Today's Free App of the Day is Bubbles Touch
This is one of those games where you shoot at the descending bubbles, matching them to remove rows. The reviews indicate it's "good enough."
Seven of nine reviews are four stars and above. Only one seemed to be from the developer. :D These types of games are good time wasters...ask me how I know. ;)
