If you Know It… you better think fast! Each day you’ll be asked to answer three qualifying, multiple choice trivia questions. As the day goes on, the options increase as do the points up for grabs. Questions are launched simultaneously across all devices! Keep your notifications on as you’ll need to be quick! Points begin to tickdown as soon as the question appears. The faster you are to answer, the more points earned! While three correct answers will earn you a massive point haul, it takes just one correct answer to qualify for the List! The List! Voted on the day before, each day, those who answered at least one qualifying question correctly will participate in The List. Each list contains sixteen possible answers, four of which are incorrect. The more correct answers chosen the more points earned… but be warned! Hitting one incorrect answer will cost you not only the points earned on The List, but all points earned throughout the day! Go all the way by selecting all 12 correct answers and you will earn the maximum number of points plus a speed bonus! Master the Categories - Collect the Badges! Each day, you’ll answer questions on a wide range of topics. From Animals, to Sports, to The ‘80s, and everything between. As you answer questions in each category, you’ll be able to earn badges and share your achievements with friends. A League of Your Own! Claiming the top spot on the global leaderboard always feels good, but know what feels better, claiming the top spot amongst your friends! Create your own groups with your family, or your colleagues for a friendly office competition, or even just amongst friends to see where you stack up! Share Your Success! Share your badges, your spot on the leaderboard, and your best correct answers with your friends and family. In the meantime, invite them to play with you (don’t worry you’ll already have the head start!)
