My SIL got me on this app and it is totally fun! It is a trivia game that gives you the chance to win some serious cash! Of course, you have to be quick and 100% correct.
Today I played one game, I got 8/12 questions right so I was eliminated but it was still fun. The prize was $5K and the live chat was going off with people from all over the world.
Give it a try!
