Use arrow keys (or swipe on mobile) to slide tiles. Matching tiles merge into one. Reach 2048 to win.
Every move slides all tiles in one direction; two tiles with the same number that collide merge into one tile with double the value. After each move, a new 2 or 4 tile appears in a random empty spot. The game ends when the board is full and no merges are possible.
