History Trivia is a history game played on a world map that repaints itself for each era. It is run by Mateus Araujo Santos, an individual based in Brazil. By playing, you agree to what follows.
Using the game
The daily round is free and needs no account. You may play it and talk about it anywhere you like. What you may not do is take the game apart to compete with it: no scraping the event database, no copying the questions or map data into another product, and no automated access that degrades the game for other people.
Historical content — please read this one
Every event in this game carries its sources, and getting history right is the thing we care about most. But a game is not a textbook, and three honest limits come with the format:
- Dates can be disputed. The further back you go, the more historians disagree — and this game goes back to 60 BC.
- The map is illustrated, not cartographic. Territories are a deliberate simplification of who controlled what in a given year. Real borders were messier, often contested, and frequently unknown even to the people living inside them.
- One year has to stand for a whole era. Each era is drawn at a single moment, so events decades apart share a map that was only ever true once.
Play it to get curious, not to settle an argument. Do not cite it in your homework, your thesis, or anything that matters — go to the sources instead. We correct mistakes when we find them, and we would genuinely like to hear about any you spot.
Subscriptions
A paid subscription is planned, which will unlock the other eras, unlimited play, and rooms to play with friends. It does not exist yet. When it does, its price, billing and cancellation terms will be stated clearly before you are asked to pay for anything, and this page will say so.
Who owns what
The questions, the written event summaries, the artwork and the code belong to Mateus Araujo Santos. The underlying map geometry is derived from Natural Earth, which is in the public domain, and we are glad to say so. Historical facts belong to nobody.
No warranty
The game is provided as it is. It may be unavailable, it may lose your progress if you clear your browser data, and it may contain errors. To the extent the law allows, Mateus Araujo Santos is not liable for any loss arising from using it — which, for a free trivia game that stores nothing about you, should be a small thing to agree to.
Governing law
These terms are governed by the laws of Brazil. If you are a consumer, this does not take away the protections you have under the law of the country you live in.
