Chrono Trivia is a free daily history puzzle game. Each day, six new challenges appear — one per category. Your goal is to arrange four real historical events in chronological order, from earliest to most recent.
Every puzzle is built from a database of 943 verified historical events spanning from the late 1800s to today — covering Entertainment, Technology, Sports, Science & Space, World History, and Pop Culture. After completing a puzzle, you see the correct order with years revealed, plus the story behind each event.
Classic mode: sort the events. Expert mode: also guess the year. Earn badges, build daily streaks, and share your results. Play all six categories every day — each one is a fresh challenge.
