As it turns out this addicting little game started getting downloaded like hotcakes on Android phones as soon it was available for free at GetJar. Prior to that, this little app just wasn't as popular as it was on the iPhone. Some iPhone users are probably getting a little pissy since they had to pay a whole dollar on iTunes to pick it up. Now with over million downloads it's about ready to take over the world. If you don't know what the game is all about, check it out here. If you're one of the last few Android users that don't yet have it, hurry up and grab it for free while you still can. Source
