2) Basically it's an app called HQ Trivia which is on IOS and Android, where everyday you have a chance to win 550 if you get a seriesof questions correct. There are 12 questions in total so it's pretty hard.
3) Ifyou get a question wrong you are eliminated from the game, but there's a way to get an extra life if you refer a friend to the app. So share it with all your friends too. I won't be linking my referral code, I'm just sharing this cool app with everyone
