Build a playable Tetris on a canvas with all seven tetrominoes, rotation, line clears, increasing speed, a next-piece preview, and score.

I'll create a fully playable Tetris game using HTML5 Canvas with all the features you requested. This will be a complete single-page application with all code inline. Let me start by reading the current state of the workspace to understand what I'm working with.
I'll create a complete, playable Tetris game for you. Let me build this systematically

The workspace is empty, so I'll create the complete Tetris game as a single HTML file. Let me plan the structure: 1. **HTML structure**: Basic HTML5 page with canvas element 2. **CSS styling**: Game layout, colors, and responsive design 3. **JavaScript game logic**: - Canvas rendering - All 7 tetrominoes (I, O, T, S, Z, J, L) - Rotation system (SRS - Super Rotation System) - Movement controls (keyboard) - Collision detection - Line clearing - Gravity/speed increase - Next piece preview - Score system - Game over detection I'll use the standard Tetris colors and implement proper rotation matrices for each tetromino.

Great! The file was created successfully. Let me verify the game works by reading a portion of it to make sure all the key components are present.

Good! The file has been created successfully. Let me verify that the game assets are properly self-contained by checking if there are no external dependencies.
Perfect! I've created a complete, playable Tetris game in a single HTML file. Here's what I built for you: ## Features Included: ✅ **All Seven Tetrominoes**: I, O, T, S, Z, J, and L pieces ✅ **Rotation System**: Both clockwise (arrow up) and counter-clockwise (Z key) rotation ✅ **Line Clears**: Complete lines are removed with scoring ✅ **Increasing Speed**: Level increases every 10 lines, making pieces fall faster ✅ **Next-Piece Preview**: Shows the upcoming tetromino ✅ **Score System**: Points for clearing lines (100, 300, 500, 800 per line) and soft/hard drops ✅ **Game Over Detection**: When pieces reach the top ✅ **Full Controls**: Arrow keys, spacebar, Z, P, and N for new game ## Controls: - **←/→**: Move left/right - **↓**: Soft drop (earns 1 point per row) - **↑**: Rotate clockwise - **Z**: Rotate counter-clockwise - **SPACE**: Hard drop (earns 2 points per row) - **P**: Pause - **N**: New game (works even after game over) ## Visual Features: - Gradient background with sleek dark UI - Shaded blocks with lighting effects for 3D appearance - Next piece preview - Score, lines, and level display - Controls reference panel - Pause and game over overlays The game runs at ~60 FPS and increases in difficulty as you progress. All code is self-contained with no external dependencies! Open **index.html** in your browser to play!

RUN
EVALUATION
Functional Tetris with pieces falling, score/level/next-piece UI, and visible response to arrow key input moving/dropping pieces.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
