I love metro maps!! It took me a couple tries to figure out how the game worked, but I did eventually clear all the levels. As others have mentioned, a tutorial, or even just a text explanation on the game page would really help!
For anyone who comes here later, here's how to play:
- You need to connect the line color with the correct list of stations (which you can switch with the arrows at the top)
- There is a row of 4 circles: the first is the button you press when you want to submit your answer, the subsequent ones will turn red if you guess wrong. I'm assuming 3 wrong answers will lead to a loss, but I never got that many
- Counting the stations is one way to figure out which line is which
- After you get one, it's about lining up the station names where they intersect
- If I were to compare it to any game, it would probably be a cross-word puzzle, where you have a specific number of spaces to fill, and you need letters to intersect at specific spots (but in this case, they are metro stations :-))
Anyway, I love it :-)
