A series of stand alone puzzles that vary from 30 seconds to begin with, to "I-give-up". Fun to kill some spare time. Doesn't come with instructions. You have to deduce the operation of tunnels, gates, and switches. Also has a neat hint feature if you are stumped, and a slow motion feature to better watch the cars scurry around. Object is to line the cars up in proper numerical order behind the engine.
The plot is weak and the ending is disappointing, but it is about the journey. It is a game for hard core puzzle solvers. The graphics are great and the puzzles are varied and demanding. Might be fun for a group of two or three to work together. I have done the Myst and Zork series, but this was too demanding to work alone. However there is an excellent detailed walk through by Dick Leeuw and Louis Koot. Using their walk through I enjoyed the scenery and working the puzzles over a three month period.
