EOGuessr, read the planet from orbit

A free daily satellite guessing game.

Each day, EOGuessr drops you on five real, hidden places on Earth. You read each one through five satellite signals: vegetation (NDVI), water, terrain, heat and night lights. Then you drop your pin. No account is needed to play.

You can also play Versus duels, timed Orbital Drop, Triangulate, Impostor and Regions modes, and learn how the layers work in the Academy.

EOGuessr needs JavaScript to play. Enable it and reload, or visit eoguessr.app.

EOGuessr

ORBITAL PUZZLE

A game about reading the planet the way analysts do.

Every scene is real imagery of Earth: the signal layers are Copernicus and NASA satellite data, over a high-resolution base that mixes satellite and aerial survey. You buy signals, read the clues they reveal and pin the hidden place on the map. Spend little and guess close.

The Academy explains every filter in plain words: what it reveals, when to trust it and when it lies.

Imagery and data come from the European Union Copernicus programme: Sentinel 2 multispectral, Sentinel 3 thermal and the Copernicus DEM, plus the Sentinel-2 cloudless mosaic by EOX and VIIRS night lights from NASA.
