CityVille Cheats and Tips: Level up and experience guide
Gaining experience and leveling up are central to successfully playing CityVille. Gaining experience allows you to level up. Leveling up unlocks new buildings, expands your energy bar, awards you City Cash, and more. In addition, it's important to level up your Reputation by collecting hearts while helping your neighbors. The higher your Reputation Level, the more goodies and bonuses you'll receive for visiting each neighboring city. You need lots of neighbors to get by in CityVille, so gaining extra bonuses for each neighbor makes your Reputation Level extremely valuable.
