How to play

One Tube line a day, its stations coloured by today's number. One station is showing the wrong one. Tap or type a station and accuse it. Six guesses.

Each wrong guess gives you a clue you can count along the line: first which way the imposter is from your station ("towards Euston"), then roughly how many stops, then exactly how many. Stations that can't be it get hatched.

Knowing London gets you there in one or two. Working it out from the clues alone takes about four.

Your share shows how many stops each guess was from the imposter: 🟥 8 or more, 🟧 4–7, 🟨 3 or fewer, 🟩 found.

One station is showing a neighbour's number instead of its own. Accuse one: each miss tells you which way the imposter is from there, then how far.

Colours rank the stations on today's line, lowest to highest.
