Train Tracks is a logic puzzle: connect the entrance and the exit with a single railway line that never branches or crosses itself. Every level on PuzzleWorld is randomly generated and checked by a solver, so there is always exactly one solution.
Easy levels show many pieces from the start; on medium and hard you get fewer hints and bigger grids. Finish the line and a little train runs along your track to the exit.
