About QuoAnno

A better sense of when.

QuoAnno is a timeline guessing game about everything that happened: empires and inventions, dinosaurs and discoveries, films and internet culture, art and exploration.

Not just a history quiz

The point is not to memorize a textbook. It is to build intuition for scale. Julius Caesar, T. rex, the last dodo, the first iPhone and the formation of Earth all belong on one continuous story.

That is also why the game scores by distance rather than by right or wrong. A guess forty years out and a guess four centuries out are not the same answer, and a game that treats them alike throws away the only thing it was measuring. What a timeline game is sets out the format in full.

One timeline, thirteen subjects

Questions come from natural history, ancient and medieval history, the modern era, science, technology, space, art and culture, film and television, music, the internet and gaming, exploration, sport and archaeology. Mixing them is deliberate: chronology only becomes useful once a fossil, a treaty and a product launch share one axis.

BC and AD

QuoAnno uses the traditional BC and AD labels in its player-facing timeline. AD is the Latin Anno Domini. Scientific dates are still stored with explicit uncertainty when the evidence only supports an approximate range. BC and AD explained covers the missing year zero and how BCE and CE compare.

Calm by design

No account is required. There are no energy meters and no five-question wall. Endless Mode lets you play one event or fifty, while Daily Mix offers one shared ten-event set each day. Your local browser remembers your progress.

Content quality

Questions are written to make the claim itself precise. If an “invention” involved several people, the question names a specific milestone. If an ancient or scientific date is approximate, QuoAnno can accept a range rather than inventing false precision. How we know when things happened explains where those dates come from.
