2048 Tile

The aim of the game is to get the 2048 tile, which is certainly no easy feat. You'll start with some low tiles like 2s and 4s, which you can slide in any direction (but not diagonally). When two tiles of the same number touch, they'll join to form one tile with a higher number created by adding the two numbers together. So two 4 tiles make an 8, two 8 tiles make a 16 and so on.
You need to continue merging the tiles until you get that all-important 2048 tile, which will win you the game. But the catch is that every time you move your tiles, even if you don't manage to merge any in that move, a 2 or 4 tile will appear on the grid. Run out of space and it'll be game over.
The app will keep track of your best score so you can see how much you're improving, and there's a leaderboard that'll let you see how well you're doing in comparison with your friends if you log in with social media.
There's really nothing bad I can say about this game. I myself have become completely addicted to it, and enjoy wasting away the time on my commute home attempting to get that elusive tile (and beyond, which you can by the way)
