2048 is played on a simple 4×4 grid with tiles of varying colors overlaid that slide smoothly when a player moves them. The game uses the arrow keys to move tiles left, right, up, and down. If two tiles of the same number collide while moving, they will merge into a tile with the total value of the two tiles that collided. Every turn, a new tile will randomly appear in an empty spot on the board with a value of 2.
