Released on March 9, 2014 and developed by a 19-year-old Italian (Gabriele Cirulli), 2048 has become a phenomenon within a few days on the net. This puzzle game, with basic concept and graphics, will require you to juggle with powers of 2 until successfully getting the magic number of 2048 in a space. To do this, simply use the arrow keys to drag the tiles in one direction. Identical numbers add up and each move reveals a new number 2 in a free space. Difficult games are very trendy at the moment (see Flappy Bird) and even its author has never managed to finish this game.
