Program thinking
Custom game rules:
- Adaptive full screen, 4x4 grid
- Operation only: 4 actions up, down, left, and right
- A 2 or 4 appears randomly in the blank space (non-collision)
- Operate one direction to merge and add the same numbers
- Game starts: Two numbers are randomly placed, 2 or 4
- Failure condition: all grids are full and merging cannot be performed
- Victory condition: Win when the maximum number reaches 2048
- Scoring: Sum of all numbers on the screen
- Start button: start over
- Historical high score: persistent record, updated if the current score is greater than the historical high
Basic style implementation
The game interface is first fully implemented through CSS + HTML, and then the game logic is implemented through JavaScript.
