GEOGRAPHY GUESSING FOR CHROME
Explore the
world.
geoplonk is a Chrome extension that turns exploring Google Maps into a geography guessing game. Use the landscape, road signs and buildings around you to work out where you are, then place your guess on the map.
The current development build is free to play and does not require a geoplonk account.

WHY THIS EXISTS
Why build
geoplonk?
geoplonk began with the idea of making geography guessing more accessible while giving players more control over their Google Maps experience.
Recognising a language, noticing the shape of a road sign or finding a familiar landscape can turn an unknown location into a solvable puzzle. The aim is to make that experience easy to enjoy, whether you want to improve your geography knowledge or simply explore somewhere new.
Building geoplonk as an extension keeps exploration on the original Google Maps website while adding interface customisation, movement restrictions and an optional guessing game. Those controls also make the extension useful when you want to explore without playing.
The project is currently focused on singleplayer. Its modular design leaves room for future features, including multiplayer, while feedback on the current build helps improve the experience.
