It's free on several services, such as the first one being free on the android market. So it's not completely people who actually paid for a version of the game counting into this 1 billion downloads. Heck, I hate this game and I've got it on my android.
Sweet, the first one was mediocre at best. This game doesn't look like it's worth my time either, I wasn't ever planning on buying this game. But now this just makes me sick.
