GnarlyQ

GnarlyQ turns a trivia list into a push-your-luck game. Each day brings five rounds, and each round asks a question with ten possible answers, of which five are correct. You tap the answers you know, one at a time, and every right one adds to your score.

The catch is that a single wrong tap ends the round, and you lose the points you were building in it. So after each correct answer you choose: tap another, or lock in what you have. Knowing when to stop matters as much as knowing the answers.

Everyone gets the same puzzle each day, and a full game takes about three minutes. It suits players who like list trivia such as Sporcle quizzes and enjoy the tension of deciding whether to risk one more.
