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 in a single HTML file with: - Arrow-key tile sliding and merging - Smooth animations - A score display - Win and lose states I'll create a complete, self-contained index.html file with all CSS and JavaScript inline. No external resources or CDNs. Let me plan the implementation: 1. HTML structure: - Game board (4x4 grid) - Score display - New game button - Win/lose overlay messages 2. CSS: - Grid layout for the board - Tile colors based on values - Smooth animations for sliding and merging - Responsive design 3. JavaScript: - Game state management (4x4 array) - Move logic for all 4 directions - Tile merging logic - Random tile spawning (2 or 4) - Win detection (2048 tile) - Lose detection (no valid moves) - Score tracking - Animation handling Let me write this all in one file.
I'll create a complete 2048 game with all the features you requested. Let me build this in a single HTML file.

I've created the complete 2048 game. Let me verify the file was created correctly and summarize what I built.
I've created a fully playable 2048 game in `index.html`. Here's what's included: **Features:** - **Arrow key controls** - Use ↑↓←→ to slide tiles - **Smooth animations** - Tiles slide smoothly, new tiles pop in, merged tiles pulse - **Score tracking** - Current score and best score (saved to localStorage) - **Win state** - Shows "You Win!" when you reach 2048, with "Keep Playing" option - **Lose state** - Shows "Game Over!" when no moves remain - **New Game button** - Start fresh anytime **Technical details:** - Complete game logic: tile movement, merging, random spawning (2 or 4) - Responsive design - works on desktop and mobile - Mobile controls - on-screen buttons + touch swipe support - Color-coded tiles from 2 to 2048+ with proper styling - All CSS and JavaScript inline in a single file - No external dependencies or network requests The game runs entirely sandboxed with smooth CSS transitions for tile movement (0.15s ease-in-out) and animations for new/merged tiles.
TAKE IT TO CODE

EVALUATION
Functional 2048 game responding to arrow keys with tile merging and score updates; WASD also worked (likely bound to arrows too).

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.
