Move the block using the arrow keys, WASD or swipe over the screen. For example, if you press the right arrow every block moves as far to the right as it can. If two blocks with the same number on it collide, they merge into one block with double the number on it and the score goes up by number of the new block. Try to get a block with the 2048 number on it. This game is not mine, for more information on the game here https://en.wikipedia.org/wiki/2048_(video_game)
