I've been playing Ellen DeGeneres's new trivia app for the iPad, Know or Go ($1.99). It's based on the trivia game she plays with contestants on her show where if you get the answer wrong you drop through a hole on the ground. It's hilarious to watch if you haven't seen it (video below). The app is definitely a fun time. Ellen's voice makes funny comments throughout the entire game, and the trivia questions are wide-ranging and varied.
