Why we chose this prompt: 2048 has simple, fully specified rules, so there is no ambiguity about correct behavior. Merging, spawning and game over are easy to test by playing, and the animation has to stay in sync with the board state.
Build 2048. Use the standard rules: a 4 by 4 grid, arrow keys slide all tiles, equal tiles merge into their sum, a new tile spawns after each valid move, reaching 2048 wins and running out of moves is game over. Animate slides and merges and show the score.
