2048 Aroo description

Inspired by Gabriele Cirulli game available on the web: http://gabrielecirulli.github.io/2048/
Playing is simple:
Swipe up, down, left, or right to move tiles as far as they can go across the board. In classic mode, tiles of the same number combine to make a tile with double that number. Try to get to 2048 and beyond!
