Use arrow keys (↑↓←→) or WASD to slide all tiles. When two tiles with the same value collide, they merge into one with their sum. On mobile, swipe on the grid. The goal is to create a tile with value 2048 (or higher)!

Select "Custom Text" to replace numbers with your own words, emojis, or labels. Select "Custom Image" to use image URLs (supports any web image: PNG, JPG, GIF, SVG). Each tile value (2, 4, 8, ..., 2048) can have its own unique content. Click "Apply Custom Settings" to see changes on the game board.

Yes! You can use animated GIFs for lively tiles and SVG for crisp scalable graphics. Just paste the image URL into the custom input fields. Images are automatically resized to fit the tile using object-fit: contain. If an image fails to load, it will gracefully fall back to showing the numeric value.

1. Corner strategy: Keep your highest tile in one corner (e.g., bottom-right) and build around it.
2. Avoid moving up if your big tile is at the bottom.
3. Keep the bottom row full to maintain control.
4. Plan ahead — each move should set up the next merge opportunity.
5. Practice patience — don't rush to merge small tiles.

Yes! Your game state, score, and theme settings are automatically saved to your browser's localStorage. If you refresh the page or close and reopen it, you can continue right where you left off. Your high score is also persisted. Use "Reset Best" to clear the high score record.

Congratulations! 🎉 When you reach the 2048 tile, a victory overlay appears. You can choose to "Continue" and keep playing for higher scores (4096, 8192, and beyond!), or start a new game. The game doesn't stop at 2048 — true masters aim for 4096+!

For best results, use square images (1:1 aspect ratio) with a minimum size of 200×200 pixels. Supported formats: PNG (recommended for transparency), JPG, GIF (including animated), SVG, and WebP. Images are displayed using object-fit: contain, so they'll always fit neatly inside the tile without cropping.
