Looking for trivia questions to test your knowledge or host a quiz night? Below is a curated collection of 50 high-quality trivia questions with answers across five categories: science, history, geography, entertainment, and sports. Use them for pub quizzes, family game nights, study breaks, or daily practice.

A quick learning tip before you start. Trivia sticks best when you treat it as retrieval practice, not a reading exercise. In a landmark Science study, Roediger and Karpicke (2006) found that students who self-tested retained about 61% of material after a week, versus roughly 40% for those who only reread. Cover each answer, attempt the question, then check — even guessing wrong strengthens the memory more than rereading does.

Categories covered: Science, History, Geography, Entertainment, Sports.
