This is by far the most used game on my phone, I know that sounds lame with all the other (much more awesome games) that are out there. The reasons are simple. I'm busy and this app loads quickly, saves my games automatically, and never freezes on me. I can pick this game up between appointments at work, on the can, or during breakfast. Some other games are too taxing to play for just a few minuets. My favorite games are the Tower Defense games (robo rocks), but when it comes to finding a game you can pick up for five minuets here and there, this is by far the best!!
