Guess today's mystery station on the Tube, Overground, DLR or Tram. Each guess shows the travel time to the answer and which lines you share with it.
Every date has its own puzzle, computed the same way today's is — browse back through past days or jump ahead.
Play on the whole network, or narrow it down. Each combination is its own daily puzzle with its own answer and its own saved progress — journey times are recalculated using only the networks you leave switched on.
Travel time is estimated door-to-door via the network graph — it gets you close, closer, colder as you guess. This is the one clue you always get, in both Easy and Hard mode.
Easy mode (the default — toggle to Hard for a harder game) also shows you which lines each guess is on, with the ones it shares with the answer lit up, plus a full route breakdown: your guess's fastest route broken into legs with their own times, and a pill for every station you'd change at. A change point stays masked as "change point" until you actually guess that station — guess it and it unmasks everywhere, including in earlier guesses. If two guesses share a change point, that pill is highlighted even while masked, hinting the real route runs through it. Everything unmasks once the day's game ends.
Easy mode also tells you the fare zone of each guess and whether the answer is in that same zone, further out, or closer in.
Hard mode strips all of that away — no zone, no line names, no route, just the time. You're guessing blind except for how close you are.
The networks button lets you play on just the Tube, just the DLR, and so on. Each combination is a separate daily puzzle with its own answer.
Six guesses a day. One answer, shared by everyone, resets tomorrow.
