Each day there's a new mystery station. Its name and the trains that stop there are shown at the top.
The map has no labels. Tap the dot where you think the station is, then press Guess. You get 6 guesses.
A wrong guess is labelled on the map with how far it is from the answer:
A new station appears at local midnight.
