Londoners revel in their civic sense, from memorising the tube map, to telling black cabs from the Addison Lees. They understand postcode peculiarities, know not all oysters are for eating, and avoid Oxford street on a Saturday.
But say you landed in an unfamiliar part of the city, emerging from a telephone box Dr-Who style, would you be able to guess where you are?
Rob Manuel, editor of usvsth3m, told the Independent: “The inspiration came from visiting my friend Ben Goldacre and watching him play GeoGuessr. He's very good at it, much better than me and I wondered if I'd do better with a version that was only London. Limit the game to stuff I know.
“So I asked our lead coder Tom if he could do a London Guessr - he said yes - then we decided to make it multiple choice because no one in the office knew where London borough boundaries began or ended - so it moved away in execution from being a complete clone of GeoGessr and turned into it's own thing. “
