Knowledge Trainer: Trivia is the quiz game for smart people. It’s designed to stimulate your brain with over 6,000 high-quality, challenging, and informative questions. Each trivia lesson tests your wits with 10 questions from 10 different categories. The difficulty level depends on you: get an answer right, you'll move up a level. A wrong answer leads to an easier question. But you'll want to move up to improve your Knowledge Quotient, recalculated after every round. More app features: • 60
