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 with all the features in a single self-contained HTML file. The requirements are: - Arrow-key tile sliding and merging - Smooth animations - A score - Win and lose states I need to create an index.html file with: - HTML structure for the game board - CSS for styling (inline in <style>) - JavaScript for game logic (inline in <script>) - No external resources, CDNs, or network requests Let me plan the implementation: 1. **HTML Structure**: - Container for the game - Header with title and score display - 4x4 grid container - Win/lose overlay - Restart button 2. **CSS**: - Grid layout for the 4x4 board - Tile styling with colors based on values - Animations for tile movement and merging - Responsive design - Smooth transitions 3. **JavaScript**: - Game state: 4x4 grid, score, game over/win state - Initialization: start with two random tiles - Input handling: arrow keys - Move logic: slide tiles, merge matching tiles, update score - Add random tile after each valid move - Check for win (reach 2048) and loss (no moves left) - Animations: CSS classes for movement/merge effects Let me write the complete file.
I'll create a complete playable 2048 game in a single HTML file with smooth animations, arrow key controls, score tracking, and win/lose states.

EVALUATION
2048 game responds correctly to arrow keys with tile merging and score updates, but WASD/click/wheel don't work (unintended).

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.
