THE PLAYBOOK
How to play
One historical moment. One year to guess. Then a reveal that makes the date worth remembering.
Try a practice round →Start with a clue
Read the event description closely. Look for people, places, inventions and world changes that help narrow the century. In our practice game, you have 25 seconds per clue and seven clues in a round.
Make one year guess
Type a four-digit year and press Enter or choose “Lock in year.” You can also skip. After you answer, the correct year and a source link appear. A skipped or timed-out clue earns zero points.
Learn from the reveal
Open the cited source to read the wider story. Your score depends on the distance between your guess and the recorded year; see the practice scoring guide for exact bands.
