4 stars: I lowered my rating just a little. It's still the same basic game, but now has a completely different standings system. Not sure what to think of this yet. I really enjoyed seeing my level among people in the same country and area as me as well as globally.
5 stars: Great format for international, national, and regional competitions. Different formats of quizzes as well. Plus, I have yet to spot an incorrect answer, which is unusual for these trivia games.
5 stars: Highly addictive, great questions plus a league table to keep you hooked. Fantastic app.
5 stars: Just love this quiz, so many different topics to choose from. Very varied selection of questions to answer, and with the info after each question there's plenty of information to feed your brain.
5 stars: Fun and educational learning new things and keep your brain going Thank you for coming up with a great game I enjoy very much
3 stars: My experience in Portuguese language is not good at all. I only get one game a day and don't understand why. In other languages you can play as much as you can and also you get extra games for free.
3 stars: This game is great....but i am interrupted mid game with an ad for 'Hustle Castle\
5 stars: Fun if you like a good quiz. Can sometimes accidentally answer wrongly if you don't scroll up a bit between Answering one question then pressing the next question bit.
5 stars: Love this game, learning new things each time I play it, keep improving it...
