Understanding my trips to other cities
When I visit other cities through the world exchange, there is a gray person symbol with a number in a red star right next to the city's name sign. What does that number represent?
Also, some cities give gifts for visiting, but this is inconsistent. What triggers these gifts?
Solution 1:
What you are seeing is that users profile image. I believe if you link your game to Facebook that gives that image. The star is their player level. Just as you level up as do others and this just gives you an idea of their level.
The gifts trigger completely randomly. I have tested this and there is no pattern. You can leave and return and sometimes there will be a gift again, or if there wasn't one there could be second time.
