To shuffle the tiles, move your fingertip left, right, up, or down. The tiles will move in that direction until those who come into contact with a boundary or another tile.
Because once two identically numbered tiles come into touch with each other, they merge to form a single tile with the value of the two tiles. For example, combining two tiles with the second spot generates one tile with the number Fuse tiles till you get one with the number.
