When? Guess the Year

Test your knowledge and travel through time with four game modes: Classic, 60s Rush, Chill, and Timeline Challenge!

When was it invented? When did it first appear? When did it happen?

When? turns dates into a colorful guessing game. Enter the exact year and use each clue to narrow the timeline until you find the answer.

Choose how you want to play:

• Classic — solve each question before time or attempts run out. • 60s Rush — find as many dates as possible in one minute. • Chill — no timer, no attempt limit and no end to the game. • Timeline Challenge — drag or tap to put events in chronological order. Build combos and protect your three lives.

Explore varied questions about historical events, inventions, products, everyday objects and fictional characters. After each answer, discover a short fact and its source.
