrow keys (Up, Down, Left, Right) to control the tetromino movement and rotation. Please note that this is a basic implementation and may not have all the features or levels of a complete Tetris game. Feel free to modify and enhance it as per your requirements.
