Which Decade?
Place inventions, discoveries, culture and sport on the timeline from the 1870s to the 2020s. Pick the decade, sort events in order, and get a near miss when you are one decade off.
Which Decade? is a history and pop culture quiz built around one question: when did it happen? More than 320 events from the 1870s to the 2020s are mixed into decade pickers, yes or no checks, which-came-first duels, find-the-event rounds and timeline sorting puzzles, so every run feels different. Events span science and technology, culture, world and society, and sport and everyday life.
Each run has up to five rounds of eight questions, with three hearts, a timer, and lifelines for 50:50, skip and freeze. Choose from a row of decade chips: an exact hit scores in full, a pick one decade off counts as a near miss with partial points and no lost heart, and anything further costs a heart. The background takes on the colours of the answer's era, a timeline tracks your round, and four correct answers from four different decades earn a Time traveller bonus.
Your progress is saved on your device. Each correct event fills a time capsule for its decade, raising mastery and unlocking titles from Time Tourist to Keeper of Time. Earn ranks and coins for new looks and perks, finish three daily goals and play a daily quiz for stars and a streak. A good game for history fans, trivia lovers and families. Tip: use the neighbouring decades to narrow down a guess.
How to play
Read each event and tap its decade, or sort and compare events on the timeline. An exact decade scores in full, one decade off is a near miss with partial points and no lost heart, and anything else costs a heart. Use 50:50, skip or freeze when stuck. Finish five rounds, or play the daily quiz of ten questions with no hearts to lose.
