Simple, fun and educational The questions difficulty is spot on not too easy or hard. The questions are varied and the summary adds interest and depth. The colour scheme is basic and the English poor in places but for a free app still well deserving of 5*.
Very bad English Good concept for a quiz game. I like the summary that comes up after answering the question which gives more information on the topic but the poor English makes it difficult to understand some questions.
Tf? Does anyone actually know any answers? Gawd it made me feel stupid.
Informative app One problem so far - a question which asks the closest star to our solar system. The app says alpha centauri the true answer is proxima centauri
Boring Repeats the questions after only 5 or 6 games. Hardly challenging!
Small font Certainly informative... But the explanation to the answer is in very small font.. Its too hard to read.. No option to zoom it or enlarge the font.. Fix it.. Fixed, i would give 5 stars
