Build a playable 2048 game with arrow-key tile sliding and merging, smooth animations, a score, and win and lose states.
thinking
The user wants a playable 2048 game in a single HTML file. Requirements: 1. Single HTML file named `index.html` 2. CSS in `<style>` tag, JS in `<script>` tag 3. No external resources/CDNs - fully self-contained 4. Arrow-key controls for sliding and merging 5. Smooth animations 6. Score tracking 7. Win state (reaching 2048) 8. Lose state (no more moves) Implementation plan: - HTML structure: container, grid, tiles, score display, win/lose overlays - CSS: Grid layout, tile styling with colors for different values, animations for sliding and merging - JS: Game logic (4x4 grid), move handling, collision detection, scoring, state management Key game mechanics: - 4x4 grid - Tiles slide in arrow direction until hitting edge or another tile - Same-value tiles merge when they collide during a move - After each valid move, a new tile (90% chance: 2, 10% chance: 4) spawns in empty spot - Win when 2048 tile created - Lose when no empty spots and no possible merges Animation strategy: - Use CSS transforms for smooth sliding - Track tile positions and use transform: translate() - Scale animation for new tiles and merges Let me write the complete implementation:

I've created the 2048 game. Let me verify it works by checking the file structure and testing the basic functionality. The implementation includes: 1. **Game Logic**: Full 4x4 grid with tile sliding and merging 2. **Arrow Key Controls**: Up, Down, Left, Right for movement 3. **Smooth Animations**: CSS transitions for tile movement, appear animation for new tiles, pop animation for merges 4. **Score Tracking**: Real-time score updates 5. **Win State**: Detects when 2048 tile is created (with golden overlay) 6. **Lose State**: Detects when no moves possible (with game over overlay) 7. **Visual Design**: Authentic 2048 color scheme and styling 8. **Responsive**: Works on different screen sizes The game is fully self-contained in one HTML file with no external dependencies.
I've created a complete, playable 2048 game in `/workspace/index.html`. **Features:** - **Arrow key controls** - Use ↑↓←→ to slide tiles - **Smooth animations** - Tiles slide and merge with CSS transitions; new tiles fade in, merged tiles pop - **Score tracking** - Real-time score display in the header - **Win state** - Golden "You Win!" overlay when you reach 2048 - **Lose state** - "Game Over!" overlay when no moves remain - **New Game button** - Restart anytime **How to play:** 1. Open `index.html` in any browser 2. Use arrow keys to slide tiles 3. When two tiles with the same number touch, they merge 4. Reach 2048 to win! The game is fully self-contained with no external dependencies - all CSS and JavaScript are inline.
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.

EVALUATION
2048 clone responds correctly to arrow keys with tile movement, merging, and score updates; no self-animation or reaction to mouse input.

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.
