Browser Tetris

This repository contains a self-contained browser-based Tetris clone implemented with vanilla HTML, CSS, and JavaScript. The main entry point is index.html, which loads the styling from styles.css and the game logic from tetris.js.

Getting Started

You can launch the game by serving the root directory with any static file server. For example, using Python:

python -m http.server 8000

Then open http://localhost:8000 in your browser to start playing.

Testing

Before merging any changes, smoke test the game in a desktop browser:

1. Start the local development server as described above.
2. Press Start and confirm the active piece begins falling.
3. Verify keyboard input (left/right, rotate, soft drop, hard drop, hold) behaves as expected.
4. Clear at least one line to ensure scoring, line, and level counters update.
5. Pause and resume the game, then trigger a game over to confirm the reset flow works.

If any of these actions fail, fix the issue before merging.
