The user wants a complete Tetris game in a single HTML file with canvas rendering. I need to implement: - All 7 tetrominoes (I, J, O, L, S, T, Z) - Rotation mechanics - Line clearing - Increasing speed - Next piece preview - Score tracking - Canvas rendering Let me plan the structure: 1. HTML5 canvas element 2. CSS styling for the canvas 3. JavaScript game logic: - Game board (10x20 grid) - Tetromino shapes and colors - Current piece position and rotation - Next piece - Score, level, lines cleared - Game state (playing, game over) - Keyboard controls (arrow keys for movement, space for hard drop, up for rotation) - Game loop with increasing speed - Collision detection - Line clearing logic - Piece spawning I'll use a single HTML file with inline CSS and JavaScript as requested. The game should be self-contained with no external resources. Let me write the complete index.html file with all the necessary code.
I'll create a complete, self-contained Tetris game in a single HTML file with all the requested features.

The user wants a complete Tetris game with all seven tetrominoes, rotation, line clears, increasing speed, next-piece preview, and score tracking. I need to create a single self-contained HTML file with embedded CSS and JavaScript. Let me plan the implementation: 1. A 10x20 game board (standard Tetris size) 2. All 7 tetromino shapes (I, J, L, O, S, T, Z) 3. Rotation mechanics (with wall kicks) 4. Line clearing with scoring 5. Increasing difficulty (speed) as level increases 6. Next piece preview 7. Score, level, and lines cleared tracking 8. Game over detection 9. Keyboard controls 10. Pause functionality I'll create a complete, self-contained HTML file with: - CSS in a <style> tag - JavaScript in a <script> tag - Canvas for the game board - Canvas for the next piece preview - Score/level/lines display - Game over screen with restart button The game should be playable with arrow keys and spacebar. I'll implement proper rotation with wall kicks, collision detection, and scoring that increases with level.

TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.
RUN
EVALUATION
Tetris board and next piece area remain completely empty/black throughout; no pieces ever render despite UI shell existing.
Vision grade · anthropic/claude-sonnet-5
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.
