50 free Eureka (TV Series) trivia questions with answers — trivia quiz, new questions added Oct 2026.
Eureka ran for five seasons as one of cable's best-loved science fiction comedies, set in a hidden town where nearly everyone is a genius and nearly every experiment goes wrong. At its centre is Jack Carter, an ordinary lawman whose common sense keeps rescuing people far smarter than he is. This quiz covers the full run: the residents of the town and the actors who played them, the guest stars who dropped by (Felicia Day among them), the story arcs behind Global Dynamics, and the episodes fans remember best, from the pilot to the finale. It suits a rewatch party, a trivia night, or anyone who misses Café Diem. The questions start easy and get harder, and every answer comes with a short explanation.
