Frequently Asked Questions
Can I choose specific categories?
The quiz automatically selects 20 questions from a pool of 65+ spanning all seven categories: Solar System, Stars, Galaxies, Space Exploration, Cosmic Records, Black Holes, and Theoretical Physics. Each game provides a balanced mix so you encounter different topics every time.
How does difficulty adapt?
The Space Quiz uses adaptive difficulty. Build a correct-answer streak and harder questions are swapped in. If you miss a question, the difficulty eases back to reinforce foundational knowledge. Every 5th question is a Mission Control bonus round worth double points, adding extra challenge and reward.
What ranks can I achieve?
There are five astronaut ranks: Space Cadet (starting rank), Flight Engineer (500+ points), Mission Specialist (1000+ points), Commander (1500+ points), and Mission Commander (2000+ points).
