Build a playable Tetris on a canvas with all seven tetrominoes, rotation, line clears, increasing speed, a next-piece preview, and score.
thinking
The user wants a complete, self-contained Tetris game in a single HTML file. Let me build this with: 1. Canvas-based rendering 2. All 7 tetrominoes (I, O, T, S, Z, J, L) 3. Rotation (SRS-like wall kicks would be nice but at minimum basic rotation) 4. Line clearing with scoring 5. Increasing speed based on level/lines cleared 6. Next piece preview 7. Score display 8. Keyboard controls Let me design this carefully: - Board: 10 columns × 20 rows (standard Tetris) - Cell size: ~30px for main board, smaller for preview - Colors for each piece - Game loop with increasing speed - Controls: Arrow keys (left/right/down), Up for rotation, Space for hard drop Let me write this all out in one go.

Let me verify the file was written correctly.
The Tetris game is written to `/workspace/index.html`. Here's what's included: **Features:** - **All 7 tetrominoes** (I, O, T, S, Z, J, L) with classic colors - **7-bag randomizer** for fair piece distribution - **Rotation** with wall-kick support (tries offsets so pieces don't get stuck near walls) - **Ghost piece** showing where the piece will land - **Line clears** with scoring (100/300/500/800 × level for 1/2/3/4 lines) - **Increasing speed** — speed increases every 10 lines cleared (level up) - **Next piece preview** panel - **Score, level, and lines** display - **DAS (Delayed Auto Shift)** for smooth left/right holding - **Hard drop** (Space) and soft drop (↓) - **Pause** (P key) **Controls:** | Key | Action | |-----|--------| | ← → | Move left/right | | ↑ | Rotate clockwise | | ↓ | Soft drop (+1 pt per row) | | Space | Hard drop (+2 pts per row) | | P | Pause | | Enter | Start / Restart | The game runs entirely client-side in a single HTML file with no external dependencies.
TAKE IT TO CODE

RUN
EVALUATION
Functional Tetris with pieces falling, scoring, next preview, but a JS error suggests bugs; no line clears observed.

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.
