2048 is a single player sliding tile puzzle. It is played on a simple 4×4 grid, with numbered tiles that slide when a player moves them by sliding left, right, up or down.
The aim of the game is to merge tiles with the same values and form the tile with as high a value as possible.
The game begins with two tiles already in the grid, having a value of 2 or 4, and another tile of that type appears in a random empty space after each round. The tiles slide as far as possible in the chosen direction until they are stopped either by another tile or the edge of the grid. If two tiles of the same number collide while moving, they will merge into one tile with the total value of the two colliding tiles. The resulting tile cannot merge again with another tile during the same move.
