How to play
- Slide every tile with the arrow keys, W A S D, or a swipe.
- Two tiles with the same number merge into their sum, and that sum is added to your score.
- A new 2 or 4 appears after every move that actually shifted something.
- Reaching 2048 wins, but you can keep going for a higher score.
- Undo steps back one move — useful, and only one deep.
