The game attracted 290,000 players on its launch day making it Zynga's largest launch ever at the time of its release. On the 2nd of January it reached the most monthly active users for an application ever on Facebook, beating Farmville's previous record although numbers may drop as its release date was exactly a month prior.
The game allows Facebook members to become the mayor of a virtual city and to oversee its development into a large metropolis. Players can perform tasks, which include farming, construction, and tax collection in their city using energy points. The amount of energy available increases as the user gains in experience levels. The energy points are replenished automatically at a constant rate.
The player can also visit their neighbor's city and perform 5 jobs. This gives the user reputation points which provides the user with free bonus with each reputation level-up and increases the amount of energy, XP and coins bonuses available on a daily basis.
