2048
- Swipe or press an arrow key: every tile slides as far as it can.
- Two tiles with the same number merge into one with double the value.
- A new 2 or 4 appears after each move. The game ends when no move is left.
Slide the tiles with arrow keys or a swipe. Two equal tiles merge into one, doubling the number. Reach the 2048 tile, then keep going for a high score.
The board is 4 by 4. Each move slides every tile as far as it can in that direction; two tiles with the same number that meet merge once per move, and the merged value is added to your score. After every move that changes the board, a new tile appears in a random empty square: a 2 nine times out of ten, otherwise a 4. Reaching 2048 counts as a win, but you can keep playing. The game ends when no move changes the board. Undo takes back your last move once. Your best score is kept on this device.
