Yes, you got it. As there are endless production of homeless cards in the game, everybody could send one or more and support the city.
Some of the players as well donate other cards and the city develop own cards.
As some player offer cards for BEER, I donate some BEER to get cards for the city.
The project is still young but we already have generated 30+ USD for the charity!
With next updates, it will be faster each day!
Ok, thanks
