The Prompt
Create a complete, self-contained HTML page that implements the popular game “2048” with the following features:
– A 4×4 game grid representing the game board.
– Controls enabling players to move tiles up, down, left, and right using keyboard arrow keys.
– Game logic that merges tiles with the same number when they collide during moves.
– A live score counter that updates accurately as tiles merge throughout gameplay.
– A restart button that resets the game board and score to start a new game.
– CSS styling to make the game visually appealing and user-friendly.
### Requirements:
– No external libraries or frameworks are allowed; all HTML, CSS, and JavaScript must be embedded within a single HTML file.
– The JavaScript should handle all game mechanics internally, including tile spawning, merging, movement, and score management.
– Use clear, concise comments throughout the code to explain your logic and the purpose of key sections to ensure maintainability and clarity.
– The game should respond to arrow key inputs smoothly and update the UI dynamically.
### Steps:
1. Define the HTML structure with containers for the game grid, score, and controls.
2. Style the grid and tiles with CSS to visually distinguish tile values and create a pleasant layout.
3. Implement JavaScript to initialize the game state, manage the grid array, and spawn new tiles.
4. Add event listeners for keyboard input to handle tile movements and merges:
– Combine adjacent tiles of the same number in the direction of movement.
– Update the score accordingly on merges.
– Spawn a new tile after each successful move.
5. Implement the restart functionality to reset all game variables and UI elements.
6. Include comprehensive comments explaining the logic, data structures, and flow.
### Output Format:
– A single HTML file containing all HTML, CSS, and JavaScript inline.
– Well-indented, clean, and commented source code.
### Notes:
– Make sure to handle edge cases such as no possible moves and game-over scenarios.
– Use semantic HTML where appropriate.
