2048

The game involves moving tiles with numbers on them around a 4x4 grid. Tiles start with a 2 on them, and each time two matching tiles touch they combine. A 2 title touching a 2 tile would become a 4 tile, two 4 tiles touching would create an 8 tile, and so forth. The objective is to keep combining tiles to form a 2048 tile, but if the grid fills with tiles and there are no valid moves left, the game is over.
