Order these World's Fairs by the year each opened. You place all 30 cards on one timeline, one at a time. Three wrong guesses ends the run.
World's Fairs and international expositions are the cards, named for their host city, with a note on a famous building or theme printed underneath. You're ordering them by the year each fair opened. One fair is on the timeline at the start with its year showing. Choose a gap for each new card among the fairs already placed. Pick the gap that fits and the year appears; a wrong one still puts the fair in its true spot and costs one of your three lives.
The fairs run from the great exhibitions of the industrial age through the space-age expos and on to recent events. The early fairs come thick and fast, and several cities hosted more than once, so the note matters as much as the city. Plenty of famous towers and pavilions were built for fairs, which can be your best clue if you know when they went up.
