60 free Impossible trivia questions with answers — trivia quiz, new questions added Aug 2026.
These impossible trivia questions are for the person who wins every pub quiz and is bored of it. Nothing here is guessable from general knowledge: you need to know that Palau's capital has no permanent residents, that a barn is a unit of area, that four elements are named after one Swedish village, and which pope reigned for twelve days. The 60 questions are spread across geography, science, history, literature, music, film, sport, food, art, space and technology, so no single specialist can run the table. Difficulty sits at the top of our scale, from very hard to almost nobody-gets-this. Use it as the tiebreaker round, the final-jeopardy substitute, or a way to humble a friend who thinks they know everything. Impossible does not mean unfair. Every answer was checked against a reference page and cited before publication, so each question has exactly one defensible answer.
