Roundle

A spin-off of Subwaydle for the London Underground. Each puzzle names a start and end station, and the answer is a specific set of three train lines that makes the trip with valid interchanges. Colour feedback marks lines that are in the right leg, in the trip but misplaced, or absent. An optional challenge restricts guesses to Night Tube services.
