Build a playable 2048 game with arrow-key tile sliding and merging, smooth animations, a score, and win and lose states.

assistant

I'll create a standalone 2048 game in a single HTML file with CSS and JavaScript. The game will include arrow key controls, tile sliding/merging, smooth animations, score tracking, and win/lose states.

Could not find edits[0] in index.html. The oldText must match exactly including all whitespace and newlines.

I need to fix the edit operation. Let me check the exact content of the file first and then make the correct edit.

I see the issue. The file is truncated at the end of the script tag. Let me check the full content and make sure I have the complete text to edit properly. After reviewing the file, I can see that the script is incomplete. Let me complete the game by adding the missing functions and ensuring the code works correctly.

The 2048 game is now complete and functional. I've added all the necessary features: 1. A 4x4 grid with smooth animations for tile movement and merging 2. Score tracking that updates when tiles merge 3. Win condition (reaching 2048) with a "You Win!" message 4. Loss condition (no more moves possible) with a "Game Over" message 5. Arrow key controls for moving tiles 6. Restart functionality via space bar or button click The game includes visual feedback with animations when new tiles appear and when tiles merge. The score increases as tiles combine, and the game state is properly tracked to detect wins and losses. To play the game: - Use arrow keys to move tiles in the four directions - When two tiles with the same number touch, they merge into one with the sum of their values - The goal is to reach the 2048 tile - Press space or click the restart button to start a new game The game is fully self-contained in a single HTML file with no external dependencies.
