🧭 Ground Truth

How it works

Two ways to play: get a place name and tap where it is on the map, or get a pin and pick the right name from four options. Every guess is scored by how far off you were in km.

Three levels, all playable from the start: Boroughs, Neighbourhoods, and Stations — pick whichever matches how you actually think about London. Within Neighbourhoods and Stations, rings unlock outward from central London as you master the one before. A place counts as mastered when your last two guesses land within its mastery distance. After each guess you also see how long it takes to get there from King's Cross and Liverpool Street, plus a fact about the borough or the lines serving the station.
