2048

This is another game I haven't played for a while but I keep it on my phone just because. The game starts with a few blocks with numbers on them, usually a 2 or 4. You have to combine them to create higher numbers. Only 2 and 2 can combine, 4 and 4, 8 and 8, etc. The object of the game is to get a high block number and it ends when the blocks take up the whole screen. It was pretty addicting at first, but now I just play it whenever I feel like trying to beat my old score.
