Knowledge Trainer: Trivia (2019)

the binary family GmbH

Each lesson tests your wits with 10 questions from 10 different categories. The difficulty level depends on you. Get an answer right and 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, which is recalculated after every round. In a multiplayer game, up to 4 players can compete.
