▶ Start right away

Open the app and jump straight into a quiz. No registration. No ads.

▶ Quiz your way

Choose from multiple choice, typing, saying it out loud, or tapping the globe. Pick the quiz mode that works best for you. Flag quizzes offer even more variety: name the country, pick the flag, point to the country on the globe, or color the flag. Would you like to focus on a specific region of the world? Customize the quizzes to match the topics that interest you most.

Practice regularly with the Daily Quiz – every day, a new selection of questions awaits you. The app automatically adapts the questions based on your answers: questions you answer incorrectly appear more often, while topics you’ve mastered appear less often.

▶ Multiplayer Quiz

Challenge your friends and family to play a quiz together. Pick a topic, share the code, and compete in a live quiz. Who knows the world’s capitals best? And who can really name all the countries in Asia?
