2048

How to play

1. Move with the arrow keys, W A S D, or by swiping on the board. All tiles slide as far as they can.
2. Merge: two touching tiles with the same number join into one with double the value, and you score that value.
3. After every move a new 2 (or sometimes 4) appears in an empty cell.
4. Win by making a 2048 tile – then keep going for a higher score. The game ends when the board is full and no merge is possible. ↶ Undo takes back your last move.

Tip: keep your highest tile in a corner and build a chain of falling values next to it. 2048 was created by Gabriele Cirulli in 2014 as open source; this version is written from scratch.
