Build a playable 2048 game using HTML elements and CSS with a 4 by 4 board. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. No third-party libraries are provided. Required behavior: - Arrow keys slide tiles toward the selected edge. Adjacent equal tiles merge once per tile per move, and the score increases by the value of each new merged tile. - For example, moving [2, 2, 2, 2] left produces [4, 4, 0, 0], not [8, 0, 0, 0]. Moving [2, 2, 4, 0] left produces [4, 4, 0, 0]. These examples describe the move before spawning a new tile. - Start with two tiles. After a move that changes the board, spawn exactly one tile in an empty cell: 2 with 90% probability, otherwise 4. Do not spawn after an unchanged move. - Animate movement and merging without allowing rapid input to corrupt board state. Prevent arrow keys from scrolling the page. - Show score, a win message on reaching 2048, and Game Over only when no valid move remains. Provide New Game to reset board and score; allow continuing after a win. Verify: Play a short sequence of arrow-key moves and check that tiles slide, a valid move adds a tile, and any observed merge updates the score by its merged value. Use New Game and check that the board returns to two tiles with a reset score.

The 2048 game has been initialized successfully. Here's a summary of the current state and next steps for verification: ### Observed Behavior: 1. **Initial State**: The game starts with two tiles (both `2`) on the board, and the score is `0`. 2. **UI Elements**: The score display, board, and "New Game" button are all present and correctly styled. 3. **Console Warning**: A minor warning about sandboxing is visible but does not affect functionality. ### Next Steps for Verification: Let's test the following key behaviors: 1. **Arrow Key Movement**: Slide tiles left/right/up/down and verify merging and scoring. 2. **Tile Spawning**: Ensure a new tile spawns after a valid move. 3. **Win/Lose Conditions**: Check if the game detects a win (2048 tile) or game over (no moves left). 4. **New Game**: Reset the board and score. I'll simulate a few arrow key presses to verify the core mechanics.

The tiles did not merge or move as expected when pressing the **ArrowRight** key. This indicates a bug in the sliding and merging logic. Let me fix the `slideAndMerge` function to ensure tiles slide and merge correctly. I'll update the logic to handle sliding and merging properly, especially for the right direction.

There is a syntax error in the JavaScript code, causing the board to not render. Let me fix the syntax error and ensure the logic is correct.

The issue is likely due to a syntax error elsewhere in the code. Let me inspect the current state of the file and fix any syntax issues.

The issue is a duplicate block of code at the end of the `slideAndMerge` function. Let me fix this by removing the duplicate code.

The game is now rendering correctly with two tiles on the board. Let's test the sliding and merging functionality by pressing the **ArrowRight** key to see if the tiles merge and the score updates.

The tiles are sliding correctly, but they are not merging as expected. The issue is in the `slideAndMerge` function, where the merging logic needs to be adjusted to ensure tiles merge only once per move. Let me fix this logic.
