Accurate and Fair
Facts follow standard school and university textbooks and organisations such as NASA and the International Astronomical Union. Easy questions suit primary and middle school; hard ones ask about absolute zero, chromosome pairs and Saturn's largest moon. Teachers use it as a lesson starter and students use it for revision before tests.
The right answer stays on the server until you have answered, so nobody can peek, and both players always face the same question. Spotted a mistake? Use the feedback link in the footer and we will fix it.
