The gameplay of 2048 is quite simple. Press the arrow keys to slide all the tiles on the board in that direction. If two tiles of a matching number are slid into each other this way they will combine into a new tile containing the sum of the two tiles. The whole point of the game is to combine enough tiles to create a 2048 tile. Sounds pretty simple, but it is extremely challenging. Game is very well done and is incredibly addictive.
