Six Bearings: Geography Guessing Game is a free geography game you play inside ChatGPT, Claude, or Gemini. A geography guessing game: find eight hidden countries from six clues each, and get a sealed distance and direction for every wrong guess. 1 or more players, 20–40m a run. No signup and no app — open it in your assistant, or paste the play prompt anywhere else.
How to start
- Open it in your AI. Tap Open in ChatGPT or Open in Claude and press send, or paste the play prompt into any assistant that can open links.
- The game loads. The host is told to load the card and its sealed file, read you the first 16 characters of its SHA-256 commitment, show how to play and the 72-country atlas, and turn up the first clue.
- Read, guess, take bearings. A clue costs one of a round's six steps and a wrong guess two; every wrong guess earns the distance and map direction from the country you named to the hidden one.
- Verify the seal. After the run, check that the countries, clues and bearings you were given match the sealed file, then rebuild its SHA-256 hash at aigamecards.com/verify.
Questions
- Can ChatGPT host a geography quiz without making up facts?
- Not reliably on its own: in plain chat it can state a wrong fact with confidence, change the country it had in mind, or work out a distance or a direction wrong. This card takes those jobs away from it. The eight countries, every clue with its sources, and a distance and direction for every guess on its 72-country atlas were sealed under a SHA-256 hash before release, and the host is told to read them and never to work a figure out. The seal shows that nothing moved; it cannot show that every reading was right, so the state line at the end of each reply shows the bearings you have earned in the round, to check against the file afterwards.
- What does the seal prove, and what doesn't it?
- It proves the sealed file did not change: its SHA-256 hash was published before release, and after the game you can rebuild it from the file at aigamecards.com/verify. It does not prove the host read every clue and bearing correctly, which is why each bearing you earn stays on screen to compare with the file. The file is public: fixed before play and checkable after, not hidden from a player who goes looking for it. Save codes are trusted as typed, not checked against the file.
- How are the distances and directions measured?
- From each country's city on the atlas: its capital, or for Bolivia and South Africa the labelled seat of government (La Paz, Pretoria). Cairo, Yamoussoukro and Amsterdam are measured as capitals, though government sits elsewhere. Coordinates come from the CIA World Factbook's last online update (January 2026; the Factbook has since been discontinued), cross-checked against GeoNames. The distance is the shortest way over the globe, taken as a sphere of radius 6,371 km, to the nearest 1,000 km, so another calculator can land on the next thousand. The direction is a grid direction, not a compass heading: where the hidden city lies from yours on a world map with north at the top and the Greenwich meridian in the middle, counting a degree of longitude the same as a degree of latitude, as one of eight points. That makes it a map game as well as a quiz; on a web or wall map, a direction close to the line between two points can look like its neighbour. For capitals far apart, the shortest way over the globe can set off in a different direction, and the host says so when it does.
- Is it a good geography quiz for a classroom, and how long does it take?
- Twenty to forty minutes for eight rounds, rated for all ages. Like most geography games for a class, it plays best with one person typing for everyone, and it never asks for a name. The eight rounds cover all five of the atlas's regions, and each finished round's sources are read out. Common English forms count (Turkey or Türkiye, Holland, Ivory Coast, UK or Britain), so do the cities printed on the atlas and a list of common misspellings. A wrong guess costs two of a round's six steps, so reading the clues scores better than guessing at random, and a question that names a country is checked with you before it counts.
- Does the chat have to be able to open a link?
- Yes. The host fetches the sealed file from aigamecards.com when the game starts; pasting it in yourself would show you every answer. Not every app can open links, and it changes; aigamecards.com/launch-matrix shows which currently do. The card itself is free and needs no account with us.
