A playable Tetris game 2. All seven tetrominoes 3. Rotation functionality 4. Line clears 5. Increasing speed 6. Next-piece preview 7. Score tracking I need to create a single index.html file in the current directory with: - CSS in a <style> tag - JavaScript in a <script> tag - No external resources, CDNs, or network requests Let me start by creating the basic structure: 1. HTML skeleton 2. Canvas setup for the game 3. Game logic including: - Tetromino shapes and rotations - Game board - Movement (left, right, down) - Rotation - Line clearing - Score tracking - Speed increase - Next piece preview 4.
