GeoGuardians
Decode an alien's riddles about Earth and triangulate the place with probes on a world map.
Every day: Daily Signal: the same set of places for everyone each day, found from riddles by launching probes on a world map, with a result grid to share. New puzzle: Once a day (the exact time is not stated).
GeoGuardians is a free geography riddle game in the browser. A small alien writing a guide to Earth gets everything slightly wrong, and you work out which place its riddle means, then find it by launching probes whose compass lines cross on the map. Daily Signal gives everyone the same places each day.
About GeoGuardians
GeoGuardians is a solo project by 0n3Up, a youth-centre activity leader in France, published on itch.io in September 2026. The frame is a curious alien Scout in orbit writing the first Guide to Earth, who misunderstands humans in amusing ways. Each riddle it sends describes a real place: a lake, a river, a volcano, a museum, a country or a capital.
You answer by launching a probe: click the map, and a compass points from that spot towards the target to the exact degree, leaving its line on the map. Two lines cross and you know where to look. Fewer probes and a closer final shot earn more points. Places are checked against their real shape, so for a lake you can click anywhere in it, for a river anywhere along it. Every place you find unlocks a logbook entry, a real photo and its Wikipedia page, and a postcard for your collection.
Daily Signal is the daily mode: the same places for everyone that day, and a result grid you can share. Other modes include Survey (countries, capitals, regions of France and US states), a timed Orbital Race, a satellite-view Landing mode, story events, geocaching-style Expeditions and real-time multiplayer lobbies for two to eight players. More than 600 places are sorted into 23 themes.
The game is free with no ads and no account, in French and English, and is designed for ages 13 and up while staying readable for younger players, which makes it useful in classrooms.
How to play GeoGuardians
- Open GeoGuardians and choose Daily Signal.
- Read the alien's riddle and work out what kind of place it describes.
- Click the map to launch a probe; its compass line points towards the target.
- Launch a second probe so the lines cross, then click on the place itself.
- Finish the day's places and share your result grid.
Tips
- Launch your first probe far from where you guess the place is; widely spaced lines cross more clearly.
- Remember that any point inside a lake or country, or along a river, counts.
- Read the riddle twice: the alien's mistakes usually hide the real clue.
- Use the logbook entries afterwards to learn places for next time.
