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 me to build a playable 2048 game as a single-page web app in one self-contained `index.html` file. The requirements are: 1. Arrow-key tile sliding and merging 2. Smooth animations 3. Score display 4. Win and lose states 5. No external resources, CDNs, or network requests 6. CSS in `<style>` tag, JS in `<script>` tag, all inline I need to create a complete 2048 game implementation. Let me think about the structure: 1. HTML structure: Game container, grid, score display, game over/win messages 2. CSS: Style the grid, tiles, animations, responsive design 3. JavaScript: Game logic including: - 4x4 grid initialization - Random tile generation (2 or 4) - Arrow key handling for sliding tiles - Merging logic - Score tracking - Win condition (reach 2048 tile) - Lose condition (no more moves possible) - Smooth animations for tile movement and merging - New game functionality Let me write this as a complete self-contained HTML
I'll create a fully functional 2048 game with smooth animations, score tracking, and win/lose states in a single HTML file.

The user asked me to create a playable 2048 game with arrow-key tile sliding and merging, smooth animations, a score, and win and lose states. I've created the file `index.html` with all the requirements: 1. ✅ Arrow-key tile sliding and merging - implemented with keyboard event listeners for ArrowUp, ArrowDown, ArrowLeft, ArrowRight 2. ✅ Smooth animations - implemented with CSS transitions and keyframe animations (pop for new tiles, merge for merged tiles) 3. ✅ Score display - implemented with score tracking and display 4. ✅ Win and lose states - implemented with hasWon() and isGameOver() functions, showing messages 5. ✅ Single self-contained file - everything is in index.html with inline CSS and JS 6. ✅ No external resources - no CDNs, all self-contained 7. ✅ CSS in <style> tag, JS in <script> tag - done correctly The game includes: - A 4x4 grid - Random tile generation (2s and 4s) - Proper merging logic - Score tracking - Win condition (reach 2048) - Lose condition (no more moves) - Smooth CSS animations for tile movements and merges - Touch support for mobile devices - New Game button - Attractive gradient background with glassmorphism effects I should verify the file was created correctly by reading it back or checking if it exists
I've created a fully functional 2048 game in `/workspace/index.html`. The game includes: **Features:** - **Arrow key controls** - Use ↑↓←→ to slide tiles - **Smooth animations** - CSS transitions and keyframe animations for tile movement, merging, and new tile appearance - **Score tracking** - Points increase when tiles merge - **Win state** - Displays "You Win!" when reaching 2048 - **Lose state** - Displays "Game Over!" when no moves remain - **Touch support** - Swipe gestures work on mobile devices - **New Game button** - Restart anytime - **Visual design** - Gradient background, glassmorphism effects, color-coded tiles **Game mechanics:** - 4×4 grid with random 2 and 4 tiles appearing after each move - Tiles slide and merge when they collide with matching values - Score accumulates from merged tile values - Game detects win (2048 tile) and lose (no valid moves) conditions The file is completely self-contained with no external dependencies - all CSS and JavaScript are inlined. You can open `index.html` directly in any modern browser to play!
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
2048 game responds to arrow keys with tile merging and score update, but WASD doesn't move tiles from prior arrow state as expected.

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.
