Guess the ROUNDLE in 6 tries.
\nEach guess must a be a valid train trip involving 3 trains using valid interchanges between them.
\nYou need to guess a specific set of three trains that can make the trip.
\nMultiple routings may be possible to make the trip, but your goal is to\n find the one routing that matches the puzzle of the day. The solution may or may not be the fastest or efficient routing.
\nRouting for each train line is based on weekday off-peak schedule (i.e. Edgware to Morden - Northern line trains travel via Bank only, no fast/semi-fast Metroplitan line trains).
