Notice the image which says “A pair of aces is a good start”, because two elderly people are sitting there. Think of it like each row being a pre-populated hand (which may be missing some cards) based on the people already sitting there. You pick it and then the “cards” change themselves between stations.
In other words, you pick immediately once the game starts. Look around to see which row you think has the best chance to develop into something good by the time you reach the designated station.
I found myself looking for some rules on how you can influence your "hand" - is it "legal", for example:
- to stand in a specific place in order to (subtly) direct other passengers into a specific section of the car, or
- to take a seat yourself and give it up to an elderly person later on, in an attempt to gain an extra ace ;)
