Guess the Bus

Every day, one London bus route appears on the map — its shape traced across the city, its number hidden.

You get three guesses to work out which route it is.

This is a game of deduction, not memory. You don't need to know the number. You need to read the shape: where it starts, where it ends, how it crosses the river, whether it hugs a main road or wanders through the suburbs. Every wrong guess is drawn on the map beside the answer, so you can see exactly how close you were and narrow it down from there.

FREE EVERY DAY A new route every day, free forever. No ads. No account. No sign-up. It works entirely offline — the whole route map is built into the app, so nothing is ever fetched while you play.
