What you get: You can win cash by playing the mobile trivia game HQ! Get all 15 questions correct tonight, and you’ll split the highest jackpot to date at $20,000! Tonight’s game will occur during the Super Bowl halftime.
What I get in return: Each friend who installs HQ Trivia and uses my referral code chiofsteel helps me earn an extra life (i.e. a chance to continue if I get an answer wrong). Once you play HQ Trivia, you can get an extra life by referring your friends!
Where to go: App Store and Google Play
By the way, there’s a hack to gain a free life in HQ without needing to refer new friends. I can verify that it works on an iPhone.
