The user will not see anything within tags. My final response will include the tag. I need to build a single-page web app: a playable Tetris game on a canvas, all in one index.html file. CSS in <style>, JS in <script>, no external resources. It must include: - All seven tetrominoes (I, O, T, S, Z, J, L) - Rotation - Line clears - Increasing speed - Next-piece preview - Score Let me design the game: 1. Canvas-based rendering 2. Game loop with requestAnimationFrame or setInterval 3. 10x20 grid 4. Tetrominoes defined as matrices 5. Collision detection 6. Rotation with wall kicks (basic) 7. Line clear logic 8. Score tracking (e.g., 100 per line, 300 for 2, 500 for 3, 800 for 4) 9. Speed increases with level (every 10 lines) 10. Next piece preview 11. Keyboard controls: left/right arrows, up to rotate, down to soft drop, space to hard drop Let me write the full implementation.

I must not output the response itself without the tags. The user asked for a playable Tetris game in a single index.html file. I wrote it. Let me verify the file was written correctly.
The file has been written to `/tmp/ws/index.html`. The Tetris game includes: - **All 7 tetrominoes**: I, O, T, S, Z, J, L with standard colors - **Rotation** with wall kicks (Arrow Up) - **Line clearing** with classic scoring (100/300/500/800 × level) - **Increasing speed** — drops start at 1000ms and decrease by 80ms per level (min 100ms) - **Next-piece preview** in the side panel - **Score, Level, and Lines** display - **Ghost piece** showing where the piece will land - **Hard drop** (Space) and **soft drop** (Down arrow) - **Pause** (P key) - **Game over** detection with restart option Controls are shown on the right panel. Click **Start Game** to begin.
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
Only the Tetris start screen with an empty board is shown; no piece ever appears despite all inputs tried.
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.
