As for "ghost players," those games are extremely rare. If QuizUp can't find a person for you to play against, you'll get set up against a demo, which takes the average answer time and responses from all players who have played those questions. Fridriksson said this occurs in less than 5 percent of games, and they do this to avoid isolating players.
"If you want to play, you should always get to play," he said.
Be aware that if you connect with a social account, your opponent will be able to see your full name and profile picture by default, though you can tweak that in your account settings. You can also turn on Privacy Mode, which means only people you have approved as a friend can see your profile or challenge you to quizzes.
QuizUp might just sound like a standard trivia game, but its social element and bazillion questions keep it interesting and make it stand out from the crowd. Plus, it is really well designed, with a crisp font, bold color scheme, and a well-organized status board for watching your progress. It also shines thanks to a few other features:
Challenge your friends: QuizUp tries to match you with a real-time opponent, so the two of you can play live. However, if you'd like to play against a friend who is offline at the time, you can challenge them to a round, submit your answers, and wait for them to play the same game later. You don't ever have to play against a stranger if you don't want to. Just challenge a friend and wait for them to accept. Playing live adds to the fun: You really feel the pressure to race against the clock to beat them. And if you do play against a stranger, QuizUp uses an algorithm to match you with compatible opponents, so no round should ever be too easy or too hard.
So. Many. Topics: With more than 400 trivia topics to pick from, there's bound to be a category for everyone. That's actually why Fridriksson believes QuizUp has been so popular.
"We have more specific topics than most other trivia games to let people play something that they are passionate about," he said.
From broader topics (General Knowledge) to the oddly specific (trivia questions devoted solely to the movie Mean Girls, which has somewhat of a cult following), QuizUp has questions to pique most people's interests. If there isn't something you fancy, let the team know and they'll consider creating your preferred category — the game frequently gets new topics. Also, once you reach level 15 in a certain category, you can apply to write your own questions for that topic. All questions are vetted by QuizUp's editorial team, but anyone can submit a ticket if they find an erroneous question or a duplicate within the same round.
