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.

<thinking>The task is to create a simple version of the 2048 game using HTML, CSS, and JavaScript. The game will have a 4x4 board, and I need to ensure the required behaviors are implemented. I will create a self-contained `index.html` file with inline CSS and JavaScript. Here are the steps I will take: 1. Create the basic HTML structure for the game. 2. Add inline CSS to style the game board and tiles. 3. Write JavaScript to handle the game logic, including tile sliding, merging, scoring, and spawning new tiles. 4. Implement event listeners for arrow keys to prevent page scrolling and to handle game moves. 5. Verify the game by playing a sequence of moves and checking the expected behaviors. </thinking> <thinking>Now that the `index.html` file has been created and the game logic implemented, I will verify the required behaviors by playing a short sequence of arrow-key moves and checking the expected outcomes. I will also test the 'New Game' button to ensure it resets the board and score.</thinking>

I verified the initial state of the game, which shows two tiles with a score of 0. This matches the expected behavior. Next, I will perform a sequence of moves to check the sliding and merging of tiles, as well as the spawning of new tiles. I will use the arrow keys to move the tiles left, right, up, and down, and observe the changes in the board and score. After performing the moves, I will check the following: - Tiles slide correctly when moving left, right, up, and down. - Adjacent equal tiles merge once per tile per move. - The score updates correctly when tiles merge. - A new tile is spawned in an empty cell after a valid move. - The 'New Game' button resets the board and score. I will now proceed with these checks. {"action":"inspect"}
