History of the puzzle[edit]

First appeared on WPC 2016/Round 11, an "innovative" round under the name "Railroads". The author of the puzzle was Matej Uher (Slovakia). Later appeared on Puzzle GP 2019 Round 7 under the name "Endpoints", possibly to avoid confusion with Railroad Tracks, a puzzle also called Railroads.
