I've just discovered the endless mode on iOS.
I don't understand the rules that lead the game in this mode.
What is the efficiency count on the upper right corner. What does it represent ?
When does it grow up? What make it decrease?
(As we have to reach efficiency levels, it would help me to understand what this number represent to be able to improve it)
I've seen that people leave the stations after a while. Is it done at random? Or is there a rule behind this? Does it influence the efficiency score?
And when the top efficiency score is reached (above 90), is there a goal to achieve or you just have to look at your metro grid as you can't improve it anymore (no more trains nor carriages nor new lines....)?
Thanks in advance fo any clue o this endless mode
