This 2048 page is built for repeat play. The board stays centered, the score and move count stay visible, and the controls behave the same way on keyboard and touch. That makes it easier to practice the same good habits across several rounds instead of playing each board like a random sprint.
Every swipe or arrow-key move shifts the whole grid in one direction. Matching tiles merge once per move, the score rises by the merged value, and a fresh tile appears after each valid move. The classic goal is to create a 2048 tile, although you can keep playing after that for a higher score.
On desktop use the arrow keys. On mobile use swipes. The most reliable approach is to choose one home corner for the largest tile and avoid breaking the row or column that feeds into it.
